Monitoring of antimicrobial stewardship implementation in Swiss hospitals: results from a national survey
Abstract
AIM: Antimicrobial stewardship (AMS) is essential to containing antimicrobial resistance. Under the Swiss Strategy on Antibiotic Resistance (StAR), a nationwide survey was conducted to assess antimicrobial stewardship implementation in acute care hospitals and inform future national stewardship strategies.
METHODS
A total of 136 acute care hospitals in Switzerland were invited to complete a questionnaire adapted from a validated Dutch tool and modified for the Swiss context. The questionnaire gathered information on whether a formal antimicrobial stewardship programme was present (primary outcome), institutional characteristics, as well as key antimicrobial stewardship activities (secondary outcomes) such as guideline implementation, education, raising awareness, prescription restrictions, and audits. Descriptive statistics and analyses compared the implementation of antimicrobial stewardship activities by the presence of a formal antimicrobial stewardship programme.
RESULTS
Sixty-nine hospitals completed the survey (response rate: 51%); these hospitals represent 67% of all patient discharges in Switzerland in 2023. Although 86% reported engaging in at least one antimicrobial stewardship activity, only 47% had a formal antimicrobial stewardship programme (primary outcome). Most institutions reported providing infectious diseases specialist consult services (93%), clinical pharmacy support (84%), and microbiology advice (78%). Treatment guidelines (90%) and monitoring…
