Impact of Antimicrobial Stewardship on Physician Practice in a Geriatric Facility.

BACKGROUND: There is a paucity of literature describing the implementation of antimicrobial stewardship programs (ASPs) in long-term care (LTC) facilities. The current study evaluated the impact of an ASP that was implemented across a geriatric facility, which included an inpatient specialty hospital and an LTC facility. The program included prospective audits with feedback, multidisciplinary education, information technology interventions, and guideline development. OBJECTIVE: To investigate the impact of the ASP on physicians' prescribing practices in this geriatric facility. METHODS: Utilization data for antibiotics commonly used to treat urinary tract infections were retrieved for the period September 1, 2011, to August 31, 2013. The study examined whether there were significant changes in overall antibiotic use, ciprofloxacin use, and physician prescribing behaviour after program implementation in September 2012. RESULTS: There was no significant change in the total number of antibiotic prescriptions for urinary tract infections in the hospital or the LTC facility after ASP implementation. Significant reductions were seen in the average days of therapy initially prescribed and the actual days of therapy after ASP implementation in the LTC facility but not the hospital. Across both facilities, significant reductions were seen in the number of ciprofloxacin prescriptions. CONCLUSIONS: The current study showed that an ASP can affect physicians' antibiotic prescribing behaviour and antibiotic usage in an LTC environment.

Il n'existe que très peu de documentation qui porte sur la mise en œuvre de programmes de gérance des antimicrobiens dans les établissements de soins de longue durée. La présente étude a évalué l'effet d'un programme de gérance des antimicrobiens mis en œuvre dans l'ensemble d'un centre gériatrique, qui comprenait un hôpital spécialisé et un établissement de soins de longue durée. Le programme comprenait des audits prospectifs accompagnés de rétroaction, des séances de formation multidisciplinaire, des interventions s'appuyant sur les technologies de l'information et l'élaboration de lignes directrices.
