Frequent refresher training on newborn resuscitation and potential impact on perinatal outcome over time in a rural Tanzanian hospital: an observational study

Outcomes of a Program to Reduce Birth-Related Mortality in Tanzania

BACKGROUND

Birth-related mortality is a major contributor to the burden of deaths worldwide, especially in low-income countries. The Safer Births Bundle of Care program is a combination of interventions developed to improve the quality of care for mother and baby with the goal of reducing birth-related mortality.

METHODS

We performed a 3-year stepped-wedge cluster-randomized study of the Safer Births program at 30 high-burden facilities in five regions in Tanzania. The bundle of interventions in the program was aimed at continuous quality improvement through regular onsite simulation-based training, the collection and use of local clinical data, the assistance of trained local facilitators, and the use of innovative tools for perinatal care. The primary outcome was perinatal death, which included intrapartum stillbirth (suspected death during labor) and neonatal death within the first 24 hours after birth.

RESULTS

A total of 281,165 mothers and 277,734 babies were included in the final analysis. The estimated incidence of perinatal death decreased from 15.3 deaths per 1000 births in the baseline period of the program to 12.5 deaths per 1000 births after implementation (adjusted relative risk, 0.82; 95% confidence interval [CI], 0.73 to 0.92; P = 0.001), with substantial heterogeneity among regions. The incidence of intrapartum stillbirths was 8.6 deaths per 1000 births in the baseline period and 8.7 deaths per 1000 births after implementation (adjusted relative risk, 1.01; 95% CI, 0.87 to 1.17), and the incidence of neonatal deaths within the first 24 hours after birth was 6.4 and 3.9 deaths per 1000 births, respectively (adjusted relative risk, 0.61; 95% CI, 0.49 to 0.77). No serious adverse events were reported.

CONCLUSIONS

Implementation of the Safer Births Bundle of Care program showed the feasibility of integrating quality-improvement efforts targeting birth-related emergencies in resource-limited settings and was associated with a significant reduction in perinatal mortality.

Increase in Newborns Ventilated Within the First Minute of Life and Reduced Mortality After Clinical Data-Guided Simulation Training

INTRODUCTION

Birth asphyxia-related deaths is a major global concern. Rapid initiation of ventilation within the "Golden Minute" is important for intact survival but reported to be challenging, especially in low-/middle-income countries. Helping Babies Breathe (HBB) is a simulation-based training program for newborn resuscitation. The aim of this HBB quality improvement (QI) intervention was to decrease time from birth to ventilation and document potential changes in perinatal outcomes.

METHOD

Prospective observational QI study in a rural Tanzanian hospital, October 1, 2017, to August 31, 2021, first-year baseline, second-year QI/simulation intervention, and 2-year postintervention. Trained research assistants observed wide-ranging information from all births (N = 12,938). The intervention included monthly targeted HBB simulation training addressing documented gaps in clinical care, clinical debriefings, and feedback meetings.

RESULTS

During the QI/simulation intervention, 68.5% nonbreathing newborns were ventilated within 60 seconds after birth compared with 15.8% during baseline and 42.2% and 28.9% during the 2 postintervention years ( P < 0.001). Time to first ventilation decreased from median 101 (quartiles 72-150) to 55 (45-67) seconds ( P < 0.001), before increasing to 67 (49-97) and 85 (57-133) seconds after intervention. More nonbreathing newborns were ventilated in the intervention period (12.9%) compared with baseline (8.5%) and the postintervention years (10.6% and 9.4%) ( P < 0.001). Assumed fresh stillborns decreased significantly from baseline to intervention (3.2%-0.7%) ( P = 0.013).

CONCLUSIONS

This QI study demonstrates an increase in nonbreathing newborns being ventilated within the Golden Minute and a significant reduction in fresh stillborns after introduction of an HBB QI/simulation intervention. Improvements are partially reversed after intervention, highlighting the need for continuous simulation-based training and research into QI efforts essential for sustainable changes.

