Factors influencing the use of magnesium sulphate in pre-eclampsia/eclampsia management in health facilities in Northern Nigeria: a mixed methods study

Comparison of Zuspan regimen and its 12-hour modification in women with severe pre-eclampsia and eclampsia in two hospitals in Abeokuta

BACKGROUND

Hypertensive disorders in pregnancy (HDP) are leading causes of maternal mortality (with severe pre-eclampsia/eclampsia [SPE/EC] being causes of death). Magnesium sulphate (MgSO₄) has proven to be the drug of choice for SPE/EC management. However, its availability and cost remain a drawback to its use in developing countries. This study aimed to compare Zuspan regimen with its 12-hour modification for SPE/EC management in two major hospitals in Abeokuta, Ogun state, South Western Nigeria.

METHODS

A randomized controlled trial of non-inferior parallel design carried out at Federal Medical Centre and Sacred Heart Hospital, Abeokuta involving 148 consenting women who were randomized into two groups A and B. Both groups had 4 g loading dose of MgSO4, but the duration of maintenance was reduced to 12-hours in Group A (intervention) while Group B received the standard Zuspan regimen (control). Outcome measures were the occurrence/recurrence of convulsions (primary), maternal side effects and perinatal outcomes (secondary).

RESULTS

There was no statistically significant difference in the occurrence/recurrence of seizures between the two groups for both SPE/EC. No signs of maternal toxicity were observed in both arm of the study. There were no statistically significant differences in the perinatal/neonatal death and Apgar scores at 1 and 5 min. However, there was a significant increase in the number of days on admission in the control group of those neonates delivered to mothers with eclampsia.

CONCLUSION

A 12-hr modification of Zuspan regimen was found to be non-inferior to the standard Zuspan regimen in the management of SPE/EC.

Factors affecting use of magnesium sulphate for pre-eclampsia or eclampsia: a qualitative evidence synthesis

Background

Hypertensive disorders account for 14% of global maternal deaths. Magnesium sulphate (MgSO₄) is recommended for prevention and treatment of pre‐eclampsia/eclampsia. However, MgSO₄ remains underused, particularly in low‐ and middle‐income countries (LMICs).

Objective

This qualitative evidence synthesis explores perceptions and experiences of healthcare providers, administrators and policy‐makers regarding factors affecting use of MgSO₄ to prevent or treat pre‐eclampsia/eclampsia.

Search strategy

We searched MEDLINE, EMBASE, Emcare, CINAHL, Global Health and Global Index Medicus, and grey literature for studies published between January 1995 and June 2021.

Selection criteria

Primary qualitative and mixed‐methods studies on factors affecting use of MgSO₄ in healthcare settings, from the perspectives of healthcare providers, administrators and policy‐makers, were eligible for inclusion.

Data collection and analysis

We applied a thematic synthesis approach to analysis, using COM‐B behaviour change theory to map factors affecting appropriate use of MgSO₄.

Main results

We included 22 studies, predominantly from LMICs. Key themes included provider competence and confidence administering MgSO₄ (attitudes and beliefs, complexities of administering, knowledge and experience), capability of health systems to ensure MgSO₄ availability at point of use (availability, resourcing and pathways to care) and knowledge translation (dissemination of research and recommendations). Within each COM‐B domain, we mapped facilitators and barriers to physical and psychological capability, physical and social opportunity, and how the interplay between these domains influences motivation.

Conclusions

These findings can inform policy and guideline development and improve implementation of MgSO₄ in clinical care. Such action is needed to ensure this life‐saving treatment is widely available and appropriately used.

The ability and safety of community-based health workers to safely initiate lifesaving therapies for pre-eclampsia in Ogun State, Nigeria: An analysis of 260 community treatments with MgSO4 and/or methyldopa

OBJECTIVES

To evaluate community-based health workers' ability to identify cases of hypertension in pregnancy, safely deliver methyldopa and magnesium sulphate and make referrals when appropriate.

