Patient Expectations for Symptomatic Improvement before Cubital Tunnel Release

Abstract

Background: Patient expectations before cubital tunnel release (CuTR), a common procedure that leads to incomplete symptom resolution for many patients, are unclear. Study purposes included (1) describing preoperative patient expectations, and (2) identifying factors affecting expectations. Methods: Included patients underwent isolated unilateral CuTR between 2015 and 2021 at a single tertiary academic medical center. Expectations regarding the level of symptomatic improvement were queried preoperatively. Univariate and multivariable binary logistic regression was performed to determine factors associated with expecting great improvement. Results: Of the 92 included patients, 43 (47%) patients expected great improvement, whereas 27 (29%), four (4%), and five patients (5%) expected some, little, and no improvement, respectively. The remainder (14%) had no expectations. Multivariable modeling demonstrated that retired or unemployed/disabled work status, and commercial insurance status (versus Medicare or Medicaid) were associated with lower expectations independent of the surgeon, surgical technique, revision versus primary CuTR, preoperative atrophy or constant numbness, diabetes, and all studied demographic factors, including social deprivation. Conclusions: Roughly half of the patients expect great relief, and a third expect lesser degrees of relief, following CuTR. Preoperative expectations are significantly higher in patients with Medicaid and Medicare insurance, representing an opportunity for education, given the association between public insurance payer status and worse health outcomes in general. Age, BMI, preoperative atrophy and/or numbness, and the presence of medical comorbidities do not influence expectations but have been shown to yield worse outcomes or influence need for revision CuTR, representing an opportunity for intervention to align patient and surgeon expectations.

What Factors Are Associated With Revision Cubital Tunnel Release Within 3 Years?

“…It is unclear why these trends are seen. However, studies have reported that there are differences in the severity of cubital tunnel syndrome at the time of presentation by insurance type [3] as well as differences in patient expectations of the outcome of cubital tunnel release by insurance type [16], and these findings may affect postoperative outcomes. It is unclear why patients with workers compensation insurance may be at higher risk of revision surgery.…”
