RESUMO

OBJECTIVE: To estimate the Brazilian direct and indirect costs of human visceral leishmaniasis (VL) in 2014. METHODS: Cost-of-illness study on the Brazilian public health system and societal perspective. VL cases registered in the Notifiable Diseases Information System in the year of 2014 were considered. Direct medical costs regarding diagnostic, treatment and care provided to patients with VL were estimated through the top-down approach. The indirect costs related to productivity loss due to premature mortality and morbidity were estimated by means of the human-capital method. RESULTS: In 2014, 9895 suspected cases of VL were reported in the Notifiable Diseases Information System, and 3453 were later confirmed. There were 234 patients with Leishmania-HIV coinfection underwent a secondary prophylaxis. The total cost of VL in Brazil was US$ 14 190 701.50 (US$ 14 189 150.10 to 14 199 940.53) that varied according to the sensitivity analysis. The total of direct medical costs corresponded to US$ 1 873 681.96 (US$1 872 130.55 to 1 882 920.99), and the majority of costs was associated with hospitalisation (40%), followed by treatment (22%), and secondary prophylaxis (18%). Productivity loss corresponded to US$ 11 421 683.37 for premature mortality and US$ 895 336.18 for work absence due to hospitalisation by the illness. CONCLUSIONS: VL represents an expensive health problem for the Brazilian public health system and society, mainly because of its productivity loss due to premature mortality. Interventions to reduce VL lethality could have a great impact on decreasing the cost of illness.

RESUMO

Spatial heterogeneity in the incidence of visceral leishmaniasis (VL) is an important aspect to be considered in planning control actions for the disease. The objective of this study was to predict areas at high risk for visceral leishmaniasis (VL) based on socioeconomic indicators and remote sensing data. We applied classification and regression trees to develop and validate prediction models. Performance of the models was assessed by means of sensitivity, specificity and area under the ROC curve. The model developed was able to discriminate 15 subsets of census tracts (CT) with different probabilities of containing CT with high risk of VL occurrence. The model presented, respectively, in the validation and learning samples, sensitivity of 79% and 52%, specificity of 75% and 66%, and area under the ROC curve of 83% and 66%. Considering the complex network of factors involved in the occurrence of VL in urban areas, the results of this study showed that the development of a predictive model for VL might be feasible and useful for guiding interventions against the disease, but it is still a challenge as demonstrated by the unsatisfactory predictive performance of the model developed.

RESUMO

BACKGROUND: In the context of limited health care budgets in countries where Neglected Tropical Diseases (NTDs) are endemic, scaling up disease control interventions entails the setting of priorities. However, solutions based solely on cost-effectiveness analyses may lead to biased and insufficiently justified priorities. OBJECTIVES: The objectives of this paper are to 1) demonstrate how a range of equity concerns can be used to identify feasible priority setting criteria, 2) show how these criteria can be fed into a multi-criteria decision-making matrix, and 3) discuss the conditions under which this decision-making procedure should be carried out in a real-world decision-making context. METHODS: This paper draws on elements from theories of decision analysis and ethical theories of fair resource allocation. We explore six typical NTD interventions by employing a modified multi-criteria decision analysis model with predefined criteria, drawn from a priority setting guide under development by the WHO. To identify relevant evidence for the six chosen interventions, we searched the PubMed and Cochrane databases. DISCUSSION: Our in vitro multi-criteria decision analysis suggested that case management for visceral leishmaniasis should be given a higher priority than mass campaigns to prevent soil-transmitted helminthic infections. This seems to contradict current health care priorities and recommendations in the literature. We also consider procedural conditions that should be met in a contextualised decision-making process and we stress the limitations of this study exercise. CONCLUSION: By exploring how several criteria relevant to the multi-facetted characteristics of NTDs can be taken into account simultaneously, we are able to suggest how improved priority settings among NTDs can be realised.

