Simulation-Based Training in Emergency Obstetric Care in Sub-Saharan and Central Africa: A Scoping Review

Background

Every day approximately 810 women die from complications related to pregnancy and childbirth worldwide. Around two thirds of these deaths happen in sub-Saharan Africa. One of the strategies to decrease these numbers is improving the quality of care by emergency obstetric simulation-based training. The effectiveness of such training programs depends on the program's instructional design.

Objective

This review gives an overview of studies about emergency obstetric simulation-based training and examines the applied instructional design of the training programs in sub-Saharan and Central Africa.

Methods

We searched Medline, Embase and Cochrane Library from inception to May 2021. Peer-reviewed articles on emergency obstetric, postgraduate, simulation-based training in sub-Saharan and Central Africa were included. Outcome measures were categorized based on Kirkpatrick's levels of training evaluation. The instructional design was evaluated by using the ID-SIM questionnaire.

Findings

In total, 47 studies met the inclusion criteria. Evaluation on Kirkpatrick level 1 showed positive reactions in 18 studies. Challenges and recommendations were considered. Results on knowledge, skills, and predictors for these results (Kirkpatrick level 2) were described in 29 studies. Retention as well as decay of knowledge and skills over time were presented. Results at Kirkpatrick level 3 were measured in 12 studies of which seven studies demonstrated improvements of skills on-the-job. Improvements of maternal and neonatal outcomes were described in fifteen studies and three studies reported on cost-estimations for training rollout (Kirkpatrick level 4). Instructional design items were heterogeneously applied and described.

Conclusions

Results of 47 studies indicate evidence that simulation-based training in sub-Saharan and Central Africa can have a positive impact across all four levels of Kirkpatrick's training evaluation model. However, results were not consistent across all studies and the effects vary over time. A detailed description of instructional design features in future publications on simulation-based training will contribute to a deeper understanding of the underlying mechanisms that determine why certain training programs are more effective in improving maternal and neonatal healthcare outcomes than other.

The effect of blister packaging Iron and Folate on adherence to medication and hemoglobin levels among pregnant women at National Referral Hospital antenatal clinics in a low to middle income country: a Randomised Controlled Trial (The IFAd Trial)

Introduction

Anemia in pregnancy is an important global public health problem. It is estimated that 38% of pregnant women worldwide are anemic. In Africa, literature from observational studies show 20% of maternal deaths are attributed to anemia. In Uganda, 50% of pregnant women have iron deficiency anaemia. The proportion of pregnant women receiving Iron-Folic acid (IFA) supplementation has improved. However, the number of IFA pills consumed is still low. We carried out a randomized controlled trial to determine the effect of dispensing blister and loose packaged IFA pills on adherence measured by count on next return visit and hemoglobin levels among pregnant women at two National Referral Hospitals in Kampala, Uganda.

Methods

This trial was conducted between April and October 2016. Nine hundred fifty pregnant women at ≤28 weeks were randomized to either the blister (intervention arm) or loose (control arm) packaged IFA. The participants completed the baseline measurements and received 30 pills of IFA at enrolment to swallow one pill per day. We assessed adherence by pill count and measured hemoglobin at four and 8 weeks. The results were presented using both intention-to-treat and per-protocol analysis.

Results

There were 474 participants in the control and 478 in the intervention arms. Adherence to IFA intake was similar in the two groups at 4th week (40.6 and 39.0%, p = 0.624) and 8th week (51.9 and 46.8%, p = 0.119). The mean hemoglobin level at 4 weeks was higher in the blister than in the loose packaging arms (11.9 + 1.1 g/dl and 11.8 + 1.3 g/dl, respectively; p = 0.02), however, similar at week 8 (12.1 + 1.2 and 12.0 + 1.3, respectively; p = 0.23). However, over the 8-week period blister packaging arm had a higher change in hemoglobin level compared to loose package (blister package 0.6 ± 1.0; loose packaging 0.2 ± 1.1; difference: 0.4 g/dL (95% CI: 0.24–0.51 g/dL); p = 0.001. There were no serious adverse events.

Conclusions

Our results showed no effect of blister packaging on IFA adherence among pregnant women. However, our findings showed that blister packaged group had a higher hemoglobin increase compared to loose iron group.

Evaluating the Instructional Design and Effect on Knowledge, Teamwork, and Skills of Technology-Enhanced Simulation-Based Training in Obstetrics in Uganda: Stepped-Wedge Cluster Randomized Trial

BACKGROUND

Simulation-based training is a common strategy for improving the quality of facility-based maternity services and is often evaluated using Kirkpatrick's theoretical model. The results on the Kirkpatrick levels are closely related to the quality of the instructional design of a training program. The instructional design is generally defined as the "set of prescriptions for teaching methods to improve the quality of instruction with a goal of optimizing learning outcomes."

OBJECTIVE

The aim of this study is to evaluate the instructional design of a technology-enhanced simulation-based training in obstetrics, the reaction of participants, and the effect on knowledge, teamwork, and skills in a low-income country.

