a Admission prevalence swabs were not collected for nursing homes 20 through 26 due to small facility size and minimal resident turnover.
b Estimated transmission risk was calculated as the absolute difference (MRSA point – admission prevalence) divided by the number of at risk patients per 100 admitted. For example, for NH3, transmission risk = (30% - 8%) / (100–8) = 24%.
