The relationship between patient-specific factors and functional progression of COVID-19 survivors admitted to an inpatient rehabilitation facility

Abstract

Background: Survivors of hospitalization for severe acute COVID-19 infection faced significant functional impairments necessitating discharge to inpatient rehabilitation facilities (IRFs) for intensive rehabilitation prior to discharge home. There remains a lack of large cohort studies of the functional outcomes of patients admitted to IRFs with COVID-19-related impairments and the relationship to patient-specific factors.

Objective: To characterize functional outcomes of patients admitted to IRFs for COVID-19-related debility and to investigate associations between functional outcomes and patient-specific factors.

Design: Multisite retrospective cohort study.

Setting: Multiple IRFs in a large urban city.

Participants: Adult patients admitted to IRFs for rehabilitation after hospitalization for acute COVID-19 infection.

Interventions: Not applicable.

Main outcome measures: Primary outcomes included change in GG Self-Care and Mobility Activities subscales and Functional Independence Measure scores from admission to discharge from inpatient rehabilitation. Linear regression analysis was used to relate functional changes to demographic, medical, and hospitalization-specific factors. Secondary outcomes included discharge destination from the IRF.

Results: The analysis included n = 362 patients admitted to IRFs for COVID-19-related rehabilitation needs. This cohort showed significant improvements in mobility, self-care, and cognition congregate scores (216.0%, 174.3%, 117.6% respectively). Patient-specific factors associated with functional improvement included age, body mass index, premorbid employment status, history of diabetes and cardiac disease and medications received in acute care, and muscle strength upon admission to IRF.

Conclusions: Patients admitted to inpatient rehabilitation for COVID-19-related functional deficits made significant functional improvements in mobility, self-care, and cognition. Many significant associations were found between patient-specific factors and functional improvement, which support further investigation of these factors as possible predictors of functional improvement in an IRF for COVID-19-related deficits.
