Since AAPM Report No. 33 on Diagnostic Radiology Physics staffing is more than 20 years old, the Diagnostic Work and Workforce Study Subcommittee (DWWSS) of the Professional Council was formed to conduct a new study and update the data. The intent of the DWWSS study has two goals. First, it wanted to assess the number of FTE diagnostic physicists needed to support the QC, acceptance tests, radiation safety and other clinical functions for various imaging modalities, such as: CT scanners, MRI units, angiography rooms, ultrasound units, nuclear medicine imagers and other equipment. For example, the preliminary results indicate that the median annual physics support for one CT scanner is 0.007 FTE or 12.6 hours per unit. Second, the study wanted to provide an estimate of the cost of these physics services in terms of a fraction of a dollar per patient examination performed. For example, the cost for physics support of CT would be $0.27 for each CT procedure. This information would be similar to the Abt study conducted in Radiation Oncology. Radiation therapy physicists have utilized the Abt studies to generate re-imbursement for physics services and to justify financially the cost of their work efforts. Appropriate recognition for physics efforts in Diagnostic Radiology has never been properly quantified nor appreciated. With all the current and future changes occurring in healthcare, the information from the DWWSS survey could be important to the future of diagnostic physicists. Although diagnostic physicists are involved with many other activities such as teaching of residents and research, information about the clinical equipment support effort could be used to assess diagnostic physics staffing needs. The goals of the DWWSS study and the preliminary findings will be presented.
自美国医学物理师协会(AAPM)第33号关于诊断放射物理学人员配置的报告发布至今已有20多年,专业委员会的诊断工作与劳动力研究小组委员会(DWWSS)成立以开展一项新研究并更新数据。DWWSS研究的目的有两个。其一,它希望评估支持各种成像模态(如CT扫描仪、MRI设备、血管造影室、超声设备、核医学成像仪及其他设备)的质量控制、验收测试、辐射安全及其他临床功能所需的全职等效(FTE)诊断物理师数量。例如,初步结果表明,一台CT扫描仪每年的物理支持中位数为0.007 FTE或每台12.6小时。其二,该研究希望根据每次患者检查执行的物理服务成本,以美元的几分之一来估算这些物理服务的成本。例如,CT的物理支持成本为每次CT检查0.27美元。此信息类似于在放射肿瘤学中进行的Abt研究。放射治疗物理师利用Abt研究来获得物理服务的报销,并从财务上证明其工作成本的合理性。诊断放射学中对物理工作的适当认可从未得到过恰当的量化或重视。鉴于医疗保健领域当前和未来发生的所有变化,DWWSS调查的信息可能对诊断物理师的未来至关重要。尽管诊断物理师还参与许多其他活动,如住院医师教学和研究,但有关临床设备支持工作的信息可用于评估诊断物理师的人员配置需求。将介绍DWWSS研究的目标和初步结果。
