Self-reported physical function strongly correlates with caregiver hours in spinal cord dysfunction patients. Higher disability levels showed more variability in care needs, highlighting the importance of functional measures.

Area of Science:

  • Rehabilitation Medicine
  • Clinical Epidemiology
  • Health Services Research

Background:

  • Spinal cord dysfunction presents significant challenges to patient independence and requires substantial care.
  • Understanding the relationship between patient-reported function and care needs is crucial for resource allocation and patient support.

Purpose of the Study:

  • To assess the association between self-reported physical function and the amount of care received in a large cohort of individuals with spinal cord dysfunction.
  • To evaluate the utility of self-reported disability measures in understanding the clinical epidemiology of spinal cord dysfunction.

Main Methods:

  • A cross-sectional, self-administered survey was used with 13,542 respondents from Department of Veterans Affairs databases.
  • Physical function was measured using the Self-Reported Functional Measure (SRFM).

  • Caregiver hours (CGHs) were self-reported over the preceding two weeks.

    • Main Results:

    • A strong negative correlation (Spearman correlation = -0.70) was observed between self-reported disability and CGHs.
    • Individuals with moderate disability levels exhibited the greatest variability in CGHs.
    • Instrumental activities of daily living and individual SRFM items were significant predictors of CGHs.

    Conclusions:

    • The findings support the construct validity of the Self-Reported Functional Measure.
    • Self-reported disability measures are valuable tools for describing the clinical epidemiology of spinal cord dysfunction.