"Safer Births Bundle of Care" Implementation and Perinatal Impact at 30 Hospitals in Tanzania-Halfway Evaluation

Safer Births Bundle of Care (SBBC) consists of innovative clinical and training tools for improved labour care and newborn resuscitation, integrated with new strategies for continuous quality improvement. After implementation, we hypothesised a reduction in 24-h newborn deaths, fresh stillbirths, and maternal deaths by 50%, 20%, and 10%, respectively. This is a 3-year stepped-wedged cluster randomised implementation study, including 30 facilities within five regions in Tanzania. Data collectors at each facility enter labour and newborn care indicators, patient characteristics and outcomes. This halfway evaluation reports data from March 2021 through July 2022. In total, 138,357 deliveries were recorded; 67,690 pre- and 70,667 post-implementations of SBBC. There were steady trends of increased 24-h newborn and maternal survival in four regions after SBBC initiation. In the first region, with 13 months of implementation (n = 15,658 deliveries), an estimated additional 100 newborns and 20 women were saved. Reported fresh stillbirths seemed to fluctuate across time, and increased in three regions after the start of SBBC. Uptake of the bundle varied between regions. This SBBC halfway evaluation indicates steady reductions in 24-h newborn and maternal mortality, in line with our hypotheses, in four of five regions. Enhanced focus on uptake of the bundle and the quality improvement component is necessary to fully reach the SBBC impact potential as we move forward.

Utilization of a novel mobile application, "HBB Prompt", to reduce Helping Babies Breathe skills decay

BACKGROUND

Helping Babies Breathe (HBB) is a newborn resuscitation training program designed to reduce neonatal mortality in low- and middle-income countries. However, skills decay after initial training is a significant barrier to sustained impact.

OBJECTIVE

To test whether a mobile app, HBB Prompt, developed with user-centred design, helps improve skills and knowledge retention after HBB training.

METHODS

HBB Prompt was created during Phase 1 of this study with input from HBB facilitators and providers from Southwestern Uganda recruited from a national HBB provider registry. During Phase 2, healthcare workers (HCWs) in two community hospitals received HBB training. One hospital was randomly assigned as the intervention hospital, where trained HCWs had access to HBB Prompt, and the other served as control without HBB Prompt (NCT03577054). Participants were evaluated using the HBB 2.0 knowledge check and Objective Structured Clinical Exam, version B (OSCE B) immediately before and after training, and 6 months post-training. The primary outcome was difference in OSCE B scores immediately after training and 6 months post-training.

RESULTS

Twenty-nine HCWs were trained in HBB (17 in intervention, 12 in control). At 6 months, 10 HCW were evaluated in intervention and 7 in control. In intervention and control respectively, the median OSCE B scores were: 7 vs. 9 immediately before training, 17 vs. 21 immediately after training, and 12 vs. 13 at 6 months after training. Six months after training, the median difference in OSCE B scores was -3 (IQR -5 to -1) in intervention and -8 (IQR -11 to -6) in control (p = 0.02).

CONCLUSION

HBB Prompt, a mobile app created by user-centred design, improved retention of HBB skills at 6 months. However, skills decay remained high 6 months after training. Continued adaptation of HBB Prompt may further improve maintenance of HBB skills.

Adaptation of Essential Care for Every Baby educational program to improve infant outcomes in the context of Zika

BACKGROUND

The outbreak and ongoing transmission of Zika virus provided an opportunity to strengthen essential newborn care and early childhood development systems through collaboration with the US Agency for International Development Applying Science to Strengthen and Improve Systems (USAID ASSIST). The objective was to create a system of sustainable training dissemination which improves newborn care-related quality indicators in the context of Zika.

