Costs of promoting exclusive breastfeeding at community level in three sites in South Africa
(PLoS, 2014-01) Nkonki, Lungiswa Leonora; Daviaud, Emmanuelle; Jackson, Debra; Chola, Lumbwe; Doherty, Tanya; Chopra, Mickey; Robberstad, Bjarne
Background: Community-based peer support has been shown to be effective in improving exclusive breastfeeding rates in a variety of settings. Methods: We conducted a cost analysis of a community cluster randomised-controlled trial (Promise-EBF), aimed at promoting exclusive infant feeding in three sites in South Africa. The costs were considered from the perspective of health service providers. Peer supporters in this trial visited women to support exclusive infant feeding, once antenatally and four times postpartum. Results: The total economic cost of the Promise-EBF intervention was US$393 656, with average costs per woman and per visit of US$228 and US$52, respectively. The average costs per woman and visit in an operational ‘non research’ scenario were US$137 and US$32 per woman and visit, respectively. Investing in the promotion of exclusive infant feeding requires substantial financial commitment from policy makers. Extending the tasks of multi-skilled community health workers (CHWs) to include promoting exclusive infant feeding is a potential option for reducing these costs. In order to avoid efficiency losses, we recommend that the time requirements for delivering the promotion of exclusive infant feeding are considered when integrating it within the existing activities of CHWs. Discussion: This paper focuses on interventions for exclusive infant feeding, but its findings more generally illustrate the importance of documenting and quantifying factors that affect the feasibility and sustainability of community-based interventions, which are receiving increased focus in low income settings.
An effectiveness study of an integrated, community-based package for maternal, newborn, child and HIV care in South Africa : study protocol for a randomized controlled trial
(BioMed Central, 2011-11) Tomlinson, Mark; Doherty, Tanya; Jackson, Debra; Lawn, Joy; Ijumba, Petrida; Colvin, Mark; Nkonki, Lungiswa; Daviaud, Emmanuelle; Goga, Ameena; Sanders, David; Lombard, Carl; Persson, Lars-Ake; Ndaba, Thoko; Snetro, Gail; Chopra, Mickey
Background Progress towards MDG4 in South Africa will depend largely on scaling up effective prevention against mother to child transmission (PMTCT) of HIV and also addressing neonatal mortality. This imperative drives increasing focus on the neonatal period and particularly on the development and testing of appropriate models of sustainable, community-based care in South Africa in order to reach the poor. A number of key implementation gaps affecting progress have been identified. Implementation gaps for HIV prevention in neonates; implementation gaps for neonatal care especially home postnatal care; and implementation gaps for maternal mental health support. We have developed and are evaluating and costing an integrated and scaleable home visit package delivered by community health workers targeting pregnant and postnatal women and their newborns to provide essential maternal/newborn care as well as interventions for Prevention of Mother to Child Transmission (PMTCT) of HIV. Methods The trial is a cluster randomized controlled trial that is being implemented in Umlazi which is a peri-urban settlement with a total population of 1 million close to Durban in KwaZulu Natal, South Africa. The trial consists of 30 randomized clusters (15 in each arm). A baseline survey established the homogeneity of clusters and neither stratification nor matching was performed. Sample size was based on increasing HIV-free survival from 74% to 84%, and calculated to be 120 pregnant women per cluster. Primary outcomes are higher levels of HIV free survival and levels of exclusive and appropriate infant feeding at 12 weeks postnatally. The intervention is home based with community health workers delivering two antenatal visits, a postnatal visit within 48 hours of birth, and a further four visits during the first two months of the infants life. We are undertaking programmatic and cost effectiveness analysis to cost the intervention. Discussion The question is not merely to develop an efficacious package but also to identify and test delivery strategies that enable scaling up, which requires effectiveness studies in a health systems context, adapting and testing Asian community-based studies in various African contexts.

