Background:
Outpatient thyroidectomy is increasingly favored, given evidence of safety and convenience for selected patients. However, the prevalence of same-day discharge is unclear. We aimed to evaluate temporal trends, hospital characteristics, and costs associated with same-day discharge after total thyroidectomy in an all-payer, multi-state cohort.
Methods:
We included patients aged ≥18 years who underwent a total thyroidectomy (2013-2019) using Healthcare Cost and Utilization Project data. Admission type was defined as same-day, overnight, or inpatient based on length of stay. Same-day patients were propensity-score matched 1:1 with overnight patients. Hospital characteristics and costs were compared in the matched cohort.
Results:
Among 86,187 patients who underwent total thyroidectomy, 16,743 (19.4%) cases were same-day, 59,778 (69.4%) were overnight, and 9,666 (11.2%) were inpatient. The proportion of patients who underwent same-day thyroidectomy increased from 14.8% to 20.8% over the study period (P < .001), whereas overnight admissions decreased from 72.9% to 68.8% (P < .001). In total, 9,571 same-day patients were matched to 9,571 overnight patients. Same-day patients had higher odds of treatment at a certified cancer center (odds ratio 1.77; 95% confidence interval 1.65-1.90), Accreditation Council for Graduate Medical Education-accredited teaching hospital (odds ratio 1.72; 95% confidence interval 1.61-1.85), and high-volume hospital (odds ratio 1.53; 95% confidence interval 1.42-1.65). Pairwise cost differences showed median savings of $974 (interquartile range -1,610 to 3,491) for same-day relative to overnight admission (P < .001).
Conclusion:
Although over two-thirds of patients are admitted overnight, same-day total thyroidectomy is increasingly performed. Same-day thyroidectomy may be a lower-cost option for selected patients, particularly in specialty centers with experience in thyroidectomy.
