Abstract
BACKGROUND In Brazil, since 2005, the Ministry of Health requires Health Economic Evaluation (HEE) of vaccines for introduction into the National Immunization Program. OBJECTIVES To describe and analyze the full HEE on vaccines conducted in Brazil from 1980 to 2013. METHODS Systematic review of the literature. We searched multiple databases. Two researchers independently selected the studies and extracted the data. The methodological quality of individual studies was evaluated using CHEERS items. RESULTS Twenty studies were reviewed. The most evaluated vaccines were pneumococcal (25%) and HPV (15%). The most used types of HEE were cost-effectiveness analysis (45%) and cost-utility analysis (20%). The research question and compared strategies were stated in all 20 studies and the target population was clear in 95%. Nevertheless, many studies did not inform the perspective of analysis or data sources. CONCLUSIONS HEE of vaccines in Brazil has increased since 2008. However, the studies still have methodological deficiencies.

Abstract
In this article, we comment on the main features of infectious diseases in Brazil in the last 50 years, highlighting how much of this path Revista de Saúde Pública could portray. From 1967 to 2016, 1,335 articles focusing on infectious diseases were published in Revista de Saúde Pública. Although the proportion of articles on the topic have decreased from about 50.0% to 15.0%, its notability remained and reflected the growing complexity of the research required for its control. It is noteworthy that studies design and analysis strategies progressively became more sophisticated, following the great development of epidemiology in Brazil in the recent decades. Thus, the journal has followed the success of public health interventions that permitted to control or eliminate numerous infectious diseases - which were responsible, in the past, for high rates of morbidity and mortality -, and also followed the reemergence of diseases already controlled and the emergence of until then unknown diseases, with a strong impact on the Brazilian population, establishing a little predictable and very challenging path. RESUMO Neste artigo, comentamos as principais características das doenças infecciosas no Brasil, nos últimos 50 anos, destacando o quanto a Revista de Saúde Pública conseguiu capturar essa trajetória. De 1967 a 2016, foram publicados 1.335 artigos na Revista de Saúde Pública com foco em doenças infecciosas. Ainda que a proporção de artigos sobre esse tema tenha declinado de cerca de 50,0% para 15,0%, seu destaque se manteve e refletiu a crescente complexidade das pesquisas necessárias para o seu controle. Nota-se que os desenhos dos estudos e as estratégias de análise ganharam progressivamente maior sofisticação, acompanhando o grande desenvolvimento da epidemiologia no Brasil, nas últimas décadas. Assim, foi registrado não apenas o sucesso de intervenções de saúde pública que permitiram o controle ou a eliminação de inúmeras doenças infecciosas responsáveis, no passado, por elevadas taxas de morbimortalidade, como também a reemergência de males já controlados e o surgimento de doenças até então desconhecidas, com forte impacto na população brasileira, desenhando uma trajetória pouco previsível e muito desafiadora.

[PMID: 27595779 PMCID: PMC5011357 DOI: 10.1186/s12879-016-1802-x] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2015] [Accepted: 08/23/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND One of the main goals of the post-2015 global tuberculosis (TB) strategy is that no families affected by TB face catastrophic costs. We revised an existing TB patient cost measurement tool to specifically also measure multi-drug resistant (MDR) TB patients' costs and applied it in Ethiopia, Indonesia and Kazakhstan. METHODS Through structured interviews with TB and MDR-TB patients in different stages of treatment, we collected data on the direct (out of pocket) and indirect (loss of income) costs of patients and their families related to the diagnosis and treatment of TB and MDR-TB. Direct costs included costs for hospitalization, follow-up tests, transport costs for health care visits, and food supplements. Calculation of indirect costs was based on time needed for diagnosis and treatment. Costs were extrapolated over the patient's total treatment phase. RESULTS In total 406 MDR-TB patients and 197 other TB patients were included in the survey: 169 MDR-TB patients and 25 other TB patients in Ethiopia; 143 MDR-TB patients and 118 TB patients in Indonesia; and 94 MDR-TB patients and 54 other TB patients in Kazakhstan. Total costs for diagnosis and current treatment episode for TB patients were estimated to be USD 260 in Ethiopia, USD 169 in Indonesia, and USD 929 in Kazakhstan, compared to USD 1838, USD 2342, and USD 3125 for MDR-TB patients, respectively. These costs represented 0.82-4.6 months of pre-treatment household income for TB patients and 9.3-24.9 months for MDR-TB patients. Importantly, 38-92 % reported income loss and 26-76 % of TB patients lost their jobs due to (MDR) TB illness, further aggravating the financial burden. CONCLUSIONS The financial burden of MDR-TB is alarming, although all TB patients experienced substantial socioeconomic impact of the disease. If the patient is the breadwinner of the family, the combination of lost income and extra costs is generally catastrophic. Therefore, it should be a priority of the government to relieve the financial burden based on the cost mitigation options identified.

