Effect of the Newhints home-visits intervention on neonatal mortality rate and care practices in Ghana: a cluster randomised controlled trial

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.

Interventions to Improve Motivation and Retention of Community Health Workers Delivering Integrated Community Case Management (iCCM): Stakeholder Perceptions and Priorities

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.

Supervising community health workers in low-income countries – a review of impact and implementation issues

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.Background Community health workers (CHWs) are an increasingly important component of health systems and programs.

Health services research related to performance indicators and benchmarking in Europe

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.

Socio-economic determinants and inequities in coverage and timeliness of early childhood immunisation in rural Ghana

To assess the extent of socio‐economic inequity in coverage and timeliness of key childhood immunisations in Ghana.

DETERMINANTS OF POSTNATAL DEPRESSION IN RURAL GHANA: FINDINGS FROM THE DON POPULATION BASED COHORT STUDY

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.

Quality of newborn care: a health facility assessment in rural Ghana using survey, vignette and surveillance data

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.

Effect of vitamin A supplementation in women of reproductive age on cause-specific early and late infant mortality in rural Ghana: ObaapaVitA double-blind, cluster-randomised, placebo-controlled trial.

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.

Association of Antenatal Depression with Adverse Consequences for the Mother and Newborn in Rural Ghana: Findings from the DON Population-Based Cohort Study

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.
