Objective To examine trends in functional outcomes, LOS among patients with hemorrhagic versus ischemic stroke in IRF.

Background Functional outcomes and length of stay (LOS) are outcome measures in stroke patients at Inpatient Rehabilitation Facilities (IRF).

Design/Methods Using a prospective database of stroke patients admitted to our health system of 5 IRFs, we reviewed patients with either ischemic or hemorrhagic stroke between 5/18 to 5/19. Outcome measures included the FIM scores and LOS. The relationship between LOS and FIM improvement were analyzed using a third order polynomial regression model, adjusted for patient’s age.

Results Among 111 patients, 42% were female, 58% had an ischemic stroke and 42% had a hemorrhagic stroke. The median LOS was 21 days (IQR14,27) for all patients: 20 (IQR12,29) in hemorrhagic stroke, 21 (IQR14,25) in ischemic stroke (P=0.65). Patients 70 or older had median LOS of 17 days (IQR 12, 22), significantly less than LOS in patients younger than 60 (median 22.5, IQR 16, 31, P=0.011). Patients with history of prior stroke had less improvement in FIM score but the difference was not statistically significant (26.1vs 28.8, P=0.46). The number of risk factors also did not have any statistically significant effects on outcomes. The correlation analysis showed that patient's age was negatively correlated with FIM score improvement (r=-0.18, P=0.05). Based on regression analysis, stroke patients benefited the most from IRF in the first 17 days (P<.0001) while the improvement rate declined significantly afterwards. The highest FIM score change was 37.4 for patients younger than 60 . Compared to patients younger than 60, patients aged 60 or older had significantly less FIM score improvement (difference=-6.4,P=0.047 for 60-69 vs. <60, difference=-6.9, P=0.037 for ≥70 vs. <60 ).

Conclusions Stroke patients in our IRF network benefited the most on FIM in the first 17 days. Patients younger than 60 years had the greatest improvement.
