Antibiotic consumption surveillance in 10 health institutions between 2013 and 2020 in Colombia

Abstract

Background: The use of antibiotics is the main factor of microbial resistance. Aim: To determine the consumption of antibiotics in health care institutions in Santiago de Cali between 2013 and 2020. Methods: The methodology of the Defined Daily Dose per 100 bed-days was employed. Institutions that had at least 9 annual reports and that the report is greater than 95% were defined as inclusion criteria. In this case, 10 institutions were included. Results: Consumption in Intensive Care Units (ICU) was higher than in other units. Ceftriaxone and imipenem were more consumed in units other than ICU, whereas meropenem, piperacillin/tazobactam and vancomycin were more consumed in the ICU. In units other than ICU, two institutions increased the consumption of ceftriaxone, ciprofloxacin and piperacillin/tazobactam and one the consumption of vancomycin, whereas in the ICU, one institution increased the consumption of piperacillin/tazobactam. The endemic range identified that vancomycin located itself in the epidemic zone in one institution. Conclusion: The system provided tools for prospective surveillance that showed the need for intervention in institutions.
