There is limited information available regarding delirium that may occur during the course of electroconvulsive therapy (ECT) in pediatric patients (< 18 years). The aim of this paper is to describe ECT-associated delirium, suspected risk factors, and screening tools that may help in its identification and management. We present a case involving a 15 y.o. African American male who developed ECT-associated delirium during the treatment of catatonia.

Three subtypes of delirium associated with ECT have been described. First, postictal delirium which occurs immediately following ECT and may last up to 1 h; second, post ECT or agitated delirium occurring upon emergence from anesthesia, and interictal delirium which is a prolonged period of disorientation following ECT or it may appear de novo separately from the postictal disorientation period. ECT-associated delirium as a side effect of ECT has been described exclusively in adults. Limited evidence in published literature suggests that predisposing factors may include catatonia, developmental disorders, cerebral vascular disease, parkinson's disease, dementia, bi-temporal electrode placement, high stimulus intensity, and/or prolonged seizures. Patients receiving ECT should be routinely screened for delirium, and if present, for worsening of catatonia with/without NMS throughout their treatment. Patients who develop delirium during ECT should be evaluated for potential underlying etiologies including contributing pharmacological strategies. Clear and consistent definitions of ECT-associated delirium are necessary to improve outcomes.

The paucity of data on perioperative outcomes in low- and middle-income countries complicates the design and implementation of targeted interventions to improve the delivery of safe, affordable, accessible and timely surgical and anaesthesia care services. We assessed perioperative outcomes of patients undergoing surgical care at three Rwandan rural hospitals-Butaro District Hospital, Kirehe District Hospital and Rwinkwavu District Hospital-supported by Partners In Health/Inshuti Mu Buzima-an international non-governmental organisation.

We conducted a 6-month prospective observational cohort study at the three district hospitals. A validated electronic-based perioperative assessment tool was adapted for our setting to capture demographics and clinical information. Descriptive and logistic regression analyses were performed using Stata V.15.1.

A total of 3289 major surgeries were performed from January to September 2020 at the three hospitals. Overall, 3204 surgeries (97.5%) were performed on women; the median age was 27 years (IQR: 23-33), and emergency cases constituted 86.8% of all cases. Cases with the American Society of Anesthesiologists (ASA) status of 3 or above had higher odds of having surgical or anaesthesia complications compared with cases with ASA status 1 (OR: 11.1, 95% CI: 2.7 to 45.8). Furthermore, emergency cases had 1.8 times higher odds of having a composite outcome (developing complications, surgical site infections or death) compared with elective cases (95% CI: 1.1 to 3.0).

Our findings highlight the need for improving surgical capacity, reinforcing infection prevention and control measures and leveraging electronic data capture for quality improvement to ensure safer surgery and anaesthesia care in rural Rwanda.

The incidence of colorectal cancer is expected to increase, particularly among patients with significant frailty and comorbidities. A subgroup of these patients may not be suitable for surgery because of the high risk of postoperative morbidity and mortality.

The aim of this study was to characterize the clinical outcomes, management, social status, and survival of patients deemed nonoperable because of comorbidity and/or frailty.

This was a retrospective cohort study.

Overall survival was estimated using the Kaplan-Meier method. The Cox proportional-hazards model was used to estimate HRs and 95% CIs for mortality-associated modifiable risk factors.

Patients diagnosed with resectable colorectal cancer but deemed nonoperable because of comorbidity and/or frailty by a multidisciplinary team between January 1, 2020, and April 30, 2024, were included in this study.

The primary outcome was to describe the current population, investigate mortality, and explore mortality-related risk factors in the current population.

During the study period, 69 of 1667 patients who had colorectal cancer that was potentially resectable but who were deemed nonoperable were included in the study population. The rate of 90-day and 1-year mortality was 20% and 52%, respectively. Three years after the diagnosis, 12% of the patients were alive. At the time of diagnosis, anemia was found in 73% of female patients and 71% of male patients. In addition, 77% of the patients had hypoalbuminemia. Lower albumin levels were associated with poor survival (HR, 0.92; 95% CI, 0.88-0.98; p = 0.007).

The retrospective nature and small sample size inherently limit the generalizability of the study findings.

Mortality in the current population was high. However, our findings highlight potential areas for improvement in the management of these patients. See Video Abstract .

Retrospective Review of a National Database.

By utilizing a national database, this study aims to quantify the predictors of 30-day mortality after odontoid fixation and guide appropriate management for patients in whom the choice between operative and non-operative management is unclear.

The American College of Surgeons National Surgical Quality Improvement Database was queried using Current Procedural Terminology (CPT) codes and International Classification of Disease (ICD) codes to identify patients 60 or older who underwent surgical fixation of an odontoid fracture from 2005 to 2020. Risk factors for mortality significant in univariate and subsequent multivariate analysis were used to develop a scoring system to predict post-operative mortality.

608 patients were identified. Patients were split into a non-mortality 30 days post-op group, and into a mortality 30 days post-op group. The following risk factors were included in the scoring system: functional dependency, disseminated cancer, albumin less than 3.5, WBC count greater than 16 k, anterior surgical approach, and pre-op SIRS. Using a cutoff value of 2, the CAAD-16 score had a sensitivity and specificity of 82% and 81%, respectively. The ASA score, cutoff at 4, showed a sensitivity and specificity of 64% and 75% respectively.

This sample of 294 patients represents one of the largest samples of odontoid fracture fixation patients available in the literature and comes from a nationally representative database. We structure relevant risk factors into the CAADS-16 score, which has the potential to be a clinically relevant tool to prevent short-term postoperative mortality.

To examine the association between surgeon gender and early postoperative complications, including 30-day death and readmission, in elective surgery.

Variations between male and female surgeon practice patterns may be a source of bias and gender inequality in the surgical field, perhaps impacting the quality of care. However, there are limited and conflicting studies regarding the association between surgeon gender and postoperative outcomes.

MEDLINE and Embase were searched in October 2023 for observational studies, including patients who underwent elective surgery requiring general or regional anesthesia across multiple surgical specialties. Multiple independent blinded reviewers oversaw the data selection, extraction, and quality assessment according to the PRISMA, MOOSE, and Newcastle Ottawa Scale guidelines. Data were pooled as odds ratios, using a generic inverse-variance random-effects model.

Of 944 abstracts screened, 11 studies were included in this systematic review and meta-analysis. A total of 4,440,740 postoperative patients were assessed for a composite primary outcome of mortality, readmission, and other complications within 30 days of elective surgery, with a total of 325,712 (7.3%) surgeries performed by 7072 (10.9%) female surgeons. There was no association between surgeon gender and the composite of mortality, readmission, and/or complications (odds ratio=0.97, 95% CI 0.95-1.00; I2 =64.9%; P =0.001).

These results support that surgeon gender is not associated with early postoperative outcomes, including mortality, readmission, or other complications in elective surgery. These findings encourage patients, health care providers, and stakeholders not to consider surgeon gender as a risk factor for postoperative complications.

