Longitudinal Predictors of PROMIS Satisfaction With Social Roles and Activities After Shoulder and Knee Sports Orthopaedic Surgery in United States Military Servicemembers: An Observational Study.

BACKGROUND

Satisfaction with social roles and activities is an important outcome for postsurgical rehabilitation and quality of life but not commonly assessed.

PURPOSE

To evaluate longitudinal patterns of the Patient-Reported Outcomes Measurement Information System (PROMIS) Satisfaction with Social Roles and Activities measure, including how it relates to other biopsychosocial factors, before and up to 6 months after sports-related orthopaedic surgery.

STUDY DESIGN

Cohort study (diagnosis); Level of evidence, 3.

METHODS

Participants (N = 223) who underwent knee and shoulder sports orthopaedic surgeries between August 2016 and October 2020 completed PROMIS computer-adaptive testing item banks and pain-related measures before surgery and at 6-week, 3-month, and 6-month follow-ups. In a generalized additive mixed model, covariates included time point; peripheral nerve block; the PROMIS Anxiety, Sleep Disturbance, and Pain Behavior measures; and previous 24-hour pain intensity. Patient-reported outcomes were modeled as nonlinear (smoothed) effects.

RESULTS

The linear (estimate, 2.06; 95% CI, 0.77-3.35; = .002) and quadratic (estimate, 2.93; 95% CI, 1.78-4.08; < .001) effects of time, as well the nonlinear effects of PROMIS Anxiety ( < .001), PROMIS Sleep Disturbance ( < .001), PROMIS Pain Behavior ( < .001), and pain intensity ( = .02), were significantly associated with PROMIS Satisfaction with Social Roles and Activities. The cubic effect of time ( = .06) and peripheral nerve block ( = .28) were not. The proportion of patients with a 0.5-SD improvement in the primary outcome increased from 23% at 6 weeks to 52% by 6 months postsurgery, whereas those reporting worsening PROMIS Satisfaction with Social Roles and Activities decreased from 30% at 6 weeks to 13% at 6 months.

CONCLUSION

The PROMIS Satisfaction with Social Roles and Activities measure was found to be related to additional domains of function (eg, mental health, behavioral, pain) associated with postsurgical rehabilitation.
