A population-based estimation of maternal mortality in Lagos State, Nigeria using the indirect sisterhood method.

BACKGROUND: Pregnancy and delivery deaths represent a risk to women, particularly those living in low- and middle-income countries (LMICs). This population-based survey was conducted to provide estimates of the maternal mortality ratio (MMR) in Lagos Nigeria. METHODS: A community-based, cross-sectional study was conducted in mapped Wards and Enumeration Areas (EA) of all Local Government Areas (LGAs) in Lagos, among 9,986 women of reproductive age (15-49 years) from April to August 2022 using a 2-stage cluster sampling technique. A semi-structured, pre-tested questionnaire adapted from nationally representative surveys was administered using REDCap by trained field assistants for data collection on socio-demographics, reproductive health, fertility, and maternal mortality. Data were analysed using SPSS and MMR was estimated using the indirect sisterhood method. Ethical approval was obtained from the Lagos State University Teaching Hospital Health Research and Ethics Committee. RESULTS: Most of the respondents (28.7%) were aged 25-29 years. Out of 546 deceased sisters reported, 120 (22%) died from maternal causes. Sisters of the deceased aged 20-24 reported almost half of the deaths (46.7%) as due to maternal causes, while those aged 45-49 reported the highest number of deceased sisters who died from other causes (90.2%). The total fertility rate (TFR) was calculated as 3.807, the Lifetime Risk (LTR) of maternal death was 0.0196 or 1-in-51, and the MMR was 430 per 100,000 [95% CI: 360-510]. CONCLUSION: Our findings show that the maternal mortality rate for Lagos remains unacceptable and has not changed significantly over time in actual terms. There is need to develop and intensify community-based intervention strategies, programs for private hospitals, monitor MMR trends, identify and contextually address barriers at all levels of maternal care.

Challenges in conducting population-based seroepidemiology survey of COVID-19 in Lagos State, Nigeria.

Population-based study is known to be a very essential type of study during and after a pandemic or epidemic, as it provides crucial information on the incidence, prevalence, and risk factors of the disease in question. There has been limited information about the challenges faced in conducting such surveys in Nigeria. In this paper, we will share our experience, and describe the challenges faced in conducting a population-based seroepidemiological study of COVID-19 in Lagos, Nigeria. Some challenges were peculiar to specific Local Government Areas (LGAs) while others were general. The challenges include general misconceptions of community members about health research, difficulties in mapping houses, planning for data collection, standardizing data collection, working in hard-to-reach communities when resources were limited as well as difficulty in collection of blood and naso-oropharyngeal swabs. Ways of overcoming these problems, lessons learnt, and recommendations are hereby discussed.

Cohort event monitoring for safety signal detection in adult individuals 18 years and above after immunisation with coronavirus disease 2019 vaccines in Nigeria.

Introduction: In Nigeria, immunisation with coronavirus disease 2019 (COVID-19) vaccines commenced in March 2021. COVISHIELD from AstraZeneca (AZ), a viral vector vaccine, was the brand administered in the first phase of vaccinations for pre-determined eligible adults 18 years and above. As more brands of COVID-19 vaccines have been introduced in Nigeria, identifying effective and safe vaccine brands is essential to pharmacovigilance and public health. The current study assessed the safety of the AZ-AZD1222 (ChAdOx1) COVID-19 vaccine in adults during the first phase of the vaccination exercise in Nigeria. Methodology: We conducted a descriptive analysis of safety data from selected vaccination sites across six states in Nigeria between June 2021 and September 2021. Respondents were monitored over 3 months for local and systemic reactions, as well as hospitalisation and mortality. Measures obtained from respondents include age, sex, pre-existing comorbidity, local and systemic reactions to vaccines, timing onset of reactions, hospitalisation and mortality. Bivariate and multivariable regression models were used to assess factors associated with vaccine reactogenicity. Results: A total of 1284 individuals were enrolled in the cohort study from the six selected states (Anambra, Borno, Edo, Katsina, Lagos and Plateau) representing the geopolitical zones of Nigeria. A total of 675 individuals or 52.6% of enrolees reported non-serious adverse effects, and only one individual or 0.08% reported a serious adverse event following immunisation in the first 7 days after vaccination. None of the enrolled participants reported adverse events requiring hospitalisation. The most common self-reported symptoms amongst vaccine recipients were tenderness at the injection site 20.9% and fever 20.3%. A majority of symptoms (55.5%) occurred on or before the 3rd day after vaccination. Multivariable logistic regression model showed that age 60 years or above (vs. 18-24 years) was significantly associated with a lower likelihood of a vaccine-related symptomatic reaction (adjusted odds ratio: 0.35; 95% confidence interval: 0.20-0.61). There was no reported mortality amongst all the enrolled and followed-up vaccine recipients. Conclusion: Our findings suggest that the safety profile of the AZ vaccine is acceptable, and the observed symptoms were mild and mostly within the first 3 days following vaccination. Vaccine recipients will benefit from counselling about potential transient reactions, and improving public awareness can potentially encourage the uptake of vaccines and reduce the spread of the COVID-19 pandemic.

