Kind AJH, Smith MA, Liou J-I, Pandhi N, Frytak JR, Finch MD. Discharge destination's effect on bounce-back risk in black, white, and Hispanic acute ischemic stroke patients. Arch Phys Med Rehabil 2010;91:189-95. Objective: To determine whether racial and ethnic effects on bounce-back risk (ie, movement to settings of higher care intensity within 30d of hospital discharge) in acute stroke patients vary depending on initial posthospital discharge destination. Design: Retrospective analysis of administrative data. Setting: Four hundred twenty-two hospitals, southern/eastern United States. Participants: All Medicare beneficiaries 65 years or more with hospitalization for acute ischemic stroke within one of the 422 target hospitals during the years 1999 or 2000 (N=63,679). Interventions: Not applicable. Main Outcome Measures: Adjusted predicted probabilities for discharge to and for bouncing back from each initial discharge site (ie, home, home with home health care, skilled nursing facility [SNF], or rehabilitation center) by race (ie, black, white, and Hispanic). Models included sociodemographics, comorbidities, stroke severity, and length of stay. Results: Blacks and Hispanics were significantly more likely to be discharged to home health care (blacks=21% [95% confidence interval (CI), 19.9-22.81, Hispanic=19% [17.1-21.7] vs whites=16% [15.5-16.8]) and less likely to be discharged to SNFs (blacks=26% [95% CI, 23.6-29.3], Hispanics=28% [25.4-31.6] vs whites=33% [31.8-35.1]) than whites. However, blacks and Hispanics were significantly more likely to bounce back when discharged to SNFs than whites (blacks=26% [95% CI, 24.2-28.6], Hispanics=28% [24-32.6] vs whites=21% [20.3-21.9]). Hispanics had a lower risk of bouncing back when discharged home than either blacks or whites (Hispanics=14% [95% CI, 11.3-17] vs blacks=20% [18.4-22.2], whites=18% [16.8-18.3]). Patients discharged to home health care or rehabilitation centers demonstrated no significant differences ill bounce-back risk. Conclusions: Racial/ethnic bounce-back risk differs depending on initial discharge destination. Additional research is needed to fully understand this variation in effect.
