Evaluating Intervention Allocation Policies for Reducing Hospital Readmissions at Michigan Medicine

The intervention affects only how the TOC bundle is assigned and does not alter how the telephone calls are delivered. For example, both care navigators and pharmacists receive the same patient information and follow the same call procedures before and after the intervention.

Individuals with predicted benefits greater than the 40% quantile are assigned the phone call bundle while others were not assigned the bundle. During the trial the 40% quantile will be dynamically determined using discharge data from the previous week.