For urgent and emergent colectomies, return to the operating room is interpreted as a negative quality indicator. We sought to describe indications, procedures performed, and outcomes of patients undergoing reoperation after colectomy.

Retrospective study of patients undergoing urgent and emergent colectomy with re-operation at a single institution from 2013 to 2023. Details of the patients and surgeries indexed.

117 patients met the study criteria. Sepsis prior to surgery was noted in 29 ​% of patients, intraoperative vasopressors were used in 80 ​% and 52 ​% were left in gastrointestinal discontinuity. Among re-operations, 60 ​% of patients underwent a "planned second look", 17 ​% had a supportive procedure, and 23 ​% had an unplanned re-operation, the latter group most reflective of surgical complications.

Patients undergoing urgent and emergent colectomies are very ill at presentation. Planned second look and supportive procedures account for most re-operations, suggesting the current utilization of re-operation as a quality indicator is flawed.

Emergency surgery in patients with colorectal cancer (CRC) is associated with elevated mortality and morbidity compared to elective operations. This study was conducted to identify the factors influencing both short and long term outcomes in emergent CRC operations, particularly in critically ill patients.

This single center retrospective analysis focuses on patients with stage III or higher CRC who underwent emergency surgery and were admitted to the intensive care unit postoperatively.

Among 64 patients, 46 presented with generalized peritonitis due to free perforation. Non-survivors at 90 days had a higher incidence of preoperative shock (53.3% vs. 4.1%, P = 0.000), elevated perioperative Sequential Organ Failure Assessment scores (P = 0.000; P = 0.013), and fewer retrieved lymph nodes (LN) (P = 0.010). Multivariate analysis identified LNs retrieval as a significant predictor of 90-day mortality (AUC = 0.727). For overall survival, younger age, lower American Society of Anesthesiologists (ASA) physical status, absence of metastasis, adjuvant chemotherapy (CTx), and lower LN ratio (LNR) were associated with improved outcomes. Multivariate analysis showed ASA physical status and adjuvant CTx as significant predictors. In predicting 3-year recurrence (51% of patients), the Random Forest model achieved 65% accuracy. Age and LNR were major predictors, with 0.01 unit increase in LNR raising recurrence risk by 1.025-fold and each additional year of age by 1.035-fold.

The number of retrieved LNs was identified as a predictor of 90 day survival, ASA physical status and adjuvant CTx were identified as prognostic factors for overall survival, and age and the LNR were found to be predictors of disease recurrence within three years.

Emergency colorectal surgery has a high incidence of postdischarge complications, and loss to follow-up can delay the identification of complications. Amid evolving postdischarge care practices, it is important to assess predictors of loss to follow-up. We aimed to characterize the predictors of loss to follow-up.

We conducted a retrospective institutional cohort study of patients ≥18 years undergoing emergency colorectal surgery at a tertiary hospital from 2016 to 2022. We excluded patients with in-hospital or 30-day mortality or a postoperative stay >30 days. We defined loss to follow-up as the absence of a postdischarge 30-day in-person or telehealth visit. The predictors of loss to follow-up were evaluated using stepwise regression analysis. We performed a subgroup analysis evaluating predictors of loss to follow-up among patients discharged post-telehealth availability at our institution (March 2020).

We included 426 patients, of whom 95 (22.3%) were loss to follow-up and 58.9% were discharged post-telehealth availability. Almost one half of patients were female (52.3%), and the majority were of White race (89.2%), and non-Hispanic (92.0%). Being male, being discharged to a skilled nursing facility, and prolonged hospitalization were risk factors for loss to follow-up, whereas receiving home care visits was protective. Post-telehealth availability, being male, and prolonged hospitalization were risk factors for loss to follow-up, whereas receiving homecare visits was protective. Patients who had a follow-up visit were less likely to be readmitted to the hospital and have a visit to the emergency department.

Receiving home care visits was the most protective factor for preventing loss to follow-up. Living far from the hospital remained a risk factor even post-telehealth availability. High-risk patients may benefit from targeted interventions that include scheduled home care visits.

The Distressed Communities Index (DCI) is a stratification tool that captures socioeconomic disparities based on zip code. To date, no prior study has investigated the association of DCI score and inguinal hernia repair outcomes. This study aims to evaluate the association between DCI score and 30-day outcomes following inguinal hernia repair using the Abdominal Core Health Quality Collaborative (ACHQC) database. We hypothesize that patients with higher DCI scores will have a higher number of comorbidities and 30-day postoperative events.

All patients who underwent inguinal hernia repair from 2015 to 2023 with an available DCI score and 30-day follow-up data available were included. Patients were stratified into DCI quintiles based on zip code. Primary outcomes of interest were 30-day hernia-specific postoperative outcomes. Pearson's chi-squared and Kruskal-Wallis tests were used to compare DCI scores with comorbid conditions and perioperative outcomes.

30,927 patients were included for analysis; 12,206 patients were classified as prosperous (40%), 7190 patients as comfortable (23%), 4884 patients as mid-tier (16%), 3485 patients as at-risk (11%), and 3162 as distressed (10%). Distressed patients were more likely to have ASA 3 or higher and comorbidities including hypertension, diabetes, ESRD, and COPD (p < 0.001). Patients with higher DCI scores were significantly more likely to undergo an emergency operation and have a longer OR time (p < 0.001). Distressed patients were also more likely to experience a major wound complication requiring readmission (p = 0.05) and reoperation (p < 0.001).

DCI scores are strongly linked to surgical risk and outcomes following inguinal hernia repair. Special consideration should be given to DCI scores when optimizing patients prior to inguinal hernia repair.

Cauda equina syndrome (CES) is a rare but life-altering disease resulting from compression of the nerve roots at the spinal cord's terminus. CES typically presents with low back pain, sciatica, sensorimotor deficits, and bowel and bladder dysfunction. Owing to its rarity, the condition is often missed, leading to significant morbidity and potential legal implications for physicians.

This review synthesizes the current literature on CES, including its epidemiology, pathophysiology, classifications, and management strategies. Emphasis is placed on the diagnosis and treatment of CES as well as the legal implications of CES for spine surgeons.

The literature reveals variability in the reported prevalence of CES, with incidence rates ranging from 0.34 to 7 per 100,000 individuals annually. The timing of decompression remains debated. Some studies report no significant difference in outcomes between decompression within 24 hours vs. 48 hours, while others emphasize the importance of immediate intervention. Legal cases related to CES frequently involve delayed diagnosis, with significant ramifications for physicians.

Surgical decompression remains the definitive treatment of CES, though the timing of surgery requires careful consideration to balance the urgency of intervention with the risks of complications. Further research is needed to explore strategies that would allow for improvement in identifying and treating patients with CES in a timely manner.

