Assessing scale-up of mHealth innovations based on intervention complexity: two case studies of child health programs in Malawi and Zambia.

As interest in mHealth (including Short Message Services or SMS) increases, it is important to assess potential benefits and limitations of this technology in improving interventions in resource-poor settings. The authors analyzed two case studies (early infant diagnosis of HIV and nutrition surveillance) of three projects in Malawi and Zambia using a conceptual framework that assesses the technical complexity of the programs, with and without the use of SMS technology. The authors based their findings on literature and discussions with key informants involved in the programs. For both interventions, introducing SMS reduced barriers to effective and timely delivery of services by simplifying the tracking and analysis of data and improving communication between healthcare providers. However, the primary implementation challenges for both interventions were related to broader program delivery characteristics (e.g., human resource needs and transportation requirements) that are not easily addressed by the addition of SMS. The addition of SMS technology itself introduced new layers of complexity.

Understanding careseeking for child illness in sub-Saharan Africa: a systematic review and conceptual framework based on qualitative research of household recognition and response to child diarrhoea, pneumonia and malaria.

Diarrhoea, pneumonia and malaria are the largest contributors to childhood mortality in sub-Saharan Africa. While supply side efforts to deliver effective and affordable interventions are being scaled up, ensuring timely and appropriate use by caregivers remains a challenge. This systematic review synthesises qualitative evidence on the factors that underpin household recognition and response to child diarrhoea, pneumonia and malaria in sub-Saharan Africa. For this review, we searched six electronic databases, hand searched 12 journals from 1980 to 2010 using key search terms, and solicited expert review. We identified 5104 possible studies and included 112. Study quality was appraised using the Critical Appraisal Skills Program (CASP) tool. We followed a meta-ethnographic approach to synthesise findings according to three main themes: how households understand these illnesses, how social relationships affect recognition and response, and how households act to prevent and treat these illnesses. We synthesise these findings into a conceptual model for understanding household pathways to care and decision making. Factors that influence household careseeking include: cultural beliefs and illness perceptions; perceived illness severity and efficacy of treatment; rural location, gender, household income and cost of treatment. Several studies also emphasise the importance of experimentation, previous experience with health services and habit in shaping household choices. Moving beyond well-known barriers to careseeking and linear models of pathways to care, the review suggests that treatment decision making is a dynamic process characterised by uncertainty and debate, experimentation with multiple and simultaneous treatments, and shifting interpretations of the illness and treatment options, with household decision making hinging on social negotiations with a broad variety of actors and influenced by control over financial resources. The review concludes with research recommendations for tackling remaining gaps in knowledge.

Going beyond the surface: gendered intra-household bargaining as a social determinant of child health and nutrition in low and middle income countries.

A growing body of research highlights the importance of gendered social determinants of child health, such as maternal education and women's status, for mediating child survival. This narrative review of evidence from diverse low and middle-income contexts (covering the period 1970-May 2012) examines the significance of intra-household bargaining power and process as gendered dimensions of child health and nutrition. The findings focus on two main elements of bargaining: the role of women's decision-making power and access to and control over resources; and the importance of household headship, structure and composition. The paper discusses the implications of these findings in the light of lifecycle and intersectional approaches to gender and health. The relative lack of published intervention studies that explicitly consider gendered intra-household bargaining is highlighted. Given the complex mechanisms through which intra-household bargaining shapes child health and nutrition it is critical that efforts to address gender in health and nutrition programming are thoroughly documented and widely shared to promote further learning and action. There is scope to develop links between gender equity initiatives in areas of adult and adolescent health, and child health and nutrition programming. Child health and nutrition interventions will be more effective, equitable and sustainable if they are designed based on gender-sensitive information and continually evaluated from a gender perspective.

Economic evaluation of a combined microfinance and gender training intervention for the prevention of intimate partner violence in rural South Africa.

OBJECTIVE: Assess the cost-effectiveness of an intervention combining microfinance with gender and HIV training for the prevention of intimate partner violence (IPV) in South Africa. METHODS: We performed a cost-effectiveness analysis alongside a cluster-randomized trial. We assessed the cost-effectiveness of the intervention in both the trial and initial scale-up phase. RESULTS: We estimated the cost per DALY gained as US$7688 for the trial phase and US$2307 for the initial scale-up. The findings were sensitive to the statistical uncertainty in effect estimates but otherwise robust to other key assumptions employed in the analysis. CONCLUSIONS: The findings suggest that this combined economic and health intervention was cost-effective in its trial phase and highly cost-effective in scale-up. These estimates are probably conservative, as they do not include the health and development benefits of the intervention beyond IPV reduction.

