RESUMO

BACKGROUND: Although the majority of Ghanaian women receive antenatal care (ANC), many exhibit low health literacy by misinterpreting and incorrectly operationalizing ANC messages, leading to poor maternal and newborn health outcomes. Prior research in low-resource settings has found group antenatal care (G-ANC) feasible for women and providers. This study aims to determine the effect of G-ANC on increasing maternal health literacy. We hypothesized that pregnant women randomized into G-ANC would exhibit a greater increase in maternal health literacy than women in routine, individual ANC. METHODS: A 5-year cluster randomized controlled trial was conducted in 14 rural and peri-urban health facilities in the Eastern Region of Ghana. Facilities were paired based on patient volume and average gestational age at ANC enrollment and then randomized into intervention (G-ANC) vs. control (routine, individual ANC); 1761 pregnant women were recruited. Data collection occurred at baseline (T0) and post-birth (T2) using the Maternal Health Literacy scale, a 12-item composite scale to assess maternal health literacy. Logistic regression compared changes in health literacy from T0 to T2. RESULTS: Overall, women in both the intervention and control groups improved their health literacy scores over time (p < 0.0001). Women in the intervention group scored significantly higher on 3 individual items and on overall composite scores (p < 0.0001) and were more likely to attend 8 or more ANC visits. CONCLUSION: While health literacy scores improved for all women attending ANC, women randomized into G-ANC exhibited greater improvement in overall health literacy post-birth compared to those receiving routine individual care. Life-saving information provided during ANC must be presented in an understandable format to prevent women and newborns from dying of preventable causes. TRIAL REGISTRY: Ethical approval for the study was obtained from the Institutional Review Boards of the University of Michigan (HUM#00161464) and the Ghana Health Service (GHS-ERC: 016/04/19).

RESUMO

BACKGROUND: Inappropriate antibiotic prescriptions are a known driver of antimicrobial resistance in settings with limited diagnostic capacity. This study aimed to assess the impact of diagnostic algorithms incorporating rapid diagnostic tests on clinical outcomes and antibiotic prescriptions compared with standard-of-care practices, of acute febrile illness cases at outpatient clinics in Shai-Osudoku and Prampram districts in Ghana. METHODS: This was an open-label, centrally randomized controlled trial in 4 health facilities. Participants aged 6 months to <18 years of both sexes with acute febrile illness were randomized to receive a package of interventions to guide antibiotic prescriptions or standard care. Clinical outcomes were assessed on day 7. RESULTS: In total, 1512 patients were randomized to either the intervention (n = 761) or control (n = 751) group. Majority were children aged <5 years (1154 of 1512, 76.3%) and male (809 of 1512, 53.5%). There was 11% relative risk reduction of antibiotic prescription in intervention group (RR, 0.89; 95% CI, .79 to 1.01); 14% in children aged <5 years (RR, 0.86; 95% CI, .75 to .98), 15% in nonmalaria patients (RR, 0.85; 95% CI, .75 to .96), and 16% in patients with respiratory symptoms (RR, 0.84; 95% CI, .73 to .96). Almost all participants had favorable outcomes (759 of 761, 99.7% vs 747 of 751, 99.4%). CONCLUSIONS: In low- and middle-income countries, the combination of point-of-care diagnostics, diagnostic algorithms, and communication training can be used at the primary healthcare level to reduce antibiotic prescriptions among children with acute febrile illness, patients with nonmalarial fevers, and respiratory symptoms. CLINICAL TRIALS REGISTRATION: NCT04081051.

