In March 2020, the World Health Organization declared the coronavirus outbreak a global pandemic. 1 Since then, countries worldwide have taken unprecedented measures in response to the outbreak and its demand on healthcare resources. One strategy has been delaying non-urgent surgery-one example being surgery for low-risk thyroid cancer. However, there are currently no data to inform how clinicians discuss and manage delayed treatment due to reasons beyond their own or the patients' control or decision-making. 2 During the pandemic, patients with lower risk thyroid cancer may have had to 'sit' with knowledge of their cancer for a prolonged period of time while awaiting surgery. For patients with higher risk cancers, surgical treatments including completion thyroidectomy, radioactive iodine (RAI) therapy and use of systemic therapies may also have been delayed. The aim of this study was to quantitatively examine the views and experiences of clinicians managing patients with thyroid cancer before and during the COVID-19 pandemic.

The study recruited thyroid cancer surgeons and endocrinologists who managed patients during the COVID-19 pandemic with ethics approval from the University of Sydney. Clinicians were invited to participate through email from the membership of the Australian New Zealand Endocrine Surgeons; Endocrine Society of Australia; Australian Society of Otolaryngology, Head and Neck Surgery; Asian Association of Endocrine Surgeons; and The American Thyroid Association. Data were collected between July and November 2020. The survey was administered through the online platform Qualtrics and took <10 min to complete. Quantitative analyses were carried out using Stata/IC v16 (StataCorp LP, USA). Descriptive statistics summarised the sample characteristics and the proportion of clinicians endorsing items on types of treatments delayed, worry about delays in treatment, and confidence in discussing delays in treatment. Multivariable linear regression models were used to examine the association of demographic and clinical practice characteristics with comfort delaying treatment generally, and specifically during the COVID-19 pandemic (controlling for comfort in general). Two-tailed p-values less than .05 were considered statistically significant.

Of 269 clinicians who consented and began the survey, 199 completed it and were included in the analysis ( Table 1 ). The main treatment clinicians reported being delayed during the COVID-19 pandemic was thyroidectomy (n = 114; 57.3%), followed by surveillance imaging (n = 100; 50.3%), hemi-thyroidectomy (n = 92; 46.2%), adjuvant RAI (n = 87; 43.7%), therapeutic RAI for metastatic or recurrent disease (n = 40; 20.1%) and systemic therapies (n = 14; 7.0%). Only 10.6% (n = 21) of clinicians reported not delaying any treatments. The majority of these (n = 12; 57.1%) were from Australia and New Zealand.

For all types of thyroid cancer, when asked on a 5-point Likert scale (from very much to not at all) whether clinicians were 'worried about having to delay treatment for their patients' during the COVID-19 pandemic, 48 (24.1%) reported being very much or quite a bit worried, 127 (63.8%) reported being somewhat or a little bit worried and 24 (12.1%) reported being not at all worried. The most common reported reason for clinician worry was patient anxiety (n = 54; 27.1%). Only 27 clinicians (13.6%) reported they were themselves worried about disease progression and seven clinicians (3.5%) reported worry that their patient may need more invasive treatments after treatment delay. Practice and financial implications were mentioned only by seven (3.5%) and three (1.5%) clinicians, respectively. Focusing on low-risk thyroid cancer, in general (not during the COVID-19 pandemic), 72.9% (n = 145) of clinicians reported being very or quite comfortable (on a 5-point Likert scale) delaying surgery or other treatments for patients. Table 2 outlines the reasons clinicians gave for their level of comfort. Mean scores for level of comfort (not comfortable at all to very comfortable, scale 0-10) about delaying surgery or other treatments for patients with lowrisk thyroid cancer, and now (during the COVID-19 pandemic), were 6.60 (SD 2.62) and 6.61 (SD 2.60), respectively. Level of comfort delaying in general, and delaying now, were extremely positively correlated (r 198 = 0.91, p < 0.001). Clinicians' comfort with delaying treatment differed by region of practice (p < 0.0001) and clinical specialty (p = 0.0002) with greater comfort reported in North/South America and by endocrinologists compared to surgeons (Table S1) .

While this survey only provides a snapshot of thyroid clinicians' views and experiences regarding delayed treatment, specifically surgery, it demonstrates that worry was not excessive and may indicate a growing appreciation of the shift towards active surveillance for those with low-risk thyroid cancer. We found clinicians were most worried about patient anxiety, with only a small proportion of clinicians being worried about the risk of disease progression and the need for more invasive treatments. This suggests that while clinicians understand thyroid cancer biology, some still find it difficult to explain this to patients, or feel patients will find it difficult to accept. 3, 4 Although temporarily delaying treatment is different to management through active surveillance, these internationally based findings provide insights into how clinicians offer treatment choices for thyroid cancer. It will be of interest to see if treatment delays and clinician experience with delays related to the pandemic alter patient management choices and patient-reported concerns, and affect attitudes to treatment in the future. Response options were provided, and clinicians could choose more than one response.