METHODS

From 2018-19, USAID ASSIST supported a series of technical assistance visits by the American Academy of Pediatrics (AAP) in four Caribbean countries to strengthen the clinical capacity in care of children potentially affected by Zika through dissemination of Essential Care for Every Baby (ECEB), teaching QI methodology, coaching visits, and development of clinical care guidelines. ECEB was adapted to emphasize physical exam findings related to Zika. The first series of workshops were facilitated by AAP technical advisors and the second series were facilitated by the newly trained local champions. Quality of care was monitored with performance indicators at 134 health facilities.

RESULTS

A repeated measures (pre-post) ANOVA was conducted, revealing significant pre-post knowledge gains [F(1) = 197.9, p < 0.001] on knowledge check scores. Certain performance indicators related to ECEB practices demonstrated significant changes and midline shift on the run chart in four countries.

CONCLUSION

ECEB can be adapted to incorporate important local practices, causes of neonatal morbidity and mortality, and differing healthcare system structures, which, as one part of a larger technical assistance package, leads to improved performance of health systems.

Beyond research: improved perinatal care through scale-up of a Moyo fetal heart rate monitor coupled with simulation training in northern Tanzania for helping babies breathe

BACKGROUND

The purpose of this project was to improve perinatal survival by introducing Moyo Fetal Heart Rate (FHR) Monitor coupled with neonatal resuscitation simulation training.

METHODS

The implementation was done at three district hospitals. We assessed health care workers' (HCW's) skills and perinatal death trends during implementation. Baseline data were collected from the hospitals before implementation. Newborn resuscitation (NR) skills were assessed before and after simulation training. Assessment of perinatal outcomes was done over 2 years of implementation. We used descriptive analysis; a t-test (paired and independent two-sample) and a one-way Anova test to report the findings.

RESULTS

A total of 107 HCW's were trained on FHR monitoring using Moyo and NR knowledge and skills using NeoNatalie simulators. The knowledge increased post-training by 13.6% (p <  0.001). Skills score was increased by 25.5 and 38.2% for OSCE A and B respectively (p <  0.001). The overall fresh stillbirths rate dropped from 9 to 5 deaths per 1000 total births and early neonatal deaths at 7 days from 5 to 3 (p <  0.05) deaths per 1000 live births over 2 years of implementation.

CONCLUSION

There was a significant improvement of newborn resuscitation skills among HCW's and neonatal survival at 2 years. Newborn resuscitation training coupling with Moyo FHR monitor has shown potential for improving perinatal survival. However, further evaluation is needed to explore the full potential of the package.

Neonatal Resuscitation Skill-Training Using a New Neonatal Simulator, Facilitated by Local Motivators: Two-Year Prospective Observational Study of 9000 Trainings

Globally, intrapartum-related complications account for approximately 2 million perinatal deaths annually. Adequate skills in neonatal resuscitation are required to reduce perinatal mortality. NeoNatalie Live is a newborn simulator providing immediate feedback, originally designed to accomplish Helping Babies Breathe training in low-resource settings. The objectives of this study were to describe changes in staff participation, skill-training frequency, and simulated ventilation quality before and after the introduction of “local motivators” in a rural Tanzanian hospital with 4000–5000 deliveries annually. Midwives (n = 15–27) were encouraged to perform in situ low-dose high-frequency simulation skill-training using NeoNatalie Live from September 2016 through to August 2018. Frequency and quality of trainings were automatically recorded in the simulator. The number of skill-trainings increased from 688 (12 months) to 8451 (11 months) after the introduction of local motivators in October 2017. Staff participation increased from 43% to 74% of the midwives. The quality of training performance, measured as “well done” feedback, increased from 75% to 91%. We conclude that training frequency, participation, and performance increased after introduction of dedicated motivators. In addition, the immediate constructive feedback features of the simulator may have influenced motivation and training quality performance.