Enterostomy is utilized to mitigate severe clinical symptoms in children with very early-onset inflammatory bowel disease (VEO-IBD) and to provide a window for stem cell transplantation. Nevertheless, the incidence of postoperative complications is significant, and there is currently a lack of research exploring the risk factors associated with complications related to the stoma and incision following the procedure. The objective of this study is to investigate the risk factors for stoma and incision complications after enterostomy in patients with VEO-IBD. From January 2015 to December 2023, 49 children with VEO-IBD who underwent enterostomy were enrolled in the study. Demographic characteristics, blood biochemical indices, weighted Pediatric Crohn's Disease Activity Index (wPCDAI), and enterostomy-related information were prospectively collected. Multivariate logistic regression was employed to identify the risk factors for ostomy and incision-related complications. All 49 included VEO-IBD children had interleukin-10 (IL-10) signaling defects, with 27 (55.1%) having stomal-related complications and 10 (20.4%) had incision complications after enterostomy. Univariate analysis revealed that wPCDAI (OR, 1.03; 95% CI, 1.00-1.07; P = 0.05) showed a tendency towards statistical significance in the occurrence of ostomy complications. Weight-for-age Z-score (WAZ) (OR, 0.57; 95% CI, 0.39-0.84; P = 0.004), height-for-age Z-score (HAZ) (OR, 0.57; 95% CI, 0.37-0.88; P = 0.01), type of surgery (OR, 0.12; 95% CI, 0.03-0.56, P = 0.007), C-reactive protein (CRP) (OR, 1.02; 95% CI, 1.01-1.04; P = 0.007), and wPCDAI (OR, 1.08; 95% CI, 1.01-1.14; P = 0.009) demonstrated statistical significance in the occurrence of incision complications. However, multivariate binary logistic regression did not reveal any statistically significant factors.

Although emergency surgery is unavoidable, our study suggests that improving nutritional status, reducing CRP levels, and increasing preoperative wPCDAI scores may help reduce post-enterostomy stoma and incision complications in VEO-IBD children with interleukin-10 (IL-10) signaling defects. Further large-scale studies are needed to confirm these findings.

• Enterostomy is commonly used to manage severe symptoms in children with VEO-IBD and to provide a window for stem cell transplantation. • The incidence of postoperative complications, including stoma and incision-related issues, is significant in these patients.

• This study identifies potential risk factors for stoma and incision complications following enterostomy in children with VEO-IBD, particularly those with IL-10 signaling defects. • Factors such as nutritional status (WAZ and HAZ), CRP levels, type of surgery, and the wPCDAI were found to be associated with stoma and incision complications in univariate analysis, although multivariate analysis did not show statistical significance for these factors.

There are 2 degree programs for licensed physicians in the US: allopathic medical doctorate (MD) and osteopathic doctorate (DO). However, evidence is limited as to whether outcomes differ between patients treated by MD vs DO surgeons.

To evaluate differences in surgical outcomes and practice patterns by surgeon medical school training (MD vs DO).

This retrospective cohort study used 100% Medicare claims data from inpatient hospitals providing surgical services from January 1, 2016, to December 31, 2019 among Medicare fee-for-service beneficiaries aged 65 to 99 years who underwent 1 of the 14 most common surgical procedures. Data analysis was performed from January 17, 2023, to August 13, 2024.

Medical school degree (MD vs DO).

The primary outcome was 30-day mortality, and the secondary outcomes were readmissions and length of stay. To assess differences between surgeons by medical school training, a multivariable linear probability model was used, which was adjusted for hospital fixed effects and patient, procedure, and surgeon characteristics.

Of the 2 360 108 total surgical procedures analyzed, 2 154 562 (91.3%) were performed by MD surgeons, and 205 546 (8.7%) were performed by DO surgeons. Of 43 651 total surgeons, most surgeons were MDs (39 339 [90.1%]), the median (SD) age was 49.0 (9.8) years, and 6649 surgeons (15.2%) were female. The mean (SD) age of patients undergoing surgical procedures was 74.9 (6.7) years, 1 353 818 of 2 360 108 patients (57.4%) were female, and 2 110 611 patients (89.4%) self-reported as White. DO surgeons were significantly more likely to operate on older patients (DO patient mean [SD] age: 75.3 [7.1] years; MD patient mean [SD] age: 74.8 [6.6]), female patients (DO: 60.2% of patients; MD: 57.1% of patients), and Medicaid dual-eligible patients (DO: 10.3% of patients; MD: 8.6% of patients). DOs performed a lower proportion of elective operations (DO: 74.2% vs MD: 80.2%) and were more likely to work in public hospitals (DO: 10.3%; MD: 9.5%) and nonteaching hospitals (DO: 57.9%; MD: 68.1%). There was no evidence that 30-day mortality differed between MD and DO surgeons (adjusted mortality rate, DO: 1.61%; MD: 1.58%; absolute risk difference [aRD], -0.04 percentage points; 95% CI, -0.11 to 0.04; P = .37). On secondary analyses, no difference was found in 30-day readmissions or length of stay between MD and DO surgeons.

In this retrospective cohort study using Medicare data, there was no evidence that patient outcomes differed between MD and DO surgeons for common operations after adjusting for patient factors and practice settings.

Tibiotalocalcaneal (TTC) arthrodesis is an established treatment for osteoarthritis (OA), offering stabilization and earlier weightbearing. However, its role in managing traumatic fractures (TFs) remains controversial because of higher risks of complications. This study aimed to compare complication rates, readmissions, and predictors of adverse outcomes in TTC arthrodesis performed for OA vs TF using a national database.

A retrospective cohort study was conducted using the Nationwide Readmissions Database (2016-2021). Patients undergoing TTC arthrodesis were identified via International Classification of Diseases, Tenth Revision (ICD-10) codes and stratified by indication (OA or TF). Primary outcomes included complication rates, 30- and 90-day readmissions, and revision surgeries. Multivariable logistic regression identified independent predictors of complications. Propensity score matching (PSM) was performed to account for baseline differences.

TF cases exhibited significantly higher complication rates (54.5% vs 16.0%, P < .001), including malunion (11% vs 2%, P < .001) and cellulitis (5% vs 1%, P < .001). Readmission rates were also elevated in TF patients at 30 days (17% vs 3%, P < .001) and 31-90 days (14% vs 4.8%, P < .001). Logistic regression identified chronic kidney disease, diabetes, and obesity as independent predictors of complications. PSM confirmed these findings, demonstrating significantly higher rates of complications and readmissions in TF patients.

Findings indicate that TTC arthrodesis for TF is associated with higher risks of complications and readmissions compared with OA, attributable to acute injury characteristics and surgical complexity. Chronic comorbidities further exacerbate these risks. Optimizing perioperative management and timing of surgery in TF patients may mitigate complications. This study highlights the need for individualized care strategies to improve outcomes in TTC arthrodesis for trauma.

Level III, therapeutic: case-control study.

Outcomes of patients with opioid use disorder undergoing elective procedures have been well studied, but research is lacking in the orthopaedic trauma population.

