To utilize functional status () outcomes to benchmark outpatient therapy clinics.

Data Sources

Outpatient therapy data from clinics using Focus on Therapeutic Outcomes () assessments.

Study Design

Retrospective analysis of 538 clinics, involving 2,040 therapists and 90,392 patients admitted July 2006–June 2008. at discharge was modeled using hierarchical regression methods with patients nested within therapists within clinics. Separate models were estimated for all patients, for those with lumbar, and for those with shoulder impairments. All models risk‐adjusted for intake , age, gender, onset, surgery count, functional comorbidity index, fear‐avoidance level, and payer type. Inverse probability weighting adjusted for censoring.

Data Collection Methods

Functional status was captured using computer adaptive testing at intake and at discharge.

Principal Findings

Clinic and therapist effects explained 11.6 percent of variation in . Clinics ranked in the lowest quartile had significantly different outcomes than those in the highest quartile ( < .01). Clinics ranked similarly in lumbar and shoulder impairments (correlation = 0.54), but some clinics ranked in the highest quintile for one condition and in the lowest for the other.


Benchmarking models based on validated measures clearly separated high‐quality from low‐quality clinics, and they could be used to inform value‐based‐payment policies.