Assessing the effectiveness of newborn resuscitation training and skill retention program on neonatal outcomes in Madhesh Province, Nepal

Intrapartum events leading to asphyxia at birth are among the leading causes of neonatal morbidity and mortality in Nepal. In response to this, the Nepal Ministry of Health and Population adopted Helping Babies Breathe (HBB) as a tool to improve neonatal resuscitation competencies. The effectiveness of HBB trainings has been well established. However, challenges remain in maintaining skills over time. Safa Sunaulo Nepal (SSN), with support from Latter-day Saint Charities (LDS Charities) designed an initiative for scaling up newborn resuscitation training and skills maintenance over time. This paper reports on the implementation of the SSN model of newborn resuscitation trainings and skill retention, and the changes in perinatal outcomes that occurred after the program. The program built capacity among facility-based trainers for the scale up and maintenance of resuscitation skills in 20 facilities in Madhesh Province, Nepal. A single external Mentor coached and assisted the facility-based trainers, provided general support, and monitored progress. Prospective outcome monitoring tracked changes in health metrics for a period of 14 months. Data was gathered on the neonatal health outcomes of 68,435 vaginal deliveries and 9,253 cesarean sections. Results indicate decreases in neonatal deaths under 24 hours of life (p<0.001), intrapartum stillbirths (p<0.001), and the number of sick newborns transferred from the maternity unit (p<0.001). During the program, facility-based trainers taught resuscitation skills to 231 medical personnel and supported ongoing skill retention. The SSN model for newborn resuscitation training and skills retention is a low-cost, evidence-based program focusing on facility-based trainers who are mentored and supported to scale-up and sustain resuscitation skills over time. Findings from the report are suggestive that the model had a substantial influence on critical neonatal outcomes. Future programs focused on improving neonatal outcomes may benefit by incorporating program elements of SSN model.

A Randomised Controlled Study of Low-Dose High-Frequency In-Situ Simulation Training to Improve Newborn Resuscitation

Positive pressure ventilation of the non-breathing newborn is a critical and time-sensitive intervention, considered to be the cornerstone of resuscitation. Many healthcare providers working in delivery units in high-resource settings have little opportunity to practise this skill in real life, affecting their performance when called upon to resuscitate a newborn. Low-dose, high-frequency simulation training has shown promise in low-resource settings, improving ventilation performance and changing practice in the clinical situation. We performed a randomised controlled study of low-dose, high-frequency simulation training for maintenance of ventilation competence in a multidisciplinary staff in a busy teaching hospital in Norway. We hypothesised that participants training according to a low-dose, high-frequency protocol would perform better than those training as they wished. Our results did not support this, although the majority of protocol participants were unable to achieve training targets. Subgroup analysis comparing no training to at least monthly training did identify a clear benefit to regular simulation practice. Simulated ventilation competence improved significantly for all participants over the course of the study. We conclude that frequent, short, simulation-based training can foster and maintain newborn ventilation skills in a multidisciplinary delivery unit staff in a high-resource setting.

Optimizing initial neonatal resuscitation to reduce neonatal encephalopathy around the world

One million two hundred thousand neonatal lives are lost each year due to intrapartum-related events; 99% of these deaths occur in low- and lower middle-income countries. Neonates exposed to intrapartum-related events present with failure to breathe at birth. Quick and effective delivery room management of these neonates is critical in the prevention of brain injury. Given the prominent role of lung aeration in the cardiopulmonary transition at birth, the mainstay of neonatal resuscitation is effective ventilation. Basic neonatal resuscitation focuses on simple stimulation, airway positioning and clearing, and bag-mask ventilation. Although principles for basic neonatal resuscitation remain the same for high- and low-resource settings, guidelines may differ based on available human and material resources. Formal training in basic resuscitation reduces intrapartum-related neonatal mortality in low-resource settings. However, there remain opportunities to improve provider performance for increased impact with other strategies such as regular practice and continuous quality improvement.

The impact of introducing ambulance and delivery fees in a rural hospital in Tanzania

Background

Access to health care facilities is a key requirement to enhance safety for mothers and newborns during labour and delivery. Haydom Lutheran Hospital (HLH) is a regional hospital in rural Tanzania with a catchment area of about two million inhabitants. Up to June 2013 ambulance transport and delivery at HLH were free of charge, while a user fee for both services was introduced from January 2014. We aimed to explore the impact of introducing user fees on the population of women giving birth at HLH in order to document potentially unwanted consequences in the period after introduction of fees.

