Barriers and technologies of maternal and neonatal referral system in developing countries: A narrative review

Delaying factors influencing the maternal health care disparities in developing countries: A scoping review

Maternal mortality is a critically significant issue in developing countries, where the lifetime risk for a woman in pregnancy or childbirth is approximately one in six. This elevated risk is often linked to delays in accessing and utilizing maternal health care services. Therefore, the study aims to provide a comprehensive understanding of the delaying factors influencing the maternal health care disparities in developing countries using Thaddeus and Maine's Three Delays Model. Researchers searched Science Direct, Pub Med, Pub Med Central, Embase, Medline, Simantic Scholar and Scopus to extract 69 case study articles published between 2015 and 2023 for this scoping review. The search reveals that among the three primary delay factors (Delay 1- patient, Delay 2- en-route or geographical, and Delay 3- service factors), patient-related factors contribute most to adverse outcomes across Asia, which is often deeply rooted in socio-economic and cultural discrepancy. All three delays significantly hinder maternal health care access in Africa with Delay 2 remaining a persistent challenge. Along with en-route causalities and security risks, many African countries face an acute shortage of emergency obstetric care infrastructure. While, increasing awareness and addressing cultural barriers are essential for achieving better health outcomes across Asia, expanding free maternal health care policies, reducing indirect costs and improving community engagement found to be more significant for African regions. In Latin American countries, Delay 3 is the primary challenge, driven by persistent disparities in health care quality, understaffing, and inconsistent service delivery. The study therefore concludes that bringing structural changes is utmost necessary by framing policies from grass root level understanding to reduce the prevailing maternal health care disparities in developing part of the world.

Referral Audit of Critically Ill Obstetric Patients: A Five-year Review from a Tertiary Care Health Facility in India

Background

In resource-limited facilities, the greatest number of unfavorable maternal-fetal outcomes at referral hospitals is chronicled from emergency obstetric referrals of critically ill patients from lower health facilities. An efficient obstetric referral system is thus necessitated for improving maternal health. Referral practices have not been optimized effectively till date, owing to paucity of a detailed profile of referred women and indigenous barriers encountered during implementation process.

Materials and methods

This five-year retrospective audit was conducted in the Department of Obstetrics and Gynecology, VMMC and Safdarjung Hospital, New Delhi from September 2018 to 2023, in which records of all critically ill obstetric women referred were reviewed. The primary outcomes included were proportion and pattern of patients being referred, while secondary outcomes included demographic variables, referring hospital, reason and number of steps in referral, duration of hospital stay and fetomaternal outcome. The data were recorded on a predesigned case proforma and analyzed using the SPSSv23 version of software, after application of appropriate statistical tests.

Results

The referral rate to obstetric intensive care unit (ICU) ranged from 39 to 47% in last 5 years; hypertensive disorder of pregnancy (31%) being the foremost cause of the referrals. Around 2/3rd women were transferred without escort (70%) or prior communication (90.6%) and referral slips were incomplete in half the admissions.

Conclusion

Ensuring emergency obstetric care (EmOC) at various levels by up-gradation of health infrastructure would go a long way in improving fetomaternal health outcomes. There is need of standardized referral slips tailor-made to each state and contextualized protocols for early recognition of complications and effective communication between referral centers.

Using digital technology as a platform to strengthen the continuum of care at community level for maternal, child and adolescent health in Tanzania: introducing the Afya-Tek program

Inadequate care within Tanzania's primary health system contributes to thousands of preventable maternal and child deaths, and unwanted pregnancies each year. A key contributor is lack of coordination between three primary healthcare actors: public sector Community Health Workers (CHWs) and health facilities, and private sector Accredited Drug Dispensing Outlets (ADDOs). The Afya-Tek program aims to improve the continuity of care amongst these actors in Kibaha district, through a mobile-application based digital referral system that focuses on improving maternal, child and adolescent health. The digital system called Afya-Tek was co-created with users and beneficiaries, and utilises open-source technology in-line with existing government systems. The system guides healthcare actors with individualised decision support during client visits and recommends accurate next steps (education, treatment, or referral). From July 2020 to June 2023, a total of 241,000 individuals were enrolled in the Afya-Tek program covering 7,557 pregnant women, 6,582 postpartum women, 45,900 children, and 25,700 adolescents. CHWs have conducted a total of 626,000 home visits to provide health services, including screening clients for danger signs. This has resulted in 38,100 referrals to health facilities and 24,300 linkages to ADDOs. At the ADDO level, 48,552 clients self-presented; 33% of children with pneumonia symptoms received Amoxicillin; 34% of children with diarrhoea symptoms received ORS and zinc; and 4,203 referrals were made to nearest health facilities. Adolescents preferred services at ADDOs as a result of increased perceived privacy and confidentiality. In total, 89% of all referrals were attended by health facilities. As the first digital health program in Tanzania to demonstrate the linkage among public and private sector primary healthcare actors, Afya-Tek holds promise to improve maternal, child and adolescent health as well as for scale-up and sustainability, through incorporation of other disease conditions and integration with government's Unified Community System (UCS).

