While patient-level determinants of total thyroidectomy use have been well described, surgeon-level drivers of more extensive surgery are present and less well described. This survey sought to examine the associations between surgeons' operative recommendations, their beliefs about cancer, and their attitudes about medical maximizing-minimizing. A mixed-mode, cross-sectional survey was administered in September 2020 via mail and email to 222 thyroid surgeons identified in the Centers for Medicare & Medicaid Services Provider Utilization and Payment Physician and Other Practitioners dataset. Participants were asked their treatment recommendation for a healthy 45-year-old woman with a solitary 2.0-cm papillary thyroid cancer. Surgeons were assessed with the Brief Worry Scale and a validated, single-item measure of cancer-related worry. The Clinician Maximizer-Minimizer scale was used to assess the extent of medical care that physicians tend to favor with their patients. Participants were categorized into terciles based on their responses to the Maximizer-Minimizer scale. The highest scoring tercile ("Maximizers") was compared with the two lower terciles by Student's -tests, chi-square, ANOVA, and logistic regression. Of the 149 surgeons (response rate 67.1%), 34.9% recommended total thyroidectomy with or without central neck dissection (CND), and 65.1% recommended lobectomy. Overall, the medical Maximizer-Minimizer scale had an average score of 24.6 (SD 6.8). There were no differences between surgeons' age, race, annual thyroidectomy volume, or practice setting by their Maximizer-Minimizer classification. Participants who recommended total thyroidectomy with or without CND had significantly higher Maximizer-Minimizer scores than those recommending lobectomy (25.9 ± 7.2 vs. 23.8 ± 6.4, = 0.03). Those classified as maximizers also had more cancer-related worry on both the single-item and Brief Worry Scales ( = 0.02). On logistic regression controlling for age, sex, race, specialty training, practice setting, and annual thyroidectomy volume, maximizers were still more likely to recommend total thyroidectomy with or without a CND (OR 2.4, [CI 1.01-5.55], = 0.047). Medical maximizing-minimizing tendencies represent one of potentially many unmeasured surgeon characteristics that may explain persistent patterns of over-diagnosis, over-treatment, and over-screening. Surgeons may benefit from awareness of how their own tendencies influence their surgical recommendations in patients with low-risk thyroid cancer.