Contraceptive use and fertility control in rural and urban communities of Lagos Nigeria.

Background: It is predicted that the population of sub-Saharan Africa will be thrice its size by the end of the 21st century. Our study compared patterns, incentives and disincentives for the uptake of contraceptives in rural and urban communities of Lagos, Nigeria. Materials and Methods: This is a population-based cross-sectional study on 1445 women of reproductive ages 15-49 years using a cluster sampling technique and a pre-tested, interviewer-administered electronic questionnaire in 2020. Data were analysed using the Statistical Package for the Social Sciences (SPSS) software version 26.0 and ethical approval was obtained for the study. Results: About 32.4% of the respondents were rural dwellers and 67.6% were urban residents. The overall mean age was 31.7 ± 7.8 years. In terms of pattern, slightly over half (53.3%) of all respondents had ever used family planning (FP), including modern contraceptives and slightly less than a third (30.8%) currently use FP methods in both rural and urban communities, respectively. Predominant disincentives for non-use of FP include a desire to retain fertility, lack of further need, unbearable side effects and lack of spousal support. The odds of being an urban dweller currently using a method of contraceptive method is 4.169 times higher for earners above ₦60,000, which is twice the minimum wage compared to those without income (adjusted odd's ratio: 4.169, 95% confidence interval: 1.395-12.462). Conclusion: Sustained effort is required to improve contraceptive uptake, FP service delivery and demand satisfaction for modern contraceptives to enable the achievement of demographic dividends and gains.

Public Health Surveillance for Adverse Events Following COVID-19 Vaccination in Africa.

Local, national, and international health agencies have advocated multi-pronged public health strategies to limit infections and prevent deaths. The availability of safe and effective vaccines is critical in the control of a pandemic. Several adverse events have been reported globally following reception of different vaccines, with limited or no data from Africa. This cross-sectional epidemiological study investigated adverse events following COVID-19 vaccination in Africans from April-June, 2021 using a structured online questionnaire. Out of 1200 participants recruited, a total of 80.8% (n = 969) respondents from 35 countries, including 22 African countries and 13 countries where Africans live in the diaspora, reported adverse events. Over half of the vaccinees were male (53.0%) and frontline healthcare workers (55.7%), respectively. A total of 15.6% (n = 151) reported previous exposure to SARS-CoV-2, while about one-fourth, 24.8% (n = 240), reported different underlying health conditions prior to vaccination. Fatal cases were 5.1% (n = 49), while other significant heterogenous events were reported in three categories: very common, common, and uncommon, with the latter including enlarged lymph nodes 2.4% (n = 23), menstrual disorder 0.5% (n = 5), and increased libido 0.2% (n = 2). The study provided useful data for concerned authorities and institutions to prepare plans that will address issues related to COVID-19 vaccines.

Travel of pregnant women in emergency situations to hospital and maternal mortality in Lagos, Nigeria: a retrospective cohort study.

