Self-help: What future role in health care for low and middle-income countries?

In the debate on 'Third options' for health care delivery in low- and middle-income countries it is proposed that self-help should play a larger role. Self-help is expected to contribute towards improving population health outcomes and reducing government health care expenditure. We review scope and limitations of self-help groups in Europe and South Asia and assess their potential role in health care within the context of health sector reform. Self-help groups are voluntary unions of peers, formed for mutual assistance in accomplishing a health-related purpose. In Europe, self-help groups developed out of dissatisfaction with a de-personalised health care system. They successfully complement existing social and health services but cannot be instrumentalized to improve health outcomes while reducing health expenditure. In South Asia, with its hierarchical society, instrumental approaches towards self-help prevail in Non-governmental Organizations and government. The utility of this approach is limited as self-help groups are unlikely to be sustainable and effective when steered from outside. Self-help groups are typical for individualistic societies with developed health care systems – they are less suitable for hierarchical societies with unmet demand for regulated health care. We conclude that self-help groups can help to achieve some degree of synergy between health care providers and users but cannot be prescribed to partially replace government health services in low-income countries, thereby reducing health care expenditure and ensuring equity in health care

Verbal autopsy interpretation: a comparative analysis of the InterVA model versus physician review in determining causes of death in the Nairobi DSS

<p>Abstract</p> <p>Background</p> <p>Developing countries generally lack complete vital registration systems that can produce cause of death information for health planning in their populations. As an alternative, verbal autopsy (VA) - the process of interviewing family members or caregivers on the circumstances leading to death - is often used by Demographic Surveillance Systems to generate cause of death data. Physician review (PR) is the most common method of interpreting VA, but this method is a time- and resource-intensive process and is liable to produce inconsistent results. The aim of this paper is to explore how a computer-based probabilistic model, InterVA, performs in comparison with PR in interpreting VA data in the Nairobi Urban Health and Demographic Surveillance System (NUHDSS).</p> <p>Methods</p> <p>Between August 2002 and December 2008, a total of 1,823 VA interviews were reviewed by physicians in the NUHDSS. Data on these interviews were entered into the InterVA model for interpretation. Cause-specific mortality fractions were then derived from the cause of death data generated by the physicians and by the model. We then estimated the level of agreement between both methods using Kappa statistics.</p> <p>Results</p> <p>The level of agreement between individual causes of death assigned by both methods was only 35% (κ = 0.27, 95% CI: 0.25 - 0.30). However, the patterns of mortality as determined by both methods showed a high burden of infectious diseases, including HIV/AIDS, tuberculosis, and pneumonia, in the study population. These mortality patterns are consistent with existing knowledge on the burden of disease in underdeveloped communities in Africa.</p> <p>Conclusions</p> <p>The InterVA model showed promising results as a community-level tool for generating cause of death data from VAs. We recommend further refinement to the model, its adaptation to suit local contexts, and its continued validation with more extensive data from different settings.</p

The health and well-being of older people in Nairobi's slums

Background: Globally, it is estimated that people aged 60 and over constitute more than 11% of the population, with the corresponding proportion in developing countries being 8%. Rapid urbanisation in sub-Saharan Africa (SSA), fuelled in part by rural&#x2013;urban migration and a devastating HIV/AIDS epidemic, has altered the status of older people in many SSA societies. Few studies have, however, looked at the health of older people in SSA. This study aims to describe the health and well-being of older people in two Nairobi slums. Methods: Data were collected from residents of the areas covered by the Nairobi Urban Health and Demographic Surveillance System (NUHDSS) aged 50 years and over by 1 October 2006. Health status was assessed using the short SAGE (Study on Global AGEing and Adult Health) form. Mean WHO Quality of Life (WHOQoL) and a composite health score were computed and binary variables generated using the median as the cut-off. Logistic regression was used to determine factors associated with poor quality of life (QoL) and poor health status. Results: Out of 2,696 older people resident in the NUHDSS surveillance area during the study period, data were collected on 2,072. The majority of respondents were male, aged 50&#x2013;60 years. The mean WHOQoL score was 71.3 (SD 6.7) and mean composite health score was 70.6 (SD 13.9). Males had significantly better QoL and health status than females and older respondents had worse outcomes than younger ones. Sex, age, education level and marital status were significantly associated with QoL, while slum of residence was significantly associated with health status. Conclusion: The study adds to the literature on health and well-being of older people in SSA, especially those in urban informal settlements. Further studies are needed to validate the methods used for assessing health status and to provide comparisons from other settings. Health and Demographic Surveillance Systems have the potential to conduct such studies and to evaluate health and well-being over time

