RESUMO

BACKGROUND: Risk factors for postnatal depression (PND), one of the most pervasive complications of child bearing, are poorly understood in Africa. A recent systematic review of 31 studies found that the strongest predictors are social and economic disadvantage and gender-based factors; only six of these studies were community based, and almost all were in South Asia. METHODS: Cohort study nested within 4 weekly surveillance of all women of reproductive age to identify pregnancies and collect data on births and deaths in the Kintampo Health Research Centre study area of Ghana. Women were screened for depression during pregnancy and after birth using the Patient Health Questionnaire to ascertain DSM-IV major or minor depression. Information was collected on determinants relating to the mother, birth, and baby, which were examined using logistic regression; effect sizes reported as relative risks with 95% confidence intervals. RESULTS: Thirteen thousand nine hundred and twenty nine women were screened both during pregnancy and after birth, of whom 13,360 (95.9%) had complete data on potential determinants. Two hundred and fifty five (3.8%, 95% CI: 3.5%, 4.1%) had PND. Antenatal depression (AND) was the strongest determinant accounting for 34.4% of PND cases. Other determinants were season of delivery, peripartum/postpartum complications, newborn ill health, still birth, or neonatal death. Common determinants were observed for onset and persistent depression. CONCLUSIONS: Although most AND resolves in this setting, more than a third of women with PND also had AND. Adverse birth- and baby-related outcomes are the other main determinants. We recommend that programs detect and treat depression during pregnancy and provide support to women with adverse birth outcomes.

RESUMO

BACKGROUND: In 2009, on the basis of promising evidence from trials in south Asia, WHO and UNICEF issued a joint statement about home visits as a strategy to improve newborn survival. In the Newhints trial, we aimed to test this home-visits strategy in sub-Saharan Africa by assessing the effect on all-cause neonatal mortality rate (NMR) and essential newborn-care practices. METHODS: The Newhints cluster randomised trial was undertaken in 98 zones in seven districts in the Brong Ahafo Region, Ghana. 49 zones were randomly assigned to the Newhints intervention and 49 to the control intervention by use of restricted randomisation with stratification to ensure comparability between interventions. Community-based surveillance volunteers (CBSVs) in Newhints zones were trained to identify pregnant women in their community and to make two home visits during pregnancy and three in the first week of life to promote essential newborn-care practices, weigh and assess babies for danger signs, and refer as necessary. Primary outcomes were NMR and coverage of key essential newborn-care practices. Analyses were by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00623337. FINDINGS: 16,168 (99%) of 16,329 deliveries between November, 2008, and December, 2009, were livebirths; the status at 1 month was known for 15,619 (97%) livebirths. 482 neonatal deaths were recorded. Coverage data were available from 6029 women in Newhints zones; of these 4358 (72%) reported having CBSV visits during pregnancy and 3815 (63%) reported having postnatal visits. This coverage increased substantially from June, 2009, after the introduction of new implementation strategies and reached almost 90% for pregnancy visits by the end of the trial and 75% for postnatal visits. The Newhints intervention significantly increased coverage of key essential newborn-care behaviours, except for four or more antenatal-care visits (5975 [76%] of 7859 vs 5988 [74%] of 8121, respectively; relative risk 1·02, 95% CI 0·96-1·09; p=0·52) and baby delivered in a facility (5373 [68%] vs 5539 [68%], respectively; 0·97, 0·81-1·14; p=0·69). The largest increase was for care-seeking, with 102 (77%) of 132 sick babies in Newhints zones taken to a hospital or clinic compared with 77 (55%) of 139 in control zones (1·43, 1·17-1·76; p=0·001). Increases were also noted in bednet use during pregnancy (5398 [69%] of 7859 vs 5135 [63%] of 8121, respectively; 1·12, 1·03-1·21; p=0·005), money saved for delivery or emergency (5730 [86%] of 6681 vs 5525 [80%] of 6941, respectively; 1·09, 1·05-1·12; p<0·0001), transport arranged in advance for facility (2496 [37%] vs 2061 [30%], respectively; 1·30, 1·12-1·49; p=0·0004), birth assistant for home delivery washed hands with soap (1853 [93%] of 1992 vs 1817 [87%] of 2091, respectively; 1·05, 1·02-1·09; p=0·001), initiation of breastfeeding in less than 1 h of birth (3743 [49%] of 7673 vs 3280 [41%] of 7921, respectively; 1·22, 1·07-1·40; p=0·004), skin to skin contact (3355 [44%] vs 1931 [24%], respectively; 2·30, 1·85-2·87; p=0·0002), first bath delayed for longer than 6 h (3131 [41%] vs 2269 [29%], respectively; 1·65, 1·27-2·13; p<0·0001), exclusive breastfeeding for 26-32 days (1217 [86%] of 1414 vs 1091 [80%] of 1371; 1·10, 1·04-1·16; p=0·001), and baby sleeping under bednet for 8-56 days (4548 [79%] of 5756 vs 4291 [73%] of 5846; 1·09, 1·03-1·15; p=0·002). There were 230 neonatal deaths in the Newhints zones compared with 252 in the control zones. The overall NMRs per 1000 livebirths were 29·8 and 31·9, respectively (0·92, 0·75-1·12; p=0·405). INTERPRETATION: The reduction in NMR with Newhints is consistent with the reductions achieved in three trials undertaken in programme settings in south Asia. Because there is no suggestion of any heterogeneity (p=0·850) between these trials and Newhints, the meta-analysis summary estimate of a reduction of 12% (95% CI 5-18) provides the best evidence for the likely effect of the home-visits strategy delivered within programmes in sub-Saharan Africa and in south Asia. Improvements in the quality of delivery and neonatal care in health facilities and development of innovative, effective strategies to increase coverage of home visits on the day of birth could lead to the achievement of more substantial reductions.

