Adherence to Post-Acute Rehabilitation Guidelines Improves Functional Recovery in Stroke

Abstract

97 Purpose & Methods: To assess if compliance with post-stroke rehabilitation guidelines improves functional recovery. The design of the study was an inception cohort of stroke patients followed prospectively for 6 months. The setting was eleven Department of Veteran Affairs Medical Centers providing care to stroke patients. The subjects included 288 selected patients with stroke admitted between January 1998 - March 1999. Data were abstracted from medical records and telephone interviews. Primary outcome was the Functional Independence Motor Score (FIM). Secondary outcomes included Instrumental Activities of Daily Living (IADL), SF-36 physical functioning, and the Stroke Impact Scale (SIS). Acute and post-acute rehabilitation composite compliance scores (range 0–100) were derived from an algorithm. All outcomes were adjusted for case mix. Results: Average compliance scores in acute and post acute care settings were 68.2% (+ 14) and 69.5% (+ 14.4), respectively. After case-mix adjustment, level of compliance with post-acute rehabilitation guidelines was significantly associated with FIM motor, IADL, and the SIS physical domain scores. SF-36 physical function scores and mortality were not affected by compliance with post-acute rehabilitation guidelines. Level of compliance with rehabilitation guidelines in acute settings was unrelated to any of the outcome measures. Conclusion: Process of care in post-acute stroke rehabilitation affects 6-month functional recovery. Our findings support the use of guidelines as means of assessing quality of care and improving outcomes. These quality indicators are needed to ensure that quality of care is not comprised with new organizational and funding changes involving post-acute stroke care.
