Can inter-professional simulation training influence the frequency of blood transfusions after birth?

Interprofessional obstetric simulation training improves postpartum haemorrhage management and decreases maternal morbidity: a before-and-after study

OBJECTIVE

To determine the impact of the Obstetric Simulation Training and Teamwork (OB-STaT) curriculum on postpartum haemorrhage (PPH) rates and outcomes.

DESIGN

Before-and-after study.

SETTING

Maternity care hospitals within the USA.

POPULATION

Patients who delivered between February 2018 and November 2019.

METHODS

Interprofessional obstetric teamwork training (OB-STaT) conducted at each hospital. Electronic medical records for deliveries were reviewed for 6 months before and after conducting OB-STaT at participating hospitals.

MAIN OUTCOME MEASURES

The PPH rate (blood loss of ≥1000 ml), uterotonic medications used, tranexamic acid use, blood product transfusion, hysterectomy, length of stay and composite maternal morbidity (postpartum haemorrhage, hysterectomy, transfusion of ≥4 units of blood products and intensive care unit admission for PPH).

RESULTS

A total of 9980 deliveries were analysed: 5059 before and 4921 after OB-STaT. The PPH rates did not change significantly (5.48% before vs 5.14% after, p = 0.46). Composite maternal morbidity decreased significantly by 1.1% (6.35%-5.28%, p = 0.03), massive transfusions decreased by 57% (0.42%-0.18%, p = 0.04) and the mean postpartum length of stay decreased from 2.05 days (1.05 days SD) to 2.01 days (0.91 days SD) (p = 0.04). Following OB-STaT, haemorrhage medication use increased by 36% (14.8%-51.2%, p = 0.03), the use of tranexamic acid for PPH treatment almost doubled (2.7%-4.8%, p < 0.001) and the rate of hysterectomy significantly increased (0%-0.1%, p = 0.03).

CONCLUSIONS

Although the PPH rates did not decrease, OB-STaT significantly improved maternal morbidity, decreased massive transfusions, and improved PPH management by increasing the utilization of uterotonic medications, tranexamic acid and hysterectomy.

Integration of simulation-based education in anaesthesiology specialist training: Synthesis of results from an Utstein Meeting

BACKGROUND

Despite its importance in education and patient safety, simulation-based education and training (SBET) is only partially or poorly implemented in many countries, including most European countries. The provision of a roadmap may contribute to the development of SBET for the training of anaesthesiologists.

OBJECTIVE

To develop a global agenda for the integration of simulation into anaesthesiology specialist training; identify the learning domains and objectives that are best achieved through SBET; and to provide examples of simulation modalities and evaluation methods for these learning objectives.

DESIGN

Utstein-style meeting where an expert consensus was reached after a series of short plenary presentations followed by small group workshops, underpinned by Kern's six-step theoretical approach to curriculum development.

SETTING

Utstein-style collaborative meeting.

PARTICIPANTS

Twenty-five participants from 22 countries, including 23 international experts in simulation and two anaesthesia trainees.

RESULTS

We identified the following ten domains of expertise for which SBET should be used to achieve the desired training outcomes: boot camp/initial training, airway management, regional anaesthesia, point of care ultrasound, obstetrics anaesthesia, paediatric anaesthesia, trauma, intensive care, critical events in our specialty, and professionalism and difficult conversations. For each domain, we developed a course template that defines the learning objectives, instructional strategies (including simulation modalities and simulator types), and assessment methods. Aspects related to the practical implementation, barriers and facilitators of this program were also identified and discussed.

CONCLUSIONS

We successfully developed a comprehensive agenda to facilitate the integration of SBET into anaesthesiology specialist training. The combination of the six-step approach with the Utstein-style process proved to be extremely valuable in supporting content validity and representativeness. These results may facilitate the implementation and use of SBET in several countries.

Help a mother out: The impact of acute care surgeon response in postpartum hemorrhage

INTRODUCTION

A Code White (CW) activation is a hospital-wide alert for postpartum hemorrhage (PPH) and acute care surgeons (ACS) were added to the response team to assist in resuscitation. A multidisciplinary training program was also implemented. This study aimed to evaluate the impact of ACS involvement and training on maternal outcomes.

METHODS

A retrospective review was performed on all CW activations from 1/1/2015-8/31/2022. Three groups-pre-ACS response, ACS response, and ACS response ​+ ​training (R&T)-were compared.

RESULTS

218 patients had CW activations. ACS response increased MTP activations (50.0%vs76.5%vs76.2%, p ​= ​0.014) and TXA administration (50.0%vs96.5%vs93.3%, p ​< ​0.0001). The ACS R&T had the highest ACS presence (53.6%vs72.9%vs96.2%, p ​< ​0.0001), shortest operation (99 vs 67 vs 53min, p ​= ​0.002), lowest crystalloid use (2000 vs 1110 vs 800 ​ml, p ​= ​0.003), and lowest transfusion requirements. Mortality decreased from 17.9% in pre-ACS to 2.4% in ACS response and 0% in ACS R&T (p ​< ​0.0001).

CONCLUSION

ACS assistance in CW activations and multidisciplinary PPH education led to the prevention of maternal mortality. ACS are a valuable resource in this unique population.