Shortened first-line TB treatment in Brazil: potential cost savings for patients and health services. BMC Health Serv Res 2016; 16:27. [PMID: 26800677 PMCID: PMC4722708 DOI: 10.1186/s12913-016-1269-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2015] [Accepted: 01/12/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Shortened treatment regimens for tuberculosis are under development to improve treatment outcomes and reduce costs. We estimated potential savings from a societal perspective in Brazil following the introduction of a hypothetical four-month regimen for tuberculosis treatment. METHODS Data were gathered in ten randomly selected health facilities in Rio de Janeiro. Health service costs were estimated using an ingredient approach. Patient costs were estimated from a questionnaire administered to 126 patients. Costs per visits and per case treated were analysed according to the type of therapy: self-administered treatment (SAT), community- and facility-directly observed treatment (community-DOT, facility-DOT). RESULTS During the last 2 months of treatment, the largest savings could be expected for community-DOT; on average USD 17,351-18,203 and USD 43,660-45,856 (bottom-up and top-down estimates) per clinic. Savings to patients could also be expected as the median (interquartile range) patient-related costs during the two last months were USD 108 (13-291), USD 93 (36-239) and USD 11 (7-126), respectively for SAT, facility-DOT and community-DOT. CONCLUSION Introducing a four-month regimen may result in significant cost savings for both the health service and patients, especially the poorest. In particular, a community-DOT strategy, including treatment at home, could maximise health services savings while limiting patient costs. Our cost estimates are likely to be conservative because a 4-month regimen could hypothetically increase the proportion of patients cured by reducing the number of patients defaulting and we did not include the possible cost benefits from the subsequent prevention of costs due to downstream transmission averted and rapid clinical improvement with less side effects in the last two months.

Abstract
BACKGROUND Novel tuberculosis (TB) drugs and the need to treat drug-resistant tuberculosis (DR-TB) are likely to bring about substantial transformations in TB treatment in coming years. An evidence base for cost and cost-effectiveness analyses of these developments is needed. OBJECTIVE Our objective was to perform a review of papers assessing provider-incurred as well as patient-incurred costs of treating both drug-susceptible (DS) and multidrug-resistant (MDR)-TB. METHODS Five databases (EMBASE, Medline, the National Health Service Economic Evaluation Database, the Cost-Effectiveness Analysis Registry, and Latin American and Caribbean Health Services Literature) were searched for cost and economic evaluation full-text papers containing primary DS-TB and MDR-TB treatment cost data published in peer-reviewed journals between January 1990 and February 2015. No language restrictions were set. The search terms were a combination of 'tuberculosis', 'multidrug-resistant tuberculosis', 'cost', and 'treatment'. In the selected papers, study methods and characteristics, quality indicators and costs were extracted into summary tables according to pre-defined criteria. Results were analysed according to country income groups and for provider costs, patient costs and productivity losses. All values were converted to $US, year 2014 values, so that studies could be compared. RESULTS We selected 71 treatment cost papers on DS-TB only, ten papers on MDR-TB only and nine papers that included both DS-TB and MDR-TB. These papers provided evidence on the costs of treating DS-TB and MDR-TB in 50 and 16 countries, respectively. In 31 % of the papers, only provider costs were included; 26 % included only patient-incurred costs, and the remaining 43 % estimated costs incurred by both. From the provider perspective, mean DS-TB treatment costs per patient were US$14,659 in high-income countries (HICs), US$840 in upper middle-income countries (UMICs), US$273 in lower middle-income (LMICs), and US$258 in low-income countries (LICs), showing a strong positive correlation. The respective costs for treating MDR-TB were US$83,365, US$5284, US$6313 and US$1218. Costs incurred by patients when seeking treatment for DS-TB accounted for an additional 3 % of the provider costs in HICs. A greater burden was seen in the other income groups, increasing the costs of DS-TB treatment by 72 % in UMICs, 60 % in LICs and 31 % in LMICs. When provider costs, patient costs and productivity losses were combined, productivity losses accounted for 16 % in HICs, 29 % in UMICs, 40 % in LMICs and 38 % in LICs. CONCLUSION Cost data for MDR-TB treatment are limited, and the variation in delivery mechanisms, as well as the rapidly evolving diagnosis and treatment regimens, means that it is essential to increase the number of studies assessing the cost from both provider and patient perspectives. There is substantial evidence available on the costs of DS-TB treatment from all regions of the world. The patient-incurred costs illustrate that the financial burden of illness is relatively greater for patients in poorer countries without universal healthcare coverage.

