Abstract: Explores whether there is a relationship between staffing and quality indicators in residential care of older people, in both rest homes and continuing-care hospitals. Conducts a longitudinal survey of 18 residential-care rest homes and 16 continuing-care hospitals in the greater Auckland region to explore the relationship between direct-care staffing levels, skill mix and quality indicators. Collects data over a 6-month period on type of staffing, including registered nurses, enrolled nurses, and support workers; quality indicators, including falls, new fractures, pressure ulcers, weight loss, urinary tract infections (UTI), poly-pharmacy or multiple medications, presence of indwelling catheters and use of daily restraints. Uses logistic analysis to analyse the inverse relationship between staffing levels and adverse events, and whether there is an association between staff type and the incidence of the five quality indicators.
