BACKGROUND: We previously reported a 3 month prospective study performed in 4 rehabilitation units (RU)(04-06/98), in order to evaluate colonization by MRSA. All patients had had systematic sampling (SS) of nose, perineum and wounds; contact isolation universal precautions were applied if one or more sample was positive. Colonization rate at admission was 17.8%, at discharge 30.4% and acquisition rate 24.3%.METHODS: We performed a prospective simple blind study (04-06/99) in the same RU, in order to analyze interest of SS. All patients admitted had SS of nose, perineum and wounds at admission and at discharge but results were not send to practitionners, contact isolation universal procedures were not emphasized. In the same time, patients with wounds had an other sampling of which results were available for practitionners, contact isolation universal precaution were applied if one or more sample was positive.RESULTS: 281 patients (173M, 108F, mean age = 79.5 years) were included (vs 265, mean age 81 years/1998). 41 patients were colonized at admission (14.6% vs 17.7%/1998, ns). Among them 17 were known by practitionners and 24 remain unknown during all the stage. 61 patients were colonized at discharge (28% vs 30.4%/1998, ns), 35 acquired MRSA during the hospitalisation (19% vs 24.3%/1998, p<0.05). Regarding to clinical data, risk factors for colonization by MRSA were not different between the 2 periods. Conclusion: Despite the fact that half of the colonized patients at admission remain unknown by staff, acquisition rate was not higher than in 1998. Acquisition rate appeared to be unchanged whatever all patients or only those with wounds had sampling at admission. Screening for MRSA colonization at admission should be considered only in patients with wounds.KEYWORDS: MRSA; Rehabilitation unit; Systematic sampling
