Physical Therapy Use, Costs, and Value for Latent Classes of Good vs Poor Outcome in Patients Who Catastrophize About Their Pain Prior to Knee Arthroplasty.

ABSTRACT:

Objective

To examine use, costs, and value of physical therapy (PT) among subgroups.

Design

We conducted an observational study of data from a randomized trial of a pain coping skills intervention. Good and poor outcome subgroups were determined based on Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC) Pain and Physical Function scores. The use and costs of PT care as well as changes in WOMAC Pain and Physical Function scores over 4 time periods during a 1-year follow-up were reported. We compared the number of PT visits, total PT costs, and cost per 1-unit improvement in WOMAC scores for the 2 latent subgroups.

Setting

Five academic medical centers.

Participants

Patients who catastrophized about their pain prior to knee arthroplasty (N=3
