PurposeThe Pressure Injury Primary Risk Assessment Scale for Home Care (PPRA-Home) was developed to predict pressure injury risk in geriatric individuals requiring long-term care in home settings. This study aimed to compare the convergent validity of the PPRA-Home to that of the two other standardized pressure injury prevention scales: the Braden and Ohura-Hotta (OH) scales.MethodsA multicenter, cross-sectional study was conducted with 34 home-based geriatric support service providers located in five Japanese districts. The study included 69 participants (30 had a pressure injury and 39 did not) who were at classified at care levels of 1 through 5 under Japan's long-term care insurance system. Care managers served as assessors for the PPRA-Home, while physicians or certified expert nurses served as assessors for the Braden and OH scales. Convergent validity was investigated by examining correlation coefficients between total scores on the PPRA-Home and the other two scales. Receiver operating curve analysis was used to quantify each scale's accuracy for the two groups: those with and without a pressure injury.ResultsThe PPRA-Home was found to be negatively correlated with the Braden scale (r=-0.79, p<0.05), and positively correlated with the OH scale (r=0.58, p<0.05). The area under the curve (AUC) for the PPRA-Home, Braden scale, and OH scale were 0.737, 0.814, and 0.794, respectively. A PPRA-Home cutoff score of 4 had a sensitivity of 63.3% and specificity of 81.6%.ConclusionThe AUC for the PPRA-Home as scored by care managers was similar to those of the Braden and OH scales as scored by physicians or expert nurses. More research on the PPRA-Home's content and predictive validity is required.© 2021 Kohta et al.