RESUMO

OBJECTIVES: To assess the extent of socio-economic inequity in coverage and timeliness of key childhood immunisations in Ghana. METHODS: Secondary analysis of vaccination card data collected from babies born between January 2008 and January 2010 who were registered in the surveillance system supporting the ObaapaVita and Newhints Trials was carried out. 20 251 babies had 6 weeks' follow-up, 16 652 had 26 weeks' follow-up, and 5568 had 1 year's follow-up. We performed a descriptive analysis of coverage and timeliness of vaccinations by indicators for urban/rural status, wealth and educational attainment. The association of coverage with socio-economic indicators was tested using a chi-square-test and the association with timeliness using Cox regression. RESULTS: Overall coverage at 1 year of age was high (>95%) for Bacillus Calmette-Guérin (BCG), all three pentavalent diphtheria-pertussis-tetanus-haemophilus influenzae B-hepatitis B (DPTHH) doses and all polio doses except polio at birth (63%). Coverage against measles and yellow fever was 85%. Median delay for BCG was 1.7 weeks. For polio at birth, the median delay was 5 days; all other vaccine doses had median delays of 2-4 weeks. We found substantial health inequity across all socio-economic indicators for all vaccines in terms of timeliness, but not coverage at 1 year. For example, for the last DPTHH dose, the proportion of children delayed more than 8 weeks were 27% for urban children and 31% for rural children (P < 0.001), 21% in the wealthiest quintile and 41% in the poorest quintile (P < 0.001), and 9% in the most educated group and 39% in the least educated group (P < 0.001). However, 1-year coverage of the same dose remained above 90% for all levels of all socio-economic indicators. CONCLUSIONS: Ghana has substantial health inequity across urban/rural, socio-economic and educational divides. While overall coverage was high, most vaccines suffered from poor timeliness. We suggest that countries achieving high coverage should include timeliness indicators in their surveillance systems.

RESUMO

OBJECTIVE: To determine the effect of weekly low-dose vitamin A supplementation on cause-specific mortality in women of reproductive age in Ghana. METHODS: A cluster-randomized, triple-blind, placebo-controlled trial was conducted in seven districts of the Brong Ahafo region of Ghana. Women aged 15-45 years who were capable of giving informed consent and intended to live in the trial area for at least 3 months were enrolled and randomly assigned, according to their cluster of residence, to receive oral vitamin A (7500 µg) or placebo once a week. Randomization was blocked, with two clusters in each fieldwork area allocated to vitamin A and two to placebo. Every 4 weeks, fieldworkers distributed capsules and collected data during home visits. Verbal autopsies were conducted by field supervisors and reviewed by physicians, who assigned a cause of death. Cause-specific mortality rates in both arms were compared by means of random-effects Poisson regression models to allow for the cluster randomization. Analysis was by intention-to-treat, based on cluster of residence, with women eligible for inclusion once they had consistently received the supplement or placebo capsules for 6 months. FINDINGS: The analysis was based on 581 870 woman-years and 2624 deaths. Cause-specific mortality rates were found to be similar in the two study arms. CONCLUSION: Low-dose vitamin A supplements administered weekly are of no benefit in programmes to reduce mortality in women of childbearing age.


