Impact of pharmacist intervention in antibiotic stewardship programmes for critically ill neonates: A systematic review and meta-analysis

Abstract

What is known and objective: Antibiotic stewardship programmes (ASPs) are introduced to ensure effective antibiotic use. Pharmacists can be involved in ASPs to facilitate the appropriate antibiotic use. Prolonged use of antibiotics causes adverse events in critically ill neonates. Hence, this systematic review and meta-analysis was aimed at investigating pharmacists' functions in ASPs in critically ill neonates and the effect of ASP implementation on antibiotic use.

Methods: A comprehensive search of PubMed/Medline, Embase, and Cochrane Library databases until January 2021 was conducted and studies that reported the functions of pharmacists in ASPs for critically ill neonates and the results of ASP implementation were included in this review. All processes were performed by two reviewers independently, and any discordance between the two was resolved by discussion.

Results and discussion: In all, 19 studies were included in this review. Pharmacists were found to have various functions in ASPs, such as participating in the development of antibiotic use guidelines, auditing antibiotic prescriptions, participating in multidisciplinary ward rounds, educating other ASP team members, checking blood culture or laboratory data, and monitoring antibiotic use. A meta-analysis revealed that ASP implementation in critically ill neonates was significantly associated with a 23% reduction in the overall antibiotic use rate (ratio of means: 0.77, 95% confidence interval: 0.69-0.87, p < 0.001). Moreover, the overall duration of antibiotic therapy significantly reduced by 15% with ASP implementation (ratio of means: 0.85, 95% confidence interval: 0.78-0.91, p < 0.001).

What is new and conclusion: The implementation of ASPs involving pharmacists, especially in critically ill neonates, was associated with the reduced use and duration of antibiotic treatment. Thus, pharmacists played a key role in ASPs in critically ill neonates.