The aim was to compare perioperative pain and morphine equivalents required by patients with versus without opioid use disorder following intramedullary nail fixation of femoral or tibial fractures.

We conducted a retrospective review of all patients with isolated femoral or tibial diaphyseal fractures treated with intramedullary nail fixation. Outcomes were compared between patients with diagnosed opioid use disorder and controls without, including daily morphine equivalents and patient-reported pain scores.

Patients with opioid use disorder (n = 42) required greater morphine equivalents and reported higher pain than controls (n = 42) at all time points but did not differ in change of morphine equivalents over the perioperative period.

This highlights the challenge of perioperative pain control in this population and need for improved specific pain management protocols.

Emergency laparotomy (EL) is associated with high morbidity and mortality, often exceeding 10%. This study evaluated the impact of the EMergency Laparotomy Audit (EMLA) interdisciplinary perioperative pathway on patient outcomes, hospital costs and length of stay (LOS) within a single centre.

A prospective cohort study was conducted from August 2020 to July 2023. The intervention team included specialist clinicians, hospital administrators and an in-hospital quality improvement team. Patients who underwent EL were divided into a pre-intervention control group (n=136) and a post-intervention group (n=293), and an 8-item bundle was implemented. Propensity scoring with a 1:1 matching method was utilised to reduce confounding and selection bias. The primary outcomes examined were LOS, hospitalis-ation costs and surgical morbidity, while secondary outcomes included 30-day mortality and adherence to the intervention protocol.

The utilisation of the EMLA perioperative care bundle led to a significant reduction in surgical complications (34.8% to 20.6%, P<0.01), a decrease in LOS by 3.3 days (15.4 to 12.1 days, P=0.03) and lower hospitalisation costs (SGD 40,160 to 30,948, P=0.04). Compliance with key interventions also showed improvement. However, there was no difference in 30-day mortality.

This study offers insights on how surgical units can implement systemic perioperative changes to improve outcomes for patients undergoing emergency laparotomy.

Poorer postoperative outcomes have been observed for patients admitted and operated on later in the week and over the weekend. This is thought to be related to temporal fluctuations in the quality of perioperative care. The aim of this work was to identify if the day of surgery influenced outcomes in a national cohort of colorectal cancer (CRC) resections.

A retrospective population-based study of patients undergoing CRC resection during the period 2010-2020 in Aotearoa New Zealand (AoNZ) was conducted. Ninety-day postoperative mortality, morbidity, postoperative length of stay (PLOS), reoperation and failure to rescue (FTR) were calculated for elective and acute cohorts, stratified by the day of surgery. FTR-Surgical (mortality following reoperation within 90 days of the index operation) was also analysed by day of reoperation. Univariable and mixed-effects, multivariate, logistic regression models were analysed.

The overall cohort included 17 174 patients who underwent surgery for CRC. The 90-day mortality in the elective and acute cohorts was 2.4% (336/13 744) and 11% (371/3430), respectively. Ninety-day mortality, inpatient complications, FTR and PLOS did not differ by day of surgery in acute and elective cohorts. Notably, patients having elective surgery on a Wednesday had a significantly higher rate of reoperation (OR 1.29, 95% CI 1.06-1.56, p = 0.012). Furthermore, reoperation following complication of the index surgery was associated with a significantly higher 90-day mortality (FTR-Surgical) for patients having reoperation on a Friday (OR 2.10, 95% CI 1.01-4.33, p = 0.045).

There is no variation in postoperative outcomes across the week for both elective and emergency cases. This study does, however, highlight a higher FTR-S later on Friday, suggesting that these high-risk patients may require closer postoperative monitoring over the weekend.

Disparities secondary to underinsurance present throughout the surgical care continuum. Community free clinics are uniquely capable to provide health care services to the medically underserved, but surgery often falls outside their scope of care.

Retrospective chart review was conducted on consecutive community free clinic patients receiving free surgical services via referral to a partnering ambulatory surgery center between March 2016 and September 2021. Those with documented contact information were recruited 1-3 years post-procedure for long-term quality-of-life (LTQOL) outcomes assessment via modified Veterans RAND 12-item health survey.

Of 142 included patients, 95.7% identified as Hispanic/Latino and 75.6% were uninsured. Twelve patients had cancerous or precancerous lesions detected and/or removed through diagnostic or definitive procedures. 3.5% experienced postoperative complication including bacterial (n = 2) or fungal (n = 1) surgical site infection and wound dehiscence (n = 2). With a 48.9% response rate, no significant differences in sociodemographic or clinical characteristics were found between surveyed vs non-surveyed patients. Of surveyed patients, 59.7% and 52.2% reported pre-/post-operative improvement in physical health and emotional health, respectively.

Free diagnostic screening procedures provided timely diagnoses while free definitive surgeries safely and positively impacted long-term patient-reported physical health. Longitudinal, multidisciplinary follow-up and social support may be warranted to concurrently improve emotional and mental health in similarly underinsured populations.

Open groin vascular surgeries are important in managing peripheral arterial diseases. Given its inherent risks and the diverse patient profiles, there is a need for risk assessment tools. This study aimed to develop a 30-d point-scoring risk calculator for patients undergoing open groin vascular surgeries.

Patients underwent open groin vascular surgery, including aortobifemoral, axillofemoral, femorofemoral, iliofemoral, femoral-popliteal, and femoral-tibial bypass as well as thromboendarterectomy, were identified in American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2021. Patients were randomly sampled into experimental (2/3) and validation (1/3) groups. The George Washington (GW) groin score, a weighted point-scoring system, was developed for 30-d mortality from multivariable regression on preoperative risk variables by Sullivan's method. GW groin score was subjected to internal and external validation. Furthermore, the effectiveness of GW groin score was evaluated in 30-d major surgical complications.

A total of 129,424 patients were analyzed, with 86,715 allocated to experimental group and 42,709 to validation group. GW groin score is derived as follows: aortobifemoral bypass (2 points), axillofemoral bypass (1 point), age (>75 y, 2 points; 65-75 y, 1 point), disseminated cancer (2 points), emergent presentation (1 point), American Society of Anesthesiology score 4 or 5 (1 point), dialysis (1 point), and preoperative sepsis (1 point).GW groin score exhibited robust discrimination (c-statistic = 0.794, 95% CI = 0.786-0.803) and calibration (Brier score = 0.029). The transition from individual preoperative variables (c-statistic = 0.809, 95% CI = 0.801-0.818) to the point-scoring system was successful and external validation of the score was confirmed (c-statistic = 0.789, 95% CI = 0.777-0.801, Brier score = 0.030). Furthermore, GW groin score can effectively discriminate major surgical complications.

This study developed GW groin score, a concise and comprehensive 10-point risk calculator. This well-validated score demonstrates robust discriminative and predictive abilities for 30-d mortality and major surgical complications following open groin vascular surgeries. GW groin score can anticipate potential perioperative complications and guide treatment decisions.