Résumé OBJECTIF: Déterminer l'effet de la supplémentation hebdomadaire en vitamine A à faible dose sur la mortalité spécifique des femmes en âge de procréer au Ghana. MÉTHODES: Une étude randomisée, en triple aveugle, contrôlée contre placebo, a été menée dans sept districts de la région de Brong Ahafo au Ghana. Les femmes âgées de 15 à 45 ans, capables de donner un consentement éclairé et amenées à vivre dans la région de l'étude pendant au moins 3 mois, ont été incluses et il a été déterminé qu'elles recevraient une fois par semaine, au hasard selon leur groupe de résidence, de la vitamine A par voie orale (7 500 µg) ou un placebo. La randomisation a été fixée par deux groupes dans chaque zone recevant la vitamine A et deux groupes recevant le placebo. Toutes les 4 semaines, les agents de terrain distribuaient les capsules et recueillaient les données lors de visites à domicile. Des autopsies orales ont été effectuées par les superviseurs sur le terrain et analysées par des médecins, qui déterminaient la cause du décès. Les taux de mortalité spécifique dans les deux groupes ont été comparés à l'aide d'une régression de Poisson pour valider la randomisation des groupes. L'analyse, basée sur l'intention de traiter, était basée sur le groupe de résidence, pour des femmes éligibles à l'étude ayant reçu les capsules de supplément ou de placebo de manière constante pendant 6 mois. RÉSULTATS: L'analyse s'est basée sur 581 870 années-femmes et 2624 décès. Les taux de mortalité spécifique ont été jugés similaires dans les deux groupes de l'étude. CONCLUSION: Les suppléments en vitamine A à faible dose administrés hebdomadairement ne sont d'aucune utilité dans les programmes visant à réduire la mortalité chez les femmes en âge de procréer.


Resumen OBJETIVO: Determinar el efecto de la administración semanal de dosis bajas de vitamina A en la mortalidad por causas específicas de mujeres en edad reproductiva en Ghana. MÉTODOS: Se realizó un ensayo aleatorio de grupos, triple ciego y controlado por placebo en siete distritos de la región de Brong Ahafo, en Ghana. Se inscribieron mujeres de entre 15 y 45 años de edad capaces de dar su consentimiento informado y que tuvieran previsto vivir en el área de ensayo durante al menos tres meses. De acuerdo con el grupo de residencia al que habían sido asignadas de forma aleatoria, recibieron semanalmente vitamina A por vía oral (7500 µg) o placebo. La distribución aleatoria se limitó en cada área de trabajo a dos grupos a los que se les administró vitamina A y dos grupos que recibieron placebo. Cada cuatro semanas, los investigadores de campo distribuyeron cápsulas y recogieron datos durante las visitas a los hogares. Las autopsias verbales realizadas por los supervisores de campo fueron revisadas por médicos, quienes determinaron la causa de la muerte. Se compararon las tasas de mortalidad por causas específicas de ambos brazos mediante los modelos de regresión de Poisson con efectos aleatorios para facilitar la distribución aleatoria de los grupos. El análisis fue por intención de tratar, según el grupo de residencia y con mujeres que cumplieron las condiciones de inclusión una vez habían recibido de forma constante las cápsulas de suplemento o placebo durante seis meses. RESULTADOS: El análisis se basó en 581 870 años-mujer y 2624 muertes. Se descubrió que las tasas de mortalidad por causas específicas fueron similares en ambos brazos del estudio. CONCLUSIÓN: Los suplementos de dosis bajas de vitamina A administrados semanalmente no presentan ninguna ventaja en los programas para reducir la mortalidad de las mujeres en edad reproductiva.

RESUMO

OBJECTIVE: To evaluate whether the Newhints home visits intervention increased the adoption of skin-to-skin care (SSC), in particular, among low birthweight (LBW) (<2.5 kg) babies. METHODS: A cluster-randomised trial, with 49 Newhints zones and 49 control zones, was conducted in seven districts in the Brong Ahafo Region, Ghana. It included all live births between November 2008 and December 2009. In Newhints zones, existing community-based surveillance volunteers were trained to conduct home visits during which they weighed babies and counselled mothers of LBW babies on SSC. Performance of any SSC and SSC for more than 2 h was evaluated. RESULTS: Of 15,615 live births, 68.5% had recorded birthweights; 10.1% were LBW. Any SSC was 19.4% higher among babies in Newhints vs. control zones (risk ratio, RR: 1.81; 95% confidence interval, CI: 1.40-2.35). Performance of SSC for more than 2 h was, however, low, at only 7.5%, although more than double compared with control zones (RR: 2.72; 95% CI: 1.80-4.10). LBW babies visited and weighed by a volunteer were more likely to receive SSC (PA ny  = 0.005; P >  2 h  = 0.021), greater for LBW babies, particularly for more than 2 h of SSC (Pinteraction  = 0.050). CONCLUSION: Newhints successfully promoted the uptake of SSC in rural Ghana. Although findings are encouraging, promotion in rural community settings in sub-Saharan Africa is challenging. Lessons learned can help shape SSC promotion in efforts to increase adoption and save newborn lives.