Correlates for cardiovascular diseases among diabetic/hypertensive patients attending outreach clinics in two Nairobi slums, Kenya

Introduction:&nbsp;cardiovascular diseases (CVD) are the leading cause of death in the world. Over 80% of CVD related deaths occur in low- and middle-income countries (LMICs). Diabetes and hypertension, whose prevalence in Kenya is on the rise, are major risk factors for CVD. Despite this, studies indicate that awareness on the management of risk factors for CVD among diabetic/hypertensive patients in African populations is generally low. The aim of the study was to determine the risk factors for CVD among diabetic and/or hypertensive patients attending diabetes and hypertension management clinics in Korogocho and Viwandani slums of Nairobi. Methods:&nbsp;data were collected using questionnaires administered to 206 diabetic/hypertensive patients attending the clinics between July 2010 and February 2011. A review of these patients' medical records was done to determine the history of CVD outcomes such as hypertensive heart diseases, stroke and peripheral arterial diseases. Results:&nbsp;majority (66.5%) of the study participants were females mainly in the 51-65 age category. The study findings revealed that 73 (33.4%) respondents had CVD outcomes. In addition, 41.8% of the respondents were not aware of the causes of diabetes/hypertension. Age category 51-65 years had the highest (43.8%) number of respondents with CVD. Sex of the respondents and awareness of the link between hypertension and CVD were significantly associated with CVD outcomes (p&lt;0.05) among the respondents. Conclusion:&nbsp;measures to improve awareness levels among patients at high risk of CVD outcomes are needed to complement other measures to reduce CVD risk among such patients

Assessment of cardiovascular risk in a slum population in Kenya : use of World Health Organisation/International Society of Hypertension (WHO/ISH) risk prediction charts - secondary analyses of a household survey

Objectives Although cardiovascular disease (CVD) is of growing importance in low- and middle-income countries (LMICs), there are conflicting views regarding CVD as a major public health problem for the urban poor, including those living in slums. We examine multivariable risk prediction in a slum population and assess the number of cardiovascular related deaths within 10 years of application of the tool. Setting We use data from the Nairobi Urban Health and Demographic Surveillance System (NUHDSS) population (residents of two slum communities) between May 2008 and April 2009. Design This is a secondary data analysis from a cross-sectional survey. We use the WHO/International Society of Hypertension (WHO/ISH) cardiovascular risk prediction tool to examine 10-year risk of major CVD events in a slum population. CVD deaths in the cohort, reported up until June 2018 and identified through verbal autopsy are also presented. Participants 3063 men and women aged over 40 years with complete data for variables needed for the WHO/ISH risk prediction tool were eligible to take part. Results The majority of study members (2895, 94.5%) were predicted to have ‘low’ risk (20% were identified as dying of CVD. Conclusions This study shows that there is a low risk profile of CVD in this slum population in Nairobi, Kenya, in comparison to results from application of multivariable risk prediction tools in other LMIC populations. This has implications for health service planning in these contexts

Strengthening health system governance using health facility service charters: a mixed methods assessment of community experiences and perceptions in a district in Kenya.

