Emergency and Acute Care Studies

Lung ultrasound examination has been suggested as a useful tool with which to detect lung involvement during the COVID-19 pandemic, desirable particularly for pregnant women1-3. We developed a specific single-day training program to provide gynecologists and obstetricians who are already skilled in ultrasound examination with the theoretical background required for recognition of normal and the main abnormal lung ultrasound patterns. The training program was developed at the Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy and University of Trento, Trento, Italy, and is available on a dedicated website (https://covid19.disi.unitn.it/iclusdb/login); to obtain access to the platform please send a request to [email protected]. The program design was presented to the COVID-19 Research Ethics Committee, who evaluated and approved the project (Prot. 1370/20, ID: 3067). In this study, we evaluated the feasibility and effectiveness of this rapid training program by providing it to a group of 11 trainees and comparing the number of correct classifications in their pre- and post-training results. The trainees were gynecologists and obstetricians who were skilled in obstetric and/or gynecological ultrasound examination, but with no experience in lung ultrasound; three of them had been involved for 1 week in meetings with pneumologists to prepare the recent publication on 'How to perform lung ultrasound in pregnant women with suspected COVID-19'4. The trainers were two pneumologists (A.S. and R.I.) and one pediatrician (D.B.), all of whom have more than 10 years of experience in lung ultrasound examination, in clinical practice as well as for the purposes of research and teaching. The training program consisted of three phases. Phase 1 consisted of a 15-min pretraining test, in which each of the 11 trainees was asked to assess 10 ultrasound videoclips, which had been obtained by one of four experts (G.S., R.C., A.S., R.I). Each videoclip showed a normal ultrasound pattern or one of five typical pathological patterns. After watching the videoclip, each trainee was asked to classify the pattern, choosing from among the following possibilities (Figure 1): (a) normal; (b) clear and distinct vertical artifacts with small pleural alterations (Score = 1) or broken pleural line and small consolidations (Score = 2); (c) white lung without evident subpleural consolidations (Score = 3); (d) white lung with evident subpleural consolidations (Score = 3); (e) pattern not compatible with COVID-19 pneumonia (massive consolidations); (f) pattern not compatible with COVID-19 pneumonia (pleural effusions)5. Phase 2 consisted of a 2-hour theoretical course, addressing clinical and ultrasound issues related to lung ultrasound imaging5. Phase 3 was a 15-min post-training test, in which the trainees had to reassess the 10 ultrasound videoclips, which were presented in a different order. The number of correct diagnoses (pre- and post-training) was recorded for each participant (Table S1). The median number of correct answers among the trainees was 6 (range, 2–10) at the pretraining test and 9 (range, 6–10) at the post-training test. All trainees initially achieving 100% correct answers remained at this level post-training, and all those initially achieving less than 100% improved after training, with the median difference in number of correct answers being + 2 (range, 0 to + 6). Looking more closely at the post-training classifications, eight of the 11 trainees correctly discriminated normal from pathological patterns in all cases, two did so in 90% of cases and one in 80% of cases. In conclusion, our preliminary experience suggests that a rapid teaching program is sufficient to provide gynecologists and obstetricians who are already skilled in obstetric and/or gynecological ultrasound examination with the theoretical skills necessary to recognize specific lung ultrasound patterns. We believe that our course represents one possible model for implementing lung ultrasound education and might be a useful launch-pad for gynecologists and obstetricians involved in the management of pregnant patients with confirmed or suspected COVID-19.
