    Abstract:
    OBJECTIVES: To evaluate the impact of 'Resident Antimicrobial Management Plan' (RAMP), a novel antimicrobial stewardship tool on systemic antibiotic use for treatment of infection in nursing homes (NHs). METHODS: A pilot cluster randomized control study was conducted in 30 NHs in London. Pre-intervention, we collected point prevalence data on antimicrobial use on three occasions and total antimicrobial consumption for a 12 week period. Post-intervention data were collected in the same manner and included assessment of compliance with RAMP in the intervention group (IG). RESULTS: The number of residents included was 1628 pre-intervention [825 IG/803 control group (CG)] and 1610 post-intervention (838 IG/772 CG). The corresponding pre- and post-intervention point prevalence of systemic antibiotic prescribing for treatment of infection was 6.46% and 6.52% in the IG [estimated prevalence ratio: 1.01 (95% CI: 0.81-1.25), P = 0.94] compared with 5.27% and 5.83%, respectively, in the CG [estimated prevalence ratio: 1.11 (95% CI: 0.87-1.41), P = 0.4]. Total antibiotic consumption was 69.78 defined daily doses/1000 residents/day (DRD) pre-intervention and 66.53 DRD post-intervention in the IG compared with 49.68 and 51.92 DRD, respectively, in the CG. There was a significant decrease of 4.9% (3.25 DRD) in the IG (95% CI: 1.0%-8.6%) (P = 0.02) compared with a significant increase of 5.1% (2.24 DRD) in the CG (95% CI: 0.2%-10.2%) (P = 0.04). Main indications for antibiotics were lower respiratory tract infections (34.1%), urinary tract infections (28.5%) and skin/soft tissue infections (25.1%). CONCLUSIONS: This pilot study demonstrated that use of RAMP was associated with a statistically significant decrease in total antibiotic consumption and has the potential to be an important antimicrobial stewardship tool for NHs.