INTRODUCTION: Prompt access to emergency obstetrical care (EmOC) reduces the risk of maternal mortality. We assessed institutional maternal mortality by distance and travel time for pregnant women with obstetrical emergencies in Lagos State, Nigeria. METHODS: We conducted a facility-based retrospective cohort study across 24 public hospitals in Lagos. Reviewing case notes of the pregnant women presenting between 1 November 2018 and 30 October 2019, we extracted socio-demographic, travel and obstetrical data. The extracted travel data were exported to Google Maps, where driving distance and travel time data were extracted. Multivariable logistic regression was conducted to determine the relative influence of distance and travel time on maternal death. FINDINGS: Of 4181 pregnant women with obstetrical emergencies, 182 (4.4%) resulted in maternal deaths. Among those who died, 60.3% travelled ≤10 km directly from home, and 61.9% arrived at the hospital ≤30 mins. The median distance and travel time to EmOC was 7.6 km (IQR 3.4-18.0) and 26 mins (IQR 12-50). For all women, travelling 10-15 km (2.53, 95% CI 1.27 to 5.03) was significantly associated with maternal death. Stratified by referral, odds remained statistically significant for those travelling 10-15 km in the non-referred group (2.48, 95% CI 1.18 to 5.23) and for travel ≥120 min (7.05, 95% CI 1.10 to 45.32). For those referred, odds became statistically significant at 25-35 km (21.40, 95% CI 1.24 to 36.72) and for journeys requiring travel time from as little as 10-29 min (184.23, 95% CI 5.14 to 608.51). Odds were also significantly higher for women travelling to hospitals in suburban (3.60, 95% CI 1.59 to 8.18) or rural (2.51, 95% CI 1.01 to 6.29) areas. CONCLUSION: Our evidence shows that distance and travel time influence maternal mortality differently for referred women and those who are not. Larger scale research that uses closer-to-reality travel time and distance estimates as we have done, rethinking of global guidelines, and bold actions addressing access gaps, including within the suburbs, will be critical in reducing maternal mortality by 2030.

Use of modern contraceptives in Lagos Nigeria during the COVID-19 pandemic.

We estimated modern contraceptive prevalence rate (mCPR) and examined predictors of modern contraceptives utilization amongst 1,445 sampled reproductive age women in Lagos (Nigeria's epicenter) during the devastating COVID-19 pandemic. Estimated mCPR was 30.8%. Women aged 20-29 years were 50% (95%CI:0.37-0.71) less likely to use modern contraceptives during the pandemic than those 30-39 years. Married and divorced women were about three (95%CI:1.37-5.25) and over three (95%CI:1.32-7.79) times more likely to use modern contraceptives compared to single women. Though mCPR has not reduced, sustained contraceptive needs assessment of sometimes obscure sub-populations is required, especially if outbreaks like COVID-19 become our 'new normal'.

Epidemiology of rheumatic and musculoskeletal diseases in a Nigerian peri-urban community: results of a cross-sectional survey using the COPCORD stage 1 model.

Introduction: There is relative neglect of rheumatic and musculoskeletal diseases (RMDs) in sub-Saharan Africa (SSA). While hospital-based reports on RMDs abound, there is a paucity of population-based reports on these conditions which are otherwise recognized to cause functional disability and reduced quality of life in the affected individuals. Thus, the objective of this study is to determine the prevalence, diagnostic types, and predictors of musculoskeletal (MSK) pain in Agbowa, a peri-urban community in Lagos, South-West Nigeria. Material and methods: This community-based survey utilized the World Health Organisation/International League of Association of Rheumatology Community Oriented Programme for the Control of Rheumatic Diseases (WHO/ILAR COPCORD) stage 1 model. All respondents had their profiles documented via modified COPCORD questionnaires. Pain intensity and functional disability were assessed by the Numerical Rating Scale (NRS) and Health Assessment Questionnaires Disability Index (HAQ-DI) respectively. The rheumatic and musculoskeletal diseases were classified using relevant validated criteria. Data obtained were analysed using SPSS Version 21. Results: There were 3056 respondents who were predominantly female (59.2%). The period prevalence of MSK pain among the 3056 respondents was 58% (n = 1,773). There were significantly more females with MSK pain than males (62.8% vs. 37.2%, p = 0.001). Overall, 380 (12.4%) subjects had clinically diagnosed RMDs. The common RMDs in decreasing order were osteoarthritis (n = 185, 6.1%), chronic low back pain (n = 95, 3.1%) and soft tissue rheumatism (n = 52, 1.7%). The bivariate analysis showed that female sex, family history of MSK conditions, history of previous trauma, and some comorbidities were significantly associated with MSK pain. The median HAQ-DI was 0.6 (IQR 0.1-1.8) with significant disability (HAQ-DI ≥ 1) in 39.5% of the subjects. Conclusions: The burden and impacts of these conditions are considerable. Thus, the government needs to devise programmes and policies to limit the effects of RMDs in such communities.