RESUMO

BACKGROUND & OBJECTIVES: The burden of visceral leishmaniasis (VL) in Nepal, as in other developing countries, falls disproportionately upon the rural poor. Promoting use of outpatient (OP) care, an alternative to inpatient (IP) care has long been advocated to reduce cost of care in both the demand and supply sides as substitution of relatively cheaper resources for expensive resources in the production of health care services. The paper aims to assess the intensity of demand for VL care and explore possibilities of the substitutability or complementation patterns between OP care and IP care of VL. METHODS: In order to explore the possibility of substitute (or complement) of OP care for IP care, we exploited the ordinary least squared method by utilizing recently collected data from the VL endemic districts of Nepal. The sample size represented > 25% of the population of VL of the country. The paper measured the sensitivity analysis of demand for OP and IP cares using appropriate demand models. RESULTS: The coefficients of demand models gave negative relationship between quantity demanded for health care and their prices. It is plausible that OP price has strong power than IP price to determine the respective quantity demanded for health care. As expected, income has negative sign, but not significant that means income has no effect on determining the demand for health care because VL is a disease of poor. CONCLUSION: Recently, improvements in treatment and diagnostic techniques suggest a substitute of OP care for IP care; however, the OP and IP cares are complements due to behavioural factors.

RESUMO

OBJECTIVE: In 2009, a random survey was conducted in Muzaffarpur district to document the clinical outcomes of visceral leishmaniasis patients (VL) treated by the public health care system in 2008, to assess the effectiveness of miltefosine against VL. We analysed the operational feasibility and cost of such periodic random surveys as compared with health facility-based routine monitoring. METHODS: A random sample of 150 patients was drawn from registers kept at Primary Health Care centres. Patient records were examined, and the patients were located at their residence. Patients and physicians were interviewed with the help of two specifically designed questionnaires by a team of one supervisor, one physician and one field worker. Costs incurred during this survey were properly documented, and vehicle log books maintained for analysis. RESULTS: Hundred and 39 (76.7%) of the patients could be located. Eleven patients were not traceable. Per patient, follow-up cost was US$ 15.51 and on average 2.27 patients could be visited per team-day. Human resource involvement constituted 75% of the total cost whereas involvement of physician costs 51% of the total cost. CONCLUSION: A random survey to document clinical outcomes is costly and labour intensive but gives probably the most accurate information on drug effectiveness. A health service-based retrospective cohort reporting system modelled on the monitoring system developed by tuberculosis programmes could be a better alternative. Involvement of community health workers in such monitoring would offer the additional advantage of treatment supervision and support.

RESUMO

BACKGROUND: Effective case identification strategies are fundamental to capturing the remaining visceral leishmaniasis (VL) cases in India. To inform government strategies to reach and sustain elimination benchmarks, this study presents costs of active- and passive- case detection (ACD and PCD) strategies used in India's most VL-endemic state, Bihar, with a focus on programme outcomes stratified by district-level incidence. METHODS: Expenditure analysis was complemented by onsite micro-costing to compare the cost of PCD in hospitals alongside index case-based ACD and a combination of blanket (house-to-house) and camp ACD from January to December 2018. From the provider's perspective, a cost analysis evaluated the overall programme cost of each activity, the cost per case detected, and the cost of scaling up ACD. RESULTS: During 2018, index case-based ACD, blanket and camp ACD, and PCD reported 1,497, 131, and 1,983 VL-positive cases at a unit cost of $522.81, $4,186.81, and $246.79, respectively. In high endemic districts, more VL cases were identified through PCD while in meso- and low-endemic districts more cases were identified through ACD. The cost of scaling up ACD to identify 3,000 additional cases ranged from $1.6-4 million, depending on the extent to which blanket and camp ACD was relied upon. CONCLUSION: Cost per VL test conducted (rather than VL-positive case identified) may be a better metric estimating unit costs to scale up ACD in Bihar. As more VL cases were identified in meso-and low-endemic districts through ACD than PCD, health authorities in India should consider bolstering ACD in these areas. Blanket and camp ACD identified fewer cases at a higher unit cost than index case-based ACD. However, the value of detecting additional VL cases early outweighs long-term costs for reaching and sustaining VL elimination benchmarks in India.

