How Useful is COVID-19 Antibody Testing - A Current Assessment for Oncologists.

ABSTRACT: The coronavirus disease 2019 (COVID-19) pandemic due to infection by a new human coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has seriously disrupted the provision of oncology services and their uptake. Antibody testing, both at an individual level and of populations, has been widely viewed to be a key activity for guiding the options for treatment of high-risk individuals, as well as the implementation of safe control of infection measures. Ideally, the detection of a specific antibody should signify that all individuals tested have been infected by SARS-CoV-2 and that in the case of specific IgG that they are immune to further infection. This would enable SARS-CoV-2-infected individuals to be appropriately managed and healthcare workers shown to be immune to return to work where they would no longer pose a risk to their patients or be at risk themselves. Unfortunately, this is not the case for COVID-19, where it has been shown that immunity may not be protective, and seroconversion delayed or absent. The variability in antibody test performance, particularly that of lateral flow assays, has caused confusion for the public and healthcare professions alike. Many antibody test devices have been made available without independent evaluations and these may lack both adequate sensitivity and specificity. This review seeks to educate healthcare workers, particularly those working in oncology, of the current benefits and limitations of SARS-CoV-2 antibody testing.

Project description:PurposeDuring the COVID-19 pandemic, telemedicine became an attractive alternative to in-person appointments. The role of telemedicine in patients who undergo frequent on-site treatment, such as radiation therapy, is unclear. The purpose of this study was to examine telemedicine use, physician satisfaction, and barriers to continued use in radiation oncology.Methods and materialsAn anonymous, electronic survey was distributed to radiation oncologists internationally between June and October 2020. Respondents described demographic and practice characteristics, and a 5-point Likert scale assessed provider satisfaction, ease of use, and overall utility of telemedicine. Analyses include descriptive statistics and subgroup comparisons using the χ2 test and Fisher's exact test.ResultsThe response rate was 4.3%. Two hundred thirty-two respondents completed the survey, 63.8% of whom were male, 52.6% aged 50 or younger, and 78.0% from the United States. Only 14.2% used telemedicine previously, which increased to 93.1% during COVID-19. Among all telemedicine users, usage rates were 77.9% for initial consultations, 97.2% for follow-up visits, and 35.9% for on-treatment visits. Of the respondents, 69.8% reported that <25% of patients requiring treatment experienced delays due to COVID-19. Most conducted appointments from the workplace, with 40.1% also doing so from home. Satisfaction was high at 73.8%, perceived usefulness was 76.9%, and 81.5% hope to continue using telemedicine after the pandemic. However, 82.4% had concerns with the inability to examine patients and 63.0% had concerns about poor patient access to the required technology. In addition, 49.5% had concerns regarding continued billing/reimbursement, less commonly at government centers (18.8%) compared with academic/satellite facilities (52.7%) and free-standing centers/community hospitals (50.7%, P = .039 for both comparisons). These concerns were also significantly higher among US physicians (53.2% vs 34.9%, P = .048).ConclusionsWidespread adoption of telemedicine by radiation oncologists occurred during COVID-19 with high rates of satisfaction and interest in continued use. Sustained reimbursement for telemedicine services is a significant concern, particularly in the United States and outside of government facilities.