Promoting critical consciousness and social mobilization in HIV/AIDS programmes: lessons and curricular tools from a South African intervention.

The development of critical consciousness is seen as a key stage in communities increasing levels of dialogue about priority problems and effecting structural change for health. However, relatively little research identifies concrete methods for programmes to build critical consciousness. We examined how a South African structural intervention used critical consciousness as a tool for prevention of intimate partner violence and HIV infection. We collected qualitative data in the form of in-depth interviews with managers, trainers, and participants of the Intervention with Microfinance for AIDS and Gender Equity intervention (IMAGE) in rural South Africa. The data were analysed through a coding structure developed in QSR NVivo. We draw practical lessons from IMAGE to guide other HIV programmes aiming to promoting critical consciousness and social mobilization. This research suggests that specific curricular tools can work towards critical consciousness and that mobilization efforts in future programmes can be strengthened by including individual and collective efforts by participants.

Characteristics of sexual partnerships, not just of individuals, are associated with condom use and recent HIV infection in rural South Africa.

Characteristics of sexual partnerships, as well as those of the individuals involved, might influence the use of condoms and risk of HIV transmission. We set out to identify characteristics of non-spousal sexual partnerships associated with condom use at last sex in the previous year and HIV infection in the previous three years among sexually active young people in rural South Africa. We conducted an analysis of follow-up data (collected in 2004) from a cohort of 14-35-year old men and women recruited to a cluster-randomised trial. Data on 1647 non-spousal sexual partnerships during the previous year were reported in 2004 and analysed alongside new HIV infections over the previous three years among 762 individuals who were HIV-negative in 2001. Structured interviews elicited information on sexual behaviour. HIV serostatus was assessed through oral-fluid ELISA. Condom use at last sex was reported for 615/1647 non-spousal sexual partnerships (37.3%) and was more commonly reported by individuals who were younger, more educated and aware of their HIV status. Condom use was more common in casual partnerships, those where the male partner was younger, where sex was less frequent and where the respondent believed the partner to have other sexual contacts. New HIV infection in the last three years was identified for 87/762 individuals (11.4%) and was more common among females and those out of school. Infection risk was associated with the age of the partners and was less common among individuals reporting less frequent intercourse in the previous year. Characteristics of sexual partnerships, as well as those of individuals, are important determinants of condom use and risk of HIV infection. Male characteristics may be particularly important because of their greater capacity to make decisions about HIV prevention. Established non-spousal sexual partnerships are an increasingly important context for HIV transmission in this setting.

Comprehensive care and HIV prophylaxis after sexual assault in rural South Africa: the Refentse intervention study.

PROBLEM: Although international guidelines specify the central role of the health sector in providing comprehensive care, including HIV post-exposure prophylaxis (PEP), after sexual assault, in both industrialised and developing countries there are many challenges to providing timely and comprehensive services. DESIGN: A nurse driven model of post-rape care was integrated into existing hospital services; the before and after study design evaluated impacts on quality of care, reviewing 334 hospital charts and conducting interviews with 16 service providers and 109 patients. SETTING: 450 bed district hospital in rural South Africa. KEY MEASURES FOR IMPROVEMENT: Quality of care after rape (forensic history and examination, provision of emergency contraception, prophylaxis for sexually transmitted infections, referrals); provision of HIV counselling and testing and provision and completion of full 28 day course of PEP; and service utilisation (number of service providers seen on first visit and number of rape cases presenting to hospital per month). STRATEGIES FOR CHANGE: After completing baseline research, we introduced a five part intervention model, consisting of a sexual violence advisory committee, hospital rape management policy, training workshop for service providers, designated examining room, and community awareness campaigns. Effect of change Existing services were fragmented and of poor quality. After the intervention, there were considerable improvements in clinical history and examination, pregnancy testing, emergency contraception, prophylaxis for sexually transmitted infections; HIV counselling and testing, PEP, trauma counselling, and referrals. Completion of the 28 day course of PEP drugs increased from 20% to 58%. LESSONS LEARNT: It is possible to improve the quality of care after sexual assault, including HIV prophylaxis, within a rural South African hospital at modest cost, using existing staff. With additional training, nurses can become the primary providers of this care.