Methods

Retrospective analysis of data from a prospective observational study. Data was compared between the period before introduction of fees from February 2010 through June 2013 and the period after from January 2014 through January 2017. Logistic regression modelling was used to construct risk-adjusted variable-life adjusted display (VLAD) and cumulative sum (CUSUM) plots to monitor changes.

Results

A total of 28,601 births were observed. The monthly number of births was reduced by 17.3% during the post-introduction period. Spontaneous vaginal deliveries were registered less frequently with a decrease of about 17/1000 births in non-cephalic presentations. Labour complications and caesarean sections increased with about 80/1000 births. There was a reduction in newborns with birth weight less than 2500 g. The observed changes were stable over time. For most variables, a significant change could be detected after a few weeks.

Conclusion

After the introduction of ambulance and delivery fees, an increase in labour complications and caesarean sections and a decrease in newborns with low birthweight were observed. This might indicate that women delay the decision to seek skilled birth attendance or do not seek help at all, possibly due to financial reasons. Lower rates of births in a safe health care facility like HLH is of great concern, as access to skilled birth attendance is a key requirement in order to further reduce perinatal mortality. Therefore, free delivery care should be a high priority.

Increased perinatal survival and improved ventilation skills over a five-year period: An observational study

Background and aim

The Helping Babies Breathe program gave major reductions in perinatal mortality in Tanzania from 2009 to 2012. We aimed to study whether this effect was sustained, and whether resuscitation skills changed with continued frequent training.

Methods

We analysed prospective data covering all births (n = 19,571) at Haydom Lutheran Hospital in Tanzania from July 2013 –June 2018. Resuscitation training was continued during this period. All deliveries were monitored by an observer recording the timing of events and resuscitation interventions. Heart rate was recorded by dry-electrode ECG and bag-mask-ventilation by sensors attached to the resuscitator device. We analyzed changes over time in outcomes, use of resuscitation interventions and performance of resuscitation using binary regression models with the log-link function to obtain adjusted relative risks.

Results

With introduction of user fees for deliveries since 2014, the number of deliveries decreased by 30% from start to the end of the five-year period. An increase in low heart rate at birth and need for bag-mask-ventilation indicate a gradual selection of more vulnerable newborns delivered in the hospital over time.

Despite this selection, newborn deaths <24 hours did not change significantly and was maintained at an average of 8.8/1000 live births. The annual reductions in relative risk for perinatal death adjusted for vulnerability factors was 0.84 (95%CI 0.76–0.94).

During the five-year period, longer duration of bag-mask ventilation sequences without interruption was observed. Delivered tidal volumes were increased and mask leak was decreased during ventilation. The time to initiation or total duration of ventilation did not change significantly.

Conclusion

The reduction in 24-hour newborn mortality after introduction of Helping Babies Breathe was maintained, and a further decrease over the five-year period was evident when analyses were adjusted for vulnerability of the newborns. Perinatal survival and performance of ventilation were significantly improved.

Digital Health Innovations, Tools, and Resources to Support Helping Babies Survive Programs

The Helping Babies Survive (HBS) initiative features a suite of evidence-based curricula and simulation-based training programs designed to provide health workers in low- and middle-income countries (LMICs) with the knowledge, skills, and competencies to prevent, recognize, and manage leading causes of newborn morbidity and mortality. Global scale-up of HBS initiatives has been rapid. As HBS initiatives rolled out across LMIC settings, numerous bottlenecks, gaps, and barriers to the effective, consistent dissemination and implementation of the programs, across both the pre- and in-service continuums, emerged. Within the first decade of expansive scale-up of HBS programs, mobile phone ownership and access to cellular networks have also concomitantly surged in LMICs. In this article, we describe a number of HBS digital health innovations and resources that have been developed from 2010 to 2020 to support education and training, data collection for monitoring and evaluation, clinical decision support, and quality improvement. Helping Babies Survive partners and stakeholders can potentially integrate the described digital tools with HBS dissemination and implementation efforts in a myriad of ways to support low-dose high-frequency skills practice, in-person refresher courses, continuing medical and nursing education, on-the-job training, or peer-to-peer learning, and strengthen data collection for key newborn care and quality improvement indicators and outcomes. Thoughtful integration of purpose-built digital health tools, innovations, and resources may assist HBS practitioners to more effectively disseminate and implement newborn care programs in LMICs, and facilitate progress toward the achievement of Sustainable Development Goal health goals, targets, and objectives.

