“…We also look at potentially adjustable within-facility staff variables, such as level of emotional support for staff, the way shifts are organized, staff ratios, but not at broad facility level variables such as type of unit (for example Special Care Units (SCU) vs. nursing home), which is not an accurate enough variable and is an area already heavily reviewed with equivocal results (e.g. Rosewarne et al, 1997a;Chappell and Reid, 2000). We do look at relevant care characteristics sometimes associated with SCUs, if measured, but our interest is in what staff actually do rather than the broad label applied to where they do it.…”