RESUMO

BACKGROUND: The aim was to explore behavioral factors relating to the prescription and communication of prescription-adherence messages for patients with acute febrile illness, from which to develop a training-and-communication (T&C) intervention to be delivered as part of a clinical trial. METHODS: The study undertook a content analysis of primary, qualitative data collection using in-depth interviews and focus group discussions, informed by the Capability, Opportunity, Motivation (COM-B) theory of behavior, the Theoretical Domains Framework (TDF), and Behavior Change Wheel (BCW) approach, in health facilities (39 health workers) and communities (66 community members) in the Shai-Osudoku District of Ghana. RESULTS: Health workers perceive that prescribers' and dispensers' communication with patients is influenced by the following factors: patient's educational level, existing disease conditions, health worker's workload, patient's religion, language barrier between health worker and patient, outcome of laboratory results, and medicine availability. Community members' adherence to prescription was influenced by the availability of money and affordability of medicine (outside of provision by the national health insurance scheme), the severity of the condition, work schedule, and forgetfulness. CONCLUSIONS: Our study contributes to knowledge on nesting qualitative methods in a clinical trial and reveals factors that affect the antibiotic prescription communication process. Tailored messages for patient-specific needs can shape antibiotic prescription adherence behavior and ultimately contribute to decreasing the incidence of antibiotic resistance.

RESUMO

BACKGROUND: The growing need to capture data on health and health events using faster and efficient means to enable prompt evidence-based decision-making is making the use of mobile phones for health an alternative means to capture anti-malarial drug safety data. This paper examined the feasibility and cost of using mobile phones vis-à-vis home visit to monitor adverse events (AEs) related to artemisinin-based combination therapy (ACT) for treatment of uncomplicated malaria in peri-urban Ghana. METHODS: A prospective, observational, cohort study conducted on 4270 patients prescribed ACT in 21 health facilities. The patients were actively followed by telephone or home visit to document AEs associated with anti-malarial drugs. Call duration and travel distances of each visit were recorded. Pre-paid call cards and fuel for motorbike travels were used to determine cost of conducting both follow-ups. Ms-Excel 2010 and STATA 11.2 were used for analysis. RESULTS: Of the 4270 patients recruited, 4124 (96.6 %) were successfully followed up and analyzed. Of these, 1126/4124 (27.3 %) were children under 5 years. Most 3790/4124 (91.9 %) follow-ups were done within 7 days of ACT intake. Overall, follow up by phone (2671/4124-64.8 %) was almost two times the number done by home visits (1453/4124-35.2 %). Duration of telephone calls ranged from 38 s to 53 min, costing between GH¢0.26 (0.20USD) and GH¢41.70 (27.USD). On the average, the calls lasted 3 min 51 s (SD = 3 min, 21 s) costing GH¢2.70 (0.77USD). Distance travelled for home visit ranged from 0.65 to 62 km costing GH¢0.29 (0.20USD) and GH¢279.00 (79.70USD). Thirty-two per cent (1128/4124) of patients reported AEs. In total, 1831 AE were reported, 1016/1831(55.5 %) by telephone and 815/1831 (44.5 %) by home visits. Events such as nausea, dizziness, diarrhoea, and vomiting were commonly reported. CONCLUSION: Majority of patients was successfully followed up by telephone and reported the most AEs. The cost of telephone interviewing was almost two times less than the cost of home visit. Telephone follow up should be considered for monitoring drug adverse events in low resource settings.

RESUMO

BACKGROUND: Between May 2010 and October 2012, approximately 12.5 million long-lasting insecticidal nets (LLINs) were distributed through a national universal mass distribution campaign in Ghana. The campaign included pre-registration of persons and sleeping places, door-to-door distribution of LLINs with 'hang-up' activities by volunteers and post-distribution 'keep-up' behaviour change communication activities. Hang-up activities were included to encourage high and sustained use. METHODS: The cost and cost-effectiveness of the LLIN Campaign were evaluated using a before-after design in three regions: Brong Ahafo, Central and Western. The incremental cost effectiveness of the 'hang-up' component was estimated using reported variation in the implementation of hang-up activities and LLIN use. Economic costs were estimated from a societal perspective assuming LLINs would be replaced after three years, and included the time of unpaid volunteers and household contributions given to volunteers. RESULTS: Across the three regions, 3.6 million campaign LLINs were distributed, and 45.5% of households reported the LLINs received were hung-up by a volunteer. The financial cost of the campaign was USD 6.51 per LLIN delivered. The average annual economic cost was USD 2.90 per LLIN delivered and USD 6,619 per additional child death averted by the campaign. The cost-effectiveness of the campaign was sensitive to the price, lifespan and protective efficacy of LLINs.Hang-up activities constituted 7% of the annual economic cost, though the additional financial cost was modest given the use of volunteers. LLIN use was greater in households in which one or more campaign LLINs were hung by a volunteer (OR=1.57; 95% CI=1.09, 2.27; p=0.02). The additional economic cost of the hang-up activities was USD 0.23 per LLIN delivered, and achieved a net saving per LLIN used and per death averted. CONCLUSION: In this campaign, hang-up activities were estimated to be net saving if hang-up increased LLIN use by 10% or more. This suggests hang-up activities can make a LLIN campaign more cost-effective.