Simulation to improve trainee knowledge and comfort in managing maternal cardiac arrest

BACKGROUND

Maternal cardiac arrest is a rare outcome, and thus there are limited opportunities for specialists in obstetrics and gynecology to acquire the skills required to respond to it through routine clinical practice.

OBJECTIVE

This study aimed to evaluate gaps in medical education in maternal cardiac arrest and whether a simulation-based training program improves resident knowledge and comfort in the diagnosis and treatment of maternal cardiac arrest.

STUDY DESIGN

A 2-hour training for obstetrics and gynecology residents at an academic medical center was conducted, consisting of a didactic presentation, defibrillator skills station, and 2 high-fidelity simulations. Consenting residents completed a 21-item pretest followed by a 12-item posttest exploring knowledge of and exposure to maternal cardiac arrest. The McNemar and Wilcoxon signed-rank tests were used to compare pre- and posttest data.

RESULTS

Of 21 residents, 15 (71.4%) had no previous education about maternal cardiac arrest, and 17 (81.0%) had never responded to a maternal code. Participants demonstrated increased knowledge about maternal cardiac arrest after the session, providing more correct answers on the reversible causes of pulseless electrical activity arrest (median 4 vs 7 correct responses; P<.01). After the training, more residents were able to identify the correct gestational age to perform a cesarean delivery during maternal cardiac arrest (19.0% vs 90.5%; P<.01) and the correct location for this procedure (52.4% vs 95.2%; P<.01). All residents reported that maternal cardiac arrest training was important and that they would benefit from additional sessions. Median composite comfort level in managing maternal cardiac arrest significantly increased after participation (pretest, 24.0 [interquartile range, 21.5-28.0]; posttest, 37.0 [interquartile range, 34.3-41.3]; P<.01).

CONCLUSION

Residents report limited exposure to maternal cardiac arrest and desire more training. Simulation-based training about maternal cardiac arrest is needed during residency to ensure that graduates are prepared to respond to this high-acuity event.

Simulation-based training in obstetric anesthesia: an update

In this update we explore the current applications of simulation in obstetric anesthesia, describe what is known regarding its impacts on care and consider the different settings in which simulation programs are required. We will introduce practical strategies, such as cognitive aids and communication tools, that can be applied in the obstetric setting and share ways in which a program might apply these tools. Finally, we provide a list of common obstetric emergencies essential for a program's curriculum and common teamwork pitfalls to address within a comprehensive obstetric anesthesia simulation program.

Obstetric Simulation Training and Teamwork: Immediate Impact on Knowledge, Teamwork, and Adherence to Hemorrhage Protocols

INTRODUCTION

The Obstetric Simulation Training and Teamwork (OB-STaT) curriculum was an in situ interprofessional program to provide standardized postpartum hemorrhage (PPH) simulation training throughout a health system to decrease PPH morbidity. In this study portion, investigators hypothesized that OB-STaT would increase: (a) team member knowledge in diagnosis and management of PPH, (b) teamwork, (c) adherence to established PPH protocols, and (d) patient satisfaction.

METHODS

The OB-STaT was implemented at 8 US Navy hospitals between February 2018 and November 2019. Participant PPH treatment and maternal/neonatal resuscitation pretraining/posttraining knowledge was assessed via an 11-item test, whereas teamwork and standardized patient assessment were rated using validated Likert-type scales: the 15-item Clinical Teamwork Scale and 3-item Patient Perception Score, with item ranges of 0 to 10 and 0 to 5, respectively. Local PPH protocol adherence was assessed using role-specific checklists, with a potential maximum of 14 points (anesthesia/nursing) or 22 points (obstetrics).

RESULTS

Fifty-four interprofessional teams participated. Obstetricians (trainees and attendings) demonstrated significantly improved knowledge test scores (8.33 ± 1.6 vs. 8.66 ± 1.5, P < 0.01). Between the 2 scenarios, overall mean Clinical Teamwork Scale scores improved significantly for all interprofessional teams (5.82 ± 2.0 vs. 7.25 ± 1.9, P < 0.01). Anesthesia, nursing, and obstetric subteams demonstrated significant increases in protocol adherence as measured by critical action scores (12.28 ± 1.7 vs. 13.56 ± 1.0, 12.43 ± 1.6 vs. 13.14 ± 1.3, and 18.14 ± 2.7 vs. 19.56 ± 2.1 respectively, all P < 0.02). Although overall standardized patient satisfaction did not significantly improve, scores for feeling well informed did (3.36 ± 1.0 vs. 3.76 ± 0.8, P < 0.01).

CONCLUSIONS

The OB-STaT curriculum modestly improved participants' teamwork, communication, and protocol adherence during simulated PPH scenarios; OB-STaT may decrease PPH morbidity.

Tools for establishing a sustainable safety culture within maternity services. A retrospective case study

Objective:

This article reports the findings from a single case study on the long-term sustainability of a quality system in a large maternity unit.

Method:

The empirical basis is an analysis of documents related to the development, implementation, maintenance and outcome of the system over two decades. The main elements of the quality system are reported as findings, and the possible effects of the different elements are presented and discussed based on theories on safety management and leadership.

