The Effect of Health Insurance Coverage on Orthopaedic Patient-reported Outcome Measures.

Abstract

Patient-reported outcome measures (PROMs) are used to assess performance and value. The type of health insurance coverage may influence outcomes scores. The goal of this study was to determine if the type of insurance coverage is associated with the trends in PROMs within an orthopaedic cohort. We reviewed the electronic medical records of 10,745 adult foot and ankle patients who completed PROMs questionnaires from 2015 to 2017. Patients completed the Foot and Ankle Ability Measure, PROMIS Global-Mental, PROMIS Global-Physical, and PROMIS Physical Function Short Form 10a. Descriptive analyses, analysis of variance, and Tukey HSD (honest significant difference) post hoc analyses were conducted. Patients with commercial insurance consistently had the highest outcomes scores, whereas those with Workers Comp/Motor Vehicle and Medicaid had the lowest. PROMs of patients with commercial insurance were statistically significantly higher than the pooled scores of all other patients. Markedly poorer scores were also seen for Workers Comp/Motor Vehicle and Medicaid. In addition, these differences in PROMs for Workers Comp/Motor Vehicle and Medicaid exceeded the minimal clinically important differences. Patients with Medicare or Free Care had generally lower scores than the pooled averages, but these results were not statistically significant. PROMs scores vary between the patients with different insurance types in an orthopaedic foot and ankle cohort. These data suggest that patient insurance type may affect patient-reported outcomes.