Clinical characteristics and outcome of critically ill children referred to a tertiary hospital in Indonesia: a prospective observational study

BACKGROUND

The clinical characteristics of pediatric critically ill patients who need referral to a tertiary hospital is often unknown in resource limited settings where constraints in diagnosis capacity, resources, and infrastructures are common. There is a need to increase insight in the characteristics of these patients for capacity building strengthening and appropriate resource allocation. The aim of this study was to describe the clinical characteristics and outcomes of critically ill children who are referred to a tertiary referral teaching hospital in Yogyakarta.

METHODS

A prospective observasional study was carried out from July 1st, 2022 -January 31st, 2023 which included all critically ill pediatric patients who were referred through the Integrated Referral System (SISRUTE) to the Pediatric Intensive Care Unit (PICU) of dr. Sardjito hospital. We excluded patients who were referred with a request for admission to the PICU, but were not admitted to the PICU due to their stable condition and lack of the need for intensive care.

RESULT

During the study period, we received 1046 emergency referral requests for pediatric patients via SISRUTE, of those, 562 (53.7%) patients were critically ill. The reasons of PICU referral request were the need of solely intensive care 504 (89.7%), the need of multidisciplinary team care, including intensive care 57 (10.1%) and parents request 1 (0.3%). The pre-referral emergency diagnosis was shock 226 (40.3%), respiratory distress/failure 151 (26.7%), central nervous system (CNS) dysfunction 135 (24.1%), trauma 33 (5.9%) and sepsis 17 (3%). Of the 562 critically ill PICU referral requests, 473 (84.2%) requests were accepted. One hundred and eighty-one (58.7%) patients were finally admitted to the PICU, 125 (40.3%) admitted to our regular ward due to stable condition, 4 (1.3%) patients died in Emergency Departement (ED). The remaining accepted patients on request did not arrive in our facility due to various reasons. The mean (SD) response time was 9.1 (27.6) minutes. The mean (SD) transfer time was 6.45 (4.73) hours. Mean (SD) PICU and hospital length of stay was 6.7 (8.3) days and 10.2 (9.2) days respectively. PICU and hospital mortality was 24.3% and 29.7%, respectively.

CONCLUSION

The mortality rate for critically ill pediatric patients referred to a tertiary PICU still high, with shock being the most common pre-referral emergency diagnosis. There is a discrepancy between the referring hospital's and the referral hospital's indication for PICU admission. The time required to reach the referral hospital is quite lengthy.

Key barriers to the provision and utilization of maternal health services in low-and lower-middle-income countries; a scoping review

BACKGROUND

The preservation and promotion of maternal health (MH) emerge as vital global health objectives. Despite the considerable emphasis on MH, there are still serious challenges to equitable access to MH services in many countries. This review aimed to determine key barriers to the provision and utilization of MH services in low- and lower-middle-income countries (LLMICs).

METHODS

In this scoping review, we comprehensively searched four online databases from January 2000 to September 2022. In this study, the approach proposed by Arksey and O'Malley was used to perform the review. Consequently, 117 studies were selected for final analysis. To determine eligibility, three criteria of scoping reviews (population, concept, and context) were assessed alongside the fulfillment of the STROBE and CASP checklist criteria. To synthesize and analyze the extracted data we used the qualitative content analysis method.

RESULTS

The main challenges in the utilization of MH services in LLMICs are explained under four main themes including, knowledge barriers, barriers related to beliefs, attitudes and preferences, access barriers, and barriers related to family structure and power. Furthermore, the main barriers to the provision of MH services in these countries have been categorized into three main themes including, resource, equipment, and capital constraints, human resource barriers, and process defects in the provision of services.

CONCLUSIONS

The evidence from this study suggests that many of the barriers to the provision and utilization of MH services in LLMICs are interrelated. Therefore, in the first step, it is necessary to prioritize these factors by determining their relative importance according to the specific conditions of each country. Consequently, comprehensive policies should be developed using system modeling approaches.

Exploring gestational age, and birth weight assessment in Thatta district, Sindh, Pakistan: Healthcare providers' knowledge, practices, perceived barriers, and the potential of a mobile app for identifying preterm and low birth weight

INTRODUCTION

Reliable methods for identifying prematurity and low birth weight (LBW) are crucial to ending preventable deaths in newborns. This study explored healthcare providers' (HCPs) knowledge, practice, perceived barriers in assessing gestational age and birth weight and their referral methods for preterm and LBW infants. The study additionally assessed the potential of using a mobile app for the identification and referral decision of preterm and LBW.

METHODS

This qualitative descriptive study was conducted in Thatta District, Sindh, Pakistan. Participants, including doctors, nurses, lady health visitors, and midwives, were purposefully selected from a district headquarter hospital, and private providers in the catchment area of Global Network's Maternal and Newborn Health Registry (MNHR). Interviews were conducted using an interview guide after obtaining written informed consent. Audio recordings of the interviews were transcribed and analyzed using NVIVO® software with an inductive approach.

RESULTS

The HCPs had extensive knowledge about antenatal and postnatal methods for assessing gestational age. They expressed a preference for antenatal ultrasound due to the perceived accuracy, though accept practical barriers including workload, machine malfunctions, and cost. Postnatal assessment using the Ballard score was only undertaken sparingly due to insufficient training and subjectivity. All HCPs preferred electronic weighing scales for birth weight Barriers encountered included weighing scale calibration and battery issues. There was variation in the definition of prematurity and LBW, leading to delays in referral. Limited resources, inadequate education, and negative parent past experiences were barriers to referral. Foot length measurements were not currently being used. While mobile apps are felt to have potential, unreliable electricity supply and internet connectivity are barriers.