RESUMO

BACKGROUND: An essential component to improving maternal and newborn outcomes is antenatal care. A trial of group antenatal care was implemented in Ghana where 7 health care facilities were randomized to be intervention sites and 7 control sites continued traditional antenatal care. Group antenatal care, where 10-14 women with similar due dates meet together for visits, includes traditional components such as risk assessment with increased opportunity for education and peer support. The study aim was to assess and report the process evaluation of the implementation of a group antenatal care intervention. METHODS: Process evaluation data were collected alongside intervention data and included both quantitative and qualitative data sources. Midwives at the health facilities which were randomized as intervention sites completed tracking logs to measure feasibility of the intervention. Research team members traveled to intervention sites where they conducted structured observations and completed fidelity and learning methods checklists to determine adherence to the model of group antenatal care delivery. In addition, midwives facilitating group antenatal care meetings were interviewed and focus groups were conducted with women participating in group antenatal care. RESULTS: In the majority of cases, midwives facilitating group antenatal care completed all components of the meetings with fidelity, following best practices such as sitting with the group rather than standing. Across 7 intervention sites, 7 groups (622 pregnant women) were documented in the tracking logs and of these participants, the majority (74%) attended more than half of the meetings, with 32% attending all 8 group meetings. Three themes were identified in both the midwife interviews and focus groups with pregnant women: 1) information sharing, 2) sense of community, and 3) time management challenges. An additional theme emerged from the focus groups with the women: women who had already given birth noticed a disconnect between what they learned and treatment received during labor and birth. CONCLUSION: This process evaluation determined that group antenatal care can be implemented with fidelity in low and middle-income countries. Time management was the biggest challenge, however both midwives and pregnant women found the model of care not only acceptable, but preferable to traditional care. The knowledge shared and sense of community built during the meetings was a valuable addition to the individual model of antenatal care.

RESUMO

INTRODUCTION: Pregnancy and postpartum-related mental health problems pose serious public health threat to the society, but worryingly, neglected in sub-Saharan Africa (SSA). This review will assess the burden and distribution of maternal mental health (MMH) problems in SSA, with the aim to inform the implementation of context sensitive interventions and policies. METHODS AND ANALYSIS: All relevant databases, grey literature and non-database sources will be searched. PubMed, LILAC, CINAHL, SCOPUS and PsycINFO, Google Scholar, African Index Medicus, HINARI, African Journals Online and IMSEAR will be searched from inception to 31 May 2023, without language restriction. The reference lists of articles will be reviewed, and experts contacted for additional studies missed by our searches. Study selection, data extraction and risk of bias assessment will be done independently by at least two reviewers and any discrepancies will be resolved through discussion between the reviewers. Binary outcomes (prevalence and incidence) of MMH problems will be assessed using pooled proportions, OR or risk ratio and mean difference for continuous outcomes; all will be presented with their 95% CIs. Heterogeneity will be investigated graphically for overlapping CIs and statistically using the I2 statistic and where necessary subgroup analyses will be performed. Random-effects model meta-analysis will be conducted when heterogeneity is appreciable, otherwise fixed-effect model will be used. The overall level of evidence will be assessed using Grading of Recommendations Assessment, Development and Evaluation. ETHICS AND DISSEMINATION: Although no ethical clearance or exemption is needed for a systematic review, this review is part of a larger study on maternal mental health which has received ethical clearance from the Ethics Review Committee of the Ghana Health Service (GHS-ERC 012/03/20). Findings of this study will be disseminated through stakeholder forums, conferences and peer review publications. PROSPERO REGISTRATION NUMBER: CRD42021269528.

