A community-based cluster randomized controlled trial of "directly observed home-based daily iron therapy" in lowering prevalence of anemia in rural women and adolescent girls.

In a community-based cluster randomized controlled trial, we randomly assigned clusters of anemic women and adolescent girls to either "directly observed home-based daily iron therapy" (DOHBIT; n = 524 in 16 villages) or unsupervised self-treatment at home (n = 535 in 16 villages) for a period of 90 days. Those in the DOHBIT group, when compared with those in the unsupervised self-treatment group, had significantly lower relative risk (RR) of anemia (16.8% vs 35.3%, RR = 0.47 [95% confidence interval (CI) = 0.33-0.65]; P < .0001), higher hemoglobin (Hb) rise of ≥2 g/dL (70.2% vs 42.2%, RR = 1.56 [95% CI = 1.31-1.87]; P <.0001), and nonsignificant trend for lower side effects (3.5% vs 6.7%, RR = 0.49 [95% CI = 0.22-1.08; P < .08) on intention-to-treat analyses. On linear mixed model analysis, the subjects in the intervention group demonstrated higher mean Hb levels (13.01 vs 12.32 g/dL; P < .0001) and higher adherence to iron therapy (93% vs 60%; P < .0001). DOHBIT is effective in lowering the prevalence of anemia in rural women and adolescent girls.

[Impact of social risk factors on treatment outcome in patients with culture positive pulmonary tuberculosis (CPPTB)]. / Wplyw czynników spolecznych na wyniki leczenia chorych na gruzlice pluc potwierdzona bakteriologicznie.

INTRODUCTION: The aim of the study was to evaluate the impact of social risk factors on treatment outcome among culturepositive patients treated for active pulmonary tuberculosis in three separate districts - Warsaw, Gdansk and Siedlce - in years 1995 and 2000. MATERIAL AND METHODS: We retrospectively reviewed medical records of patients who were notified in 1995 and 2000 and were treated in hospitals and dispensaries. Alcohol abuse and homelessness were recognized as risk factors associated with tuberculosis and nonadherence to treatment. Treatment outcome was evaluated using treatment indicators defined by the World Health Organisation: cured, treatment completed, treatment defaulted, treatment failure and other results of treatment. RESULTS: Seven hundred and eight patients with culture positive pulmonary tuberculosis were included (373 in 1995 and 335 in 2000). There were 85 patients with risk factors in 1995 and 101 patients in 2000. 80 of participants in 1995 and 69 in 2000 abused alcohol, 5 and 32 were classified as homeless, respectively. Among alcohol abusers treatment success rates according to the WHO definition (either bacteriologic cured or treatment completed) were 45.1% in 1995 and 53.6% in 2000. Among patients not abusing alcohol treatment success rates were 63.8% and 54.1%, respectively. The differences were statistically significant (p = 0.005 in 1995 and p = 0.0186 in 2000). In 1995 forty percent of homeless patients had succeeded treatment, while the rate of treatment success among non-homeless was 60%. Because of small number included in homeless group the difference was not statistically significant (p = 0.6532). In 2000 treatment success rate among homeless participants was 25% and among non-homeless - 57.1%, which was highly statistically significant (p = 0.001). CONCLUSION: Alcohol abuse and homelessness were associated with bad treatment outcome among patients with pulmonary tuberculosis. Interventions to improve treatment adherence in patients considered to be at risk for default are necessary.

Desempenho da atenção básica no controle da tuberculose / Performance of primary healthcare services in tuberculosis control

