For aim 1, the estimated sample size to detect an average difference of 8 days in time to resolution with a standard deviation of 20 and an intra-cluster correlation (ICC) of 0.025. With alpha .05 and beta .80, the study would need a minimum 26 providers enrolled with an average 10 patient participants in each provider's cluster for a total of 286 participants completing the study. We planned to enroll at least 30 providers and up to 500 patients to insure against loss to follow-up of, increased standard deviation, or larger than anticipated Intra-Cluster Correlation.