"They have opened our mouths": increasing women's skills and motivation for sexual communication with young people in rural South Africa.

Communication between parents and young people about sex has been identified as a positive influence on young people's sexual behavior. This article presents findings from South Africa, where a social intervention to reduce levels of HIV and intimate partner violence actively promoted sexual communication between adults and young people. We assessed this component of the program using quantitative and qualitative methods, collecting data through surveys, direct observation, interviews, and focus group discussions. Women participating in intervention activities reported sexual communication with children significantly more often than matched women in the control group (80.3% vs. 49.4%, adjusted risk ratio 1.59 (1.31-1.93). The content of communication with young people also appears to have shifted from vague admonitions about the dangers of sex to concrete messages about reducing risks. The congruence between these findings and existing literature on parent-child sexual communication suggests that conceptual frameworks and programs from developed settings can be adapted effectively for resource-poor contexts.

Can social capital be intentionally generated? a randomized trial from rural South Africa.

While much descriptive research has documented positive associations between social capital and a range of economic, social and health outcomes, there have been few intervention studies to assess whether social capital can be intentionally generated. We conducted an intervention in rural South Africa that combined group-based microfinance with participatory gender and HIV training in an attempt to catalyze changes in solidarity, reciprocity and social group membership as a means to reduce women's vulnerability to intimate partner violence and HIV. A cluster randomized trial was used to assess intervention effects among eight study villages. In this paper, we examined effects on structural and cognitive social capital among 845 participants and age and wealth matched women from households in comparison villages. This was supported by a diverse portfolio of qualitative research. After two years, adjusted effect estimates indicated higher levels of structural and cognitive social capital in the intervention group than the comparison group, although confidence intervals were wide. Qualitative research illustrated the ways in which economic and social gains enhanced participation in social groups, and the positive and negative dynamics that emerged within the program. There were numerous instances where individuals and village loan centres worked to address community concerns, both working through existing social networks, and through the establishment of new partnerships with local leadership structures, police, the health sector and NGOs. This is among the first experimental trials suggesting that social capital can be exogenously strengthened. The implications for community interventions in public health are further explored.

A combined microfinance and training intervention can reduce HIV risk behaviour in young female participants.

OBJECTIVE: To assess effects of a combined microfinance and training intervention on HIV risk behavior among young female participants in rural South Africa. DESIGN: : Secondary analysis of quantitative and qualitative data from a cluster randomized trial, the Intervention with Microfinance for AIDS and Gender Equity study. METHODS: Eight villages were pair-matched and randomly allocated to receive the intervention. At baseline and after 2 years, HIV risk behavior was assessed among female participants aged 14-35 years. Their responses were compared with women of the same age and poverty group from control villages. Intervention effects were calculated using adjusted risk ratios employing village level summaries. Qualitative data collected during the study explored participants' responses to the intervention including HIV risk behavior. RESULTS: After 2 years of follow-up, when compared with controls, young participants had higher levels of HIV-related communication (adjusted risk ratio 1.46, 95% confidence interval 1.01-2.12), were more likely to have accessed voluntary counseling and testing (adjusted risk ratio 1.64, 95% confidence interval 1.06-2.56), and less likely to have had unprotected sex at last intercourse with a nonspousal partner (adjusted risk ratio 0.76, 95% confidence interval 0.60-0.96). Qualitative data suggest a greater acceptance of intrahousehold communication about HIV and sexuality. Although women noted challenges associated with acceptance of condoms by men, increased confidence and skills associated with participation in the intervention supported their introduction in sexual relationships. CONCLUSIONS: In addition to impacts on economic well being, women's empowerment and intimate partner violence, interventions addressing the economic and social vulnerability of women may contribute to reductions in HIV risk behavior.

Is social capital associated with HIV risk in rural South Africa?

