Impact of pharmacist medication review for paediatric patients: an observational study.

BACKGROUND: Paediatric patients are at high risk of medication errors and adverse drug events due to complex medical care. OBJECTIVE: To assess the impact of pharmacist medication review for paediatric patients. SETTING: A single-centre prospective observational study was performed over 33 months, from February 2018 to October 2020 in a French Hospital. METHOD: Clinical pharmacists provided medication counselling at a hospital and conducted telephone follow-ups between 3 and 7 days after discharge of paediatric patients with chronic diseases for whom treatment was introduced or modified during hospitalisation or hospital consultations. MAIN OUTCOME MEASURES: The incidence of drug-related problems (DRPs), the number and type of pharmacist intervention and paediatrician acceptance rates were assessed. Parents' understanding and drug-related needs were compared before and after medication review. Time to outpatient treatment and patient satisfaction were determined. Statistical analyses were performed in Excel. RESULTS: In total, 195 paediatric patients were included. Pharmacists identified 65 interventions, 95% of which were accepted. The most frequent DRPs included inappropriate drug administration (32.3%), herb-drug interactions (24.6%) and dose selection (17%). Parents' knowledge increased by 28% from baseline after pharmacist's medication counselling. Parents' drug-related needs concerning administration and side effects decreased by 67% and 49%, respectively, following the pharmacist's medication counselling. Most (75%) of the patients were able to get their treatment immediately after discharge. CONCLUSION: Clinical pharmacists can improve medication safety for children during the discharge process or consultations, by reducing prescription errors, optimising administration, counselling patients or parents and helping to ensure care continuity.
