Abstract
PURPOSE Shoulder dystocia is an obstetric emergency with severe complications. Our objective was to evaluate the major pitfalls in the diagnostics of shoulder dystocia, diagnostic descriptions documented in medical records, use of obstetric maneuvers, and their correlations to Erb's and Klumpke's palsy and the use of ICD-10 code 066.0. METHODS A retrospective, register-based case-control study included all deliveries (n = 181 352) in Hospital District of Helsinki and Uusimaa (HUS) area in 2006-2015. Potential shoulder dystocia cases (n = 1708) were identified from the Finnish Medical Birth Register and the Hospital Discharge Register using ICD-10 codes O66.0, P13.4, P14.0, and P14.1. After thorough assessment of all medical records, 537 shoulder dystocia cases were confirmed. Control group consisted of 566 women without any of these ICD-10 codes. RESULTS The pitfalls in the diagnostic included suboptimal following of guidelines for making the diagnosis of shoulder dystocia, subjective interpretation of diagnostic criteria, and inexact or inadequate documentation in medical records. The diagnostic descriptions in medical record were highly inconsistent. The use of obstetric maneuvers was suboptimal among shoulder dystocia cases (57.5%). Overall, the use of obstetric maneuvers increased during the study period (from 25.7 to 97.0%, p < 0.001), which was associated with decreasing rate of Erb's palsy and increasing use of ICD-10 code O66.0. CONCLUSION There are diagnostic pitfalls, which could be addressed by education regarding shoulder dystocia guidelines, by improved use obstetric maneuvers, and more precise documentation. The increased use of obstetric maneuvers was associated with lower rates of Erb's palsy and improved coding of shoulder dystocia.

[PMID: 37652778 DOI: 10.1016/j.ajog.2023.01.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 01/16/2023] [Accepted: 01/17/2023] [Indexed: 09/02/2023]
Abstract
In the management of shoulder dystocia, it is often recommended to start with external maneuvers, such as the McRoberts maneuver and suprapubic pressure, followed by internal maneuvers including rotation and posterior arm delivery. However, this sequence is not based on scientific evidence of its success rates, the technical simplicity, or the related complication rates. Hence, this review critically evaluates the success rate, technique, and safety of different maneuvers. Retrospective reviews showed that posterior arm delivery has consistently higher success rates (86.1%) than rotational methods (62.4%) and external maneuvers (56.0%). McRoberts maneuver was thought to be a simple method, however, its mechanism is not clear. Furthermore, McRoberts position still requires subsequent traction on the fetal neck, which presents a risk for brachial plexus injury. The 2 internal maneuvers have anatomic rationales with the aim of rotating the shoulders to the wider oblique pelvic dimension or reducing the shoulder width. The techniques are not more sophisticated and requires the accoucher to insert the correct hand (according to fetal face direction) through the more spacious sacro-posterior region and deep enough to reach the fetal chest or posterior forearm. The performance of rotation and posterior arm delivery can also be integrated and performed using the same hand. Retrospective studies may give a biased view that the internal maneuvers are riskier. First, a less severely impacted shoulder dystocia is more likely to have been managed by external maneuvers, subjecting more difficult cases to internal maneuvers. Second, neonatal injuries were not necessarily caused by the internal maneuvers that led to delivery but could have been caused by the preceding unsuccessful external maneuvers. The procedural safety is not primarily related to the nature of the maneuvers, but to how properly these maneuvers are performed. When all these maneuvers have failed, it is important to consider the reasons for failure otherwise repetition of the maneuver cycle is just a random trial and error. If the posterior axilla is just above the pelvic outlet and reachable, posterior axilla traction using either the accoucher fingers or a sling is a feasible alternative. Its mechanism is not just outward traction but also rotation of the shoulders to the wider oblique pelvic dimension. If the posterior axilla is at a higher sacral level, a sling may be formed with the assistance of a long right-angle forceps, otherwise, more invasive methods such as Zavanelli maneuver, abdominal rescue, or symphysiotomy are the last resorts.

Acta Obstet Gynecol Scand 2024. [PMID: 38276972 DOI: 10.1111/aogs.14780] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 12/12/2023] [Accepted: 01/02/2024] [Indexed: 01/27/2024]
Abstract
INTRODUCTION Shoulder dystocia is a severe obstetric emergency that can cause substantial neonatal and maternal complications. This study aims to assess the performed obstetric maneuvers and their frequency, success, and association with maternal and neonatal complication rates. MATERIAL AND METHODS The study population was collected among all deliveries in the Hospital District of Helsinki and Uusimaa between 2006 and 2015 (n = 181 352) by searching for ICD-10 codes for shoulder dystocia, brachial plexus injury and clavicle fracture. Shoulder dystocia cases (n = 537) were identified by reviewing the medical records. Shoulder dystocia cases treated with one or two maneuvers were compared with those treated with at least three. Medical records of a matched control group constituting of 566 parturients without any of the forementioned ICD-10 codes were also scrutinized. RESULTS Using the four most common obstetric maneuvers (McRoberts maneuver, suprapubic pressure, rotational maneuvers, the delivery of the posterior arm) significantly increased during the study period with individual success rates of 61.0%, 71.9%, 68.1% and 84.8%, respectively. Concurrently, the rate of brachial plexus injury and combined neonatal morbidity significantly declined from 50% to 24.2% (p = 0.02) and from 91.4% to 48.5% (p < 0.001). Approximately 75% of shoulder dystocia cases treated with maneuvers were resolved by the McRoberts maneuver and/or suprapubic pressure, but each of the four most performed maneuvers significantly increased the cumulative success rate individually and statistically (p < 0.001). The rates of brachial plexus injury and combined neonatal morbidity were at their highest (52.9% and 97.8%) when none of the maneuvers were performed and at their lowest when two maneuvers were performed (43.0% and 65.4%). The increasing number (≥3) of maneuvers did not affect the combined maternal or neonatal morbidity or brachial plexus injury but increased the risk for third- or fourth-degree lacerations (odds ratio 2.91, 95% confidence interval 1.17 to 7.24). CONCLUSIONS The increased use of obstetric maneuvers during the study period was associated with decreasing rates of neonatal complications; conversely, the lack of obstetric maneuvers was associated with the highest rate of neonatal complications. These emphasize the importance of education, maneuver training and urgently performing shoulder dystocia maneuvers according to the international protocol guidelines.

J Biomech Eng 2024; 146:021009. [PMID: 38116838 PMCID: PMC10880949 DOI: 10.1115/1.4064313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 11/02/2023] [Accepted: 11/05/2023] [Indexed: 12/21/2023]
Abstract
The purpose of this computational study was to investigate the effects of neonate-focused clinical delivery maneuvers on brachial plexus (BP) during shoulder dystocia. During shoulder dystocia, the anterior shoulder of the neonate is obstructed behind the symphysis pubis of the maternal pelvis, postdelivery of the neonate's head. This is managed by a series of clinical delivery maneuvers. The goal of this study was to simulate these delivery maneuvers and study their effects on neonatal BP strain. Using madymo models of a maternal pelvis and a 90th-percentile neonate, various delivery maneuvers and positions were simulated including the lithotomy position alone of the maternal pelvis, delivery with the application of various suprapubic pressures (SPPs), neonate in an oblique position, and during posterior arm delivery maneuver. The resulting BP strain (%) along with the required maternal delivery force was reported in these independently simulated scenarios. The lithotomy position alone served as the baseline. Each of the successive maneuvers reported a decrease in the required delivery force and resulting neonatal BP strain. As the applied SPP force increased (three scenarios simulated), the required maternal delivery force and neonatal BP strain decreased. A further decrease in both delivery force and neonatal BP strain was observed in the oblique position, with the lowest delivery force and neonatal BP strain reported during the posterior arm delivery maneuver. Data obtained from the improved computational models in this study enhance our understanding of the effects of clinical maneuvers on neonatal BP strain during complicated birthing scenarios such as shoulder dystocia.

