Objective: The aim of the study was to evaluate patterns of skill acquisition in the labor cervical examination in novice providers, such as the change in accuracy and overestimation and underestimation over time and the impact of dilation and effacement on accuracy., Methods: In this descriptive longitudinal study, medical students each performed 120 simulated cervical examinations. Accuracy and how often students overestimated and underestimated dilation and effacement during was determined for each set of 10 repetitions. Accuracy data were grouped and compared by dilation (1-3, 4-6, and 7-10 cm) and effacement (90%, 75%, 50%, and 25%)., Results: Student accuracy in dilation significantly improved throughout the course of the study (P < 0.001). At the beginning of the study, students more often overestimated dilation, but this decreased over time (P < 0.001). In addition, the accuracy of the students' estimations was 84%, 62%, and 52% for dilations of 1-3, 4-6, and 7-10 cm, respectively (P < 0.001). Student accuracy in effacement significantly improved throughout the course of the study (P < 0.001). At the beginning of the study, students more often overestimated effacement, but as training progressed, more students tended to overestimate and underestimate equally often (P < 0.001). In addition, accuracy of the students' estimations was 93%, 88%, 81%, and 35% for effacements of 90%, 75%, 50%, and 25%, respectively (P < 0.001)., Conclusions: Knowing that students tend to overestimate cervical dilation and effacement early in training and that cervices of high dilation and low effacement are more difficult to assess will be helpful in designing more efficient cervical examination training regimens.

Introduction: To assess how skill in the digital cervical examination is acquired in medical students., Methods: In a longitudinal study, medical students completed 200 simulated cervical examinations. We performed regressions of each student's cumulative accuracy using the linear, power, and sigmoidal models to determine best fit. We also constructed multilevel models to determine the influence of dilation and effacement on accuracy and to determine whether the starting level and rate of learning varied between individuals. To assess skill decay, we assessed accuracy at 1, 2, and 5 months after training. We defined the amount of sustained accuracy needed to achieve competence using cumulative summation analyses and determined the amount of practice needed to reach this level of skill., Results: Twenty-five medical students participated. The median (interquartile range) of cumulative accuracy at the end of the study was 69% (65-78) for dilation and 80% (76-91) for effacement. The sigmoidal model had the best fit. All students achieved competence during the study. The multilevel models showed that accuracy decreased with higher dilation and lower effacement and found that starting level and rate of learning varied between individuals. Maximal accuracy in both dilation and effacement was seen after 150 repetitions. Accuracy of the medical students persisted for 1 month for dilation and 2 months for effacement. The average±SD number of repetitions needed to achieve competence was 89±46 (range 35-195) for dilation and 48±38 (range 11-174) for effacement., Discussion: Based on the variability in skill between individuals and the rate of skill acquisition and decay, we feel that a competence-based rather than time-based approach is most appropriate, that trainee performance should be monitored both during and after training, and that 150 repetitions, or more, should be included in any digital cervical examination simulation regimen.

Background and Objectives: Labor cervical exam accuracy is an essential skill for family medicine and OB-GYN residents to master. To determine the effectiveness of simulation on labor cervical exam training, family medicine and OB-GYN residents were trained using a self-constructed PVC pipe-based cervical exam model during a short and intensive simulation workshop or "boot camp.", Methods: A task trainer was constructed that allows for the blind examination of cervical dilation and effacement. This model was used in the training of first-year family medicine and OB-GYN residents during an 8 day simulation course. A longitudinal comparison of pre- and post-training accuracy was performed. Using a cohort design, the post-training accuracy of first-year family medicine and OB-GYN residents (interns) was also compared to second-fourth year OB-GYN residents., Results: Use of the model by interns (n=25) resulted in significant improvements in the accuracy of their assessments of cervical dilation, but not effacement, and decreased intra-rater variability. When compared to the second-fourth year residents (n=25) who received traditional training, but not simulation training, interns were significantly more accurate and showed less intra-rater variability in their assessments of both dilation and effacement immediately after training compared to their senior colleagues., Conclusions: Training with the cervical exam model improved interns' accuracy and precision immediately after an 8-day simulation course. Use of this model in resident education may aid in the early stages of training and benefit more experienced trainees by augmenting traditional clinical training.