The objective of this study was to describe the all-cause mortality rate in cats hospitalized by the soft tissue surgery service of an academic referral hospital over a 5-year period and to identify specific risk factors for mortality. The hypotheses were that the all-cause mortality rate during hospitalization would be low, and cats undergoing emergency surgery and those with an American Society of Anesthesiologists (ASA) status of 3 or more would be at increased risk for mortality.

The case log of cats hospitalized by the soft tissue surgery service at the University of Georgia was searched retrospectively to identify all cats hospitalized in the years 2015-2020. Data collected about each cat included age, sex and neuter status, weight, body condition score (1-9), pre-existing heart disease, chronic kidney disease, concurrent infection or cancer, emergency status, time of surgery (daytime vs after hours, which was defined as after 4 pm), if the surgery was performed on a weekday or weekend, and general type of surgery. Univariable logistic regressions were implemented to test and estimate odds ratios for the effects of risk factors on in-hospital mortality. A multivariable logistic regression was developed that initially included all risk factors with P <0.05 on univariable analysis. Log-likelihood ratio test P values and profile-likelihood confidence intervals were reported.

The all-cause mortality rate was 6.1%. Analysis was limited because of low mortality, but multivariable analysis identified increasing ASA status and emergency surgery as significant risk factors for increased mortality while hospitalized.

The findings of this study confirmed that increasing ASA status and emergency procedures are significant risk factors for mortality in cats. Clinicians should be aware of these risk factors and consider how to best monitor and manage these feline patients.

Background: Surgeries represent a mainstay of medical care globally. Patterns of complications are frequently recognized late and place a considerable burden on health care systems. The aim was to develop and test the first deep learning-adjusted CUSUM program (DL-CUSUM) to predict and monitor in-hospital mortality in real time after liver transplantation. Methods: Data from 1066 individuals with 66,092 preoperatively available data point variables from 2004 to 2019 were included. DL-CUSUM is an application to predict in-hospital mortality. The area under the curve for risk adjustment with Model of End-stage Liver Disease (D-MELD), Balance of Risk (BAR) score, and deep learning (DL), as well as the ARL (average run length) and control limit (CL) for an in-control process over 5 years, were calculated. Results: D-MELD AUC was 0.618, BAR AUC was 0.648 and DL model AUC was 0.857. CL with BAR adjustment was 2.3 with an ARL of 326.31. D-MELD reached an ARL of 303.29 with a CL of 2.4. DL prediction resulted in a CL of 1.8 to reach an ARL of 332.67. Conclusions: This work introduces the first use of an automated DL-CUSUM system to monitor postoperative in-hospital mortality after liver transplantation. It allows for the real-time risk-adjusted monitoring of process quality.

The use of extracorporeal life support (ECLS) throughout the perioperative phase of lung transplantation requires nuanced planning and execution by an integrated team of multidisciplinary experts. To date, no multidisciplinary consensus document has examined the perioperative considerations of how to best manage these patients. To address this challenge, this perioperative utilization of ECLS in lung transplantation consensus statement was approved for development by the International Society for Heart and Lung Transplantation Standards and Guidelines Committee. International experts across multiple disciplines, including cardiothoracic surgery, anesthesiology, critical care, pediatric pulmonology, adult pulmonology, pharmacy, psychology, physical therapy, nursing, and perfusion, were selected based on expertise and divided into subgroups examining the preoperative, intraoperative, and postoperative periods. Following a comprehensive literature review, each subgroup developed recommendations to examine via a structured Delphi methodology. Following 2 rounds of Delphi consensus, a total of 39 recommendations regarding intraoperative considerations for ECLS in lung transplantation met consensus criteria. These recommendations focus on the planning, implementation, management, and monitoring of ECLS throughout the entire intraoperative period.

Enhanced recovery after surgery (ERAS) protocols are an evidence-based, multidisciplinary, and systematic approach to peri-operative care, which attempt to reduce the anticipated physiological strain on patients after major surgery. This meta-analysis of randomised clinical trials (RCTs) evaluated the impact of ERAS following emergency laparotomy versus standard care.

A systematic review was performed as per PRISMA guidelines. Meta-analysis was performed using RevMan v5.4.

Six RCTs involving 509 patients were included. Patients randomised to ERAS had reduced post-operative nausea and vomiting (PONV) (odds ratio (OR): 0.32, 95 ​% confidence interval (CI): 0.20-0.51), time to ambulation (mean difference (MD): 1.67, 95 ​% CI: -2.56 to -0.78) and bowel opening (MD: -1.26, 95 ​% CI: -2.03 to -0.49), length of stay (LOS) (MD: -2.92 95 ​% CI: -3.73 - - 2.10), pulmonary complications (OR: 0.43, 95 ​% CI: 0.24-0.75), surgical site (OR: 0.33 95 ​% CI: 0.2-0.50) and urinary tract infections (OR: 0.48 95 ​% CI: 0.19-1.16).

ERAS successfully reduced patient recovery, LOS, and complications. ERAS protocols should be deployed, where feasible, for emergency laparotomy.

Small bowel obstruction (SBO) is one of the most frequent causes of general emergency surgery. The 30-day mortality rate post-surgery ranges widely from 2 to 30%, contingent upon the patient population, which renders risk assessment tools helpful. this study aimed to develop a 30-day point-scoring risk calculator designed for patients undergoing SBO surgery. Patients who underwent SBO surgery were identified in the ACS-NSQIP database from 2005 to 2021. Patients were randomly sampled into an experimental (2/3) and a validation (1/3) group. A weighted point scoring system was developed for the risk of 30-day mortality, utilizing multivariable regression on preoperative risk variables based on Sullivan's method. The risk scores underwent both internal and external validation. Furthermore, the efficacy of the risk score was evaluated in 30-day major surgical complications. A total of 93,517 patients were identified, with 63,521 and 29,996 assigned to the experimental and validation groups, respectively. The risk calculator is structured to assign points based on age (> 85 years, 4 points; 75-85 years, 3 points; 65-75 years, 2 points; 55-65 years, 1 point), disseminated cancer (2 points), American Society of Anesthesiology (ASA) score of 4 or 5 (1 point), preoperative sepsis (1 point), hypoalbuminemia (1 point), and fully dependent functional status (1 point). The risk calculator showed strong discrimination (c-statistic = 0.825, 95% CI 0.818-0.831) and good calibration (Brier score = 0.043) in the experimental group. The point scoring system was successfully translated from individual preoperative variables (c-statistic = 0.840, 95% CI 0.834-0.847) and was externally validated in ACS-NSQIP (c-statistic = 0.827, 95% = CI 0.834-0.847, Brier score = 0.043). The SBO risk score can effectively discriminate major surgical complications including major adverse cardiovascular events (c-statistic = 0.734), cardiac complications (c-statistic = 0.732), stroke (c-statistic = 0.725), pulmonary complications (c-statistic = 0.727), renal complications (c-statistic = 0.692), bleeding (c-statistic 0.674), sepsis (c-statistic = 0.670), with high predictive accuracy (all Brier scores < 0.1). This study developed and validated a concise yet robust 10-point risk scoring system for patients undergoing SBO surgery. It can be informative to determine treatment plans and to prepare for potential perioperative complications in patients undergoing SBO surgery.

