Rates of Inpatient and Emergency Room Use Before and After Discharge Among Medicaid Enrollees in OnTrackNY.

This study examined hospital and emergency room (ER) use among Medicaid enrollees before and after discharge from OnTrackNY, a coordinated specialty care program for recent-onset psychosis. Medicaid claims data were linked to program data. Inpatient hospitalization, inpatient days, and ER visits were assessed in the 6 months prior to OnTrackNY enrollment and 6 months prior to and after discharge. The sample consisted of 138 participants with continuous Medicaid enrollment during the study. Inpatient visits significantly declined from the pre-OnTrackNY enrollment period to the predischarge period (β=-1.23, standard error [SE]=0.22, p<0.001), did not significantly change in the first 6 months after discharge (β=0.19, SE=0.26, p=0.48), and remained significantly lower than before OnTrackNY enrollment (β=-1.05, SE=0.20, p<0.001). Similar patterns were observed for inpatient days and ER use. ER and hospital use declined during OnTrackNY participation and did not significantly change in the first 6 months after discharge.
