Optimizing Medication Safety Review and Adverse Drug Events: A Quality Improvement Study

Children are susceptible to adverse drug events, especially those related to high-alert and nephrotoxic medications. This study aimed to reduce the number of days in between reported medication safety events related to high-alert and nephrotoxic medications by 5% over a 28-month period.

This single-center quality improvement study at an urban academic institution occurred across 1 acute care and 3 intensive care units. Interventions focused on increased emphasis on these medications (targeted medication list, rounding script modifications, and provider education), review of medication orders, and rounding audits. Outcomes were the number of days in between events for high-alert and nephrotoxic medications (manual review of events from the event reporting system). Process measures included bundles related to high-alert and nephrotoxic medications (eg, knowledge and discussion of elements) observed during rounds. Metrics were analyzed using statistical process control G charts and run charts.

The number of days in between events related to high-alert medications decreased by 10 days; a centerline shift was observed. No centerline shifts were noted for nephrotoxic medications. Special cause variation was noted with more days in between events in the final year of the study period for both high-alert and nephrotoxic medications. Mean process compliance for the high-alert bundle was 90% (monthly range, 67%-100%) and 76% (monthly range, 25%-100%) for the nephrotoxic bundle.

Time in between high-alert medication event rates increased; process compliance varied but was unchanged overall. Future work should focus on continued tracking of metrics and incorporating additional interventions, including electronic health record changes.