CONCLUSION

The HCPs in this study were knowledgeable in terms of potential tools, but acknowledged the logistical and parental barriers to implementation.

The Challenges of Implementing a Health Referral System in South Africa: A Qualitative Study

Introduction

Health system strengthening efforts also entails streamlining an existing referral system in a particular context to improve quality of health care offered to people. Conceptually, the referral system in South Africa, is seemingly sound. Nevertheless, gaps exist in its implementation. The aim of this study was to explore health care professionals' perceptions of referral system implementation in the Buffalo City Metropolitan Municipality (BCMM) in the Eastern Cape Province of South Africa.

Methods

This qualitative study included 12 health care professionals as participants. Each participant was interviewed using a semi-structured interview guide; with their consent, the interviews were audio recorded and transcribed verbatim. For data analysis, a thematic content analysis was used.

Results

The participants identified many impediments to the effective implementation of the referral system in BCCM. The main obstacles were deteriorating infrastructure, inadequate staffing, lack of transportation, and inadequate medical supplies and medications.

Conclusion

In mitigation, the participants proposed suggestions such as increasing the capacity of the health workforce, allocating personnel appropriately, increasing the availability of transportation, and providing essential medications to all levels of care. They also suggested involving all stakeholders in the referral process, providing education and training to health professionals on the referral system, and enhancing communication and feedback between the various levels of care. These challenges emphasised in this study highlight the need for targeted interventions to improve the referral system in this setting.

Barriers to proper maternal referral system in selected health facilities in Eastern Ethiopia: a qualitative study

BACKGROUND

Appropriate maternal referral system plays an essential role in curbing maternal mortality. Although the occurrence of obstetric complications is often unpredictable, addressing bottlenecks of the referral system is crucial to facilitate the women to have access to timely lifesaving interventions. Nonetheless, little is known about the barriers to maternal referral system in the eastern Ethiopia. Therefore, this study aimed to explore the barriers to maternal referral system at selected referral hospitals in eastern Ethiopia.

METHODS

Key informant interviews and in-depth interviews were conducted among purposively selected respondents who had a role in maternal referral processes. A total of 12 key informants that comprised of liaison officers, healthcare providers and three in-depth interviews with referred women were conducted. Semi-structured interview guide was developed and used to facilitate the interviews. All the interviews were tape recorded, complemented by note taking. Then audio recorded interviews were transcribed as per verbatim and imported to NVivo for coding and merging. The data were thematically synthesized.

RESULTS

The study identified a range of barriers that affect the maternal referral system in Eastern Ethiopia. The main barriers are grouped into three domains, such as: communication, transportation, and healthcare system. The most commonly reported barriers were lack of pre-referral communication and feedback, using informal communication, incomplete referral forms, poor ambulance service including misuse of ambulances, lack of skilled healthcare escort and lack of medical equipment at emergency, unnecessary self-referrals, poor referral skills and limited number of health professions.

CONCLUSIONS

The maternal referral system is overwhelmingly affected by lack of skill, logistics (referral form), misuse of available ambulance, poor communication, and limited seeking of feedback. Regular consultative meeting with relevant stakeholders and uptake of feedback are crucial to improve referral communication, proper use of ambulance and building capacity of health workforce about referral are essential to improve maternal referral system.

The "No bed syndrome" in Ghana - what, how and why? A literature, electronic and print media review

Objectives

"No bed syndrome" has become a familiar phrase in Ghana. Yet, there is very little in medical texts or the peer reviewed literature about it. This review aimed to document what the phrase means in the Ghanaian context, how and why it occurs, and potential solutions.

Design

A qualitative desk review using a thematic synthesis of grey and published literature, print and electronic media content covering the period January 2014 to February 2021. Text was coded line by line to identify themes and sub-themes related to the research questions. Analysis was manual and with Microsoft Excel to sort themes.

Setting

Ghana.

Participants and Intervention

Not applicable.

Results

"No bed syndrome" describes the turning away by hospitals and clinics of people seeking walk in or referral emergency care with the stated reasons "no bed available" or "all beds are full". There are reported cases of people dying while going round multiple hospitals seeking help and being repeatedly turned away because there is "no bed". The situation appears to be most acute in the highly urbanized and densely populated Greater Accra region. It is driven by a complex of factors related to context, health system functions, values, and priorities. The solutions that have been tried are fragmented rather than well-coordinated whole system reform.

Discussions and recommendations

The "no bed syndrome" describes the challenge of a poorly functioning emergency health care system rather than just the absence of a bed on which to place an emergency case. Many low and middle income countries have similar challenges with their emergency health care systems and this analysis from Ghana is potentially valuable in attracting global attention and thinking about emergency health systems capacity and reform in low and middle income countries. The solution to the "no bed syndrome" in Ghana requires reform of Ghana's emergency healthcare system that takes a whole system and integrated approach. All the components of the health system such as human resource, information systems, financing, equipment tools and supplies, management and leadership need to be examined and addressed together alongside health system values such as accountability, equity or fairness in the formulation, implementation, continuous monitoring and evaluation of policies and programs for system reform to expand and strengthen emergency healthcare system capacity and responsiveness. Despite the temptation to fall back on them as low hanging fruit, piecemeal and ad-hoc solutions cannot solve the problem.

