A process for developing a sustainable and scalable approach to community engagement: community dialogue approach for addressing the drivers of antibiotic resistance in Bangladesh.

BACKGROUND: Community engagement approaches that have impacted on health outcomes are often time intensive, small-scale and require high levels of financial and human resources. They can be difficult to sustain and scale-up in low resource settings. Given the reach of health services into communities in low income countries, the health system provides a valuable and potentially sustainable entry point that would allow for scale-up of community engagement interventions. This study explores the process of developing an embedded approach to community engagement taking the global challenge of antibiotic resistance as an example. METHODS: The intervention was developed using a sequential mixed methods study design. This consisted of: exploring the evidence base through an umbrella review, and identifying key international standards on the appropriate use of antibiotics; undertaking detailed formative research through a) a qualitative study to explore the most appropriate mechanisms through which to embed the intervention within the existing health system and community infrastructure, and to understand patterns of knowledge, attitudes and practice regarding antibiotics and antibiotic resistance; and b) a household survey - which drew on the qualitative findings - to quantify knowledge, and reported attitudes and practice regarding antibiotics and antibiotic resistance within the target population; and c) drawing on appropriate theories regarding change mechanisms and experience of implementing community engagement interventions to co-produce the intervention processes and materials with key stakeholders at policy, health system and community level. RESULTS: A community engagement intervention was co-produced and was explicitly designed to link into existing health system and community structures and be appropriate for the cultural context, and therefore have the potential to be implemented at scale. We anticipate that taking this approach increases local ownership, as well as the likelihood that the intervention will be sustainable and scalable. CONCLUSIONS: This study demonstrates the value of ensuring that a range of stakeholders co-produce the intervention, and ensuring that the intervention is designed to be appropriate for the health system, community and cultural context.

Long-term outcomes of an educational intervention to reduce antibiotic prescribing for childhood upper respiratory tract infections in rural China: Follow-up of a cluster-randomised controlled trial.

BACKGROUND: Inappropriate antibiotic prescribing causes widespread serious health problems. To reduce prescribing of antibiotics in Chinese primary care to children with upper respiratory tract infections (URTIs), we developed an intervention comprising clinical guidelines, monthly prescribing review meetings, doctor-patient communication skills training, and education materials for caregivers. We previously evaluated our intervention using an unblinded cluster-randomised controlled trial (cRCT) in 25 primary care facilities across two rural counties. When our trial ended at the 6-month follow-up period, we found that the intervention had reduced antibiotic prescribing for childhood URTIs by 29 percentage points (pp) (95% CI -42 to -16). METHODS AND FINDINGS: In this long-term follow-up study, we collected our trial outcomes from the one county (14 facilities and 1:1 cluster randomisation ratio) that had electronic records available 12 months after the trial ended, at the 18-month follow-up period. Our primary outcome was the antibiotic prescription rate (APR)-the percentage of outpatient prescriptions containing any antibiotic(s) for children aged 2 to 14 years who had a primary diagnosis of a URTI and had no other illness requiring antibiotics. We also conducted 15 in-depth interviews to understand how interventions were sustained. In intervention facilities, the APR was 84% (1,171 out of 1,400) at baseline, 37% (515 out of 1,380) at 6 months, and 54% (2,748 out of 5,084) at 18 months, and in control facilities, it was 76% (1,063 out of 1,400), 77% (1,084 out of 1,400), and 75% (2,772 out of 3,685), respectively. After adjusting for patient and prescribing doctor covariates, compared to the baseline intervention-control difference, the difference at 6 months represented a 6-month intervention-arm reduction in the APR of -49 pp (95% CI -63 to -35; P < 0.0001), and compared to the baseline difference, the difference at 18 months represented an 18-month intervention-arm reduction in the APR of -36 pp (95% CI -55 to -17; P < 0.0001). Compared to the 6-month intervention-control difference, the difference at 18 months represented no change in the APR: 13 pp (95% CI -7 to 33; P = 0.21). Factors reported to sustain reductions in antibiotic prescribing included doctors' improved knowledge and communication skills and focused prescription review meetings, whereas lack of supervision and monitoring may be associated with relapse. Key limitations were not including all clusters from the trial and not collecting returned visits or sepsis cases. CONCLUSIONS: Our intervention was associated with sustained and substantial reductions in antibiotic prescribing at the end of the intervention period and 12 months later. Our intervention may be adapted to similar resource-poor settings. TRIAL REGISTRATION: ISRCTN registry ISRCTN14340536.