RESUMO

OBJECTIVE: To assess the cost-effectiveness of two strategies of home management of under-five fevers in Ghana - treatment using antimalarials only (artesunate-amodiaquine - AAQ) and combined treatment using antimalarials and antibiotics (artesunate-amodiaquine plus amoxicillin - AAQ + AMX). METHODS: We assessed the costs and cost-effectiveness of AAQ and AAQ + AMX compared with a control receiving standard care. Data were collected as part of a cluster randomised controlled trial with a step-wedged design. Approximately, 12,000 children aged 2-59 months in Dangme West District in southern Ghana were covered. Community health workers delivered the interventions. Costs were analysed from societal perspective, using anaemia cases averted, under-five deaths averted and disability-adjusted life years (DALYs) averted as effectiveness measures. RESULTS: Total economic costs for the interventions were US$ 204,394.72 (AAQ) and US$ 260,931.49 (AAQ + AMX). Recurrent costs constituted 89% and 90% of the total direct costs of AAQ and AAQ + AMX, respectively. Deaths averted were 79.1 (AAQ) and 79.9 (AAQ + AMX), with DALYs averted being 2264.79 (AAQ) and 2284.57 (AAQ + AMX). The results show that cost per anaemia case averted were US$ 150.18 (AAQ) and US$ 227.49 (AAQ + AMX) and cost per death averted was US$ 2585.58 for AAQ and US$ 3272.20 for AAQ + AMX. Cost per DALY averted were US$ 90.25 (AAQ) and US$ 114.21 (AAQ + AMX). CONCLUSION: Both AAQ and AAQ + AMX approaches were cost-effective, each averting one DALY at less than the standard US$ 150 threshold recommended by the World Health Organisation. However, AAQ was more cost-effective. Home management of under-five fevers in rural settings is cost-effective in reducing under-five mortality.

RESUMO

BACKGROUND: While group antenatal care (ANC) has been delivered and studied in high-income countries for over a decade, it has only recently been introduced as an alternative to individual care in sub-Saharan Africa. Although the experimental design of the studies from high-resource countries have been scientifically rigorous, findings cannot be generalized to low-resource countries with low literacy rates and high rates of maternal and newborn morbidity and mortality. The Group Antenatal Care Delivery Project (GRAND) is a collaboration between the University of Michigan in the United States and the Dodowa Health Research Centre in Ghana. GRAND is a 5-year, cluster randomized controlled trial (RCT). Our intervention-group ANC-consists of grouping women by similar gestational ages of pregnancy into small groups at the first ANC visit. They then meet with the same group and the same midwife at the recommended intervals for care. OBJECTIVE: This study aims to improve health literacy, increase birth preparedness and complication readiness, and optimize maternal and newborn outcomes among women attending ANC at seven rural health facilities in the Eastern Region of Ghana. METHODS: Quantitative data will be collected at four time points using a secure web application for data collection and a database management tool. Data will be analyzed on an intention-to-treat basis to test the differences between the two arms: women randomized to group-based ANC and women randomized to routine individual ANC. We will conduct a process evaluation concurrently to identify and document patient, provider, and system barriers and facilitators to program implementation. RESULTS: The study was funded in September 2018. Recruitment and enrollment of participants and data collection started in July 2019. In November 2021, we completed participant enrollment in the study (n=1761), and we completed data collection at the third trimester in May 2022 (n=1284). Data collection at the additional three time points is ongoing: 6 weeks postpartum, 6 months postpartum, and 1 year postpartum. CONCLUSIONS: This study is significant and timely because it is among the first RCTs to be conducted to examine the effects of group ANC among low-literacy and nonliterate participants. Our findings have the potential to impact how clinical care is delivered to low-literacy populations, both globally and domestically, to improve maternal and newborn outcomes.

