Utilization of Rehabilitation Services in Stroke: A Study Utilizing the Health and Retirement Study With Linked Medicare Claims Data.

To describe Medicare fee-for-service beneficiaries who used poststroke rehabilitation services and identified the strongest predictors of utilization after the initial stroke care episode. Pooled, cross-sectional design using data from 1998 to 2010 from the Health and Retirement Study (HRS) with linked Medicare claims data. NA. Stroke survivors who were Medicare fee-for-service beneficiaries and participated in the HRS were included (N=515). Utilization of rehabilitation services up to 10 years poststroke was the primary outcome with logistic regression used to predict utilization. Covariates included demographic factors, baseline functional status, health conditions, personal lifestyle factors, and social support. Rehabilitation service utilization was 21.6%, 6.8%, 15.8%, 16.5%, and <16% in years 2, 4, 6, 8, and 10, respectively. Age was the primary factor predicting use of rehabilitation in the first 10 years poststroke (odds ratio: 1.14; P=.001). Recurrent stroke (odds ratio: 1.64; P=.051) was also significantly associated with utilization, whereas unspecified incident stroke at incident trended toward significance (odds ratio: 2.17; P=.077). None of the other factors was a significant predictor of participation in rehabilitation services in this period. A small number of Medicare fee-for-service beneficiaries who are stroke survivors utilize rehabilitation services in the first 10 years poststroke. Of those who do, age is the primary driver of utilization. We analyzed a multitude of factors that might influence utilization, but other factors not available in these data also need to be explored.
