Strategies to Maximize Available Resources With Minimum Cost Escalation for Improving Radiation Therapy Accessibility...

There is widespread accord among economists that the corona virus disease 2019 (COVID-19) pandemic will have a severe negative effect on the global economy. Establishing new radiation therapy (RT) infrastructure may be significantly compromised in the post-COVID-19 era. Alternative strategies are needed to improve the existing RT accessibility without significant cost escalation. The outcomes of these approaches on RT availability have been examined for Asia.

The details of RT infrastructures in 2020 for 51 countries in Asia were obtained from the Directory of Radiotherapy Centers of the International Atomic Energy Agency. Using the International Atomic Energy Agency guidelines, the percent of RT accessibility and the additional requirements of teletherapy (TRT) units were computed for these countries. To maximize the utilization of the existing RT facilities, 5 options were evaluated, namely, hypofractionation RT (HFRT) alone, with/without 25% or 50% additional working hours. The effect of these strategies on the percent of RT access and additional TRT unit requirements to achieve 100% RT access were estimated.

In 46 countries, 4617 TRT units are available. The mean percent of RT accessibility is 62.4% in 43 countries (TRT units = 4491) where the information on cancer incidence was also available, and these would need an additional 6474 TRT units for achieving 100% RT accessibility. By adopting HFRT alone, increasing the working hours by 25% alone, 25% with HFRT, 50% alone, and 50% with HFRT, the percent of RT access could improve to 74.9%, 78%, 90.5%, 93.7%, and 106.1%, respectively. Correspondingly, the need for additional TRT units would progressively decrease to 4646, 4284, 3073, 2820, and 1958 units.

The economic slowdown in the post-COVID-19 period could severely impend establishment of new RT facilities. Thus, maximal utilization of the available RT infrastructure with minimum additional costs could be possible by adopting HFRT with or without increased working hours to improve the RT coverage.