Emergency obstetric referrals in public health facilities: A descriptive study from urban Maharashtra, India

Background

An effective referral system is key to access timely emergency obstetric care. The criticality of referrals makes it necessary to understand its pattern at the health system level. This study aims to document the patterns and primary reasons of obstetric case referral and the maternal and perinatal outcome of the cases in public health institutions in select areas of urban Maharashtra, India.

Methods

The study is based on the health records of public health facilities in Mumbai and its adjoining three municipal corporations. The information on pregnant women referred for obstetric emergencies was collected from patient referral forms of municipal maternity homes and peripheral health facilities between 2016 and 2019. Maternal and child outcome data was obtained from "Received-In" peripheral and tertiary health facilities to track whether the referred woman reached the referral facility for delivery. Descriptive statistics were used to analyze demographic details, referral patterns, reasons of referrals, referral communication and documentation, time and mode of transfer and delivery outcomes.

Results

14% (28,020) women were referred to higher health facilities. The most common reasons for referral were pregnancy-induced hypertension or eclampsia (17%), previous caesarean section (12%), fetal distress (11%) and Oligohydramnios (11%). 19% of all referrals were entirely due to unavailability of human resources or health infrastructure. Non-availability of emergency Operation Theatre (47%) and Neonatal Intensive Care Unit (45%) were the major non-medical reasons for referrals. Absence of health personnel such as anaesthetist (24%), paediatrician (22%), physician (20%) or obstetrician (12%) was another non-medical reason for referrals. Referring facility had a phone-based communication about the referral with the receiving facility in less than half of the cases (47%). 60% of the referred women could be tracked in higher health facilities. Of the tracked cases, 45% women delivered via caesarean section. Most of the deliveries (96%) resulted in live birth outcomes. 34% of the newborns weighed less than 2,500 grams.

Conclusion

Improving referral processes are critical to enhance the overall performance of emergency obstetric care. Our findings emphasize the need for a formal communication and feedback system between referring and receiving facilities. Simultaneously, ensuring EmOC at different levels of health facilities by upgradation of health infrastructure is recommended.

Factors Affecting Quality of Care in Maternal and Child Health in Timor-Leste: A Scoping Review

Timor-Leste faces many challenges implementing quality maternal, newborn and child health (MNCH) services due to resource constraints and socio-cultural factors that disproportionately affect the health of women and children. A scoping review was conducted to map the quality of MNCH services against WHO quality standards on: 1. Provision of care, 2. Experiences of care, and 3. Cross-cutting standards. The literature search identified 1058 citations, from which 28 full-text articles met the inclusion criteria. The findings highlight health workers' limited capacity to provide quality services and referrals. The major reasons for this are: a lack of essential supplies, poor infrastructure and transport, limited opportunities for ongoing learning, and gaps in health information systems. Provision of care standards and cross-cutting standards require attention at a broad systems level. Findings related to experiences of care highlight the importance of effective communication, respect, and emotional support, particularly for vulnerable women and children who have difficulty accessing services, and for those who have experienced violence. These experience-related standards could be addressed at an individual health worker and health service level, as well as at a systems level. This review provides direction to focus quality-improvement initiatives within local health facilities, as well as at municipal and national level.

Referral challenges and outcomes of neonates received at Muhimbili National Hospital, Dar es Salaam, Tanzania

Background

Functional referral system including pre referral care, access to emergency transport and ensuring continuity of care between facilities is critical for improved newborn health outcome. The neonatal transport system is quite undervalued in many sub Saharan countries, Tanzania included. This study assessed the pre referral care, transport process, ambulance characteristics, admission clinical status and outcomes of referred neonates at Muhimbili National Hospital Upanga, a tertiary facility in Dar es Salaam, Tanzania.

Methods

A descriptive cross sectional study with a longitudinal follow up was conducted from September 2020 to February 2021 including neonates referred to Muhimbili National Hospital. A structured questionnaire was used to collect demographic characteristics and transport factors including pre referral care extracted from the referral documents and through interviewing caregivers or escorting person/nurse. Ambulances were directly observed using a structured checklist on presence, absence and functionality of supportive equipment. All enrolled neonates had a clinical assessment at admission and 48 hours post admission to determine admission clinical status and 48 hours’ clinical outcome as either survived/died.

Results

Out of the 348 neonates assessed during the study period, the median gestation age was 38 weeks (IQR 32, 39) with the mean birth weight of 2455 ± 938 g. Pre referral documentation showed that temperature was measured in 176 (57.1%), oxygen saturation and random blood glucose in only 143 (46.6%) and 116 (36.2%) neonates respectively. Ambulance was used as a means of transportation in 308 (88.5%) neonates. While no ambulance had an incubator only 7 (2.0%) neonates were kept on a Kangaroo Mother Care position. Monitoring enroute was done to only 94 (27%) of the transferred neonates with 169 (54.9%) of health care professionals escorting the neonates lacking training on essential newborn care. On arrival, 115 (33%) were hypothermic, 74 (21.3%) hypoxic, 30 (8.6%) with poor perfusion and 49 (14.1%) hypoglycemic. Hypothermic neonates had an increased chance of dying compared to those who were normothermic (OR = 2.09, 95% CI (1.05–4.20), p = 0.037). The chance of dying among those presenting with hypoxia was almost three times (OR = 2.88, 95%CI (1.44–5.74), p = 0.003) while those with poor perfusion was almost five times (OR = 4.76, 95%CI (1.80–12.58), p = 0.002). Additionally, neonates who had hyperglycemia (RBG > 8.3mmol/l) on arrival had a higher probability of dying compared to those who were euglycemic [(OR = 3.10, 95% CI (1.19–8.09) p = 0.021]. Overall mortality was 22.4% within 48 hours of admission and risk of dying increased as the presence of poor clinical status added on.

