Trend and Causes of Maternal Mortality in a Nigerian Tertiary Hospital: A 5-year Retrospective Study (2010-2014) at the University of Calabar Teaching Hospital, Calabar, Nigeria

Causes of infant and under-five (under-5) morbidity and mortality among hospitalized patients in Southern Nigeria: A hospital based study

Background

Rate and pattern of under-five mortality is a reflection of a society's healthcare system and quality of life. This study is aimed at reviewing the causes of infants and under-five morbidity and mortality in Calabar, Southern Nigeria.

Methods

This study used retrospective descriptive cross-sectional design. We did a retrospective collation of data on under-five morbidity and mortality from 2012 to 2017 of under-five patients admitted or died while in admission in University of Calabar Teaching Hospital. The causes of morbidity and mortality were reported based on International Classification of Diseases 10 (ICD-10). The morbidity, mortality and fatality rates were computed.

Results

A total of 11,416 under-five admissions and 391 deaths were recorded within the study period giving a fatality rate of 3.4%. Age 1-4 years category represented 50.5% of the admissions while infants (<1 year) constitute majority of the deaths (64.7%). There were 5652 infant admissions and 253 infant deaths giving fatality rate of 4.5% within the study period. Males constituted majority (55.8%) of under-five morbidity whereas females constituted majority (51.2%) of the deaths. Conditions originating from perinatal period; and infectious and parasitic diseases were the leading broad cause of under-five mortality. Specific disease analysis showed sepsis/septicemia; congenital infectious and parasitic diseases; slow fetal growth, malnutrition and short gestation as the chief causes of both infant and under-five mortality.

Conclusion

The leading causes of under-five deaths in the studied population are amenable. Improved healthcare and antenatal will be of immense benefit.

Implementing health worker training on sepsis in South Eastern Nigeria using innovative digital strategies: an interventional study

Background

Sepsis is a leading cause of morbidity and mortality especially in low- and middle-income countries such as Nigeria. Training of health workers using digital platforms may improve knowledge and lead to better patient outcomes.

Objectives

To assess the effectiveness of a digital health educational module on sepsis in improving the knowledge of medical doctors in Cross River State Nigeria on the diagnosis and management of patients presenting with sepsis.

Design

Quasi-experimental analytical study.

Methods

We developed and deployed a sepsis module through an innovative application (Sepsis tutorial app) to doctors in Calabar, Nigeria. We assessed quantitative pre- and post-intervention knowledge scores for those completing the tutorial on sepsis between both assessments. A user satisfaction survey evaluated the content of the tutorial and the usability of the app.

Results

One hundred and two doctors completed the course. There were more males than females (58.8% versus 41.2%). Over half (52%) were junior doctors, a minority were general practitioners and house officers (3% and 5%, respectively), and 72.6% had practiced for periods ranging from 1 to 15 years post-qualification. Gender and age appeared to have no significant association with pre- and post-test scores. The oldest age group (61-70) had the lowest mean pre- and post-test scores, while general practitioners had higher mean pre- and post-test scores than other cadres. The majority (95%) of participants recorded higher post-test than pre-test scores with a significant overall increase in mean scores (25.5 ± 14.7%, p < 0.0001). Participants were satisfied with the content and multimodal delivery of the material and found the app usable.

Conclusion

Digital training using context-responsive platforms is feasible and may be used to close the critical knowledge gap required to respond effectively to medical emergencies such as sepsis in low- to middle-income settings.

Texting for life: a mobile phone application to connect pregnant women with emergency transport and obstetric care in rural Nigeria

BACKGROUND

Difficulty in transportation to access skilled providers has been cited repeatedly as a major barrier to utilization of emergency obstetric care in Nigeria.

OBJECTIVE

The objective of this paper is to describe the design, implementation, and outcomes of a mobile phone technology aimed at rapidly reaching rural Nigerian women who experience pregnancy complications with emergency transportation and access to providers.

METHOD

The project was implemented in 20 communities in two predominantly rural Local Government Areas (LGAs) of Edo State, in southern Nigeria, as part of a larger implementation project aimed at improving the access of rural women to skilled pregnancy care. The digital health innovation named Text4Life, allowed women to send a brief message from their mobile phone to a server linked to Primary Health Care (PHC) facilities and to access pre-registered transport owners. Pregnant women were registered and taught to text short messages to a server from their mobile phones or those of a friend or relative when they experience complications.