RESUMO

BACKGROUND: Ghana malaria control programme recommends the uptake of five doses of sulfadoxine pyrimethamine (SP) during pregnancy following the review of the World Health Organization recommendations in 2012. The uptake of higher doses of SP since the implementation of the new policy in 2016, has been low across the country. The current study determined factors that can be improved to increase uptake of SP for intermittent preventive treatment of malaria in pregnancy (IPTp-SP). METHODS: A cross-sectional analytical study was carried out among women who had just delivered in selected health facilities in the Sekondi-Takoradi Metropolis of Ghana. Participants were enrolled from the lying-in wards of the study facilities after delivery. Data including time of initiating antenatal care (ANC), number of visits, time of first dose of SP and number of doses were collected. ANC books were also reviewed. Logistic and ordered logistic regression analysis were done to determine respondent factors associated with uptake of IPTp-SP using Stata 15. RESULTS: Out of the 496 mothers who participated in the study, 370 (74.60%) initiated ANC during the first trimester, 123 (24.80%) during the second, with only three (0.60%) starting during the third trimester. Majority (463/496, 93.35%) made > 4 visits. Uptake of at least one dose of SP was 98.79% (490/496), ≥ 2 doses was 92.75 (460/496), ≥ 3 doses was 80.65% (400/496) and ≥ 4 doses was 40.32% (200/496). Uptake of IPTp 5 was very low (6.65%, 33/490). A unit increase of one ANC visit was associated with 20% higher odds of receiving 3-4 doses of SP with respect to receiving 1-2 doses (p <  0.001). The probability of receiving 5 or more doses of SP with respect to 1-2 doses was 26% higher with a unit increase of one ANC visit. CONCLUSION: Uptake of 3-4 doses and ≥ 5 doses of SP were associated with making more ANC visits. Encouraging and motivating expectant mothers to make more ANC visits can improve uptake of ≥5 doses of SP.

RESUMO

BACKGROUND: Socio-economic growth in many low and middle-income countries has resulted in more available, though not equitably accessible, healthcare. Such growth has also increased demands from citizens for their health systems to be more responsive to their needs. This paper shares a protocol for the RESPONSE study which aims to understand, co-produce, implement and evaluate context-sensitive interventions to improve health systems responsiveness to health needs of vulnerable groups in Ghana and Vietnam. METHODS: We will use a realist mixed-methods theory-driven case study design, combining quantitative (household survey, secondary analysis of facility data) and qualitative (in-depth interviews, focus groups, observations and document and literature review) methods. Data will be analysed retroductively. The study will comprise three Phases. In Phase 1, we will understand actors' expectations of responsive health systems, identify key priorities for interventions, and using evidence from a realist synthesis we will develop an initial theory and generate a baseline data. In Phase 2, we will co-produce jointly with key actors, the context-sensitive interventions to improve health systems responsiveness. The interventions will seek to improve internal (i.e. intra-system) and external (i.e. people-systems) interactions through participatory workshops. In Phase 3, we will implement and evaluate the interventions by testing and refining our initial theory through comparing the intended design to the interventions' actual performance. DISCUSSION: The study's key outcomes will be: (1) improved health systems responsiveness, contributing to improved health services and ultimately health outcomes in Ghana and Vietnam and (2) an empirically-grounded and theoretically-informed model of complex contexts-mechanisms-outcomes relations, together with transferable best practices for scalability and generalisability. Decision-makers across different levels will be engaged throughout. Capacity strengthening will be underpinned by in-depth understanding of capacity needs and assets of each partner team, and will aim to strengthen individual, organisational and system level capacities.