Evidence-based priority setting for health care and research : tools to support policy in maternal, neonatal, and child health in Africa
(Public Library of Science, 2010-07-13) Rudan, Igor; Kapiriri, Lydia; Tomlinson, Mark; Balliet, Manuela; Cohen, Barney; Chopra, Mickey
Priority setting is required in every health care system. It guides investments in health care and health research, and respects resource constraints. It happens continuously, with or without appropriate tools or processes. Although priority-setting decisions have been described as difficult, value laden, and political, only a few research groups are focused on advancing the theory of priority setting and the development and validation of priority setting tools. These groups advocate the use of their tools, but their work is often not widely recognized, especially among the policy makers in developing countries, where these tools would be most helpful. Our primary objective in this essay is to present the available tools for priority setting that could be used by policy makers in low-resource settings. We also provide an assessment of the applicability and strengths of different tools in the context of maternal and child health in sub-Saharan Africa. The analyses of investments in neglected diseases showed that they lack transparent priority-setting processes. This persisting situation results in remarkable levels of inequity between investments in different health priorities. Therefore, our secondary objective is to advocate for the use of the tools that could lead to more rational priority setting in sub-Saharan Africa. An optimal tool should be able to draw on the best local evidence and guide policy makers and governments to identify, prioritize, and implement evidence-based health interventions for scale-up and delivery.
Identifying and treating maternal mental health difficulties in Afghanistan : a feasibility study
(BMC (part of Springer Nature), 2020) Tomlinson, Mark (Mark R.); Chaudhery, Deepika; Ahmadzai, Habibullah; Rodriguez Gomez, Sofia; Bizouerne, Cecile; Van Heyningen, Thandi; Chopra, Mickey
Background: The disproportionately high burden of mental disorders in low- and middle-income countries, coupled with the overwhelming lack of resources, requires an innovative approach to intervention and response. This study evaluated the feasibility of delivering a maternal mental health service in a severely-resource constrained setting as part of routine service delivery. Methods: This exploratory feasibility study was undertaken at two health facilities in Afghanistan that did not have specialist mental health workers. Women who had given birth in the past 12 months were screened for depressive symptoms with the PHQ9 and invited to participate in a psychological intervention which was offered through an infant feeding scheme. Results: Of the 215 women screened, 131 (60.9%) met the PHQ9 criteria for referral to the intervention. The screening prevalence of postnatal depression was 61%, using a PHQ9 cut-off score of 12. Additionally, 29% of women registered as suicidal on the PHQ9. Several demographic and psychosocial variables were associated with depressive symptoms in this sample, including nutritional status of the infant, anxiety symptoms, vegetative and mood symptoms, marital difficulties, intimate partner violence, social isolation, acute stress and experience of trauma. Of the 47 (65%) women who attended all six sessions of the intervention, all had significantly decreased PHQ9 scores post-intervention. Conclusion: In poorly resourced environments, where the prevalence of postnatal depression is high, a shift in response from specialist-based to primary health care-level intervention may be a viable way to provide maternal mental health care. It is recommended that such programmes also consider home-visiting components and be integrated into existing infant and child health programmes. Manualised, evidence-based psychological interventions, delivered by non-specialist health workers, can improve outcomes where resources are scarce.
Setting health research priorities using the CHNRI method : VII. A review of the first 50 applications of the CHNRI method
(Edinburgh University Global Health Society, 2017-06) Rudan, Igor; Yoshida, Sachiyo; Chan, Kit Yee; Sridhar, Devi; Wazny, Kerri; Nair, Harish; Sheikh, Aziz; Tomlinson, Mark; Lawn, Joy E.; Bhutta, Zulfiqar A.; Bahl, Rajiv; Chopra, Mickey; Campbell, Harry; Arifeen, Shams E. l.; Black, Robert E.; Cousens, Simon
Background: Several recent reviews of the methods used to set research priorities have identified the CHNRI method (acronym derived from the “Child Health and Nutrition Research Initiative”) as an approach that clearly became popular and widely used over the past decade. In this paper we review the first 50 examples of application of the CHNRI method, published between 2007 and 2016, and summarize the most important messages that emerged from those experiences. Methods: We conducted a literature review to identify the first 50 examples of application of the CHNRI method in chronological order. We searched Google Scholar, PubMed and so–called grey literature. Results: Initially, between 2007 and 2011, the CHNRI method was mainly used for setting research priorities to address global child health issues, although the first cases of application outside this field (eg, mental health, disabilities and zoonoses) were also recorded. Since 2012 the CHNRI method was used more widely, expanding into the topics such as adolescent health, dementia, national health policy and education. The majority of the exercises were focused on issues that were only relevant to low– and middle–income countries, and national–level applications are on the rise. The first CHNRI–based articles adhered to the five recommended priority–setting criteria, but by 2016 more than two–thirds of all conducted exercises departed from recommendations, modifying the CHNRI method to suit each particular exercise. This was done not only by changing the number of criteria used, but also by introducing some entirely new criteria (eg, “low cost”, “sustainability”, “acceptability”, “feasibility”, “relevance” and others). Conclusions: The popularity of the CHNRI method in setting health research priorities can be attributed to several key conceptual advances that have addressed common concerns. The method is systematic in nature, offering an acceptable framework for handling many research questions. It is also transparent and replicable, because it clearly defines the context and priority–setting criteria. It is democratic, as it relies on “crowd–sourcing”. It is inclusive, fostering “ownership” of the results by ensuring that various groups invest in the process. It is very flexible and adjustable to many different contexts and needs. Finally, it is simple and relatively inexpensive to conduct, which we believe is one of the main reasons for its uptake by many groups globally, particularly those in low– and middle–income countries.