STUDY DESIGN

This was part of Nigeria Community-Level Interventions for Pre-eclampsia (CLIP) cluster randomized controlled trial (NCT01911494). Community-based Health Workers (CHW) recruited pregnant women from five Local Government Areas (clusters) and used mobile health aid for clinical assessment of pre-eclampsia.

MAIN OUTCOME MEASURES

The primary outcome was the number of adverse events that occurred after the administration of magnesium sulphate and/or methyldopa to pregnant women by CHWs.

FINDINGS

Of 8790 women receiving mobile health-guided care, community-based health workers in Nigeria provided 309 women with hypertension (4.2% of delivered women), and safely administered 142 doses of intramuscular magnesium sulphate. Community Heath Extension Workers (CHEWs) and nurses gave fifty-two and sixty-seven doses of intramuscular magnesium sulphate respectively, twenty-three doses were given by other health care workers (midwives, community health officers, health assistants). The high rate of administration by nurses can be explained by turf protection as well as their seniority within the health system. Also, CHEWs and nurses gave 124 doses of oral methyldopa and 126 urgent referrals were completed. There were no complications related to administration of treatment or referral.

INTERPRETATION

These findings demonstrate the ability of community-based health workers to safely administer methyldopa and intramuscular magnesium sulphate. The use of task-sharing, therefore, could drastically reduce the three delays (triage, transport and treatment) associated with high maternal mortality and morbidity in rural communities in low- and middle-income countries.

Perceptions of midwives on the quality of emergency obstetric care at hospitals in Ethiopia: A qualitative explanatory study

BACKGROUND

In Ethiopia, maternal mortality remains an important public health concern. High maternal mortality is attributed in part to the poor quality of obstetric care. This study was designed to investigate perceptions of midwives about the quality of emergency obstetric care provided at hospitals in the Harari region of Ethiopia.

METHODS

An explanatory qualitative study was conducted from December 2018 to February 2019 at public and private hospitals in the Harari region, Ethiopia. The data were obtained through in-depth interviews with 12 midwives working in maternity units. The interviewers took notes and audio-recorded the respondents' descriptions. Braun and Clarke's thematic analysis method was employed to analyse the data using Nvivo 12 qualitative data analysis software.

RESULTS

Poorly designed infrastructure, including a scarcity of beds, rooms and ambulances challenged the provision of quality obstetric services. Midwives working at hospitals were inadequate in number and training opportunities were scarce. Language barriers affected effective communication between patients and caregivers. Frequent disruptions to medical supplies resulted in the provision of suboptimal obstetric care as it created an inability to provide appropriate medications. A lack of treatment protocols, poor supportive supervision, and poor staff motivation impaired the provision of quality obstetric care at hospitals, although disparities were observed among hospitals in this regard.

CONCLUSIONS

Several interdependent factors limited the quality of emergency obstetric care at hospitals in the region. Quality improvement initiatives and equitable resource distribution for hospitals need to be enhanced while the existing health infrastructure, resources and service delivery management need to be strengthened.

Knowledge on Prevention and Management of Preeclampsia and Eclampsia among Nurses in Primary Health Settings: Baseline Findings from an Interventional Study in Dodoma Region, Tanzania

Background:

Preeclampsia and eclampsia are conditions which increase maternal and foetal morbidity and mortality worldwide. These conditions are ranked as the second leading cause of maternal deaths. Nurses have a critical role in preventing and managing preeclampsia. However, their knowledge has not been evaluated particularly among those working in primary health facilities, where opportunities for continue education is limited.

Objective:

To assess knowledge on prevention and management of preeclampsia and eclampsia among nurses working in the primary health care settings.