Result:

The findings suggest that the quality system served as the basis for a meaningful workplace community. The structure of meetings, research, training and budget input were all central factors for the development of the system. It resulted in systematic ongoing improvement, participation from all levels of the organization and trust within the organization. The effects of the system may still be seen after the end point of this study.

Conclusions:

It remains the responsibility of the management to ensure an adequate professional standard of services by a continuous internal quality assurance system for enhanced patient safety.

Postpartum hemorrhage drills or simulations and adverse outcomes: a systematic review and Bayesian meta-analysis

OBJECTIVE

To compare the rates of adverse outcomes with postpartum hemorrhage (PPH) before and after implementation of drills or simulation exercises.

STUDY ELIGIBILITY CRITERIA

We included all English studies that reported on rates of PPH and associated complications during the pre- and post-implementation of interventional exercises.

STUDY APPRASIAL AND SYNTHESIS METHODS

Two investigators independently reviewed the abstracts, and full articles for eligibility of all studies. Inconsistencies related to study evaluation or data extraction were resolved by a third author. The co-primary outcomes were the rate of PPH and of any transfusion; the secondary outcomes included admission to the intensive care unit (ICU), transfusion ≥ 4 units of packed red blood cells, hysterectomy, or maternal death. Study effects were combined by Bayesian meta-analysis and reported as risk ratios (RR) and 95% credible intervals (Cr).

RESULTS

We reviewed 142 full length articles. Of these, 18 publications, with 355,060 deliveries-150,562 (42%) deliveries during the pre-intervention and 204,498 (57.6%) deliveries in the post-interventional period-were included in the meta-analysis. Using the Newcastle-Ottawa Scale, only three studies were considered good quality, and none of them were done in the US. The rate of PPH prior to intervention was 5.06% and 5.46% afterwards (RR 1.09, 95% CI 0.87-1.36; probability of reduction in the diagnosis being 21%). The likelihood of transfusion decreased from 1.68% in the pre-intervention to 1.27% in the post-intervention period (RR 0.80, 95% Cr 0.57-1.09). The overall probability of reduction in transfusion was 93%, albeit it varied among studies done in non-US countries (96%) versus in the US (23%). Transfusion of 4 units or more of blood occurred in 0.44% of deliveries before intervention and 0.37% afterwards (RR of 0.85, 95% CI 0.50-1.52), with the overall probability of reduction being 72% (76% probability of reduction in studies from non-US countries and 49% reduction with reports from the US). Surgical interventions to manage PPH, which was not reported in any US studies, occurred in 0.14% before intervention and 0.28% afterwards (RR 1.29; 95% CI 0.56-3.06; probability of reduction 27%). Admission to the ICU occurred in 0.10% before intervention and 0.08% subsequently (RR 0.92, 95% CI 0.58-1.43), with the overall probability of reduction being 65% (81% in studies from non-US countries and 27% from the study done in the US). Maternal death occurred in 0.17% in the pre-intervention period and 0.09% during the post-intervention (RR 0.62, 95% CI 0.33-1.05; probability of reduction 93% in studies from non-US countries and 82% in one study from the US).

CONCLUSIONS

Interventions to reduce the sequelae of PPH are associated with decrease in adverse outcomes. The conclusion, however, ought not to be accepted reflexively for the US population. All of the studies on the topic done in the US are of poor quality and the associated probability of reduction in sequelae are consistently lower than those done in other countries.

SYNOPSIS

Since the putative benefits of PPH drills or simulation exercises are based on poor quality pre- and post-intervention trials, policies recommending them ought to be revisited.

Simulation in Obstetrics and Gynecology: A Review of the Past, Present, and Future

Simulation in obstetrics and gynecology has advanced significantly since its beginnings in the seventeenth century with wooden birthing and pelvic models. In recent years, more and more evidence has emerged showing improvements in participant confidence, skills, behaviors, and, finally, patient outcomes following simulation program implementation. Several regulatory bodies and national organizations have begun to require simulation of obstetrician-gynecologists, and the newer generation of physicians has experienced simulation throughout their training. Simulation is embedded in the medical culture and hopefully is making obstetrician-gynecologists better for it.

The effects of obstetric emergency team training on patient outcome: A systematic review and meta-analysis

INTRODUCTION

Little is known about the optimal simulation-based team training in obstetric emergencies. We aimed to review how simulation-based team training affects patient outcomes in obstetric emergencies.

MATERIAL AND METHODS

Search Strategy: MEDLINE, Embase, Cochrane Library, and Cochrane Central Register of Controlled Trials were searched up to and including May 15, 2021.

SELECTION CRITERIA

randomized controlled trials (RCTs) and cohort studies on obstetric teams in high-resource settings comparing the effect of simulation-based obstetric emergency team training with no training on the risk of Apgar scores less than 7 at 5 min, neonatal hypoxic ischemic encephalopathy, severe postpartum hemorrhage, blood transfusion of four or more units, and delay of emergency cesarean section by more than 30 min.

DATA COLLECTION AND ANALYSIS

The included studies were assessed using PRISMA, EPCO, and GRADE.

