Risk factors for methicillin-resistant Staphylococcus aureus carriage in residents of German nursing homes.
Infect Control Hosp Epidemiol 2002; 23(9):511-5IC

Abstract

OBJECTIVES

To determine the prevalence of and the risk factors for methicillin-resistant Staphylococcus aureus (MRSA) carriage in nursing home residents in the Rhine-Neckar region of southern Germany.

DESIGN

Point-prevalence survey.

SETTING

Forty-seven nursing homes in the region.

PARTICIPANTS

All residents of the approached nursing homes who agreed to participate.

METHODS

After informed consent was obtained, all participants had their nares swabbed, some personal data collected, or both. All swabs were examined for growth of MRSA. All S. aureus isolates underwent oxacillin susceptibility testing and polymerase chain reaction for demonstration of the mecA gene. All MRSA isolates were typed using pulsed-field gel electrophoresis after digestion with SmaI.

RESULTS

Swabs from 3,236 nursing home residents yielded 36 MRSA strains, contributing to a prevalence rate of 1.1%. Significant risk factors for MRSA carriage in the multivariate analysis were the presence of wounds or urinary catheters, limited mobility, admission to a hospital during the preceding 3 months, or stay in a medium-size nursing home. One predominant MRSA strain could be detected in 30 of the 36 MRSA carriers.

CONCLUSIONS

The prevalence of MRSA in German nursing homes is still low. These residents seemed to acquire their MRSA in the hospital and transfer it to their nursing home. Apart from well-known risk factors for the acquisition of MRSA, we identified the size of the nursing home as an independent risk factor. This might be due to an increased use of and microbials in nursing homes of a certain size.