OBJETIVO: Analisar o acesso ao tratamento para tuberculose em serviços de saúde vinculados ao Programa Saúde da Família e em ambulatório de referência. MÉTODOS: Foi realizado estudo do tipo inquérito descritivo, em 2007, com 106 pacientes que receberam tratamento para tuberculose no período de julho/2006 a agosto/2007 em Campina Grande, PB, vinculados ao Programa Saúde da Família (PSF) e em ambulatório de referência. Para avaliação de serviços de saúde, foi utilizado o instrumento Primary Care Assessment Tool, validado e adaptado para atenção à tuberculose no Brasil. As principais variáveis analisadas se referiam a locomoção e distância ao serviço e supervisão dos doentes. RESULTADOS: Dos 106 doentes, 83,9% realizaram tratamento auto-administrado e 16,0% tratamento supervisionado. Os indicadores das unidades PSF e ambulatório de referência, considerados semelhantes (p>0,05), foram: 65,1% "perder o turno de trabalho para consultar"; 65,0% "utilizar o transporte motorizado"; 50,0% "sempre pagar pelo transporte motorizado" e 69,0% não fazer o "tratamento em unidades de saúde perto do seu domicílio". Os indicadores "utilizar transporte motorizado", "pagar pelo transporte para consultar", "fazer tratamento perto de casa" foram estatisticamente diferentes (p<0,05) entre os serviços. Os coeficientes alfa de Cronbach não padronizados e padronizados foram, respectivamente, 0,7275 e 0,7075, com base nos oito itens do questionário. CONCLUSÕES: Apesar de o município ter 85 equipes de PSF, o tratamento supervisionado foi incorporado por poucos. Embora o tratamento da tuberculose seja disponibilizado pelo serviço público de saúde, ainda representa um custo econômico para o paciente em função da necessidade de deslocamento até o serviço de saúde, bem como a perda do turno de trabalho para ser consultado.

OBJECTIVE: To assess the access to tuberculosis treatment in healthcare services with Programa Saúde da Família (PSF - Family Health Program) and at a reference outpatient clinic. METHODS: A descriptive inquiry was carried out in 2007 with 106 patients who received tuberculosis treatment through the PSF or the reference outpatient clinic in Campina Grande, Northeastern Brazil, from July 2006 to August 2007. To assess the health services, the instrument Primary Care Assessment Tool was used, validated and adapted to assess tuberculosis care in Brazil. The main variables analyzed referred to the transportation and distance to the service and patients' supervision. RESULTS: Of the 106 patients, 83.9% performed self-administered treatment and 16.0% received supervised treatment. The indicators from the PSF units and from the reference outpatient clinic that were similar (p>0.05) were: 65.1% "losing half work day to attend the medical visit"; 65.0% "having to use motorized transport"; 50.0% "always having to pay for motorized transport"; and 69.0% "not receiving treatment at healthcare units near home". The indicators "using motorized transport", "paying for transport to attend the medical visit" and "receiving treatment near home" were statistically different (p<0.05) between the services. Standardized and non-standardized Cronbach's alpha coefficients were, respectively, 0.7275 and 0.7075, based on the eight items of the questionnaire. CONCLUSIONS: Although the city has 85 PSF teams, supervised treatment was carried out by few health workers. Although the tuberculosis treatment is offered by the public health service, it still represents a cost to the patients, due to the distance to the healthcare service and losing half work day in order to attend medical visits.

Tuberculosis case management and treatment outcome: assessment of the effectiveness of Public-Private Mix of tuberculosis programme in Kaduna State, Nigeria.

BACKGROUND: In an effort to increase tuberculosis (TB) case detection, the Kaduna State TB program in Nigeria started Public-Private Mix (PPM DOTS) in 2002. This study assessed and compared the TB case management practices and treatment outcomes of the public and private health facilities involved in the TB program. METHODS: A comparative cross-sectional descriptive study was carried out in 5 private and 10 public health facilities providing TB services for at least two years in the four Local Governments Areas in Kaduna State where both public and private health facilities are involved in the TB program. The heads of the health facilities were interviewed and case notes of all the 492 TB patients registered in these facilities between January 2003 and December 2004 reviewed. RESULTS: Except for the lower use of sputum microscopy for diagnosis, adherence to national TB treatment guidelines was high in both private and public health facilities. The private health facilities significantly saw more TB patients, an average of 51 patients per health facility compared to 23 patients in the public health facilities. There was better completion of records in the public health facilities while patient contact screening was very low in both public and private health facilities, 13.1% and 12.2% respectively. The treatment success rate was higher among patients managed in the private health facilities (83.7%) compared to 78.6% in the public health facilities. CONCLUSION: Private health facilities adhere to national guidelines had higher TB patient case load and better treatment outcome than public health facilities in Kaduna State. PPM-DOTS should be scaled-up and consolidated.

