BackgroundIn an attempt to reduce interruptions in radiation treatment, our department implemented universal SARS-CoV-2 PCR testing during the peak of the New York City COVID-19 epidemic.MethodsStarting 4/18/20, outpatients coming into the Department of Radiation Oncology for either simulation or brachytherapy were required to undergo PCR testing for SARS-CoV-2. Starting on 5/6/20, patients were offered simultaneous SARS CoV-2 IgG antibody testing.ResultsBetween 4/18/20-6/25/20, 1360 patients underwent 1,401 outpatient screening visits (Table 1). Of the patients screened, 411 were screened between 4/18/20 and 5/6/20 (Phase 1) with PCR testing: 13 (3.1%) patients were PCR positive. From 5/7/20 to 6/25/20, 990 patients were scheduled for both PCR and antibody testing (Phase 2), including 41 previously screened in Phase 1. Of those with known antibody status (n=952), 5.5% were seropositive. After 5/21/20, no screened patient (n=605) tested PCR positive. In the month prior to screening (3/17/20-4/19/20), 24 of 625 patients initiating external radiation had treatment interrupted due to COVID-19 infection (3.8%) vs 7 of 600 patients (1.1%) in the month post screening (4/20/20-5/24/20) (p=0.002).ConclusionsState-wide mitigation efforts, coupled with intensive departmental screening, helped prevent interruptions in radiation during the COVID-19 epidemic that could have compromised treatment efficacy. |
