Considerations for Radiation Safety Professionals to Prepare and Respond to the Next Pandemic.

ABSTRACT: The Health Physics Society's stated mission is "excellence in the science and practice of radiation safety." Why, then, should we discuss disease outbreaks, epidemics, and pandemics with radiation safety professionals? The answer is simple: all workers are impacted by infectious diseases-and, as safety professionals, we will inevitably be called upon to prepare for and respond to these events. The COVID-19 pandemic has disrupted every facet of life, including home, school, work, and leisure. Moreover, virtually all radiation safety professionals have been impacted by the pandemic either personally, academically, or professionally. Even if radiation safety professionals were not involved directly with COVID-19 response, they were impacted by school closures, remote schooling and work, testing regimes, temperature screenings, vaccination programs, and so forth. However, many radiation safety professionals have been intimately involved in COVID-19 response through activities such as the deployment of personal protective equipment, directional airflow verification for isolation areas, disinfection and decontamination efforts, the design and layout of testing and vaccine centers, and in many other ways. Yet, it is likely that many radiation safety professionals have not received formal training in epidemiology, disease control, or other related topics, and thus may not be attuned to the key aspects to consider when the next pandemic emerges-and it will.

[Reducing the impact of COVID-19 on radiation oncology units of developing countries: A rapid review and expert consensus]. / Reduciendo el impacto de COVID-19 sobre la radioterapia oncológica en países en desarrollo: revisión rápida y consenso de expertos.

OBJECTIVE: To generate recommendations on the management of radiotherapeutic treatments during the pandemic, adapted to a country with limited health resources. METHODS: We did a rapid review of the literature, searching for papers that describe any measures to reduce the risk of COVID-19 infection, as well as management guidelines to reduce the workload, in radiotherapy units. The following conditions were included in the scope of this review: gynecological tumors, breast cancer, gastrointestinal tumors, genitourinary tumors, head and neck tumors, skin cancer, tumors of the central nervous system, and lymphomas. An expert group discussed online the extracted data and drafted the recommendations. Using a modified Delphi method, the consensus was reached among 14 certificated radio-oncologists. The quality of the evidence that supported the recommendations on treatment schedules was assessed. RESULTS: A total of 57 documents were included. Of these, 25 provided strategies to reduce the risk of infection. Recommendations for each condiction were extracted from the remaining documents. The recommendations aim to establish specific parameters where treatments can be omitted, deferred, prioritized, and shortened. Treatment schemes are recommended for each condition, prioritizing hypo-fractionated schemes whenever possible. CONCLUSIONS: We propose strategies for the management of radiotherapy services to guarantee the continuity of high-quality treatments despite the health crisis caused by COVID-19.

OBJETIVO: Establecer recomendaciones para la toma de decisiones de manejo en radioterapia durante la pandemia de COVID-19, adaptadas a un país con recursos de salud limitados. MÉTODOS: A través de una revisión rápida de la literatura se buscaron publicaciones que describieran medidas para reducir el riesgo de infección por COVID-19, así como también pautas de manejo para reducir la carga de trabajo en las unidades de radioterapia. Se incluyeron en el alcance de esta revisión las siguientes patologías: tumores ginecológicos, cáncer de mama, tumores gastrointestinales, tumores genitourinarios, tumores de cabeza y cuello, cáncer de piel, tumores del sistema nervioso central y linfomas. Un grupo de expertos discutió en línea los datos extraídos y redactó las recomendaciones. Mediante un método Delphi modificado, se evaluó el consenso entre 14 radio-oncólogos certificados. Se evaluó la calidad de la evidencia que sustentó las recomendaciones sobre esquemas de tratamiento. RESULTADOS: Se incluyeron un total de 57 documentos. De 25 trabajos se extrajeron las estrategias para reducir el riesgo de infección. De los restantes, se obtuvieron las recomendaciones para cada patología. Las recomendaciones están orientadas a establecer escenarios específicos donde se pueden omitir, diferir, priorizar y acortar los tratamientos. En el ítem de acortar se recomiendan esquemas de tratamiento para cada patología, priorizando los esquemas hipofraccionados cuando fue posible. CONCLUSIÓN: Se plantean estrategias para la gestión de los servicios de radioterapia con el objetivo de garantizar que los tratamientos de alta calidad para pacientes oncológicos sigan entregándose, pese a la crisis sanitaria ocasionada por COVID-19.

Development and execution of a pandemic preparedness plan: Therapeutic medical physics and radiation dosimetry during the COVID-19 crisis.

The SARS-CoV-2 coronavirus pandemic has spread around the world including the United States. New York State has been hardest hit by the virus with over 380 000 citizens with confirmed COVID-19, the illness associated with the SARS-CoV-2 virus. At our institution, the medical physics and dosimetry group developed a pandemic preparedness plan to ensure continued operation of our service. Actions taken included launching remote access to clinical systems for all dosimetrists and physicists, establishing lines of communication among staff members, and altering coverage schedules to limit on-site presence and decrease risk of infection. The preparedness plan was activated March 23, 2020, and data were collected on treatment planning and chart checking efficiency for 6 weeks. External beam patient load decreased by 25% during the COVID-19 crisis, and special procedures were almost entirely eliminated excepting urgent stereotactic radiosurgery or brachytherapy. Efficiency of treatment planning and chart checking was slightly better than a comparable 6-week interval in 2019. This is most likely due to decreased patient load: Fewer plans to generate and more physicists available for checking without special procedure coverage. Physicists and dosimetrists completed a survey about their experience during the crisis and responded positively about the preparedness plan and their altered work arrangements, though technical problems and connectivity issues made the transition to remote work difficult. Overall, the medical physics and dosimetry group successfully maintained high-quality, efficient care while minimizing risk to the staff by minimizing on-site presence. Currently, the number of COVID-19 cases in our area is decreasing, but the preparedness plan has demonstrated efficacy, and we will be ready to activate the plan should COVID-19 return or an unknown virus manifest in the future.