Analysis of loss to follow-up in 4099 multidrug-resistant pulmonary tuberculosis patients.

Loss to follow-up (LFU) of ≥2 consecutive months contributes to the poor levels of treatment success in multidrug-resistant tuberculosis (MDR-TB) reported by TB programmes. We explored the timing of when LFU occurs by month of MDR-TB treatment and identified patient-level risk factors associated with LFU.We analysed a dataset of individual MDR-TB patient data (4099 patients from 22 countries). We used Kaplan-Meier survival curves to plot time to LFU and a Cox proportional hazards model to explore the association of potential risk factors with LFU.Around one-sixth (n=702) of patients were recorded as LFU. Median (interquartile range) time to LFU was 7 (3-11) months. The majority of LFU occurred in the initial phase of treatment (75% in the first 11 months). Major risk factors associated with LFU were: age 36-50 years (HR 1.3, 95% CI 1.0-1.6; p=0.04) compared with age 0-25 years, being HIV positive (HR 1.8, 95% CI 1.2-2.7; p<0.01) compared with HIV negative, on an individualised treatment regimen (HR 0.7, 95% CI 0.6-1.0; p=0.03) compared with a standardised regimen and a recorded serious adverse event (HR 0.5, 95% CI 0.4-0.6; p<0.01) compared with no serious adverse event.Both patient- and regimen-related factors were associated with LFU, which may guide interventions to improve treatment adherence, particularly in the first 11 months.

Nutrition transition, overweight and obesity among rural-to-urban migrant women in Kenya.

OBJECTIVE: To assess the effect of rural-to-urban migration on nutrition transition and overweight/obesity risk among women in Kenya. DESIGN: Secondary analysis of data from nationally representative cross-sectional samples. Outcome variables were women's BMI and nutrition transition. Nutrition transition was based on fifteen different household food groups and was adjusted for socio-economic and demographic characteristics. Stepwise backward multiple ordinal regression analysis was applied. SETTING: Kenya Demographic and Health Survey 2014. PARTICIPANTS: Rural non-migrant, rural-to-urban migrant and urban non-migrant women aged 15-49 years (n 6171). RESULTS: Crude data analysis showed rural-to-urban migration to be associated with overweight/obesity risk and nutrition transition. After adjustment for household wealth, no significant differences between rural non-migrants and rural-to-urban migrants for overweight/obesity risk and household consumption of several food groups characteristic of nutrition transition (animal-source, fats and sweets) were observed. Regardless of wealth, migrants were less likely to consume main staples and legumes, and more likely to consume fruits and vegetables. Identified predictive factors of overweight/obesity among migrant women were age, duration of residence in urban area, marital status and household wealth. CONCLUSIONS: Our analysis showed that nutrition transition and overweight/obesity risk among rural-to-urban migrants is apparent with increasing wealth in urban areas. Several predictive factors were identified characterising migrant women being at risk for overweight/obesity. Future research is needed which investigates in depth the association between rural-to-urban migration and wealth to address inequalities in diet and overweight/obesity in Kenya.

Using behaviour change theory to train health workers on tobacco cessation support for tuberculosis patients: a mixed-methods study in Bangladesh, Nepal and Pakistan.

