Impact of COVID-19 pandemic on thyroidectomy for malignant diseases in high-volume referral centers.

Abstract

The COVID-19 pandemic has limited the availability of healthcare resources for non-COVID patients and decreased elective surgeries, including thyroidectomy. Despite the prioritization of surgical procedures, it has been reported that thyroidectomy for thyroid cancer (TCa) was adversely impacted. We assessed the impact of the pandemic on the surgical activities of two high-volume referral centers. Patients operated at two National Referral Centers for Thyroid Surgery between 03/01/2020 and 02/28/2021 (COVID-19 period) were included (P-Group). The cohort was compared with patients operated at the same Centers between 03/01/2019 and 02/29/2020 (pre-COVID-19 pandemic) (C-Group). Overall, 7017 patients were included: 2782 in the P-Group and 4235 in the C-Group. The absolute number of patients with TCa was not significantly different between the two groups, while the rate of malignant disease was significantly higher in the P-Group (1103/2782 vs 1190/4235) (P < 0.0001). Significantly more patients in the P-Group had central (237/1103 vs 232/1190) and lateral (167/1103 vs 140/1190) neck node metastases (P = 0.001). Overall, the complications rate was significantly lower (11.9% vs 15.1%) and hospital stay was significantly shorter (1.7 ± 1.5 vs 1.9 ± 2.2days) in the P-Group (P < 0.05). The COVID-19 pandemic significantly decreased the overall number of thyroidectomies but did not affect the number of operations for TCa. Optimization of management protocols, due to limited resource availability for non-COVID patients, positively impacted the complication rate and hospital stay.