Of graduating obstetrics and gynecology residents, 40% apply for fellowship training and this percentage is likely to increase. The fellowship interview process creates a substantial financial burden on candidates as well as significant challenges in scheduling the multiple interviews for residents, residency programs, and fellowship programs. Coverage with relatively short lead time is needed for some resident rotations, multiple residents may request time off during overlapping time periods, and applicants may not be able to interview based on conflicting interview dates or the inability to find coverage from other residents for their clinical responsibilities. To address these issues, we propose that each subspecialty fellowship within obstetrics and gynecology be allocated a specified and limited time period to schedule their interviews with minimal overlap between subspecialties. Furthermore, programs in close geographic areas should attempt to coordinate their interview dates. This will allow residents to plan their residency rotation schedules far in advance to minimize the impact on rotations that are less amenable to time away from their associated clinical duties, and decrease the numbers of residents needing time off for interviews during any one time period. In addition, a series of formal discussions should take place between subspecialties related to these issues as well as within subspecialties to facilitate coordination., (Copyright © 2016 Elsevier Inc.

Objectives: The purpose of this study was to construct an inexpensive anatomy-based obstetric ultrasound task trainer and investigate whether introduction of this trainer into a hands-on obstetric ultrasound course improved course participants' ultrasound scanning skills., Methods: The trainer was created by placing fetal pigs into preservative-filled heat-sealed polyethylene bags. Twenty-four participants in an obstetric ultrasound course at Wake Forest School of Medicine were randomized to receive hands-on scanning with pregnant women or hands-on scanning and fetal pig simulation. Biometric scans were performed before and after the course. The time to complete the scans, margin of error of biometric measurements, and number of technically adequate images per scan were compared between groups., Results: Twelve participants were randomized into each group. Although a direct comparison of postcourse biometric scans demonstrated no difference between groups, participants that received simulation training showed significant improvements in the time to complete the biometric scan (P < .05) and number of technically adequate images obtained (P < .05), whereas those who did not receive simulation training did not show significant improvements., Conclusions: Addition of the fetal pig ultrasound task trainer resulted in improvements in the course participants' scanning efficiency even after very limited exposure. Incorporating the task trainer earlier and more broadly into obstetric ultrasound training may benefit trainees., (© 2015 by the American Institute of Ultrasound in Medicine.)

Objective: To estimate whether simulation training improves medical students' cervical examination accuracy., Background: The training paradigm for the labor cervical examination exposes patients to additional examinations, lacks a gold standard, and does not objectively assess trainee competence. To address these issues and optimize training, we assessed the effectiveness of cervical examination simulation in third-year medical students., Methods: During the obstetrics and gynecology clerkship, a cohort study was performed in which third-year students were assigned to receive cervical examination simulation (n=50) or vaginal delivery simulation (n=48), with each group serving as a simulation-naive control for the other skill. As a final assessment, students performed 10 cervical examinations using task trainers. Exact accuracy and accuracy within 1 cm were compared between groups. Cumulative summation analyses were performed on the cervical examination group to assess competence and the average number of repetitions needed to achieve it., Results: Cervical examination students were significantly more accurate (Mann-Whitney, P<.001) in assessing dilation (73% exact, 98% within 1 cm) and effacement (83% and 100%) than vaginal delivery students (dilation 52% and 82%, effacement 51% and 96%). In the cumulative summation analyses, 65-100% of students attained competence during the clerkship depending on the level of accuracy and cervical parameter assessed. On average, competence was achieved with 27-44 repetitions., Conclusion: Simulation training dramatically improved student accuracy in labor cervical examinations. Because not all students achieved competence, the cumulative summation analyses suggest that more than 100 repetitions would be needed if the goal was for the entire class of students to achieve competence., Level of Evidence: II.

Obstetric ultrasound is becoming an increasingly important part of the practice of maternal-fetal medicine. Thus, it is important to develop rigorous and effective training curricula for obstetrics and gynecology residents and maternal-fetal medicine fellows. Traditionally, this training has come almost entirely from exposure to ultrasound in the clinical setting. However, with the increased complexity of modern ultrasound and advent of duty-hour restrictions, a purely clinical training model is no longer viable. With the advent of high-fidelity obstetric ultrasound simulators, a significant amount of training can occur in a non-clinical setting which allows learners to obtain significant skill prior to their first patient ultrasound encounter and obtain proficiency in a shorter period of time. In this manuscript we discuss the available obstetric ultrasound simulators and ways to construct a comprehensive ultrasound training curricula to meet the increasing demands of modern maternal-fetal medicine., (Copyright © 2013 Elsevier Inc.

