Musculoskeletal diagnoses, comorbidities, and physical and occupational therapy use among older adults with and without cerebral palsy.

BACKGROUND

Musculoskeletal (MSK) disorder in adults with cerebral palsy (CP) is higher than in the general population. Evidence lacks about physical therapy (PT) and occupational therapy (OT) service utilization among older adults (65> years) living with CP.

OBJECTIVE

We compared the presence of comorbidities and patterns of PT and OT use among older adults with and without CP seeking care for MSK disorders.

METHODS

A 20% national sample of Medicare claims data (2011-2014) identified community-living older adults with (n = 8796) and without CP (n = 5,613,384) with one or more ambulatory claims for MSK diagnoses. The sample matched one CP case to two non-CP cases per year on MSK diagnoses, age, sex, race, dual eligibility, and census region. Exposure variable was the presence/absence of a CP diagnosis. Outcomes were use of PT and OT services identified via CPT and revenue center codes, and the presence/absence of Elixhauser comorbidities.

RESULTS

In older adults with MSK diagnoses, less than a third regularly utilized PT and/or OT services, and adults with CP utilized significantly less PT than adults without CP, and for some MSK diagnoses had fewer visits than their matched peers. Older adults with CP were at greater risk for secondary conditions that influence morbidity, mortality, and quality of life compared to their age-matched peers without CP.

CONCLUSIONS

Older adults with CP and MSK diagnoses had a greater prevalence of numerous comorbidities and lower use of PT services relative to their non-CP peers.