RESULTS

We found 21 studies, four RCTs and 17 cohort studies, evaluating patient outcomes after obstetric team training compared with no training. Annual obstetric emergency team training may reduce brachial plexus injury (six cohort studies: odds ratio [OR] 0.47, 95% CI 0.33-0.68; one RCT: OR 1.30, 95 CI% 0.39-4.33, low certainty evidence) and suggest a positive effect; but it was not significant on Apgar score below 7 at 5 min (three cohort studies: OR 0.77, 95% CI 0.51-1.19; two RCT: OR 0.87, 95% CI 0.72-1.05, moderate certainty evidence). The effect was unclear for hypoxic ischemic encephalopathy, umbilical prolapse, decision to birth interval in emergency cesarean section, and for severe postpartum hemorrhage. Studies with in situ multi-professional simulation-based training demonstrated the best effect.

CONCLUSIONS

Emerging evidence suggests an effect of obstetric team training on obstetric outcomes, but conflicting results call for controlled trials targeted to identify the optimal methodology for effective team training.

Does simulation improve clinical performance in management of postpartum hemorrhage?

BACKGROUND

Although simulation is now widely used to improve teamwork and communication, data demonstrating improvement in clinical outcomes are limited.

OBJECTIVE

This study aimed to examine the clinical performance and outcomes associated with postpartum hemorrhage because of uterine atony following the implementation of a multidisciplinary simulation program.

STUDY DESIGN

This was a prospective observational study of response to postpartum hemorrhage because of uterine atony in an academic medical center before (epoch 1: July 2017-June 2018) and after (epoch 2: July 2019-June 2020) implementing a multidisciplinary simulation program. A total of 22 postpartum hemorrhage simulations were performed from July 2018 to June 2019 involving more than 300 nursing, obstetrical, and anesthesia providers. The simulation program focused on managing postpartum hemorrhage events and improving teamwork and communication of the multidisciplinary teams. To evaluate the clinical effectiveness of the simulation program, the primary outcome was response to postpartum hemorrhage defined as the time from the administration of uterotonic medications to transfusion of the first unit of blood in the first 12 hours following delivery, comparing epoch 2 to epoch 1 following the implementation of a simulation program. Statistical analysis included the use of the Pearson chi-square test, Wilcoxon rank-sum test, Hodges-Lehmann statistic for differences, and bootstrap methods with a P value of <.05 considered significant.

RESULTS

Between July 1, 2017, and June 30, 2018, there were 12,305 patients who delivered, of which 495 patients (4%) required transfusion. Between July 1, 2019, and June 30, 2020, there were 12,414 patients who delivered, of which 480 patients (4%) required transfusion. When isolating cases of postpartum hemorrhage because of uterine atony in both transfused groups, there were 157 women in the presimulation group (epoch 1) and 165 women in the postsimulation group (epoch 2), respectively. There was no difference in age, race, parity, or perinatal outcomes between the 2 epochs. Women in epoch 2 began receiving blood products significantly earlier in the first 12 hours following delivery compared with women in epoch 1 (51 [range, 28-125] minutes vs 102 [range, 32-320] minutes; P=.005). In addition, there was a significantly decreased variation in the time from the administration of uterotonic medications to transfusion of blood in epoch 2 (P=.035). Furthermore, women in epoch 2 had significantly lower estimated blood loss than women in epoch 1 (1250 [range, 1000-1750] mL vs 1500 [range, 1000-2000] mL; P=.032).

CONCLUSION

The implementation of a multidisciplinary simulation program at a large academic center focusing on the management of postpartum hemorrhage was associated with an improved clinical response. Specifically, there were significantly faster times from the administration of uterotonic medications to transfusion of blood, decreased variance in the time from the administration of uterotonic medications to transfusion of blood, and lower estimated blood loss following the implementation of a simulation program. Because delay in treatment is a major cause of preventable maternal death in obstetrical hemorrhage, the results in our study provided clinical evidence that a simulation program may improve patient outcomes in such emergencies.

Using simulation team training with human's factors components in obstetrics to improve patient outcome: A review of the literature

OBJECTIVE

to assess the evidence from multidisciplinary simulation team training in obstetrics that integrates human's factors components on patient outcome.

INTRODUCTION

It has been stated that simulation-based education has the potential to improve technical and nontechnical skills. Reports from enquiries into maternal and newborn adverse outcomes, highlight that the majority of incidents are due to a breakdown of communication and a lack of crisis resource management skills (CRM). It is therefore reasonable to think that a better training on teamwork based on simulation will ultimately improve obstetrics care. In order to explore further that idea, we conducted a literature review on patient outcome after a multidisciplinary simulation training in obstetrics.

METHOD

Pubmed, Advances in health sciences education, BMC in medical education, BMC in pregnancy and Childbirth, BMJ open, BMJ Simulation and technology enhanced learning were searched from inception to May 2020 for full-text publications in English on interprofessional, multidisciplinary, obstetrics, simulation training, non-technical skills, CRM. Searches were limited to studies with a report on patient outcome after a multidisciplinary simulation program that included elements of CRM.