Abstract
PURPOSE There are few data on maternal and neonatal morbidities associated with shoulder dystocia (SD), depending on the use of fetal manipulation (FM). A prior 5-year study was conducted in our center in 2012 for this purpose. Our objective was to compare severe maternal and neonatal morbidities according to FM execution in a larger cohort. METHODS We conducted a retrospective study between 2007 and 2020. SD was considered when additional maneuvers were required to complete a delivery. Severe maternal morbidity was defined as the occurrence of obstetric anal sphincter injury (OASI). Severe neonatal morbidity was defined as Apgar < 7 at 5 min and/or cord arterial pH < 7.1 and/or or a permanent brachial plexus palsy. We studied these data in the FM group compared to the non- FM group. RESULTS FM was associated with increased OASI rates (21.1% vs. 3.8%, OR = 6.72 [2.7-15.8]). We found no significant difference in severe neonatal morbidity. Maternal age > 35 and FM appear to be associated with the occurrence of OASI, with ORa = 13.3 [1.5-121.8] and ORa = 5.3 [2.2-12.8], respectively. FM was the only factor associated with the occurrence of severe neonatal morbidity (ORa = 2.3 [1.1-4.8]. The rate of episiotomy was significantly decreased (20% versus 5% p < 0.05) and there was an increase in the rate of SD managed with FM in our center. CONCLUSION FM is the only factor associated with an increased risk of OASI. In case of failure of non-FM maneuvers, the rapid implementation of FM maneuvers resulted in no difference regarding severe neonatal morbidity.

Abstract
OBJECTIVE To study the impact of shoulder dystocia (SD) simulation training on the management of SD and the incidence of permanent brachial plexus birth injury (BPBI). DESIGN Retrospective observational study. SETTING Helsinki University Women's Hospital, Finland. SAMPLE Deliveries with SD. METHODS Multi-professional, regular and systematic simulation training for obstetric emergencies began in 2015, and SD was one of the main themes. A study was conducted to assess changes in SD management and the incidence of permanent BPBI. The study period was from 2010 to 2019; years 2010-2014 were considered the pre-training period and years 2015-2019 were considered the post-training period. MAIN OUTCOME MEASURES The primary outcome measure was the incidence of permanent BPBI after the implementation of systematic simulation training. Changes in the management of SD were also analysed. RESULTS During the study period, 113 085 vertex deliveries were recorded. The incidence of major SD risk factors (gestational diabetes, induction of labour, vacuum extraction) increased and was significantly higher for each of these factors during the post-training period (p < 0.001). The incidence of SD also increased significantly (0.01% vs 0.3%, p < 0.001) during the study period, but the number of children with permanent BPBI decreased by 55% after the implementation of systematic simulation training (0.05% vs 0.02%, p < 0.001). The most significant change in the management of SD was the increased incidence of successful delivery of the posterior arm. CONCLUSIONS Systematic simulation-based training of midwives and doctors can translate into improved individual and team performance and can significantly reduce the incidence of permanent BPBI.

Abstract
The pathophysiologic origins of obstetrical emergencies are complicated and may well be influenced by events prior to conception. Such problems are not likely to be resolved soon, and in the meantime, high-resource countries simply cannot afford to divert more and more money to litigation and the costs of preventable morbidities for either mother or child. It is long past time we tackled these acute care problems where most first occur-the Maternity unit. It is reasonable to ask whether hospitals (and society at large) are getting what they believe they are buying. Training to satisfy a regulation without improving patient outcomes functionally erects one more barrier to the pursuit of optimal patient outcomes. Why then continue squandering limited resources and precious lives if current hospital training is not improving outcomes? In this monograph, I focus on training programs for the management of obstetrical emergencies.

Abstract
OBJECTIVE This study aimed to evaluate the outcomes associated with the implementation of simulation exercises to reduce the sequela of shoulder dystocia. DATA SOURCES Electronic databases (Ovid MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature database, and Scopus) were initially queried in June 2020 and updated in November 2020. The following 3 concepts were introduced and refined using the controlled vocabulary of the database: vaginal birth, shoulder dystocia, and simulation training. There were no limitations to the year of publication as part of the search strategy. STUDY ELIGIBILITY CRITERIA We included all studies that reported on the frequency of shoulder dystocia and the associated complications before and after the implementation of interventional exercises to improve outcomes. METHODS Two authors independently assessed the abstracts and full-text articles of all studies for eligibility and evaluated the quality of the included studies using the Newcastle-Ottawa Scale. Any inconsistencies related to study evaluation or data extraction were resolved by a third author. The coprimary outcomes of this systematic review and meta-analysis were neonatal brachial plexus palsy diagnosed following deliveries complicated by shoulder dystocia and persistence of brachial palsy at 12 months or later. The secondary outcomes were the frequency of shoulder dystocia and cesarean delivery. Study effects were combined using a Bayesian meta-analysis and were reported as risk ratios and 95% credible intervals (Crs). RESULTS Of the 372 articles reviewed, 16 publications, which included 428,552 deliveries with 217,713 (50.8%) deliveries during the preintervention and 210,839 (49.2%) deliveries during the postinterventional period, were included in the meta-analysis. The incidence of neonatal brachial plexus palsy after shoulder dystocia decreased from 12.1% to 5.7% (risk ratio, 0.37; 95% Cr, 0.26-0.57; probability of reduction 100%). The overall proportion of neonatal brachial plexus palsy decreased, but with less precision, from 0.3% to 0.1% (risk ratio, 0.53; 95% Cr, 0.21-1.26; probability of reduction 94%). Two studies followed newborns with brachial plexus palsy for at least 12 months. One study that reported on persistent neonatal brachial plexus palsy at 12 months among 1148 shoulder dystocia cases noted a reduction in persistent neonatal brachial plexus palsy from 1.9% to 0.2% of shoulder dystocia cases (risk ratio, 0.13; 95% confidence interval, 0.04-0.49). In contrast, the study that reported on persistent neonatal brachial plexus palsy at 12 months for all deliveries noted that it did not change significantly, namely from 0.3 to 0.2 per 1000 births (risk ratio, 0.77; 95% confidence interval, 0.31-1.90). Following the implementation of shoulder dystocia interventional exercises, the diagnosis of shoulder dystocia increased significantly from 1.2% to 1.7% of vaginal deliveries (risk ratio, 1.39; 95% Cr, 1.19-1.65; probability of increase 100%). Compared with the preimplementation period, the cesarean delivery rate increased postimplementation from 21.2% to 25.9% (risk ratio, 1.22; 95% Cr, 0.93-1.59; probability of increase 93%). We created an online tool (https://ccrebm-bell.shinyapps.io/sdmeta/) that permits calculation of the absolute risk reduction and absolute risk increase attributable to the intervention vis-à-vis the incidence of shoulder dystocia, neonatal brachial plexus palsy, and cesarean deliveries. CONCLUSION Introduction of shoulder dystocia interventional exercises decreased the rate of neonatal brachial plexus palsy per shoulder dystocia case; the data on persistence of neonatal brachial plexus palsy beyond 12 months is limited and contradictory. Implementation of the interventions was associated with an increase in the diagnosis of shoulder dystocia and rate of cesarean deliveries.