RESULTS

Over 18 months, 56 women out of 1620 registered women (3.5%) texted the server requesting emergency transportation. Of this number, 51 were successfully transported to the PHC facilities, 46 were successfully treated at the PHC, and five were referred to higher-level care facilities. No maternal deaths occurred during the period, while four perinatal deaths were recorded.

CONCLUSION

We conclude that a rapid short message sent from a mobile phone to a central server and connected to transport providers and health facility managers is effective in increasing the access of pregnant women to skilled emergency obstetric services in rural Nigeria.

Predictors and causes of in-hospital maternal deaths within 120 h of admission at a tertiary hospital in South-Western, Nigeria: A retrospective cohort study

Background

An efficient, comprehensive emergency obstetrics care (CEMOC) can considerably reduce the burden of maternal mortality (MM) in Nigeria. Information about the risk of maternal death within 120 h of admission can reflect the quality of CEMOC offered.

Aim

This study aims to determine the predictors and causes of maternal death within 120 h of admission at the Lagos University Teaching Hospital, LUTH, Lagos South-Western, Nigeria.

Methods

We conducted a retrospective cohort study amongst consecutive maternal deaths at a hospital in South-Western Nigeria, from 1 January 2007 to 31 December 2017, using data from patients' medical records. We compared participants that died within 120 h to participants that survived beyond 120 h. Survival life table analysis, Kaplan-Meier plots and multivariable Cox proportional hazard regression were conducted to evaluate the factors affecting survival within 120 h of admission. Stata version 16 statistical software (StatCorp USA) was used for analysis.

Results

Of the 430 maternal deaths, 326 had complete records. The mean age of the deceased was 30.7± (5.9) years and median time to death was 24 (5-96) h. Two hundred and sixty-eight (82.2%) women out of 326 died within 120 h of admission. Almost all maternal deaths from uterine rupture (95.2%) and most deaths from obstetric haemorrhage (87.3%), induced miscarriage (88.9%), sepsis (82.9%) and hypertensive disorders of pregnancy (77.9%) occurred within 120 h of admission. Admission to the intensive care unit (P = 0.007), cadre of admitting doctor (P < 0.001), cause of death (P = 0.036) and mode of delivery (P = 0.012) were independent predictors of hazard of death within 120 h.

Conclusion

The majority (82.2%) of maternal deaths occurred within 120 h of admission. Investment in the prevention and acute management of uterine rupture, obstetric haemorrhage, sepsis and hypertensive disorders of pregnancy can help to reduce MM within 120 h in our environment.

Intimate partner violence and the spatial pattern of maternal healthcare services utilization among parous married women in northern Nigeria

The low uptake of maternal healthcare services (MHS) in Nigeria is implicated in the country’s poor maternal health outcomes. In northern Nigeria where these outcomes are poorest, not much is known about the contribution of violence within unions on married women’s uptake of MHS. Using data on antenatal care (ANC) utilisation and place of delivery, and their sociodemographic confounders from the Nigerian Demographic and Health Survey, this study investigates this relationship. Results of univariate, bivariate and multivariate analyses show that 46.4% and 22.1% of the women had at least four ANC sessions and had health facility delivery respectively. At the subregional level however, the North-Central zone had the highest utilisation rates while the North-West zone had the lowest. The prevalence of intimate partner violence (IPV) ranged from 8.2% (sexual violence) to 16.7% (physical violence) and 35.8% (emotional violence). Subregional analysis of IPV shows that the North-West zone had the lowest prevalence rates. Contrary to some literature evidence, women who experienced IPV in the study area had higher odds of utilising MHS (P < 0.001). When the sociodemographic characteristics of the women were adjusted for, the relationship became statistically insignificant however. The association between the women’s socioeconomic characteristics and their MHS uptake suggests that attention be paid to the wealth and educational status of the population because of their propensity for sustaining the higher uptake recorded. The role of religion in the outcomes further suggests that it be used as a tool to promote the uptake of MHS in the region.