Obesity, sarcopenia, and myosteatosis in inflammatory bowel disease may confer negative outcomes, but their prevalence and impact among patients with Crohn's disease (CD) have not been systematically studied. The aim of this study was to assess nutritional status and body composition among patients undergoing resectional surgery for CD and determine impact on operative outcomes.

Consecutive patients with CD undergoing resection from 2000 to 2018 were studied. Total, subcutaneous, and visceral fat areas and lean tissue area (LTA) and intramuscular adipose tissue (IMAT) were determined preoperatively by computed tomography at L3 using SliceOmatic (Tomovision, Canada). Univariable and multivariable linear, logistic, and Cox proportional hazards regression were performed.

One hundred twenty-four consecutive patients were studied (ileocolonic disease 53%, n = 62, biologic therapy 34.4% n = 43). Mean fat mass was 22.7 kg, with visceral obesity evident in 23.9% (n = 27). Increased fat stores were associated with reduced risk of emergency presentation but increased corticosteroid use (β 9.09, standard error 3.49; P = .011). Mean LBM was 9.9 kg. Sarcopenia and myosteatosis were associated with impaired baseline nutritional markers. Myosteatosis markers IMAT (P = .002) and muscle attenuation (P = .0003) were associated with increased grade of complication. On multivariable analysis, IMAT was independently associated with increased postoperative morbidity (odds ratio [OR], 1.08; 95% confidence interval (CI), 1.01-1.16; P = .037) and comprehensive complications index (P = .029). Measures of adiposity were not associated with overall morbidity; however, increased visceral fat area independently predicted venous thromboembolism (OR, 1.02; 95% CI, 1.00-1.05; P = .028), and TFA was associated with increased wound infection (OR, 1.00; 95% CI, 1.00-1.01; P = .042) on multivariable analysis.

Myosteatosis is associated with nutritional impairment and predicts increased overall postoperative morbidity following resection for CD. Despite its association with specific increased postoperative risks, increased adiposity does not increase overall morbidity, reflecting preservation of nutritional status and relatively more quiescent disease phenotype. Impaired muscle mass and function represent an appealing target for patient optimization to improve outcomes in the surgical management of CD.

Environmental hazards may influence health outcomes and be a driver of health inequalities. We sought to characterize the extent to which social-environmental inequalities were associated with surgical outcomes following a complex operation.

In this cross-sectional study, patients who underwent abdominal aortic aneurysm repair, coronary artery bypass grafting, colectomy, pneumonectomy, or pancreatectomy between 2016 and 2021 were identified from Medicare claims data. Patient data were linked with social-environmental data sourced from Centers for Disease Control and Agency for Toxic Substances and Disease Registry data based on county of residence. The Environmental Justice Index social-environmental ranking (SER) was used as a measure of environmental injustice. Multivariable regression analysis was performed to assess the relationship between SER and surgical outcomes.

Among 1,052,040 Medicare beneficiaries, 346,410 (32.9%) individuals lived in counties with low SER, while 357,564 (33.9%) lived in counties with high SER. Patients experiencing greater social-environmental injustice were less likely to achieve textbook outcome (odds ratio 0.95, 95% confidence interval 0.94-0.96, P < 0.001) and to be discharged to an intermediate care facility or home with a health agency (odds ratio 0.97, 95% confidence interval 0.96-0.98, P < 0.001).

Cumulative social and environmental inequalities, as captured by the Environmental Justice Index SER, were associated with postoperative outcomes among Medicare beneficiaries undergoing a range of surgical procedures. Policy makers should focus on environmental, as well as socioeconomic injustice to address preventable health disparities.

Care fragmentation has been shown to lead to increased morbidity and mortality. We aimed to explore the factors related to care fragmentation after hospital discharge in geriatric emergency general surgery patients, as well as examine the association between care fragmentation and mortality.

We designed a retrospective study of the Nationwide Readmissions Database 2019. We included patients ≥65 years old admitted with an emergency general surgery diagnosis who were discharged alive from the index admission. The primary outcome was 90-day care fragmentation, defined as an unplanned readmission to a non-index hospital. Multivariable logistic regression was performed, adjusting for patient and hospital characteristics.

A total of 447,027 older adult emergency general surgery patients were included; the main diagnostic category was colorectal (22.6%), and 78.2% of patients underwent non-operative management during the index hospitalization. By 90 days post-discharge, 189,622 (24.3%) patients had an unplanned readmission. Of those readmitted, 20.8% had care fragmentation. The median age of patients with care fragmentation was 76 years, and 53.2% were of female sex. Predictors of care fragmentation were living in rural counties (odds ratio 1.76, 95% confidence interval: 1.57-1.97), living in a low-income ZIP Code, discharge to intermediate care facility (odds ratio 1.28, 95% confidence interval: 1.22-1.33), initial non-operative management (odds ratio 1.17, 95% confidence interval: 1.12-1.23), leaving against medical advice (odds ratio 2.60, 95% confidence interval: 2.29-2.96), and discharge from private investor-owned hospitals (odds ratio 1.18, 95% confidence interval: 1.10-1.27). Care fragmentation was significantly associated with higher mortality.

The burden of unplanned readmissions in older adult patients who survive an emergency general surgery admission is underestimated, and these patients frequently experience care fragmentation. Future directions should prioritize evaluating the impact of initiatives aimed at alleviating the incidence and complications of care fragmentation in geriatric emergency general surgery patients.

The impact of Covid-19 on surgical patients worldwide has been substantial. In the United Kingdom (UK) and the Republic of Ireland (RoI), the first wave of the pandemic occurred in March 2020. The aims of this study were to: (1) evaluate the volume of neurosurgical operative activity levels, Covid-19 infection rate and mortality rate in April 2020 with a retrospective cross-sectional cohort study conducted across 16 UK and RoI neurosurgical centres, and (2) compare patient outcomes in a single institution in April-June 2020 with a comparative cohort in 2019. Across the UK and RoI, 818 patients were included. There were 594 emergency and 224 elective operations. The incidence rate of Covid-19 infection was 2.6% (21/818). The overall mortality rate in patients with a Covid-19 infection was 28.6% (6/21). In the single centre cohort analysis, an overall reduction in neurosurgical operative activity by 65% was observed between 2020 (n = 304) and 2019 (n = 868). The current and future impact on UK neurosurgical operative activity has implications for service delivery and neurosurgical training.

Patients undergoing emergency abdominal surgery for inflammatory bowel disease (IBD) are a complex cohort who are relatively poorly represented in published literature. This is partly due to the lack of consensus of the definition of the term emergency in IBD surgery. There is ongoing and recent work defining clinical urgency for unplanned surgical procedures and categorizing the high-risk surgical patient. This paper aims to report the difference in patient metrics and risks as recorded by the National Emergency Laparotomy Audit (NELA).

