Targeted, Condensed Lung Ultrasound Training Program for Image Interpretation: A Prospective Multicenter Observational Study in Intensive Care Unit Professionals

Introduction: Standardized training in lung ultrasound is lacking. Given time constraints and challenges in accessing training, there is a need for condensed, focused training programs. This study aims to assess the effect of a targeted, condensed two hour training session on the competency of intensive care unit (ICU) healthcare professionals in interpreting lung ultrasound clips. Methods: This is a multicenter prospective study in ICU healthcare professionals from six centers. Subjects received a two hour lung ultrasound training: a lecture on principles and recognition of (patho)physiological patterns followed by hands-on training. Subjects competency was tested using twenty pre-recorded lung ultrasound clips before and after training. Retainment of knowledge was tested after six to twelve months in a subset of subjects. Subjects were deemed competent if they reached a test score ≥80%. Results: Sixty-six subjects (49% intensivist, 44% with no lung ultrasound experience) were included. 61 subjects (92%) reached the predetermined competency level after training. After the training, the highest percentage of subjects (n = 27, 97%) who reached the competency threshold were those with no prior experience in lung ultrasound. Post-test scores were significantly higher than pre-test scores (87%, 95% CI (86, 89) vs 76%, 95% CI (73, 79), p < 0.001) with a median improvement of 9, 95% CI (7, 11) percentage points. After six to twelve months all retested subjects (n = 12) maintained competency. Conclusion: A short two hour training program may be sufficient for ICU healthcare professionals to achieve competency in lung ultrasound interpretation, even for subjects with no prior lung ultrasound experience. Further studies are needed to validate these findings in different settings and assess competency in bedside ultrasound acquisition.
