“…Introduced some years ago into clinical practice, the use of 3D‐TVS allows the acquisition and storage of 3D volumes of structures of interest, which can then be assessed offline and used for teaching purposes. We hypothesized that the combined use of real‐time TVS and evaluation of 3D volumes offline could provide adequate training for TVS assessment of DIE in a relatively short period of time.…”

“…Results from multiple trainees are necessary to allow evaluation of the learning curve in a structured training program. Training programs have been proposed in other fields of gynecologic ultrasound, such as for the diagnosis of adnexal masses and congenital uterine anomalies, with promising results. However, to the best of our knowledge, no specific training program for assessing DIE by TVS has been proposed.…”

Objective To assess the learning curves of trainees during a structured offline/hands-on training program for the ultrasonographic diagnosis of deep infiltrating endometriosis (DIE).Methods Four trainees (all Ob/Gyn postgraduates with at least 5 years' experience in ultrasonography in obstetrics and gynecology, but with no experience of sonographic examination of DIE) participated in the study. They underwent a 2-week training program with a single trainer. Day 1 was devoted to theoretical issues and guided offline analysis of 10 three-dimensional ultrasound volumes. During the following days, four sessions of real-time sonographic examinations were performed in a DIE referral center ultrasound unit. In between these sessions, the trainees analyzed four datasets offline, each containing 25 volumes. At the end of each set, misinterpreted volumes were reassessed with the trainer. Presence or absence of DIE at surgery was considered the gold standard. The trainees' learning process was evaluated by learning-curve cumulative summation (LC-CUSUM) and the deviations of the trainees' level of performance at the control stage was assessed by CUSUM (standard CUSUM), for different locations of DIE. ResultsThe trainees reached competence after an average of 17 (range, 14-21) evaluations for bladder, 40 (range, 30-60) for rectosigmoid, 25 (range, 14-34) for forniceal, 44 (range, 25-66) for uterosacral ligament (USL) and 21 (range, 14-43) for rectovaginal septum (RVS) locations of DIE, and then kept the process under control, with error levels of less than 4.5% until the end of the test. The overall accuracy for each trainee in diagnosis of DIE at the different locations ranged from 0.91 to 0.98 for bladder DIE, from 0.80 to 0.94 for rectosigmoid DIE, from 0.90 to 0.94 for forniceal DIE, from 0.79 to 0.82 for USL DIE and from 0.89 to 0.98 for RVS DIE. ConclusionsThe suggested 2-week training program, based on a mixture of offline and live scanning sessions, is feasible and apparently provides effective training for the ultrasonographic diagnosis of DIE.

The focus of this prospective study was to evaluate whether experience and level of training improves and influences the accuracy of fetal weight prediction by ultrasound. At term fetal weight is an important component for decisions concerning delivery mode and timing of labor induction. In 204 singleton pregnancies at term fetal weight estimation by ultrasound was performed by three examiners of different levels of professional experience and education. Examiner 1 was a specialist experienced consultant. Examiner 2 was a resident in the 2 nd year, who had a structured supervised ultrasound training for six month and examiner 3 was a resident in the 2 nd year, who received no structured supervised ultrasound training. The results of this study clearly showed that experienced ultrasound examiners estimate fetal weights more accurately than unexperienced examiners. Additionally, there is an impact of the level of resident's training on the results. The professional, most experienced examiner 1 estimated fetal weight the most precise, followed by the trained examiner 2, who achieved more accurate weight estimation than examiner 3. We could show that an intensive supervised training of at least six months is adequate to improve the accuracy of weight estimation significantly. Obstetric ultrasound is getting increasingly important in daily maternal-fetal medicine. Thus, it is essential not only to develop effective training curricula for obstetric and gynecological residents, but also to implement a comprehensive supervised ultrasound training. The results could demonstrate that it seems justified to spent time and resources on residents training, in order to meet the increasing demands of modern obstetric medicine.

An implementation of the learning curve cumulative summation test to evaluate a practicum for endometrial cancer ultrasound staging

et al. 2023

View full text Add to dashboard Cite

The learning curve cumulative summation (LC-CUSUM) test is commonly used as a quantitative assessment of the individual learning process. This study aimed to evaluate the skill acquisition process for performing ultrasound staging of endometrial cancer using the LC-CUSUM test. Methods: Sixty-seven ultrasound examinations performed by two operators were evaluated using the LC-CUSUM test according to their rate of success or failure to correctly stage myometrial invasion, serosa involvement, and pelvic and para-aortic lymph node involvement. The reference standard was the pathologic result. After the learning phase, the cumulative summation (CUSUM) test was applied to assess performance maintenance. Results: The processes achieved satisfactory performance in the majority of the cases according to the established definitions. Operator 1 reached adequate performance within the 30th procedure for all the locations considered, while operator 2 performed fewer than 30 ultrasound examinations by the audit time. The CUSUM test confirmed that the target quality was preserved after the learning phase. Moreover, the ultrasound staging for endometrial cancer was highly accurate. Conclusion: Using the LC-CUSUM test made it possible to monitor the achievement and maintenance of a satisfactory performance quantitatively. The LC-CUSUM test could be a valuable instrument to survey diagnostic pathways in gynecological ultrasonography quantitatively.
