An evaluation of care coordination in controlling inpatient hospital utilization of people with developmental disabilities

All admissions of people with developmental disabilities to a community hospital over 3 years were examined to evaluate the impact of a coordinated care model on length of stay and hospital charges. Admissions were divided into two groups, those receiving either coordinated care (program group) or routine care by community physicians (usual care group). The program group had shorter average lengths of stay and lower hospital charges than did the usual care group, especially when charges were adjusted for case mix. Similarity of severity across the groups was measured by number of discharge diagnoses and Medicaid case weights. Over the 3 years, for the 115 admissions in the program group, these differences amounted to more than $200,000 in potentially unnecessary hospital charges. Implications of care coordination services for community-based health care planning were presented.