Abstract
BACKGROUND Even when tuberculosis (TB) treatment is free, hidden costs incurred by patients and their households (TB-affected households) may worsen poverty and health. Extreme TB-associated costs have been termed "catastrophic" but are poorly defined. We studied TB-affected households' hidden costs and their association with adverse TB outcome to create a clinically relevant definition of catastrophic costs. METHODS AND FINDINGS From 26 October 2002 to 30 November 2009, TB patients (n = 876, 11% with multi-drug-resistant [MDR] TB) and healthy controls (n = 487) were recruited to a prospective cohort study in shantytowns in Lima, Peru. Patients were interviewed prior to and every 2-4 wk throughout treatment, recording direct (household expenses) and indirect (lost income) TB-related costs. Costs were expressed as a proportion of the household's annual income. In poorer households, costs were lower but constituted a higher proportion of the household's annual income: 27% (95% CI = 20%-43%) in the least-poor houses versus 48% (95% CI = 36%-50%) in the poorest. Adverse TB outcome was defined as death, treatment abandonment or treatment failure during therapy, or recurrence within 2 y. 23% (166/725) of patients with a defined treatment outcome had an adverse outcome. Total costs ≥20% of household annual income was defined as catastrophic because this threshold was most strongly associated with adverse TB outcome. Catastrophic costs were incurred by 345 households (39%). Having MDR TB was associated with a higher likelihood of incurring catastrophic costs (54% [95% CI = 43%-61%] versus 38% [95% CI = 34%-41%], p<0.003). Adverse outcome was independently associated with MDR TB (odds ratio [OR] = 8.4 [95% CI = 4.7-15], p<0.001), previous TB (OR = 2.1 [95% CI = 1.3-3.5], p = 0.005), days too unwell to work pre-treatment (OR = 1.01 [95% CI = 1.00-1.01], p = 0.02), and catastrophic costs (OR = 1.7 [95% CI = 1.1-2.6], p = 0.01). The adjusted population attributable fraction of adverse outcomes explained by catastrophic costs was 18% (95% CI = 6.9%-28%), similar to that of MDR TB (20% [95% CI = 14%-25%]). Sensitivity analyses demonstrated that existing catastrophic costs thresholds (≥10% or ≥15% of household annual income) were not associated with adverse outcome in our setting. Study limitations included not measuring certain "dis-saving" variables (including selling household items) and gathering only 6 mo of costs-specific follow-up data for MDR TB patients. CONCLUSIONS Despite free TB care, having TB disease was expensive for impoverished TB patients in Peru. Incurring higher relative costs was associated with adverse TB outcome. The population attributable fraction indicated that catastrophic costs and MDR TB were associated with similar proportions of adverse outcomes. Thus TB is a socioeconomic as well as infectious problem, and TB control interventions should address both the economic and clinical aspects of this disease.

Abstract
In order to inform the development of appropriate strategies to improve financial risk protection, we conducted a systematic literature review of the financial burden of tuberculosis (TB) faced by patients and affected families. The mean total costs ranged from $55 to $8198, with an unweighted average of $847. On average, 20% (range 0-62%) of the total cost was due to direct medical costs, 20% (0-84%) to direct non-medical costs, and 60% (16-94%) to income loss. Half of the total cost was incurred before TB treatment. On average, the total cost was equivalent to 58% (range 5-306%) of reported annual individual and 39% (4-148%) of reported household income. Cost as percentage of income was particularly high among poor people and those with multidrug-resistant TB. Commonly reported coping mechanisms included taking a loan and selling household items. The total cost of TB for patients can be catastrophic. Income loss often constitutes the largest financial risk for patients. Apart from ensuring that healthcare services are fairly financed and delivered in a way that minimises direct and indirect costs, there is a need to ensure that TB patients and affected families receive appropriate income replacement and other social protection interventions.

