Importance of Outcome Domain for Patients With Musculoskeletal Pain: Characterizing Subgroups and Their Response to Treatment.

Giorgio Zeppieri, Joel Bialosky, Steven Z George

PMID 31944245

WHAT IT FOUND

Patients with musculoskeletal pain were grouped by what they wanted to improve.

Those valuing pain and function were more satisfied at 6 months. The group that rated pain as its top priority did not have better pain response, and disability change differed by group.

Key findings

01A three-cluster solution for outcome importance was observed in both development and validation cohorts.

02Pain response did not differ by importance subgroup, but disability change differed from baseline to 4 weeks.

03The subgroup that valued pain and function had higher 6-month satisfaction.

What it does not show

The sample was a convenience sample from outpatient physical therapy clinics, so it may not represent all patients with musculoskeletal pain. Participants were excluded if they had chronic pain syndrome, neuropathic pain, psychiatric history, active cancer, or neurological disorders, so the findings may not apply to those groups. The study did not document or control the physical therapy treatments given, so differences in response or satisfaction cannot be linked to any specific treatment approach. Importance was measured only at baseline, and patient preferences may change during an episode of care. The pain-focused subgroup also had lower distress, interference, and disability, so their low importance ratings may reflect a less complex presentation rather than a pure focus on pain. This was a secondary analysis of a cohort study, not a trial, so it cannot show that matching treatment to a patient's preferred outcome causes better results. The study did not test whether using the PCOQ in routine care improves outcomes.

Declared interests

The article reports non-U.S. government research support and states that the funder played no role in the design, conduct, or reporting of the study. No additional conflict of interest information is provided in the supplied text.

The easy way to misread this

Do not conclude that patients whose top priority is pain will get better pain relief or that matching treatment goals to those preferences improves outcomes. The group that rated pain as its top priority did not have better pain response, and the study did not document or control the treatments given.
