Utilidad de una unidad de diagnóstico rápido durante la pandemia por SARS-CoV-2 para el diagnóstico de cáncer

Abstract

ObjectivesTo analyse changes in health care activity, time of referral and diagnosis intervals and the incidence of cancer during the first 2years of the SARS-CoV-2 pandemic in a quick diagnosis unit. Materials and methodsA retrospective observational study was carried out during the prepandemic year (March 1, 2019 to February 29, 2020) and the first 2years of the pandemic (March 1, 2020 to February 28, 2022). Demographic and clinical variables, the first visit interval, the diagnosis interval and the first visit-diagnosis interval were evaluated and compared. ResultsDuring the first pandemic wave, there was a reduction in referrals (−32.6%), which then increased 8.1% and 17.7% from the second wave until the end of the first pandemic year and the second pandemic year, respectively. An increase in referrals to primary care and a decrease in emergencies were identified. The increase in cancer diagnoses of 2.7% and 15.7% in the 2years of the pandemic was proportional to the increase in referrals. No changes were observed in benign processes or in cancer locations and stages. The first visit interval was higher for benign diseases (p < 0.0001). A prolongation of the diagnosis interval was observed in cancer patients, although during the 3years of the study the median was <15 days. ConclusionsThe impact of the pandemic affected the length of intervals and the origins of referrals. The quick diagnosis units constitute and urgent complementary cancer diagnostic route with a high diagnosis yield.