RESUMO

BACKGROUND: Globally, about 350.000 women die every year from pregnancy related causes and more than half of these deaths occur in sub-Saharan Africa (SSA). Approximately 12% of the maternal deaths are associated with hypertensive disorders in pregnancy such as pregnancy induced hypertension (PIH). However, very little is known about PIH and associated determinants in many SSA countries such as Ghana. We therefore sought to assess rural and urban differences in blood pressure (BP) and PIH among pregnant women in Ghana. METHODS: We conducted a cross-sectional study among 967 rural (677) and urban (290) pregnant women with a gestational age of more than 20 weeks. PIH was defined as a systolic blood pressure of ≥140 mmHg and/or diastolic blood pressure of ≥90 mmHg. RESULTS: Women in urban Ghana had a higher mean systolic and diastolic BP than women in rural Ghana (105/66 mmHg versus 102/61 mmHg, p < 0.001 for both systolic and diastolic BP). The prevalence of PIH was also higher in urban Ghana (3.1%) than in rural Ghana (0.4%) (p = 0.014). The urban and rural difference in mean diastolic blood pressure persisted even after adjustments for the study characteristics in a linear regression model. In both rural and urban Ghana, BMI, heart rate and a family history of hypertension were independently associated with BP. CONCLUSION: Our findings suggest higher mean BP levels and PIH in urban Ghana than in rural Ghana. BMI was independently related to high BP. Left unchecked, the increasing prevalence of overweight and obesity in Ghana will exacerbate PIH levels in Ghana.

RESUMO

BACKGROUND: Mobile health (mHealth) describes the use of portable electronic devices with software applications to provide health services and manage patient information. With approximately 5 billion mobile phone users globally, opportunities for mobile technologies to play a formal role in health services, particularly in low- and middle-income countries, are increasingly being recognized. mHealth can also support the performance of health care workers by the dissemination of clinical updates, learning materials, and reminders, particularly in underserved rural locations in low- and middle-income countries where community health workers deliver integrated community case management to children sick with diarrhea, pneumonia, and malaria. OBJECTIVE: Our aim was to conduct a thematic review of how mHealth projects have approached the intersection of cellular technology and public health in low- and middle-income countries and identify the promising practices and experiences learned, as well as novel and innovative approaches of how mHealth can support community health workers. METHODS: In this review, 6 themes of mHealth initiatives were examined using information from peer-reviewed journals, websites, and key reports. Primary mHealth technologies reviewed included mobile phones, personal digital assistants (PDAs) and smartphones, patient monitoring devices, and mobile telemedicine devices. We examined how these tools could be used for education and awareness, data access, and for strengthening health information systems. We also considered how mHealth may support patient monitoring, clinical decision making, and tracking of drugs and supplies. Lessons from mHealth trials and studies were summarized, focusing on low- and middle-income countries and community health workers. RESULTS: The review revealed that there are very few formal outcome evaluations of mHealth in low-income countries. Although there is vast documentation of project process evaluations, there are few studies demonstrating an impact on clinical outcomes. There is also a lack of mHealth applications and services operating at scale in low- and middle-income countries. The most commonly documented use of mHealth was 1-way text-message and phone reminders to encourage follow-up appointments, healthy behaviors, and data gathering. Innovative mHealth applications for community health workers include the use of mobile phones as job aides, clinical decision support tools, and for data submission and instant feedback on performance. CONCLUSIONS: With partnerships forming between governments, technologists, non-governmental organizations, academia, and industry, there is great potential to improve health services delivery by using mHealth in low- and middle-income countries. As with many other health improvement projects, a key challenge is moving mHealth approaches from pilot projects to national scalable programs while properly engaging health workers and communities in the process. By harnessing the increasing presence of mobile phones among diverse populations, there is promising evidence to suggest that mHealth can be used to deliver increased and enhanced health care services to individuals and communities, while helping to strengthen health systems.

RESUMO

BACKGROUND: The fact that tuberculosis can be treated with the DOTS strategy (Directly Observed Treatment, Short-course) is not enough to control the disease. Patients have to find their way to tuberculosis treatment first. To better understand the route to tuberculosis treatment in rural Nepal we interviewed twenty-six patients under treatment. METHODS: In semi-structured interviews patients shared their disease history and health seeking behaviour. The analysis focused on the encounters with the health care system before enrolment in the tuberculosis treatment program. RESULTS: Patient routes often started in the medical shop and led via intricate routes with multiple providers to facilities with higher qualified and more competent staff where tuberculosis was diagnosed. Several factors influenced the route to tuberculosis treatment. Besides known patients factors (such as severity of complaints, the ability to pay for services, availability of services and peer support for choosing a provider) specific health services factors were also identified. These included the perceived quality, costs and service level of a provider, and lack of provider initiated referral. Self referral because of waned trust in the provider was very common. In contrast, once tuberculosis was considered a possible diagnosis, referral to diagnostic testing and tuberculosis treatment was prompt. CONCLUSION: Patient routes towards tuberculosis treatment are characterised by self referral and include both private and public health care providers. Once tuberculosis is suspected referral for diagnosis and treatment is prompt. Given the importance of the private practitioners in the patient routes, quality improvement initiatives need to address not only the public sector but the private health care sector as well.

