Purpose: To describe and the effects of the Covid-19 pandemic on anthropomorphic phantom mailings and credentialing status inquiries (CSI).

Methods: IROC Houston provides many services and quality control programs to support institutions that participate in clinical trials, including OSLD output checks, credentialing, and anthropomorphic phantom end-to-end remote audits. The phantoms are used for credentialing for NCI sponsored clinical trials as well as standard QA purposes. The CSI forms are submitted by institutions wishing to be credentialed for multi-institutional clinical trials. Phantom shipment numbers from 2019 and 2020 were compared to determine the effect that the pandemic had on the number of NCI credentialing phantoms and QA phantoms mailed. CSI numbers were also compared to determine the impact seen in credentialing requests.

Results: 657 phantoms were shipped in 2019 and 623 phantoms were shipped in 2020. Overall, QA phantoms decreased by 77 and NCI phantom requests increased by 43 creating an overall decrease of 34 (5%) phantoms. A total of 4075 and 3744 CSI requests were completed in 2019 and 2020 respectively producing a decrease of 331 (8%) submissions.

Conclusion: Though the overall number of phantoms shipped was less in 2020 than it was in 2019, it was not substantially less and was within the fluctuation that we typically see year to year. The CSI numbers dropped in March, April and May and then increased in the summer. This is likely due to many institutions stopping clinical trials temporarily when Covid-19 was first spreading in the United States. As institutions implemented safety protocols, they were able to reopen clinical trials and we saw requests likewise increased.