[Treatment outcomes in culture positive pulmonary tuberculosis]. / Wyniki leczenia chorych na gruzlice pluc potwierdzona bakteriologicznie.

INTRODUCTION: The aim of the study was to evaluate treatment outcomes in sputum culture positive patients with tuberculosis in three Polish provinces (Warsaw, Gdansk and Siedlce Provinces) in 1995 and again in 2000. We also assessed whether the implementation of the Directly Observed Therapy Short Course (DOTS) strategy in the former Gdansk Province led to improved outcomes compared to the outcomes observed in 1995, when this strategy was not being followed. MATERIAL AND METHODS: We started the study by reviewing microbiology registers covering the years 1995 and 2000 from all the tuberculosis laboratories in three provinces (Warsaw, Gdansk and Siedlce Provinces) and identified sputum culture positive patients. We then reviewed inpatient and outpatient medical records of patients who had been with pulmonary tuberculosis diagnosed and confirmed by bacteriology in 1995 and 2000. Treatment outcomes were evaluated in accordance with the World Health Organisation (WHO) recommendations and classified as: cure, treatment completed, default, treatment failure, death or other. RESULTS: A total of 708 patients were included in the study: 373 diagnosed in 1995 and 335 diagnosed in 2000. According to the WHO criteria, the treatment success rate (the sum of cures and treatment completions) in 1995 and 2000 was 58.8% and 54.0%, the default rate was 15.5% and 17.9%, the failure rate was 2.4% and 2.7% and the death rate was 5.6% and 6.3%, respectively. The rate of outcomes classified as "other" was 18.2% and 22.1%, respectively. Following the implementation of the DOTS strategy in Gdansk Province, treatment outcomes in significantly improved in 2000 compared to the year 1995. The treatment success rate was 89.6% vs 69.3% (p = 0.0037), the default rate was 0.0% vs. 14.7% (p = 0.0005) and the death rate was 0.0% vs. 9.3% (p = 0.0184). CONCLUSIONS: The treatment success rate (the rate of cures and treatment completers) in 1995 and 2000 was 58.8% and 54.0% and was lower than that recommended by WHO (at least 85%). The results demonstrated that the treatment outcomes in the former Gdansk Province in 2000, following the implementation of the DOTS strategy, were significantly better than those in 1995, when the strategy was not being followed. Treatment success was observed in 89.6% and 69.3% of the patients, respectively (p = 0.0037).

Preventing low birthweight through maternal multiple micronutrient supplementation: a cluster-randomized, controlled trial in Indramayu, West Java.

BACKGROUND: Micronutrient deficiencies may contribute to a higher incidence of low birthweight (LBW). UNICEF/United Nations University/World Health Organization jointly proposed a formulation for a multiple micronutrient supplement for pregnant women, and several effectiveness trials were conducted to assess its impact. OBJECTIVE: To evaluate the efficacy of prenatal multiple micronutrient supplementation for improving birth size, pregnancy outcome, and maternal micronutrient status in comparison with iron-folic acid supplementation. METHODS: We carried out a cluster-randomized, controlled trial in Indramayu, Indonesia, involving 843 pregnant women. Of these, 432 received multiple micronutrients and 411 received iron-folic acid. Fieldworkers visited the women daily to observe supplement consumption and record fetal loss and mortality. RESULTS: The mean number of supplements consumed during pregnancy and 30 days postpartum was high (136 in the group receiving multiple micronutrients and 140 in the iron-folic acid group). The women consumed the supplements on average 5 days per week. Although there were no significant differences between the groups in the percentage of infants with LBW there was a trend toward a lower incidence of LBW in the group receiving multiple micronutrients (6.3% vs. 7.3%), and the mean birthweight was 40 g higher in the group receiving multiple micronutrients than in the iron-folic acid group, although the difference was not significant. Among those who consumed 90 or more supplements during pregnancy, women taking multiple micronutrients had a 3.3% combined rate of miscarriage, stillbirth, or neonatal death, as compared with 6.9% for those taking iron-folic acid only (p < .049). The anemia rates in the two groups were similar after supplementation, even though the amount of iron in the multiple micronutrient supplement was half that in the iron-folic acid supplement. Serum retinol was higher in the group receiving multiple micronutrients. CONCLUSIONS: Multivitamin supplementation use among pregnant women is as effective as iron-folic acid in improving anemia status and appears to have other benefits for maternal and child nutritional status.

