To the Editor: Around 75% of admitted children receive antibiotics in India, mostly unnecessarily or inappropriate, producing antibiotic resistance [1]. Antibiotic stewardship program (ASP), is a multidisciplinary programme that helps rationalize and restrict use of antibiotics [2]. Data on pediatric focused ASPs are rare and necessary because of unique indication, dosing, and vulnerability for lifetime resistance [3, 4].

In this quasi-experimental study, we evaluated the efficacy of an intervention, wherein the pediatricians had to fill a justification form before starting antibiotics.

Children who were admitted to the hospital from June 2018 to March 2019 were selected by systematic random sampling and enrolled in study as postintervention group. Children who were admitted to the pediatric ward previous year, during the same time period, i.e., June 2017 to March 2018 were taken as preintervention group.

Pediatricians had to fill the justification form within 24 h of starting antibiotic after cultures, that was notified within 48 to 72 h. If antibiotics had to be continued, justification should be written in the form, and reviewed on day 7 or at discharge. Any decision to continue antibiotic further needed justification.

Similar pattern of illness was seen in both the groups. Of the post-intervention group, 55% were started on antibiotics as against 82.4% in the preintervention group (p value < 0.001). De-escalation was done in 17.1% and 1.9% in the post- & preintervention group (p value < 0.001). Duration of antibotics therapy was significantly lower in the postintervention group (p value < 0.001).

Disease spectrum among the groups being comparable, the reduction in initial usage and de-escalation of antibiotics are attributed to the awareness created by the justification form. The written commitment was probably the most important factor in reducing antibiotic usage.

We conclude that implementation of antibiotic justification form is a simple and cost-effective intervention with vast implications in any clinical setup, thereby reducing antibiotic resistance.