Methods:

Analysis of baseline data from an intervention study which test the effectiveness of simulation-based training on obstetric and neonatal emergencies among nurses in managing maternal and newborn emergencies in primary health care settings. A total of 39 primary health centres within 7 districts in Dodoma Region were selected to take part in the interventional study. Individual participants were nurses working in maternity units were involved. 172 nurses were selected using a simple random method. Nurses' knowledge on prevention and management of PEE and its predictors were assessed using a self-administered questionnaire. Descriptive statistics analysis was done to determine the distribution of the background characteristics of nurses and logistic regression analysis was performed to explore predictors of nurses' knowledge

Results:

Overall knowledge on preeclampsia and eclampsia was 88 (51.2%). Professional qualification was a predictor associated with a nurse's knowledge about preeclampsia and eclampsia. Registered nurses were more knowledgeable compared to enrolled nurses (AOR3.311; CI, 1.62 to 6.768; P value =.001), years of working experience showed no association with knowledge on preeclampsia and eclampsia (AOR 0.98; CI: 0.39-2.47; P values = 0.970)

Conclusion:

This study showed there is a critical knowledge deficiency in the prevention and management of preeclampsia and eclampsia among nurses working in maternal units of primary health care setting. Effective regular training on prevention and management of preeclampsia and eclampsia for frontline nurses is required in order to improve maternal and neonatal survival.

Perception of Midwives Towards Magnesium Sulfate Use at Chatinkha Maternity Wing in Blantyre, Malawi: A Qualitative Study

Introduction

Globally, magnesium sulfate (MgSO₄) has been recognized as the drug of choice for preventing and controlling fits among women with severe pre-eclampsia and eclampsia, respectively. Improper use of magnesium sulfate has been reported globally. Therefore, actionable findings for improving magnesium sulfate use are needed. This study aims at understanding the views of midwives towards MgSO₄ use to inform an intervention whose objective is to improve MgSO₄ use among the midwives.

Methods

An exploratory qualitative study was conducted from July to September 2018. We conducted 10 in-depth interviews and a focus group discussion with midwives. All the interviews were audio taped and transcribed verbatim. Data were managed by NVivo version 10.0 and analyzed thematically.

Results

We identified one overarching theme: “Inadequate governing approaches on management of clients on MgSO₄” with corresponding subthemes; in adequate preparation on magnesium sulfate administration; inconsistent formula, regimen and guidelines/protocols on magnesium sulfate use and lack of resources.

Conclusion

Midwives perceived MgSO₄ use as a demanding activity due to inadequate training, inconsistent tools, and lack of resources. While periodic in-service training should be intensified to improve MgSO₄ use, necessary resources should be provided, such as blood pressure machines, more midwives, and protocols.

The WHO Safe Childbirth Checklist implementation: impact on the prescription of magnesium sulphate through a one-year longitudinal study

BACKGROUND

Preeclampsia is a relatively frequent condition during pregnancy and childbirth. The administration of magnesium sulphate as a prophylactic and treatment measure is an evidence-based practice for eclampsia; however, it is not consistently used, compromising the health of pregnant women. This study aimed to assess compliance with recommendations of the International Society for the Study of Hypertension in Pregnancy (ISSHP) for the use of MgSO₄ in pregnant women with preeclampsia, before and after the implementation of the World Health Organization Safe Childbirth Checklist (SCC).

METHODS

This quasi-experimental study was conducted between July 2015 and July 2016 at a third-level maternity hospital in northeastern Brazil, where the SCC was implemented. Compliance (underuse and overuse of MgSO₄) was assessed in biweekly samples of 30 deliveries assessed 6 months before and 6 months after SCC implementation, using indicators based on international guidelines. A total of 720 deliveries were assessed over 1 year using an ad hoc application for reviewing medical records. Aggregated adequate use was estimated for the study period, and the time series measurements were compared to a control chart to assess change.

RESULTS

The incidence of preeclampsia was 39.9% (287/720). Among these, 64.8% (186/287) had severe signs or symptoms and needed MgSO₄. Underuse (no prescription when needed) of MgSO₄ was observed in 74.7% (139/186) of women who needed the drug. Considering all women, non-compliance with the prescription protocol (underuse and overuse) was 20.0% (144/720). After introducing the SCC, the use of MgSO₄ in women with preeclampsia with severe features increased from 19.1 to 34.2% (p = 0.025). Longitudinal analysis showed a significant (p < 0.05) ascending curve of adequate use of MgSO₄ after the SCC was implemented.