Trends and causes of maternal death at the Lagos University teaching hospital, Lagos, Nigeria (2007-2019)

Background

Nigeria has one of the worst global maternal mortality ratios (MMR). Institutional audit is invaluable in providing useful information for formulating preventive interventions.

Objective

To evaluate the trends, causes and socio-demographic characteristics of maternal mortality at a tertiary institution in South-western Nigeria over a period of 13 years (2007–2019).

Methodology

Cross sectional and temporal trend analysis of maternal deaths were conducted using chart reviews from 2007 to 2019. Socio-biological characteristics, booking status and ranking of clinical causes of maternal deaths were derived from patients’ chart review (2007–2019). Bivariate analysis and Annual percent change (APC) of the observed trends was respectively conducted using Stata version 17 and Joinpoint version 4.5.0.1 software respectively.

Results

In the period 2007–2019, the mean age at maternal death was 30.8 ± 5.9 years and 88.8% of mortalities occurred among the “unbooked” women. The leading causes of direct maternal mortality were Hypertension (27.0%), Sepsis (20.6%) and haemorrhage (18.7%), while anaemia in pregnancy (3.2%), Human Immunodeficiency Virus (3.2%) and Sickle Cell Disease (2.4%) were the leading indirect causes of maternal mortality Joinpoint estimates showed a statistically significant increase in MMR of about 3.4% per annum from 2211 per 100,000 live births in 2007 to 3555.6 per 100,000 live births in 2019 (APC: +3.4%, P-value < 0.001).

Conclusion

Contrary to some other reports, there was an increase in the institutional MMR between 2007 and 2019 even though the leading causes of death remained similar. Targeted interventions based on accurate data are urgently required in order to achieve the Sustainable Development Goal (SDG) 3.1.

Causes of maternal mortality in Sub-Saharan Africa: A systematic review of studies published from 2015 to 2020

Background

Maternal deaths remain high in Sub-Saharan Africa (SSA) and their causes of maternal death must be analysed frequently in this region to guide interventions.

Methods

We conducted a systematic review of studies published from 2015 to 2020 that reported the causes of maternal deaths in 57 SSA countries. The objective was to identify the leading causes of maternal deaths using the international classification of disease - 10^th revision, for maternal mortality (ICD-MM). We searched PubMed, WorldCat Discovery Libraries Worldwide (including Medline, Web of Science, LISTA and CNHAL databases), and Google Scholar databases and citations, using the search words "maternal mortality", "maternal death", "pregnancy-related death", "reproductive age mortality" and "causes" as MeSH terms or keywords. The last date of search from all databases was 21 May 2021. We included original research articles published in English and excluded articles that mentioned SSA country names without study results for those countries, studies that reported death from a single cause or assigned causes of death using computer models or incompletely broke down the causes of death. We exported, de-duplicated and screened the searches electronically in EndNote version 20. We selected the final articles by reading the titles, abstracts and full texts. Two authors searched the articles and assessed the risk of bias using a tool adapted from Montoya and others. Data from the articles were extracted onto an Excel worksheet and the deaths classified into ICD-MM groups. Proportions were calculated with 95% confidence intervals and compared for deaths attributed to each cause and ICD-MM group. We compared the results with WHO and Global Burden of Disease (GDB) estimates.

Results

We identified 38 studies that reported 11 427 maternal and four incidental deaths. Twenty-one of the third-eight studies were retrospective record reviews. The leading causes of death (proportions and 95% confidence intervals (CI)) were obstetric hemorrhage: 28.8% (95% CI = 26.5%-31.2%), hypertensive disorders in pregnancy: 22.1% (95% CI = 19.9%-24.2%), non-obstetric complications: 18.8% (95% CI = 16.4%-21.2%) and pregnancy-related infections: 11.5% (95% CI = 9.8%-13.2%). The studies reported few deaths of unknown/undetermined and incidental causes.