Abstract
The interpretation of umbilical cord gases may not be straightforward following shoulder dystocia. We reviewed Perinatal and Maternal Mortality Review Committee data from New Zealand infants with moderate and severe neonatal encephalopathy (NE) for 2010-2017 inclusive. If one or more of: pH of ≤7.1; base excess of ≤-12 mmol/L; or lactate of ≥6 mmol/L were present it was considered an abnormal result. One-third (12/36) of infants born following shoulder dystocia had documented umbilical cord gases within the normal range. It is important for clinicians to be aware of this possibility when assessing newborn infants with NE.

Late Pregnancy Ultrasound to Screen for and Manage Potential Birth Complications in Nulliparous Women: A Cost-Effectiveness and Value of Information Analysis. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2021; 24:513-521.

Abstract
BACKGROUND Fetal growth restriction is a major risk factor for stillbirth. A routine late-pregnancy ultrasound scan could help detect this, allowing intervention to reduce the risk of stillbirth. Such a scan could also detect fetal presentation and predict macrosomia. A trial powered to detect stillbirth differences would be extremely large and expensive. OBJECTIVES It is therefore critical to know whether this would be a good investment of public research funds. The aim of this study is to estimate the cost-effectiveness of various late-pregnancy screening and management strategies based on current information and predict the return on investment from further research. METHODS Synthesis of current evidence structured into a decision model reporting expected costs, quality-adjusted life-years, and net benefit over 20 years and value-of-information analysis reporting predicted return on investment from future clinical trials. RESULTS Given a willingness to pay of £20 000 per quality-adjusted life-year gained, the most cost-effective strategy is a routine presentation-only scan for all women. Universal ultrasound screening for fetal size is unlikely to be cost-effective. Research exploring the cost implications of induction of labor has the greatest predicted return on investment. A randomized, controlled trial with an endpoint of stillbirth is extremely unlikely to be a value for money investment. CONCLUSION Given current value-for-money thresholds in the United Kingdom, the most cost-effective strategy is to offer all pregnant women a presentation-only scan in late pregnancy. A randomized, controlled trial of screening and intervention to reduce the risk of stillbirth following universal ultrasound to detect macrosomia or fetal growth restriction is unlikely to represent a value for money investment.

[PMID: 33757935 PMCID: PMC10176198 DOI: 10.1016/j.ajogmf.2021.100359] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 02/28/2021] [Accepted: 03/16/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Although the neonatal morbidity associated with shoulder dystocia are well known, the maternal morbidity caused by this obstetrical emergency is infrequently reported. OBJECTIVE This study aimed to assess the composite adverse maternal and neonatal outcomes among vaginal deliveries (at 34 weeks or later) with and without shoulder dystocia. STUDY DESIGN This is a secondary analysis of the Consortium of Safe Labor, an observational obstetrical cohort of all vaginal deliveries occurring at 19 hospitals (from 2002-2008) and for which data on the occurrence of shoulder dystocia were available. The composite adverse maternal outcome included third- or fourth-degree perineal laceration, postpartum hemorrhage (>500 cc blood loss for a vaginal delivery and >1000 cc blood loss for cesarean delivery), blood transfusion, chorioamnionitis, endometritis, thromboembolism, admission to intensive care unit, or maternal death. The composite adverse neonatal outcome included an Apgar score of <7 at 5 minutes, a birth injury, neonatal seizure, hypoxic ischemic encephalopathy, or neonatal death. A multivariable Poisson regression was used to estimate the adjusted relative risks with 95% confidence intervals. The area under the receiver operating characteristic curve was constructed to determine if clinical factors would identify shoulder dystocia. RESULTS Of the 228,438 women in the overall cohort, 130,008 (59.6%) met the inclusion criteria, and among them, shoulder dystocia was documented in 2159 (1.7%) cases. The rate of composite maternal morbidity was significantly higher among deliveries with shoulder dystocia (14.7%) than without (8.6%; adjusted relative risk, 1.71; 95% confidence interval, 1.64-2.01). The most common maternal morbidity with shoulder dystocia was a third- or fourth-degree laceration (adjusted relative risk, 2.82; 95% confidence interval, 2.39-3.31). The risk of composite neonatal morbidity with shoulder dystocia (12.2%) was also significantly higher than without shoulder dystocia (2.4%) (adjusted relative risk, 5.18; 95% confidence interval, 4.60-5.84). The most common neonatal morbidity was birth injury (adjusted relative risk, 5.39; 95% confidence interval, 4.71-6.17). The area under the curve for maternal characteristics to identify shoulder dystocia was 0.66 and it was 0.67 for intrapartum factors. CONCLUSION Although shoulder dystocia is unpredictable, the associated morbidity affects both mothers and newborns. The focus should be on concurrently averting the composite morbidity for the maternal-neonatal dyad with shoulder dystocia.

Abstract
OBJECTIVE To determine the cost-utility of a multi-professional simulation training programme for obstetric emergencies-Practical Obstetric Multi-Professional Training (PROMPT)-with a particular focus on its impact on permanent obstetric brachial plexus injuries (OBPIs). DESIGN A model-based cost-utility analysis. SETTING Maternity units in England. POPULATION Simulated cohorts of individuals affected by permanent OBPIs. METHODS A decision tree model was developed to estimate the cost-utility of adopting annual, PROMPT training (scenario 1a) or standalone shoulder dystocia training (scenario 1b) in all maternity units in England compared to current practice, where only a proportion of English units use the training programme (scenario 2). The time horizon was 30 years and the analysis was conducted from an English National Health Service (NHS) and Personal Social Services perspective. A probabilistic sensitivity analysis was performed to account for uncertainties in the model parameters. MAIN OUTCOME MEASURES Outcomes for the entire simulated period included the following: total costs for PROMPT or shoulder dystocia training (including costs of OBPIs), number of OBPIs averted, number of affected adult/parental/dyadic quality adjusted life years (QALYs) gained and the incremental cost per QALY gained. RESULTS Nationwide PROMPT or shoulder dystocia training conferred significant savings (in excess of £1 billion ($1.5 billion)) compared to current practice, resulting in cost-savings of at least £1 million ($1.5 million) per any type of QALY gained. The probabilistic sensitivity analysis demonstrated similar findings. CONCLUSION In this model, national implementation of multi-professional simulation training for obstetric emergencies (or standalone shoulder dystocia training) in England appeared to both be cost-saving when evaluating their impact on permanent OBPIs.

Abstract
Background: Several factors associated with B glenoid are also linked with obstetrical brachial plexus palsy (OBPP). The purpose of this observational study was to determine the incidence of OBPP risk factors in type B patients. Methods: A cohort of 154 patients (68% men, 187 shoulders) aged 63 ± 17 years with type B glenoids completed a questionnaire comprising history of perinatal characteristics related to OBPP. A literature review was performed following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) to estimate the incidence of OBPP risk factors in the general population. Results: Twenty-seven patients (18%) reported one or more perinatal OBPP risk factors, including shoulder dystocia (n = 4, 2.6%), macrosomia >4 kg (n = 5, 3.2%), breech delivery (n = 6, 3.9%), fetal distress (n = 8, 5.2%), maternal diabetes (n = 2, 1.3%), clavicular fracture (n = 2, 1.3%), and forceps delivery (n = 4, 2.6%). The comparison with the recent literature suggested that most perinatal OBPP risk factors were within the normal range, although the incidence of shoulder dystocia, forceps and vaginal breech deliveries exceeded the average rates. Conclusion: Perinatal factors related to OBPP did not occur in a higher frequency in patients with Walch type B OA compared to the general population, although some of them were in the high normal range.

