    Abstract: Purpose The purpose of this study was two-fold: (1) To determine how the number of ultrasound scans a trainee has completed predicts the trainee’s diagnostic accuracy when performing transvaginal ultrasound examinations, and (2) to examine the utility of simulation-based assessment of ultrasound competence for determining readiness for independently performing examinations. Materials and Methods 101 OB/GYN trainees were surveyed regarding their clinical experience and the number of scans they had completed. All participants completed five different cases on a transvaginal virtual-reality ultrasound simulator (Scantrainer, Medaphor). The participants’ diagnostic accuracy was recorded and expert raters evaluated their performance using the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale. The utility of simulation-based assessments was assessed with respect to reliability, validity, acceptability, and costs. The main outcome was diagnostic accuracy for five different ultrasound cases. Results Although the number of scans was associated with diagnostic accuracy (p = 0.006), it was a poor predictor (AUC 0.69) of diagnostic accuracy. Only 56.6 % (n = 34) of participants who had more than 100 transvaginal scans demonstrated a diagnostic accuracy of 0.80 or above. The reliability of the OSAUS assessments was high (ICC 0.82) and the majority of participants supported the use of simulation-based assessments for future licensing exams (70.3 %). The running costs of simulation-based assessments (154 EUR per participant) were lower than for practical examinations using real patients. Conclusion The number of completed ultrasound scans was a poor predictor of the trainees’ diagnostic accuracy. Instead, simulation-based assessments can be used to ensure that trainees are ready for independently performing future scans.

    Abstract: There is no international consensus on the orientation of transvaginal ultrasound images and no evidence exists to support the superiority of one image orientation over the other. The aim of this study was to compare learning curves and skills transfer in a group of novices randomized to top‐down or bottom‐up image orientation, and to determine whether individual preferences for image orientation affect learning and skills transfer. Material and methods 60 senior medical students, with no prior ultrasound experience, were randomized to orient the image top‐down or bottom‐up during training on an ultrasound simulator until attaining expert levels of performance. Participants then completed a transfer test involving a systematic ultrasound examination on a physical mannequin using real ultrasound equipment. Performance was assessed during the transfer test by two independent raters using the objective structured assessment of ultrasound skills ( OSAUS ) score and a global rating score. Results The bottom‐up group reached the expert level with significantly fewer attempts than did the top‐down group [median ±  interquartile range : 4 ± 2 vs 5 ± 3] (U = 285.5, P  = 0.014). The bottom‐up group used less time to achieve the expert level (median ±  interquartile range : 3 h 2 m ± 1 h 14 m vs 3 h 28 m ± 2 h 21 m) (U = 301.5, P  = 0.029). The two groups performed similarly during the transfer test with respect to their OSAUS scores (top‐down 56.7% vs bottom‐up 53.2%, P  = 0.13). The global rating scores were higher in the top‐down group (top‐down 57.1% vs bottom‐up 50.0%, P  = 0.02). Conclusions Orientation of the images bottom‐up rather than top‐down, led to a steeper learning curve, but had little or no impact on the subsequent transfer of skills.

    Abstract: The objective of this study was to explore the association between detection of fetal growth restriction and maternal‐, healthcare provider‐ and organizational factors. Material and methods A historical, observational, multicentre study. All women who gave birth to a child with a birthweight 〈 2.3rd centile from 1 September 2012 to 31 August 2015 in Zealand, Denmark, were included. The population was identified through the Danish Fetal Medicine Database. Medical charts were reviewed to obtain data regarding maternal characteristics and information on the healthcare professionals. Date of authorization for the midwives and obstetricians involved was extracted from the Danish Health Authorization Registry. Multivariable Cox regression models were used to identify predictors of antenatal detection of fetal growth restriction, and analyses were adjusted for hospital, body mass index, parity, the presence of at least one risk factor and experience of the first midwife, number of midwife visits, number of visits to a doctor, the experience of the consultant midwife or the educational level of the doctor, the number of scans and gaps in continuity of midwife‐care. Antenatal detection was defined as an ultrasound estimated fetal weight 〈 2.3rd centile (corresponding to −2 standard deviations) prior to delivery. Results Among 78 544 pregnancies, 3069 (3.9%) had a fetal growth restriction. Detection occurred in 31% of fetal growth‐restricted pregnancies. Clinical experience (defined as years since graduation) of the first consultation midwife was positively associated with detection, with a hazard ratio [HR] of 1.15, 95% confidence interval [CI] 1.03‐1.28), for every 10 years of additional experience. The hazard of detection increased with the number of midwife consultations (HR 1.15, 95% CI 1.05‐1.26) and with multiparity (HR 1.28, 95% CI 1.03‐1.58). After adjusting for all covariates, an unexplained difference between hospitals ( P  = .01) remained. Conclusions The low‐risk nullipara may constitute an overlooked group of women at increased risk of antenatal non‐detection of fetal growth restriction. Being screened by experienced midwives during early pregnancy and having access to multiple midwife consultations may improve future diagnosis.

    Abstract: Objective The purpose of this systematic review and meta-analysis was to examine the effects of simulation-based ultrasound training (SIM-UT) in obstetrics and gynecology compared to non-SIM-UT on trainee learning, clinical performance, patient-relevant outcomes, and cost of training. Methods A systematic search was performed in June 2019 in PubMed, Embase, and Scopus using search terms for the topic and the intervention as well as certain MESH terms. Inclusion criteria were defined in accordance with the PICO question. Studies published in any language involving SIM-UT in obstetrics and gynecology compared to non-SIM-UT or no training were included. The outcomes included effects on health care provider learning and clinical performance, patient-relevant outcomes, and cost of training. Two authors evaluated the study quality with the MERSQI instrument and the Oxford Quality Scoring System. A meta-analysis was planned for the included randomized controlled trials. Results 15 studies were included, and 11 studies were eligible for meta-analysis. SIM-UT was significantly superior to clinical training only and theoretical teaching with standard mean differences (SMD) of 0.84 (0.08–1.61) and 1.20 (0.37–2.04), respectively. However, SIM-UT was not superior to live model training; SMD of 0.65 (–3.25–4.55). Of all studies included in the meta-analysis, 91 % favored SIM-UT over clinical training alone, theoretical teaching, or in some cases live model training. Conclusion In the field of obstetrics and gynecology, SIM-UT in addition to clinical training markedly improves trainee learning, clinical performance, as well as patient-perceived quality of care.
