Randomized control trial on impact of clinical pharmacist led interventions on antibiotic stewardship program in children 0 to 18 years age in a tertiary care hospital in southern India

Abstract

A prospective randomized controlled interventional study was conducted at a quaternary care multispecialty hospital in South India with the primary objective of identifying opportunities to improve antibiotic prescribing patterns in neonates, children, and adolescents. The hospital has a robust clinical pharmacist program wherein antibiotic prescriptions were checked for appropriateness of antibiotic dose, route, formulation, duration of therapy, and IV to oral switch. These characteristics of antibiotic use were therefore similar in the 75 children in the control and 75 in the intervention group. The additional clinical pharmacist interventions analyzed in this study included checking if a provisional diagnosis had been made before initiating antibiotics, ensuring that appropriate cultures were sent before starting antibiotics, time taken to optimize antibiotic therapy in accordance to the culture sensitivity report and whether the indication for antibiotics use was as per Indian Acdemy of Pediatrics (IAP) Drug Formulary recommendations. The main outcomes were that all these parameters except the first (all children had a clinical diagnosis before initiating antibiotic/s) were better in the intervention group and there was a significant reduction in the total antibiotic days, an increase in antibiotic-free days, and an improvement in the appropriateness of duration of antibiotic therapy and frequency of the antibiotic dosing. However, since the incidence of severe sepsis was higher in the intervention group, broad-spectrum and restricted antibiotics were used, and thus treatment costs were higher in this group. The results indicate that despite already existing clinical pharmacist interventions, additional ones could further improve antibiotic prescription accuracy significantly; and re-emphasized the need to employ trained pediatric general and subspecialty clinical pharmacists in sufficient numbers to implement a successful pediatric antibiotic stewardship program in a hospital.