RESUMO

BACKGROUND: Every year, 2·9 million newborn babies die worldwide. A meta-analysis of four cluster-randomised controlled trials estimated that home visits by trained community members in programme settings in Ghana and south Asia reduced neonatal mortality by 12% (95% CI 5-18). We aimed to estimate the costs and cost-effectiveness of newborn home visits in a programme setting. METHODS: We prospectively collected detailed cost data alongside the Newhints trial, which tested the effect of a home-visits intervention in seven districts in rural Ghana and showed a reduction of 8% (95% CI -12 to 25%) in neonatal mortality. The intervention consisted of a package of home visits to pregnant women and their babies in the first week of life by community-based surveillance volunteers. We calculated incremental cost-effectiveness ratios (ICERs) with Monte Carlo simulation and one-way sensitivity analyses and characterised uncertainty with cost-effectiveness planes and cost-effectiveness acceptability curves. We then modelled the potential cost-effectiveness for baseline neonatal mortality rates of 20-60 deaths per 1000 livebirths with use of a meta-analysis of effectiveness estimates. FINDINGS: In the 49 zones randomly allocated to receive the Newhints intervention, a mean of 407 (SD 18) community-based surveillance volunteers undertook home visits for 7848 pregnant women who gave birth to 7786 live babies in 2009. Annual economic cost of implementation was US$203 998, or $0·53 per person. In the base-case analysis, the Newhints intervention cost a mean of $10 343 (95% CI 2963 to -7674) per newborn life saved, or $352 (95% CI 104 to -268) per discounted life-year saved, and had a 72% chance of being highly cost effective with respect to Ghana's 2009 gross domestic product per person. Key determinants of cost-effectiveness were the discount rate, protective effectiveness, baseline neonatal mortality rate, and implementation costs. In the scenarios modelled with the meta-analysis results, the ICER increased from $127 per life-year saved at a neonatal mortality rate of 60 deaths per 1000 livebirths, to $379 per life-year saved at a rate of 20 deaths per 1000 livebirths. The strategy had at least a 99% probability of being highly cost effective for lower-middle-income countries in all neonatal mortality rate scenarios modelled, and at least a 95% probability of being highly cost effective for low-income countries at neonatal mortality rates of 30 or more deaths per 1000 livebirths. INTERPRETATION: Our findings show that the seemingly modest mortality reductions achieved by a newborn home-visit strategy might in fact be cost effective. In Ghana, such strategies are also likely to be affordable. Our findings support recommendations from WHO and UNICEF that low-income and middle-income countries implement newborn home visits.

RESUMO

OBJECTIVES: To evaluate the impact of Newhints community-based surveillance volunteer (CBSV) assessments and referrals on access to care for sick newborns and on existing inequities in access. DESIGN: We evaluated a prospective cohort nested within the Newhints cluster-randomised controlled trial. SETTING: Community-based intervention involving more than 750 000, predominantly rural, population in seven contiguous districts in the Brong-Ahafo Region, Ghana. PARTICIPANTS: Participants were recently delivered women (from more than 120 000 women under surveillance) and their 16 168 liveborn babies. Qualitative in-depth interviews with referral narratives (IDIs) were conducted with 92 mothers, CBSVs and health facility front-desk and maternity/paediatrics ward staff. INTERVENTIONS: Newhints trained and effectively supervised 475 CBSVs (existing within the Ghana Health Service) in 49 of 98 supervisory zones (clusters) to assess and refer newborns with any of the 10-key-danger signs to health facilities within the first week after birth; promote independent care seeking for sick newborns and problem-solve around barriers between November 2008 and December 2009. PRIMARY OUTCOMES: The main evaluation outcomes were rates of compliance with referrals and independent care seeking for newborn illnesses. RESULTS: Of 4006 sampled, 2795 (69.8%) recently delivered women received CBSV assessment visits and 279 (10.0%) newborns were referred with danger signs. Compliance with referrals was unprecedentedly high (86.0%) with women in the poorest quintile (Q1) complying better than the least poor (Q5):87.5%(Q1) vs 69.7%(Q5); p=0.038. Three-quarters went to hospitals; 18% were admitted and 58% received outpatient treatment. Some (24%) mothers were turned away at facilities and follow-on IDIs showed that some of these untreated babies subsequently died. Independent care seeking for severe newborn illness increased from 55.4% in control to 77.3% in Newhints zones, especially among Q1 where care seeking almost doubled (95.0% vs 48.6%; RR=1.94 (1.32, 2.84); p=0.001). Rates were the highest among rural residents but urban residents complied quicker. CONCLUSIONS: Home visits are feasible and a potentially pro-poor approach to link sick newborns to facilities. Its effectiveness in improving survival hinges on matched improvement in facility quality of care. TRIAL REGISTRATION NUMBER: NCT00623337.

