Critical care ultrasonography (CCUS) has become a daily diagnostic tool for intensivists. While the effective training measures for ultrasound novices are discussed widely, the best curriculum for the novices to retain a long-term proficiency is yet to be determined.
Critical care medicine fellows who underwent an introductory CCUS workshop were randomly allocated into the standard training (ST) or the intensive training (IT) group. The IT group received an 8-h training besides the standardized fellowship education that the ST group received. Participant improvement in CCUS proficiency tests (maximum score, 200) after a 6-month training intervention was compared between the groups. CCUS examinations performed in patient care were observed over 2 years.
Twenty-one fellows were allocated into the ST (n = 10) or the IT (n = 11) group. No statistically significant difference was observed in the median (interquartile range [IQR]) improvement in CCUS proficiency tests between the ST group and the IT group: 18 (3.8-38) versus 31 (21-46) (P = .09). Median (IQR) test scores were significantly higher in postintervention than preintervention for both groups: ST, 103 (87-116) versus 124 (111-143) (P = .02), and IT, 100 (87-113) versus 143 (121-149) (P < .01). Participating fellows performed 226 examinations over the 2 years of observation.
Fellows improved their CCUS proficiency significantly after 6-month training intervention. However, an additional 8-h training did not provide further benefits.
重症超声（CCUS）已成为重症监护医师的日常诊断工具。虽然广泛讨论了超声新手的有效培训措施，但尚未确定新手保持长期熟练程度的最佳课程。
接受 CCUS 入门研讨会的重症监护医学研究员被随机分配到标准培训（ST）或强化培训（IT）组。IT 组除了接受 ST 组接受的标准化研究员教育外，还接受了 8 小时的培训。比较两组在 6 个月培训干预后的 CCUS 熟练程度测试（最高得分为 200）的参与者改善情况。在 2 年内观察了在患者护理中进行的 CCUS 检查。
21 名研究员被分配到 ST（n = 10）或 IT（n = 11）组。ST 组和 IT 组在 CCUS 熟练程度测试中的中位数（四分位距 [IQR]）改善方面没有统计学上的显著差异：18（3.8-38）与 31（21-46）（P = 0.09）。两组的干预后中位数（IQR）测试分数均明显高于干预前：ST，103（87-116）与 124（111-143）（P = 0.02），IT，100（87-113）与 143（121-149）（P ＜ 0.01）。在 2 年的观察期间，参与的研究员进行了 226 次检查。
研究员在 6 个月的培训干预后，其 CCUS 熟练程度显著提高。然而，额外的 8 小时培训并没有带来进一步的好处。
