The multifactorial model of delirium was developed to explain the interrelationship between predisposing and precipitating factors for delirium. Although validated among hospitalized patients, this model has never been tested among long-term care residents with dementia. We undertook this secondary data analysis to investigate the combined effect of predisposing and precipitating factors on the likelihood of having delirium among this population. ⋯ When both variables were included in the same model, only predisposing factors remained statistically associated with delirium. Predisposing factors play a key role in the likelihood of having delirium among this population. Increased awareness of these factors among nurses could improve the care of these residents by targeting modifiable risk factors.

The aim of this study was to evaluate the predictive validity of the Braden Scale for Predicting Pressure Sore Risk in elderly residents of long-term care facilities (LTCFs) in Brazil. The determination of the cutoff score for the Brazilian population is important for the comparison between Brazilian and international studies and establishment of guidelines for prevention of pressure ulcers in our health care facilities. This is the first study of its kind in Brazil. ⋯ The best results were obtained for the total group, with cutoff scores of 18 and 17, sensitivity of 75.9% and 74.1%, specificity of 70.3% and 75.4%, and area under the receiver operating characteristic curve (AUC-ROC) of 0.79 and 0.81 at the first and last assessments, respectively. For the risk group, the cutoff scores of 16 (first assessment) and 13 (last assessment) were associated with a smaller AUC-ROC and, therefore, lower predictive accuracy. The Braden Scale showed good predictive validity in elderly LTCF residents.