Abstract
BACKGROUND Currently, pregnant women are screened using ultrasound to perform gestational aging, typically at around 12 weeks' gestation, and around the middle of pregnancy. Ultrasound scans thereafter are performed for clinical indications only. OBJECTIVES We sought to assess the case for offering universal late pregnancy ultrasound to all nulliparous women in the UK. The main questions addressed were the diagnostic effectiveness of universal late pregnancy ultrasound to predict adverse outcomes and the cost-effectiveness of either implementing universal ultrasound or conducting further research in this area. DESIGN We performed diagnostic test accuracy reviews of five ultrasonic measurements in late pregnancy. We conducted cost-effectiveness and value-of-information analyses of screening for fetal presentation, screening for small for gestational age fetuses and screening for large for gestational age fetuses. Finally, we conducted a survey and a focus group to determine the willingness of women to participate in a future randomised controlled trial. DATA SOURCES We searched MEDLINE, EMBASE and the Cochrane Library from inception to June 2019. REVIEW METHODS The protocol for the review was designed a priori and registered. Eligible studies were identified using keywords, with no restrictions for language or location. The risk of bias in studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. Health economic modelling employed a decision tree analysed via Monte Carlo simulation. Health outcomes were from the fetal perspective and presented as quality-adjusted life-years. Costs were from the perspective of the public sector, defined as NHS England, and the costs of special educational needs. All costs and quality-adjusted life-years were discounted by 3.5% per annum and the reference case time horizon was 20 years. RESULTS Umbilical artery Doppler flow velocimetry, cerebroplacental ratio, severe oligohydramnios and borderline oligohydramnios were all either non-predictive or weakly predictive of the risk of neonatal morbidity (summary positive likelihood ratios between 1 and 2) and were all weakly predictive of the risk of delivering a small for gestational age infant (summary positive likelihood ratios between 2 and 4). Suspicion of fetal macrosomia is strongly predictive of the risk of delivering a large infant, but it is only weakly, albeit statistically significantly, predictive of the risk of shoulder dystocia. Very few studies blinded the result of the ultrasound scan and most studies were rated as being at a high risk of bias as a result of treatment paradox, ascertainment bias or iatrogenic harm. Health economic analysis indicated that universal ultrasound for fetal presentation only may be both clinically and economically justified on the basis of existing evidence. Universal ultrasound including fetal biometry was of borderline cost-effectiveness and was sensitive to assumptions. Value-of-information analysis indicated that the parameter that had the largest impact on decision uncertainty was the net difference in cost between an induced delivery and expectant management. LIMITATIONS The primary literature on the diagnostic effectiveness of ultrasound in late pregnancy is weak. Value-of-information analysis may have underestimated the uncertainty in the literature as it was focused on the internal validity of parameters, which is quantified, whereas the greatest uncertainty may be in the external validity to the research question, which is unquantified. CONCLUSIONS Universal screening for presentation at term may be justified on the basis of current knowledge. The current literature does not support universal ultrasonic screening for fetal growth disorders. FUTURE WORK We describe proof-of-principle randomised controlled trials that could better inform the case for screening using ultrasound in late pregnancy.

Abstract
Improving maternal and perinatal care is a global priority. Simulation training and novel applications of simulation for intrapartum care may help to reduce preventable deaths worldwide. Evaluation studies have published details of the effectiveness of simulation training for obstetric emergencies, exploring clinical and non-clinical factors as well as the impact on patient outcomes (both maternal and neonatal). This review summarized the many uses of simulation in obstetric emergencies from training to assessment. It also described the adaption of training in low-resource settings and the evidence behind the equipment recommended to support simulation training. The review also discussed novel applications for simulation such as its use in the development of a new device for assisted vaginal birth and its potential role in Cesarean section training. This study analyzed the financial implications of simulation training and how this may impact the delivery of such training packages, considering that simulation should be developed and utilized as a key tool in the development of safe intrapartum care in both emergency and non-emergency settings, in innovation and product development.

Rising trends in the incidence of shoulder dystocia and development of a novel shoulder dystocia risk score tool: a nationwide population-based study of 800 484 Finnish deliveries. Acta Obstet Gynecol Scand 2020; 100:538-547.

Abstract
INTRODUCTION Shoulder dystocia has remained an unpredictable and feared emergency in obstetrics. Some risk factors have been identified but nevertheless there is a lack of risk evaluation tools in clinical practice. The aim of this study was to evaluate the incidence and risk factors of shoulder dystocia in the Finnish population and to develop a shoulder dystocia risk score tool. MATERIAL AND METHODS This retrospective, population-based study included all deliveries in Finland between 2004 and 2017 (n = 800 484). The annual numbers of shoulder dystocia diagnoses were gathered from nationwide Finnish Medical Birth Register and Hospital Discharge Register. The incidence of shoulder dystocia was calculated in subgroups according to the mode of delivery, maternal diabetes status, body mass index (BMI), age, parity and gestational age. Based on these numbers, a shoulder dystocia risk score tool was created. RESULTS The overall incidence of shoulder dystocia was 0.18%. It increased significantly during the study period from 0.10% to 0.32% (P < .001). More specifically, the incidence increased significantly in all analyzed subgroups except for women with BMI <18.5 or age <20 years. To evaluate the importance of risk factors, practical and simple shoulder dystocia risk score tool was created. Instrumental vaginal delivery, maternal diabetes of any kind, BMI ≥25, age ≥40 years and gestational age ≥41 weeks were associated with higher shoulder dystocia risk compared with non-diabetic, non-obese and younger women with spontaneous deliveries before 41 weeks of gestation. In our risk score tool, cases with shoulder dystocia had a significantly higher number of risk points than those without it (15.2 vs 10.4, P < .001). The risk was significantly high when the scores were ≥18 points (relative risk 9.54, 95% confidence interval 8.61-10.57). CONCLUSIONS The incidence of shoulder dystocia in Finland increased during the study period but it is still low compared with previous studies from other countries. In clinical daily practice, the new shoulder dystocia risk score tool helps to evaluate the individual risk profile of the parturient. According to this risk score tool, the highest risk was found with the combination of instrumental vaginal delivery, maternal diabetes, BMI ≥25, age ≥40 years and gestational age ≥41 weeks.

Abstract
The shoulder shrug maneuver is a simple technique to learn that can aid the obstetrician in the management of shoulder dystocia. BACKGROUND: Shoulder dystocia is a potential complication of vaginal delivery that increases the chances of injury to the neonate and the mother. The incidence of dystocia can be up to 3%, and sudden presentation and the lack of reliable predictors make shoulder dystocia a challenge for obstetricians. TECHNIQUE: The shoulder shrug technique involves shrugging the posterior shoulder and rotating the head–shoulder unit 180 degrees to resolve the shoulder dystocia. EXPERIENCE: We describe successful delivery in three cases of persistent shoulder dystocia using the shoulder shrug technique after the dystocia could not be resolved with McRoberts maneuver. CONCLUSION: When successful, the shoulder shrug maneuver may decrease the likelihood of morbidity for the neonate. The technique has resolved dystocia in three cases in which the posterior shoulder could be shrugged. Because it does not take much time to perform the shoulder shrug maneuver, it is worth considering this technique during management of unresolved shoulder dystocia.

