RESUMEN
BACKGROUND: Malaria-endemic countries distribute long-lasting insecticidal nets (LLINs) through combined channels with ambitious, universal coverage (UC) targets. Kenya has used eight channels with variable results. To inform national decision-makers, this two-arm study compares coverage (effects), costs, cost-effectiveness, and equity of two combinations of LLIN distribution channels in Kenya. METHODS: Two combinations of five delivery channels were compared as 'intervention' and 'control' arms. The intervention arm comprised four channels: community health volunteer (CHV), antenatal and child health clinics (ANCC), social marketing (SM) and commercial outlets (CO). The control arm consisted of the intervention arm channels except mass campaign (MC) replaced CHV. Primary analysis used random sample household survey data, service-provider costs, and voucher or LLIN distribution data to compare between-arm effects, costs, cost-effectiveness, and equity. Secondary analyses compared costs and equity by channel. RESULTS: The multiple distribution channels used in both arms of the study achieved high LLIN ownership and use. The intervention arm had significantly lower reported LLIN use the night before the survey (84·8% [95% CI 83·0-86·4%] versus 89·2% [95% CI 87·8-90·5%], p < 0·0001), higher unit costs ($10·56 versus $7·17), was less cost-effective ($86·44, 95% range $75·77-$102·77 versus $69·20, 95% range $63·66-$77·23) and more inequitable (Concentration index [C.Ind] = 0·076 [95% CI 0·057 to 0·095 versus C.Ind = 0.049 [95% CI 0·030 to 0·067]) than the control arm. Unit cost per LLIN distributed was lowest for MC ($3·10) followed by CHV ($10·81) with both channels being moderately inequitable in favour of least-poor households. CONCLUSION: In line with best practices, the multiple distribution channel model achieved high LLIN ownership and use in this Kenyan study setting. The control-arm combination, which included MC, was the most cost-effective way to increase UC at household level. Mass campaigns, combined with continuous distribution channels, are an effective and cost-effective way to achieve UC in Kenya. The findings are relevant to other countries and donors seeking to optimise LLIN distribution. TRIAL REGISTRATION: The assignment of the intervention was not at the discretion of the investigators; therefore, this study did not require registration.

INTRODUCTION: Chronic cough is a distressing symptom and a common reason for people to seek health care services. It is a symptom that can indicate underlying tuberculosis (TB) and/or chronic airways diseases (CAD) including asthma, chronic obstructive pulmonary disease (COPD) and bronchiectasis. In developing countries including Malawi, provision of diagnostic services and clinical management of CAD is rudimentary, so it is thought that patients make costly and unyielding repeated care-seeking visits. There is, however, a lack of information on cost of illness, both direct and indirect, to patients with chronic cough symptom. Such data are needed to inform policy-makers in making decisions on allocating resources for designing and developing the relevant health care services to address universal coverage programmes for CAD. This paper therefore explores health seeking costs associated with chronic cough and explores information on usage of the coping mechanisms which indicate financial hardship, such as borrowing and selling household assets. METHODS: This economic study was nested within a community-based, population-proportional cross-sectional survey of 15,795 individuals aged 15 years and above, in Dowa and Ntchisi districts. The study sought to identify individuals with symptoms of chronic airways disease whose health records documented at least one of the following diagnoses within the previous year: TB, Asthma, COPD, Bronchitis and Lower Respiratory Tract Infection (LRTI). We interviewed these chronic coughers to collect information on socioeconomic and socio-demographic characteristics, health care utilization, and associated costs of care in 2015. We also collected information on how they funded their health seeking costs. RESULTS: We identified 608 chronic coughers who reported costs in relation to their latest confirmed diagnosis in their hand-held health record. The mean care-seeking cost per patient was US$ 3.9 (95% CI: 3.00-5.03); 2.3 times the average per capita expenditure on health of US$ 1.69. The largest costs were due to transport (US$ 1.4), followed by drugs (US$ 1.3). The costs of non-medical inputs (US$ 2.09) was considerable (52.3%). Nearly a quarter (24.4%) of all the patients reportedly borrowed or/and sold assets/property to finance their healthcare. CCs with COPD and LRTI had 85.6% and 62.0% lower chance of incurring any costs compared with the TB patients and any patients with comorbidity had 2.9 times higher chance to incur any costs than the patients with single disease. COPD, Bronchitis and LRTI patients had 123.9%, 211.4% and 87.9% lower costs than the patients with TB. The patients with comorbidity incurred 53.9% higher costs than those with single disease. CONCLUSIONS: The costs of healthcare per chronic cougher was mainly influenced by the transport and drugs costs. Types of diseases and comorbidity led to significantly different chances of incurring costs as well as difference in magnitude of costs. The costs appeared to be unaffordable for many patients.