Achieving Country-Wide Scale for Helping Babies Breathe and Helping Babies Survive

Helping Babies Breathe (HBB) was piloted in 2009 as a program targeted to reduce neonatal mortality (NM). The program has morphed into a suite of programs termed Helping Babies Survive that includes Essential Care for Every Baby. Since 2010, the HBB and Helping Babies Survive training programs have been taught to >850 000 providers in 80 countries. Initial HBB training is associated with a significant improvement in knowledge and skills. However, at refresher training, there is a knowledge-skill gap evident, with a falloff in skills. Accumulating evidence supports the role for frequent refresher resuscitation training in facilitating skills retention. Beyond skill acquisition, HBB has been associated with a significant reduction in early NM (<24 hours) and fresh stillbirth rates. To evaluate the large-scale impact of the growth of skilled birth attendants, we analyzed NM rates in sub-Saharan Africa (n = 11) and Nepal (as areas of growing HBB implementation). All have revealed a consistent reduction in NM at 28 days between 2009 and 2018; a mean reduction of 5.34%. The number of skilled birth attendants, an indirect measure of HBB sustained rollout, reveals significant correlation with NM, fresh stillbirth, and perinatal mortality rates, highlighting HBB's success and the need for continued efforts to train frontline providers. A novel live newborn resuscitation trainer as well as a novel app (HBB Prompt) have been developed, increasing knowledge and skills while providing simulation-based repeated practice. Ongoing challenges in sustaining resources (financial and other) for newborn programming emphasize the need for innovative implementation strategies and training tools.

Helping Babies Survive: Lessons Learned From Global Trainers

BACKGROUND

The Helping Babies Survive (HBS) suite of programs was launched in 2010 as an evidence-based educational package to train health care workers in low- and middle-income countries in neonatal resuscitation, immediate newborn care, and complications of prematurity. To date, there has been no purposeful examination of lessons learned from HBS trainers. Our intent with this study is to gather that data from the field.

METHODS

To estimate the total global reach of the HBS program, we obtained equipment distribution data from Laerdal and HBS material download data from the HBS Web site as of March 2020. To understand the lessons learned from HBS trainers, we examined comments from trainers who recorded their trainings on the HBS Web site, and other first-hand accounts.

RESULTS

More than 1 million pieces of equipment (simulators, flip charts, provider guides, and action plans) have been distributed worldwide. HBS materials have been downloaded from the Web site >130 000 times and have now been translated into 27 languages. HBS equipment and training has reached an estimated 850 000 providers in 158 countries. Qualitative analysis revealed 3 major themes critical to building successful and sustainable HBS programs: support, planning and local context, and subthemes for each.

CONCLUSIONS

Lessons learned from experienced trainers represent a vital distillation of first-hand experience into widely applicable knowledge to be used to reduce potential failures and achieve desired outcomes. Findings from this study offer further guidance on best practices for implementing and sustaining HBS programs and provide insight into challenges and successes experienced by HBS trainers.

Implementation of the Helping Babies Breathe Training Program: A Systematic Review

CONTEXT

Helping Babies Breathe (HBB) is a well-established neonatal resuscitation program designed to reduce newborn mortality in low-resource settings.

