RESUMO

Access to energy is essential for resilient health systems; however, strengthening energy infrastructure in rural health facilities remains a challenge. In 2015-19, 'Powering Healthcare' deployed solar energy solutions to off-grid rural health facilities in Ghana and Uganda to improve the availability of maternal and child health services. To explore the links between health facility electrification and service availability and use, the World Health Organization (WHO), in partnership with Dodowa Health Research Centre and Makerere University School of Public Health, carried out an implementation research study. The objectives of this study were to (1) capture changes in service availability and readiness, (2) describe changes in community satisfaction and use and (3) examine the implementation factors of sustainable electrification that affect these changes. Data were collected through interviews with over 100 key informants, focus group discussions with over 800 community members and health facility assessment checklist adapted from the WHO's Service Availability and Readiness Assessment tool. Implementation factors were organized using Normalization Process Theory constructs. The study found that access to energy is associated with increased availability of health services, access to communication technologies, appropriate storage of vaccines and medicines, enhanced health worker motivation and increased community satisfaction. Implementation factors associated with improved outcomes include stakeholder engagement activities to promote internalization, provision of materials and information to encourage participation, and establishment of relationships to support integration. Barriers to achieving outcomes are primarily health systems challenges-such as drug stockouts, lack of transportation and poor amenities-that continue to affect service availability, readiness and use, even where access to energy is available. However, through appropriate implementation and integration of sustainable electrification, strengthened energy infrastructure can be leveraged to catalyze investment in other components of functioning health systems. Improving access to energy in health facilities is, therefore, necessary but not sufficient for strengthening health systems.

RESUMO

BACKGROUND: Seasonal influenza virus is a common cause of acute lower respiratory infection (ALRI) in young children. In 2008, we estimated that 20 million influenza-virus-associated ALRI and 1 million influenza-virus-associated severe ALRI occurred in children under 5 years globally. Despite this substantial burden, only a few low-income and middle-income countries have adopted routine influenza vaccination policies for children and, where present, these have achieved only low or unknown levels of vaccine uptake. Moreover, the influenza burden might have changed due to the emergence and circulation of influenza A/H1N1pdm09. We aimed to incorporate new data to update estimates of the global number of cases, hospital admissions, and mortality from influenza-virus-associated respiratory infections in children under 5 years in 2018. METHODS: We estimated the regional and global burden of influenza-associated respiratory infections in children under 5 years from a systematic review of 100 studies published between Jan 1, 1995, and Dec 31, 2018, and a further 57 high-quality unpublished studies. We adapted the Newcastle-Ottawa Scale to assess the risk of bias. We estimated incidence and hospitalisation rates of influenza-virus-associated respiratory infections by severity, case ascertainment, region, and age. We estimated in-hospital deaths from influenza virus ALRI by combining hospital admissions and in-hospital case-fatality ratios of influenza virus ALRI. We estimated the upper bound of influenza virus-associated ALRI deaths based on the number of in-hospital deaths, US paediatric influenza-associated death data, and population-based childhood all-cause pneumonia mortality data in six sites in low-income and lower-middle-income countries. FINDINGS: In 2018, among children under 5 years globally, there were an estimated 109·5 million influenza virus episodes (uncertainty range [UR] 63·1-190·6), 10·1 million influenza-virus-associated ALRI cases (6·8-15·1); 870 000 influenza-virus-associated ALRI hospital admissions (543 000-1 415 000), 15 300 in-hospital deaths (5800-43 800), and up to 34 800 (13 200-97 200) overall influenza-virus-associated ALRI deaths. Influenza virus accounted for 7% of ALRI cases, 5% of ALRI hospital admissions, and 4% of ALRI deaths in children under 5 years. About 23% of the hospital admissions and 36% of the in-hospital deaths were in infants under 6 months. About 82% of the in-hospital deaths occurred in low-income and lower-middle-income countries. INTERPRETATION: A large proportion of the influenza-associated burden occurs among young infants and in low-income and lower middle-income countries. Our findings provide new and important evidence for maternal and paediatric influenza immunisation, and should inform future immunisation policy particularly in low-income and middle-income countries.

