- 1Baseline: October 2016–December 2016, Follow-up 1: January 2017–April 2017, Follow-up 2: May 2017–October 2017. 2The results were corrected for the clustering of infection registrations within nursing homes, baseline differences and period in the study, in a multilevel Poisson regression. 3The sensitivity analysis excluded the highest 1% incident rates per HAI per week. 4Could not fit model due to convergence issues.