Increasing tuberculosis case detection: lessons from the Republic of Moldova.

The Republic of Moldova undertook reforms in tuberculosis (TB) control and health care consistent with international recommendations and advanced towards the global target for case detection. The number of TB cases notified increased overall by 50% during 2001-2005. Expansion of the DOTS strategy and full coverage coincided with a greater role for primary health care (PHC) in TB control and the advent of national insurance for TB diagnosis and treatment. These developments and improvements in laboratories, surveillance, medical personnel skills, and public awareness contributed to increased case detection. The Republic of Moldova addressed both demand and supply sides in these efforts. It increased effective demand for TB services by dispersing diagnostic capability, instituting financing mechanisms and saturating the public with information on symptoms, transmission and treatment. It increased the supply of TB services by upgrading the laboratory network, revamping surveillance and training practitioners. The Republic of Moldova's experience offers lessons for other countries: TB-PHC integration allowed more suspect cases to be diagnosed at nearby PHC clinics, contributing to more cases being notified. Innovative TB communications reached the general public, vulnerable groups, practitioners and the media. TB control projects built on each other and national coordination mechanisms served to identify funding for the most pressing needs. There are challenges remaining for TB control in the Republic of Moldova, not least the stable treatment success rate, but the country can list valuable lessons and achievements.

The road to tuberculosis treatment in rural Nepal: A qualitative assessment of 26 journeys.

BACKGROUND: The fact that tuberculosis can be treated with the DOTS strategy (Directly Observed Treatment, Short-course) is not enough to control the disease. Patients have to find their way to tuberculosis treatment first. To better understand the route to tuberculosis treatment in rural Nepal we interviewed twenty-six patients under treatment. METHODS: In semi-structured interviews patients shared their disease history and health seeking behaviour. The analysis focused on the encounters with the health care system before enrolment in the tuberculosis treatment program. RESULTS: Patient routes often started in the medical shop and led via intricate routes with multiple providers to facilities with higher qualified and more competent staff where tuberculosis was diagnosed. Several factors influenced the route to tuberculosis treatment. Besides known patients factors (such as severity of complaints, the ability to pay for services, availability of services and peer support for choosing a provider) specific health services factors were also identified. These included the perceived quality, costs and service level of a provider, and lack of provider initiated referral. Self referral because of waned trust in the provider was very common. In contrast, once tuberculosis was considered a possible diagnosis, referral to diagnostic testing and tuberculosis treatment was prompt. CONCLUSION: Patient routes towards tuberculosis treatment are characterised by self referral and include both private and public health care providers. Once tuberculosis is suspected referral for diagnosis and treatment is prompt. Given the importance of the private practitioners in the patient routes, quality improvement initiatives need to address not only the public sector but the private health care sector as well.

Descriptive study of the implementation and impact of the directly observed treatment, short-course strategy in the São José do Rio Preto municipal tuberculosis control program (1998-2003).