RESUMO

BACKGROUND: The health benefits of exclusive breastfeeding practices in both the short and long term accrue to breastfed infants, mothers, families and the society at large. Despite the evidence of these benefits and adoption of various World Health Organization (WHO) strategies on promotion of exclusive breastfeeding by Ghana, the increase in the rate of exclusive breastfeeding has been very slow in the country. This study aimed to estimate the rate and investigate socio-economic and demographic determinants of 6 months exclusive breastfeeding in two rural districts in Southern Ghana. METHODS: Pregnancy, childbirth, breastfeeding, demographic and socioeconomic information of 1870 women who were prospectively registered by the Dodowa Health and Demographic Surveillance System and gave birth between 1 January 2011 and 31 December 2013 was extracted. The proportion of 6 months exclusive breastfeeding among the study participants was estimated and the relationship between the dependent and the independent variables were explored using logistics regression model at 95% confidence level. RESULTS: The proportion of mothers who exclusive breastfed for 6 months in the study was 71.0%. Mothers aged 25-29 and 30 + years are 93 and 91% respectively more likely to practice 6 months exclusive breastfeeding compared to those aged < 20 years (OR 1.93, 95% CI 1.25, 2.99, OR 1.91, 95% CI 1.91, 3.08). The odds of artisan mothers practicing 6 months exclusive breastfeeding is 36% less likely compared to those unemployed (OR 0.64, 95% CI 0.43, 0.96). There is a higher chance that 45% of mothers with a household size of more than five members to practice exclusive breastfeeding compared to those with household size of less than six (OR 1.45, 95% CI 1.16, 1.81). Women in the fishing district were 85% less likely to practice 6 months exclusive breastfeeding compared to those in farming district (OR 0.15, 95% CI 0.12, 0.20). CONCLUSION: There is high rate of exclusive breastfeeding in the study area. Maternal age, type of occupation, household size and district of residence are determinants of 6 months exclusive breastfeeding among the study participants.

RESUMO

BACKGROUND: Pregnancy is an important period to promote healthy behaviors, prevent and identify diseases early and treat them to maximize the health and development of both the woman and her unborn child. A new World Health Organization antenatal care model recommends the initiation of antenatal care visit within the first trimester of gestation. This study sought to examine the timing of initiation of antenatal care among first-time mothers and associated factors in rural Southern Ghana. METHODS: Information on gestational age, timing of antenatal care, demographic and socioeconomic status of 1076 first-time mothers who gave birth in 2011 to 2013 in the Dodowa Health and Demographic Surveillance System were included in the study. The time of initiation of antenatal clinic attendance was calculated. The associations between dependent and independent variables were explored using logistic regression at 95% confidence interval in STATA version 14.2. RESULTS: The mean gestational age at which the first-time mothers initiated antenatal care attendance was 3 month. Maternal age, level of education and household socioeconomic status were statistically significantly associated with timing of initiation of antenatal care attendance. CONCLUSION: Although more than half of the study participants initiated ANC visit in the first trimester of pregnancy, a high proportion also started ANC attendance after the World Health Organization recommended period. Maternal age is significantly associated with timing of initiation of antenatal care visit among first-time mothers; older women were more likely to initiate antenatal care visit in the first trimester of gestation compared to the younger women.

RESUMO

BACKGROUND: In recent years, caesarean section rates continue to evoke worldwide concern because of their steady increase, lack of consensus on the appropriate caesarean section rate and the associated short- and long-term risks. This study sought to identify the rate of caesarean section and associated factors in two districts in rural southern Ghana. METHODS: Pregnancy, birth, and socio-demographic information of 4948 women who gave birth between 2011 and 2013 were obtained from the database of Dodowa Health and Demographic Surveillance System. The rate of C-section was determined and the associations between independent and dependent variables were explored using logistic regression. The analyses were done in STATA 14.2 at 95% confidence interval. RESULTS: The overall C-section rate for the study period was 6.59%. Women aged 30-34 years were more than twice likely to have C-section compared to those < 20 year (OR: 2.16, 95% CI: 1.20-3.90). However, women aged 34 years and above were more than thrice likely to undergo C-section compared to those < 20 year (OR: 3.73, 95% CI: 1.45-5.17). The odds of having C-section was 65 and 79% higher for participants with Primary and Junior High level schooling respectively (OR: 1.65, 95% CI: 1.08-2.51, OR:1.79, 95%CI: 1.19-2.70). The likelihood of having C-section delivery reduced by 60, 37, and 35% for women with parities 2, 3 and 3+ respectively (OR:0.60, 95% CI: 0.43-0.83, OR: 0.37, 95% CI: 0.25-0.56, OR:0.35, 95% CI: 0.25-0.54). There were increased odds of 36, 52, 83% for women who belong to poorer, middle, and richer wealth quintiles respectively (OR: 1.36, 95%CI: 0.85-2.18, OR: 1.52, 95% CI: 0.97-2.37, OR: 1.83, 95% CI: 1.20-2.80). Participants who belonged to the richest wealth quintile were more than 2 times more likely to have C-section delivery (OR: 2.14, 95%CI: 1.43-3.20). The odds of having C-section delivery reduced by 76% for women from Ningo-Prampram district (OR: 0.76, 95% CI: 0.59.0.96). Women whose household heads have Junior High level and above of education were 45% more likely to have C-section delivery (OR: 1.45, 95% CI: 1.09-1.93). CONCLUSION: Age of mother, educational level, parity, household socioeconomic status, district of residence, and level of education of household head are associated with caesarean section delivery.