RESUMO

BACKGROUND: In Brazil, case-fatality from visceral leishmaniasis (VL) is high and characterized by wide differences between the various political-economic units, the federated units (FUs). This study was designed to investigate the association between factors at the both FU and individual levels with the risk of dying from VL, after analysing the temporal trend and the spatial dependency for VL case-fatality. METHODOLOGY: The analysis was based on individual and aggregated data of the Reportable Disease Information System-SINAN (Brazilian Ministry of Health). The temporal and spatial distributions of the VL case-fatality between 2007 and 2017 (27 FUs as unit of analysis) were considered together with the individual characteristics and many other variables at the FU level (socioeconomic, demographic, access to health and epidemiological indicators) in a mixed effects models or multilevel modeling, assuming a binomial outcome distribution (death from VL). FINDINGS: A linear increasing temporal tendency (4%/year) for VL case-fatality was observed between 2007 and 2017. There was no similarity between the case-fatality rates of neighboring FUs (non-significant spatial term), although these rates were heterogeneous in this spatial scale of analysis. In addition to the known individual risk factors age, female gender, disease's severity, bacterial co-infection and disease duration, low level schooling and unavailability of emergency beds and health professionals (the last two only in univariate analysis) were identified as possibly related to VL death risk. Lower VL incidence was also associated to VL case-fatality, suggesting that unfamiliarity with the disease may delay appropriate medical management: VL patients with fatal outcome were notified and had VL treatment started 6 and 3 days later, respectively, in relation to VL cured patients. Access to garbage collection, marker of social and economic development, seems to be protective against the risk of dying from VL. Part of the observed VL case-fatality variability in Brazil could not be explained by the studied variables, suggesting that factors linked to the intra FU environment may be involved. CONCLUSIONS: This study aimed to identify epidemiological conditions and others related to access to the health system possibly linked to VL case-fatality, pointing out new prognostic determinants subject to intervention.

RESUMO

PURPOSE OF REVIEW: Several attempts have been made to combine drugs for treating visceral leishmaniasis, but only recently have effective drugs become available and combinations been tested systematically. RECENT FINDINGS: Sequential treatments with liposomal amphotericin B followed by miltefosine or paromomycin (as short as 7 days), as well as the concomitant administration of miltefosine and paromomycin (for 10 days) are very effective in India (>95%). Sodium stibogluconate plus paromomycin for 17 days is more than 90% effective in East Africa. The shortened combination regimens are cost-effective in India. No combination has been tested so far in Brazil, Nepal and Bangladesh, although studies may be expected in the near future. No cost-effectiveness analysis has been done as yet outside India. SUMMARY: There is evidence of high efficacy and benefits with sequential and co-administration treatments in India. More studies are needed in other endemic areas. Introducing combinations and scaling up their use will be challenging. Experience acquired with malaria may be useful. Proper monitoring of use and effects (efficacy and safety) will be required. Currently there are no options for fixed-dose combination treatments for leishmaniasis.

RESUMO

OBJECTIVE: In 2005 a visceral leishmaniasis (VL) elimination initiative was launched on the Indian subcontinent, with early diagnosis based on a rapid diagnostic test and treatment with the oral drug miltefosine as its main strategy. Several recent studies have signaled underreporting of VL cases in the region. Information on treatment outcomes is scanty. Our aim was to document VL case management by the primary health care services in India. METHODS: We took a random sample of all VL patients registered in rural primary health care (PHC) facilities of Muzaffarpur district, Bihar, India during 2008. Patients were traced at home for an interview and their records were reviewed. We recorded patient and doctor delay, treatment regimens, treatment outcomes and costs incurred by patients. RESULTS: We could review records of all 150 patients sampled and interview 139 patients or their guardian. Most patients (81%) had first presented to unqualified practitioners; median delay before reaching the appropriate primary healthcare facility was 40 days (IQR 31-59 days). Existing networks of village health workers were under-used. 48% of VL patients were treated with antimonials; 40% of those needed a second treatment course. Median direct expenditure by patients was 4000 rupees per episode (IQR 2695-5563 rupees), equivalent to almost 2 months of household income. CONCLUSION: In 2008 still critical flaws remained in VL case management in the primary health care services in Bihar: obsolete use of antimonials with high failure rates and long patient delay. To meet the target of the VL elimination, more active case detection strategies are needed, and village health worker networks could be more involved. Costs to patients remain an obstacle to early case finding.

