Simulated data-driven hospital selection for surgical treatment of well-differentiated thyroid cancer in older adults

Background: Thyroid surgery at high-quality hospitals is associated with fewer complications. We evaluated the impact of referring older adults with thyroid cancer to higher-performing local hospitals.Methods: We performed a simulation study of Surveillance, Epidemiology, and End Results-Medicare patients, aged >= 66 years, who underwent a thyroidectomy for well-differentiated thyroid cancer (2013-2017). An 80% sample was used to calculate each hospital's risk-standardized 30-day serious adverse event rate, dividing hospitals into quartiles by performance. Hospitals located <= 30 miles of the remaining 20% of patients were compared, and 30-day serious adverse event rates and costs were simulated as if patients were treated at higher-quality hospitals using logistic regression with each alternative hospital's fixed-effect.Results: We identified 8,946 patients who underwent thyroid resection at 843 hospitals. Average risk-adjusted serious adverse event rates ranged from 13.9% to 52.9% between quartile 1 and 4 hospitals (P < .001). We identified higher-quality hospitals for 43.7% of patients. Simulating care at the best local hospital reduced predicted serious adverse event rates from 25.6% (95% confidence interval, 24.7-26.4) to 16.2% (95% confidence interval, 15.5-16.8; P < .001), while modestly lowering average costs from $12,883 (95% confi-dence interval, 12,500-13,267) to $12,679 (95% confidence interval, 12,304-13,056; P=.029).Conclusion: Simulated care at higher-performing hospitals decreased serious adverse event rates after thyroid resection. Optimizing hospital selection may reduce postoperative morbidity without compro-mising preferences for local treatment.(c) 2022 Elsevier Inc. All rights reserved.

Automated summary

The study evaluated the impact of referring older adults with thyroid cancer to higher-quality hospitals for surgery. It was found that referral to higher-quality hospitals resulted in a lower rate of postoperative complications.
