Key result
The AT-HARM10 tool successfully assessed 97.3% of emergency department visits in older patients, demonstrating substantial interrater reliability (Cohen's kappa 0.70) for identifying possible drug-related visits.
Why the study?
AT-HARM10 identifies possible drug-related hospital admissions, but it was unclear whether it can also be applied to emergency department visits.
Is the AT-HARM10 tool applicable and reliable for identifying drug-related emergency department visits in older patients?

The AT-HARM10 tool is applicable and reliable for identifying possible drug-related emergency department visits in older patients.
Kempen et al. (2022) conducted an observational in Emergency department visits (n=113). AT-HARM10 assessment tool was evaluated on Percentage of successfully assessed visits and interrater reliability (Kappa 0.70). The AT-HARM10 tool successfully assessed 97.3% of emergency department visits in older patients, demonstrating substantial interrater reliability (Cohen's kappa 0.70) for identifying possible drug-related visits.