Many fields of medicine now routinely employ simulation while educating all levels of medical trainees. Unfortunately, OB-GYN has been slow to incorporate these beneficial adjuncts to traditional medical education, but thankfully the use of simulation is now increasing. Maternal-Fetal medicine procedures such as amniocentesis, in-utero stent placement, chorionic villus sampling, percutaneous umbilical blood sampling, and cervical cerclage placements are an area where simulation has great potential benefit. Here we describe the currently available simulation models for these procedures and outline specific training curricula designed to aid trainees in obtaining procedural competency in each. Although initial experiences with these training models and the curricula centered around them have been positive, in many cases their use remains limited. Our hope is that this manuscript will encourage others to incorporate simulation into their training programs as we believe it will enhance medical training and improve patient safety., (Copyright © 2013 Elsevier Inc.

Introduction: Performance of cervical cerclage is a difficult procedure for learners with limited operative experience. We present a task trainer for cervical cerclage, which can facilitate learner training in a preclinical environment., Methods: A simulated vagina is first fashioned out of polyvinyl chloride pipe material to allow an appropriately shaped pelvic structure. To simulate collapsible vaginal sidewalls, a foam covered with latex sheets is used to line the inside of the task trainer. A "cervix" is made by cutting cylinders approximately 2 in in diameter and 4 in in length in frozen cow muscle. After thawing, the cervical models are fastened to a semirigid foam disk with suture, which is used to secure the cervix inside the polyvinyl chloride pipe at the top of the simulated vagina. The full cervical cerclage task trainer is then secured in a holder to stabilize it in place. Placement of a cervical cerclage can then be practiced with standard vaginal cerclage instruments., Results: Cervical cerclage can be practiced in a nonclinical environment using this model. Several aspects of the procedure can be modified including the amount of vaginal tissue, length and caliber of the vagina, and pubic arch angle. This model allows beginning learners sequential training of increasing difficulty. Faculty and trainees alike found the trainer to be useful and felt that it helped in the acquisition of the surgical skills needed for cerclage placement in a clinical setting., Conclusions: This low-cost task trainer can provide Maternal-fetal Medicine fellows and obstetric/gynecology residents the opportunity to practice cervical cerclage placement in a nonclinical environment. It may help physicians to obtain or maintain proficiency despite the relative low frequency of the procedure in modern obstetric practice.

Objective: This study developed a lifelike amniocentesis model to allow effective acquisition of the stereotactic skills necessary and comfort level with this procedure., Study Design: An amniocentesis model is constructed using a formalin preserved gravid pig uterus. A large Ziploc freezer bag (Dow, Indianapolis, Ind) filled with ultrasound gel is placed on the uterus to simulate the skin and subcutaneous layer., Results: Amniocentesis can be performed in the usual fashion using this lifelike model. No leak was observed in the Ziploc bag (Dow) or gravid uterus despite more than 50 needle insertions. The cost of 4 to 5 learning stations is approximately $50.00. This model enjoys the advantages of being changeable to reproduce a variety of real-life situations, including poly/oligo/anhydramnios, varied fetal positions and different thickness of subcutaneous tissue., Conclusion: This low-cost novel model provides realistic tissue resistance and yields a sonographically accurate amniocentesis-training tool. The use of this model permits resident instruction in a nonthreatening environment.

Objective: To determine whether hard or soft cervical models produced more accurate results when examined by practitioners of various experience levels., Study Design: Simulated hard and soft cervical models were placed in a chamber designed to simulate a realistic vaginal examination. These cervical dilation and effacement models ranged from 1 cm to 6 cm and from thick (4 cm) to complete (0.2 cm). Each examiner had 20 seconds to evaluate each of 12 models of varying dilation and effacement using the soft and then the hard models. Models of the same dilation and effacement were presented to each practitioner in the same sequence. Physicians, nurses, and residents did the cervical evaluations., Results: Of 360 recorded dilation measurements, only 19% were exactly correct using the soft models, whereas 54% were exact using the hard models. The percentages correct using hard cervix models progressively decreased with advancing cervical dilation. No consistent trend was found using the soft models. The respective results for correct effacement measurements were 49% soft versus 58% hard., Conclusions: Assessment of cervical dilation and effacement was consistently more accurate in the hard, compared with the soft, cervical model. The greatest deviation between the models was noted among the residents, suggesting that beginning practitioners may benefit from learning on firm models before progressing to more realistic soft models. However, it should also be noted that all practitioners might benefit from practice with soft models, especially to determine accurate dilation because scores in this category were consistently below what might be expected.