INTRODUCTION: Historically, Kenya has used various distribution models for long-lasting insecticide-treated bed nets (LLINs) with variable results in population coverage. The models presently vary widely in scale, target population and strategy. There is limited information to determine the best combination of distribution models, which will lead to sustained high coverage and are operationally efficient and cost-effective. Standardised cost information is needed in combination with programme effectiveness estimates to judge the efficiency of LLIN distribution models and options for improvement in implementing malaria control programmes. The study aims to address the information gap, estimating distribution cost and the effectiveness of different LLIN distribution models, and comparing them in an economic evaluation. METHODS AND ANALYSIS: Evaluation of cost and coverage will be determined for 5 different distribution models in Busia County, an area of perennial malaria transmission in western Kenya. Cost data will be collected retrospectively from health facilities, the Ministry of Health, donors and distributors. Programme-effectiveness data, defined as the number of people with access to an LLIN per 1000 population, will be collected through triangulation of data from a nationally representative, cross-sectional malaria survey, a cross-sectional survey administered to a subsample of beneficiaries in Busia County and LLIN distributors' records. Descriptive statistics and regression analysis will be used for the evaluation. A cost-effectiveness analysis will be performed from a health-systems perspective, and cost-effectiveness ratios will be calculated using bootstrapping techniques. ETHICS AND DISSEMINATION: The study has been evaluated and approved by Kenya Medical Research Institute, Scientific and Ethical Review Unit (SERU number 2997). All participants will provide written informed consent. The findings of this economic evaluation will be disseminated through peer-reviewed publications.

INTRODUCTION: Multidrug-resistant tuberculosis (MDR-TB) poses a serious financial challenge to health systems and patients. The current treatment for patients with MDR-TB takes up to 24â months to complete. Evidence for a shorter regimen which differs from the standard WHO recommended MDR-TB regimen and typically lasts between 9 and 12â months has been reported from Bangladesh. This evaluation aims to assess the economic impact of a shortened regimen on patients and health systems. This evaluation is innovative as it combines patient and health system costs, as well as operational modelling in assessing the impact. METHODS AND ANALYSIS: An economic evaluation nested in a clinical trial with 2 arms will be performed at 4 facilities. The primary outcome measure is incremental cost to the health system of the study regimen compared with the control regimen. Secondary outcome measures are mean incremental costs incurred by patients by treatment outcome; patient costs by category (direct medical costs, transport, food and accommodation costs, and cost of guardians/accompanying persons and lost time); health systems cost by category and drugs; and costs related to serious adverse events. ETHICS AND DISSEMINATION: The study has been evaluated and approved by the Ethics Advisory Group of the International Union Against Tuberculosis and Lung Disease; South African Medical Research Ethics Committee; Wits Health Consortium Protocol Review Committee; University of the Witwatersrand Human Research Ethics Committee; University of Kwazulu-Natal Biomedical Research Ethics Committee; St Peter TB Specialized Hospital Ethical Review Committee; AHRI-ALERT Ethical Review Committee, and all participants will provide written informed consent. The results of the economic evaluation will be published in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: ISRCTN78372190.

BACKGROUND: In developing countries like Malawi, further investigation is rare after patients with chronic cough test negative for tuberculosis. Chronic airways disease has presentations that overlap with tuberculosis. However, chronic airways disease is often unrecognised due to a lack of diagnostic services. Within developing countries, referral systems at primary health care level are weak and patients turn to unskilled informal health providers to seek health care. Delayed diagnosis and treatment of these diseases facilitates increased severity and tuberculosis transmission. The World Health Organisation developed the Practical Approach to Lung Health strategy which has been shown to improve the management of both tuberculosis and chronic airways disease. The guidelines address the need for integrated guidelines for tuberculosis and chronic airways disease. Engaging with informal health providers has been shown to be effective in improving health services uptake. However, it is not known whether engaging community informal health providers would have a positive impact in the implementation of the Practical Approach to Lung Health strategy. We will use a cluster randomised controlled trial to determine the effect of using the two interventions to improve case detection and treatment of patients with tuberculosis and chronic airways disease. METHODS: A three-arm cluster randomised trial design will be used. A primary health centre catchment population will form a cluster, which will be randomly allocated to one of the arms. The first arm personnel will receive the Practical Approach to Lung Health strategy intervention. In addition to this strategy, the second arm personnel will receive training of informal health providers. The third arm is the control. The effect of interventions will be evaluated by community surveys. Data regarding the diagnosis and management of chronic cough will be gathered from primary health centres. DISCUSSION: This trial seeks to determine the effect of Informal Health Provider and Practical Approach to Lung Health interventions on the detection and management of chronic airways disease and tuberculosis at primary care level in Malawi. TRIAL REGISTRATION: The unique identification number for the registry is PACTR201411000910192--21 November 2014.