RESUMO

OBJECTIVE: To determine the cost of kala-azar (KA) to patients in Bihar, India. METHOD: A semi-structured questionnaire was used to collect costs of illness--direct (medical; non-medical) and indirect costs (work days lost). After screening the community known to be endemic for visceral leishmaniasis (VL), households (HHs) with VL were recruited which reported a case of KA who received treatment between September 2005 and September 2006. The total costs were calculated as a summation of individual costs category. Medians were estimated for the total and for each of the cost categories. RESULT: Data from 171 HHs and 183 patients revealed that median age of patients with KA was 18; 59% were men; 33% were employed; household size was 7; household median monthly income was $38. The median total costs per patient were $127, equal to >3 months of income, of which medical care comprised $83 (provider fees $13, medicines $50, diagnostics $9, hospital stay $30); and food and transport comprised $33. Patients also lost almost 2 weeks of work time during illness and even after recovery. CONCLUSION: Despite provision of free/subsidized medicines, diagnostics, and hospital stay at public and Non-Governmental Organization facilities, the impoverished HHs of Bihar with a case of KA incur high expenditures. Easier access to, and more use of free public health services, plus innovative health financing schemes, are urgently required.

RESUMO

OBJECTIVE: To estimate the economic burden of visceral leishmaniasis (VL) on the rural population of one VL endemic district of Bihar, the state with 85% of India's cases. METHODS: Using a survey of a stratified multistage sampling of 15 178 households with 214 individuals with VL in the previous 12 months, the study provides data on VL treatment expenditures, financing and days of work lost in the context of overall household expenditures, income sources and assets. RESULTS: Median household expenditures on VL treatment represent, on average, 11% of annual household expenditures and an estimated 7 months of an individual's income at the daily wage in rural Bihar. With 87% of households forced to take out loans to finance disease costs, VL can contribute to a spiral of increasing poverty. The current pattern of VL treatment, with multiple visits and treatments for a single episode of illness, significantly increases the economic burden on the household. CONCLUSION: India's National Elimination Program to make effective treatments accessible to the rural poor, if combined with expanded efforts to improve timely access to diagnosis by conducting rapid diagnostic tests closer to the community (and mobilizing the rural population to seek effective treatment earlier), can reduce VL's economic burden on India's rural households.

RESUMO

Several tropical diseases that are essentially poverty-related have recently gained more attention under the label of 'neglected tropical diseases' or NTD. It is estimated that over 1000 million people currently suffer from one or more NTD. Here, the socio-economic aspects of two NTD - human African trypanosomiasis and human visceral leishmaniasis - are reviewed. Both of these diseases affect the poorest of the poor in endemic countries, cause considerable direct and indirect costs (even though the national control programmes tend to provide free care) and push affected households deeper into poverty.

RESUMO

CONTEXT: Visceral leishmaniasis (VL) is a severe and potentially fatal infection caused by the trypanosome parasite Leishmania sp. Over 90% of reported cases occur in India, Bangladesh, Nepal, Sudan, and Brazil, affecting mainly impoverished individuals and creating a significant economic burden through direct and indirect costs of treatment. OBJECTIVES: To identify the direct and indirect costs of VL treatment, compare these costs to household income, and identify the barriers to treatment in each of the five VL-endemic countries. METHODS: Articles obtained through PubMed (US National Library of Medicine), EMBASE, and Cochrane Library were selected for relevance to VL treatment, costs for all forms of amphotericin B, miltefosine, paromomycin, and antimony compounds, and healthcare costs in India, Bangladesh, Nepal, Brazil, and Sudan. Healthcare statistics were obtained from the World Health Organization Statistical Information System, Médecins Sans Frontieres, and each country's national health ministry. RESULTS: Per capita GDP, per capita GNI, cost of drugs, and hospitalization expenses differ by up to 10-fold in each of the five countries where VL is hyperendemic, resulting in unequal barriers to treatment. We found that the cost of specific drugs influences the choice of therapy. CONCLUSIONS: Poverty and VL treatment-related costs cause potential limitations in the provision of full and efficacious treatment, which may result in further dissemination of the disease. Effective nonparenteral antileishmania drugs would provide a significant advantage in reducing the barriers to VL treatment.