Conclusions

Limitations of this review were the failure to access more data from government reports, but the study results compared well with WHO and GDB estimates. Obstetric hemorrhage, hypertensive disorders in pregnancy, non-obstetric complications, and pregnancy-related infections are the leading causes of maternal deaths in SSA. However, deaths from incidental causes are likely under-reported in this region. SSA countries must continue to invest in health information systems that collect and publishes comprehensive, quality, maternal death causes data. A publicly accessible repository of data sets and government reports for causes of maternal death will be helpful in future reviews. This review received no specific funding and was not registered.

Prevalence of Factor V Leiden G1691A and Prothrombin G20210A Gene Mutation Among Pregnant Women: Experience from a Multi-Center Study in Nigeria

Introduction

Inherited thrombophilia and venous thromboembolism (VTE) have been closely linked to adverse pregnancy outcomes such as preeclampsia/eclampsia contributing to increased maternal and perinatal morbidity and mortality. There is, however, little genetic data from Africa including Nigeria that explores the prevalence of common VTE genetic risk markers such as factor V Leiden mutation (FVL G1691A) and prothrombin gene mutation (F2 G20210A) among pregnant women in Nigeria.

Purpose

To determine the prevalence and distribution of FVL G1691A and F2 G20210A in pregnant women in Lagos, Nigeria.

Patients and Methods

This hospital-based cross-sectional pilot study was conducted among pregnant women between 1 July 2019 and 31 August 2020. The genotype of interest was determined through amplification by polymerase chain reaction using G1691A of FV and prothrombin A20210G specific primers. Descriptive data were presented using Stata version 15 (Stata Corp) statistical software.

Results

Of the 400 recruited participants, 397 and 389 samples were successfully processed for FVL G1691A and F2 G20210A mutations, respectively. Three participants had FVL heterozygous mutation; thus, the prevalence of heterozygous mutation of FVL among the study participants was 0.76%, 95% CI: 0.002-0.023%, n=3/397. There was no F2 G20210A mutation detected among the study participants.

Conclusion

This study indicates that screening for factor V Leiden mutation and prothrombin gene mutation in pregnancy might not be of any clinical significance among Nigerian women. However, carrying out a genome-wide associated study is recommended to determine the true impact of these two common inherited thrombophilias in this population.

Methods used to measure maternal mortality in Sub-Saharan Africa from 1980 to 2020: A systematic literature review

BACKGROUND

Gobally, Sub-Saharan Africa (SSA) has the largest maternal mortality burden, but the region lacks accurate data.

OBJECTIVE

To review methods historically used to measure maternal mortality in SSA to inform future study methods.

SEARCH STRATEGY

We searched databases: PubMed, Medline, WorldCat and CINHAL, using keywords "maternal mortality," "pregnancy-related death," "reproductive age mortality," "ratio," "rate," and "risk," using Boolean operators "OR" and "AND" to combine the search terms.

SELECTION CRITERIA

We searched for empirical and analytical studies that: (1) measured maternal mortality levels, (2) were in SSA, (3) reported original results, and (4) were not duplicate studies. We included studies published in English since 1980.

DATA COLLECTION AND ANALYSIS

We screened the studies using titles and abstracts, reading the full text of selected studies. We analyzed the estimates and strengths, and limitations of the methods.

MAIN RESULTS

We identified 96 studies that used nine methods: demographic surveillance (n = 4), health record reviews (n = 18), confidential enquiries and maternal death surveillance and response (n = 7), prospective cohort (n = 9), reproductive age mortality survey (RAMOS) (n = 6), sisterhood method (n = 35), mixed methods (n = 4), and mathematical modeling (n = 13).

CONCLUSION

Sisterhood method studies and RAMOS studies that combined institutional records and community data produced maternal mortality ratios more comparable with WHO estimates.

Applying the WHO ICD-MM classification system to maternal deaths in a tertiary hospital in Nigeria: A retrospective analysis from 2014-2018

BACKGROUND

Addressing the problem of maternal mortality in Nigeria requires proper identification of maternal deaths and their underlying causes in order to focus evidence-based interventions to decrease mortality and avert morbidity.

OBJECTIVES

The objective of the study was to classify maternal deaths that occurred at a Nigerian teaching hospital using the WHO International Classification of Diseases Maternal mortality (ICD-MM) tool.

