The feasibility of using of a comprehensive unit-based safety program (CUSP) for improving antimicrobial stewardship at a tertiary care hospital in national capital region of India: A prospective quasi experimental study

Abstract

PurposeTo examine the feasibility of Comprehensive Unit-based Safety Program (CUSP) as a strategy tool to improve antibiotic stewardship in low and middle income countries (LMIC) in resource limited setting. The primary outcome measure is identification of inappropriate prescriptions. The secondary outcome parameters are App adoption trends and antimicrobial prescription pattern and practices. Material and methodsA prospective quasi-experimental design was used to operationalizing the CUSP intervention. The project considered the data of 482 patients from two mixed Medical ICUs admitted during June 2019 to April 2020. The information was collected on antimicrobials prescription pattern and practices for identification of inappropriate use as well as app adoption trend with respect to Electronic Medical Record (EMR) Orders Placed, Clinical Notes and Checklist Filled. The intervention in the study comprised of development of an antibiotic monitoring stewardship (AMS) data collection app for ease of use and for Clinical Decision Support System (CDSS) to identify the cases of inappropriate use of antibiotics. ResultsData of patients was reviewed to create algorithms for empirical and directed antibiotic therapy as well as to create a CDSS app. Out of 793 prescriptions initially during July–September 2019, 19 (2.4%) were inappropriate antimicrobial prescription. The continuous monitoring of antimicrobial prescription helped in reducing the irrational use and bring it to level zero at the end. ConclusionIt requires commitment from the management, and seamless communication within Clinical, Microbiology, Pharmacology and data management teams to create and run a successful CUSP program towards Antimicrobial Resistance. Tools such as the CDSS can smoothen the process.