Complete patient data, including histology, were available in the NELA database between 2013 and 2016. Urgency categories recorded by NELA are <2 h, 2-6 h, 6-18 h, and >18 h. Patient characteristics, physiology, biochemistry, and outcomes are reported according to these urgency categories with regression analysis used to compare differences between them.

Mortality in Crohn's disease (CD) ranged from 1.4% in the >18 h urgency to 14.6% in the most urgent. In ulcerative colitis (UC), this range was from 3.1% to 14.8%. In both CD and UC, there were significant trends in hemodynamic instability, serum white cell count, serum electrolytes and creatinine, and outcome measures length of stay and unplanned return to theater.

Patients having emergency surgery for IBD are not a single cohort when considering physiology, blood biochemistry, or most importantly, outcomes. Risk counseling and management should reflect this. Hemodynamic changes are subtle and may be missed in this cohort.

Thirty-day mortality is higher after urgent major lower extremity amputations compared to elective lower extremity amputations. This study aims to identify factors associated with urgent amputations and to examine their impact on perioperative outcomes and long-term mortality.

Patients undergoing major lower limb amputation from 2013 to 2020 in the Vascular Quality Initiative were included. Urgent amputation was defined as occurring within 72 hr of admission. Associations with sociodemographic characteristics, comorbidities, and outcomes including postoperative complication, inpatient death, and long-term survival were compared using univariable tests and multivariable logistic regression. Long-term survival between groups was compared using Kaplan-Meier analysis.

Of the 12,874 patients included, 4,850 (37.7%) had urgent and 8,024 (62.3%) had elective amputations. Non-White patients required urgent amputation more often than White patients (39.8% vs. 37.9%, P = 0.03). A higher proportion of Medicaid and self-pay patients presented urgently (Medicaid: 13.0% vs. 11.0%; self-pay: 3.4% vs. 2.5%, P < 0.001). Patients requiring urgent amputation were less often taking aspirin (55.6% vs. 60.1%, P < 0.001) or statin (62.2% vs. 67.2%, P < 0.001), had fewer prior revascularization procedures (41.0% vs. 48.8%, P < 0.001), and were of higher American Society of Anesthesiologists (ASA) class 4-5 (50.9% vs. 40.1%, P < 0.001). Urgent amputations were more commonly for uncontrolled infection (48.1% vs. 29.4%, P < 0.001) or acute limb ischemia (14.3% vs. 6.2%, P < 0.001). Postoperative complications were higher after urgent amputations (34.7% vs. 16.6%, P < 0.001), including need for return to operating room (23.8% vs. 8.4%, P < 0.001) and need for higher revision (15.2% vs. 4.5%, P < 0.001). Inpatient mortality was higher after urgent amputation (8.9% vs. 5.4%, P < 0.001). Multivariable analysis revealed non-White race, self-pay, homelessness, current smoking, ASA class 4-5, and amputations for uncontrolled infection or acute limb ischemia were associated with urgent status, whereas living in a nursing home or prior revascularization were protective. Furthermore, urgent amputation was associated with an increased odds of postoperative complication or death (odds ratio 1.86 [1.69-2.04], P < 0.001) as well as long-term mortality (odds ratio: 1.24 [1.13-1.35], P < 0.001). Kaplan-Meier analysis corroborated that elective status was associated with improvement of long-term survival.

Patients requiring urgent amputations are more often non-White, uninsured, and less frequently had prior revascularization procedures, revealing disparities in access to care. Urgency was associated with a higher postoperative complication rate, as well as increased long-term mortality. Efforts should be directed toward reducing these disparities to improve outcomes following amputation.

Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure used to alleviate portal hypertension in patients with decompensated liver cirrhosis. The weekend effect refers to a higher risk of adverse outcomes associated with procedures performed on weekends compared to weekdays. The goal of this study is to determine whether a weekend effect is evident in TIPS procedures.

The study identified patients who underwent TIPS procedures in the NIS database from 2015 to 2020. Patients who were admitted on the weekday or weekends were classified into two cohorts. Preoperative variables, including demographics, comorbidities, primary payer status, and hospital characteristics, were noted. Multivariable analysis was used to assess outcomes.

Compared to patients admitted on the weekdays, weekend patients had higher in-hospital mortality (12.87 % vs. 7.96 %, aOR = 1.62, 95 CI 1.32-1.00, p < 0.01), hepatic encephalopathy (33.24 % vs. 26.18 %, aOR = 1.41, 95 CI 1.23-1.63, p < 0.01), acute kidney injury (39.03 % vs. 28.36 %, aOR = 1.68, 95 CI 1.46-1.93, p < 0.01), and transfer out (15.91 % vs. 12.76 %, aOR=1.33, 95 CI 1.11-1.60, p < 0.01). It was also found that weekend patients had longer wait from admission to operation (3.83 ± 0.15 days vs 2.82 ± 0.07 days, p < 0.01), longer LOS (11.22 ± 0.33 days vs 8.38 ± 0.15 days, p < 0.01), and higher total hospital charge (219,973 ± 7,352 dollars vs 172,663 ± 3,183 dollars, p < 0.01).

Our research unveiled a significant relationship between weekend admission and a higher risk of mortality and morbidity post-TIPS procedure. Eliminating delays in treatment associated with the weekend effect may mitigate this gap to deliver consistent and high-quality care to all patients.

General anesthesia is common, but concerns regarding post-operative complications and mortality remain. No study has described the Danish patient population undergoing general anesthesia on a national level. The aim of this study was to describe the characteristics and outcomes of patients undergoing general anesthesia in Denmark.

This study was a registry-based observational cohort study of adult patients (≥18 years) undergoing general anesthesia in Denmark during 2020 and 2021. Data from nationwide registries covering patient characteristics, anesthesia and procedure information, and patient outcomes were combined. Descriptive statistics were used to present findings, both overall and in subgroups based on the American Society of Anesthesiologists (ASA) classification.

We identified 453,133 cases of general anesthesia in 328,951 unique patients. The median age was 57 years (quartiles: 41, 71), and 242,679 (54%) were females. Data on ASA classification were missing for less than 1% of the population, and ASA II was the most prevalent ASA classification (49%). Among cases of general anesthesia, 0.1% experienced a stroke, 0.2% had in-hospital cardiac arrest, and 3.9% had a stay in the intensive care unit within 30 days. Mortality at 30 days and 1 year were 1.8% and 6.3%, respectively, increasing with a higher ASA classification.

This study offers the first comprehensive overview of adult patients undergoing general anesthesia in Denmark. Post-anesthesia complications were few and increased with ASA classification.

The National Confidential Enquiry into Patient Outcome and Death (NCEPOD) reviewed the quality of care provided to adult patients undergoing surgery for Crohn's disease. The study reviewed elective, and emergency surgical pathways and the report highlighted clinical and organisational changes that should be made to improve patient care and outcomes.

