Introduction / objectives

Knowledge of local MRSA epidemiology at both facility and ward level helps target control measures. This study aimed to determine the prevalence of and risk factors for MRSA colonisation on admission to different healthcare sectors in two European countries.


Four centres in Spain and France enrolled in 3 intervention trials of MRSA control performed universal MRSA screening on admission to intensive care units (ICUs), surgical wards and rehabilitation units from August 2008 to March 2010. Demographic and comorbidity data were collected. Univariate and multivariate logistic regression analyses were used to identify risk factors for unknown MRSA carriage on admission.


Overall, 1780 previously unknown MRSA carriers were screened, 403 (23%) in ICUs, 1099 (62%) in surgical wards and 278 (16%) in rehabilitation wards. The prevalence of unknown MRSA carriage on admission was 2.7% in ICUs, 3.6% in surgical wards and 7.9% in rehabilitation units. No independent risk factors for MRSA carriage on admission to the ICUs were found. Risk factors for surgical wards were age, wounds, nursing home residency and tracheostomy. Rehabilitation unit risk factors were renal failure, diabetic foot, recent antibiotic use and neuro-rehabilitation.


Prevalence and risk profiles for MRSA carriage on admission to different healthcare sectors varied widely, emphasising the importance of local surveillance data to enable adaptation of MRSA control policies at the ward level.