RESUMO

INTRODUCTION: Health systems responsiveness is a key objective of any health system, yet it is the least studied of all objectives particularly in low-income and middle-income countries. Research on health systems responsiveness highlights its multiple elements, for example, dignity and confidentiality. Little is known, however, about underlying theories of health systems responsiveness, and the mechanisms through which responsiveness works. This realist synthesis contributes to bridging these two knowledge gaps. METHODS AND ANALYSIS: In this realist synthesis, we will use a four-step process, comprising: mapping of theoretical bases, formulation of programme theories, theory refinement and testing of programme theories using literature and empirical data from Ghana and Vietnam. We will include theoretical and conceptual pieces, reviews, empirical studies and grey literature, alongside the primary data. We will explore responsiveness as entailing external and internal interactions within health systems. The search strategy will be purposive and iterative, with continuous screening and refinement of theories. Data extraction will be combined with quality appraisal, using appropriate tools. Each fragment of evidence will be appraised as it is being extracted, for its relevance to the emerging programme theories and methodological rigour. The extracted data pertaining to contexts, mechanisms and outcomes will be synthesised to identify patterns and contradictions. Results will be reported using narrative explanations, following established guidance on realist syntheses. ETHICS AND DISSEMINATION: Ethics approvals for the wider RESPONSE (Improving health systems responsiveness to neglected health needs of vulnerable groups in Ghana and Vietnam) study, of which this review is one part, were obtained from the ethics committees of the following institutions: London School of Hygiene and Tropical Medicine (ref: 22981), University of Leeds, School of Medicine (ref: MREC19-051), Ghana Health Service (ref: GHS-ERC 012/03/20) and Hanoi University of Public Health (ref: 020-149/DD-YTCC).We will disseminate results through academic papers, conference presentations and stakeholder workshops in Ghana and Vietnam.

RESUMO

BACKGROUND: Artesunate-amodiaquine (AS-AQ) was introduced in Ghana as the first line drug for treatment of uncomplicated malaria in 2004. We report the perceptions of malaria and malaria treatment behaviour, the community awareness of and perceptions about AS-AQ two years after the introduction of this ACT treatment for malaria. METHODS: Two surveys were conducted; a cross-sectional survey of 729 randomly selected household heads (urban-362, rural-367) and 282 women with children < 5 years (urban-121, rural-161) was conducted in 2006. A district wide survey was conducted in 2007 to assess awareness of AS-AQ. These were complemented with twenty-eight focus group discussions (FGDs) and 16 key informant interviews (KII) among community members and major stakeholders in the health care delivery services. All nine (9) health facilities and five (5) purposively selected drug stores were audited in order to identify commonly used anti-malarials in the study area at the time of the survey. RESULTS: Majority of respondents ( > 75%) in the sampled survey mentioned mosquito bites as the cause of malaria. Other causes mentioned include environmental factors (e.g. dirty surroundings) and standing in the sun. Close to 60% of the household heads and 40% of the care-givers interviewed did not know about AS-AQ. The community respondents who knew about and had ever taken AS-AQ perceived it to be a good drug; although they mentioned they had experienced some side effects including headaches and body weakness. Co-blistered AS-AQ was available in all the government health facilities in the study area. Different formulations of ACTs were however found in urban chemical shops but not in rural chemical stores where monotherapy antimalarials were predominant. CONCLUSION: The knowledge of fever as a symptom of malaria is high among the study population. The awareness of AS-AQ therapy and its side-effect was low in the study area. Community education and sensitization, targeting all categories of the population, has to be intensified to ensure an efficient implementation process.