Electronic cigarette use among adolescents and young adults in Nigeria: Prevalence, associated factors and patterns of use.

BACKGROUND: Electronic cigarettes (e-cigarettes) have emerged in the Nigerian market, and if used without supervision, may have damaging effects on the physical and mental health of users. Therefore, there is a need to determine the patterns of use, especially among adolescents and young adults. This study aims to assess the prevalence and factors associated with electronic cigarette use, as well as the relationship between their use and anxiety among adolescents and young adults in Lagos, Nigeria. METHOD: An online cross-sectional study among participants aged between 15-35 years. The survey had three sections: sociodemographic information, the pattern of e-cigarette use, and a 7-item Generalized Anxiety Disorder (GAD-7) scale. Bivariate and multivariable logistic regression analysis was used to identify factors associated with e-cigarette use. P-values <0.05 were considered significant. Statistical analysis was done using STATA-15.0 software. RESULTS: Data from a total of 949 respondents was analysed. Participants had a mean age of 23.36 years (±3.97) and were predominantly female (55.64%). The prevalence of e-cigarette ever-use was 7.9% (95% CI: 5.8,10.0). Older age and being male were independently associated with higher odds of e-cigarette use. After adjusting for age and sex, alcohol use (p<0.001), friend's use (p<0.001), and other tobacco product or substance use (p:0.05) remained significantly associated with higher odds of e-cigarette use. There was no association between anxiety levels and e-cigarette use. CONCLUSION: These findings suggest a higher likelihood of e-cigarette use among alcohol consumers, poly-tobacco or substance users and individuals with friends who use e-cigarettes. Health providers and policy makers in Nigeria might consider preventive measures aimed at young adults with the identified risk factors, as well as close monitoring of trends in e-cigarette use in the coming years.

Association between anxiety, alcohol, poly-tobacco use and waterpipe smoking: A cross-sectional study in Lagos, Nigeria.

BACKGROUND: Waterpipe smoking (WPS) has been reported to have a wide range of damaging health effects on pulmonary and cardiovascular systems. Studies suggest that waterpipe tobacco smoking is associated with reduced harm perceptions, mental health problems and the use of psychoactive substances. We investigate the patterns of use and the association of WPS with anxiety, poly-tobacco and alcohol use in Lagos, Nigeria. MATERIALS AND METHODS: A cross-sectional study design was used to assess the data from 818 adolescents and adults in Lagos State, Nigeria. An online questionnaire obtained demographic information, waterpipe, e-cigarette, alcohol and other tobacco product use from respondents. Anxiety was assessed using the validated Generalised Anxiety Disorder 7-point scale. Bivariate and multivariate logistic regression analysis was used to identify the factors associated with waterpipe ever-use. P < 0.05 was considered statistically significant. RESULTS: The mean (standard deviation) age of respondents was 23.43 (±3.96), over half were female (55.2%) and a majority had a college diploma or more (88.59%). Among study participants, 18.58% reported waterpipe ever-use. Among ever waterpipe users, 17.33% reported current use (past 30-days), with a majority having smoked waterpipe in a bar or pub. Alcohol use (P < 0.001), e-cigarette ever-use (P: 0.010) and poly-tobacco ever-use (P: 0.030) were significantly associated with higher odds of waterpipe use in the multivariate regression model. Further, there was a lower likelihood of waterpipe ever-use in the bivariate regression model among respondents with mild and moderate to severe anxiety levels than those with normal anxiety levels (P: 0.030); however, this association was no longer significant in the adjusted model. CONCLUSIONS: Our findings suggest a relatively high prevalence of WPS in Lagos, Nigeria. Concurrent alcohol consumption, e-cigarette and poly-tobacco use are associated with WPS, and most waterpipe smokers have normal anxiety levels. The Nigerian Government should consider surveillance measures for WPS and a more comprehensive smoke-free policy.

'Long COVID': persistent COVID-19 symptoms in survivors managed in Lagos State, Nigeria.

