Shoulder dystocia: simulation and a team-centered protocol

The utility of bedside simulation for training in critical care obstetrics

Over the last 2 decades, the maternal mortality ratio in the United States has doubled from 7.4/100,000 live births in 1986 to 14.5/100,000 today. Despite great advances in health care, increasing rates of maternal morbidity and mortality in the United States have prompted calls to action to reverse this disturbing trend. Assisted reproductive technology has allowed women to delay childbearing to more advanced ages, resulting in a greater number of pregnancies complicated by one or more of the diseases associated with aging, such as cardiovascular disease, cancer, type 2 diabetes, and hypertension. The obesity epidemic, increasing rates of chronic diseases affecting pregnancy, steadily rising cesarean delivery rate with resulting complications, and medical advances allowing women with rare, but serious diseases to conceive contribute to rising maternal morbidity and mortality rates. Obstetric critical care simulation training may result in improved multidisciplinary teamwork and patient outcomes; and fewer medical and communication errors.

Strategies to Improve Management of Shoulder Dystocia Under the AHRQ Safety Program for Perinatal Care

OBJECTIVE

To assess implementation of safety strategies to improve management of births complicated by shoulder dystocia in labor and delivery units.

DESIGN

Mixed-methods implementation evaluation.

SETTING/LOCAL PROBLEM

Labor and delivery units (N = 18) in 10 states participating in the Safety Program for Perinatal Care (SPPC). Shoulder dystocia is unpredictable, requiring rapid and coordinated action.

PARTICIPANTS

Key informants were labor and delivery unit staff who implemented SPPC safety strategies.

INTERVENTION/MEASUREMENTS

The SPPC was implemented by using the TeamSTEPPS teamwork and communication framework and tools, applying safety science principles (standardization, independent checks, and learn from defects) to shoulder dystocia management, and establishing an in situ simulation program focused on shoulder dystocia to practice teamwork and communication skills. Unit staff received training, a toolkit, technical assistance, and unit-specific feedback reports. Quantitative data on unit-reported process improvement measures and qualitative data from staff interviews were used to understand changes in use of safety principles, teamwork/communication, and in situ simulation.

RESULTS

Use of shoulder dystocia safety strategies improved on the units. Differences between baseline and follow-up (10 months) were as follows: in situ simulation (50% vs. 89%), teamwork and communication (67% vs. 94%), standardization (67% to 94%), learning from defects (67% vs. 89%), and independent checks (56% vs. 78%). Interview data showed reasons to address management of shoulder dystocia, various approaches to implement safety practices, and facilitators and barriers to implementation.

CONCLUSION

Successful management of shoulder dystocia requires a rapid, standardized, and coordinated response. The SPPC strategies to increase safety of shoulder dystocia management are scalable, replicable, and adaptable to unit needs and circumstances.

Randomised controlled study to assess skill retention at 6 vs 12 months after simulation training in shoulder dystocia

Introduction

Current evidence suggests annual training in the management of shoulder dystocia is adequate. The aim of this trial is to test our hypothesis that skills start to decline at 6 months after training and further decline at 12 months.

Methods

In this randomised, single-blinded study, 13 obstetricians and 51 midwives were randomly assigned to attend a 1-hour mixed lecture and simulation session on shoulder dystocia management. Training was conducted on group 2 at month ‘0’ and on group 1 at month ‘6’. Their knowledge scores (primary outcome) were assessed before (pre-training), immediately after the training (at-training) and retested at month ‘12’ (post-training).

Results

Two-way repeated-measures analysis of variance showed a statistically significant interaction between the testing time frame (pre-training, at-training and post-training) on the score (p<0.001), but no significant interaction between the groups on the score (p=0.458).

Compared to pre-training, the score increased after the simulation training (at-training) in both group 1 (8.69 vs 14.34, p<0.001) and group 2 (9.53 vs 14.66, p< 0.001), but decreased at 6 months post- training in group 1 (14.34 vs 11.71, p<0.001) and at 12 months post-training in group 2 (14.66 vs 11.96, p< 0.001). However the score was better than before the training. There was no significant difference in the post –training score (11.71vs 11.96, p=0.684) between both groups.

Conclusions

Our study demonstrated that simulation training results in short-term and long-term improvement in shoulder dystocia management however knowledge degrades over time. Ongoing training is suggested at a minimum of 12 months’ interval for all members of the obstetrics team including midwives and doctors.