Conclusion

Neonatal transportation in Dar es Salaam, Tanzania was observed to be challenging. Pre transfer care and monitoring during transportation was inadequate and this contributed to poor clinical status on admission. Hypothermia, hypoglycemia, hyperglycemia, hypoxia and poor perfusion on admission were associated with increased mortality. Effective referral network is needed for improved neonatal health outcomes. Pre referral supportive care, training of health care professionals, transportation with improved monitoring, clear communication protocol and referral documentation should be invested and effectively utilized.

Delineating natural catchment health districts with routinely collected health data from women's travel to give birth in Ghana

Background

Health service areas are essential for planning, policy and managing public health interventions. In this study, we delineate health service areas from routinely collected health data as a robust geographic basis for presenting access to maternal care indicators.

Methods

A zone design algorithm was adapted to delineate health service areas through a cross-sectional, ecological study design. Health sub-districts were merged into health service areas such that patient flows across boundaries were minimised. Delineated zones and existing administrative boundaries were used to provide estimates of access to maternal health services. We analysed secondary data comprising routinely collected health records from 32,921 women attending 27 hospitals to give birth, spatial demographic data, a service provision assessment on the quality of maternal healthcare and health sub-district boundaries from Eastern Region, Ghana.

Results

Clear patterns of cross border movement to give birth emerged from the analysis, but more women originated closer to the hospitals. After merging the 250 sub-districts in 33 districts, 11 health service areas were created. The minimum percent of internal flows of women giving birth within any health service area was 97.4%. Because the newly delineated boundaries are more “natural” and sensitive to observed flow patterns, when we calculated areal indicator estimates, they showed a marked improvement over the existing administrative boundaries, with the inclusion of a hospital in every health service area.

Conclusion

Health planning can be improved by using routine health data to delineate natural catchment health districts. In addition, data-driven geographic boundaries derived from public health events will improve areal health indicator estimates, planning and interventions.

Referral care for high-risk pregnant women in rural Rajasthan, India: a qualitative analysis of barriers and facilitators

Objective

To qualitatively assess the barriers and facilitators to uptake of referral services amongst high-risk pregnant women in rural Rajasthan.

Methods

A purposive sample of pregnant women with high-risk conditions requiring referral follow-up care (severe hypertension, moderate anemia, and severe anemia) were considered for inclusion. In-depth individual interviews were conducted in the local dialect, Mewari. Interviews were transcribed, coded, and organized for thematic generation as per the analytical framework described in the socio-ecological model.

Results

19 high risk pregnant women of low socioeconomic backgrounds across 15 villages were interviewed. Barriers to referral care included lack of transportation, household responsibilities, and limited awareness, education, and social support. The most prominent barrier was lack of accompaniment to the referral center by a family member or health worker. Facilitators included available husbands, engaged heath workers, supportive neighbors, and other female family members who shared past experiences.

Conclusions

Social support at the interpersonal and community level was key to overcoming referral care barriers faced by high-risk pregnant women in rural Rajasthan. Interventions that enhance social support may improve uptake of referral care services by high-risk pregnant women.

Aleatory-aware deep uncertainty quantification for transfer learning

The user does not have any idea about the credibility of outcomes from deep neural networks (DNN) when uncertainty quantification (UQ) is not employed. However, current Deep UQ classification models capture mostly epistemic uncertainty. Therefore, this paper aims to propose an aleatory-aware Deep UQ method for classification problems. First, we train DNNs through transfer learning and collect numeric output posteriors for all training samples instead of logical outputs. Then we determine the probability of happening a certain class from K-nearest output posteriors of the same DNN in training samples. We name this probability as opacity score, as the paper focuses on the detection of opacity on X-ray images. This score reflects the level of aleatory on the sample. When the NN is certain on the classification of the sample, the probability of happening a class becomes much higher than the probabilities of others. Probabilities for different classes become close to each other for a highly uncertain classification outcome. To capture the epistemic uncertainty, we train multiple DNNs with different random initializations, model selection, and augmentations to observe the effect of these training parameters on prediction and uncertainty. To reduce execution time, we first obtain features from the pre-trained NN. Then we apply features to the ensemble of fully connected layers to get the distribution of opacity score during the test. We also train several ResNet and DenseNet DNNs to observe the effect of model selection on prediction and uncertainty. The paper also demonstrates a patient referral framework based on the proposed uncertainty quantification. The scripts of the proposed method are available at the following link: https://github.com/dipuk0506/Aleatory-aware-UQ.

Interventions to improve obstetric emergency referral decision making, communication and feedback between health facilities in sub-Saharan Africa: A systematic review

Objective

The objective of the study was to review the evidence on interventions to improve obstetric emergency referral decision making, communication and feedback between health facilities in sub‐Saharan Africa (SSA).

