Abstract
BACKGROUND
Empathetic psychological care improves mood and enhances the quality of life in critically ill patients.
AIM
To study the impact of combining 222-nm ultraviolet (UV) disinfection with empathetic psychological care on emotional states, nosocomial infection rates, and quality of life in critically ill patients.
METHODS
A total of 202 critically ill patients admitted to Beijing Ditan Hospital (December 2023 to May 2024) were randomly assigned to control (Ctrl, n = 101) or observation groups (Obs, n = 101). The Ctrl group received 222-nm UV disinfection and routine care, while the Obs group received 222-nm UV disinfection with empathetic psychological care. Emotional states [Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS)], hospital infection rates, quality of life (36-Item Short Form Health Survey), and patient satisfaction were evaluated.
RESULTS
At baseline, there were no significant differences in SAS and SDS scores between the groups (P > 0.05). Following care, both groups demonstrated reductions in SAS and SDS scores, with the Obs group exhibiting a significantly greater reduction (P < 0.05). The Obs group also experienced a significantly lower overall hospital infection rate (P < 0.05). Similarly, while baseline 36-Item Short Form Health Survey scores did not differ significantly between the groups (P > 0.05), post-care scores improved in both groups, with a greater improvement observed in the Obs group (P < 0.05). Additionally, the Obs group reported higher patient satisfaction ratings (P < 0.05).
CONCLUSION
The combination of 222-nm UV disinfection and empathetic psychological care improves emotional states, reduces hospital infection rates, enhances the quality of life, and increases patient satisfaction among critically ill patients.
Core Tip: In the intensive care unit, effective disinfection and psychological care are crucial for critically ill patients. Enhancing disinfection efficacy not only reduces the risk of hospital-acquired infections, safeguarding patients from infectious diseases, but also boosts their trust in the healthcare environment. By providing timely psychological support and intervention, it helps patients better cope with the stress and anxiety brought on by their illnesses, strengthening their psychological resilience. This comprehensive approach to care not only elevates the quality of life for patients but also facilitates their recovery process, ultimately achieving better therapeutic outcomes and patient satisfaction.