Abstract
Providing quality emergency obstetric care (EmOC) reduces the risk of maternal and newborn mortality and morbidity. There is evidence that over 50% of maternal health programmes that result in improving access to EmOC and reduce maternal mortality have an EmOC training component. The objective was to review the evidence for the effectiveness of training in EmOC. Eleven databases and websites were searched for publications describing EmOC training evaluations between 1997 and 2017. Effectiveness was assessed at four levels: (1) participant reaction, (2) knowledge and skills, (3) change in behaviour and clinical practice and (4) availability of EmOC and health outcomes. Weighted means for change in knowledge and skills obtained, narrative synthesis of results for other levels. One hundred and one studies including before-after studies (n = 44) and randomized controlled trials (RCTs) (n = 15). Level 1 and/or 2 was assessed in 68 studies; Level 3 in 51, Level 4 in 21 studies. Only three studies assessed effectiveness at all four levels. Weighted mean scores pre-training, and change after training were 67.0% and 10.6% for knowledge (7750 participants) and 53.1% and 29.8% for skills (6054 participants; 13 studies). There is strong evidence for improved clinical practice (adherence to protocols, resuscitation technique, communication and team work) and improved neonatal outcomes (reduced trauma after shoulder dystocia, reduced number of babies with hypothermia and hypoxia). Evidence for a reduction in the number of cases of post-partum haemorrhage, case fatality rates, stillbirths and institutional maternal mortality is less strong. Short competency-based training in EmOC results in significant improvements in healthcare provider knowledge/skills and change in clinical practice. There is emerging evidence that this results in improved health outcomes.

Abstract
BACKGROUND At Counties Manukau Health in Auckland, New Zealand, axillary traction is being used when an internal manoeuvre is required for resolution of shoulder dystocia. AIMS This study presents the outcomes for mother and baby from use of axillary traction and other internal manoeuvres. MATERIALS AND METHODS Retrospective review of the clinical records of mother and baby for all labours complicated by shoulder dystocia was carried out for an eight-year period. Maternal and neonatal information were compared for the three cohorts of the first internal manoeuvre documented: axillary traction, posterior arm delivery and rotational manoeuvres. RESULTS There were 226 women who required the use of internal manoeuvres with no significant differences in age, body mass index, parity, ethnicity, diabetes incidence, induction and augmentation of labour rates, length of the first stage and birth weight between the cohorts. Axillary traction was the first internal manoeuvre used for 119 (52.7%) with a success rate of 95.8%. Posterior arm delivery was used first for 49 (21.7%) women with a success rate of 85.7%. Rotational manoeuvres were used first for 58 (25.7%) women with a statistically inferior success rate of 48.3%. There was no significant difference in the maternal and neonatal complication rates between the cohorts. CONCLUSION Axillary traction has been utilised as the first internal manoeuvre for a large number of women with a higher success rate than other internal manoeuvres without any increase in maternal or neonatal morbidity. It is recommended that this be the first internal manoeuvre attempted when shoulder dystocia occurs.

Abstract
BACKGROUND Preparing healthcare providers to manage relatively rare life-threatening emergency situations effectively is a challenge. Training sessions enable staff to rehearse for these events and are recommended by several reports and guidelines. In this review we have focused on interactive training, this includes any element where the training is not solely didactic but provides opportunity for discussions, rehearsals, or interaction with faculty or technology. It is important to understand the effective methods and essential elements for successful emergency training so that resources can be appropriately targeted to improve outcomes. OBJECTIVES To assess the effects of interactive training of healthcare providers on the management of life-threatening emergencies in hospital on patient outcomes, clinical care practices, or organisational practices, and to identify essential components of effective interactive emergency training programmes. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL and ERIC and two trials registers up to 11 March 2019. We searched references of included studies, conference proceedings, and contacted study authors. SELECTION CRITERIA We included randomised trials and cluster-randomised trials comparing interactive training for emergency situations with standard/no training. We defined emergency situations as those in which immediate lifesaving action is required, for example cardiac arrests and major haemorrhage. We included all studies where healthcare workers involved in providing direct clinical care were participants. We excluded studies outside of a hospital setting or where the intervention was not targeted at practicing healthcare workers. We included trials irrespective of publication status, date, and language. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane and Cochrane Effective Practice and Organisation of Care (EPOC) Group. Two review authors independently extracted data and assessed the risk of bias of each included trial. Due to the small number of studies and the heterogeneity in outcome measures, we were unable to perform the planned meta-analysis. We provide a structured synthesis for the following outcomes: survival to hospital discharge, morbidity rate, protocol or guideline adherence, patient outcomes, clinical practice outcomes, and organisation-of-care outcomes. We used the GRADE approach to rate the certainty of the evidence and the strength of recommendations for each outcome. MAIN RESULTS We included 11 studies that reported on 2000 healthcare providers and over 300,000 patients; one study did not report the number of participants. Seven were cluster randomised trials and four were single centre studies. Four studies focused on obstetric training, three on obstetric and neonatal care, two on neonatal training, one on trauma and one on general resuscitations. The studies were spread across high-, middle- and low-income settings.Interactive training may make little or no difference in survival to hospital discharge for patients requiring resuscitation (1 study; 30 participants; 98 events; low-certainty evidence). We are uncertain if emergency training changes morbidity rate, as the certainty of the evidence is very low (3 studies; 1778 participants; 57,193 patients, when reported). We are uncertain if training alters healthcare providers' adherence to clinical protocols or guidelines, as the certainty of the evidence is very low (3 studies; 156 participants; 558 patients). We are uncertain if there were improvements in patient outcomes following interactive training for emergency situations, as we assessed the evidence as very low-certainty (5 studies, 951 participants; 314,055 patients). We are uncertain if training for emergency situations improves clinical practice outcomes as the certainty of the evidence is very low (4 studies; 1417 participants; 28,676 patients, when reported). Two studies reported organisation-of-care outcomes, we are uncertain if interactive emergency training has any effect on this outcome as the certainty of the evidence is very low (634 participants; 179,400 patient population).We examined prespecified subgroups and found no clear commonalities in effect of multidisciplinary training, location of training, duration of the course, or duration of follow-up. We also examined areas arising from the studies including focus of training, proportion of staff trained, leadership of intervention, and incentive/trigger to participate, and again identified no clear mediating factors. The sources of funding for the studies were governmental, local organisations, or philanthropic donors. AUTHORS' CONCLUSIONS We are uncertain if there are any benefits of interactive training of healthcare providers on the management of life-threatening emergencies in hospital as the certainty of the evidence is very low. We were unable to identify any factors that may have allowed us to identify an essential element of these interactive training courses.We found a lack of consistent reporting, which contributed to the inability to meta-analyse across specialities. More trials are required to build the evidence base for the optimum way to prepare healthcare providers for rare life-threatening emergency events. These trials need to be conducted with attention to outcomes important to patients, healthcare providers, and policymakers. It is vitally important to develop high-quality studies adequately powered and with attention to minimising the risk of bias.

Effect of hands-on interprofessional simulation training for local emergencies in Scotland: the THISTLE stepped-wedge design randomised controlled trial. BMJ Qual Saf 2019; 29:122-134.