The role of social capital in promoting health is now widely debated within international public health. In relation to HIV, the results of previous observational and cross-sectional studies have been mixed. In some settings it has been suggested that high levels of social capital and community cohesion might be protective and facilitate more effective collective responses to the epidemic. In others, group membership has been a risk factor for HIV infection. There have been few attempts to strengthen social capital, particularly in developing countries, and examine its effect on vulnerability to HIV. Employing data from an intervention study, we examined associations between social capital and HIV risk among 1063 14 to 35-year-old male and female residents of 750 poor households from 8 villages in rural Limpopo province, South Africa. We assessed cognitive social capital (CSC) and structural social capital (SSC) separately, and examined associations with numerous aspects of HIV-related psycho-social attributes, risk behavior, prevalence and incidence. Among males, after adjusting for potential confounders, residing in households with greater levels of CSC was linked to lower HIV prevalence and higher levels of condom use. Among females, similar patterns of relationships with CSC were observed. However, while greater SSC was associated with protective psychosocial attributes and risk behavior, it was also associated with higher rates of HIV infection. This work underscores the complex and nuanced relationship between social capital and HIV risk in a rural African context. We suggest that not all social capital is protective or health promotive, and that getting the balance right is critical to informing HIV prevention efforts.

Explaining continued high HIV prevalence in South Africa: socioeconomic factors, HIV incidence and sexual behaviour change among a rural cohort, 2001-2004.

OBJECTIVES: To estimate HIV incidence and explore evidence for changing sexual behaviour over time among men and women belonging to different socioeconomic groups in rural South Africa. DESIGN AND METHODS: A cohort study conducted between 2001 and 2004; 3881 individuals aged 14-35 years enumerated in eight villages were eligible. At least three household visits were made to contact each eligible respondent at both timepoints. Sexual behaviour data were collected in structured, respondent-focused interviews. HIV serostatus was assessed using an oral fluid enzyme-linked immunosorbent assay at each timepoint. RESULTS: Data on sexual behaviour were available from 1967 individuals at both timepoints. A total of 1286 HIV-negative individuals at baseline contributed to the analysis of incidence. HIV incidence was 2.2/100 person-years among men and 4.9/100 person-years in women, among whom it was highest in the least educated group. Median age at first sex was lower among later birth cohorts. A higher number of previously sexually active individuals reported having multiple partners in the past year in 2004 than 2001. Condom use with non-spousal partners increased from 2001 to 2004. Migrant men more often reported multiple partners. Migrant and more educated individuals of both sexes and women from wealthier households reported higher levels of condom use. DISCUSSION: HIV incidence is high in rural South Africa, particularly among women of low education. Some risky sexual behaviours (early sexual debut, having multiple sexual partners) are becoming more common over time. Condom use is increasing. Existing HIV prevention strategies have only been partly effective in generating population-level behavioural change.

Understanding the impact of a microfinance-based intervention on women's empowerment and the reduction of intimate partner violence in South Africa.

OBJECTIVES: We sought to obtain evidence about the scope of women's empowerment and the mechanisms underlying the significant reduction in intimate partner violence documented by the Intervention With Microfinance for AIDS and Gender Equity (IMAGE) cluster-randomized trial in rural South Africa. METHODS: The IMAGE intervention combined a microfinance program with participatory training on understanding HIV infection, gender norms, domestic violence, and sexuality. Outcome measures included past year's experience of intimate partner violence and 9 indicators of women's empowerment. Qualitative data about changes occurring within intimate relationships, loan groups, and the community were also collected. RESULTS: After 2 years, the risk of past-year physical or sexual violence by an intimate partner was reduced by more than half (adjusted risk ratio=0.45; 95% confidence interval=0.23, 0.91). Improvements in all 9 indicators of empowerment were observed. Reductions in violence resulted from a range of responses enabling women to challenge the acceptability of violence, expect and receive better treatment from partners, leave abusive relationships, and raise public awareness about intimate partner violence. CONCLUSIONS: Our findings, both qualitative and quantitative, indicate that economic and social empowerment of women can contribute to reductions in intimate partner violence.

Assessing household wealth in health studies in developing countries: a comparison of participatory wealth ranking and survey techniques from rural South Africa.

