Abstract
We examined the external validation of the Prediction for Resuming Domestic Chores After Stroke (PRDCAS) models in forty-six stroke patients admitted to a recovery rehabilitation ward. First, we used the PRDCAS models to predict whether each stroke patient resumed the six items of domestic chores (preparing meals, washing dishes, washing clothes, light housework, heavy housework, and local shopping) after discharge. Next, we investigated resumption status of domestic chores three months after discharge. After that, the prediction accuracy of each model was calculated, and the discrimination was assessed using the Area Under the Curve of Receiver Operator Characteristic curve. As a result, the prediction accuracy for each item ranged from 75.0 to 82.2%, and the AUC ranged from 0.71 to 0.86. The results of this study indicate moderate accuracy of the PRDCAS models.
