Purpose: Outcomes following carpal tunnel release (CTR) are generally favorable. When patient satisfaction or symptom resolution is not as expected, understanding what factors contribute to that outcome could allow for strategies targeted at improving results. Our purpose was to determine if measurable mental health factors, specifically resilience and pain catastrophization, correlate with patients' postoperative outcomes following CTR.
Methods: A prospective cohort study was performed. Ninety-four patients were recruited to take part in the study. Patients completed written consent, the Boston Carpal Tunnel Questionnaire (BCTQ), the Pain Catastrophizing Scale, and the Brief Resilience Scale. A single surgeon, or his resident under supervision, performed an open CTR under local anesthetic. Our primary outcome measure was a repeat BCTQ at 6 months. Pearson correlation coefficients and univariate analyses were performed to assess the correlation between Pain Catastrophizing Scale and Brief Resilience Scale scores and final BCTQ scores.
Results: Forty-three and 63 participants completed the BCTQ at 3 and 6 months, respectively. This was 10% below the number needed to achieve appropriate power. Among those that responded, all participants showed improvement in their symptoms (P = .001). There was no correlation between patients' Pain Catastrophizing Scale or Brief Resilience Scale scores and 6-month BCTQ scores or the amount of improvement in the BCTQ at final follow-up.
Conclusions: Most participants improved following CTR. Patients' self-assessed resilience, and the degree of pain catastrophization did no correlate with the amount of improvement patients had after surgery.
Type of study/level of evidence: Prognostic II.