Methods

A systematic search of PubMed, Embase, Cochrane Register and CINAHL Plus was conducted to identify studies on obstetric emergency referral in SSA. Studies were included based on pre‐defined eligibility criteria. Details of reported referral interventions were extracted and categorised. The Joanna Biggs Institute Critical Appraisal checklists were used for quality assessment of included studies. A formal narrative synthesis approach was used to summarise findings guided by the WHO's referral system flow.

Results

A total of 14 studies were included, with seven deemed high quality. Overall, 7 studies reported referral decision‐making interventions including training programmes for health facility and community health workers, use of a triage checklist and focused obstetric ultrasound, which resulted in improved knowledge and practice of recognising danger signs for referral. 9 studies reported on referral communication using mobile phones and referral letters/notes, resulting in increased communication between facilities despite telecommunication network failures. Referral decision making and communication interventions achieved a perceived reduction in maternal mortality. 2 studies focused on referral feedback, which improved collaboration between health facilities.

Conclusion

There is limited evidence on how well referral interventions work in sub‐Saharan Africa, and limited consensus regarding the framework underpinning the expected change. This review has led to the proposition of a logic model that can serve as the base for future evaluations which robustly expose the (in)efficiency of referral interventions.

Audit of documentation accompanying referred maternity cases to a referral hospital in northern Ghana: a mixed-methods study

Background

Effective referral of maternity cases, which cannot be managed at the primary healthcare level, with detailed referral forms is important for reducing possible delays in the provision of higher-level healthcare. This is the first study to audit documentation or referral forms that accompany referred maternity cases to a referral hospital in the northern region of Ghana.

Materials and methods

This study employed an explanatory sequential mixed-method design, starting with a quantitative review of referral forms that accompanied all patients referred to four units (antenatal, antenatal emergency, labour and neonatal intensive care) of a referral hospital in northern Ghana. In-depth interviews were held with the heads of the four units afterwards. Descriptive statistics were computed for the quantitative data. The qualitative data was subjected to content analysis. Integration of the data occurred at the data interpretation/discussion level.

Results

A total of 217 referral forms were analysed. Nearly half of the cases were referred from the Tamale Metropolis (46.5%) and 83.9% were referred for advanced care, whilst 8.3% were referred due to a lack of medical logistics and equipment such as oxygen and skilled personnel (6%). Completion rates of the referral forms were as follows: < 50% completion (n = 81; 37.3%), 50–75% completion (n = 112; 51.6%) above 75% completion (n = 24; 11.1%). Some of the handwriting were not legible and were quite difficult to read. The key informants stated that incomplete forms sometimes delay treatment. The head of the antenatal care unit at the referral hospital suggested professional development sessions as a strategy for supporting clinicians to fill the forms as expected.

Conclusion

The Ghana Health Service should conduct regular audits, develop job aides and provide incentives for health professionals who accurately complete referral forms. Completing forms and digitizing health records can help ensure further efficiencies in the health information system and sustain good maternity referral documentation practices.

Factors affecting the successful implementation of the referral system: A scoping review

An effective referral system ensures that there is a close relationship among all levels of health care, and individuals can receive the best possible care. The main purpose of the present study was to summarize studies that have addressed factors affecting the successful implementation of the referral system. A scoping review was performed to identify English and Farsi papers that were indexed in PubMed, Scopus, Science Direct, Trip Database, Cochrane Library, Embase, Google Scholar, SID, and Magiran until November 2020. Data was collected from the included studies by a reviewer and was checked by a second reviewer the collected data was analyzed using narrative methods. About 1245 relevant studies were identified in the first stage. After checking titles and abstracts, 63 studies were included. The factors that affected the referral system were classified in 4 themes and fourteen subthemes including technology (electronic referral, coordination, response and feedback), processes (effectiveness, efficiency), organizational (management, policy and planning, rules and regulations), patient centered individual (insurance coverage, social capital, transportation, awareness, attitude, satisfaction, and social influence). Therefore, a wide range of factors are affecting the performance of referral systems. For implementing an effective referral system, it is necessary to consider these factors.

Critical comparative analysis of data sources toward understanding referral during pregnancy and childbirth: three perspectives from Nigeria

BACKGROUND

The highest risk of maternal and perinatal deaths occurs during and shortly after childbirth and is preventable if functional referral systems enable women to reach appropriate health services when obstetric complications occur. Rising numbers of deliveries in health facilities, including in high mortality settings like Nigeria, require formalised coordination across the health system to ensure that women and newborns get to the right level of care, at the right time. This study describes and critically assesses the extent to which referral and its components can be captured using three different data sources from Nigeria, examining issues of data quality, validity, and usefulness for improving and monitoring obstetric care systems.

METHODS

The study included three data sources on referral for childbirth care in Nigeria: a nationally representative household survey, patient records from multiple facilities in a state, and patient records from the apex referral facility in a city. We conducted descriptive analyses of the extent to which referral status and components were captured across the three sources. We also iteratively developed a visual conceptual framework to guide our critical comparative analysis.

RESULTS

We found large differences in the proportion of women referred, and this reflected the different denominators and timings of the referral in each data source. Between 16 and 34% of referrals in the three sources originated in government hospitals, and lateral referrals (origin and destination facility of the same level) were observed in all three data sources. We found large gaps in the coverage of key components of referral as well as data gaps where this information was not routinely captured in facility-based sources.

