Sumario: | BACKGROUND: Inappropriate use of antimicrobials is one of the core contributors to antimicrobial resistance. While hospitals create high selection pressures on bacteria due to the high quantity and broader spectrum of antibiotics used, information on antimicrobial use at the patient level in the Caribbean is sparse. In response, PAHO implemented a standardized WHO methodology to engage national leaderships, build local capacity, and facilitate the use of data to inform antimicrobial stewardship programs (ASP) in the Caribbean. METHODS: Point prevalence surveys (PPS) were performed in four acute care hospitals in Barbados, Guyana and Saint Lucia between June and July 2018. Medical records of all inpatients were reviewed to collect information on antibiotic use, indications and use of laboratory services (Figure 1). A hospital questionnaire was used to assess hospital infrastructure, policy and practices, and monitoring and feedback systems (Figure 2). Training on PPS methods and electronic data collection tool in REDCap™ were provided to build local capacity and identify potential ASP leaderships. A standardized data validation, analysis and reporting system was built in R to streamline the process. Results and recommendations were disseminated to national authorities and stakeholders to support hospital and national decision-making and training for healthcare providers (Figure 3). RESULTS: A total of 60 physicians, nurses, pharmacists, laboratory technicians, and infection control specialists were trained and participated in the PPS. The survey collected records of 816 patients in which 442 (54%) were females and 374 (46%) were males. In total, 356 (44%) patients received 551 antibiotics. Overall, 300 (75%) of 398 indications for antibiotic use were treatment and 72 (18%) were prophylaxis. A higher use of parenteral antibiotics (79%) was observed compared with oral antibiotics (21%). Antibiotic prescribing patterns differed across hospitals. The most commonly used antibiotics were metronidazole (12%) and amoxicillin/clavulanate (11%). CONCLUSION: The PPS method provided a feasible and effective way to collect baseline data and identify target areas for interventions. Engaging national leaderships and building local capacity offered a sustainable way in optimizing antimicrobial use in resource-limited settings.
