Emergence of Carbapenem-Resistant Acinetobacter baumannii in Nursing Homes With High Background Rates of MRSA Colonization.

Carbapenem-resistant Acinetobacter baumannii (CRAB) with diverse multilocus sequence typing emerged among our nursing home residents (6.5%) with a high background rate of MRSA (32.2%). Rectal swabs yielded a higher rate of CRAB detection than axillary or nasal swabs. Bed-bound status, use of adult diapers, and nasogastric tube were risk factors for CRAB colonization.

Transmission of methicillin-resistant Staphylococcus aureus in the long term care facilities in Hong Kong.

BACKGROUND: The relative contribution of long term care facilities (LTCFs) and hospitals in the transmission of methicillin-resistant Staphylococcus aureus (MRSA) is unknown. METHODS: Concurrent MRSA screening and spa type analysis was performed in LTCFs and their network hospitals to estimate the rate of MRSA acquisition among residents during their stay in LTCFs and hospitals, by colonization pressure and MRSA transmission calculations. RESULTS: In 40 LTCFs, 436 (21.6%) of 2020 residents were identified as 'MRSA-positive'. The incidence of MRSA transmission per 1000-colonization-days among the residents during their stay in LTCFs and hospitals were 309 and 113 respectively, while the colonization pressure in LTCFs and hospitals were 210 and 185 per 1000-patient-days respectively. MRSA spa type t1081 was the most commonly isolated linage in both LTCF residents (76/121, 62.8%) and hospitalized patients (51/87, 58.6%), while type t4677 was significantly associated with LTCF residents (24/121, 19.8%) compared with hospitalized patients (3/87, 3.4%) (p<0.001). This suggested continuous transmission of MRSA t4677 among LTCF residents. Also, an inverse linear relationship between MRSA prevalence in LTCFs and the average living area per LTCF resident was observed (Pearson correlation -0.443, p=0.004), with the odds of patients acquiring MRSA reduced by a factor of 0.90 for each 10 square feet increase in living area. CONCLUSIONS: Our data suggest that MRSA transmission was more serious in LTCFs than in hospitals. Infection control should be focused on LTCFs in order to reduce the burden of MRSA carriers in healthcare settings.

Using a community-based outreach program to improve breast health awareness among women in Hong Kong.

OBJECTIVE: To evaluate the effectiveness of a community-based health education program via a mobile van to promote the awareness of breast cancer and breast self-examination (BSE) practice among women in Hong Kong. DESIGN: One group pretest/posttest design. SAMPLE AND MEASUREMENTS: Seven hundred and seventy-seven women in Hong Kong completed a self-administered questionnaire before and after a breast health education program from May 2002 to March 2003. RESULTS: About half were aware of breast health and breast diseases (53.7%) and breast screening methods (48.6%) before the intervention. It was found that women who had received instruction on BSE practice, and those who were aware of breast screening methods, breast health, and breast diseases were more likely to have had prior BSE practice. Most indicated their willingness to practice BSE regularly (93.3%) and to pass on the BSE knowledge to their relatives and friends (92%) in the posttest. CONCLUSIONS: The outreach health education program has successfully reached women living in the 18 districts in Hong Kong. It appears to be useful in raising the awareness of breast health and BSE practice among the women, but longer term follow-up is required to ascertain its sustainability.
