The SHIELD Orange County Project -Multi Drug-Resistant Organism (MDRO) Prevalence in 21 Nursing Homes and Long Term Acute Care Facilities in Southern California.
Clinical infectious diseases : an official publication of the Infectious Diseases Society of America
Background: Multidrug-resistant organisms (MDROs) spread between hospitals, nursing homes (NH), and long-term acute care facilities (LTACs) via patient transfers. SHIELD OC is a regional public health collaborative involving decolonization at 38 healthcare facilities selected based upon their high degree of patient sharing. We report baseline MDRO prevalence in 21 NH/LTACs.
Methods: A random sample of 50 adults for 21 NH/LTACs (18 NHs, 3 LTACs) were screened for methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus spp. (VRE), extended-spectrum beta-lactamase producing organisms (ESBL), and carbapenem-resistant Enterobacteriaceae (CRE) using nares, skin (axilla/groin), and peri-rectal swabs. Facility and resident characteristics associated with MDRO carriage were assessed using multivariable models clustering by person and facility.
Results: Prevalence of MDROs was 65% in NHs and 80% in LTACs. The most common MDROs in NHs were MRSA (42%) and ESBL (34%); in LTACs they were VRE (55%) and ESBL (38%). CRE prevalence was higher in facilities that manage ventilated LTAC patients and NH residents (8% vs.
Conclusions: The majority of NH residents and LTACs patients harbor MDROs. MDRO status is frequently unknown to the facility. The high MDRO prevalence highlights the need for prevention efforts in NH/LTACs as part of regional efforts to control MDRO spread.