BACKGROUND: Low- and middle-income countries (LMICs) are disproportionately impacted by interacting epidemics of tuberculosis (TB) and tobacco consumption. Research indicates behavioural support delivered by health workers effectively promotes tobacco cessation. There is, however, a paucity of training to support LMIC health workers deliver effective tobacco cessation behavioural support. The TB and Tobacco Consortium undertook research in South Asia to understand factors affecting TB health workers' delivery of tobacco cessation behavioural support, and subsequently developed a training package for LMICs. METHODS: Using the "capability, opportunity, and motivation as determinants of behaviour" (COM-B) framework to understand any issues facing health worker delivery of behaviour support, we analysed 25 semi-structured interviews and one focus group discussion with TB health workers, facility in-charges, and national tuberculosis control programme (NTP) staff members in each country. Results were integrated with findings of an adapted COM-B questionnaire on health worker confidence in tobacco cessation support delivery, administered to 36 TB health workers. Based on findings, we designed a guide and training programme on tobacco cessation support for health workers. RESULTS: Qualitative results highlighted gaps in the majority of health workers' knowledge on tobacco cessation and TB and tobacco interaction, inadequate training on patient communication, insufficient resources and staff support, and NTPs' non-prioritization of tobacco cessation in all three countries. Questionnaire results reiterated the knowledge deficits and low confidence in patient communication. Participants suggested strengthening knowledge, skills, and competence through training and professional incentives. Based on findings, we developed an interactive two-day training and TB health worker guide adaptable for LMICs, focusing on evidence of best practice on TB and tobacco cessation support, communication, and rapport building with patients. CONCLUSIONS: TB health workers are essential in addressing the dual burden of TB and tobacco faced by many LMICs. Factors affecting their delivery of tobacco cessation support can be identified using the COM-B framework, and include issues such as individuals' knowledge and skills, as well as structural barriers like professional support through monitoring and supervision. While structural changes are needed to tackle the latter, we have developed an adaptable and engaging health worker training package to address the former that can be delivered in routine TB care.

"Who Will Marry a Diseased Girl?" Marriage, Gender, and Tuberculosis Stigma in Asia.

In a qualitative study on the stigma associated with tuberculosis (TB), involving 73 interviews and eight focus groups conducted in five sites across three countries (Bangladesh, Nepal, and Pakistan), participants spoke of TB's negative impact on the marriage prospects of women in particular. Combining the approach to discovering grounded theory with a conceptualization of causality based on a realist ontology, we developed a theory to explain the relationships between TB, gender, and marriage. The mechanism at the heart of the theory is TB's disruptiveness to the gendered roles of wife (or daughter-in-law) and mother. It is this disruptiveness that gives legitimacy to the rejection of marriage to a woman with TB. Whether or not this mechanism results in a negative impact of TB on marriage prospects depends on a range of contextual factors, providing opportunities for interventions and policies.

Embedded health service development and research: why and how to do it (a ten-stage guide).

In a world of changing disease burdens, poor quality care and constrained health budgets, finding effective approaches to developing and implementing evidence-based health services is crucial. Much has been published on developing service tools and protocols, operational research and getting policy into practice but these are often undertaken in isolation from one another. This paper, based on 25 years of experience in a range of low and middle income contexts as well as wider literature, presents a systematic approach to connecting these activities in an embedded development and research approach. This approach can circumvent common problems such as lack of local ownership of new programmes, unrealistic resource requirements and poor implementation.We lay out a ten-step process, which is based on long-term partnerships and working within local systems and constraints and may be tailored to the context and needs. Service development and operational research is best prioritised, designed, conducted and replicated when it is embedded within ministry of health and national programmes. Care packages should from the outset be designed for scale-up, which is why the piloting stage is so crucial. In this way, the resulting package of care will be feasible within the context and will address local priorities. Researchers must be entrepreneurial and responsive to windows of funding for scale-up, working in real-world contexts where funding and decisions do not wait for evidence, so evidence generation has to be pragmatic to meet and ensure best use of the policy and financing cycles. The research should generate tested and easily usable tools, training materials and processes for use in scale-up. Development of the package should work within and strengthen the health system and other service delivery strategies to ensure that unintended negative consequences are minimised and that the strengthened systems support quality care and effective scale up of the package.While embedded development and research is promoted in theory, it is not yet practiced at scale by many initiatives, leading to wasted resources and un-sustained programmes. This guide presents a systematic and practical guide to support more effective engagements in future, both in developing interventions and supporting evidence-based scale-up.

Effect of cessation interventions on hookah smoking: post-hoc analysis of a cluster-randomized controlled trial.