BACKGROUND: Coronavirus disease once thought to be a respiratory infection is now recognised as a multi-system disease affecting the respiratory, cardiovascular, gastrointestinal, neurological, immune, and hematopoietic systems. An emerging body of evidence suggests the persistence of COVID-19 symptoms of varying patterns among some survivors. This study aimed to describe persistent symptoms in COVID-19 survivors and investigate possible risk factors for these persistent symptoms. METHODS: The study used a retrospective study design. The study population comprised of discharged COVID-19 patients. Demographic information, days since discharge, comorbidities, and persistent COVID-19 like symptoms were assessed in patients attending the COVID-19 outpatient clinic in Lagos State. Statistical analysis was done using STATA 15.0 software (StataCorp Texas) with significance placed at p-value < 0.05. RESULTS: A total of 274 patients were enrolled in the study. A majority were within the age group > 35 to ≤49 years (38.3%), and male (66.1%). More than one-third (40.9%) had persistent COVID-19 symptoms after discharge, and 19.7% had more than three persistent COVID-like symptoms. The most persistent COVID-like symptoms experienced were easy fatigability (12.8%), headaches (12.8%), and chest pain (9.8%). Symptomatic COVID-19 disease with moderate severity compared to mild severity was a predictor of persistent COVID-like symptoms after discharge (p < 0.05). CONCLUSION: Findings from this study suggests that patients who recovered from COVID-19 disease may still experience COVID-19 like symptoms, particularly fatigue and headaches. Therefore, careful monitoring should be in place after discharge to help mitigate the effects of these symptoms and improve the quality of life of COVID-19 survivors.

Predictors of COVID-19 Information Sources and Their Perceived Accuracy in Nigeria: Online Cross-sectional Study.

BACKGROUND: Effective communication is critical for mitigating the public health risks associated with the COVID-19 pandemic. OBJECTIVE: This study assesses the source(s) of COVID-19 information among people in Nigeria, as well as the predictors and the perceived accuracy of information from these sources. METHODS: We conducted an online survey of consenting adults residing in Nigeria between April and May 2020 during the lockdown and first wave of COVID-19. The major sources of information about COVID-19 were distilled from 7 potential sources (family and friends, places of worship, health care providers, internet, workplace, traditional media, and public posters/banners). An open-ended question was asked to explore how respondents determined accuracy of information. Statistical analysis was conducted using STATA 15.0 software (StataCorp Texas) with significance placed at P<.05. Approval to conduct this study was obtained from the Lagos State University Teaching Hospital Health Research Ethics Committee. RESULTS: A total of 719 respondents completed the survey. Most respondents (n=642, 89.3%) obtained COVID-19-related information from the internet. The majority (n=617, 85.8%) considered their source(s) of information to be accurate, and 32.6% (n=234) depended on only 1 out of the 7 potential sources of COVID-19 information. Respondents earning a monthly income between NGN 70,000-120,000 had lower odds of obtaining COVID-19 information from the internet compared to respondents earning less than NGN 20,000 (odds ratio [OR] 0.49, 95% CI 0.24-0.98). In addition, a significant proportion of respondents sought accurate information from recognized health organizations, such as the Nigeria Centre for Disease Control and the World Health Organization. CONCLUSIONS: The internet was the most common source of COVID-19 information, and the population sampled had a relatively high level of perceived accuracy for the COVID-19 information received. Effective communication requires dissemination of information via credible communication channels, as identified from this study. This can be potentially beneficial for risk communication to control the pandemic.

Clinical characteristics, predictors of symptomatic coronavirus disease 2019 and duration of hospitalisation in a cohort of 632 Patients in Lagos State, Nigeria.

OBJECTIVE: The clinical spectrum of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is still evolving. This study describes the clinical characteristics and investigates factors that predict symptomatic presentation and duration of hospitalisation in a cohort of coronavirus disease 2019 (COVID-19) patients managed in Lagos, Nigeria. METHODOLOGY: This was a retrospective assessment of patients hospitalised with COVID-19 disease in six dedicated facilities in Lagos, Nigeria, between April 1st and May 31st 2020. Participants were individuals with laboratory-confirmed SARS-CoV-2 infection. The outcome measures were presence of symptoms and duration of hospitalisation. Demographic and comorbidity data were also obtained. Statistical analysis was done using STATA 15.0 software, with P < 0.05 being considered statistically significant. RESULTS: A total of 632 cases were analysed. The median age was 40 years (IQR: 30.5-49); male patients accounted for 60.1%. About 63% of patients were asymptomatic at presentation. Among the symptomatic, the most common symptoms were cough (47.4%) and fever (39.7%). The most common comorbidities were hypertension (16.8%) and diabetes (5.2%). The median duration of hospitalisation was 10 days (IQR: 8-14). Comorbidities increased the odds of presenting with symptoms 1.6-fold (P = 0.025) for one comorbidity and 3.2-fold (P = 0.005) for ≥2 comorbidities. Individuals aged ≥50 years were twice as likely to be hospitalised for more than 14 days compared to individuals aged <50 years (P = 0.016). CONCLUSION: Most individuals had no symptoms with comorbidities increasing the likelihood of symptoms. Older age was associated with longer duration of hospitalisation. Age and comorbidities should be used for COVID-19 triaging for efficient resource allocation.