OBJECTIVES

In this literature review, we aim to identify challenges, knowledge gaps, and successes associated with each stage of HBB programming.

DATA SOURCES

Databases used in the systematic search included Medline, POPLINE, Cumulative Index to Nursing and Allied Health Literature, Latin American and Caribbean Health Sciences Literature, African Index Medicus, Cochrane, and Index Medicus.

STUDY SELECTION

All articles related to HBB, in any language, were included. Article quality was assessed by using the Grading of Recommendations Assessment, Development, and Evaluation framework.

DATA EXTRACTION

Data were extracted if related to HBB, including its implementation, acquisition and retention of HBB knowledge and skills, changes in provider behavior and clinical care, or the impact on newborn outcomes.

RESULTS

Ninety-four articles met inclusion criteria. Barriers to HBB implementation include staff turnover and limited time or focus on training and practice. Researchers of several studies found HBB cost-effective. Posttraining decline in knowledge and skills can be prevented with low-dose high-frequency refresher trainings, on-the-job practice, or similar interventions. Impact of HBB training on provider clinical practices varies. Although not universal, researchers in multiple studies have shown a significant association of decreased perinatal mortality with HBB implementation.

LIMITATIONS

In addition to not conducting a gray literature search, articles relating only to Essential Care for Every Baby or Essential Care for Small Babies were not included in this review.

CONCLUSIONS

Key challenges and requirements for success associated with each stage of HBB programming were identified. Despite challenges in obtaining neonatal mortality data, the program is widely believed to improve neonatal outcomes in resource-limited settings.

Using simulation to help healthcare professionals relaying patient information during telephone conversations

BACKGROUND

The purpose of this paper is to describe a development project in which simulation was used to improve the telephone-based conversations between nurses in an emergency department (ED) and physicians from different specialties taking care of acutely ill patients.

METHODS

A needs analysis consisting of observations and interviews was conducted and a one-day simulation-based interprofessional team training course was developed. Observations of phone conversations pre-course, three and six months after the course were conducted in the clinical setting with 20 participants in each point of time. A 14-item evaluation tool was used to record how many information pieces were communicated.

RESULTS

Five courses were conducted for 66 nurses/nurse assistants and 17 physicians. 9 out of the 14 items were reported significantly more after the course. Item that were not reported in the pre-measurement, increased to around 20% reporting three months after the course but then fell to close to 0% again after six months.

CONCLUSIONS

The patterns of retention and decrease of the effect could be an indicator for norms, values and beliefs held by professions about what constitutes their task.

Establishment of functional residual capacity at birth: Observational study of 821 neonatal resuscitations

AIM OF THE STUDY

Establishing functional residual capacity (FRC) during positive pressure ventilation (PPV) of apnoeic neonates is critical for survival. This may be difficult due to liquid-filled airways contributing to low lung compliance. The objectives were to describe initial PPV, changes in lung compliance and establishment of FRC in near-term/term neonates ≥36 weeks gestation at birth.

METHODS

Observational study of all neonatal resuscitations between 01.07.13 and 30.06.18 in a Tanzanian referral hospital. Perinatal events and characteristics were observed and recorded by trained research assistants. PPV were performed using self-inflating bag-masks without positive end-expiratory pressure (PEEP). Ventilation signals (pressure/flow), expired CO₂ (ECO₂) and heart rate were recorded by resuscitation monitors.

RESULTS

19,587 neonates were born, 1451 received PPV, of these 821 of median (p25, p75) birthweight 3180 (2844, 3500) grams and gestation 38 (37, 40) weeks had ≥20 ventilations and complete datasets. There was a significant increase in expired volume (from 3.3 to 6.0 ml/kg), ECO₂ (0.3-2.4%), lung compliance (0.13-0.19 ml/kg/mbar) and heart rate (109-138 beats/min) over the first 20 PPVs. Inflation volume, time, and peak inflation pressure (PIP) were stable around 12-13 ml/kg, 0.45 s, and 36 mbar, respectively.