RESUMO

BACKGROUND: Dihydroartemisinin-piperaquine (DHA-PQ) is one of five WHO recommended artemisinin combination therapy (ACT) for the treatment of uncomplicated malaria. However, little was known on its post-registration safety and effectiveness in sub-Saharan Africa. DHA-PQ provides a long post-treatment prophylactic effect against re-infection; however, new infections have been reported within a few weeks of treatment, especially in children. This paper reports the clinical outcomes following administration of DHQ-PQ in real-life conditions in public health facilities in Burkina Faso, Ghana, Mozambique, and Tanzania for the treatment of confirmed uncomplicated malaria. METHODS: An observational, non-comparative, longitudinal study was conducted on 10,591 patients with confirmed uncomplicated malaria visiting public health facilities within seven health and demographic surveillance system sites in four African countries (Ghana, Tanzania, Burkina Faso, Mozambique) between September 2013 and April 2014. Patients were treated with DHA-PQ based on body weight and followed up for 28 days to assess the clinical outcome. A nested cohort of 1002 was intensely followed up. Clinical outcome was assessed using the proportion of patients who reported signs and symptoms of malaria after completing 3 days of treatment. RESULTS: A total of 11,097 patients were screened with 11,017 enrolled, 94 were lost to follow-up, 332 withdrew and 10,591 (96.1%) patients aged 6 months-85 years met protocol requirements for analysis. Females were 52.8 and 48.5% were <5 years of age. Malaria was diagnosed by microscopy and rapid diagnostic test in 69.8% and 29.9%, respectively. At day 28, the unadjusted risk of recurrent symptomatic parasitaemia was 0.5% (51/10,591). Most of the recurrent symptomatic malaria patients (76%) were children <5 years. The mean haemoglobin level decreased from 10.6 g/dl on day 1 to 10.2 g/dl on day 7. There was no significant renal impairment in the nested cohort during the first 7 days of follow-up with minimal non-clinically significant changes noted in the liver enzymes. CONCLUSION: DHA-PQ was effective and well tolerated in the treatment of uncomplicated malaria and provides an excellent alternative first-line ACT in sub-Saharan Africa.

RESUMO

BACKGROUND: Sulphadoxine-Pyrimethamine (SP) is still the only recommended antimalarial for use in intermittent preventive treatment of malaria during pregnancy (IPTp) in some malaria endemic countries including Ghana. SP has the potential to cause acute haemolysis in G6PD deficient people resulting in significant haemoglobin (Hb) drop but there is limited data on post SP-IPTp Hb drop. This study determined the difference, if any in proportions of women with significant acute haemoglobin drop between G6PD normal, partial deficient and full deficient women after SP-IPTp. METHODS AND FINDINGS: Prospectively, 1518 pregnant women who received SP for IPTp as part of their normal antenatal care were enrolled. Their G6PD status were determined at enrollment followed by assessments on days 3, 7,14 and 28 to document any adverse effects and changes in post-IPTp haemoglobin (Hb) levels. The three groups were comparable at baseline except for their mean Hb (10.3 g/dL for G6PD normal, 10.8 g/dL for G6PD partial deficient and 10.8 g/dL for G6PD full defect women).The prevalence of G6PD full defect was 2.3% and 17.0% for G6PD partial defect. There was no difference in the proportions with fractional Hb drop ≥ 20% as compared to their baseline value post SP-IPTp among the 3 groups on days 3, 7, 14. The G6PD full defect group had the highest median fractional drop at day 7. There was a weak negative correlation between G6PD activity and fractional Hb drop. There was no statistical difference between the three groups in the proportions of those who started the study with Hb ≥ 8g/dl whose Hb level subsequently fell below 8g/dl post-SP IPTp. No study participant required transfusion or hospitalization for severe anaemia. CONCLUSIONS: There was no significant difference between G6PD normal and deficient women in proportions with significant acute haemoglobin drop post SP-IPTp and lower G6PD enzyme activity was not strongly associated with significant acute drug-induced haemoglobin drop post SP-IPTp but a larger study is required to confirm consistency of findings.

