Purpose: This study analyzed medication-related patient safety incidents reported to the Korea Patient Safety Reporting and Learning System (KOPS) from 2020 to 2024 to examine differences in the occurrence of harm by patient age, reporter, hospital type, time of daytime (incident time), and handover time windows, and to identify predictors of harm. Methods: A retrospective analysis was conducted using 8,602 medication-related incident reports with complete key variables extracted from 36,281 KOPS reports. Data were analyzed using descriptive statistics, chi-square tests, and logistic regression. Time of daytime (incident time) was categorized as Daytime (08:00~16:00), Eveningtime (16:00~22:00), Night-time (22:00~08:00). Handover time windows included 06:00~08:00, 14:00~16:00, and 22:00~24:00. Results: Harm occurred in 0.7% of incidents. Patients aged≥80 years had significantly higher odds of harm (OR=4.26, p<.001) compared to those aged 20~59 years. Incidents reported by patient safety officers were less likely to result in harm than those reported by healthcare workers (OR=0.08, p<.001). Although most incidents were reported during daytime (57.6%), time of daytime(incident time) and handover time windows (23.8%) were not significant predictors of harm in multivariable analysis. Conclusion: Harm occurrence was more strongly associated with patient age and reporter characteristics than with the timing of incidents. These findings highlight the need to strengthen medication safety for older adults and promote a proactive reporting culture to improve patient safety.
