To examine the relationship between the predictor variable, readiness for discharge, and the primary outcomes, a correlation analysis was first performed. A significant correlation between readiness for discharge (as a continuous variable) and the physician communication composite domain was found (rs 1⁄4 0.309; p < 0.001; Fig. 2A). This was true with either method of calculating the physician communication composite. In addition, the 2 methods for calculating the physician communication composite had a very strong correlation with one another (rs 1⁄4 0.997; p < 0.001). When comparing readiness for
