Core Tip
Core Tip: Adverse event (AE) grading is useful only when paired with robust documentation and a clear review pathway. A practical model is to track AEs for benchmarking while retaining an incident or near-miss stream for prevention signals, and to measure diagnostic delay and procedural appropriateness with separate indicators rather than forcing them into AE registries.