RESUMO

BACKGROUND & OBJECTIVES: Visceral leishmaniasis, locally known as kala-azar (KA) has been considered as a major public health problem in Bangladesh, India and Nepal that affects 100,000 people per year with 147 million people at risk. Elimination of infectious disease is an ultimate goal of the public health system, therefore, the efforts have recently gained momentum from various organizations and governments to expand KA interventions in the endemic countries. The paper aims to estimate discounted net benefits and internal rate of return (IRR) to evaluate the economic feasibility for elimination of KA by utilizing available secondary information. METHODS: Cross-sectional data were collected from different sources to estimate societal costs of and benefits from KA interventions with a 13-year project period. Total costs are estimated based on the unit cost of inputs used for interventions. The benefits are derived from productivity change and resources saved due to reduction of KA incidence. Net benefits and IRRs are estimated based on standard procedures used in the field of economics, subsequently the sensitivity analysis is conducted. RESULTS: A total discounted net benefit of KA intervention is Nepalese Rupees (NRs) 65,287 million with 35% IRR. The result suggests that for every rupee invested in KA intervention at present will yield NRs 71 in future. The regional benefits from the interventions will be greater than the sum of benefits gained by the individual country due to its nature of public goods. CONCLUSION: Elimination of KA is a good investment opportunity for the Government and international partners involved in the health sector.

RESUMO

Visceral leishmaniasis (VL) is one of the world's worst parasitic killers, second only to Malaria, claiming thousands of lives every year. More than three fifths of the world's VL cases occur in the Indian state of Bihar alone. While some research has been conducted with emphasis on the effects of climatic variables on the VL incidence rate, rigorous analysis of the effects of socio-economic variables is still lacking. In this paper a regression model is developed that describes the relationship between VL incidence rate and a variety of socio-economic factors. It uses data from 2005 and explains 92% of the observed variance. In addition, a stepwise regression model is also used to identify the most important factors that facilitate the prevalence of the VL disease. A discussion on how to most effectively distribute Bihar's limited resources on various control measures to decrease the incidence of VL is also presented.

RESUMO

OBJECTIVES: To estimate the budget impact of the expansion of liposomal amphotericin B use for all confirmed cases of visceral leishmaniasis (VL) in Brazil. Currently, the first-line medicine for VL treatment is meglumine antimoniate. Liposomal amphotericin B is indicated only for patients with a greater risk of severity by the disease. METHODS: The analysis was performed from the perspective of the Brazilian public healthcare system over 3 years, considering the following 2 scenarios: the reference scenario with the current recommendations for VL treatment and the alternative scenario based on the use of liposomal amphotericin B for all patients. A diffusion rate of 60% was used in the first year, 80% in the second year, and 100% in the third year. The epidemiological parameters used in the analysis came from the Notifiable Diseases Information System and from a clinical trial that evaluated the efficacy and safety of medicines for the treatment of VL in the country. The costs were related to the treatment of VL and to hospital and outpatient care. RESULTS: In the reference scenario, the total cost for treatment of the 3453 VL confirmed cases in 2014 was $1 447 611.75. The incremental budget impact with the use of liposomal amphotericin B for all the VL confirmed cases was $299 646.43 in the third year. CONCLUSIONS: The analysis presented will support the decision process for the use and expansion of liposomal amphotericin B for all VL confirmed cases in Brazil.