RESUMO

OBJECTIVES: To assess the impact of probable depression in the immediate postnatal period on subsequent infant mortality and morbidity. DESIGN: Cohort study nested within 4 weekly surveillance of all women of reproductive age to identify pregnancies and collect data on births and deaths. SETTING: Rural/periurban communities within the Kintampo Health Research Centre study area of the Brong-Ahafo Region of Ghana. PARTICIPANTS: 16,560 mothers who had a live singleton birth reported between 24 March 2008 and 11 July 2009, who were screened for probable postnatal depression (pPND) between 4 and 12 weeks post partum (some of whom had also had depression assessed at pregnancy), and whose infants survived to this point. PRIMARY/SECONDARY OUTCOME MEASURES: All-cause early infant mortality expressed per 1000 infant-months of follow-up from the time of postnatal assessment to 6 months of age. The secondary outcomes were (1) all-cause infant mortality from the time of postnatal assessment to 12 months of age and (2) reported infant morbidity from the time of the postnatal assessment to 12 months of age. RESULTS: 130 infant deaths were recorded and singletons were followed for 67,457.4 infant-months from the time of their mothers' postnatal depression assessment. pPND was associated with an almost threefold increased risk of mortality up to 6 months (adjusted rate ratio (RR), 2.86 (1.58 to 5.19); p=0.001). The RR up to 12 months was 1.88 (1.09 to 3.24; p=0.023). pPND was also associated with increased risk of infant morbidity. CONCLUSIONS: There is new evidence for the association between maternal pPND and infant mortality in low-income and middle-income countries. Implementation of the WHO's Mental Health Gap Action Programme (mhGAP) to scale up packages of care integrated with maternal health is encouraged as an important adjunct to child survival efforts.

RESUMO

BACKGROUND: Whilst there is compelling evidence of an almost 2-fold increased risk of still births, and suggestive evidence of increased mortality among offspring of mothers with psychotic disorders, only three studies have addressed the role of antenatal depression (AND) on survival of the baby. We examined these associations in a large cohort of pregnant women in Ghana. METHODS: A Cohort study nested within 4-weekly surveillance of all women of reproductive age to identify pregnancies and collect data on births and deaths in the Kintampo Health Research Centre study area of Ghana. Women were screened for AND using the Patient Health Questionnaire (PHQ-9) to ascertain DSM-IV major or minor depression. Outcomes were adverse birth outcomes, maternal/infant morbidity, and uptake of key newborn care practices, examined using logistic regression; effect sizes reported as relative risks with 95% confidence intervals. RESULTS: 20679 (89.6%) pregnant women completed the PHQ-9. The prevalence of AND was 9.9% (n = 2032) (95% confidence interval 9.4%-10.2%). AND was associated with: prolonged labour (RR 1.25, 95% CI 1.02-1.53); peripartum complications (RR 1.11, 95% CI 1.07-1.15); postpartum complications (RR 1.27, 96% CI 1.21-1.34); non-vaginal delivery (RR 1.19, 95% CI 1.02-1.40); newborn illness (RR 1.52, 95% CI 1.16-1.99); and bed net use during pregnancy (RR 0.93, 95% CI 0.89-0.98), but not neonatal deaths, still births, low birth weight, immediate breast feeding initiation, or exclusive breastfeeding. AND was marginally associated with preterm births (RR 1.32, 95% CI 0.98-1.76). CONCLUSION: This paper has contributed important evidence on the role of antenatal depression as a potential contributor to maternal and infant morbidity. Non-pharmacological treatments anchored on primary care delivery structures are recommended as an immediate step. We further recommend that trials are designed to assess if treating antenatal depression in conjunction with improving the quality of obstetric care results in improved maternal and newborn outcomes.

RESUMO

BACKGROUND: While depression during pregnancy is one of the strongest risk factors for postnatal depression, it has been comparatively little studied, particularly in sub-Saharan Africa. METHODS: Cohort study nested within 4-weekly surveillance of all women of reproductive age to identify pregnancies and collect data on births and deaths in the Kintampo Health Research Centre study area of Ghana. Women were screened for depression during pregnancy using the Patient Health Questionnaire to ascertain DSM-IV major or minor depression. Information on demographic factors, indicators of social and economic disadvantage, and previous obstetric history were also collected which were examined using logistic regression; effect sizes reported as relative risks with 95% confidence intervals. RESULTS: 21,135 pregnant women were screened of whom 20,920 (98.9%) had complete data on potential determinants. 2086 (9.9%, 95% CI: 9.5%-10.3%) had AND. Determinants of AND were: maternal age 30+ years (relative risk [RR], 1.16 (1.06-1.27); never married ([RR] 1.34, (1.14-1.58); lower wealth quintile ([RR], 1.30 (1.13-1.50); unplanned pregnancy ([RR], 1.55 (1.43-1.69); previous pregnancy loss ([RR], 1.30 (1.18-1.43). LIMITATIONS: We did not assess women for physical health during pregnancy, and lacked information on some potentially relevant psychosocial factors. CONCLUSION: Prevalence of antenatal depression, applying clinical criteria, is similar to that seen in high income countries. Factors related to chronic social and economic disadvantage are among the most important co-determinants. Population-level interventions that address these problems among women of reproductive age may be the most effective strategy for reducing the prevalence and impact of depression in pregnancy.