CONCLUSIONS

Compliance with recommendations for the use of MgSO₄ in preeclampsia was low, but improved after implementation of the SCC. Interventions to improve compliance based on diagnosis and treatment reminders may help in the implementation of this good practice.

Referral linkage among public health facilities in Ethiopia: A qualitative explanatory study of facilitators and barriers for emergency obstetric referral in Addis Ababa city administration

BACKGROUND

In developing countries including Ethiopia, maternal mortality ratio remains unacceptably high. During pregnancy and childbirth, a woman may acquire one or more of obstetric complications including hemorrhage, sepsis, hypertension and obstructed labor. Early diagnosed and referral of women who experienced obstetric complications to a specialty center can save the life of women and babies. However, several factors might affect the referral procedures of these women. Therefore, this study was aimed at assessing the facilitators and barriers of obstetric referral in selected public health facilities of Addis Ababa city administration, Ethiopia.

METHODS

A qualitative study design was employed to obtain the narratives of 12 healthcare workers and three recently referred mothers. The study included a regional health bureau, a lead hospital and a health center. Thematic analysis was employed to present to present the findings of the study and open code software was used to code and generate the themes.

RESULTS

This study revealed several barriers and some facilitators of obstetric referral. Early identification of complications, exercising teamwork, availability of referral protocol, availability of ambulance and effective communication system were the major reported factors which enhanced obstetric referral. Several themes including poor perception of clients, poor supportive supervision, lack of staff motivation and shortage of beds and medical equipment, lack of competence among the staffs and shortage of ambulance at health center were emerged as barriers of obstetric referral.

CONCLUSIONS

This study revealed several barriers of obstetric referral in the Addis Ababa city administration although a number of facilitators of obstetric referral exist. All of the reported barriers are related to the existing health system that need a collective action of all the actors to eliminate the barriers while enhancing the facilitators of obstetric referral.

Detecting and managing hypertensive disorders in pregnancy: a cross-sectional analysis of the quality of antenatal care in Nigeria

BACKGROUND

Nigeria has one of the highest rates of maternal mortality in the world (576/100,000 births), with a significant proportion of death attributed to hypertensive disorders in pregnancy (HDPs). High quality antenatal care (ANC) plays a crucial role in early detection and management of HDPs. We conducted an assessment of quality of antenatal care, and its capacity to detect and manage HDPs, in two tiers of Nigerian facilities, with the aim of describing the state of service delivery and identifying the most urgent gaps.

METHODS

Quality of antenatal care was assessed and compared between primary healthcare centers (PHCs) (n = 56) and hospitals (secondary + tertiary facilities, n = 39) in seven states of Nigeria. A cross-sectional design captured quality of care using facility inventory checklists, semi-structured interviews with healthcare providers and clients, and observations of ANC consultations. A quality of care framework and scoring system was established based on aspects of structure, process, and outcome. Average scores were compared using independent sample t-tests and measures of effect were assessed by multivariate linear regression.

RESULTS

All domains of quality except provider interpersonal skills scored below 55%. The lowest overall scores were observed in provider knowledge (49.9%) and provider technical skill (47.7%). PHCs performed significantly worse than hospitals in all elements of quality except for provider interpersonal skills. Provider knowledge was significantly associated with their level of designation (i.e., obstetrician vs. other providers).

CONCLUSIONS

In order to provide high quality care, ANC in Nigeria must experience massive improvements to inventory, infrastructure and provider knowledge and training. In particular, ANC programs in PHCs must be revitalized to minimize the disparity in quality of care provided between PHCs and hospitals. The relatively low quality of care observed may be contributing to Nigeria's high rate of maternal mortality and burden of disease attributed to HDPs.