RESULT

Out of the ten studies selected in our review, five were single site before and after prospective studies and five were cluster before and after randomized trials. All the single site studies reported a positive outcome in low and high resource countries. Three single site studies reported a reduction between 41 and 50 % of blood transfusion after simulation team training. Two single studies reported a reduction of maternal mortality by 34 % and a decrease in an adverse obstetrics index outcome from 0.052 to 0.048 with a p-value of 0.05. Cluster studies showed either no change or some improvement in patient outcomes such as a 37 % improvement on weighted obstetrics adverse outcome, a 17 % reduction in the incidence of PPH and a 47 % reduction in the incidence of retained placenta. Stillbirths rate was reduced by 34 % while newborn deaths was down by 62 %. There was also a 15 % reduction of maternal mortality in favor of the trained team after adjustment to the secular mortality trend. Neonatal death from 24 weeks during the first 24 h was also reduced by 83 % in the intervention site compare with an increase by 18 % in the control site.

CONCLUSION

There is evidence that simulation team training that includes CRM is associated with better patient outcome. In order to consolidate this finding, appropriate methodology should be used in future studies with the support of health authorities.

Multi-professional simulation-based team training in obstetric emergencies for improving patient outcomes and trainees' performance

BACKGROUND

Simulation-based obstetric team training focuses on building a system that will anticipate errors, improve patient outcomes and the performance of clinical care teams. Simulation-based obstetric team training has been proposed as a tool to improve the overall outcome of obstetric health care.

OBJECTIVES

To assess the effects of simulation-based obstetric team training on patient outcomes, performance of obstetric care teams in practice and educational settings, and trainees' experience.

SEARCH METHODS

The Cochrane Pregnancy and Childbirth Group's Trials Register, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) were searched (14 April 2020), together with references checking and hand searching the available proceedings of 2 international conferences.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) (including cluster-randomised trials) comparing simulation-based obstetric team training with no, or other type of training.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane, to identify articles, assess methodological quality and extract data. Data from three cluster-randomised trials could be used to perform generic inverse variance meta-analyses. The meta-analyses were based on risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals (CIs). We used the GRADE approach to rate the certainty of the evidence. We used Kirkpatrick's model of training evaluation to categorise the outcomes of interest; we chose Level 3 (behavioural change) and Level 4 (patient outcome) to categorise the primary outcomes.

MAIN RESULTS

We included eight RCTs, six of which were cluster-randomised trials, involving more than 1000 training participants and more than 200,000 pregnancies/births. Four studies reported on outcome measures on Kirkpatrick level 4 (patient outcome), three studies on Kirkpatrick level 3 (performance in practice), two studies on Kitkpatrick level 2 (performance in educational settings), and none on Kirkpatrick level 1 (trainees' experience). The included studies were from Mexico, the Netherlands, the UK and the USA, all middle- and high-income countries. Kirkpatrick level 4 (patient outcome) Simulation-based obstetric team training may make little or no difference for composite outcomes of maternal and/or perinatal adverse events compared with no training (3 studies; n = 28,731, low-certainty evidence, data not pooled due to different composite outcome definitions). We are uncertain whether simulation-based obstetric team training affects maternal mortality compared with no training (2 studies; 79,246 women; very low-certainty evidence). However, it may reduce neonatal mortality (RR 0.70, 95% CI 0.48 to 1.01; 2 studies, 79,246 pregnancies/births, low-certainty evidence). Simulation-based obstetric team training may have little to no effect on low Apgar score compared with no training (RR 0.99, 95% 0.85 to 1.15; 2 studies; 115,171 infants; low-certainty evidence), but it probably reduces trauma after shoulder dystocia (RR 0.50, 95% CI 0.25 to 0.99; 1 study; moderate-certainty evidence) and probably slightly reduces the number of caesarean deliveries (RR 0.79, 95% CI 0.67 to 0.93; 1 study; n = 50,589; moderate-certainty evidence) Kirkpatrick level 3 (performance in practice) We found that simulation-based obstetric team training probably improves the performance of the obstetric teams in practice, compared with no training (3 studies; 2398 obstetric staff members, moderate-certainty evidence, data not pooled due to different outcome definitions).

AUTHORS' CONCLUSIONS

Simulation-based obstetric team training may help to improve team performance of obstetric teams, and it might contribute to improvement of specific maternal and perinatal outcomes, compared with no training. However, high-certainty evidence is lacking due to serious risk of bias and imprecision, and the effect cannot be generalised for all outcomes. Future studies investigating simulation-based obstetric team training compared to training courses with a different instructional design should carefully consider how and when to measure outcomes. Particular attention should be paid to effect measurement at the level of patient outcome, taking into consideration the low incidence of adverse maternal and perinatal events.

Simulation for intrapartum care: from training to novel device innovation

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.

"We do what we can do to save a woman" health workers' perceptions of health facility readiness for management of postpartum haemorrhage

Background: In many low-resource settings, in-service training is a common strategy to improve the performance of health workers and ultimately reduce the persistent burden of maternal mortality and morbidities. An evaluation of the Helping Mothers Survive Bleeding After Birth (HMS BAB) training as a single-component intervention in Tanzania found some positive albeit limited effect on clinical management and reduction of postpartum haemorrhage (PPH).

Aim: In order to better understand these findings, and particularly the contribution of contextual factors on the observed effects, we explored health workers’ perceptions of their health facilities’ readiness to provide PPH care.

Methods: We conducted 7 focus group discussions (FGDs) and 12 in-depth interviews (IDIs) in purposively selected intervention districts in the HMS BAB trial. FGDs and IDIs were audio-recorded, transcribed and translated verbatim. Thematic analysis, using both inductive and deductive approaches, was applied with the help of MAXQDA software.