BACKGROUND: Information on the epidemiology of malaria is essential for designing and interpreting results of clinical trials of drugs, vaccines and other interventions. As a background to the establishment of a site for anti-malarial drugs and vaccine trials, the epidemiology of malaria in a rural site in central Ghana was investigated. METHODS: Active surveillance of clinical malaria was carried out in a cohort of children below five years of age (n = 335) and the prevalence of malaria was estimated in a cohort of subjects of all ages (n = 1484) over a 12-month period. Participants were sampled from clusters drawn around sixteen index houses randomly selected from a total of about 22,000 houses within the study area. The child cohort was visited thrice weekly to screen for any illness and a blood slide was taken if a child had a history of fever or a temperature greater than or equal to 37.5 degree Celsius. The all-age cohort was screened for malaria once every eight weeks over a 12-month period. Estimation of Entomological Inoculation Rate (EIR) and characterization of Anopheline malaria vectors in the study area were also carried out. RESULTS: The average parasite prevalence in the all age cohort was 58% (95% CI: 56.9, 59.4). In children below five years of age, the average prevalence was 64% (95% CI: 61.9, 66.0). Geometric mean parasite densities decreased significantly with increasing age. More than 50% of all children less than 10 years of age were anaemic. Children less than 5 years of age had as many as seven malaria attacks per child per year. The attack rates decreased significantly with increasing cut-offs of parasite density. The average Multiplicity of Infection (MOI) was of 6.1. All three pyrimethamine resistance mutant alleles of the Plasmodium falciparum dhfr gene were prevalent in this population and 25% of infections had a fourth mutant of pfdhps-A437G. The main vectors were Anopheles funestus and Anopheles gambiae and the EIR was 269 infective bites per person per year. CONCLUSION: The transmission of malaria in the forest-savanna region of central Ghana is high and perennial and this is an appropriate site for conducting clinical trials of anti-malarial drugs and vaccines.

RESUMO

BACKGROUND: Intermittent preventive treatment of malaria in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) decreases placental parasitaemia and improves birth outcomes. Currently, WHO recommends three or more doses of SP given during antenatal care (ANC), spaced one month apart after 16 weeks of gestation till delivery. This study determined the level of uptake of SP and its association with birth outcomes in rural northern Ghana. METHODS: A survey was carried out at the War Memorial Hospital in Navrongo, Ghana, among mothers who had delivered within ten weeks and were seeking postnatal care. Data on time of first ANC, number of visits, receipt of IPTp-SP, and birth outcomes were extracted from the antenatal records of 254 mothers. Mothers were interviewed on their background characteristics and obstetric history. Chi-square tests and logistic regression were carried out to determine association between antenatal indicators, uptake of IPTp-SP, and birth outcomes using Stata version 13. RESULTS: Uptake of three-five doses of SP was IPT3 =76.4%, IPT4 =37.3%, and IPT5 = 16.0%. Receipt of first dose of SP at 16, 17-24, and 25-36 weeks of gestation was 16.9%, 56.7%, and 26.4%, respectively. Taking the first dose of SP during the second trimester allowed for taking ≥3 doses of SP compared to taking the first dose during the third trimester (χ2 = 60.1, p<0.001). Women who made ≥4 visits were more likely to receive ≥3 doses of SP compared to those who made <4 visits (χ2 = 87.6, p<0.001). Women who received ≥ 3 doses of SP were more likely (OR = 3.3; 95% CI: 1.69-6.33) to give birth at term and also have normal weight babies (OR =4.0; 95% CI: 1.98-8.06). CONCLUSION: Uptake of three or more doses of SP contributed to improved pregnancy outcomes. Increased efforts towards improving early ANC attendance could increase uptake of SP and improve pregnancy outcomes.

RESUMO

BACKGROUND: The goal of Roll Back Malaria (RBM) is to reduce malaria morbidity and mortality by 50% by the year 2010, and still further thereafter until the disease becomes no more a threat to public health. To contribute to the monitoring and evaluation process of this goal, two surveys were carried out in 2000 and 2003 in households and health facilities in the Kassena-Nankana district, northern Ghana using the RBM-WHO/AFRO monitoring and evaluation tools for malaria control activities. METHODS: Data were collected from mothers/caretakers on signs/symptoms of the most recent malaria attack for their under five year old children; the management actions that they took and their perception of health services provided at the health facilities, bednet use, antenatal attendance and place of delivery for the most recent pregnancy, malaria prophylaxis during their last pregnancy. Community health workers and herbalist/traditional healers were also interviewed about the types of health services they provide to community members. RESULTS: The results revealed a significant improvement in knowledge among mothers/caretakers over the three-year period; this affected caretakers' initial management of illnesses of their young children. The management in terms of the type and dosage of drugs used also improved significantly (p < 0.0001) over the period. Reported insecticide-treated bed net use among children under-five years and pregnant women significantly increased between 2000 and 2003 (p < 0.0001). Health professionals had improved on adoption of their quality of care roles. The intensification of malaria control activities and awareness creation in this district over a three year period had started demonstrating positive results towards reducing malaria disease burden. CONCLUSION: Periodic performance assessments through surveys as described and prompt feedback of results to stakeholders in the locality serves as a catalyst to improving malaria control in malaria-endemic countries.

