Lutz VA Medical Center, Saginaw, MI, USA Introduction: Effective post-acute multidisciplinary rehabilitation therapy improves stroke survivors’ functional recovery and daily living activities. The US Department of Veterans Affairs (VA) places veterans needing post-acute institutional care in private community nursing homes (CNHs). These placements are made under the same rules and regulations across the VA health care system and through individual per diem contracts between local VA facilities and CNHs. However, there is limited information about utilization of these veterans’ health services as well as the geographic variation of the service utilization. Aim: The aims of this study were to determine rehabilitation therapy and restorative nursing care utilization by veterans with stroke in VA-contracted CNHs and to assess risk-adjusted regional variations in the utilization of rehabilitation therapy and restorative nursing care. Methods: This retrospective study included all veterans diagnosed with stroke residing in VA-contracted CNHs between 2006 and 2009. Minimum Dataset (a health status assessment tool for CNH residents) for the study CNHs was linked with veterans’ inpatient and outpatient data within the VA health care system. CNHs were grouped into five VA-defined geographic regions: the North Atlantic, Southeast, Midwest, Continental, and Pacific regions. A two-part model was applied estimating risk-adjusted utilization probability and average weekly utilization days. Two dependent variables were rehabilitation therapy and restorative nursing care utilization by veterans during their CNH stays. Results: The study comprised 6,206 veterans at 2,511 CNHs. Rates for utilization of rehabilitation therapy and restorative nursing care were 75.7% and 30.1%, respectively. Veterans in North Atlantic and Southeast CNHs were significantly (p
