MATERIALS/METHODS: Participants interested in a 12-week virtual training program completed a needs assessment survey via a data collection web application. The survey included demographics, practice characteristics, and interests in contouring and plan evaluation education and training. Herein we provide descriptive statistics of the reports from participant surveys.
RESULTS: Across Thailand, Myanmar, Malaysia, Indonesia, and Nepal, 116 participants (82 attendings, 33 residents, 1 other) responded from 23 participating medical institutions (20 public, 3 private). The average number of radiation oncologists per medical institution was 6.81 (range 1-30) and radiation oncology residents was 17.50 (range 2-56). In the 7 centers with residency programs, 0 (0%) indicated that residents were solely involved in contouring, 5 (71.4%) that residents were jointly involved in contouring with attendings, and 2 (28.6%) that attendings contour without residents. Commonly cited obstacles to providing radiotherapy included: patient financial barriers (61.4%), inadequate training (51.8%), too many patients (48.2%), lack of modern equipment (40.4%), shortage of staff (39.5%), and malfunctioning equipment (36.8%). The most common, top-rated obstacle was inadequate training (24.8%). The most seen disease sites were head and neck (38.2%) and breast (30.3%). Respondent time spent contouring the target was greatest for head and neck, pediatric, and lymphoma disease sites with 66 (56.9%), 59 (50.8%), and 46 (29.3%) indicating more than 1 hour, respectively. Respondent time spent contouring the normal tissues was greatest for head and neck, pediatric, and CNS disease sites with 51 (44%), 46 (39.7%), and 30 (26.1%) indicating more than 1 hour. For head and neck cases, 34 (29.3%) respondents typically contour 6-10 Organs at Risk (OARs), 47 (40.5%) contour 11-15 OARs, 18 (15.5%) contour 16-20 OARs, and 15 (12.9%) contour > 20 OARs. 85 (76.3%) respondents believe their practice would most benefit from head and neck contouring education, while 114 (98.3%) were interested in receiving contouring and plan evaluation training.
CONCLUSION: The biggest physician-reported obstacle to providing radiotherapy in Southeast Asian practices is inadequate training. There is both high need and interest for well-developed virtual training, particularly in head and neck contouring, which currently appears time-intensive and heterogeneous among practices.
