Estimating geographic access to healthcare facilities in Sub-Saharan Africa by Degree of Urbanisation.

ABSTRACT: Measuring rates of coverage and spatial access to healthcare services is essential to inform policies for development. These rates tend to reflect the urban-rural divide, typically with urban areas experiencing higher accessibility than rural ones. Especially in Sub-Saharan Africa (SSA), a region experiencing high disease burden amid fast urbanisation and population growth. However, such assessment has been hindered by a lack of updated and comparable geospatial data on urbanisation and health facilities. In this study, we apply the UN-endorsed Degree of Urbanisation (DoU or DEGURBA) method to investigate how geographic access to healthcare facilities varies across the urban-rural continuum in SSA as a whole and in each country, for circa 2020. Results show that geographic access is overall highest in cities and peri-urban areas, where more than 95% of inhabitants live within 30 min from the nearest HCF, with this share decreasing to 80-90% in towns. This share is lowest in villages and dispersed rural areas (65%), with about 10-15% of population more than 3 h away from any health post. Challenges in geographic access seem mostly determined by high travel impedance, since overall spatial densities of HCF are comparable to European levels.

Project description:BackgroundSince 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.MethodsThis 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.ResultsOne 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.ConclusionDespite 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.Systematic review registrationPROSPERO 2014 CRD42014015549.

Project description:Sub-Saharan Africa represents 69% of the total number of individuals living with HIV infection worldwide and 72% of AIDS deaths globally. Pulmonary infection is a common and frequently fatal complication, though little is known regarding the lower airway microbiome composition of this population. Our objectives were to characterize the lower airway microbiome of Ugandan HIV-infected patients with pneumonia, to determine relationships with demographic, clinical, immunological, and microbiological variables and to compare the composition and predicted metagenome of these communities to a comparable cohort of patients in the US (San Francisco). Bronchoalveolar lavage samples from a cohort of 60 Ugandan HIV-infected patients with acute pneumonia were collected. Amplified 16S ribosomal RNA was profiled and aforementioned relationships examined. Ugandan airway microbiome composition and predicted metagenomic function were compared to US HIV-infected pneumonia patients. Among the most common bacterial pulmonary pathogens, Pseudomonas aeruginosa was most prevalent in the Ugandan cohort. Patients with a richer and more diverse airway microbiome exhibited lower bacterial burden, enrichment of members of the Lachnospiraceae and sulfur-reducing bacteria and reduced expression of TNF-alpha and matrix metalloproteinase-9. Compared to San Franciscan patients, Ugandan airway microbiome were significantly richer, and compositionally distinct with predicted metagenomes that encoded a multitude of distinct pathogenic pathways e.g secretion systems. Ugandan pneumonia-associated airway microbiome is compositionally and functionally distinct from those detected in comparable patients in developed countries, a feature which may contribute to adverse outcomes in this population. Please note that the data from the comparable cohort of patients in the USUS data was published as supplemental material of PMID: 22760045 but not submitted to GEO The 'patient_info.txt' contains 12 clinical, 7 immunological and 3 microbiological variables for each patient.

Project description:IntroductionSub-Saharan Africa (SSA) region harbours the highest burden of HIV infections in the world. Agricultural work has been reported as one of the occupations with a high prevalence of HIV. Farm workers generally have poor access to health services, which prevents them from receiving proper HIV prevention and care. Furthermore, poor policies and policy implementation, and lack of workplace programmes increases farm workers' vulnerability to HIV infection. Thus, the aim of this study is to conduct a systematic review to assess HIV prevention and treatment services and national policies governing access to healthcare services by farm workers in SSA.Methods and analysisOur systematic review will include studies published from January 1990 to December 2021 within SSA countries. We will use a sensitive search strategy for electronic bibliographic databases and grey literature sources. Databases will include PubMed, CINAHL, Cochrane library, African Index Medicus and Scopus. The main outcomes to be reported will be HIV policy for farmworkers, availability of HIV prevention service(s), availability of treatment and support to farmworkers who are living with HIV, presence of referral structures for farmworkers through the health system and follow-up services for farmworkers who are on antiretroviral therapy. We will synthesise the main characteristics of included studies and use summary measures to describe study characteristics. In a situation where data are not sufficiently homogeneous to perform a quantitative synthesis, we will conduct a narrative synthesis. We will explore themes and relationships between included studies for qualitative data.Ethics and disseminationThe study will use publicly available data and ethics exemption has been obtained from Human Research Ethics Committees, Faculty of Medicine & Health Sciences, Stellenbosch University. The results of this study will be disseminated through peer-reviewed journals, conference presentations and seminars.Prospero registration numberCRD42021277528.

Project description:BACKGROUND:Nearly 15% of all pregnancies end in fatal perinatal obstetric complications including bleeding, infections, hypertension, obstructed labor, and complications of abortion. Between 1990 and 2015, an estimated 10.7 million women died due to obstetric complications. Almost all of these deaths (99%) happened in developing countries, and 66% of maternal deaths were attributed to sub-Saharan Africa. The majority of cases of maternal mortalities can be prevented through provision of evidence-based potentially life-saving signal functions of emergency obstetric care. However, different factors can hinder women's ability to access and use emergency obstetric services in sub-Saharan Africa. Therefore, the aim of this review is to synthesize current evidence on barriers to accessing and utilizing emergency obstetric care in sub-Saharan African. Decision-makers and policy formulators will use evidence generated from this review in improving maternal healthcare particularly the emergency obstetric care. METHODS:Electronic databases including MEDLINE, CINAHL, Embase, and Maternity and Infant Care will be searched for studies using predefined search terms. Articles published in English language between 2010 and 2017 with quantitative and qualitative design will be included. The identified papers will be assessed for meeting eligibility criteria. First, the articles will be screened by examining their titles and abstracts. Then, two reviewers will review the full text of the selected articles independently. Two reviewers using a standard data extraction format will undertake data extraction from the retained studies. The quality of the included papers will be assessed using the mixed methods appraisal tool. Results from the eligible studies will be qualitatively synthesized using the narrative synthesis approach and reported using the three delays model. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist will be employed to present the findings. DISCUSSION:This systematic review will present a detailed synthesis of the evidence for barriers to access and utilization of emergency obstetric care in sub-Saharan Africa over the last 7 years. This systematic review is expected to provide clear information that can help in designing maternal health policy and interventions particularly in emergency obstetric care in sub-Saharan Africa where maternal mortality remains high.

Project description:BackgroundNearly 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.MethodsArticles 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.ResultThe 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.ConclusionsA 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.Systematic review registrationPROSPERO CRD42017074102.