OBJECTIVE: To describe treatment outcomes (cure, noncompliance or death) after the implementation of the Directly Observed Treatment, Short-course (DOTS) strategy for tuberculosis control in the city of São José do Rio Preto, Brazil, between 1998 and 2003. METHODS: A descriptive study, based on secondary data (National Case Registry database, Tuberculosis Epidemiology database, and the 'Black Book' Registry), was conducted using a specific instrument. The data were analyzed using descriptive statistics. RESULTS: After the implementation of the DOTS strategy, there was a decrease in noncompliance and case detection rates as well as an increase in cure and death rates. The increase in the number of tuberculosis-related deaths might be attributable to three factors: the predominance of the disease in individuals over 50 years of age, tuberculosis/HIV co-infection, and the presence of accompanying diseases. CONCLUSION: The implementation of the DOTS strategy strengthened the decentralization of the tuberculosis control plans as well as the integration of the Basic Health Care Clinic teams with the Tuberculosis Control Program team. Political commitment of the administrator to tuberculosis control, in conjunction with the policy of benefits and incentives, is essential for the sustainability of the DOTS strategy.

Estudo descritivo sobre a implantação da estratégia de tratamento de curta duração diretamente observado no controle da tuberculose em São José do Rio Preto e seus impactos (1998-2003) / Descriptive study of the implementation and impact of the directly observed treatment, short-course strategy in the São José do Rio Preto municipal tuberculosis control program (1998-2003)

OBJETIVO: Descrever os resultados de tratamento (cura, abandono ou óbito) após a implantação da estratégia de tratamento de curta duração diretamente observado (Directly Observed Treatment, Short-course - DOTS) no controle da tuberculose em São José do Rio Preto, São Paulo, no período de 1998 a 2003. MÉTODOS: Estudo descritivo que utilizou fontes secundárias de informações (Sistema Nacional de Agravos de Notificação, Sistema de Notificação de Tuberculose, Livro de Registro/Livro Preto) por meio de um instrumento específico. Os dados foram analisados por estatística descritiva. RESULTADOS: Após a implantação da estratégia DOTS houve uma diminuição das taxas de abandono e detecção de casos e um aumento das taxas de cura e óbito. O aumento do número de óbitos por tuberculose pode ter ocorrido devido a três fatores: o predomínio da doença em indivíduos acima de 50 anos; a co-infecção tuberculose/HIV e a presença de doenças associadas. CONCLUSÕES: A implantação da estratégia DOTS fortaleceu a descentralização das ações de controle da tuberculose e a integração das equipes das Unidades Básicas de Saúde com a equipe do Programa de Controle da Tuberculose. O compromisso político do gestor com o combate à tuberculose, aliado à política de benefícios e incentivos, é fundamental para a sustentabilidade da estratégia DOTS.

What is the limit to case detection under the DOTS strategy for tuberculosis control?

In year 2000, the WHO DOTS strategy for tuberculosis (TB) control had been adopted by 148 out of 212 countries, but only 27% of all estimated sputum smear-positive patients were notified under DOTS in that year. Here we investigate the way in which gains in case detection under DOTS were made up until 2000 in an attempt to anticipate future progress towards the global target of 70% case detection. The analysis draws on annual reports of DOTS geographical coverage and case notifications, and focuses on the 22 high-burden countries (HBCs) that account for about 80% of new TB cases arising globally each year. Our principal observation is that, as TB programmes in the 22 HBCs have expanded geographically, the fraction of the estimated number of sputum smear-positive cases detected within designated DOTS areas has remained constant at 40-50% although there are significant differences between countries. This fraction is about the same as the percentage of all smear-positive cases notified annually to WHO via public health systems worldwide. The implication is that, unless the DOTS strategy can reach beyond traditional public health reporting systems, or unless these systems can be improved, case detection will not rise much above 40% in the 22 HBCs, or in the world as a whole, even when the geographical coverage of DOTS is nominally 100%. We estimate that, under full DOTS coverage, three-quarters of the undetected smear-positive cases will be living in India, China, Indonesia, Nigeria, Bangladesh and Pakistan. But case detection could also remain low in countries with smaller populations: in year 2000, over half of all smear-positive TB cases were living in 49 countries that detected less than 40% of cases within DOTS areas. Substantial efforts are therefore needed (a) to develop new case finding and management methods to bridge the gap between current and target case detection, and (b) to improve the accuracy of national estimates of TB incidence, above all by reinforcing and expanding routine surveillance.
