Comparing telemedicine and in-person gastrointestinal cancer genetic appointment outcomes during the COVID-19 pandemic

BACKGROUND: The study purpose is to compare outcomes associated with completion of genetic testing between telemedicine and in-person gastrointestinal cancer risk assessment appointments during the COVID-19 pandemic. METHODS: Data was collected on patients with scheduled appointments between July 2020 and June 2021 in a gastrointestinal cancer risk evaluation program (GI-CREP) that utilized both telemedicine and in-person visits throughout the COVID-19 pandemic, and a survey was administered. RESULTS: A total of 293 patients had a GI-CREP appointment scheduled and completion rates of in-person versus telemedicine appointments were similar. Individuals diagnosed with cancer and those with Medicaid insurance had lower rates of appointment completion. Although telehealth was the preferred visit modality, there were no differences in recommending genetic testing nor in the consent rate for genetic testing between in-person and telemedicine visits. However, of patients who consented for genetic testing, more than three times more patients seen via telemedicine did not complete genetic testing compared to those seen in-person (18.3% versus 5.2%, p = 0.008). Furthermore, telemedicine visits had a longer turnaround time for genetic test reporting (32 days versus 13 days, p < 0.001). CONCLUSIONS: Compared to in-person GI-CREP appointments, telemedicine was associated with lower rates of genetic testing completion, and longer turnaround time for results.