Implementation of a multicenter shoulder dystocia injury prevention program

Although the evidence for supporting the effectiveness of many patient safety practices has increased in recent years, the ability to implement programs to positively impact clinical outcomes across multiple institutions is lagging. Shoulder dystocia simulation has been shown to reduce avoidable patient harm. Neonatal injury from shoulder dystocia contributes to a significant percentage of liability claims. We describe the development and the process of implementation of a shoulder dystocia simulation program across five academic medical centers and their affiliated hospitals united by a common insurance carrier. Key factors in successful roll out of this program included the following: involvement of physician and nursing leadership from each academic medical center; administrative and logistic support from the insurer; development of consensus on curriculum components of the program; conduct of gap and barrier analysis; financial support from insurer to close necessary gaps and mitigate barriers; and creation of dashboards and tracking performance of the program.

[Macrosomia, shoulder dystocia and elongation of the brachial plexus: what is the role of caesarean section?]

The delivery of a macrosomic infant is associated with a higher risk for maternofoetal complications. Shoulder dystocia is the most feared fetal complication, leading sometimes to a disproportionate use of caesarean section. This study aims to evaluate the interest of preventive caesarean section. We conducted a retrospective study of 400 macrosomic births between February 2010 and December 2012. We also identified cases of infants with shoulder dystocia occurred in 2012 as well as their respective birthweight. Macrosomic infants weighed between 4000g and 4500g in 86.25% of cases and between 4500 and 5000 in 12.25% of cases. Vaginal delivery was performed in 68% of cases. Out of 400 macrosomic births, 9 cases with shoulder dystocia were recorded (2.25%). All of these cases occurred during vaginal delivery. The risk for shoulder dystocia invaginal delivery has increased significantly with the increase in birth weight (p <10-4). The risk for elongation of the brachial plexus was 11 per thousand vaginal deliveries of macrosomic infants. This risk was not correlated with birthweight (p = 0.38). The risk for post-traumatic sequelae was 0.71%. Shoulder dystocia affectd macrosoic infants in 58% of cases. Shoulder dystocia is not a complication exclusively associated with macrosomia. Screening for risky deliveries and increasing training of obstetricians on maneuvers in shoulder dystocia seem to be the best way to avoid complications.

Shoulder Dystocia: Quality, Safety, and Risk Management Considerations

Shoulder dystocia is a term that evokes terror and fear among many physicians, midwives, and health care providers as they recollect at least 1 episode of shoulder dystocia in their careers. Shoulder dystocia can result in significant maternal and neonatal complications. Because shoulder dystocia is an urgent, unanticipated, and uncommon event with potentially catastrophic consequences, all practitioners and health care teams must be well-trained to manage this obstetric emergency. Preparation for shoulder dystocia in a systematic way, through standardization of process, practicing team-training and communication, along with technical skills, through simulation education and ongoing quality improvement initiatives will result in improved outcomes.

[The Jacquemier's maneuver: An overview of midwives knowledge and practices in a third level maternity hospital]

OBJECTIVES

Shoulder dystocia is an uncommon but serious complication occurring in 0.2 to 3% of deliveries. We carried out a study in order to assess the midwives experience, knowledge and practices on shoulder dystocia, at the maternity hospital of Saint-Denis, Reunion Island.

METHODS

The first part is a confidential questionnaire addressed to midwives working in the delivery unit. The second part is a retrospective desk review of shoulders dystocia which occurred from 2004 to 2014.

RESULTS

(1) The population was made up of 28 midwives, having between 1 to 27 years of experience. Seventy-five percent of them had been faced with shoulder dystocia, and 62% had realized Jacquemier's maneuver. However, only 25% received this maneuver training. Less than a third of them answered correctly to at least 7 from the 8 theoretical questions about the Jacquemier's maneuver. (2) We studied 34 shoulders dystocia, occurring between 36+5 to 41+2 gestational weeks, mostly with no risk factors found. Mac Roberts' maneuver is used as first-line in 88% of situations. Jacquemier's maneuver is used in 52.9% of cases (5.9% as first-line, 47% as second-line). In 26.4% of situations, the midwife is not able to reduce the dystocia. She usually carries out a combination of maneuvers. The gynecologist is asked only for 23.5% of dystocia and he usually uses Jacquemier's maneuver (70% of situations).