Rationale and Objectives: To determine if deliberative practice with novel ultrasound guidance targeting tasks improves simulated procedural skill.Materials and Methods: In a nonrandomized interventional trial first year medical students practiced the previous described dowel and straw targeting tasks 1 hour a week for 4 weeks (training group) or had no training (controls). Afterward, they each performed a simulated amniocentesis (AMN) and chorionic villus sampling (CVS) procedure. Procedures were scored using a global rating scale (GRS) and compared between groups with Mann-Whitney U tests. Two-way random effects intraclass correlation coefficients for the inter- and intra-rater variability were calculated for each item in both GRS's.Results: The training group (n = 22) had higher scores on several aspects and overall performance of AMN compared to controls (n = 15). There were no differences between groups for CVS. The inter-rater and intra-rater reliability of the GRS's for both AMN and CVS ranged from 0.16 to 0.89 with most values demonstrating good to excellent agreement.Conclusion: This study demonstrates validity evidence in the content and internal structure domains for the AMN and CVS simulators and their accompanying GRS's. Repetitive practice of the targeting tasks improved student performance in simulated AMN, but modifications are needed for it to be relevant to other procedures such as CVS. [ABSTRACT FROM AUTHOR]

Objective Many fellowship programs in maternal-fetal medicine (MFM) lack sufficient exposure and training in chorionic villus sampling (CVS). We describe a novel training model of transabdominal and transcervical CVS. Methods A porcine heart simulated a 12-week human uterus with a cervical canal created at the apex of the heart. A piglet was placed within a water-filled condom, which was placed inside the "uterus." A second water-filled condom simulated a maternal bladder. Fresh human placenta was placed between the condom and uterine wall. A zipper-sealed freezer bag with ultrasonic gel simulated an abdominal wall. Transabdominal ultrasound was utilized with this model to perform CVS. Results The design involved four MFM specialists and three fellows. Twenty-three faculty MFM specialists and eight MFM fellows endorsed the fidelity of both models. One hundred percent of attendees of a procedural workshop agreed that these models could be used to teach proper technique to fellows and faculty. Conclusion We report a novel training model for transabdominal and transcervical CVS to teach proper technique in a nonclinical setting. [ABSTRACT FROM AUTHOR]

Objective: This study was undertaken to validate a self-administered questionnaire in verifying the diagnosis of preeclampsia, eclampsia, or toxemia in a group of women with a greater than 20-year history of preeclampsia. Study Design: Questionnaires were mailed to a random sample of 144 women who received a diagnosis of any of these 3 conditions and 158 women who had normotensive pregnancies at Mayo Clinic, Rochester, Minnesota, from 1960-1979. Results: A previous diagnosis of preeclampsia, eclampsia, or toxemia was verified with 80% sensitivity and 96% specificity. Conclusion: Our validated questionnaire may be a useful research tool in identifying women with a previous history of preeclampsia. Women with a history of preeclampsia had a higher prevalence of future hypertension than those with a history of normotensive pregnancy. [Copyright &y& Elsevier]

Objective: Because of low health literacy and low priority in seeking prenatal information, health education videos were explored for acceptability by Somali refugee women in a clinical setting. Methods: Focus groups led to the development of six targeted Somali prenatal education videos. Topics include: preparation for pregnancy, nutrition and exercise, pregnancy myths/facts, the father's role, episiotomies, and caesarean sections. Somali participants were recruited to view programs, and completed an 8-item survey prior to regularly scheduled prenatal appointments. Following the clinical visit, providers completed a 4-item survey indicating the video's helpfulness in facilitating client–provider communication. Results: All study participants “strongly recommended” and rated the videos as “appropriate for Somali clients”, 57% indicated the information was “just the right amount,” and 60% found the videos “extremely helpful.” The primary language spoken at home was Somali (72.7%) and 54.5% indicated Somali as the preferred language to receive health information. Providers indicated 24% of appointments were “more interactive” with 72% finding videos “somewhat” or “extremely helpful.” Conclusion: Preliminary results from this pilot study suggest that a video format for prenatal education is acceptable to Somali clients with most clients preferring video health education materials presented in the Somali language. Practice implications: Culturally tailored health education video series for Somali women appear well for use in a clinic setting to facilitate client–provider communication.