METHODS

A stepped-wedge cluster randomized trial was performed in a university hospital in Kampala, Uganda, with an annual delivery volume of over 31,000. In November 2014, a medical simulation center was installed with a full-body birthing simulator (Noelle S550, Gaumard Scientific), an interactive neonate (Simon S102 Newborn CPR Simulator, Gaumard Scientific), and an audio and video recording system. Twelve local obstetricians were trained and certified as medical simulation trainers. From 2014 to 2016, training was provided to 57 residents in groups of 6 to 9 students. Descriptive statistics were calculated for ten instructional design features of the training course measured by the 42-item ID-SIM (Instructional Design of a Simulation Improved by Monitoring). The Wilcoxon signed rank test was conducted to investigate the differences in scores on knowledge, the Clinical Teamwork Scale, and medical technical skills.

RESULTS

The mean scores on the ten instructional design features ranged from 54.9 (95% CI 48.5-61.3) to 84.3 (95% CI 80.9-87.6) out of 100. The highest mean score was given on the feature feedback and the lowest scores on repetitive practice and controlled environment. The overall score for the training day was 92.8 out of 100 (95% CI 89.5-96.1). Knowledge improved significantly, with a test score of 63.4% (95% CI 60.7-66.1) before and 78.9% (95% CI 76.8-81.1) after the training (P<.001). The overall score on the 10-point Clinical Teamwork Scale was 6.0 (95% CI 4.4-7.6) before and 5.9 (95% CI 4.5-7.2) after the training (P=.78). Medical technical skills were scored at 55.5% (95% CI 47.2-63.8) before and 65.6% (95% CI 56.5-74.7) after training (P=.08).

CONCLUSIONS

Most instructional design features of a technology-enhanced simulation-based training in obstetrics in a low-income country were scored high, although intervals were large. The overall score for the training day was high, and knowledge did improve after the training program, but no changes in teamwork and (most) medical technical skills were found. The lowest-scored instructional design features may be improved to achieve further learning aims.

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.

Prevalence of hepatitis B virus infection and associated risk factors among pregnant women attending antenatal clinic in Mulago Hospital, Uganda: a cross-sectional study

AIM

To determine the prevalence and factors associated with hepatitis B virus infection among pregnant women attending antenatal clinic in Mulago Hospital.

DESIGN

Cross-sectional observational study.

SETTING

Mulago National Referral Hospital, Uganda, antenatal clinic.

PARTICIPANTS

We randomly selected 340 pregnant women attending their first antenatal visit at Mulago Hospital antenatal clinic.

PRIMARY OUTCOME

Hepatitis B surface antigen positivity.

RESULTS

We recruited 340 participants, with a mean age of 27±5.7 years, and a median gravidity of 3. The prevalence of hepatitis B virus infection among pregnant women attending the antenatal clinic in Mulago Hospital, in our study, was 2.9% (95% CI 1.58% to 5.40%, n=10). Factors positively associated with hepatitis B virus infection were: marital status (adjusted OR (aOR)=11.37, p=0.002), having a hepatitis B positive family member (aOR=49.52, p<0.001) and having had a blood or body fluid splash to mucous membranes from a hepatitis B positive patient (aOR=61.69, p=0.015). Other factors such as age, socioeconomic status, number of sexual partners, HIV serostatus, piercing of ears and history of blood transfusion were not significantly associated with hepatitis B virus infection in this study.

CONCLUSION

The prevalence of hepatitis B virus infection among pregnant women attending antenatal clinic in Mulago Hospital was of intermediate endemicity. We found that marital status, having a hepatitis B positive family member at home and having had a blood or body fluid splash to mucous membranes from a hepatitis B positive patient were independently associated with hepatitis B infection. Factors such as age, HIV status, history of blood transfusion, piercing of ears and social status were not associated with hepatitis B status in this study.

Maternal, reproductive and obstetric factors associated with preterm births in Mulago Hospital, Kampala, Uganda: a case control study

Introduction

Preterm birth, a leading cause of neonatal mortality accounts for 35 percent of all neonatal deaths worldwide. Uganda's high preterm birth rate of 13.6 per 1000 live births ranks 28^th in the world. Efforts at reducing these pre-term births must entail interventions that target any associated risk factors. This study therefore aimed at identifying and describing the risk factors for preterm births among mothers delivering in Mulago Hospital.

Methods

This was a case control study among postpartum women in Mulago Hospital. Ninety nine women with preterm newborns were recruited as cases and 193 with full term babies were the controls. A semi-structured questionnaire was used to collect data. Data was entered into Epidata version 3.1 and exported to STATA 11 for univariate analysis and multivariate analysis by logistic regression.

Results

Risk factors for preterm birth included maternal height less than 1.5 meters (OR 131.08 (20.35-844.02)), rural residence (OR 6.56(2.68-16.10)) and failure to attend antenatal care clinic (OR 8.88(1.44-54.67)). Pregnancy related risk factors included PPROM (OR 287.11(49.26-1673.28)), antepartum haemorrhage (OR 7.33(1.23-43.72)) and preeclampsia/eclampsia (OR 16.24(3.11-84.70)).

Conclusion

Preterm birth is more likely to occur in women of short stature, living in rural areas and those who do not attend antenatal care clinic. The preterm birth risk is higher for women who get PPROM, APH and preeclampsia/eclampsia in pregnancy. Early recognition and management of these high risk conditions among pregnant women may lead to a reduction in preterm birth rates.