CONCLUSION

The Jacquemier's maneuver is rarely practiced (uncommon situation, lack of training). Simulation trainings should be put in place, because neonatal sequels can be avoided.

Effectiveness of team training in managing shoulder dystocia: a retrospective study

OBJECTIVES

To evaluate the effectiveness of simulation team training for the management of shoulder dystocia. Primary outcome measures were the number of reported cases of shoulder dystocia, as well as fetal injury that occurred from it. Secondary outcome is documentation of manoeuvres used to alleviate shoulder dystocia.

METHODS

Retrospective cohort study in a teaching hospital in the Netherlands, in a 38 month period before and after implementation of team training.

RESULTS

We compared 3492 term vaginal cephalic deliveries with 3496 deliveries before and after team training. Incidence of shoulder dystocia increased from 51 to 90 cases (RR 1.8 (95% CI: 1.3-2.5)). Fetal injury occurred in 16 and eight cases, respectively (RR 0.50 (95% CI: 0.21-1.2)). Before team training started, the all-fours manoeuvre was never used, while after team training it was used in 41 of 90 cases (45%). Proper documentation of all manoeuvres used to alleviate shoulder dystocia significantly increased after team training (RR 1.6 (95% CI: 1.05-2.5)).

CONCLUSIONS

Simulation team training increased the frequency of shoulder dystocia, facilitated implementation of the all-fours technique, improved documentation of delivery notes and may have a beneficial effect on the number of children injured due to shoulder dystocia.

[Assessment of shoulder dystocia related knowledge among French obstetrics and gynecology residents]

OBJECTIVE

To study the related knowledge of French residents in obstetrics concerning maneuvers for shoulder dystocia (SD).

MATERIALS AND METHODS

Multicenter descriptive transversal study conducted from June to September 2014. Data collection was performed through questionnaires sent by email to French resident in obstetrics.

RESULTS

Among the 1080 questionnaires sent, 366 responses were obtained with a response rate of 33.9%. One hundred and forty-three residents (39.1%) were in the first part of their training (≤5th semester) and 60.9% (n=223) were in the second part of their training. Theoretical training on the SD was provided to 88.2% of resident (n=323). In total, 38.8% (n=142) obtained their French degree in mechanical and technical obstetric and among them 77.5% (n=110) had the opportunity to train on simulators and dummies. Concerning their practical experiences, 31.5% (n=45) residents ≤5th semester reported having experienced SD during their residency vs 58.3% (n=130) amongst oldest residents (P<0.001). In the second part of residency, 40% of residents (n=89) expressed to feel able to manage shoulder dystocia. Only 19.1% (n=70) were satisfied with their residency training program vs 39.1% (n=143) who were unsatisfied.

CONCLUSION

Our study showed that less than one resident out of two (40%) felt able to perform maneuvers for SD in the second part of residency. We think that simulation activities should be mandatory for residency training programs in Obstetrics and Gynecology, which have to develop dependable measures to assess resident competencies to execute practical maneuvers for clinical emergencies in obstetrics.

Center of excellence for placenta accreta

Placenta accreta spectrum is one of the most morbid conditions obstetricians will encounter. The incidence has dramatically increased in the last 20 years. The major contributing factor to this is believed to be the increase in the rate of cesarean delivery. Despite the increased incidence of placenta accreta, most obstetricians have personally managed only a small number of women with placenta accreta. The condition poses dramatic risk for massive hemorrhage and associated complication such as consumption coagulopathy, multisystem organ failure, and death. In addition, there is an increased risk for surgical complications such as injury to bladder, ureters, and bowel and the need for reoperation. Most women require blood transfusion, often in large quantities, and many require admission to an intensive care unit. As a result of indicated, often emergent preterm delivery, many babies require admission to a neonatal care intensive care unit. Outcomes are improved when delivery is accomplished in centers with multidisciplinary expertise and experience in the care of placenta accreta. Such expertise may include maternal-fetal medicine, gynecologic surgery, gynecologic oncology, vascular, trauma and urologic surgery, transfusion medicine, intensivists, neonatologists, interventional radiologists, anesthesiologists, specialized nursing staff, and ancillary personnel. This article highlights the desired features for a center of excellence in placenta accreta, and which patients should be referred for evaluation and/or delivery in such centers.