METHODS

This was a retrospective observational study of all maternal deaths that occurred in a tertiary Nigerian hospital from 1st January 2014 to 31st December,2018. The WHO ICD-MM classification system for maternal deaths was used to classify the type, group, and specific underlying cause of identified maternal deaths. Descriptive analysis was performed using Statistical Package for Social Sciences (SPSS). Categorical and continuous variables were summarized respectively as proportions and means (standard deviations).

RESULTS

The institutional maternal mortality ratio was 831/100,000 live births. Maternal deaths occurred mainly amongst women aged 25-34 years;30(57.7%), without formal education; 22(42.3%), married;47(90.4%), unbooked;24(46.2%) and have delivered at least twice;34(65.4%). The leading causes of maternal death were hypertensive disorders in pregnancy, childbirth, and the puerperium (36.5%), obstetric haemorrhage (30.8%), and pregnancy related infections (17.3%). Application of the WHO ICD-MM resulted in reclassification of underlying cause for 3.8% of maternal deaths. Postpartum renal failure (25.0%), postpartum coagulation defects (17.3%) and puerperal sepsis (15.4%) were the leading final causes of death. Among maternal deaths, type 1, 2, and 3 delays were seen in 30(66.7%), 22(48.9%), and 6(13.3%), respectively.

CONCLUSION

Our institutional maternal mortality ratio remains high. Hypertensive disorders during pregnancy, childbirth, and the puerperium and obstetric haemorrhage are the leading causes of maternal deaths. Implementation of evidence-based interventions both at the hospital and community levels may help in tackling the identified underlying causes of maternal mortality in Nigeria.

The Pregnancy Outcomes Among Newly Arrived Asylum-Seekers in Italy: Implications of Public Health

Background

Migration has a significant impact on overall health and pregnancy outcome. Despite the fact that growing volume of migration flows significantly engaging the public health system of European host countries, there is a lack of evidence concerning pregnancy outcomes of newly arrived asylum-seeking women.

Methods

Data about pregnant asylum seekers hosted in the Italian Reception Centers between the 1 st June 2016 and the 1st June 2018 were retrospectively collected and analysed in the present study. We examined the following pregnancy outcomes: miscarriage, self-induced abortion, voluntary pregnancy termination, live-birth; and studied potentially related socio-demographic factors.

Results

Out of the 110 pregnant women living in the reception centers, 44 (40%) had eutocic delivery, 8 (7.3%) dystocic delivery, 15 (13.6%) miscarriage, 17 (15.5%) self-induced abortion and 26 (23.6%) underwent voluntary pregnancy termination. Nigerian women were at a significantly higher risk of abortive outcomes for voluntary pregnancy termination (p < 0.001), miscarriage (p = 0.049) and self-induced abortion (p < 0.001). Being unmarried was significantly associated with voluntary pregnancy termination and self-induced abortion. Women who chose to undergo unsafe abortion did not result to have significantly lower educational levels, compared to women who preferred medical abortion.

Conclusion

This study offers first insights into pregnancy outcomes among asylum-seeking women in Italy. The country of origin and marital status seem to significantly impact on pregnancy outcome. We identified sub-groups of migrant women at increased risk of abortive outcomes, and highlight the need to improve care in order to promote migrant women’s reproductive health.

Assessing Implementation of Maternal and Perinatal Death Surveillance and Response in Rwanda

Maternal deaths remain a major public health concern in low- and middle-income countries. Implementation of maternal and perinatal deaths surveillance and response (MPDSR) is vital to reduce preventable deaths. The study aimed to assess implementation of MPDSR in Rwanda. We applied mixed methods following the six-step audit cycle for MPDSR to determine the level of implementation at 10 hospitals and three health centers. Results showed various stages of implementation of MPDSR across facilities. Maternal death audits were conducted regularly, and facilities had action plans to address modifiable factors. However, perinatal death audits were not formally done. Implementation was challenged by lack of enough motivated staff, heavy workload, lack of community engagement, no linkages with existing quality improvement efforts, no guidelines for review of stillbirths, incomplete medical records, poor classification of cause of death, and no sharing of feedback among others. Implementation of MPDSR varied from facility to facility indicating varying capacity gaps. There is need to integrate perinatal death audits with maternal death audits and ensure the process is part of other quality improvement initiatives at the facility level. More efforts are needed to support health facilities to improve implementation of MPDSR and contribute to achieving sustainable development goal (SDG) 3.