Nuances of reproductive decisions by women in a rural community of Lagos, Nigeria.

INTRODUCTION: inadequate utilization of maternal health services due to limited reproductive decision-making capacity could be contributory to high maternal mortality in developing countries. This study sought to assess nuances of reproductive decisions by women in a rural community of Lagos, Nigeria. METHODS: this descriptive, cross-sectional house to house survey was part of a study conducted in April 2015 on females selected from 298 households chosen based on geographical clusters by simple random sampling. The study instrument was adapted from a USAID-funded project and was interviewer-administered. Data entry and analysis were performed with the aid of Epi-info™ 7.0.8.3 statistical software and ethical approval was obtained for the study. RESULTS: spousal age difference was less than 10 years for about half (51.3%) of the respondents. The majority (91.6%) of the respondents had received antenatal care during pregnancy and jointly decided with their spouses on place of care. The most commonly used contraceptives were the pills (23.5%), injectables (16.8%) and condoms (13.8%). Spousal disapproval regarding the use of family planning was almost nil at 1%. Employment status as a socio-economic factor did not significantly affect respondents´ involvement in decision-making. However, there were statistically significant associations between spousal age differences and some indicators of autonomy such as respondents´ involvement in health care decisions and the determinant on choice of antenatal care provider. CONCLUSION: women´s reproductive independence and involvement in health decisions could result in reduction of maternal ill-health and mortality whilst promoting higher male involvement and better maternal health.

Hypertension and Sudden Unexpected Deaths: An Autopsy Study of Four Hundred and Seventy-Seven Brought-in-Dead in a Tertiary Health Center.

INTRODUCTION: Hypertension is an important and major public health concern globally. One of the major causes of sudden death worldwide is hypertension. This study is to present the morphological pattern of deaths at autopsy of those patients who were brought-in-dead (BID) and who had hypertensive heart disease (HHD) as the underlying illness. MATERIALS AND METHODS: This is a 6-year retrospective autopsy study of BID patients as a result of HHD seen at our department between January 1, 2010, and December 31, 2015. The autopsy findings and data retrieved were analyzed using IBM Statistical Package for Social Sciences version 20. Test for statistical significance was set at P < 0.05. RESULTS: A total of 477 deaths (44%) as a result of HHD were recorded out of the 1016 BID during the period under study. The age ranged from 21 to 92 years with a mean age of 52 ± 14.0 years and a male to female ratio of 1.8:1. The 5th decade of life was the most common age group encountered. The most common cause of death was acute left ventricular failure (67.8%), and myocardial infarction was the least common (1.7%). CONCLUSIONS: Acute left ventricular heart failure was the most common cause of sudden death as a result of hypertension and was followed by intracerebral hemorrhage. In the female gender, sudden deaths were most common in the 6th decade and in the male gender most sudden deaths were seen in the 5th decade.

Assessing geographical distribution and accessibility of emergency obstetric care in sub-Saharan Africa: a systematic review.