BACKGROUND: Enhancing accountability in health systems is increasingly emphasised as crucial for improving the nature and quality of health service delivery worldwide and particularly in developing countries. Accountability mechanisms include, among others, health facilities committees, suggestion boxes, facility and patient charters. However, there is a dearth of information regarding the nature of and factors that influence the performance of accountability mechanisms, especially in developing countries. We examine community members' experiences of one such accountability mechanism, the health facility charter in Kericho District, Kenya. METHODS: A household survey was conducted in 2011 among 1,024 respondents (36% male, 64% female) aged 17 years and above stratified by health facility catchment area, situated in a division in Kericho District. In addition, sixteen focus group discussions were conducted with health facility users in the four health facility catchment areas. Quantitative data were analysed through frequency distributions and cross-tabulations. Qualitative data were transcribed and analysed using a thematic approach. RESULTS: The majority (65%) of household survey respondents had seen their local facility service charter, 84% of whom had read the information on the charter. Of these, 83% found the charter to be useful or very useful. According to the respondents, the charters provided useful information about the services offered and their costs, gave users a voice to curb potential overcharging and helped users plan their medical expenses before receiving the service. However, community members cited several challenges with using the charters: non-adherence to charter provisions by health workers; illegibility and language issues; lack of expenditure records; lack of time to read and understand them, often due to pressures around queuing; and socio-cultural limitations. CONCLUSION: Findings from this study suggest that improving the compliance of health facilities in districts across Kenya with regard to the implementation of the facility service charter is critical for accountability and community satisfaction with service delivery. To improve the compliance of health facilities, attention needs to be focused on mechanisms that help enforce official guidelines, address capacity gaps, and enhance public awareness of the charters and their use

Analysis of non-communicable disease prevention policies in Kenya

Preparation of this report would not have been possible without funding support from the International Development Research Center (IDRC), Canada, channeled through the African Population and Research Center (APHRC) as part of the project, Analysis of Non-communicable Disease Prevention Policies in Africa (ANPPA).This Kenyan case study report is part of a broader study examining the existence of noncommunicable disease prevention policies and the extent to which multi-sectoral approaches were applied in the policy development and implementation processes in five sub-Saharan African countries: Kenya, South Africa, Cameroon, Nigeria, and Malawi. In particular, the study focused on policies addressing the World Health Organization (WHO) “best buy” interventions for non-communicable disease (NCD) prevention. These interventions address the four major NCD risk factors, namely: tobacco use, harmful alcohol consumption, unhealthy diet, and physical inactivity

Antiretroviral therapy (ART) provision has been a mainstay of HIV treatment efforts globally. In Kenya, the government started ART provision in 2003 with significantly scale-up after 2006. This study aims to demonstrate changes in population-level HIV mortality in two high HIV prevalence slums in Nairobi with respect to the initiation and subsequent scale-up of the national ART program. METHODS: We used data from 2070 deaths of people aged 15-54 years that occurred between 2003 and 2010 in a population of about 72,000 individuals living in two slums covered by the Nairobi Urban Health and Demographic Surveillance System. Only deaths for which verbal autopsy was conducted were included in the study. We divided the analysis into two time periods: the "early" period (2003-2006) which coincides with the initiation of ART program in Kenya, and the "late" period (2007-2010) which coincides with the scale up of the program nationally. We calculated the mortality rate per 1000 person years by gender and age for both periods. Poisson regression was used to predict the risk of HIV mortality in the two periods while controlling for age and gender. RESULTS: Overall, HIV mortality declined significantly from 2.5 per 1,000 person years in the early period to 1.7 per 1,000 person years in the late period. The risk of dying from HIV was 53 percent less in the late period compared to the period before, controlling for age and gender. Women experienced a decline in HIV mortality between the two periods that was more than double that of men. At the same time, the risk of non-HIV mortality did not change significantly between the two time periods. CONCLUSIONS: Population-level HIV mortality in Nairobi's slums was significantly lower in the approximate period coinciding with the scale-up of ART provision in Kenya. However, further studies that incorporate ART coverage data in mortality estimates are needed. Such information will enhance our understanding of the full impact of ART scale-up in reducing adult mortality among marginalized slum populations in Kenya