Results: Health workers perceive that their facilities have a low readiness to provide PPH care, leading to stressful situations and suboptimal clinical management. They describe inconsistencies in essential supplies, fluctuating availability of blood for transfusion, and ineffective referral system. In addition, there are challenges in collaboration, communication and leadership support, which is perceived to prevent effective management of cases within the facility as well as in referral situations. Health workers strive to provide life-saving care to women with PPH despite the perceived challenges. In some health facilities, health workers perceive supportive clinical leadership as motivating in providing good care.

Conclusion: The potential positive effects of single-component interventions such as HMS BAB training on clinical outcome may be constraint by poor health facility readiness, including communication, leadership and referral processes that need to be addressed.

Study protocol training for life: a stepped wedge cluster randomized trial about emergency obstetric simulation-based training in a low-income country

BACKGROUND

Globally perinatal and maternal mortality rates remain unacceptably high. There is increasing evidence that simulation-based training in obstetric emergencies is associated with improvement in clinical outcomes. However, the results are not entirely consistent. The need for continued research in a wide variety of clinical settings to establish what works, where and why was recommended. The aim of this study is to investigate the effectiveness of an emergency obstetric simulation-based training program with medical technical and teamwork skills on maternal and perinatal mortality in a low-income country.

METHODS

A stepped wedge cluster randomized trial will be conducted at the medium to high-risk labour ward at Mulago Hospital, Kampala, Uganda, with an annual delivery rate of over 23,000. The training will be performed using a train-the-trainers model in which training is cascaded down from master trainers to local facilitators (gynaecologists) to learners (senior house officers). Local facilitators will be trained during a four-day train-the-trainers course with an annual repetition. The senior house officers will be naturally divided in seven clusters and randomized for the moment of training. The training consists of a one-day, monodisciplinary, simulation-based training followed by repetition training sessions. Scenarios are based on the main local causes of maternal and neonatal mortality and focus on both medical technical and crew resource management skills. Kirkpatrick's classification will be used to evaluate the training program. Primary outcome will be the composite of maternal and neonatal mortality ratios. Secondary outcome will comprise course perception, evaluation of the instructional design of the training, knowledge, technical skills, team performance, percentage of ventouse deliveries, percentage of caesarean sections, and a Weighted Adverse Outcome Score.

DISCUSSION

This stepped wedge cluster randomized trial will investigate the effect of a monodisciplinary simulation-based obstetric training in a low-income country, focusing on both medical technical skills and crew resource management skills, on patient outcome at one of the largest labour wards worldwide. We will use a robust study design which will allow us to better understand the training effects, and difficulties in evaluating training programs in low-income countries.

Simulation of an impacted fetal head extraction during cesarean section: description of the creation and evaluation of a new training program

Background Although cesarean sections at full dilatation are increasing, training in delivering a deeply impacted fetal head is lacking among obstetricians. The purpose of the study was to implement and evaluate a theoretical and simulation-based training program for this obstetrical emergency. Methods We developed a training program consisting of a theoretical introduction presenting a clinical algorithm, developed on the basis of the available literature, followed by a simulation session. We used the Kirkpatrick's framework to evaluate the program. A questionnaire was distributed, directly before, immediately and 6 weeks after the training. Self-perceived competencies were evaluated on a 6-point Likert scale. Pre- and post-test differences in the Likert scale were measured with the Wilcoxon signed rank test. Additionally, the training sessions were video recorded and rated with a checklist in relation to how well the algorithm was followed. Results Eleven residents and eight senior physicians took part to the training. More than 40% of participants experienced a comparable situation after the course during clinical work. Their knowledge and self-perceived competencies improved immediately after the training program and 6 weeks later. Major improvements were seen in the awareness of the algorithm and in the confidence in performing the reverse breech extraction (14.3% of the participants felt confident with the maneuver in the pre-training assessment compared with 66.7% 6 week post-training). Conclusion Our theoretical and simulation-based training program was successful in improving knowledge and confidence of the participants in delivering a deeply impacted fetal head during a cesarean section performed at full dilation.

Maternal Quality Outcomes and Cost

The quality of maternal care in the United States is receiving increased attention due to rising rates of severe maternal morbidity and maternal mortality when compared with other developed countries. Many of these events are considered preventable. The lack of adoption of evidence-based maternal patient safety bundles and tool kits requires immediate attention. Maternal levels of care described by the American Congress of Obstetricians and Gynecologists requires increased focus so that women are in the appropriate facility to receive care. Perinatal care management, integrated behavioral health, and preconception care should be considered a preferred methodology to achieve optimal maternal outcomes.

