Methods used to identify and classify medication-related admissions and readmissions to hospitals: A systematic review

A range of methodologies exists for identifying medication-related hospital admissions, but few are both validated and feasible for clinical use. AT-HARM10 was the only tool meeting both criteria, making it the most suitable option for real-time application in clinical settings. These findings underscore the need for standardized, validated tools that are practical for routine use to improve detection and enable targeted interventions. Future research should prioritize validation across diverse populations to improve generalizability and support widespread implementation.