Abstract
OBJECTIVE To assess whether the implementation of an intrapartum training package (PROMPT (PRactical Obstetric Multi-Professional Training)) across a health service reduced the proportion of term babies born with Apgar score <7 at 5 min (<75mins). DESIGN Stepped-wedge cluster randomised controlled trial. SETTING Twelve randomised maternity units with ≥900 births/year in Scotland. Three additional units were included in a supplementary analysis to assess the effect across Scotland. The intervention commenced in March 2014 with follow-up until September 2016. INTERVENTION The PROMPT training package (Second edition), with subsequent unit-level implementation of PROMPT courses for all maternity staff. MAIN OUTCOME MEASURES The primary outcome was the proportion of term babies with Apgar<75mins. RESULTS 87 204 eligible births (99.2% with an Apgar score), of which 1291 infants had an Apgar<75mins were delivered in the 12 randomised maternity units. Two units did not implement the intervention. The overall Apgar<75mins rate observed in the 12 randomised units was 1.49%, increasing from 1.32% preintervention to 1.59% postintervention. Once adjusted for a secular time trend, the 'intention-to-treat' analysis indicated a moderate but non-significant reduction in the rate of term babies with an Apgar scores <75mins following PROMPT training (OR=0.79 95%CI(0.63 to 1.01)). However, some units implemented the intervention earlier than their allocated step, whereas others delayed the intervention. The content and authenticity of the implemented intervention varied widely at unit level. When the actual date of implementation of the intervention in each unit was considered in the analysis, there was no evidence of improvement (OR=1.01 (0.84 to 1.22)). No intervention effect was detected by broadening the analysis to include all 15 large Scottish maternity units. Units with a history of higher rates of Apgar<75mins maintained higher Apgar rates during the study (OR=2.09 (1.28 to 3.41)) compared with units with pre-study rates aligned to the national rate. CONCLUSIONS PROMPT training, as implemented, had no effect on the rate of Apgar <75mins in Scotland during the study period. Local implementation at scale was found to be more difficult than anticipated. Further research is required to understand why the positive effects observed in other single-unit studies have not been replicated in Scottish maternity units, and how units can be best supported to locally implement the intervention authentically and effectively.

Abstract
PURPOSE Shoulder dystocia is the strongest known risk factor for brachial plexus birth palsy (BPBP). Fractures of the clavicle are known to occur in the setting of shoulder dystocia. It remains unknown whether a clavicle fracture that occurs during a birth delivery with shoulder dystocia increases the risk of BPBP or, alternatively, is protective. The purpose of this study was to use a large, national database to determine whether a clavicle fracture in the setting of shoulder dystocia is associated with an increased or decreased risk of BPBP. MATERIALS AND METHODS The 1997 to 2012 Kids' Inpatient Database (KID) was analyzed for this study. International Classification of Diseases, Ninth Revision (ICD-9) codes were used to identify newborns diagnosed with shoulder dystocia and BPBP as well as a concurrent fracture of the clavicle. Newborns with shoulder dystocia were stratified into 2 groups: dystocia without a clavicle fracture and dystocia with a clavicle fracture. Multivariable logistic regression was used to quantify the risk for BPBP among shoulder dystocia subgroups. RESULTS The dataset included 5,564,628 sample births extrapolated to 23,385,597 population births over the 16-year study period. A BPBP occurred at a rate of 1.2 per 1,000 births. Shoulder dystocia complicated 18.8% of births with a BPBP. A total of 7.84% of newborns with a BPBP also sustained a clavicle fracture. Births with shoulder dystocia and a clavicle fracture incurred BPBP at a rate similar to that for newborns with shoulder dystocia and no fracture (9.82% vs 11.77%). Shoulder dystocia without a concurrent clavicle fracture was an independent risk factor for BPBP (odds ratio, 112.1; 95% confidence interval, 103.5-121.4). Those with shoulder dystocia and clavicle fracture had a risk for BPBP comparable with those with shoulder dystocia but no fracture (odds ratio, 126.7 vs 112.1). CONCLUSIONS This population-level investigation suggests that, among newborns with shoulder dystocia, clavicle fracture is not associated with a significant change in the risk of BPBP. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic II.

Abstract
STATEMENT Mastery of shoulder dystocia management skills acquired via simulation training can reduce neonatal brachial plexus injury by 66% to 90%. However, the correlation between simulation drills and reduction in clinical injuries has been inconsistently replicated, and establishing a causal relationship between simulation training and reduction of adverse clinical events from shoulder dystocia is infeasible due to ethical limitations. Nevertheless, professional liability insurance carriers increasingly are mandating simulation-based rehearsal and competency assessment of their covered obstetric providers' shoulder dystocia management skills-a high-stakes demand that will require rapid scaling up of access to quality shoulder dystocia simulation. However, questions remain about differing simulation training schemes and instructional content used among clinically effective and ineffective educational interventions. This review of original research compares curricular content of shoulder dystocia simulation and reveals several critical gaps: (1) prescriptive instruction prioritizing maneuvers shown to decrease strain on the brachial plexus is inconsistently used. (2) Proscriptive instruction to avoid placing excessive and laterally directed traction on the head or to observe a brief hands-off period before attempting traction is infrequently explicit. (3) Neither relative effectiveness nor potential interaction between prescriptive and proscriptive elements of instruction has been examined directly. (4) Reliability of high-fidelity mannequins capable of objective measurement of clinician-applied traction force as compared with subjective assessment of provider competence is unknown. Further study is needed to address these gaps and inform efficient and effective implementation of clinically translatable shoulder dystocia simulation.

Abstract
BackgroundShoulder dystocia is an obstetrical emergency that requires immediate and appropriate provider response to decrease neonatal morbidity.ObjectiveTo determine whether institution of shoulder dystocia simulation training improves maternal and neonatal outcomes at delivery.Study designThis retrospective cohort study compared maternal and neonatal outcomes before (1 September 2008–31 December 2009) and after (1 January 2010–31 December 2014) a mandatory shoulder dystocia simulation curriculum was instituted. Χ2 and Fisher’s exact tests along with multivariate logistic regression models were conducted to adjust for potential confounding.ResultsOf 8930 vaginal deliveries that met eligibility criteria over the 6-year period, 299 (3.3%) deliveries were complicated by a shoulder dystocia. The adjusted frequency of shoulder dystocia was approximately two times higher after training implementation (1.9% vs 3.8%; adjusted OR=1.80 (1.23 to 2.65), p=0.003). Neonatal outcomes such as brachial plexus injury (5.0% vs 7.7%; p=0.75), clavicle fracture (5.0% vs 4.6%; p=1.00) and humerus fracture (0.0% vs 1.9%; p=1.00) were not statistically different after training. Additionally, no significant differences in episiotomy (5.0% vs 4.6%; p=1.00), postpartum haemorrhage (10.0% vs 12.4%; p=0.80) and severe perineal laceration (10.0% vs 6.6%; p=0.50) were observed.ConclusionsThe overall frequency of shoulder dystocia reportedly doubled after training despite stable operative vaginal delivery and caesarean delivery rates. No significant improvements were seen in maternal or neonatal outcomes after simulation training. As shoulder dystocias are rare events, simulation training may not necessarily improve neonatal outcomes, but it may increase overall provider awareness and intervention.

Abstract
OBJECTIVE To describe the adaptation of an obstetric emergencies training program to align with local clinical practice. METHODS A feasibility study was conducted to investigate the potential implementation of the PRactical Obstetric Multi-Professional Training (PROMPT) program at eight urban tertiary hospitals in the Philippines. Multi-professional teams attended a 2-day course on September 23 and 24, 2015, that comprised a demonstration PROMPT course (day 1) and a Train-the-Trainers session (day 2). During a facilitated adaptation session, each team reviewed the PROMPT algorithms for eclampsia, severe pre-eclampsia, postpartum hemorrhage and sepsis. The teams marked steps concordant with local practice and identified differences with local practice. Suggested amendments were reviewed by the PROMPT project team, using clinical guidelines to support any adaptations. RESULTS The PROMPT algorithm for initial management of eclampsia was used as an exemplar. Five of the nine management steps were concordant with local practice: support; airway; breathing; circulation; and control seizures. Amendments were successfully implemented for the following steps: call for help; magnesium sulfate loading dose; and magnesium sulfate maintenance dose. CONCLUSION Rapid and efficient adaptation of PROMPT training materials for use in the Philippines was possible using a facilitated and focused approach, utilizing the expertise of a representative mix of local healthcare professionals and evidence-based guidelines.