INTRODUCTION: We explored the differential effect of cessation interventions (behavioral support sessions with [BSS+] and without [BSS] bupropion) between hookah and cigarette smokers. METHODS: We reanalyzed the data from a major cluster-randomized controlled trial, ASSIST (Action to Stop Smoking In Suspected Tuberculosis), which consisted of 3 conditions: (a) behavioral support sessions (BSS), (b) behavioral support sessions plus 7 weeks of bupropion therapy (BSS+), and (c) controls receiving usual care. The trial originally recruited 1,955 adult smokers with suspected tuberculosis from 33 health centers in the Jhang and Sargodha districts of Pakistan between 2010 and 2011. The primary endpoint was continuous 6-month smoking abstinence, which was determined by carbon monoxide levels. Subgroup-specific relative risks (RRs) of smoking abstinence were computed and tested for differential intervention effect using log binomial regression (generalized linear model) between 3 subgroups (cigarette-only: 1,255; mixed: 485; and hookah-only: 215). RESULTS: The test result for homogeneity of intervention effects between the smoking forms was statistically significant (p-value for BSS+: .04 and for BSS: .02). Compared to the control, both interventions appeared to be effective among hookah smokers (RR = 2.5; 95% CI = 1.3-4.7 and RR = 2.2; 95% CI = 1.3-3.8, respectively) but less effective among cigarette smokers (RR = 6.6; 95% CI = 4.6-9.6 and RR = 5.8; 95% CI = 4.0-8.5), respectively. CONCLUSIONS: The differential intervention effects on hookah and cigarette smokers were seen (a) because the behavioral support intervention was designed primarily for cigarette smokers; (b) because of differences in demographic characteristics, behavioral, and sociocultural determinants; or (c) because of differences in nicotine dependency levels between the 2 groups.

Patients' perspectives of care for type 2 diabetes in Bangladesh -a qualitative study.

BACKGROUND: Worldwide, type 2 diabetes affects approximately 220 million people and is the cause of 1.1 million deaths each year, 80% of which occur in low and middle income countries (LMICs). Over the next 20 years, prevalence is expected to double worldwide and increase by 150% in LMICs. There is now a move towards improving care for diabetes. However no information on patients' needs, perceptions and experiences is available, hindering effective and appropriate changes in policy and practice. We developed a study with the objective of understanding patients' experiences of treatment for type 2 diabetes. METHODS: During January 2011, we conducted in-depth interviews in five sites across two administrative districts of Bangladesh, purposefully chosen to represent different geographic regions and local demographics In total, we conducted 23 (14 male, 9 female) individual interviews across the 5 sites, to gain insight into patients' understanding of their diabetes and its management. RESULTS: Patients' levels of knowledge and understanding about diabetes and its management is depended on where they received their initial diagnosis and care. Away from specialist centres, patients had poor understanding of the essential of diabetes and its management. No appropriate written or verbal information was available for a significant number of patients, compounded limited knowledge and understanding of diabetes by healthcare professionals. Patients felt that with improved provision of appropriate information they would be able to better understand their diabetes and improve their role in its management. Access to appropriate diagnosis and subsequent treatment was restricted by availability and costs of services. CONCLUSION: Effective, appropriate and essential healthcare services for diabetes in Bangladesh is extremely limited, a majority of patients receive suboptimal care. Site of diagnosis will impact significantly on the quality of information provided and the quality of subsequent treatments. Although appropriate services are available at some specialist centres, the inability of patients to pay for routine tests and check-ups prevents them from receiving timely diagnoses and appropriate continuity of care. The double burden of communicable diseases and diseases is now a well-recognised. Emphasis must be placed on developing appropriate and effective preventive strategies to address this burden.

The importance of providing counselling and financial support to patients receiving treatment for multi-drug resistant TB: mixed method qualitative and pilot intervention studies.

BACKGROUND: People with multi-drug resistant tuberculosis (MDR-TB) in low-income countries face many problems during treatment, and cure rates are low. The purpose of the study was (a) to identify and document the problems experienced by people receiving care for MDR-TB, and how they cope when support is not provided, to inform development of strategies; (b) to estimate the effectiveness of two resultant strategies, counselling alone, and joint counselling and financial support, of increasing DOTS-plus treatment success under routine programme conditions. METHODS: A mixed-method study comprising a formative qualitative study, pilot intervention study and explanatory qualitative study to better understand barriers to completion of treatment for MDR-TB. Participants were all people starting MDR-TB treatment in seven DOTS-plus centres in the Kathmandu Valley, Nepal during January to December 2008. The primary outcome measure was cure, as internationally defined. RESULTS: MDR-TB treatment caused extreme social, financial and employment hardship. Most patients had to move house and leave their job, and reported major stigmatisation. They were concerned about the long-term effects of their disease, and feared infecting others. In the resultant pilot intervention study, the two strategies appeared to improve treatment outcomes: cure rates for those receiving counselling, combined support and no support were 85%, 76% and 67% respectively. Compared with no support, the (adjusted) risk ratios of cure for those receiving counselling and receiving combined support were 1.2 (95% CI 1.0 to 1.6) and 1.2 (95% CI 0.9 to 1.6) respectively. The explanatory study demonstrated that patients valued both forms of support. CONCLUSIONS: MDR-TB patients are extremely vulnerable to stigma and extreme financial hardship. Provision of counselling and financial support may not only reduce their vulnerability, but also increase cure rates. National Tuberculosis Programmes should consider incorporating financial support and counselling into MDR-TB care: costs are low, and benefits high, especially since costs to society of incomplete treatment and potential for incurable TB are extremely high.