Objectives: To evaluate the association of ultrasound measurement of maternal abdominal subcutaneous and pre-peritoneal fat thickness in relation to the subsequent diagnosis of gestational diabetes (GDM), and to assess the association of body fat index (BFI), compared to conventional body mass index (BMI), with respect to the development of some obstetric related complications.Study Design: A prospective study included non-diabetic pregnant women who were scheduled for fetal anatomic survey. Women underwent fat measurements and BFI (pre-peritoneal fat x subcutaneous fat/height) was calculated. They underwent routine glucose screening and diagnostic tests for GDM. Obstetric complications, mode of delivery, and delivery related events were reported. Multivariable logistic regression was used to test potential predictors for development of obesity-related complications. Primary outcome was development of GDM. Secondary outcomes included development of hypertensive disorders during pregnancy and need for cesarean delivery due to labor dystocia. The optimal cut-off points for continuous variables were obtained using a receiver operating characteristic (ROC) curve analyses.Results: 389 women met study criteria. Median gestational age at time of ultrasound evaluation was 19.1 weeks. Positive family history of diabetes (adjusted odds ratio "OR" 2.30, 95% CI 1.35-3.92), history of GDM (adjusted OR 6.87, 95% CI 3.03-15.61), subcutaneous fat≥13 mm (adjusted OR 4.63, 95% CI 1.60-13.38) and pre-peritoneal fat≥12 mm (adjusted OR 3.32, 95% CI 1.06-10.42) were significant predictors for development of GDM. ROC analysis demonstrated that a BFI > 0.5 was statistically superior to a BMI > 25 or 30 as a predictor of gestational diabetes (adjusted OR 6.24, 95% CI 1.86-20.96). A Similar ROC analysis demonstrated that a BFI > 0.8 was associated with a higher risk for the development of hypertensive disorders of pregnancy (adjusted OR 2.70 [95% CI 1.60-4.55]), and need for cesarean delivery (adjusted OR 2.01[95% CI 1.23-3.28]) than a BMI > 25 or 30.Conclusion: Values obtained by ultrasound measurement of subcutaneous and pre-peritoneal fat are associated with development of GDM and hypertensive disorders in pregnancy. Our data suggest that BFI was a better predictor than BMI for development of GDM and hypertensive disorders in pregnancy and should be studied further. [ABSTRACT FROM AUTHOR]

Objective: To determine the amount of simulation training required for students to attain minimal competence and mastery of a vaginal delivery.Methods: An observational study was conducted at a US medical school between May 11, 2015, and May 8, 2016. Using a modified Angoff method, 10 members of the Obstetrics and Gynecology faculty evaluated a vaginal delivery procedural checklist and established cutoff scores for minimal competence and mastery. During a 5-week period, all third-year students received between two and five 45-minute vaginal delivery simulation sessions; performance was assessed during week 6. Performance according to the checklist was compared.Results: The cutoff score was 20 and 26 out of 30 for minimal competence and mastery, respectively. Among 115 students, mean checklist scores in final assessment rose with increasing number of simulations: 23.6, 25.1, 27.5, and 27.6 points for two, three, four, and five training sessions, respectively (P<0.001). The proportion of patients achieving mastery also increased with number of simulations: 34%, 59%, 73%, and 93% for two, three, four, and five training sessions, respectively (P<0.001). Two or three training sessions were sufficient to attain minimal competence in most students; however, no significant between-group difference was found.Conclusion: Simulation training exerts an increasing effect on performance with each additional session that students receive.

Background: Incarceration of the pregnant uterus is a rare condition and can lead to bladder obstruction, renal failure, or uterine rupture. We present a novel, noninvasive technique to reduce an incarcerated uterus.Method: With conscious sedation, the patient was placed in all-fours position. The physician's hands were placed on the patient's abdomen and pressure applied until the uterine fundus was palpated. Gentle, steady fundal pressure on both sides was directed toward the maternal chest (bilateral mediocephalad pressure) elevating the uterus out of the pelvis. This approach successfully reduced the gravid incarcerated uterus and was well tolerated by the patient and fetus.Experience: The author's experience with this method is limited to this case. Prior experience with reduction of the incarcerated uterus has been with methods previously described in the literature.Conclusion: In conjunction with conscious sedation and all-fours positioning, transabdominal manipulation of the uterine fundus with bilateral mediocephalad pressure may facilitate reduction of an incarcerated uterus. This method may obviate the need for more invasive procedures. [ABSTRACT FROM AUTHOR]