CONCLUSIONS

Our analyses illustrated different perspectives from the national- to facility-level in the capture of the extent and components of obstetric referral. By triangulating across multiple data sources, we revealed the strengths and gaps within each approach in building a more complete picture of obstetric referral. We see our visual framework as assisting further research efforts to ensure all referral pathways are captured in order to better monitor and improve referral systems for women and newborns.

A retrospective review of gastroschisis epidemiology and referral patterns in northern Ghana

PURPOSE

To describe the epidemiology and referral patterns of gastroschisis patients in northern Ghana.

METHODS

A hospital-based retrospective review was undertaken at Tamale Teaching Hospital (TTH) Neonatal Intensive Care Unit (NICU) between 2014 and 2019. Data from gastroschisis patients were compared to patients with other surgical diagnoses. Descriptive and inferential statistics were performed with SAS. Referral flow maps were made with ArcGIS.

RESULTS

From a total of 360 neonates admitted with surgical conditions, 12 (3%) were diagnosed with gastroschisis. Around 91% (n = 10) of gastroschisis patients were referred from other hospitals, traveling 4 h, on average. Referral patterns showed gastroschisis patients were admitted from three regions, whereas patients with other surgical diagnoses were admitted from eight regions. Only 6% (12/201) of expected gastroschisis cases were reported during the 6-year period in all regions. All gastroschisis deaths occurred within the first week of life.

CONCLUSIONS

Improving access to surgical care and reducing neonatal mortality related to gastroschisis in northern Ghana is critical. This study provides a baseline to inform future gastroschisis interventions at TTH. Priority areas may include special management of low birth weight newborns, better referral systems, empowerment of community health workers, and increasing access to timely, affordable, and safe neonatal transport.

Barriers in Health Information Systems and Technologies to Support Maternal and Neonatal Referrals at Primary Health Centers

Objectives

This study explored health workers’ perceptions and experiences regarding the maternal and neonatal referral system, focusing on barriers of health information systems and technologies (IS/IT) at primary health centers (PHCs) in South Tangerang, Indonesia.

Methods

This qualitative study was conducted using semi-structured interviews, which were conducted at the South Tangerang District Health Office and three PHCs. Interviews were conducted with nine participants responsible for maternal and neonatal referrals in their organizations. The data were analyzed using qualitative content analysis.

Results

In South Tangerang, the Primary Health Care Information System (SIMPUS) is used to register patients and record data on medical treatment. To facilitate referrals, the PHCs currently use the Integrated Referral Information System (SISRUTE), P-Care, and the Integrated Emergency Management System (SPGDT). The following four IS/IT barriers to support maternal and neonatal referrals were found: technology, human resources, organizational support, and the referral process and implementation.

Conclusions

The barriers in technology, human resources, and organizational support cause problems in the maternal and neonatal referral process and in the implementation of referrals. Barriers to referrals can influence patients’ ability to receive appropriate care in a timely fashion and lead to inefficiency in maternal and neonatal referrals. This study contributes knowledge about IS/IT implementation in maternal and neonatal referral systems and provides recommendations to health regulators and application developers for the implementation of IS/IT in Indonesia.

Midwives' perceived role in up referral of high-risk pregnancies in primary healthcare settings, eThekwini district, South Africa

Background

South African maternal and neonatal mortality rates remain unnecessarily high, which are considered avoidable through timeous identification, treatment and referral. An efficient referral process of high-risk pregnant women is dependent on the midwives’ ability to respond with relevance to the maternal and neonatal healthcare needs. The attainment of improved maternal and neonatal outcomes commences at the primary healthcare level, with the midwife, recognised as the first person responsible and accountable for pregnant women’s healthcare.

Aim

To explore midwives’ perceptions of their role in the referral of high-risk pregnant women from primary health care clinics to expert-centred sites.

Methods

A qualitative, exploratory, descriptive in nature approach, underpinned by a social constructivism paradigm, guided the methodology. Purposive sampling was used to select both the primary health care clinics in the feeder zone and the registered midwives working in these clinics. Data were collected through four focus group discussions and analysed using content analysis. The principles of trustworthiness were observed.

Setting

Department of Health primary health care clinics in the eThekwini district, South Africa.

Results

The midwives understood their role in the up referral of high-risk pregnant women but experienced many interruptions in its execution. Four categories emerged from the data, namely, enhanced by team support in the clinics, restrictions in transfer to expert-centred sites, impeding social determinants and midwifery competence facilitates referral process.

Conclusion

Global initiatives cannot guarantee maternal and neonatal health because of the challenges experienced by the midwives in the execution of their roles as they interface with the healthcare team.

Health care workers' experiences of managing foetal distress and birth asphyxia at health facilities in Northern Uganda

BACKGROUND

Birth asphyxia is one of the leading causes of intrapartum stillbirth and neonatal mortality worldwide. We sought to explore the experiences of health care workers in managing foetal distress and birth asphyxia to gain an understanding of the challenges in a low-income setting.

METHODS

We conducted in-depth interviews with 12 midwives and 4 doctors working in maternity units from different health facilities in Northern Uganda in 2018. We used a semi-structured interview guide which included questions related to; health care workers' experiences of maternity care, care for foetal distress and birth asphyxia, views on possible preventive actions and perspectives of the community. Audio recorded interviews were transcribed verbatim and analysed using inductive content analysis.

