Background The COVID-19 pandemic drastically altered perioperative medical practice owing to safety concerns, postponing elective or nonemergent procedures, supply chain shortages, and reallocating perioperative staff to care for patients with COVID-19. However, the impact of the pandemic on the conduct on anesthesiology clinical research is unknown. Objective The primary objective was to quantify the magnitude of the COVID-19 pandemic’s impact on anesthesiology clinical research. Methods We performed a systematic search using ClinicalTrials.gov to identify clinical trials related to the practice of anesthesiology. We screened trials with status updates from January 1, 2020, through October 1, 2021, to capture trials potentially affected by the COVID-19 pandemic by the time of our search. Investigators screened for relevant studies and extracted trial characteristics along with the reason for discontinuation reported on the clinical trial registry. Results A total of 823 clinical trials met inclusion criteria, and 146 clinical trials were discontinued within the designated date range. In total, 24 (16.4%) of the 146 clinical trials were halted explicitly owing to the COVID-19 pandemic. A significant association existed between trial enrollment numbers and the likelihood of discontinuation due to the COVID-19 pandemic, as larger trials were more likely to be disrupted (z=–2.914, P=.004). Conclusions The COVID-19 pandemic is reportedly associated with the discontinuation of anesthesiology-related clinical trials. With the uncertain course of the COVID-19 pandemic, developing anesthesia trial protocols to help minimize social interaction and prevent premature trial disruption are imperative.
Importance The COVID-19 pandemic has impacted clinical research due to safety measures such as social distancing and lockdowns. However, developing treatments for COVID-19 relies on conducting clinical trials. Using telemedicine or virtual methods may support ongoing trials and limit the pandemic's impact on clinical research. Objective To examine the use of virtual methods among ongoing and discontinued COVID-19 clinical trials. Design In this cross-sectional analysis, we performed a systematic search of ClinicalTrials.gov for COVID-19 related trials registered since the pandemic began. In masked, duplicate fashion, authors extracted data from included studies, noting whether trialists reported using telecommunication, virtualization, or remote data collection to deliver interventions and monitor outcome measures. The authors also coded the use of virtual methods for recruitment, enrollment, or follow-up visits. Chi-square tests and Kruskal-Wallis tests were used to assess differences in the use of virtual methods between ongoing and discontinued studies and differences between intervention types. Results Our search returned 2549 clinical trials, of which 2383 were included. Of included studies, 2109 (88.5%) were ongoing and 274 (11.5%) were discontinued. Overall, 519 (24.6%) ongoing COVID-19 trials reported using virtual methods for trial conduct and 43 (15.7%) discontinued trials reported using virtual methods. There was a statistically significant difference in the rate of reporting virtual methods between discontinued and ongoing trials ( X 2 1 = 27.2, P < .001). Studies listed as Behavioral or Other were more likely to report using virtual methods for delivering interventions compared to other intervention types ( X 2 1 = 751.88, P < .001). Conclusions and relevance The COVID-19 pandemic has necessitated an unprecedented need for safe and efficient clinical trial conduct. Nearly a quarter of ongoing COVID-19 clinical trials in our sample reported using virtual methods for supporting trial progress. Ongoing trials were more likely to report virtual methods compared to discontinued trials. Developing strategies that allow for continuing trials during emergencies may limit trial disruption. Exploring and developing remote trial methods may continue to be valuable in light of emerging COVID-19 variants and may persist beyond the pandemic.
