Core Outcome Measures in Effectiveness Trials

Interventions to Improve Antimicrobial Stewardship for Older People in Care Homes: A Systematic Review

General Information

Abstract:
BACKGROUND: Inappropriate antimicrobial prescribing has been reported in care homes. This may result in serious drug-related adverse events, Clostridium difficile colonization, and the development of antimicrobial resistance among care home residents. Interventions to improve antibiotic prescribing in nursing homes have been reported through clinical trials, but whether antifungal and antiviral prescribing and residential homes have been considered, or how outcomes were measured and reported in such interventions, remains unclear. OBJECTIVES: Our aims were to evaluate the effect of interventions to improve antimicrobial stewardship in care homes and to report the outcomes used in these trials. METHODS: We searched 11 electronic databases and five trial registries for studies published until 30 November 2018. Inclusion criteria for the review were randomized controlled trials, targeting care home residents and healthcare professionals, providing interventions to improve antimicrobial prescribing compared with usual care or other interventions. The Cochrane tools for assessing risk of bias were used for quality assessment. A narrative approach was taken because of heterogeneity across the studies. RESULTS: Five studies met the inclusion criteria. The studies varied in terms of types of infection, key targets, delivery of interventions, and reported outcomes. In total, 27 outcomes were reported across the studies, with seven not prespecified in the methods. The interventions had little impact on adherence to guidelines and prevalence of antimicrobial prescribing; they appeared to decrease total antimicrobial consumption but were unlikely to have affected overall hospital admissions and mortality. The overall quality of evidence was low because the risk of bias was high across the studies. CONCLUSION: The interventions had limited effect on improving antimicrobial prescribing but did not appear to cause harm to care home residents. The low quality of evidence and heterogeneity in outcome measurement suggest the need for future well-designed studies and the development of a core outcome set to best evaluate the effectiveness of antimicrobial stewardship in care homes.
