Identification of Disability Subgroups for Patients After Ischemic Stroke.

Area of Science:

• Neurology
• Rehabilitation Medicine
• Health Services Research

Background:

• Ischemic stroke leads to diverse patient disabilities, complicating standardized care.
• Understanding disability heterogeneity is crucial for effective post-stroke management.
• Previous classifications may not fully capture the spectrum of post-stroke functional impairment.

Purpose of the Study:

• To identify distinct disability subgroups among patients hospitalized for ischemic stroke.
• To determine predictors associated with these disability subgroups.
• To analyze the distal outcomes, including treatment utilization and discharge disposition, for each subgroup.

Main Methods:

• Retrospective, cross-sectional study utilizing electronic health records from 5 hospitals.
• Latent class analysis applied to characterize disability based on the Activity Measure for Post-Acute Care.
• Analysis included social, demographic factors, and post-acute care outcomes.

Main Results:

• Five disability subgroups were identified: globally impaired, impaired dynamic balance, impaired self-care, impaired mobility, and independent.
• Significant variations in physical and occupational therapist treatment use were observed across subgroups.
• Discharge disposition, including home without services, home with services, and institutional discharge, differed significantly among the identified subgroups.

Conclusions:

• The identified disability subgroups offer a standardized framework for describing post-stroke functional status.
• These subgroups can enhance communication and decision-making within multidisciplinary stroke care teams.
• Tailoring rehabilitation interventions based on subgroup membership may improve patient outcomes.