Barriers to access and utilization of emergency obstetric care at health facilities in sub-Saharan Africa: a systematic review of literature

BACKGROUND

Nearly 15% of pregnancies end in fatal perinatal obstetric complications including bleeding, infections, hypertension, obstructed labour and complications of abortion. Globally, an estimated 10.7 million women have died due to obstetric complications in the last two decades, and two thirds of these deaths occurred in sub-Saharan Africa. Though the majority of maternal mortalities can be prevented, different factors can hinder women's access to emergency obstetric services. Therefore, this review is aimed at synthesizing current evidence on barriers to access and utilization of emergency obstetric care in sub-Saharan Africa.

METHODS

Articles were searched from MEDLINE, CINAHL, EMBASE, and Maternity and Infant Care databases using predefined search terms and strategies. Articles published in English, between 2010 and 2017, were included. Two reviewers (AG and AM) independently screened the articles, and data extraction was conducted using the Joanna Briggs Institute data extraction format. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool. The identified barriers were qualitatively synthesized and reported using the Three Delays analytical framework. The PRISMA checklist was employed to present the findings.

RESULT

The search of the selected databases returned 3534 articles. After duplicates were removed and further screening undertaken, 37 studies fulfilled the inclusion criteria. The identified key barriers related to the first delay included younger age, illiteracy, lower income, unemployment, poor health service utilization, a lower level of assertiveness among women, poor knowledge about obstetric danger signs, and cultural beliefs. Poorly designed roads, lack of vehicles, transportation costs, and distance from facilities led to the second delay. Barriers related to the third delay included lack of emergency obstetric care services and supplies, shortage of trained staff, poor management of emergency obstetric care provision, cost of services, long waiting times, poor referral practices, and poor coordination among staff.

CONCLUSIONS

A number of factors were found to hamper access to and utilization of emergency obstetric care among women in sub-Saharan Africa. These barriers are inter-dependent and occurred at multiple levels either at home, on the way to health facilities, or at the facilities. Therefore, country-specific holistic strategies including improvements to healthcare systems and the socio-economic status of women need to be strengthened. Further research should focus on the assessment of the third delay, as little is known about facility-readiness.

Factors that influence the provision of intrapartum and postnatal care by skilled birth attendants in low- and middle-income countries: a qualitative evidence synthesis

BACKGROUND

In many low- and middle-income countries women are encouraged to give birth in clinics and hospitals so that they can receive care from skilled birth attendants. A skilled birth attendant (SBA) is a health worker such as a midwife, doctor, or nurse who is trained to manage normal pregnancy and childbirth. (S)he is also trained to identify, manage, and refer any health problems that arise for mother and baby. The skills, attitudes and behaviour of SBAs, and the extent to which they work in an enabling working environment, impact on the quality of care provided. If any of these factors are missing, mothers and babies are likely to receive suboptimal care.

OBJECTIVES

To explore the views, experiences, and behaviours of skilled birth attendants and those who support them; to identify factors that influence the delivery of intrapartum and postnatal care in low- and middle-income countries; and to explore the extent to which these factors were reflected in intervention studies.

SEARCH METHODS

Our search strategies specified key and free text terms related to the perinatal period, and the health provider, and included methodological filters for qualitative evidence syntheses and for low- and middle-income countries. We searched MEDLINE, OvidSP (searched 21 November 2016), Embase, OvidSP (searched 28 November 2016), PsycINFO, OvidSP (searched 30 November 2016), POPLINE, K4Health (searched 30 November 2016), CINAHL, EBSCOhost (searched 30 November 2016), ProQuest Dissertations and Theses (searched 15 August 2013), Web of Science (searched 1 December 2016), World Health Organization Reproductive Health Library (searched 16 August 2013), and World Health Organization Global Health Library for WHO databases (searched 1 December 2016).

SELECTION CRITERIA

We included qualitative studies that focused on the views, experiences, and behaviours of SBAs and those who work with them as part of the team. We included studies from all levels of health care in low- and middle-income countries.

DATA COLLECTION AND ANALYSIS

One review author extracted data and assessed study quality, and another review author checked the data. We synthesised data using the best fit framework synthesis approach and assessed confidence in the evidence using the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach. We used a matrix approach to explore whether the factors identified by health workers in our synthesis as important for providing maternity care were reflected in the interventions evaluated in the studies in a related intervention review.