Abstract
The development of video tutorials is flourishing and may make it possible to maintain knowledge learned during instruction with simulation. The aim of this study was to assess the effect of adding a video tutorial to a lecture and simulation for learning the maneuvers and protocol for the management of shoulder dystocia. Student midwives and medical students attended a lecture class including instruction about maneuvers and a presentation of an algorithm for the management of shoulder dystocia. They were randomized into two groups. The video group was reminded every two weeks to watch a short tutorial. The control group was reminded to consult the slide show. At the end of two months, they were evaluated by graders. The practice, theory, and global scores of the students in the video group were significantly higher than those of the students in the control group (14.8 vs. 10.4; 5.6 vs. 3.4; and 9.3 vs. 7.0, P<0.001). The scores for the video group improved at the second simulation session, compared with the first (14.8 vs. 9.9; 5.6 vs. 2.9; and 9.3 vs. 7, P<0.001). The addition of a video tutorial improved learning compared to a standard lecture and simulation session alone.

Abstract
Background Many adverse pregnancy outcomes in the UK could be prevented with better intrapartum care. Training for intrapartum emergencies has been widely recommended but there are conflicting data about their effectiveness. Observational studies have shown sustained local improvements in perinatal outcomes associated with the use of the PRactical Obstetric Multi-Professional Training – (PROMPT) training package. However this effect needs to be investigated in the context of randomised study design in settings other than enthusiastic early adopter single-centres. The main aim of this study is to determine the effectiveness of PROMPT to reduce the rate of term infants born with low APGAR scores. Methods THISTLE (Trial of Hands-on Interprofessional Simulation Training for Local Emergencies) is a multi-centre stepped-wedge clustered randomised controlled superiority trial conducted across 12 large Maternity Units in Scotland. On the basis of prior observational findings all Units have been offered the intervention and have been randomly allocated in groups of four Units, to one of three intervention time periods, each six months apart. Teams of four multi-professional clinicians from each participating Unit attended a two-day PROMPT Train the Trainers (T3) programme prior to the start of their allocated intervention step. Following the T3 training, the teams commenced the implementation of local intrapartum emergency training in their own Units by the start of their allocated intervention period. Blinding has not been possible due to the nature of the intervention. The aim of the study is to follow up each Unit for at least 12-months after they have commenced their local courses. The primary outcome for the study is the proportion of Apgar scores <7 at 5 min for term vaginal or emergency caesarean section births (≥37 weeks) occurring in each of the study Units. These data will be extracted from the Information Services Division Scottish Morbidity Record 02, a national routine data collection on pregnancy and births. Mixed or marginal logistic regression will be employed for the main analysis. Discussion THISTLE is the first stepped wedge cluster randomised trial to evaluate the effectiveness of an intrapartum emergencies training programme. The results will inform training, trainers and policy going forward. Trial registration ISRCTN11640515 (registered on 09/09/2013).

Abstract
INTRODUCTION We aim to outline the annual cost of setting up and running a standard, local, multi-professional obstetric emergencies training course, PROMPT (PRactical Obstetric Multi-Professional Training), at Southmead Hospital, Bristol, UK - a unit caring for approximately 6500 births per year. MATERIAL AND METHODS A retrospective, micro-costing analysis was performed. Start-up costs included purchasing training mannequins and teaching props, printing of training materials and assembly of emergency boxes (real and training). The variable costs included administration time, room hire, additional printing and the cost of releasing all maternity staff in the unit, either as attendees or trainers. Potential, extra start-up costs for maternity units without established training were also included. RESULTS The start-up costs were €5574 and the variable costs for 1 year were €143 232. The total cost of establishing and running training at Southmead for 1 year was €148 806. Releasing staff as attendees or trainers accounted for 89% of the total first year costs, and 92% of the variable costs. The cost of running training in a maternity unit with around 6500 births per year was approximately €23 000 per 1000 births for the first year and around €22 000 per 1000 births in subsequent years. CONCLUSIONS The cost of local, multi-professional obstetric emergencies training is not cheap, with staff costs potentially representing over 90% of the total expenditure. It is therefore vital that organizations consider the clinical effectiveness of local training packages before implementing them, to ensure the optimal allocation of finite healthcare budgets.

Abstract
OBJECTIVE To evaluate whether a standardized approach to identify pregnant women at risk for shoulder dystocia (SD) is associated with reduced incidence of SD and brachial plexus injury (BPI). METHODS Between 2011 and 2015, prospective data were collected from 29 community-based hospitals in the USA during implementation of an evidence-based practice bundle, including an admission risk assessment, required "timeout" before operative vaginal delivery (OVD), and low-fidelity SD drills. All women with singleton vertex pregnancies admitted for vaginal delivery were included. Rates of SD, BPI, OVD, and cesarean delivery were compared between a baseline period (January 2011-September 2013) and an intervention period (October 2013-June 2015), during which there was a system-wide average bundle compliance of 90%. RESULTS There was a significant reduction in the incidence of SD (17.6%; P=0.028), BPI (28.6%; P=0.018), and OVD (18.0%; P<0.001) after implementation of the evidence-based practice bundle. There was a nonsignificant reduction in primary (P=0.823) and total (P=0.396) cesarean rates, but no association between SD drills and incidence of BPI. CONCLUSION Implementation of a standard evidence-based practice bundle was found to be associated with a significant reduction in the incidence of SD and BPI. Utilization of low-fidelity drills was not associated with a reduction in BPI.

BMC Pregnancy Childbirth 2016; 16:334.

Abstract
BACKGROUND McRoberts' and suprapubic pressure are often recommended as the initial choices of manoeuvres to manage shoulder dystocia, as they are believed to be less invasive compared to other manoeuvres. However, their success rates range from 23 to 40 %. This study aims to investigate the predictive factors for the success of McRoberts' manoeuvre with or without suprapubic pressure (M+/-S). METHODS All cases of shoulder dystocia in a tertiary hospital in South East Asia were recruited from 1995 to 2009. Subjects were analysed according to either 'success' or 'failure' of M+/-S. Maternal and fetal antenatal and intrapartum factors were compared by univariate and multivariate analysis. RESULTS Among 198 cases of shoulder dystocia, M+/-S as the primary manoeuvre was successful in 25.8 %. The other 74.2 % needed either rotational or posterior arm manoeuvres or combination of manoeuvres. Instrumental delivery was the single most significant factor associated with an increased risk of failed M+/-S on logistic regression (p < 0.001, OR 4.88, 95 % CI 2.05-11.60). The success rate of M+/-S was only 15.0 % if shoulder dystocia occurred after instrumental delivery but was 47.7 % after spontaneous vaginal delivery. CONCLUSIONS When shoulder dystocia occurs after instrumental vaginal delivery, the chance of failure of M+/-S is 85 %, which is 4.7 times higher than that after spontaneous vaginal delivery. Hence all operators performing instrumental delivery should be proficient in performing all manoeuvres to relieve shoulder dystocia when M+/-S cannot do so.

Abstract
Perinatal asphyxia is a general term referring to neonatal encephalopathy related to events during birth. Asphyxia refers to a deprivation of oxygen for a duration sufficient to cause neurologic injury. Most cases of perinatal asphyxia are not necessarily caused by intrapartum events but rather associated with underlying chronic maternal or fetal conditions. Of intrapartum causes, obstetric emergencies are the most common and are not always preventable. Screening high-risk pregnancies with ultrasound, Doppler velocimetry, and antenatal testing can aid in identifying fetuses at risk. Interventions such as intrauterine resuscitation or operative delivery may decrease the risk of severe hypoxia from intrauterine insults and improve long-term neurologic outcomes.