RESUMO

BACKGROUND: As the HIV/AIDS pandemic has evolved over recent decades, Africa has been the most affected region, even though a large proportion of HIV/AIDS deaths have not been documented at the individual level. Systematic application of verbal autopsy (VA) methods in defined populations provides an opportunity to assess the mortality burden of the pandemic from individual data. OBJECTIVE: To present standardised comparisons of HIV/AIDS-related mortality at sites across Africa and Asia, including closely related causes of death such as pulmonary tuberculosis (PTB) and pneumonia. DESIGN: Deaths related to HIV/AIDS were extracted from individual demographic and VA data from 22 INDEPTH sites across Africa and Asia. VA data were standardised to WHO 2012 standard causes of death assigned using the InterVA-4 model. Between-site comparisons of mortality rates were standardised using the INDEPTH 2013 standard population. RESULTS: The dataset covered a total of 10,773 deaths attributed to HIV/AIDS, observed over 12,204,043 person-years. HIV/AIDS-related mortality fractions and mortality rates varied widely across Africa and Asia, with highest burdens in eastern and southern Africa, and lowest burdens in Asia. There was evidence of rapidly declining rates at the sites with the heaviest burdens. HIV/AIDS mortality was also strongly related to PTB mortality. On a country basis, there were strong similarities between HIV/AIDS mortality rates at INDEPTH sites and those derived from modelled estimates. CONCLUSIONS: Measuring HIV/AIDS-related mortality continues to be a challenging issue, all the more so as anti-retroviral treatment programmes alleviate mortality risks. The congruence between these results and other estimates adds plausibility to both approaches. These data, covering some of the highest mortality observed during the pandemic, will be an important baseline for understanding the future decline of HIV/AIDS.

RESUMO

BACKGROUND: Data needed to estimate causes of death and the pattern of these deaths are scarce in sub-Saharan Africa. Such data are very important for targeting, monitoring, and evaluating health interventions. OBJECTIVE: To estimate the mortality rate and determine causes of death among adults (aged 15 years and older) in a rural district of southern Ghana, using the InterVA-4 model. DESIGN: Data used were generated from verbal autopsies conducted for registered adult members of the Dodowa Health and Demographic Surveillance System who died between 2006 and 2010. The InterVA-4 model was used to assign the cause of death. RESULTS: Overall, the mortality rate for the period under review was 7.5/1,000 person-years (py) for the general population and 10.4/1,000 py for those aged 15 and older. The leading cause of death was communicable diseases (CDs), with a malaria-specific mortality rate of 1.06/1,000 py. Pulmonary tuberculosis (TB)-specific mortality rate was the next highest (1.01/1,000 py). HIV/AIDS attributed deaths were lower among males than females. Non-communicable diseases (NCDs) contributed to 28.3% of the deaths with cause-specific mortality rate of 2.93/1,000 py. Stroke topped the list with cause-specific mortality rate of 0.69/1,000 py. As expected, young males (15-49 years) contributed to more road traffic accident (RTA) deaths; they had a lower RTA cause-specific mortality rate than older males (50-64 years). CONCLUSIONS: Data indicate that CDs (e.g. malaria and TB) remain the major cause of death with NCDs (e.g. stroke) following closely behind. Verbal autopsy data can provide the causes of mortality in poorly resourced settings where access to timely and accurate data is scarce.

RESUMO

BACKGROUND: Effective implementation of child survival interventions depends on improved understanding of cultural, social, and health system factors affecting utilization of health care. Never the less, no standardized instrument exists for collecting and interpreting information on how to avert death and improve the implementation of child survival interventions. OBJECTIVE: To describe the methodology, development, and first results of a standard social autopsy tool for the collection of information to understand common barriers to health care, risky behaviors, and missed opportunities for health intervention in deceased children under 5 years old. METHODS: Under the INDEPTH Network, a social autopsy working group was formed to reach consensus around a standard social autopsy tool for neonatal and child death. The details around 434 child deaths in Iganga/Mayuge Health and Demographic Surveillance Site (HDSS) in Uganda and 40 child deaths in Dodowa HDSS in Ghana were investigated over 12 to 18 months. Interviews with the caretakers of these children elicited information on what happened before death, including signs and symptoms, contact with health services, details on treatments, and details of doctors. These social autopsies were used to assess the contributions of delays in care seeking and case management to the childhood deaths. RESULTS: At least one severe symptom had been recognized prior to death in 96% of the children in Iganga/Mayuge HDSS and in 70% in Dodowa HDSS, yet 32% and 80% of children were first treated at home, respectively. Twenty percent of children in Iganga/Mayuge HDSS and 13% of children in Dodowa HDSS were never taken for care outside the home. In both countries most went to private providers. In Iganga/Mayuge HDSS the main delays were caused by inadequate case management by the health provider, while in Dodowa HDSS the main delays were in the home. CONCLUSION: While delay at home was a main obstacle to prompt and appropriate treatment in Dodowa HDSS, there were severe challenges to prompt and adequate case management in the health system in both study sites in Ghana and Uganda. Meanwhile, caretaker awareness of danger signs needs to improve in both countries to promote early care seeking and to reduce the number of children needing referral. Social autopsy methods can improve this understanding, which can assist health planners to prioritize scarce resources appropriately.