OBJECTIVE: To assess the cost-effectiveness of community-based practitioner programmes in Ethiopia, Indonesia and Kenya. METHODS: Incremental cost-effectiveness ratios for the three programmes were estimated from a government perspective. Cost data were collected for 2012. Life years gained were estimated based on coverage of reproductive, maternal, neonatal and child health services. For Ethiopia and Kenya, estimates of coverage before and after the implementation of the programme were obtained from empirical studies. For Indonesia, coverage of health service interventions was estimated from routine data. We used the Lives Saved Tool to estimate the number of lives saved from changes in reproductive, maternal, neonatal and child health-service coverage. Gross domestic product per capita was used as the reference willingness-to-pay threshold value. FINDINGS: The estimated incremental cost per life year gained was 82 international dollars ($)in Kenya, $999 in Ethiopia and $3396 in Indonesia. The results were most sensitive to uncertainty in the estimates of life-years gained. Based on the results of probabilistic sensitivity analysis, there was greater than 80% certainty that each programme was cost-effective. CONCLUSION: Community-based approaches are likely to be cost-effective for delivery of some essential health interventions where community-based practitioners operate within an integrated team supported by the health system. Community-based practitioners may be most appropriate in rural poor communities that have limited access to more qualified health professionals. Further research is required to understand which programmatic design features are critical to effectiveness.

BACKGROUND: Chronic airway diseases pose a big challenge to health systems in most developing countries, particularly in Sub-Saharan Africa. A diagnosis for people with chronic or persistent cough is usually delayed because of individual and health system barriers. However, delayed diagnosis and treatment facilitates further transmission, severity of disease with complications and mortality. The objective of this study is to assess the cost-effectiveness of the practical approach to lung health strategy, a patient-centred approach for diagnosis and treatment of common respiratory illnesses in primary healthcare settings, as a means of strengthening health systems to improve the quality of management of respiratory diseases. METHODS/DESIGN: Economic evaluation nested in a cluster randomised controlled trial with three arms will be performed. Measures of effectiveness and costs for all arms of the study will be obtained from the cluster randomised controlled clinical trial. The main outcome measures are a combined rate of major respiratory diseases milestones and process indicators extracted from the practical approach to lung health strategy. For analysis, descriptive as well as regression techniques will be used. A cost-effectiveness analysis will be performed according to intention-to-treat principle and from a societal perspective. Cost-effectiveness ratios will be calculated using bootstrapping techniques. DISCUSSION: We hope to demonstrate the cost-effectiveness of the practical approach to lung health and informal healthcare providers, see an improvement in patients' quality of life, achieve a reduction in the duration and occurrence of episodes and the chronicity of respiratory diseases, and are able to report a decrease in the social cost. If the practical approach to lung health and informal healthcare provider's interventions are cost-effective, they could be scaled up to all primary healthcare centres.

Health insecurity has emerged as a major concern among health policy-makers particularly in low- and middle-income countries (LMICs). It includes the inability to secure adequate healthcare today and the risk of being unable to do so in the future as well as impoverishing healthcare expenditure. The increasing health insecurity among 150 million of the world's poor has moved social protection in health (SPH) to the top of the agenda among health policy-makers globally. This paper aims to provide a debate on the potential of social protection contribution to addressing health insecurity, poverty, and vulnerability brought by healthcare expenditure in low-income countries, to explore the gaps in current and proposed social protection measures in healthcare and provide suggestions on how social protection intervention aimed at addressing health insecurity, poverty, and vulnerability may be effectively implemented.
