Pharmacists often perform medication reconciliation at hospital admission and discharge to prevent medication errors. This meta-analysis examined the efficacy of pharmacist-led medication reconciliation across 18 trials that included more than 6000 patients. Researchers found that pharmacist-led interventions reduced medication discrepancies but did not significantly affect adverse medication events or health care utilization. However, a recent large trial of pharmacist-led medication reconciliation with positive results was excluded from this meta-analysis.