Maternal and perinatal death surveillance and response in Ethiopia: Achievements, challenges and prospects

Background

Maternal and Perinatal Death Surveillance and Response (MPDSR) was a pilot program introduced in Tigray, Ethiopia to monitor maternal and perinatal death. However; its implementation and operation is not evaluated yet. Therefore, this study aimed to assess the implementation and operational status and determinants of MPDSR using a programmatic data and stakeholders involved in the program.

Methods

Institutional based cross-sectional study was applied in public health facilities (75 health posts, 50 health centers and 16 hospitals) using both qualitative and quantitative methods. Data were entered in to Epi-info and then transferred to SPSS version 21 for analysis. All variables with a p-value of ≤ 0.25 in the bivariate analysis were included in to multivariable logistic regression model to identify the independent predictors. For the qualitative part, manual thematic content analysis was done following data familiarization (reading and re-reading of the transcripts).

Results

In this study, only 34 (45.3%) of health posts were practicing early identification and notification of maternal/perinatal death. Furthermore, only 36 (54.5%) and 35(53%) of health facilities were practiced good quality of death review and took proper action respectively following maternal/perinatal deaths. Availability of three to four number of Health Extension Workers (HEWs) (Adjusted Odds Ratio (AOR) = 6.09, 95%CI (Confidence Interval): 1.51–24.49), availability of timely Public Health Emergency Management (PHEM) reports (AOR = 4.39, 95%CI: 1.08–17.80) and participation of steering committee’s in death response (AOR = 9.19, 95%CI: 1.31–64.34) were the predictors of early identification and notification of maternal and perinatal death among health posts. Availability of trained nurse (AOR = 3.75, 95%CI: 1.08–12.99) and health facility’s head work experience (AOR = 3.70, 95%CI: 1.04–13.22) were also the predictors of quality of death review among health facilities. Furthermore; availability of at least one cluster review meeting (AOR = 4.87, 95%CI: 1.30–18.26) and uninterrupted pregnant mothers registration (AOR = 6.85, 95%CI: 1.22–38.54) were associated with proper response implementation to maternal and perinatal death. Qualitative findings highlighted that perinatal death report was so neglected. Community participation and intersectoral collaboration were among the facilitators for MPDSR implementation while limited human work force capacity and lack of maternity waiting homes were identified as some of the challenges for proper response implementation.

Conclusion

This study showed that the magnitude of: early death identification and notification, review and response implementation were low. Strengthening active surveillance with active community participation alongside with strengthening capacity building and recruitment of additional HEWs with special focus to improve the quality of health service could enhance the implementation of MPDSR in the region.

Value and Diagnostic Efficacy of Fetal Morphology Assessment Using Ultrasound in A Poor-Resource Setting

BACKGROUND

Ultrasound is operator-dependent, and its value and efficacy in fetal morphology assessment in a low-resource setting is poorly understood. We assessed the value and efficacy of fetal morphology ultrasound assessment in a Nigerian setting.

MATERIALS AND METHODS

We surveyed fetal morphology ultrasound performed across five facilities and followed-up each fetus to ascertain the outcome. Fetuses were surveyed in the second trimester (18th-22nd weeks) using the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) guideline. Clinical and surgical reports were used as references to assess the diagnostic efficacy of ultrasound in livebirths, and autopsy reports to confirm anomalies in terminated pregnancies, spontaneous abortions, intrauterine fetal deaths, and still births. We calculated sensitivity, specificity, positive and negative predictive values, Area under the curve (AUC), Youden index, likelihood ratios, and post-test probabilities.

RESULTS

In total, 6520 fetuses of women aged 15-46 years (mean = 31.7 years) were surveyed. The overall sensitivity, specificity, and AUC were 77.1 (95% CI: 68-84.6), 99.5 (95% CI: 99.3-99.7), and 88.3 (95% CI: 83.7-92.2), respectively. Other performance metrics were: positive predictive value, 72.4 (95% CI: 64.7-79.0), negative predictive value, 99.6 (95% CI: 99.5-99.7), and Youden index (77.1%). Abnormality prevalence was 1.67% (95% CI: 1.37-2.01), and the positive and negative likelihood ratios were 254 (95% CI: 107.7-221.4) and 0.23 (95% CI: 0.16-0.33), respectively. The post-test probability for positive test was 72% (95% CI: 65-79).