Setting priorities in child health research investments for South Africa
(Public Library of Science, 2007) Tomlinson, Mark; Chopra, Mickey; Sanders, Mickey; Bradshaw, Debbie; Hendricks, Michael; Greenfield, David; Black, Robert E.; Arifeen, Shams El; Rudan, Igor
This paper aims to define health research priorities in South Africa, where it is estimated that nearly 100,000 children under 5 years of age still die each year.The authors applied the methodology for setting priorities in health research investments recently developed by Child Health and Nutrition Research Initiative (CHNRI).The predominant research priorities identified within the existing South African context were health policy and systems research activities to generate new knowledge on improving delivery of the simplest and most cost-effective existing interventions.Vitamin A supplementation was ranked first, followed by hand washing, antibiotics for pneumonia, prevention of mother-to-child HIV transmission (PMTCT), and exclusive breast-feeding.The CHNRI methodology has the power to discriminate among many competing research options using a simple conceptual framework.
The use of mobile phones as a data collection tool : a report from a household survey in South Africa
(BioMed Central, 2009-12) Tomlinson, Mark; Solomon, Wesley; Singh, Yages; Doherty, Tanya; Chopra, Mickey; Ijumba, Petrida; Tsai, Alexander C.; Jackson, Debra
Background: To investigate the feasibility, the ease of implementation, and the extent to which community health workers with little experience of data collection could be trained and successfully supervised to collect data using mobile phones in a large baseline survey Methods: A web-based system was developed to allow electronic surveys or questionnaires to be designed on a word processor, sent to, and conducted on standard entry level mobile phones. Results: The web-based interface permitted comprehensive daily real-time supervision of CHW performance, with no data loss. The system permitted the early detection of data fabrication in combination with real-time quality control and data collector supervision. Conclusions: The benefits of mobile technology, combined with the improvement that mobile phones offer over PDA's in terms of data loss and uploading difficulties, make mobile phones a feasible method of data collection that needs to be further explored.
Value of a mobile information system to improve quality of care by community health workers
(AOSIS Publishing, 2013) Tomlinson, Mark; Rotheram-Borus, Mary Jane; Doherty, Tanya; Swendeman, Dallas; Tsai, Alexander C.; Ijumba, Petrida; Le Roux, Ingrid; Jackson, Debra; Stewart, Jackie; Friedman, Andi; Colvin, Mark; Chopra, Mickey
Background: We will be unable to achieve sustained impact on health outcomes with community health worker (CHW)-based interventions unless we bridge the gap between small scale efficacy studies and large scale interventions. Effective strategies to support the management of CHWs are central to bridging the gap. Mobile phones are broadly available, particularly in low and middle income countries (LAMIC), where the penetration rate approaches 100%. Objectives: In this article, we describe how mobile phones and may be combined with mobile web-based technology to assist in the management of CHWs in two projects in South Africa. Methods: This article is a descriptive study, drawing lessons from two randomised controlled trials outlining how a mobile phone information system can be utilised to enhance the quality of health interventions. We organised our comprehensive management and supervision system around a previously published management framework. The system is composed of mobile phones utilised by CHWs and a web-based interface utilised by CHW supervisors. Computerised algorithms were designed with intervention and assessment protocols to aid in the real-time supervision and management of CHWs. Results: Community health workers used mobile phones to initiate intervention visits and trigger content to be delivered during the course of intervention visits. Supervisors used the web-based interface for real-time monitoring of the location, timing and content of intervention visits. Additional real-time support was provided through direct support calls in the event of crises in the field. Conclusion: Mobile phone-based information system platforms offer significant opportunities to improve CHW-delivered interventions. The extent to which these efficiency gains can be translated into realised health gains for communities is yet to be tested.