Abstract
A tuberculose, definida por alguns como a 'calamidade negligenciada, é ainda um importante problema de saúde pública. Para tentar melhorar os resultados no seu enfrentamento, as ações foram descentralizadas para a Atenção Primária à Saúde (APS), o que vem demandando uma nova orientação na Estratégia de Saúde da Família (ESF). Esta pesquisa teve como objetivo analisar a evolução da Estratégia de Saúde da Família (ESF) no município de Curitiba entre os anos de 2000 a 2009 e seus reflexos sobre os casos de Tuberculose. Como metodologia utilizou-se o estudo Ecológico tipo agregado de base territorial longitudinal de séries temporais. A coleta de dados foi realizada no período de outubro de 2010 a julho de 2011. Como principais resultados verificou-se um aumento expressivo de 127,63% no número de Equipes de Saúde da Família, com um aumento da cobertura em 76,28%. Existiu também uma preocupação com relação à capacitação continuada destas equipes o que repercutiu de forma positiva no aumento de exames para diagnóstico realizado, redução do número de casos novos, redução da proporção de abandono do tratamento e da taxa de mortalidade relacionada a tuberculose. Pelo estudo realizado percebe-se uma correção no direcionamento das ações de controle da Tuberculose no município de Curitiba.

Abstract
This study analyzed the limitations and strengths of the Directly Observed Treatment Short-Course (DOTS) for tuberculosis from the perspective of patients and healthcare providers in a Technical Health Supervision unit in the city of São Paulo, SP, Brazil. Four patients and 17 healthcare providers from nine Primary Care Units were interviewed from April to June 2006, after signing free and informed consent forms. The reports were decoded according to the speech analysis technique. The Theory of the Social Determination of the Health-Disease Process was adopted as the theoretical framework. The strengths were: establishment of bonds between healthcare providers and patients and the introduction of incentives, which promotes treatment adherence. Limitations included: restricted involvement of DOTS' healthcare providers and reconciling patients' working hours with supervision. Treatment adherence goes beyond the biological sphere and healthcare providers should acknowledge patients' needs that go beyond the supervision of medication taken.

Abstract
O objetivo do presente estudo foi analisar como a prevalência e a distribuição da cárie dentária influenciam o tamanho da amostra em levantamentos epidemiológicos, e os custos para sua realização. Foram utilizados dados de levantamentos realizados em escolares de 12 anos em Bauru nos anos de 1976, 1984, 1990, 1994 e 2001, e em Piracicaba nos anos de 2001 e 2005. Os tamanhos amostrais foram dimensionados considerando-se a média e o desvio padrão obtidos, fixando-se erro amostral em 1%, 2%, 5% e 10%. Os custos foram estimados considerando material permanente, de consumo e recursos humanos. Verificou-se aumento no tamanho das amostras em ambos os municípios, variando de 119 em 1976 para 1.118 em 2001 em Bauru, e de 954 em 2001 para 1.252 em 2005 em Piracicaba, considerando-se um erro amostral de 10%. Considerando-se diferentes erros amostrais, verificou-se o custo para o levantamento, sendo que o mesmo depende do quanto o pesquisador se permite errar em relação ao verdadeiro valor da média da população. Conclui-se que a diminuição da prevalência da cárie dentária determinou o aumento no tamanho das amostras e a elevação dos custos para realização dos levantamentos.

Abstract
BACKGROUND Neonatal BCG vaccination is part of routine vaccination schedules in many developing countries; vaccination at school age has not been assessed in trials in low-income and middle-income countries. Catch-up BCG vaccination of school-age children who missed neonatal BCG vaccination could be indicated if it confers protection and is cost-effective. We did a cluster-randomised trial (BCG REVAC) to estimate the effectiveness (efficacy given in routine settings) of school-age vaccination. METHODS We assessed the effectiveness of BCG vaccination in school-age children (aged 7-14 years) with unknown tuberculin status who did not receive neonatal BCG vaccination (subpopulation of the BCG REVAC cluster-randomised trial), between July, 1997, and June, 2006, in Salvador, Brazil, and between January, 1999, and December, 2007, in Manaus, Brazil. 763 schools were randomly assigned into BCG vaccination group or a not-vaccinated control group. Neither allocation nor intervention was concealed. Incidence of tuberculosis was the primary outcome. Cases were identified via the Brazilian Tuberculosis Control Programme. Study staff were masked to vaccination status when identified cases were linked to the study population. We estimated cost-effectiveness in Salvador by comparison of the cost for vaccination to prevent one case of tuberculosis (censored at 9 years) with the average cost of treating one case of tuberculosis. Analysis of all included children was by intention to treat. For calculation of the incidence rate we used generalised estimating equations and correlated observations over time. FINDINGS We randomly assigned 20,622 children from 385 schools to the BCG vaccination group and 18,507 children from 365 schools to the control group. The crude incidence of tuberculosis was 54·9 (95% CI 45·3-66·7) per 100,000 person-years in the BCG vaccination group and 72·7 (62·8-86·8) per 100,000 person-years in the control group. The overall vaccine effectiveness of a first BCG vaccination at school age was 25% (3-43%). In Salvador, where vaccine effectiveness was 34% (8-53%), vaccination of 381 children would prevent one case of tuberculosis and was cheaper than treatment. The frequency of adverse events was very low with only one axillary lymphadenitis and one ulcer greater than 1 cm in 11,980 BCG vaccinations. INTERPRETATION Vaccination of school-age children without previous tuberculin testing can reduce the incidence of tuberculosis and could reduce the costs of tuberculosis control. Restriction of BCG vaccination to the first year of life is not in the best interests of the public nor of programmes for tuberculosis control.

