Public sector residential aged care: identifying novel associations between quality indicators and other demographic and health-related factors

<b>Objective : </b>To explore associations among quality indicators (QI; e.g. pressure ulcers, falls and/or fractures, physical restraint, use of multiple medications, unplanned weight loss) of the Victorian Public Sector Residential Aged Care Services (VPSRACS) with other demographic and health-related factors.<br /><br /><b>Methods : </b>Data for 380 residents over a 3-month period were extracted retrospectively from client databases at four VPSRAC facilities.<br /><br /><b>Results :</b> Four significant logistic regression models were developed. The strongest models related to falls and polypharmacy. Significant associations for these models included the following: (1) residents with a higher body mass index were 6% less likely (95% confidence interval (CI) 1%–11%) to fall, whereas high levels of cognitive impairment increased the risk of falling by 8% (95% CI 2%–14%); (2) being ambulant with a gait aid more than doubled the risk of falling compared with non-ambulant residents (95% CI 19%–546%); and (3) higher cognitive impairment was associated with a 6% (95% CI 1%–11%) reduction in the likelihood of polypharmacy.<br /><b><br />Conclusions :</b> Identification of significant relationships between the VPSRACS QI and other demographic and health-related factors is a preliminary step towards a more in-depth understanding of the factors that influence the QI and predict adverse events.
