Process Modeling of Ultrasound-guided Needle Placement Interventions

剧情简介。加拿大的医科大学正在向以能力为基础的医学教育（CBME）模式过渡。能力的获得需要实践，出于患者安全和学习者舒适的考虑，早期阶段的实践最好在模拟环境中进行。所有医生都需要展示的技能之一是超声引导针头放置（USNP），在手术中放置导管端口，麻醉注射。这些手术的主要目的是在超声显像下将针插入目标，同时保留周围组织。USNP是非常困难的，因为它需要同时掌握多种技能。虽然USNP是每个加拿大新医生的强制性技能，但几乎完全缺乏计算和工程方法和工具来支持医学教育者开发USNP的CBME计划。对USNP过程建模的研究极为缺乏，从而严重阻碍了医学教育者向CBME医学教育模式的强制性过渡。

Synopsis. Canadian medical universities are in the process of transitioning to a Competency- based Medical Education (CBME) model at all levels of training. Achievement of competence requires practice, and for reasons of patient safety and learner comfort, the early stages of practice are best done in a simulated environment. One of the skills that all medical doctors are required to demonstrate is ultrasound-guided needle placement (USNP), in procedures catheter port placement, anesthetic injections. The primary goal in these procedures is to insert a needle to target under ultrasound visualization, while sparing surrounding tissues. USNP is extremely difficult because it requires simultaneous mastery of multiple skillsets. While USNP is a mandatory skill for every new Canadian physician, there is a near complete lack of computing and engineering methodology and tools to support medical educators in the development of CBME programs for USNP. Research on the USNP process modeling is extremely scant, thus critically hindering medical educators in the mandatory transition to the CBME medical education model. Research program. We aspire to fill these blanks through four themes: i) generalized process model for describing USNP workflows, ii) methods for automatic segmentation of USNP workflows into elementary procedural steps, iii) framework for designing quantitative performance metrics and, iv) data management framework for secure archival and retrieval of computer-assisted USNP training information. Outcomes. The scientific contribution of the proposed program will be the development of formal analytical methodology and software tools that aims to support medical education researchers in creating CBME training programs. The societal outcome from the program is potentially significant; research that supports the development of CBME-compliant computer-assisted training systems will impact the competence of future medical doctors and as a result on the health of all Canadians. A least 20 HQP trained will be trained in engineering and computer science research.
