ANTIMICROBIAL STEWARDSHIP & HEALTHCARE EPIDEMIOLOGY, sa.1, 2024 (ESCI)
Objective: This study aims to assess the impact of hospital-specific guidelines on the optimal utilization of carbapenems and to examine their effects on patient outcomes. Design: Quasi-experimental study. Setting: Tertiary care hospital in Turkey where infectious diseases (IDs) consultation and antibiotic approval are mandatory for carbapenem use. Participants: All inpatients >= 18 years of age who received a carbapenem for at least 24 hours during the study periods were enrolled. Intervention: Hospital-specific treatment guidelines were introduced in April 2019. The control group was the year 2018, when there were no guidelines (pre-GP). The year 2020 was analyzed as the intervention period (post-GP). Results: A total of 678 patients were analyzed, 326 in the pre-GP period and 352 in the post-GP period. Following guideline implementation, there was a significant increase in appropriate carbapenem use (49.1% in pre-GP vs 71.9% in post-GP, P < .001). The duration of carbapenem use decreased significantly (P = .019). However, there was no significant change in the incidence of new infection episodes within the subsequent 30 days (27.6% in pre-GP vs 28.3% in post-GP), or in the length of hospitalization [median (25%-75%) = 28 (16-46) in pre-GP, 28 (15-47.5) in post-GP, P = .678]. Mortality rates were similar at day 7 post-GP (1.7%) compared to pre-GP (0.03%) (P = .125). Conclusions: The implementation of guidelines increased the appropriate utilization of carbapenems, without resulting in extended hospital stays or recurrent episodes. Despite an increased number of patients admitted to the ICU during the latter period, infection-related mortality rates remained comparable.