RESUMO

BACKGROUND: Community health workers (CHWs) are an increasingly important component of health systems and programs. Despite the recognized role of supervision in ensuring CHWs are effective, supervision is often weak and under-supported. Little is known about what constitutes adequate supervision and how different supervision strategies influence performance, motivation, and retention. OBJECTIVE: To determine the impact of supervision strategies used in low- and middle-income countries and discuss implementation and feasibility issues with a focus on CHWs. DESIGN: A search of peer-reviewed, English language articles evaluating health provider supervision strategies was conducted through November 2013. Included articles evaluated the impact of supervision in low- or middle-income countries using a controlled, pre-/post- or observational design. Implementation and feasibility literature included both peer-reviewed and gray literature. RESULTS: A total of 22 impact papers were identified. Papers were from a range of low- and middle-income countries addressing the supervision of a variety of health care providers. We classified interventions as testing supervision frequency, the supportive/facilitative supervision package, supervision mode (peer, group, and community), tools (self-assessment and checklists), focus (quality assurance/problem solving), and training. Outcomes included coverage, performance, and perception of quality but were not uniform across studies. Evidence suggests that improving supervision quality has a greater impact than increasing frequency of supervision alone. Supportive supervision packages, community monitoring, and quality improvement/problem-solving approaches show the most promise; however, evaluation of all strategies was weak. CONCLUSION: Few supervision strategies have been rigorously tested and data on CHW supervision is particularly sparse. This review highlights the diversity of supervision approaches that policy makers have to choose from and, while choices should be context specific, our findings suggest that high-quality supervision that focuses on supportive approaches, community monitoring, and/or quality assurance/problem solving may be most effective.

RESUMO

A World Health Organization (WHO)/United Nations Children's Fund (UNICEF) (2009) joint statement recommended home visits by community-based agents as a strategy to improve newborn survival, based on promising results from Asia. This article presents detailed evaluation of community volunteer assessment and referral implemented within the Ghana Newhints home visits cluster-Randomized Controlled Trial (RCT). It highlights the lessons learned to inform implementation/scale-up of this model in similar settings. The evaluation used a conceptual framework adopted for increasing access to care for sick newborns and involves three main steps, each with a specific goal and key requirements to achieving this. These steps are: sick newborns are identified within communities and referred; families comply with referrals and referred babies receive appropriate management at health facilities. Evaluation data included interviews with 4006 recently delivered mothers; records on 759 directly observed volunteer assessments and 52 validation of supervisors' assessments; newborn care quality assessment in 86 health facilities and in-depth interviews (IDIs) with 55 mothers, 21 volunteers and 15 health professionals. Assessment accuracy of volunteers against supervisors and physician was assessed using Kappa (agreement coefficient). IDIs were analysed by generating and indexing into themes, and exploring relationships between themes and their contextual interpretations. This evaluation demonstrated that identifying, understanding and implementing the key requirements for success in each step of volunteer assessment and referrals was pivotal to success. In Newhints, volunteers (CBSVs) were trusted by families, their visits were acceptable and they engaged mothers/families in decisions, resulting in unprecedented 86% referral compliance and increased (55-77%) care seeking for sick newborns. Poor facility care quality, characterized by poor health worker attitudes, limited the mortality reduction. The important implication for future implementation of home visits in similar settings is that, with 100% specificity but 80% sensitivity of referral decisions, volunteers might miss some danger signs but if successful implementation must translate into mortality reductions, concurrent improvement in facility newborn care quality is imperative.

RESUMO

OBJECTIVE: To assess the structural capacity for, and quality of, immediate and essential newborn care (ENC) in health facilities in rural Ghana, and to link this with demand for facility deliveries and admissions. DESIGN: Health facility assessment survey and population-based surveillance data. SETTING: Seven districts in Brong Ahafo Region, Ghana. PARTICIPANTS: Heads of maternal/neonatal wards in all 64 facilities performing deliveries. MAIN OUTCOME MEASURES: Indicators include: the availability of essential infrastructure, newborn equipment and drugs, and personnel; vignette scores and adequacy of reasons given for delayed discharge of newborn babies; and prevalence of key immediate ENC practices that facilities should promote. These are matched to the percentage of babies delivered in and admitted to each type of facility. RESULTS: 70% of babies were delivered in health facilities; 56% of these and 87% of neonatal admissions were in four referral level hospitals. These had adequate infrastructure, but all lacked staff trained in ENC and some essential equipment (including incubators and bag and masks) and/or drugs. Vignette scores for care of very low-birth-weight babies were generally moderate-to-high, but only three hospitals achieved high overall scores for quality of ENC. We estimate that only 33% of babies were born in facilities capable of providing high quality, basic resuscitation as assessed by a vignette plus the presence of a bag and mask. Promotion of immediate ENC practices in facilities was also inadequate, with coverage of early initiation of breastfeeding and delayed bathing both below 50% for babies born in facilities; this represents a lost opportunity. CONCLUSIONS: Unless major gaps in ENC equipment, drugs, staff, practices and skills are addressed, strategies to increase facility utilisation will not achieve their potential to save newborn lives.