Effects of an in situ instructional design based postpartum hemorrhage simulation training on patient outcomes: an uncontrolled before-and-after study

Objective: To compare postpartum hemorrhage (PPH) patient outcomes before and after an in situ instructional design based PPH simulation attended by obstetrics and gynecology (OBGYN) residents.Methods: This uncontrolled before-and-after study was conducted in Recife, Brazil including all 1388 women delivering from June to August 2012 and all 1357 delivering from June to August 2013. The 36 OBGYN residents were divided into13 teams of two or three participants and were trained through ID based PPH simulation training with the following eight steps: (1) prior knowledge activation, (2) video demonstration, (3) dual-coding PPH protocol discussion-an image association during the training, (4) training scenario # 1, (5) debriefing, (6) training scenario # 2 with immediate feedback, (7) training scenario # 3, and (8) debriefing with self-assessment. The training scenarios had an increasing level of complexity. The main goal of the training was the adequate management of PPH and situational awareness improvement-the ability to anticipate, recognize, and intercept unfolding error chains. The primary patient outcomes rates used for the before and after comparison were therapeutic uterotonics use within 24 h of birth and blood transfusion. Secondary outcomes were therapeutic oxytocin mean dosage IU within 24 h of birth, postpartum Hb < 6 g/dL, among others. Chi-square test was used for categorical variables comparison and independent t-test for continuous variables.Results: PPH rates were 100 (7.2% of 2012 deliveries) and 80 cases (5.9% of 2013 deliveries), respectively. Comparison of primary post- and pre-simulation outcomes revealed no significant differences. However, in the comparison for therapeutic oxytocin mean dosage IU within 24 h of birth, there was an increase found after the simulation (15.98 ± 7.4 versus 25.1 ± 12.3; p < .001). For all other outcome measures, there were no statistical differences.Conclusions: In situ ID based PPH simulation leads to an increase in the mean dosage of oxytocin after training, in selected cases. This may indicate better situational awareness when managing women with PPH.

In-situ Interprofessional Perinatal Drills: The Impact of a Structured Debrief on Maximizing Training While Sensing Patient Safety Threats

Introduction In-situ interprofessional emergency team training improves participants' with confidence and knowledge and identifies latent safety threats. This study examined the impact of a structured debrief on an interprofessional perinatal team's ability to identify latent safety threats and assess competency in managing perinatal emergencies. It was hypothesized that latent safety threats would be reduced and checklist compliance would increase during subsequent in-situ perinatal team training. Methods Two in-situ training sessions were held six months apart. The perinatal emergency response team provided care for a standardized patient with preterm twin gestation. Each session included off-ward delivery and resuscitation of the first infant, transportation to appropriate inpatient units, cesarean delivery, and resuscitation of the second twin. Postpartum hemorrhage ensued, requiring massive transfusion protocol activation. Medical experts assessed team performance with critical action checklists. A structured debrief identified latent safety threats, developed action plans, and reviewed checklist compliance. Checklist compliance rates were analyzed using a z-ratio test. Results The first training session: seven teams (75 staff) completed 75% (292/391) critical action checklist items and identified 34 latent safety threats. Second training session: four teams (45 staff) completed 89% (94/106) critical action checklist items. Ten latent safety threats were mitigated during the second session. Utilizing a z-ratio, a significant difference was detected between the overall checklist compliance rates of the two sessions, z = -3.069, p = .002. Post-hoc power calculation was <10%. Conclusions In-situ interprofessional perinatal emergency team training is feasible, identifies latent patient safety threats, and may improve team competency.

Improved clinical management but not patient outcome in women with postpartum haemorrhage-An observational study of practical obstetric team training

Objective

Postpartum haemorrhage (PPH) is the most common obstetric emergency. A well-established postpartum haemorrhage protocol in the labour ward is crucial for effective treatment. The aim of the study was to investigate if practical obstetric team training improves the patient outcome and clinical management of PPH.

Setting

The practical obstetric team training (PROBE) at Linköping University Hospital, Sweden, with approximate 3000 deliveries annually, was studied between the years of 2004–2011. Each team consisted of one or two midwives, one obstetrician or one junior doctor and one nurse assistant. Emergency obstetrics cases were trained in a simulation setting. PROBE was scheduled during work hours at an interval of 1.5 years.

Population

Pre-PROBE women (N = 419 were defined as all women with vaginal birth between the years of 2004–2007 with an estimated blood loss of ≥1000 ml within the first 24 hours of delivery. Post-PROBE women (N = 483) were defined as all women with vaginal birth between the years of 2008–2011 with an estimated blood loss of ≥1000 ml within the first 24 hours of delivery. The two groups were compared regarding blood loss parameters and management variables using retrospective data from medical records.

Results

No difference was observed in estimated blood loss, haemoglobin level, blood transfusions or the incidence of postpartum haemorrhage between the two groups. Post-PROBE women had more often secured venous access (p<0.001), monitoring of vital signs (p<0.001) and received fluid resuscitation (p<0.001) compared to pre-PROBE women. The use of uterine massage was also more common among the post-PROBE women compared with the pre-PROBE women (p<0.001).

Conclusion

PROBE improved clinical management but not patient outcome in women with postpartum haemorrhage in the labour ward. These new findings may have clinical implications since they confirm that training was effective concerning the management of postpartum haemorrhage. However, there is still no clear evidence that simulation training improve patient outcome in women with PPH.

Maternal Obstetric Complication Rates Remain High in Illinois: A Retrospective Study, 2010-2015

BACKGROUND

Quality measures for maternal childbirth outcomes remain controversial, although there is a consensus that maternal morbidity has been increasing in recent years. To determine whether childbirth safety has declined in Illinois, the likelihood of maternal obstetric complications was modeled by using both an established measure of severe maternal morbidity and a more expansive complication coding algorithm.

