BACKGROUND Hand hygiene is the single-most important nursing home (NH) infection control measure. We piloted a multifaceted hand-washing/surface cleaning intervention in 5 NHs. Our aims were to assess the feasibility of implementing this intervention by assessing staff participation, satisfaction, hand-washing compliance, and whether the intervention was associated with reductions in infection rates, new antimicrobial orders, or overall hospitalization rates. METHODS We conducted a randomized, pair-matched pilot intervention in 10 Colorado NHs to reduce infections for all NH residents from October 1, 2015 through May 31, 2016. To evaluate process, we determined online education participation rates, recorded intervention fidelity through weekly reporting measures on microbial surface counts, hand-washing, and infection reporting, and conducted a survey of participating employees. To evaluate potential impacts on clinical outcomes, we collected information on monthly infection log data, new antibiotic orders, and hospitalizations. RESULTS Three of 5 sites had education participation rates >90%, the other 2 were poor (13% and 23%). The majority of participation survey respondents (58%) were promoters of the intervention. Directors of nursing reported hygiene hand-washing data for 19.6/24 (81.8%) weeks and microbial surface count data for 20.4/24 (85.1%) weeks. For the first 4 weeks of the study, the bacterial counts averaged 351.4 ± 497.5 relative light units, the mean value for the last 4 weeks was 127.7 ± 85.1 (P value = .12). The number of hand-washing occasions per NH resident was steady over time but differed by treatment facility (P = .03). We observed nonsignificant reductions for total infections (6.7%) and lower respiratory tract infections (19.9%) vs control NHs. There were no significant differences in antimicrobial orders or hospitalization rates pre-post intervention. CONCLUSIONS This multifaceted hand-washing and surface cleaning intervention was designed to reduce infection rates among NH residents. In our 10-facility randomized, matched pair pilot study, we observed program compliance and satisfaction along with reductions in surface bacterial counts, but did not observe a statistically significant reduction in infection rates, antimicrobial use, or hospitalizations.
