ABSTRACT
Background. Antibiotic stewardship programs (ASP) are relatively new in Mexico. It was until May 2018 that it was established as a public health policy in the country. Few hospitals have acknowledged the mandate and started an ASP despite the efforts. Besides, little has been done to evaluate the efficacy of the program in terms of antibiotic expenditure and the incidence of associated infections. Therefore, the main objective was to evaluate antibiotic expenditure before and after the ASP in a third-level hospital in Mexico. As a secondary analysis, the relationship with Clostridioides difficile infections was explored. Methods. This is a retrospective and descriptive study from January 2017 to February 2020 (pre-COVID-19 pandemic). First, the mean antibiotic expenditure (adjusting for DDD/patient days-costs in USD) was evaluated before and after (June 2018 as the first month of implementation) the ASP. Statistical difference of the means was evaluated. It was also performed an exploratory analysis between the prescription of Clindamycin and Levofloxacin with the number of cases and deaths related to C. difficile infection. Results. The average antibiotic expenditure before ASP was US$13,468 +/- 3,267, and US$8,193 +/- 2,574 (p< 0.001) after. Graph 1 presents the changes in trend. Specifically, caspofungin, ciprofloxacin, clindamycin, fluconazole, levofloxacin, linezolid, piperacillin/tazobactam, and tigecycline showed statistically significant reduction after June 2018. Graph 2 displays the descriptive relationship between the prescription of levofloxacin and clindamycin, the cases of C. difficile infection, and the elimination of all associated mortality. Graph 1.

Relationship between monthly consumption of clindamycin and levofloxacin and the number of cases/deaths secondary to Clostridioides difficile infections, before and after ASP. Conclusion. The ASP has significantly reduced the antibiotic expenditure in the hospital. Besides reducing the prescription of associated antibiotics, a possible reduction in C. difficile infections and associated deaths were observed.
