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

The use of antibiotics is the main factor of microbial resistance.

To determine the consumption of antibiotics in health care institutions in Santiago de Cali between 2013 and 2020.

The methodology of the Defined Daily Dose per 100 beddays 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.

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.

The system provided tools for prospective surveillance that showed the need for intervention in institutions.