Action to stop smoking in suspected tuberculosis (ASSIST) in Pakistan: a cluster randomized, controlled trial.

BACKGROUND: Tobacco use is responsible for a large proportion of the total disease burden from tuberculosis. Pakistan is one of the 10 high-burden countries for both tuberculosis and tobacco use. OBJECTIVE: To assess the effectiveness of a behavioral support intervention and bupropion in achieving 6-month continuous abstinence in adult smokers with suspected pulmonary tuberculosis. DESIGN: Cluster randomized, controlled trial. (Current Controlled Trials: ISRCTN08829879) SETTING: Health centers in the Jhang and Sargodha districts in Pakistan. PATIENTS: 1955 adult smokers with suspected tuberculosis. INTERVENTION: Health centers were randomly assigned to provide 2 brief behavioral support sessions (BSS), BSS plus 7 weeks of bupropion therapy (BSS+), or usual care. MEASUREMENTS: The primary end point was continuous abstinence at 6 months after the quit date and was determined by carbon monoxide levels in patients. Secondary end points were point abstinence at 1 and 6 months. RESULTS: Both treatments led to statistically significant relative risks (RRs) for abstinence compared with usual care (RR for BSS+, 8.2 [95% CI, 3.7 to 18.2]; RR for BSS, 7.4 [CI, 3.4 to 16.4]). Equivalence between the treatments could not be established. In the BSS+ group, 275 of 606 patients (45.4% [CI, 41.4% to 49.4%]) achieved continuous abstinence compared with 254 of 620 (41.0% [CI, 37.1% to 45.0%]) in the BSS group and 52 of 615 (8.5% [CI, 6.4% to 10.9%]) in the usual care group. There was substantial heterogeneity of program effects across clusters. LIMITATIONS: Imbalances in the urban and rural proportions and smoking habits among treatment groups, and inability to confirm adherence to bupropion treatment and validate longer-term abstinence or the effect of smoking cessation on tuberculosis outcomes. CONCLUSION: Behavioral support alone or in combination with bupropion is effective in promoting cessation in smokers with suspected tuberculosis.

Itaconic Acid as a Comonomer in Betulin-Based Thermosets via Sequential and Bulk Preparation.

The inherent chemical functionalities of biobased monomers enable the production of renewably sourced polymers that further advance sustainable manufacturing. Itaconic acid (IA) is a nontoxic, commercially produced biobased monomer that can undergo both UV and thermal curing. Betulin is a biocompatible, structurally complex diol derived from birch tree bark that has been recently studied for materials with diverse applications. Here, betulin, IA, and biobased linear diacids, 1,12-dodecanedioic acid (C12) and 1,18-octadecanedioic acid (C18), were used to prepare thermosets using sequential and bulk curing methods. Thermoplastic polyester precursors were synthesized and formulated into polyester-methacrylate (PM) resins to produce sequential UV-curable thermosets. Bulk-cured polyester thermosets were prepared using a one-pot, solventless melt polycondensation using glycerol as a cross-linker. The structure-property relationships of the thermoplastic polyester precursors, sequentially prepared PM thermosets, and bulk-cured polyester thermosets were evaluated with varying IA content. Both types of thermosets exhibited higher storage moduli, Tgs, and thermal stabilities with greater IA comonomer content. These results demonstrate the viability of using IA as a comonomer to produce betulin-based thermosets each with tunable properties, expanding the scope of their applications and use in polymeric materials.

Implementation of the Chinese national microscopy centre policy: health facility survey in Shandong Province.

