Medication errors and adverse drug events in pediatric inpatients

Area of Science:

• Pediatric pharmacology
• Patient safety research
• Epidemiology of iatrogenic injuries

Background:

• Iatrogenic injuries, including medication errors, pose a significant challenge in hospitalized populations.
• Limited epidemiological data exist on medication errors specifically within pediatric inpatient settings.

Purpose of the Study:

• To determine the incidence of medication errors, adverse drug events (ADEs), and potential ADEs in pediatric inpatients.
• To compare pediatric ADE rates with previously documented adult rates.
• To identify common types of medication errors and assess the potential effectiveness of prevention strategies.

Main Methods:

• A prospective cohort study involving 1120 patients across two academic institutions over six weeks.
• Data collection included clinical staff reports, medication order sheets, administration records, and patient charts.
• Identification of medication errors, potential ADEs, and ADEs was conducted through rigorous review processes.

Main Results:

• A total of 616 medication errors (5.7%), 115 potential ADEs (1.1%), and 26 ADEs (0.24%) were identified from 10,778 medication orders.
• The rate of potential ADEs in pediatric patients was three times higher than in adults, particularly in neonatal intensive care units.
• Most potential ADEs stemmed from the drug ordering stage, involving incorrect dosing, anti-infective drugs, and intravenous medications.

Conclusions:

• Medication errors are prevalent in pediatric inpatient environments.
• The high rate of potential ADEs underscores the urgent need for enhanced safety measures and interventions.
• Computerized physician order entry and ward-based pharmacists show significant potential in preventing ADEs.