Abstract
OBJECTIVE To characterize the profile of patients with pulmonary tuberculosis (PTB) in the city of Santos, Brazil, according to biological, environmental and institutional factors. METHODS Descriptive study, using the TB surveillance database, including patients with PTB, aged 15 years or older, residing in the city of Santos and whose treatment was initiated between 2000 and 2004. RESULTS We identified 2,176 cases, of which 481 presented a history of TB. Of those 481 patients, 29.3% were cured, and 70.7% abandoned treatment. In 61.6% of the cases, the diagnosis was confirmed by sputum smear microscopy, whereas it was confirmed based on clinical and radiological criteria in 33.8%; 69.0% were male; and 69.5% were between 20 and 49 years of age. There were 732 hospitalizations, and the mean length of hospital stay was 32 days (first hospitalization). The prevalence of alcoholism, diabetes and TB/HIV coinfection was, respectively, 11.7%, 8.2% and 16.2%. The prevalence of TB/HIV coinfection decreased from 20.7% to 12.9% during the study period. The treatment outcome was cure, abandonment, death from TB and death attributed to TB/HIV coinfection in 71.0%, 12.1%, 3.9% and 2.5%, respectively. The directly observed treatment, short-course (DOTS) was adopted in 63.4% of cases, and there were no significant differences between DOTS and the conventional treatment approach in terms of outcomes (p > 0.05). The mean annual incidence of PTB was 127.9/100,000 population (range: 72.8-272.92/100,000 population, varying by region). The mean annual mortality rate for PTB was 6.9/100,000 population. CONCLUSIONS In areas hyperendemic for TB, DOTS should be prioritized for groups at greater risk of treatment abandonment or death, and the investigation of TB contacts should be intensified.

Abstract
Background Two TB control strategies appropriate for South Asia (a community-based DOTS [CBD] strategy and a family-based DOTS [FBD] strategy) have been shown to be effective in Nepal in meeting the global target for the proportion of registered patients successfully treated. Here we estimate the costs and cost-effectiveness of the two strategies. This information is essential to allow meaningful comparisons between these and other strategies and will contribute to the small but growing body of knowledge on the costs and cost-effectiveness of different approaches to TB control. Methods In 2001–2, costs relating to TB diagnosis and care were collected for each strategy. Structured and semi-structured questionnaires were used to collect costs from health facility records and a sample of 10 patients in each of 10 districts, 3 using CBD and 2 using FBD. The data collected included costs to the health care system and social costs (including opportunity costs) incurred by patients and their supervisors. The cost-effectiveness of each strategy was estimated. Results Total recurrent costs per patient using the CBD and FBD strategies were US$76.2 and US$84.1 respectively. The social costs incurred by patients and their supervisors represent more than a third of total recurrent costs under each strategy (37% and 35% respectively). The CBD strategy was more cost-effective than the FBD strategy: recurrent costs per successful treatment were US$91.8 and US$102.2 respectively. Discussion Although the CBD strategy was more cost-effective than the FBD strategy in the study context, the estimates of cost-effectiveness were sensitive to relatively small changes in underlying costs and treatment outcomes. Even using these relatively patient-friendly approaches to DOTS, social costs can represent a significant financial burden for TB patients.