RESUMO

Despite resurgence in the use of community health workers (CHWs) in the delivery of community case management of childhood illnesses, a paucity of evidence for effective strategies to address key constraints of worker motivation and retention endures. This work reports the results of semi-structured interviews with 15 international stakeholders, selected because of their experiences in CHW program implementation, to elicit their views on strategies that could increase CHW motivation and retention. Data were collected to identify potential interventions that could be tested through a randomized control trial. Suggested interventions were organized into thematic areas; cross-cutting approaches, recruitment, training, supervision, incentives, community involvement and ownership, information and data management, and mHealth. The priority interventions of stakeholders correspond to key areas of the work motivation and CHW literature. Combined, they potentially provide useful insight for programmers engaging in further enquiry into the most locally relevant, acceptable, and evidence-based interventions.

RESUMO

Objectives To assess the effect of vitamin A supplementation in women of reproductive age in Ghana on cause- and age-specific infant mortality. In addition, because of recently published studies from Guinea Bissau, effects on infant mortality by sex and season were assessed. Design Double-blind, cluster-randomised, placebo-controlled trial. Setting 7 contiguous districts in the Brong Ahafo region of Ghana. Participants All women of reproductive age (15-45 years) resident in the study area randomised by cluster of residence. All live born infants from 1 June 2003 to 30 September 2008 followed up through 4-weekly home visits. Intervention Weekly low-dose (25 000 IU) vitamin A. Main outcome measures Early infant mortality (1-5 months); late infant mortality (6-11 months); infection-specific infant mortality (0-11 months). Results 1086 clusters, 62 662 live births, 52 574 infant-years and 3268 deaths yielded HRs (95% CIs) comparing weekly vitamin A with placebo: 1.04 (0.88 to 1.05) early infant mortality; 0.99 (0.84 to 1.18) late infant mortality; 1.03 (0.92 to 1.16) infection-specific infant mortality. There was no evidence of modification of the effect of vitamin A supplementation on infant mortality by sex (Wald statistic =0.07, p=0.80) or season (Wald statistic =0.03, p=0.86). Conclusions This is the largest analysis of cause of infant deaths from Africa to date. Weekly vitamin A supplementation in women of reproductive age has no beneficial or deleterious effect on the causes of infant death to age 6 or 12 months in rural Ghana.

RESUMO

OBJECTIVE: Measuring quality of care through performance indicators and subsequently using these to compare, learn, and improve (benchmarking) has become a central component of health care policy. This paper aims to identify the main themes of health services research in this area and focuses on opportunities for improving the evidence underpinning performance indicators. METHODS: A literature survey was carried out to identify research activities and main research themes in Europe in the years 2000-09. Identified literature was categorized into sub-topics and for each topic the main methodological issues were identified and discussed. Experts validated the findings and explored the potential for related further European research. RESULTS: The distribution of research on performance and benchmarking across EU member states varies in time, scope and settings with a large amount of studies focusing on hospitals. Eight specific fields of research were identified (research on concepts and performance frameworks; performance indicators and benchmarking using mortality data; performance indicators and benchmarking related to cancer care; performance indicators and benchmarking on care delivered in hospitals; patient safety indicators; performance indicators in primary care; patient experience; research on the practice of benchmarking and performance improvement). Expert discussions confirmed that research on performance indicators and benchmarking should focus on the development of indicators, as well as their use. The research should involve the potential users and incorporate scientific approaches from biomedicine and epidemiology as well as the social sciences. Further progress is hampered by data availability. Issues which need to be addressed include the use of unique patient identifiers (UPIs) to facilitate linkages between separate databases; standardized measurement of the experiences of patients and others; and deepening collaboration between Eurostat, the World Health Organization (WHO), and the Organization for Economic Co-operation and Development (OECD) to facilitate the availability of internationally comparable performance information. CONCLUSIONS: This study suggests a number of themes for future research. These include testing and improving: the validity and reliability of performance indicators, especially related to avoidable mortality and other outcome indicators; the effectiveness and efficiency of embedding performance indicators in the various governance, monitoring and management models, and their effect on health systems, services and professionals; and the effectiveness and efficiency of linking performance indicators to other national and international strategies and policies such as accreditation and certification, practice guidelines, audits, quality systems, patient safety strategies, national standards on volume and/or quality, public reporting, pay-for-performance and patient/consumer involvement. The field would benefit from strengthening the clearinghouse function for research findings, training of researchers and appropriate scientific publication media. Results should be systematically shared with policy-makers and managers, and networking stimulated between the growing number of regional and national institutes involved in quality measurement and reporting.
