Introduction
The aim of this study was to determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) both in rheumatologic and non-rheumatologic rehabilitation centers. In addition, we sought to evaluate the practice value of existing screening recommendations of the German Commission for Hospital Hygiene and Infection Prevention (KRINKO).
Methods
The analysis was performed in four rehabilitation clinics (rheumatology, psychosomatic medicine, oncology, and cardiology) with at least 200 patients per clinic tested for MRSA.
Results
Nine (1.1%) of the 842 patients were colonized with MRSA. Only five of them should have been tested according to the commission’s recommendations. The prevalence was 0.5% (n = 207) in rheumatologic, 0.9% (n = 224) in psychosomatic, 1.4% (n = 209) in oncologic and 1.5% (n = 202) in cardiologic patients. We found a greater exposure to risk factors in cardiologic and oncologic patients. Among patients with carrier status, a higher percentage was exposed to three potential risk factors not applied by the commission.
Conclusions
The prevalence of MRSA in our cohort correlates with data from previous studies. The low percentage among rheumatologic patients suggests that they are not more likely to reveal MRSA carrier status than other patient groups and that long-term immunosuppression does not necessarily represent a risk factor for MRSA colonization. Since only five out of nine patients with carrier status would have been detected following the recommendations of the KRINKO, further studies on potential risk factors are warranted.