METHODS

In a retrospective cohort study of 792,122 deliveries at 127 Illinois hospitals from July 2010 to September 2015, International Classification of Diseases, Ninth Revision (ICD-9) codes were used to identify Centers for Disease Control and Prevention-defined severe maternal morbidity, as well as other maternal complications defined by a route of delivery-specific algorithm originally used to evaluate the quality of obstetrics residency programs. Poisson and logistic regression were used to analyze the likelihood of delivery complications during the study period, controlling for maternal sociodemographic and clinical characteristics.

RESULTS

The severe maternal morbidity rate was 0.99% for vaginal and 3.76% for cesarean deliveries. The maternal complication rates were much higher-9.44% for vaginal and 14.66% for cesarean deliveries. After controlling for patient characteristics, severe maternal morbidity remained constant, but there was a statistically significant, approximately 20% increase in the incidence of other maternal complications from 2010 to 2015 for both vaginal and cesarean deliveries.

CONCLUSION

Severe maternal morbidity remained stable during the study period, but other maternal complications increased significantly. Severe maternal morbidity may undercount potentially preventable complications. New, more reliable measures of preventable delivery complications may have to be based on electronic health record standards.

Impact of multi-professional, scenario-based training on postpartum hemorrhage in Tanzania: a quasi-experimental, pre- vs. post-intervention study

BACKGROUND

Tanzania has a relatively high maternal mortality ratio of 410 per 100,000 live births. Severe postpartum hemorrhage (PPH) is a major cause of maternal deaths, but in most cases, it is preventable. However, most pregnant women that develop PPH, have no known risk factors. Therefore, preventive measures must be offered to all pregnant women. This study investigated the effects of multi-professional, scenario-based training on the prevention and management of PPH at a Tanzanian zonal consultant hospital. We hypothesized that scenario-based training could contribute to improved competence on PPH-management, which would result in improved team efficiency and patient outcome.

METHODS

This quasi-experimental, pre-vs. post-interventional study involved on-site multi-professional, scenario-based PPH training, conducted in a two-week period in October 2013 and another 2 weeks in November 2014. Training teams included nurses, midwives, doctors, and medical attendants in the Department of Obstetrics and Gynecology. After technical skill training on the birthing simulator MamaNatalie®, the teams practiced in realistic scenarios on PPH. Each scenario was followed by debriefing and repeated scenario. Afterwards, the group swapped roles and the observers became the participants. To evaluate the effects of training, we measured patient outcomes by determining blood transfusion rates. Patient data were collected by randomly sampling Medical birth registry files from the pre-training and post-training study periods (n = 1667 and 1641 files, respectively). Data were analyzed with the Chi-square test, Mann-Whitney U-test, and binary logistic regression.

RESULTS

The random patient samples (n = 3308) showed that, compared to pre-training, post-training patients had a 47% drop in whole blood transfusion rates and significant increases in cesarean section rates, birth weights, and vacuum deliveries. The logistic regression analysis showed that transfusion rates were significantly associated with the time period (pre- vs. post-training), cesarean section, patients tranferred from other hospitals, maternal age, and female genital mutilation and cutting.

CONCLUSIONS

We found that multi-professional, scenario-based training was associated with a significant, 47% reduction in whole blood transfusion rates. These results suggested that training that included all levels of maternity staff, repeated sessions with realistic scenarios, and debriefing may have contributed to reduced blood transfusion rates in this high-risk maternity setting.

Simulation-based team training for multi-professional obstetric care teams to improve patient outcome: a multicentre, cluster randomised controlled trial

OBJECTIVE

To investigate whether simulation-based obstetric team training in a simulation centre improves patient outcome.

DESIGN

Multicentre, open, cluster randomised controlled trial.

SETTING

Obstetric units in the Netherlands.

POPULATION

Women with a singleton pregnancy beyond 24 weeks of gestation.

METHODS

Random allocation of obstetric units to a 1-day, multi-professional, simulation-based team training focusing on crew resource management (CRM) in a simulation centre or to no such team training. Intention-to-treat analyses were performed at the cluster level, including a measurement 1 year prior to the intervention.

MAIN OUTCOME MEASURES

Primary outcome was a composite outcome of obstetric complications during the first year post-intervention, including low Apgar score, severe postpartum haemorrhage, trauma due to shoulder dystocia, eclampsia and hypoxic-ischaemic encephalopathy. Maternal and perinatal mortality were also registered.

RESULTS

Each study group included 12 units with a median unit size of 1224 women, combining for a total of 28 657 women. In total, 471 medical professionals received the training course. The composite outcome of obstetric complications did not differ between study groups [odds ratio (OR) 1.0, 95% confidence interval (CI) 0.80-1.3]. Team training reduced trauma due to shoulder dystocia (OR 0.50, 95% CI 0.25-0.99) and increased invasive treatment for severe postpartum haemorrhage (OR 2.2, 95% CI 1.2-3.9) compared with no intervention. Other outcomes did not differ between study groups.

CONCLUSION

A 1-day, off-site, simulation-based team training, focusing on teamwork skills, did not reduce a composite of obstetric complications.

TWEETABLE ABSTRACT

1-day, off-site, simulation-based team training did not reduce a composite of obstetric complications.
