    BackgroundThe spread of multidrug-resistant organisms (MDROs) is a global concern, and much about transmission in healthcare systems remains unknown. To reduce hospital stays, nursing facilities (NFs) have increasingly assumed care of post-acute populations. We estimate the prevalence of MDRO colonization in NF patients on enrollment and discharge to community settings, risk factors for colonization, and rates of acquiring MDROs during the stay.MethodsWe conducted a prospective, longitudinal cohort study of newly admitted patients in 6 NFs in southeast Michigan using active microbial surveillance of multiple anatomic sites sampled at enrollment, days 14 and 30, and monthly thereafter for up to 6 months.ResultsWe enrolled 651 patients and collected 7526 samples over 1629 visits, with an average of 29 days of follow-up per participant. Nearly all participants were admitted for post-acute care (95%). More than half (56.8%) were colonized with MDROs at enrollment: methicillin-resistant Staphylococcus aureus (MRSA), 16.1%; vancomycin-resistant enterococci (VRE), 33.2%; and resistant gram-negative bacilli (R-GNB), 32.0%. Risk factors for colonization at enrollment included prolonged hospitalization (>14 days), functional disability, antibiotic use, or device use. Rates per 1000 patient-days of acquiring a new MDRO were MRSA, 3.4; VRE, 8.2; and R-GNB, 13.6. MDRO colonization at discharge was similar to that at enrollment (56.4%): MRSA, 18.4%; VRE, 30.3%; and R-GNB, 33.6%.ConclusionsShort-stay NF patients exhibit a high prevalence of MDROs near the time of admission, as well as at discharge, and may serve as a reservoir for spread in other healthcare settings. Future interventions to reduce MDROs should specifically target this population.
