aHospital units grouped as intensive-care unit (ICU) or non-ICU units and by old or new hospital. All variables displayed in the table were included in the final model.
bAll hospital unit groups were compared to the two non-ICUs in the old hospital, i.e., the referent group, which had the lowest sink-to-bed ratios (1:6 and 1:11). All other units had a sink-to-bed ratio of 1:1.
