Study design to develop the next 6-month health care resource utilization predictive algorithm. Maine HIE data were split into retrospective and prospective cohorts based on different time frames. A decision tree–based model estimated the health care resource utilization risks in the next 6 months by statistically learning the preceding 12-month clinical histories and were trained, calibrated, and blind tested with the retrospective cohort. The predictive risk model was then validated with the prospective cohort.
