ABSTRACT
INTRODUCTION: Patient-reported outcomes (PROs) provide data on the effect of conditions and treatments on patients' lives without third party interpretation. Mounting evidence suggests that PROs may be useful in elective procedure decision making, but its utility in trauma remains unclear. Longitudinally collected PROs may prove effective in identifying patients recovering below the norm. We sought to document recovery trajectory in patients with and without complication and to evaluate the sources of variability in functional recovery after injury. METHODS: This retrospective study included 831 patients with trauma, identified via Current Procedural Terminology (CPT) codes for surgical extremity and/or pelvic/acetabular fracture management between 2014 and 2018. Global Physical Health (GPH) scores collected via the PROMIS Global Health in a 14-month window after injury were analyzed using mixed-effects modeling. RESULTS: A curvilinear GPH recovery trajectory was observed where patients demonstrated an initial positive recovery trajectory (B = 1.28, P < 0.001) gradually decelerating over time (B = -0.07, P < 0.001). Patients who experienced complications requiring revision surgery demonstrated markedly lower GPH scores. Several notable predictors of postoperative physical health recovery were identified, including both between-person (B = 0.52, 95% CI, 0.48 to 0.56) and within-person (B = 0.41, 95% CI, 0.36 to 0.46) Global Mental Health (GMH) score, Body Mass Index (BMI) (B = -0.07, 95% CI, -0.12 to -0.02), two or more psychiatric diagnoses (B = -0.97, 95% CI, -1.84 to 0.09), Injury Severity Score 10 to 15 and 16+ (B = -2.62, 95% CI, -4.81 to 0.42 and B = -2.17, 95% CI, -3.60 to 0.74, respectively), readmission for complication (B = -2.64, 95% CI, -3.60 to 1.68), and lower extremity or multiextremity fracture (relative to upper extremity) (B = -3.61, 95% CI, 4.45 to 2.78, B = -4.11, 95% CI, -5.77 to 2.44, respectively). Additional analysis suggests that GMH scores are related to the presence of psychiatric diagnoses. DISCUSSION: This study establishes a normal course of recovery as reflected by PROMIS GPH score to serve as an index for monitoring individual postoperative course. Patients who experienced a complication demonstrated markedly lower GPH across all time points, potentially allowing earlier identification of at-risk patients. Furthermore, GMH may represent a modifiable risk factor that could profoundly affect physical recovery. LEVEL OF EVIDENCE: Level III (Prognostic Study = Retrospective Cohort).