In the emergency care of cancer patients, in addition to cancer-related factors, two aspects influence the outcome: (1) where the patient is treated and (2) who will perform the surgery. In Brazil, a significant proportion of patients with surgical oncological emergencies will be operated on in general hospitals by surgeons without training in oncological surgery.

The objective was to discuss quality indicators and propose the creation of an urgent oncological surgery advanced life support course.

Review of articles on the topic.

Generally, nonelective resections are associated with higher rates of morbidity and mortality, as well as lower rates of cancer-specific survival. In comparison to elective procedures, the reduced number of harvested lymph nodes and the higher rate of positive margins suggest a compromised degree of radicality in the emergency scenario.

Among modifiable factors is the training of the emergency surgeon. Enhancing the practice of oncological surgery in emergency settings constitutes a formidable undertaking that entails collaboration across various medical specialties and warrants endorsement and support from medical societies and educational institutions. It is time to establish a national registry encompassing oncological emergencies, develop quality indicators tailored to the national context, and foster the establishment of specialized training programs aimed at enhancing the proficiency of physicians serving in emergency services catering to cancer patients.

Although elective procedures have life-changing potential, all surgeries come with an inherent risk of reoperation. There is a gap in knowledge investigating the risk of reoperation across orthopaedics. We aimed to identify the elective orthopaedic procedures with the highest rate of unplanned reoperation and the reasons for these procedures having such high reoperation rates.

Patients in the NSQIP database were identified using CPT and ICD-10 codes. We isolated 612,815 orthopaedics procedures from 2018 to 2020 and identified the 10 CPT codes with the greatest rate of unplanned return to the operating room. For each index procedure, we identified the ICD-10 codes for the reoperation procedure and categorized them into infection, mechanical failure, fracture, wound disruption, hematoma or seroma, nerve pathology, other, and unspecified.

Below knee amputation (BKA) (CPT 27880) had the highest reoperation rate of 6.92% (37 of 535 patients). Posterior-approach thoracic (5.86%) or cervical (4.14%) arthrodesis and cervical laminectomy (3.85%), revision total hip arthroplasty (5.23%), conversion to total hip arthroplasty (4.33%), and revision shoulder arthroplasty (4.22%) were among the remaining highest reoperation rates. The overall leading causes of reoperation were infection (30.1%), mechanical failure (21.1%), and hematoma or seroma (9.4%) for the 10 procedures with the highest reoperation rates.

This study successfully identified the elective orthopaedic procedures with the highest 30-day return to OR rates. These include BKA, posterior thoracic and cervical spinal arthrodesis, revision hip arthroplasty, revision total shoulder arthroplasty, and cervical laminectomy. With this data, we can identify areas across orthopaedics in which revising protocols may improve patient outcomes and limit the burden of reoperations on patients and the healthcare system. Future studies should focus on the long-term physical and financial impact that these reoperations may have on patients and hospital systems.

IV.

Kentucky was among the first to adopt Medicaid expansion, resulting in reducing uninsured rates from 14.3% to 6.4%. We hypothesize that Medicaid expansion resulted in increased elective healthcare utilization and reductions in emergency treatments by patients suffering Inflammatory Bowel Disease (IBD).

The Hospital Inpatient Discharge and Outpatient Services Database (HIDOSD) identified all encounters related to IBD from 2009 to 2020 in Kentucky. Several demographic variables were compared in pre- and post-Medicaid expansion adoption.

Our study analyzed 3386 pre-expansion and 24,255 post-expansion encounters for IBD patients. Results showed that hospitalization rates dropped (47.7%-8.4%), outpatient visits increased (52.3%-91.6%) and Emergency visits decreased (36.7%-11.4%). Admission following a clinical referral similarly increased with a corresponding drop in emergency room admissions. Hospital costs and lengths of stay also dropped following Medicaid expansion.

In the IBD population, Medicaid expansion improved access to preventative care, reduced hospital costs by decreasing emergency care, and increased elective care pathways.

Current guidelines for sigmoid volvulus recommend endoscopy as a first line of treatment for decompression, followed by colectomy as early as possible. Timing of the latter varies greatly. This study compared early (≤2 days) versus delayed (>2 days) sigmoid colectomy.

2016-2019 NRD database was queried to identify patients aged ≥65 years admitted for sigmoid volvulus who underwent sequential endoscopic decompression and sigmoid colectomy. Outcomes included mortality, complications, hospital length of stay, readmissions, and hospital costs.

842 patients were included, of which 409 (48.6 ​%) underwent delayed sigmoid colectomy. Delayed sigmoid colectomy was associated with reduced cardiac complications (1.1 ​% vs 0.0 ​%, p ​= ​0.045), reduced ostomy rate (38.3 ​% vs 29.4 ​%, p ​= ​0.013), an increased overall length of stay (12 days vs 8 days, p ​< ​0.001) and increased overall costs (27,764 dollar vs. 24,472 dollar, p ​< ​0.001).

In geriatric patient with sigmoid volvulus, delayed surgical resection after decompression is associated with reduced cardiac complications and reduced ostomy rate, while increasing overall hospital length of stay and costs.

Background Postoperative complications (POC) are undesirable consequences of surgery and are a major area of concern adversely affecting the quality of surgical care and patient safety. Emergency surgery has been observed to have a higher incidence of different POC. The analysis of POC is of great importance due to their impact on the quality of life of patients and because they have become an indicator to measure the quality of hospital services. Objective This study aimed to describe the POC of emergency surgeries in patients from the general surgery department of a referral hospital in eastern Venezuela. Methodology A cross-sectional retrospective study was conducted, including patients undergoing emergency surgery at "Dr. Luis Razetti" University Hospital, Barcelona, Venezuela, between November 2022 and May 2023. Results Medical records of 178 patients were analyzed. Most were male (53.7%), with an average age of 34.98 and a standard deviation of 18.2 years. POC was registered in 28 (15.7%) patients, with surgical site infection being the most common in 21 (39.62%) patients. Those over 65 years old (21.4% vs. 6.4%, p=0.013), patients with a history of hypertension (25% vs. 6.3%, p=0.002), hypoalbuminemia (100% vs. 43.8%, p=0.027), diagnosed with peritonitis due to hollow viscus perforation (21.4% vs. 6%, p=0.007), trauma (25% vs. 9.3%, p=0.018), and those with a midline incision (75% vs. 31.3%, p<0.001) had a higher frequency of POC. There was a mortality rate of 2.8% with no significant difference based on the development of POC. Conclusion POC represents a significant cause of morbidity and mortality in patients undergoing emergency surgeries. The studied sample showed a similar frequency of POC compared to previous reports but with lower mortality. Complications were associated with higher frequencies of hypertension, midline approach, hypoalbuminemia, and emergency surgery for peritonitis due to hollow viscus perforation and trauma.