Abstract
Shoulder dystocia is a complication of vaginal delivery and the primary factor associated with brachial plexus injury. In this review, we discuss the risk factors for shoulder dystocia and propose a framework for the prediction and prevention of the complication. A recommended approach to management when shoulder dystocia occurs is outlined, with review of the maneuvers used to relieve the obstruction with minimal risk of fetal and maternal injury.

Abstract
IMPORTANCE Shoulder dystocia is an obstetric emergency with potential catastrophic outcomes. OBJECTIVE To perform a systematic literature review examining the effectiveness of episiotomy in the prevention and management of shoulder dystocia during vaginal birth. EVIDENCE ACQUISITION Search was conducted by a research librarian in MEDLINE, Web of Science, Cochrane Library, and SCOPUS databases using the terms "episiotomy" and "shoulder dystocia," with no language or time restrictions. Two investigators independently selected original researches examining the effects of episiotomy on shoulder dystocia and its neonatal andmaternal outcomes. Relevant articles were accessed in full text, including manual search of the references. We contacted authors of studies with insufficient or unclear data. Because of clinical and methodological diversity of the studies, meta-analysis was not performed. RESULTS Fourteen articles met the inclusion criteria, encompassing a total of 9769 shoulder dystocia cases. Only 1 study effectively evaluated the role of episiotomy in shoulder dystocia prevention, yielding a nonsignificant result. Three articles assessed neonatal consequences of shoulder dystocia, one of them linking episiotomy to higher risk of neonatal injury. Two of the 3 studies evaluating maternal outcomes showed that episiotomy is related to increased risk of advanced perineal tears. Overall quality of evidence was rated as very low. CONCLUSIONS AND RELEVANCE Our systematic review found no evidence supporting the use of episiotomy in the prevention and management of shoulder dystocia. This observation carries major clinical and legal implications for the obstetricians. Higher-quality studies are needed to evaluate this important issue.

Abstract
OBJECTIVE Birth is less safe than it can be. We adapted the UK-developed PROMPT (PRactical Obstetric Multi-Professional Training) course to local practices and initiated annual training. STUDY DESIGN This observational study used quality assurance data from University of Kansas Hospital 2 years before and 7 years after intervention encompassing 14,309 consecutive deliveries from January 2006 through December 2014. An events/trials approach was applied to changes in proportions over time. RESULT PROMPT was associated with progressive decreases in rates (P<0.05) of brachial plexus injury and umbilical artery pH <7.00 exclusive of catastrophic events. Reduced rates (P<0.05) of cesarean section, episiotomy and higher perception of nurse/physician communication were documented. Hypoxic ischemic encephalopathy (HIE) rates declined progressively by >50% (P=NS). These improvements occurred despite younger faculty and higher rates of complicated pregnancies (P<0.05). Estimated health-care costs avoided exceeded annual training costs. CONCLUSION Local annual multi-professional training as provided by PROMPT was temporally associated with improved obstetric outcomes.

Abstract
OBJECTIVE The objective of this review is to propose recommendations on the management of shoulder dystocia. MATERIALS AND METHODS The PubMed database, the Cochrane Library and the recommendations from the foreign obstetrical societies or colleges have been consulted. RESULTS In case of shoulder dystocia, if the obstetrician is not present at delivery, he should be systematically informed as quickly as possible (professional consensus). A third person should also be called for help in order to realize McRoberts maneuver (professional consensus). The patient has to be properly installed in gynecological position (professional consensus). It is recommended not to pull excessively on the fetal head (grade C), do not perform uterine expression (grade C) and do not realize inverse rotation of the fetal head (professional consensus). McRoberts maneuver, with or without a suprapubic pressure, is simple to perform, effective and associated with low morbidity, thus, it is recommended in the first line (grade C). Regarding the maneuvers of the second line, the available data do not suggest the superiority of one maneuver in relation to another (grade C). We proposed an algorithm; however, management should be adapted to the experience of the operator. If the posterior shoulder is engaged, Wood's maneuver should be performed preferentially; if the posterior shoulder is not engaged, delivery of the posterior arm should be performed preferentially (professional consensus). Routine episiotomy is not recommended in shoulder dystocia (professional consensus). Other second intention maneuvers are described. It seems necessary to know at least two maneuvers to perform in case of shoulder dystocia unresolved by the maneuver McRoberts (professional consensus). CONCLUSION All physicians and midwives should know and perform obstetric maneuvers if needed quickly but without precipitation.

Abstract
OBJECTIVE To describe neonatal complications related to shoulder dystocia. METHODS This systematic evidence review is based on PubMed search, Cochrane library and experts' recommendations. RESULTS The risks of brachial plexus birth injury, clavicle and humeral fracture, perinatal asphyxia, hypoxic-ischemic encephalopathy and perinatal mortality are increased after shoulder dystocia. The medical team should be able to provide neonatal resuscitation in the delivery room in case of perinatal asphyxia following shoulder dystocia, according to national and international guidelines. The initial clinical examination should search for complications such as brachial plexus birth injury or clavicle fracture. CONCLUSION The risk of perinatal complications is increased in newborn after shoulder dystocia. The medical team should be able to manage these complications.

Abstract
OBJECTIVES To synthetize the available evidence regarding the incidence and risk factors of shoulder dystocia (SD). METHODS Consultation of the Medline database, and of national guidelines. RESULTS Shoulder dystocia is defined as a vaginal delivery that requires additional obstetric manoeuvres to deliver the foetus after the head has delivered and gentle traction has failed. With this definition, the incidence of SD in population-based studies is about 0.5-1% of vaginal deliveries. Many risk factors have been described but most associations are not independent, or have not been constantly found. The 2 characteristics consistently found as independent risk factors for SD in the literature are previous SD (incidence of SD of about 10% in parturients with previous SD) and foetal macrosomia. Maternal diabetes and obesity also are associated with a higher risk of SD (2 to 4 folds) but these associations may be completely explained by foetal macrosomia. However, even factors independently and constantly associated with SD do not allow a valid prediction of SD because they are not discriminant; 50 to 70% of SD cases occur in their absence, and the great majority of deliveries when they are present is not associated with SD. CONCLUSION Shoulder dystocia is defined by the need for additional obstetric manoeuvres to deliver the foetus after the head has delivered and gentle traction has failed, and complicates 0.5-1% of vaginal deliveries. Its main risk factors are previous SD and macrosomia, but they are poorly predictive. SD remains a non-predictable obstetrics emergency. Knowledge of SD risk factors should increase the vigilance of clinicians in at-risk contexts.

Abstract
Multidisciplinary training has improved maternity outcomes when the training has been well attended, regular, in house, used high-fidelity simulators, and integrated teamwork training. If these principles were used in other settings, better clinical care may result. This before-after study sought to establish whether a short multidisciplinary training intervention can improve recognition of the deteriorating patient using an aggregated physiological parameter scoring system (Early Warning Score [EWS]). Nursing, medical, and allied nursing staff participated in an hour-long training session, using real-life scenarios with simple tools and structured debriefing. After training, staff were more likely to calculate EWS scores correctly (68.02% vs 55.12%; risk ratio [RR] = 1.24, 95% confidence interval [CI] = 1.07-1.44), and observations were more likely to be performed at the correct frequency (78.57% vs 68.09%; RR = 1.20, 95% CI = 1.09-1.32). Multidisciplinary training, according to core principles, can lead to more accurate identification of deteriorating patients, with implications for subsequent care and outcome.