MAIN RESULTS

We included 31 studies that explored the views and experiences of different types of SBAs, including doctors, midwives, nurses, auxiliary nurses and their managers. The included studies took place in Africa, Asia, and Latin America.Our synthesis pointed to a number of factors affecting SBAs' provision of quality care. The following factors were based on evidence assessed as of moderate to high confidence. Skilled birth attendants reported that they were not always given sufficient training during their education or after they had begun clinical work. Also, inadequate staffing of facilities could increase the workloads of skilled birth attendants, make it difficult to provide supervision and result in mothers being offered poorer care. In addition, SBAs did not always believe that their salaries and benefits reflected their tasks and responsibilities and the personal risks they undertook. Together with poor living and working conditions, these issues were seen to increase stress and to negatively affect family life. Some SBAs also felt that managers lacked capacity and skills, and felt unsupported when their workplace concerns were not addressed.Possible causes of staff shortages in facilities included problems with hiring and assigning health workers to facilities where they were needed; lack of funding; poor management and bureaucratic systems; and low salaries. Skilled birth attendants and their managers suggested factors that could help recruit, keep, and motivate health workers, and improve the quality of care; these included good-quality housing, allowances for extra work, paid vacations, continuing education, appropriate assessments of their work, and rewards.Skilled birth attendants' ability to provide quality care was also limited by a lack of equipment, supplies, and drugs; blood and the infrastructure to manage blood transfusions; electricity and water supplies; and adequate space and amenities on maternity wards. These factors were seen to reduce SBAs' morale, increase their workload and infection risk, and make them less efficient in their work. A lack of transport sometimes made it difficult for SBAs to refer women on to higher levels of care. In addition, women's negative perceptions of the health system could make them reluctant to accept referral.We identified some other factors that also may have affected the quality of care, which were based on findings assessed as of low or very low confidence. Poor teamwork and lack of trust and collaboration between health workers appeared to negatively influence care. In contrast, good collaboration and teamwork appeared to increase skilled birth attendants' motivation, their decision-making abilities, and the quality of care. Skilled birth attendants' workloads and staff shortages influenced their interactions with mothers. In addition, poor communication undermined trust between skilled birth attendants and mothers.

AUTHORS' CONCLUSIONS

Many factors influence the care that SBAs are able to provide to mothers during childbirth. These include access to training and supervision; staff numbers and workloads; salaries and living conditions; and access to well-equipped, well-organised healthcare facilities with water, electricity, and transport. Other factors that may play a role include the existence of teamwork and of trust, collaboration, and communication between health workers and with mothers. Skilled birth attendants reported many problems tied to all of these factors.

Access barriers to obstetric care at health facilities in sub-Saharan Africa-a systematic review

BACKGROUND

Since 2000, the United Nations' Millennium Development Goals, which included a goal to improve maternal health by the end of 2015, has facilitated significant reductions in maternal morbidity and mortality worldwide. However, despite more focused efforts made especially by low- and middle-income countries, targets were largely unmet in sub-Saharan Africa, where women are plagued by many challenges in seeking obstetric care. The aim of this review was to synthesise literature on barriers to obstetric care at health institutions in sub-Saharan Africa.

METHODS

This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus databases were electronically searched to identify studies on barriers to health facility-based obstetric care in sub-Saharan Africa, in English, and dated between 2000 and 2015. Combinations of search terms 'obstetric care', 'access', 'barriers', 'developing countries' and 'sub-Saharan Africa' were used to locate articles. Quantitative, qualitative and mixed-methods studies were considered. A narrative synthesis approach was employed to synthesise the evidence and explore relationships between included studies.

RESULTS

One hundred and sixty articles met the inclusion criteria. Currently, obstetric care access is hindered by several demand- and supply-side barriers. The principal demand-side barriers identified were limited household resources/income, non-availability of means of transportation, indirect transport costs, a lack of information on health care services/providers, issues related to stigma and women's self-esteem/assertiveness, a lack of birth preparation, cultural beliefs/practices and ignorance about required obstetric health services. On the supply-side, the most significant barriers were cost of services, physical distance between health facilities and service users' residence, long waiting times at health facilities, poor staff knowledge and skills, poor referral practices and poor staff interpersonal relationships.