CONCLUSION

Fetal morphology assessment is valuable in a poor economics setting, however, the variation in the diagnostic efficacy across facilities and the limitations associated with the detection of circulatory system anomalies need to be addressed.

Hepatitis E Infection in Nigeria: A Systematic Review

BACKGROUND:

Research done globally on hepatitis E virus (HEV) infection is far fewer compared with other types of hepatitis virus infection. Little is known on the prevalence of HEV in Nigeria.

AIM:

The present study presents the prevalence of HEV infection in Nigeria from a few available research papers on HEV. The detailed statistical analysis was used to analyse the prevalence of HEV in humans and animals.

MATERIAL AND METHODS:

A literature search in Web of Science, Scopus and PubMed databases was done, and a final 7 articles were selected. Minitab 17.0 was used to perform the correlational and binary logistic analyses.

RESULTS:

Serum and faecal analysis of blood and stool samples of 1178 humans and 210 pigs (animals) were done, and the presence of anti-HEV IgG or HEV RNA in the study samples were 127 and 138 respectively. Further analysis showed the prevalence of HEV are 10.8% and 65.7% in humans and animals, respectively. Weak positive non-significant association (r = 0.327, p-value = 0.474) was obtained between the target (humans and animal) and the HEV infection (positive) groups. The application of binary logistic regression yielded an equation that can be used to predict the target group from the HEV positive humans or animals. Generally, the logistic model was not statistically significant (p-value = 0.376), and the model was able to explain 9.3% of the deviation or variability of the model. The odds ratio is OR = 1.0344 with 0.9550, 1.204 95% Confidence Interval (CI). Thus, in Nigeria, the odds of prevalence of HEV in animals are 1.0344 higher than humans.

CONCLUSION:

The risk factors obtained from the few available articles are consistent with the global epidemiology of HEV infection. Food and animal handlers and those that consume unsafe water are the key people at risk of HEV infection in Nigeria.

Maternal near-miss and death associated with abortive pregnancy outcome: a secondary analysis of the Nigeria Near-miss and Maternal Death Survey

OBJECTIVE

To investigate the prevalence of life-threatening complications related to pregnancies with abortive outcome and the associated health service events and performance in Nigerian public tertiary hospitals.

DESIGN

Secondary analysis of a nationwide cross-sectional study.

SETTING

Forty-two tertiary hospitals.

POPULATION

Women admitted for pregnancy-related complications.

METHODS

All cases of severe maternal outcomes (SMO: maternal near-miss or death) due to abortive pregnancy complications (defined as spontaneous or induced abortion, and ectopic pregnancy) were prospectively identified over 1 year using uniform identification criteria.

MAIN OUTCOME MEASURES

Prevalence of SMO, mortality index (% maternal death/SMO), case fatality rate, time until death after admission, and health service performance.

RESULTS

Of 5779 women admitted with abortive pregnancy complications, 444 (7.9%) experienced an SMO: 366 maternal near-misses and 78 maternal deaths. Intra-hospital maternal mortality ratio from complicated abortive pregnancy outcome was 85/100 000 live births. Case fatality rate was worst for abortion-related infections (19.1%). A quarter of maternal deaths occurred on the same day of admission; however, the peak time of occurrence of death was 3-7 days of admission. Women experiencing cardiovascular, renal or coagulation organ dysfunction were less likely to survive. Higher level of maternal education and closer residence to a health facility improved chance of maternal survival.

CONCLUSIONS

Abortive outcome remains a major contributor to SMO in Nigeria. Although early hospital presentation by women is critical to surviving abortive pregnancy complications, improved, appropriate, and timely management is essential to enhance maternal survival.

TWEETABLE ABSTRACT

78 maternal deaths and 366 near-misses occurred from abortions and ectopic pregnancies in 42 Nigerian referral hospitals in 1 year.
