PURPOSE: The Global Medical Physics Training and Development Program (GMPTDP) is a novel initiative that provides United States (US)-based graduate students in medical physics with structured, immersive clinical training in Ghana. METHODS: The five-week program begins with a cultural and clinical orientation in the US, followed by 4 weeks of clinical rotations across leading Ghanaian medical institutions. During rotations, students gain experience with teletherapy (LINACs and cobalt-60), brachytherapy, treatment planning, imaging, and more. Trainees participate in clinical activities, conduct collaborative projects, and engage in community outreach and cultural immersion. The program culminates in a symposium highlighting student experiences and future directions with speakers including physicists, oncologists, engineers, and policymakers. RESULTS: The pilot year of the program was successfully completed by three students from May 28 2024-July 2 2024. This article outlines the development, structure, and implementation of GMPTDP as a replicable model for global health training in medical physics, emphasizing sustainable partnerships between high-income and low- and middle-income countries. Educational objectives include demonstrating effective cross-border training models, fostering collaborative research, and expanding global clinical experience in the field of medical physics. CONCLUSIONS: A model for a global medical physics training program was developed and successfully implemented.

Purpose: Our purpose was to assess physics quality assurance (QA) practices in less resourced radiation therapy (RT) centers to improve quality of care. Methods and Materials: A preliminary study was conducted in 2020 of 13 select RT centers in 6 countries, and in 2021, our team conducted onsite visits to all the RT centers in Ghana, one of the countries from the initial survey. The RT centers included 1 private and 2 public institutions (denoted as Public-1 and Public-2). Follow-up surveys were sent to 17 medical physicists from the site visit. Questions centered on the topics of equipment, institutional practice, physics quality assurance, management, and safety practices. Qualitative and descriptive methods were used for data analysis. Questions regarding operational challenges (machine downtime, patient-related issues, power outages, and staffing) were asked on a 5-point Likert scale. Results: The preliminary survey from 2020 had a 92% response rate. One key result showed that for RT centers in lower gross national income per capita countries there was a direct correlation between QA needs and the gross national income per capita of the country. The needs identified included film/array detectors, independent dose calculation software, calibration of ion chambers, diodes, thermoluminiscence diodes (TLDs), phantoms for verification, Treatment Planning System (TPS) test phantoms, imaging test phantoms and film dosimeters, education, and training. For the post survey after the site visit in 2021, we received a 100% response rate. The private and the Public-1 institutions each have computed tomography simulators located in their RT center. The average daily patient external beam workload for each clinic on a linear accelerator was: private = 25, Public-1 = 55, Public-2 = 40. The Co-60 workload was: Public-1 = 45, Public-2 = 25 (there was no Co-60 at the private hospital). Public-1 and -2 lacked the equipment necessary to conform to best practices in Task Group reports (TG) 142 and 198. Public-2 reported significant operational challenges. Notably, Public-1 and -2 have peer review chart rounds, which are attended by clinical oncologists, medical physicists, physicians, and physics trainees. All 17 physicists who responded to the post site visit survey indicated they had a system of documenting, tracking, and trending patient-related safety incidents, but only 1 physicist reported using International Atomic Energy Agency Safety in Radiation Oncology. Conclusions: The preliminary study showed a direct correlation between QA needs and the development index of a country, and the follow-up survey examines operational and physics QA practices in the RT clinics in Ghana, one of the initial countries surveyed. This will form the basis of a planned continent-wide survey in Africa intended to spotlight QA practices in low- and middle-income countries, the challenges faced, and lessons learned to help understand the gaps and needs to support local physics QA and management programs. Audits during the site visit show education and training remain the most important needs in operating successful QA programs.
