Variable performance of models for predicting methicillin-resistant Staphylococcus aureus carriage in European surgical wards.

Background: Predictive models to identify unknown methicillin-resistant Staphylococcus aureus (MRSA) carriage on admission may optimise targeted MRSA screening and efficient use of resources. However, common approaches to model selection can result in overconfident estimates and poor predictive performance. We aimed to compare the performance of various models to predict previously unknown MRSA carriage on admission to surgical wards.

Hand hygiene practices and adherence determinants in surgical wards across Europe and Israel: a multicenter observational study.

We examined hand hygiene practices in surgical wards in 9 countries in Europe and Israel through direct practice observation. There was marked interhospital variation in hand hygiene compliance (range, 14%-76%), as well as glove and alcohol-based handrub use. After multivariable analysis, surgical subspecialty, professional category, type of care activity, and workload were independently associated with compliance.