METHODS: Two reviewers systematically searched multiple databases for articles published between January 2009 and June 2018. Both screened and selected studies based on the set inclusion criteria. Following quality assessments, data on study characteristics, process of data collection and analysis and findings reported were extracted. Extracted data were synthesised and presented in tables and charts. Narrative synthesis was used to summarise reported findings. RESULTS: 15 studies met the inclusion criteria, with varying assessed quality: high (7 studies), medium (4 studies) and low (4 studies). 8 studies were conducted at a national level while 7 were sub-national. 8 studies focused on assessing Indicator 2, while the others assessed multiple EmOC indicators. Only about half of the studies presented details of analysis for assessing geographical distribution, provided a map and interpreted their findings. Similarly, half of the studies used geographic information systems (GIS) for analyses. Of these, GIS was used to map EmOC facilities or relate facility numbers to 500 000 population (3), estimate straight-line distances between facilities and residences of women (2) and model travel scenarios (3). EmOC facilities in SSA are concentrated in capitals, central and urban areas and at least a third of women in the region cannot reach their nearest EmOC facility within the recommended two-hour time-frame. CONCLUSIONS: There is a limited number of studies that have assessed EmOC geographical distribution in SSA. When available, completeness and quality of analysis are questionable. Comprehensive assessments need to maximise recent advancements in mobile and GIS open-source technology to provide more realistic representation of EmOC access for service planners and policy-makers.

Multi-stakeholder perspectives on access, availability and utilization of emergency obstetric care services in Lagos, Nigeria: A mixed-methods study.

Globally, Nigeria is the second most unsafe country to be pregnant, with Lagos, its economic nerve center having disproportionately higher maternal deaths than the national average. Emergency obstetric care (EmOC) is effective in reducing pregnancyrelated morbidities and mortalities. This mixed-methods study quantitatively assessed women's satisfaction with EmOC received and qualitatively engaged multiple key stakeholders to better understand issues around EmOC access, availability and utilization in Lagos. Qualitative interviews revealed that regarding access, while government opined that EmOC facilities have been strategically built across Lagos, women flagged issues with difficulty in access, compounded by perceived high EmOC cost. For availability, though health workers were judged competent, they appeared insufficient, overworked and felt poorly remunerated. Infrastructure was considered inadequate and paucity of blood and blood products remained commonplace. Although pregnant women positively rated the clinical aspects of care, as confirmed by the survey, satisfaction gaps remained in the areas of service delivery, care organization and responsiveness. These areas of discordance offer insight to opportunities for improvements, which would ensure that every woman can access and use quality EmOC that is sufficiently available.

Opinion of women on emergency obstetric care provided in public facilities in Lagos, Nigeria: A qualitative study.

Limited attention has been given to opinions of women receiving emergency obstetric care (EmOC) in developing countries. We organized focus groups with 39 women who received this care from Lagos public facilities. Availability of competent personnel and equipment were two positive opinions highlighted. Contrarily, women expressed concerns regarding the seeming unresponsiveness of the service to nonmedical aspects of care, associated stress of service utilization, and high treatment costs. There is a need to leverage the positive perception of women regarding the available technical resources while improving institutional care components like administrative processes, basic amenities, and costs toward increasing utilization and preventing complications.

A malariometric survey of under-fives residing in indoor residual spraying-implementing and non-implementing communities of Lagos, Nigeria.

BACKGROUND: Indoor residual spraying (IRS) is used as part of the integrated vector management strategy for the control of malaria in Lagos, Nigeria. The purpose of this study was to compare the malariometric indices of children under 5 years old living in IRS-implementing and non-IRS-implementing communities of Lagos, Nigeria. METHODS: The study was a community-based, comparative, cross-sectional study of 480 children under five recruited using a multi-stage sampling method. Data on each child were collected using a household questionnaire administered to the consenting care-giver of each selected child. Each child underwent a comprehensive physical examination. On-the-spot malaria rapid diagnostic testing and haemoglobin estimation to assess parasitaemia and anaemia, respectively, were also carried out. Risk factors for parasitaemia and anaemia were identified using multivariate logistic regression. RESULTS: A total of 238 children were studied in the IRS-implementing group while 242 children were studied in the non-IRS-implementing group. The IRS -implementing community had a lower level of parasitaemia (1.3 %) compared to the non-IRS-implementing community (5.8 %) (p < 0.001). There was no significant difference in anaemia, spleen rate and fever in the IRS-implementing group (10.9, 9.7 and 5 %) and the non-IRS-implementing group (9.9, 8.8 and 8.7 %), respectively. Residing in an IRS-implementing community was associated with lower odds of parasitaemia (OR 0.17, p < 0.01). Sleeping under a bed net was the only factor associated with anaemia (p < 0.01). CONCLUSION: IRS has led to a reduction in the level of parasitaemia in the under-fives in the study areas.