CONCLUSIONS

The combination of increasing expired volumes, ECO₂, and heart rate with decreasing inflation/expired volume ratios and constant PIP, suggests establishment of FRC during the first 20 PPVs in near-term/term neonates using a self-inflating bag-mask without PEEP, the most common device worldwide for ventilating non-breathing neonates. Initial lung compliance is low, and with short inflation times, higher than recommended PIP seem necessary to deliver adequate tidal volumes.

Predictors of Helping Babies Breathe knowledge and skills among nurses in primary health settings in Dodoma region, Tanzania

Background

Globally, birth asphyxia is one of the leading causes of neonatal death. In Tanzania, neonatal deaths are estimated to be 25 deaths per 1000 live births and birth asphyxia accounts for 31% of those deaths.

Method

A cross-sectional study was conducted in 40 health centers within 7 districts in Dodoma Region among nurses working in maternity units. Simple random sampling was used to select participants. A knowledge questionnaire and performance skills checklist were used to assess nurses’ knowledge and skills respectively. Chi-square and binary logistic regression were employed to test association and identify significant predictors of HBB knowledge and skills.

Results

A total of 172 participants completed the study out of 176 recruited. This represents a respondent rate of 98%. Findings indicate that age, duration of professional training, and experience in maternity were significant predictors for knowledge and skills. However, after control of the confounders, experience in the maternity unit was found to be the only significant predictor of knowledge and skills in resuscitation of the neonates (AOR = 2.94; CI: 0.96–8.98; P = 0.05) and (AOR = 4.14; CI: 1.12–15.31; P = 0.03) respectively. Nurses with longer maternity nursing care experience of 5 years and above were better able to answer questions that demonstrated adequate knowledge (53.9%) and perform skills correctly (53.2%) related to HBB. Those with less than 5 years’ experience had limited knowledge (20%) and skills (10.5%).

Conclusion

In this setting, direct work experience in the maternity unit was the main factor influencing knowledge and skills in neonatal resuscitation with HBB.

Delivery of Positive End-Expiratory Pressure Using Self-Inflating Bags during Newborn Resuscitation Is Possible Despite Mask Leak

BACKGROUND

Ventilation is the key intervention to resuscitate non-breathing newborns. Positive end-expiratory pressure (PEEP) may facilitate lung-liquid clearance and help establish functional residual capacity.

OBJECTIVES

The aim of this study was to describe how mask leak and ventilation rates affect delivered PEEP and tidal volumes during newborn resuscitations using a self-inflating bag with an integrated PEEP valve.

METHODS

This was an observational study including near-term/term newborns who received bag-mask ventilation (BMV) with a new self-inflating bag with a novel 6 mbar PEEP valve, without external gas flow, between October 1, 2016 and June 30, 2018 in rural Tanzania. Helping Babies Breathe-trained midwives performed most of the resuscitations. Pressures and flow were continuously measured and recorded by resuscitation monitors.

RESULTS

In total, 198 newborns with a median gestation of 39 weeks (25th, 75th percentiles 37, 40) and birth weight of 3,100 g (2,580, 3,500) were included. The median delivered PEEP and expired (tidal) volume at different levels of mask leak were 6.0 mbar and 11.3 mL/kg at 0-20% mask leak, 5.5 mbar and 9.3 mL/kg at 20-40%, 5.2 mbar and 7.8 mL/kg at 40-60%, 4.6 mbar and 5.0 mL/kg at 60-80%, and 1.0 mbar and 0.6 mL/kg at 80-100% mask leak. A high ventilation rate (>60/min) nearly halved expired volumes compared to <60/min for 0-60% leak. The BMV rate had a negligible effect on peak inflation pressure (PIP) and PEEP.

CONCLUSIONS

Mask leak up to 80% did not impair the provision of recommended PEEP or tidal volumes during BMV with a self-inflating bag. High or low ventilation rates did not significantly affect PIP or PEEP. Expired volumes were reduced at ventilation rates >60/min.