BACKGROUND: Accurate tools for assessing household wealth are essential for many health studies in developing countries. Household survey and participatory wealth ranking (PWR) are two approaches to generate data for this purpose. METHODS: A household survey and PWR were conducted among eight villages in rural South Africa. We developed three indicators of household wealth using the data. One indicator used PWR data only, one used principal components analysis to combine data from the survey, while the final indicator used survey data combined in a manner informed by the PWR. We assessed internal consistency of the indices and assessed their level of agreement in ranking household wealth. RESULTS: Food security, asset ownership, housing quality and employment were important indicators of household wealth. PWR, consisting of three independent rankings of 9671 households, showed a high level of internal consistency (intraclass correlation coefficient 0.81, 95% CI 0.79-0.82). Data on 1429 households were available from all three techniques. There was moderate agreement in ranking households into wealth tertiles between the two indicators based on survey data (spearman rho = 0.69, kappa = 0.43), but only limited agreement between these techniques and the PWR data (spearman rho = 0.38 and 0.31, kappa = 0.20 and 0.17). CONCLUSION: Both PWR and household survey can provide a rapid assessment of household wealth. Each technique had strengths and weaknesses. Reasons for differences might include data inaccuracies or limitations in the methods by which information was weighted. Alternatively, the techniques may measure different things. More research is needed to increase the validity of measures of socioeconomic position used in health studies in developing countries.

Effect of a structural intervention for the prevention of intimate-partner violence and HIV in rural South Africa: a cluster randomised trial.

BACKGROUND: HIV infection and intimate-partner violence share a common risk environment in much of southern Africa. The aim of the Intervention with Microfinance for AIDS and Gender Equity (IMAGE) study was to assess a structural intervention that combined a microfinance programme with a gender and HIV training curriculum. METHODS: Villages in the rural Limpopo province of South Africa were pair-matched and randomly allocated to receive the intervention at study onset (intervention group, n=4) or 3 years later (comparison group, n=4). Loans were provided to poor women who enrolled in the intervention group. A participatory learning and action curriculum was integrated into loan meetings, which took place every 2 weeks. Both arms of the trial were divided into three groups: direct programme participants or matched controls (cohort one), randomly selected 14-35-year-old household co-residents (cohort two), and randomly selected community members (cohort three). Primary outcomes were experience of intimate-partner violence--either physical or sexual--in the past 12 months by a spouse or other sexual intimate (cohort one), unprotected sexual intercourse at last occurrence with a non-spousal partner in the past 12 months (cohorts two and three), and HIV incidence (cohort three). Analyses were done on a per-protocol basis. This trial is registered with ClinicalTrials.gov, number NCT00242957. FINDINGS: In cohort one, experience of intimate-partner violence was reduced by 55% (adjusted risk ratio [aRR] 0.45, 95% CI 0.23-0.91; adjusted risk difference -7.3%, -16.2 to 1.5). The intervention did not affect the rate of unprotected sexual intercourse with a non-spousal partner in cohort two (aRR 1.02, 0.85-1.23), and there was no effect on the rate of unprotected sexual intercourse at last occurrence with a non-spousal partner (0.89, 0.66-1.19) or HIV incidence (1.06, 0.66-1.69) in cohort three. INTERPRETATION: A combined microfinance and training intervention can lead to reductions in levels of intimate-partner violence in programme participants. Social and economic development interventions have the potential to alter risk environments for HIV and intimate-partner violence in southern Africa.

Rape and HIV post-exposure prophylaxis: addressing the dual epidemics in South Africa.

In South Africa, a country notable for both a rapidly escalating AIDS epidemic and high levels of sexual violence, the issue of HIV post-exposure prophylaxis (PEP) following rape has recently come to the fore, and a policy supporting provision of PEP has been approved by the national government. This paper compares the conditions for providing PEP in Europe and North America with the conditions faced by two initiatives in South Africa, one serving a primarily rural base, and one urban. It is based on a review of the literature on sexual violence in South Africa and use of PEP following occupational and non-occupational exposure. It incorporates perspectives from in-depth interviews in 2000 with 18 key informants, including survivors of sexual violence, gender and HIV activists, domestic violence NGOs, rape crisis centres, physicians, lawyers, researchers and HIV/AIDS advisors in the Department of Health. The paper argues that given the scientific evidence for PEP, and the nature of the dual epidemics of HIV and sexual violence in South Africa, the public health and social justice rationale for implementing PEP equals and indeed exceeds that put forward in industrialised countries. However, delays in accessing PEP caused by the public justice system and lack of training for service providers constitute significant obstacles to effective implementation. In this respect, provision of PEP presents an opportunity to reform and strengthen existing services for post-rape care and to link attention to the epidemic of sexual violence to HIV/AIDS prevention.
