Prior to its use in the clinic, it requires an extensive validation procedure in which established clinical plans and those generated by the model are compared. The manual iterative nature of this process is resource intensive, as numerous iterations are required to fine-tune and optimize a RapidPlan model. To streamline the efficiency and reduce the resource burden of RapidPlan model validation, a standalone executable auto planning script was written in C# leveraging the Eclipse scripting application programming interface (ESAPI). The script automatically batch generates treatment plans, as well as exports and plots the population-based DVH metrics of these plans, without any user input, reducing the time and effort required to explore and refine model objectives. Configured with adjustable parameters via Excel and .txt files, this approach allows end users to change input variables quickly and easily without needing to re-approve the script. The script has been implemented for a variety of treatment sites, including intact prostate, prostate &amp; nodes, lung, rectum, unilateral head &amp; neck, bilateral head &amp; neck, and liver stereotactic body radiation therapy (SBRT). The process for liver SBRT has been used here as an example to illustrate the use and power of the script. Over numerous iterations, 76 patients in the model set and 17 patients in a validation set were replanned using the script, creating a total of 405 automatic plans with an overall active planning time of 118.7 h. This study demonstrates the effectiveness of automating the RapidPlan model validation process, significantly reducing the time and resource burden associated with traditional manual methods.</p>","PeriodicalId":14989,"journal":{"name":"Journal of Applied Clinical Medical Physics","volume":"26 7","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/acm2.70120","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143965504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are limited formal assessments of factors contributing to physicists well-being. Nine medical physicists at a US academic medical center were surveyed on 21 workplace factors, drawn from the National Academy of Medicine's systems model of clinician burnout and professional well-being between May 2022 and August 2022. Highly rated factors were summarized and presented to medical physicists in focus groups. Contextual inquiries (a form of shadowing) were conducted to gather additional information about factors contributing to well-being. Qualitative data from the survey, focus groups, and contextual inquiries were used to generate an affinity model, which medical physicists then validated and used to prioritize top factors. Twenty-two medical physicists at the academic medical center and three other US academic medical centers rated these factors by level of impact and level of effort, and improvement recommendations were made based on these results. Key factors affecting medical physicist well-being included inadequate staffing, work-life integration, excessive workload, and time pressure. Twenty-two medical physicists across four institutions prioritized the following top factors for improvement: (i) retain the hybrid work model, (ii) hire additional medical physicists to cover clinic responsibilities, (iii) limit or compensate after hours work, (iv) improve scheduling workflows, and (v) improve communication and visibility from organization-level leadership and administration. High impact, low effort priorities to improve medical physicist well-being across the four institutions include work-life integration, scheduling workflows, and relationships with leadership. These factors seem to be within the improvement control of each radiation oncology center.
