This study assessed the educational impact of hybrid cardiac Point of Care Ultrasonography (POCUS) training in a community-based academic setting.
Internal Medicine and Medicine/Pediatrics residents across all post-graduate years (PGY) at a midwestern medical school under-took a structured hybrid (online and hands-on teaching) model of POCUS training. Anonymous surveys with Likert-type scale responses were administered before and after the curriculum. Questions were categorized into domains to assess the residents' interest in learning POCUS, their understanding of fundamental cardiac ultrasound (US) concepts, and their confidence in its application. The authors used Fisher's Exact and t-test, and estimated odds ratios to gauge the impact of the training to achieve net scores above 0 on each domain.
A total of 27 and 26 residents completed the pre-and post-training surveys, respectively. Experience with previous cardiac US use showed a positive skew. The training resulted in a significant increase in both, the understanding of the principles, and the residents' confidence in its application. These findings were most significant amongst PGY 2 and 3 residents. Post-training mean scores were similar across all domains for subgroups of PGY level and previous ultrasound experience.
Residents displayed greater understanding of the fundamental cardiac ultrasound concepts with improved confidence levels after implementing a structured hybrid teaching model for POCUS. Future studies with objective assessment tools are needed to gauge the clinical impact of POCUS and its adoption rate in clinical practice to guide a recommendation for its incorporation into the residency curriculum.
本研究评估了在社区学术环境中混合式心脏床旁超声检查（POCUS）培训的教育影响。
一所中西部医学院所有研究生阶段（PGY）的内科和内科/儿科住院医师参加了POCUS培训的结构化混合（在线和实践教学）模式。在课程前后进行了采用李克特量表式回答的匿名调查。问题被分为几个领域，以评估住院医师对学习POCUS的兴趣、对基本心脏超声（US）概念的理解以及对其应用的信心。作者使用费舍尔精确检验和t检验，并估计优势比，以衡量培训对在每个领域获得高于0的净分数的影响。
分别有27名和26名住院医师完成了培训前和培训后的调查。以前使用心脏超声的经验呈正偏态分布。培训使对原理的理解和住院医师对其应用的信心都有显著提高。这些发现在PGY 2和3级住院医师中最为显著。对于不同PGY水平和以前超声经验亚组，培训后的平均分数在所有领域都相似。
在实施POCUS结构化混合教学模式后，住院医师对基本心脏超声概念有了更深入的理解，信心水平也有所提高。需要使用客观评估工具进行进一步研究，以评估POCUS的临床影响及其在临床实践中的采用率，从而指导将其纳入住院医师课程的建议。
