2288. Role of Β Lactam-Β Lactamase Inhibitors in Indian Tertiary Care Hospitals: Results from a Nationwide Survey

Abstract

BackgroundBroad-spectrum antibiotics, particularly third-generation cephalosporins, are routinely used in the treatment of nosocomial infections. The emergence of Extended Spectrum Β-Lactamase (ESBL)-producing pathogens in Indian tertiary care hospitals warrants the need to reassess β-lactam–β-lactamase inhibitors (BL-BLIs) as better alternative treatments.MethodsAn online survey was conducted by Pfizer India to understand the usage of BL-BLIs across Indian hospitals. The survey was administered to 334 clinicians across multiple specialties out of which 195 were from tertiary care hospitals. Results were analyzed using MS-Excel statistical tools.ResultsOne-hundred ninety-five (195) clinicians from tertiary care hospitals completed the survey. About 78% of HCPs revealed the resistance to third-generation cephalosporins (e.g., ceftriaxone, ceftazidime) to be between 10–60% in their clinical settings. BL-BLIs were mostly preferred for treatment based on hospital antibiograms (64%) and used as first-line options for hospitalized adults with mild-moderate severe infections caused by ESBL-producing organisms (71%) and in mild-moderate infections caused by susceptible Gram-negative bacteria such as Enterobacteriaceae (54%). The average duration of IV BL-BLI treatment was 5–7 days (66%). The HCPs considerations while choosing BL-BLIs were mainly based on anti-microbial spectrum (81%), and rationality of BL/BLI combination (63%) and clinical experience with the BL-BLI molecule (63%). Cefoperazone-Sulbactam (CS) and Piperacillin–tazobactam (PT) were most commonly prescribed BL-BLIs and HCPs preferred the latter for pneumonia (67%), skin and soft-tissue infections (57%), bloodstream infections (67%) and cancer-associated febrile neutropenia (64%); while they preferred former for urinary tract infections (64%). CS and PT were preferred for intra-abdominal infections (57% and 64% respectively) and post-surgical infections (56% and 53% respectively).ConclusionCS and PT were the most commonly prescribed BL-BLIs probably due to their wide antimicrobial spectrum, rationality of the BL/BLI combination and the clinical experience with the molecules. BL-BLIs are still a mainstay of treatment for infections due to ESBL producing organisms. Disclosures All authors: No reported disclosures.
