A Single-Center Audit of Symptomatic Breast Cancer Patient Referrals During COVID-19 Pandemic Restrictions

Background Recommendations to balance cancer care with patient and hospital staff safety have been issued to hospitals during the coronavirus disease (COVID-19) pandemic. Concerns have been raised that service restrictions could jeopardize effective cancer management. Thus, this study aimed to conduct an audit to verify this proposition. Methods We conducted an audit comparing two-week wait (2ww) breast cancer referrals in our center between May and July 2019 and 2020. The primary endpoints were changes in the overall referral rates, differences in the waiting time, and breast cancer diagnosis rates between the two cohorts. Group differences were evaluated using the chi-square test (χ(2)). A p-value of <0.05 at 95% CI was considered significant. Results The 2ww referrals decreased by 442 (28.3%) in 2020 (2019 N=1564 vs. 2020, N=1122). Referrals in 2020 were associated with a higher rate of two-week specialist consultation than referrals in 2019 (p<0.05). The 2020 patient cohort was associated with a higher rate of breast cancer diagnosis than the 2019 cohort (6.9% vs. 4.9%, p<0.05). Of the 521 patients who had telephone consultations, 29.2% were discharged, and 367 (70.4%) had post-telephone one-stop clinic visits, of which 9.0% had breast cancer. Conclusions The audit provided evidence of effective breast cancer services during the COVID-19 pandemic restrictions. The study results could inform patients and the general public at large that the waiting time and breast cancer diagnosis are not compromised during COVID-19 pandemic management. The high rates of post-telephone one-stop clinic visits and cancer diagnosis may indicate weakness in triage and difficulties in diagnosing nonspecific presentation of cancer over the telephone.
