- ItemAssessment of the uptake of neonatal and young infant referrals by community health workers to public health facilities in an urban informal settlement, KwaZulu-Natal, South Africa(BioMed Central, 2013-02) Nsibande, Duduzile; Doherty, Tanya; Ijumba, Petrida; Tomlinson, Mark; Jackson, Debra; Sanders, David; Lawn, JoyAbstract Background Globally, 40% of the 7.6 million deaths of children under five every year occur in the neonatal period (first 28 days after birth). Increased and earlier recognition of illness facilitated by community health workers (CHWs), coupled with effective referral systems can result in better child health outcomes. This model has not been tested in a peri-urban poor setting in Africa, or in a high HIV context. Methods The Good Start Saving Newborn Lives (SNL) study (ISRCTN41046462) conducted in Umlazi, KwaZulu-Natal, was a community randomized trial to assess the effect of an integrated home visit package delivered to mothers by CHWs during pregnancy and post-delivery on uptake of PMTCT interventions and appropriate newborn care practices. CHWs were trained to refer babies with illnesses or identified danger signs. The aim of this sub-study was to assess the effectiveness of this referral system by describing CHW referral completion rates as well as mothers’ health-care seeking practices. Interviews were conducted using a structured questionnaire with all mothers whose babies had been referred by a CHW since the start of the SNL trial. Descriptive analysis was conducted to describe referral completion and health seeking behaviour of mothers. Results Of the 2423 women enrolled in the SNL study, 148 sick infants were referred between June 2008 and June 2010. 62% of referrals occurred during the first 4 weeks of life and 22% between birth and 2 weeks of age. Almost all mothers (95%) completed the referral as advised by CHWs. Difficulty breathing, rash and redness/discharge around the cord accounted for the highest number of referrals (26%, 19% and 17% respectively). Only16% of health workers gave written feedback on the outcome of the referral to the referring CHW. Conclusions We found high compliance with CHW referral of sick babies in an urban South African township. This suggests that CHWs can play a significant role, within community outreach teams, to improve newborn health and reduce child mortality. This supports the current primary health care re-engineering process being undertaken by the South African National Department of Health which involves the establishment of family health worker teams including CHWs.

- ItemAn 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, MickeyBackground 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.

- ItemThe 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, DebraBackground: 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.
- ItemValue 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, MickeyBackground: 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.
