Point-of-care ultrasound is recognized as a safe and valuable diagnostic tool for patient evaluation. Hospitalists are prime candidates for advancing the point-of-care ultrasound field given their crucial role in inpatient medicine. Despite this, there is a notable lack of evidence-based ultrasound training for hospitalists. Most research focuses on diagnostic accuracy rather than the training required to achieve it. This study aims to improve hospitalists' point-of-care ultrasound knowledge and skills through a hands-on skills practicum.
Four skill practicums were conducted with pre-course, post-course, and six-month evaluations and knowledge assessments.
The mean pre- vs. post-course knowledge assessment scores significantly improved, 41.7% vs. 75.9% (SD 16.1% and 12.7%, respectively, < 0.0001). The mean ultrasound skills confidence ratings on a 10-point Likert scale significantly increased post-course (2.60 ± 1.66 vs. 6.33 ± 1.63, < 0.0001), but decreased at six months (6.33 ± 1.63 vs. 4.10 ± 2.22, < 0.0001). The greatest limitations to usage pre-course and at six months were knowledge/skills and lack of machine access. While knowledge/skills decreased from pre-course (82.0%) as compared to six-months (64.3%), lack of machine access increased from pre-course (15.8%) to six-months (28.6%) ( = 0.28).
Hospitalists agree that point-of-care ultrasound has utility in the diagnostic and therapeutic management of patients, though the lack of training is a significant limitation. Our study demonstrated that a brief skills practicum significantly improves hospitalists' confidence and knowledge regarding ultrasound image acquisition and interpretation in the short term. Long-term confidence and usage wanes, which appears to be due to the lack of machine access.
即时超声检查被认为是一种用于患者评估的安全且有价值的诊断工具。鉴于住院医师在住院医疗中发挥的关键作用,他们是推动即时超声领域发展的主要人选。尽管如此,针对住院医师的循证超声培训明显不足。大多数研究关注诊断准确性,而非实现该准确性所需的培训。本研究旨在通过实践技能培训提高住院医师的即时超声知识和技能。
开展了四次技能培训,并进行课前、课后及六个月后的评估和知识测评。
课前与课后知识测评的平均分数显著提高,分别为41.7%和75.9%(标准差分别为16.1%和12.7%,<0.0001)。在10分制的李克特量表上,超声技能信心评级在课后显著提高(2.60±1.66对6.33±1.63,<0.0001),但在六个月后有所下降(6.33±1.63对4.10±2.22,<0.0001)。课前及六个月后使用的最大限制因素是知识/技能以及缺乏设备使用机会。与六个月后(64.3%)相比,课前知识/技能受限的比例有所下降(82.0%),而缺乏设备使用机会的比例则从课前的15.8%增至六个月后的28.6%(P=0.28)。
住院医师一致认为即时超声在患者的诊断和治疗管理中具有实用价值,尽管培训不足是一个重大限制。我们的研究表明,简短的技能培训能在短期内显著提高住院医师对超声图像采集和解读的信心及知识水平。长期来看,信心和使用率会下降,这似乎是由于缺乏设备使用机会所致。