RESUMO

BACKGROUND: Complete and accurate information on disease occurrence is crucial for effective public health response to disease outbreaks. In response to the 2014 Ebola epidemic in West Africa, Ghana intensified surveillance for the disease across the country. However, the case definition provided by the Ministry of Health was not uniformly applied at all reporting health facilities. OBJECTIVE: This paper analyses the accompanying Case Record Forms (CRFs) submitted to Noguchi Memorial Institute for Medical Research to determine its completeness and appropriateness for instituting an effective response to the epidemic. METHODS: We determined the proportions of completeness in reporting for all criteria provided by the MOH for the clinical diagnosis of Ebola. New indicators were generated to measure the completeness of each variable. Tables and graphs of completeness of indicators were produced and presented. RESULTS: Of the 156 samples, 69% were from males. Approximately 4.5% had no record for age. The date of specimen collection was filled for 96%; 34.6% (54) did not have date of onset of symptoms. In 37.8% (59) of cases, location was blank. In 12% of cases, no symptoms were recorded and about 30% had no record of fever. Travel history, especially to affected areas, was missing for 40.4%. CONCLUSIONS: Gaps on CRFs can significantly reduce the utility of results of laboratory analysis for outbreak control. Although all the samples analysed were negative for Ebola Virus, the high proportion of missing data on the forms should be a source of concern. We recommend that frontline health staff be trained on the importance of capturing all information required on the form. SOURCE OF FUNDING: The funding for the analysis of suspected samples were provided partially by Ghana Health Servce and research funding from Noguchi Memorial Institute for Medical Research.

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

Emergency contraception (EC) refers to methods that women can use to prevent pregnancy after unprotected sexual intercourse, method failure, or incorrect use. There is growing worldwide acceptance and promotion of EC as a measure to reduce the level of unwanted pregnancies and, hence, unsafe abortions. The potential effect of EC in this regard could be most evident in sub-Saharan Africa. In Ghana, the Ministry of Health has since 1996 included EC in its reproductive health service policy and standards. The Planned Parenthood Association of Ghana is the only agency involved in the promotion of EC in the country. Very little is known about societal perception of EC. We undertook a study to assess knowledge and attitude toward EC among a sample of students at the University of Ghana. We used a two-page, self-administered questionnaire in a cross-sectional study among students chosen by random sampling. The aspects of EC assessed included level of knowledge, extent of use, common traditional methods of emergency contraception, as well as socially and culturally acceptable ways to promote EC in Ghana. We also assessed how the availability of EC could influence the use of condoms among male respondents. Less than half (43.2%) of the 194 respondents (88 males and 106 females) had heard of modern emergency contraceptive methods. Postinor-2, a dedicated emergency contraceptive product, which was already on the Ghanaian market, was known to 1.5% of respondents. Only 11.3% of respondents indicated correctly the recommended time within which emergency contraceptive pills (ECPs) are to be taken after unprotected sex. Taking concentrated sugar solutions, having an enema, and douching were commonly used traditional methods of EC. More than half (55.0%) of the male respondents indicated that they would either "certainly" or "probably" reduce how often they used condoms once they knew that EC was available. Almost all (97.4%) the respondents wanted to learn more about EC. The indications from this study are that the promotion of EC in Ghana is desired and must be encouraged. The fact that EC does not offer protection against sexually transmitted infections should always be emphasized.

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.