CONCLUSION

Despite similarities in obstetric care barriers across sub-Saharan Africa, country-specific strategies are required to tackle the challenges mentioned. Governments need to develop strategies to improve healthcare systems and overall socioeconomic status of women, in order to tackle supply- and demand-side access barriers to obstetric care. It is also important that strategies adopted are supported by research evidence appropriate for local conditions. Finally, more research is needed, particularly, with regard to supply-side interventions that may improve the obstetric care experience of pregnant women.

Clinical practice patterns on the use of magnesium sulphate for treatment of pre-eclampsia and eclampsia: a multi-country survey

Objective

To characterise the current clinical practice patterns regarding the use of magnesium sulphate (MgSO₄) for eclampsia prevention and treatment in a multi‐country network of health facilities and compare with international recommendations.

Design

Cross‐sectional survey.

Setting

A total of 147 health facilities in 15 countries across Africa, Latin America and Asia.

Population

Heads of obstetric departments or maternity units.

Methods

Anonymous online and paper‐based survey conducted in 2015.

Main outcome measures

Availability and use of MgSO₄; availability of a formal clinical protocol for MgSO₄ administration; and MgSO₄ dosing regimens for eclampsia prevention and treatment.

Results

Magnesium sulphate and a formal protocol for its administration were reported to be always available in 87.4% and 86.4% of all facilities, respectively. MgSO₄ was used for the treatment of mild pre‐eclampsia, severe pre‐eclampsia and eclampsia in 24.3%, 93.5% and 96.4% of all facilities, respectively. Regarding the treatment of severe pre‐eclampsia, 26.4% and 7.0% of all facilities reported using dosing regimens that were consistent with Zuspan and Pritchard regimens, respectively. Across regions, intramuscular maintenance regimens were more commonly used in the African region (45.7%) than in the Latin American (3.0%) and Asian (22.9%) regions, whereas intravenous maintenance regimens were more often used in the Latin American (94.0%) and Asian (60.0%) regions than in the African region (21.7%). Similar patterns were found for the treatment of eclampsia across regions.

Conclusions

The reported clinical use of MgSO₄ for eclampsia prevention and treatment varied widely, and was largely inconsistent with current international recommendations.

Tweetable abstract

MgSO₄ regimens for eclampsia prevention and treatment in many hospitals are inconsistent with international recommendations.

Situational analysis of facilitators and barriers to availability and utilization of magnesium sulfate for eclampsia and severe preeclampsia in the public health system in Brazil

BACKGROUND

Eclampsia is the main cause of maternal death in Brazil. Magnesium sulfate is the drug of choice for seizure prevention and control in the management of severe preeclampsia and eclampsia. Despite scientific evidence demonstrating its effectiveness and safety, there have been delays in managing hypertensive disorders, including timely access to magnesium sulfate. To conduct a general situational analysis on availability and use of magnesium sulfate for severe preeclampsia and eclampsia in the public health system.

METHOD

A situational analysis was conducted with two components: a documental analysis on information available at the official websites on the policy, regulation and availability of the medication, plus a cross sectional study with field analysis and interviews with local managers of public obstetric health services in Campinas, in the southeast of Brazil. We used the fishbone cause and effect diagram to organize study components. Interviews with managers were held during field observations using specific questionnaires.

RESULTS

There was no access to magnesium sulfate in primary care facilities, obstetric care was excluded from urgency services and clinical protocols for professional guidance on the adequate use of magnesium sulfate were lacking in the emergency mobile care service. Magnesium sulfate is currently only administered in referral maternity hospitals.

CONCLUSION

The lack of processes that promote the integration between urgency/emergency care and specialized obstetric care possibly favors the untimely use of magnesium sulfate and contributes to the high maternal morbidity/mortality rates.