RESULTS

Four categories emerged: (i) Understanding of and actions for foetal distress and birth asphyxia including knowledge, misconception and interventions; (ii) Challenges of managing foetal distress and birth asphyxia such as complexities of the referral system, refusal of referral, lack of equipment, and human resource problems, (iii) Expectations and blame from the community, and finally (iv) Health care worker' insights into prevention of foetal distress and birth asphyxia.

CONCLUSION

Health care workers described management of foetal distress and birth asphyxia as complex and challenging. Thus, guidelines to manage foetal distress and birth asphyxia that are specifically tailored to the different levels of health facilities to ensure high quality of care and reduction of need for referral are called for. Innovative ways to operationalise transportation for referral and community dialogues could lead to improved birth experiences and outcomes.

Quality and women's satisfaction with maternal referral practices in sub-Saharan African low and lower-middle income countries: a systematic review

Background

sub-Saharan African Low and Lower-Middle Income Countries (sSA LLMICs) have the highest burden of maternal and perinatal morbidity and mortality in the world. Timely and appropriate maternal referral to a suitable health facility is an indicator of effective health systems. In this systematic review we aimed to identify which referral practices are delivered according to accepted standards for pregnant women and newborns in sSA LLMICs by competent healthcare providers in line with the needs of pregnant women.

Methods

Six electronic databases were systematically searched for primary data studies (2009–2018) in English reporting on maternal referral practices and their effectiveness. We conducted a content analysis guided by a framework for assessing the quality of maternal referral. Quality referral was defined as: timely identification of signal functions, established guidelines or standards, adequate documentation, staff accompaniment and prompt care by competent healthcare providers in the receiving facility.

Results

Seventeen articles were included in the study. Most studies were quantitative (n = 11). Two studies reported that women were dissatisfied due to delays in referral processes that affected their health. Most articles (10) reported that women were not accompanied to higher levels of care, delays in referral processes, transport challenges and poor referral documentation. Some healthcare providers administered essential drugs such as misoprostol prior to referral.

Conclusions

Efforts to improve maternal health in LLMICs should aim to enhance maternity care providers’ ability to identify conditions that demand referral. Low cost transport is needed to mitigate barriers of referral. To ensure quality maternal referral, district level health managers should be trained and equipped with the skills needed to monitor and evaluate referral documentation, including quality and efficiency of maternal referrals.

Referral systems for preterm, low birth weight, and sick newborns in Ethiopia: a qualitative assessment

BACKGROUND

A responsive and well-functioning newborn referral system is a cornerstone to the continuum of child health care; however, health system and client-related barriers negatively impact the referral system. Due to the complexity and multifaceted nature of newborn referral processes, studies on newborn referral systems have been limited. The objective of this study was to assess the barriers for effective functioning of the referral system for preterm, low birth weight, and sick newborns across the primary health care units in 3 contrasting regions of Ethiopia.

METHODS

A qualitative assessment using interviews with mothers of preterm, low birth weight, and sick newborns, interviews with facility leaders, and focus group discussions with health care providers was conducted in selected health facilities. Data were coded using an iteratively developed codebook and synthesized using thematic content analysis.

RESULTS

Gaps and barriers in the newborn referral system were identified in 3 areas: transport and referral communication; availability of, and adherence to newborn referral protocols; and family reluctance or refusal of newborn referral. Specifically, the most commonly noted barriers in both urban and rural settings were lack of ambulance, uncoordinated referral and return referral communications between providers and between facilities, unavailability or non-adherence to newborn referral protocols, family fear of the unknown, expectation of infant death despite referral, and patient costs related to referral.

CONCLUSIONS

As the Ethiopian Federal Ministry of Health focuses on averting early child deaths, government investments in newborn referral systems and standardizing referral and return referral communication are urgently needed. A complimentary approach is to lessen referral overload at higher-level facilities through improvements in the scope and quality of services at lower health system tiers to provide basic and advanced newborn care.

Working with lay midwives to improve the detection of neonatal complications in rural Guatemala

Background

Globally most neonatal deaths occur within the first week of life and in low-income and middle-income countries. Strengthening health system linkages for frontline providers—such as lay midwives providing home-based obstetrical care—may improve neonatal outcomes in these settings. Here, we conducted a quality improvement study to increase the detection of neonatal complications by lay midwives in rural Guatemala, thereby increasing referrals to a higher level of care.

Methods

A quality improvement team in Guatemala reviewed drivers of neonatal health services provided by lay midwives. Improvement interventions included training on neonatal warning signs, optimised mobile health technology to standardise assessments and financial incentives for providers. The primary quality outcome was the rate of neonatal referral to a higher level of care.

Results

From September 2017 to September 2018, participating midwives attended 869 home deliveries and referred 80 neonates to a higher level of care. A proportion control chart, using the preintervention period from January to September 2017 as the baseline, showed an increase in the referral rate of all births from 1.5% to 9.9%. Special cause was obtained in January 2018 and sustained except for May 2018. The proportion of neonates receiving assessments by midwives in the first week of life increased to >90%. A trend toward an increasing number of days between neonatal deaths did not attain special cause.

Conclusions

Structured improvement interventions, including mobile health decision support and financial incentives, significantly increased the detection of neonatal complications and referral of neonates to higher levels of care by lay midwives operating in rural home-based settings in Guatemala. The results show the value of improving the integration of lay midwives and other first responders into neonatal systems of care in low-resource settings.
