Managing Thyroid Nodules in Qatar During the COVID19 Pandemic

Abstract

Background: The Coronavirus disease 2019 (COVID-19) pandemic impacted health care systems in all countries, including Qatar. Hamad Medical Corporation (HMC); In compliance with recommendations, suspended all non-urgent procedures, including thyroid fine needle aspiration biopsies (FNAB). Thyroid nodules are second most common cause of referral to HMC endocrine clinic. FNABs are gold standard to differentiate benign from malignant nodules.1- 2 Methods: Our approach includes a teleconsultation to obtain patient’s history and risk factors. Reviewing neck ultrasound (US), obtaining a calcitonin level if indicated, considering comorbidities associated with a high risk of COVID-19 morbidity and mortality.3 Results: We developed a pathway triaging thyroid (FNAB) to:1-Urgent: patients at higher risk of aggressive thyroid malignancy. Benefits of early detection and treatment outweigh the risk of COVID-19 exposure.4 FNAB should not be delayed.2-Semi-urgent: patients at low risk for COVID-19 and high suspicion thyroid nodules, but no evidence that early detection improves survival2, FNAB may be delayed up to 12 months.3-Non-urgent: patients with asymptomatic nodules that have low or intermediate suspicion US pattern.2 Also, includes nodules with ATA high suspicion US pattern in pregnant women and patients at high risk for COVID-19. The risks outweigh the benefits. FNAB should be delayed until outbreak is controlled.4 When urgent FNAB is indicated, safety of patients and medical staff needs to be addressed.5 We recommend testing patient for COVID-19 before FNAB, utilizing US guidance with rapid on-site adequacy evaluation in all cases. Cervical lymph node FNAB with TG washout should be done if indicated. The patient should wear a mask. All medical staff involved should wear personal protective equipment (PPE). The operator should wear N95 mask and face shield. The patient should be informed about cytopathology results via telemedicine. Conclusion: Triaging thyroid (FNAB) during the COVID-19 pandemic should be based on nodule characteristics and risk of COVID-19 morbidity and mortality. Our group recommends deferring FNAB for asymptomatic patients.4FNAB should not be delayed in selected patients who benefit from early detection and intervention.Table1: Triage of Thyroid fine needle aspiration biopsies (FNAB).
