Background. Improper utilization of antimicrobials has impacted clinical outcomes in patient care and economical costs. Pediatric antimicrobial stewardship (Ped ASP) lowers healthcare costs by promoting efficient and judicious use of antimicrobials which improves patient outcomes and amends resource utilization. The objective of this study is to evaluate the cost-effectiveness of a Ped ASP in a non-freestanding children's hospital within an adult-centered tertiary hospital. Methods. We conducted a cost-effective analysis of our Ped ASP within a 685-bed, adult-centered medical center. Impacted by the COVID pandemic, the pediatric services reduced from 21 to 14 beds with 10 general pediatrics (PED) and 4 pediatric intensive care (PICU) beds. Our Ped ASP activities include thrice-weekly chart reviews followed by handshake rounds and quarterly reviews of documented interventions. The preset values of antimicrobial-specific interventions in the Electronic Medical Record system were utilized. An average cost savings of $732 (range: $2.5 - $2,640) per patient as determined by previous studies was used to calculate the annual cost savings. Results. During years 2020 to 2021, antibiotic days of therapy per 1000 patient days (DOT) decreased from 290.4 to 100.2 in PED but increased from 433 to 569.1 in PICU. The ratio of broad to narrow-spectrum antibiotics decreased from 0.46 to 0.20 in PED and 0.69 to 0.63 in PICU. In 2020, 286 reviews were completed of 155 patients which projected an average cost savings of $113,460 (range: $387.5 - $409,200). In 2021, 256 reviews of 116 patients projected an average cost savings of $84,912 (range $290 - $306,240). An estimated overall annual cost-savings was $99,186. The total number of ASP-specific interventions in 2020 and 2021 were 172 and 146 with projected pharmacy intervention values of $26,354 and $19,170 respectively. Conclusion. Our Ped ASP effectively reduces the usage of broad-spectrum antibiotics in both PED and PICU demonstrating cost savings. Implementing antibiotic time-out reports on specific broad-spectrum antibiotics based on local susceptibility data may further enhance the safety and appropriateness of antimicrobial therapy.
