Are short training sessions on hand hygiene effective in preventing hospital-acquired MRSA? A time-series analysis

We tested the impact of short hand hygiene training sessions and bed occupancy rates on the spread of hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) using a multivariate time-series analysis. According to our model, bed occupancy rates within general ward and intensive care unit settings correlated positively with the incidence of hospital-acquired MRSA, whereas alcohol-based hand rub use and MRSA showed a negative correlation. Furthermore, our model shows that 2 hand hygiene campaigns based on short training sessions effected a long-run reduction in the incidence of hospital-acquired MRSA.