Abstract
O objetivo deste estudo foi avaliar custos de implantação e manutenção da assistência odontológica no setor público. Os custos foram atualizados/depreciados de acordo com a vida útil e considerados na perspectiva do serviço e da sociedade. Os resultados mostraram que, para o serviço, o custo total de implantação de uma unidade odontológica com sete consultórios foi de R$ 860.643,67 no primeiro ano e R$ 545.419,23 para manutenção, sendo clínica geral a especialidade mais cara. Para a sociedade, o custo total foi de R$ 990.065,06 (implantação) e R$ 668.369,55 (manutenção) e a especialidade mais cara foi prevenção. Custos de capital representaram um pequeno percentual dos custos de uma unidade odontológica, entretanto, deveriam ser considerados, pois podem modificar os resultados. Devido ao alto custo, intervenções preventivo-promocionais realizadas no ambiente clínico não deveriam ser recomendadas, devendo ser substituídas por ações populacionais amplas e de menor custo, uma vez que valores consideráveis necessitam ser desembolsados pela população de baixa renda para participar de programas públicos gratuitos.

Abstract
BACKGROUND Recent tobacco smoking has been identified as a risk factor for developing tuberculosis, and two studies which have investigated its association with relapse of tuberculosis after completion of treatment had conflicting results (and did not control for confounding). The objective of this study was to investigate risk factors for tuberculosis relapse, with emphasis on smoking. METHODS A cohort of newly diagnosed TB cases was followed up from their discharge after completion of treatment (in 2001-2003) until October 2006 and relapses of tuberculosis ascertained during that period. A case of relapse was defined as a patient who started a second treatment during the follow up. RESULTS Smoking (OR 2.53, 95% CI 1.23-5.21) and living in an area where the family health program was not implemented (OR 3.61, 95% CI 1.46-8.93) were found to be independently associated with relapse of tuberculosis. CONCLUSIONS Our results establish that smoking is associated with relapse of tuberculosis even after adjustment for the socioeconomic variables. Smoking cessation support should be incorporated in the strategies to improve effectiveness of Tuberculosis Control Programs.

Costs of a successful public-private partnership for TB control in an urban setting in Nepal. BMC Public Health 2007; 7:84. [PMID: 17511864 PMCID: PMC1888703 DOI: 10.1186/1471-2458-7-84] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2006] [Accepted: 05/18/2007] [Indexed: 11/29/2022] Open
Abstract
Background In South Asia a large number of patients seek treatment for TB from private practitioners (PPs), and there is increasing international interest in involving PPs in TB control. To evaluate the feasibility, effectiveness and costs of public-private partnerships (PPPs) for TB control, a PPP was developed in Lalitpur municipality, Nepal, where it is estimated that 50% of patients with TB are managed in the private sector. From the clinical perspective the PPP was shown to be effective. The aim of this paper is to assess and report on the costs involved in the PPP scheme. Methods The approach to costing took a comprehensive view, with inclusion of costs not only incurred by health facilities but also social costs borne by patients and their escorts. Semi-structured questionnaires and guided interviews were used to collect start-up and recurrent costs for the scheme. Results Overall costs for treating a TB patient under the PPP scheme averaged US$89.60. Start-up costs per patient represented 12% of the total budget. Half of recurrent costs were incurred by patients and their escorts, with institutional costs representing most of the rest. Female patients tended to spend more and patients referred from the private sector had the highest reported costs. Conclusion Treating TB patients in the PPP scheme had a low additional cost, while doubling the case notification rate and maintaining a high success rate. Costs incurred by patients and their escorts were the largest contributors to the overall total. This suggests a focus for follow-up studies and for cost-minimisation strategies.

Abstract
Background Asthma is one of the most common chronic diseases and a major economical burden to families and health systems. Whereas efficacy of current therapeutical options has been clearly established, cost-effectiveness analysis of public health interventions for asthma control are scarce. Methods 81 patients with severe asthma (12–75 years) joining a programme in a reference clinic providing free asthma medication were asked retrospectively about costs and events in the previous 12 months. During 12 months after joining the programme, information on direct and indirect costs, asthma control by lung function, symptoms and quality of life were collected. The information obtained was used to estimate cost-effectiveness of the intervention as compared to usual public health asthma management. Sensitivity analysis was conducted. Results 64 patients concluded the study. During the 12-months follow-up within the programme, patients had 5 fewer days of hospitalization and 68 fewer visits to emergency/non scheduled medical visits per year, on average. Asthma control scores improved by 50% and quality of life by 74%. The annual saving in public resources was US$387 per patient. Family annual income increased US$512, and family costs were reduced by US$733. Conclusion A programme for control of severe asthma in a developing country can reduce morbidity, improve quality of life and save resources from the health system and patients families.
