Records of 52 Medicaid managed care psychiatric patients engaged in a home intervention program (HIP) were analyzed to determine (a) if home-based intervention reduced a participant's readmission rates to an inpatient behavioral health facility and (b) if a negative relationship existed between total HIP sessions and readmissions following the implementation of home-based services. A paired t test comparing admissions 6 months prior to HIP with admissions 6 months after HIP demonstrated an average decrease of readmissions by 2.5 (p < .0001), or 86%. These results supported the hypothesis that HIP reduces participants' readmission rates.
