目的 分析床旁影像技术强化培训方式在重症医学进修医师教学中的应用效果。方法 采用试验对照方法。2020年1月至2023年5月,以北京协和医院重症医学科的全体进修医师为研究对象。其中,2021年10月至2023年5月入科的54名进修医师设为试验组,采用床旁影像技术强化培训方式;2020年1月至2021年9月入科的66名进修医师设为对照组,采用传统教学方式。通过两组进修医师的床旁影像技术考核成绩和获得独立值班资格人数评价教学效果。采用t检验、Mann-Whitney U检验和卡方检验进行数据分析。结果 试验组进修医师的肺部超声、心脏超声、电阻抗断层成像技术、旁流暗视野技术的考核通过率均高于对照组进修医师,分别为100.0%(54/54)比77.3%(51/66),100.0%(54/54)比71.2%(47/66),98.1%(53/54)比51.5%(34/66),18.5%(10/54)比3.0%(2/66),其差异均具有统计学意义(均P＜0.05)。试验组进修医师获得独立值班资格人数的比例高于对照组进修医师[25.9%(14/54)比6.1%(4/66)],其差异具有统计学意义(P=0.004)。结论 床旁影像技术强化培训方式有助于重症医学科进修医师对床旁影像技术的掌握和临床能力的提高。
Objective To analyze the effect of intensive training of Critical Bedside Visual Image Technologies (TBVT) for critical care refresher physicians. Methods A controlled trial method was used. From January 2020 to May 2023, all refresher physicians in the department of Critical Care Medicine of Peking Union Medical College Hospital were studied. Among them, 54 refresher physicians between October 2021 and May 2023 were selected as experiment group and adopted TBVT for teaching, while the other 66 refresher physicians from January 2020 to September 2021 were selected as the control group, using traditional teaching methods. The effect was evaluated through the bedside imaging technology assessment results and the number of physicians qualified for independent duty by the two groups of refresher physicians. T-test, Mann-Whitney U test and chi-square test were used for data analysis. Results The qualification rates of pulmonary ultrasound, cardiac ultrasound, electrical impedance tomography, and sidestream dark-field technology in the study group were higher than those in the control group [100.0%(54/54) vs. 77.3%(51/66), 100.0%(54/54) vs. 71.2%(47/66), 98.1%(53/54) vs. 51.5%(34/66), 18.5%(10/54) vs. 3.0%(2/66)], and the differences were statistically significant (all P<0.05). The proportion of physicians in the study group qualified for independent duty was higher than that of the control group [25.9%(14/54) vs. 6.1%(4/66)], and the difference was statistically significant (P=0.004). Conclusions The TBVT can help critical care refresher physicians better master bedside visual image techniques and improve clinical abilities.
