Objective During the coronavirus disease 2019 pandemic, ENT-UK recommended a move from face-to-face clinics to telephone appointments. This study reviewed the safety of telephone clinics for urgent two-week-wait cancer referrals. Methods Patients consulted in telephone clinics between April and November 2020 were identified from an electronic database. Study patients included those diagnosed with malignant disease at six months. The Head and Neck Cancer Risk Calculator version 2 score, outcome of the initial clinic and final diagnoses were reviewed. Results A total of 1062 patients were triaged in clinic; 9.2 per cent (n = 98) were diagnosed with cancer at 6 months. Of these 98 patients, 69 received an urgent face-to-face appointment, 26 underwent urgent scans and 3 had a delayed telephone review. Twenty patients (20.4 per cent) diagnosed with cancer had a low-risk Head and Neck Cancer Risk Calculator score. Conclusion The late diagnosis rate of 0.28 per cent suggests a small proportion of cancer could have been missed. Telephone clinics, whilst a pragmatic means to maintain patient flow during the pandemic, could result in late diagnoses.

Key Points 1. During the COVID-19 pandemic, NHS cancer referral guidance recommended a move from face-to-face clinics to telephone appointment. In this study, we reviewed the safety of telephone clinic for urgent 2-week wait cancer referrals. 2. In the 7 months study period during the COVID-19 pandemic, 1062 urgent 2-week wait cancer referrals were received in our regional head and neck specialist unit, reflecting a 7.3% decline compared to pre-pandemic data. 3. At 6-months follow-up, 98 (9.2%) patients received a new diagnosis of malignancy. 95 of them received their diagnoses promptly after their initial telephone clinic, whereas 3 patients received a delayed diagnosis. 4. There is a late diagnosis rate of 0.28% but we discussed in our cases that late diagnosis does not inevitably lead to worse clinical outcome or harm. 5. Telephone clinics will likely remain in some capacity after the pandemic, while telephone clinics are pragmatic means to maintain patient flow during the pandemic, they could result in risk of late diagnosis.