RESUMO

Human visceral leishmaniasis (VL) is a severe and potentially fatal parasitic disease if not correctly diagnosed and treated. Brazil is one of the three countries most endemic for VL and, like most countries affected by this disease, has a large budget constraint for the incorporation of new health technologies. Although different diagnostic tests for VL are currently available in the country, economic studies evaluating diagnostic kits are scarce. The objective of this study was to conduct a cost-effectiveness analysis of the nine available diagnostic tests for human VL in HIV-infected and uninfected patients in Brazil. The perspective of analysis was the Brazilian public health system, and the outcome of interest was "cases diagnosed correctly". The costs of the tests were estimated using the microcosting technique, and comparisons were performed with decision trees. Sensitivity analyses were explored applying variations in cost and effectiveness values. For VL diagnosis among HIV-uninfected patients, using blood samples for the rapid tests (RDTs), the noncommercial direct agglutination test (DAT-LPC) and IT-LEISH were cost-effective tests compared with the baseline OnSite test, but they presented different incremental cost-effectiveness ratios (ICER) of US$7.04 and US$ 205.40, respectively. Among HIV-infected patients, DAT-LPC was the most cost-effective diagnostic test. Comparisons among the tests with the same methodology, based on the low ICER values, revealed that IT-LEISH was the most cost-effective test among the RDTs and the Ridascreen Leishmania Ab among the ELISA tests. These results confirm that cost-effectiveness analyses can provide useful information to support the incorporation of new health technologies within a known scenario and willingness to pay threshold. It was observed that tests based on the same methodologies presented different cost-effectiveness ratios for the same group of patients and that different tests should be recommended for different patient groups. DAT-LPC was an important cost-effective strategy for all patients, requiring minimum laboratorial infrastructure, and IT-LEISH was the cost-effective test for VL screening in HIV-uninfected patients. IT-LEISH and DAT-LPC have complementary profiles and should both be provided by the Brazilian health system.

RESUMO

Visceral leishmaniasis (VL) is an important zoonosis in Brazil. Dogs are considered the main domestic reservoirs of the disease in the country; hence, control measures are focused on these reservoirs. Despite efforts to prevent and control VL, important reductions in disease prevalence and incidence have not been identified, stimulating the development and application of new strategies. The choice and implementation of new control strategies can benefit from the application of mathematical models that allow the simulation of different strategies in different scenarios. Selecting the best strategy to be implemented is also supported by cost-effectiveness studies. Here we used the results of a mathematical model in which scenarios, including isolated use of the vaccine and insecticide-impregnated collar (IIC), both at different coverage rates, were simulated to conduct a cost-effectiveness study. The costs were calculated for each scenario considering a simulation period of four years. Collar application in both infected and non-infected animals was the most cost-effective strategy. For example, to reduce the prevalence in humans and dogs by approximately 70%, the costs ranged from $250,000 and $550,000 for the IICs and vaccination, respectively. Even in the scenario with 40% loss/replacement of IICs, this measure was more advantageous in terms of cost-effectiveness than vaccination. If the vaccine were applied with culling of seropositive tested dogs, then the measure became more effective with a reduced cost compared with the vaccine alone. The use of the three first consecutive vaccine doses had the greatest impact on the cost of the vaccination strategy. The advantage of using IICs is that there is no need for a prior diagnosis, unlike vaccination, reducing costs and facilitating implementation. The present study aims to contribute to strategies to reduce hosts infected with VL by reducing public expenditure.

RESUMO

BACKGROUND: Co-infection with Visceral Leishmaniasis (commonly known as Kala Azar, KA) and Human Immunodeficiency Virus (HIV) is increasingly being diagnosed among patients in Bihar. This qualitative study is the first assessment of self-reported quality of life among patients co-infected with KA-HIV in the Asian context. METHODS: We conducted semi-structured, in-depth interviews and adopted an inductive thematic analysis to generate evidence on the quality of life of patients co-infected with KA and HIV. Patients were purposively sampled until saturation was attained. RESULTS: We found that patients highly valued income or livelihood potential and health as indicators of a good quality life, and routinely went into debt accessing care in the private setup. This was due to perceptions of poor quality of care in the government setup and a lack of knowledge regarding available government services at the district level. KA symptoms were often misdiagnosed in the private sector as seasonal fever, while care providers found it difficult to disentangle the clinical symptoms of KA and HIV; hence, patients presented late to district hospitals. Patients perceived a high level of stigma, largely due to their HIV status, and routinely reported that HIV had "destroyed" their life. CONCLUSIONS: Inadequate social support and referral pathways that were not conducive to patient needs negatively impacted patients' quality of life. The dual burden of poverty interacting with the severity and chronicity of KA-HIV co-infection means financial support, increased community engagement, and collaborative decision making are crucial for co-infected patients. Increased provider awareness of co-infection and effective stigma-reduction interventions should be integrated to ensure that appropriate and effective access to care is possible for this vulnerable population. A sustainable long-term strategy requires a people-centered approach wherein the perceptions and life circumstances of patients are taken into account in the medical decision making process.