OBJECTIVE: In compliance with Chinese national policy, Shandong province set up microscopy centres (MCs) in one-third of all township hospitals where sputum smear microscopy is performed. We assessed the centres' performance and any factors influencing it. METHODS: A cross-sectional, structured, facility-based questionnaire survey was conducted in 2006, collecting data from all 113 counties with established MCs as well as tuberculosis (TB) routine reporting data from the county TB dispensary. RESULTS: One hundred and thirteen of 142 counties in Shandong had established 497 MCs. The centres identified 3.3% of smear-positive patients in the province. Sixty-six percentage of MCs did not identify any patients with TB; only 5% identified more than 10. Poor performance arose from low quality of staff training in township hospitals, but inappropriate geographical provision of services was the main cause of low additional case finding. CONCLUSION: The MC policy did not achieve its goal of improving TB case finding in Shandong.

Evaluating the impact of decentralising tuberculosis microscopy services to rural township hospitals in Gansu Province, China.

BACKGROUND: In 2004, the Ministry of Health issued the policy of decentralising microscopy services (MCs) to one third of all township hospitals in China. The study was conducted in Gansu Province, a poor western one in China. Ganzhou was one county in Gansu Province. Ganzhou County was identified as a unique case of further decentralisation of tuberculosis (TB) treatment services in township hospitals. The study evaluated the impact of the MC policy on providers and patients in Gansu Province. The second objective was to assess the unique case of Ganzhou County compared with other counties in the province. METHODS: Both quantitative and qualitative methods were used. All 523 MCs in the province completed an institutional survey regarding their performance. Four counties were selected for in-depth investigation, where 169 TB suspects were randomly selected from the MC and county TB dispensary registers for questionnaire surveys. Informant interviews were conducted with 38 health staff at the township and county levels in the four counties. RESULTS: Gansu established MCs in 39% of its township hospitals. From January 2006 to June 2007, 8% of MCs identified more than 10 TB sputum smear positive patients while 54% did not find any. MCs identified 1546 TB sputum smear positive patients, accounting for 9% of the total in the province. The throughputs of MCs in Ganzhou County were eight times of those in other counties. Interviews identified several barriers to implement the MC policy, such as inadequate health financing, low laboratory capacity, lack of human resources, poor treatment and management capacities, and lack of supervisions from county TB dispensaries. CONCLUSION: Microscopy centre throughputs were generally low in Gansu Province, and the contribution of MCs to TB case detection was insignificant taking account the number of MCs established. As a unique case of full decentralisation of TB service, Ganzhou County presented better results. However, standards and quality of TB care needed to be improved. The MC policy needs to be reviewed in light of evidence from this study.

Tanzanian farmers' knowledge and attitudes to GM biotechnology and the potential use of GM crops to provide improved levels of food security. A Qualitative Study.

BACKGROUND: Genetically Modified (GM) crops have been championed as one possible method to improve food security and individual nutritional status in sub Saharan Africa. Understanding and acceptability of GM crop technology to farmers and consumers have not been assessed. We developed a qualitative research study involving farmers as both producers and consumers to gauge the understanding of GM crop technology, its acceptability, and identifying issues of concern. METHODS: Nineteen individual interviews (10 male and 9 female) and five mixed gender focus group discussions with local farmers were conducted in 3 regions in Tanzania. Analysis took place concurrently with data collection. Following initial interviews, subsequent questions were adjusted based on emerging themes. RESULTS: Understanding, awareness and knowledge of GM crop technology and terminology and its potential risks and benefits was very poor in all regions. Receptivity to the potential use of GM crops was, however, high. Respondents focused on the potential benefits of GM crops rather than any potential longer term health risks. A number of factors, most significantly field trial data, would influence farmers' decisions regarding the introduction of GM crop varieties into their farming practice. Understanding of the potential improved health provision possible by changes in agricultural practice and food-related decision making, and the health benefits of a diet containing essential vitamins, minerals and micronutrients is also poor in these communities. CONCLUSION: This study forms a basis from which further research work can be undertaken. It is important to continue to assess opinions and attitudes of farmers and consumers in sub Saharan Africa towards potential use of GM technologies whilst highlighting the importance of the relationship between agriculture, health and development. This will allow people in the region to make accurate, informed decisions about whether they believe use of GM biotechnology is an appropriate way in which to tackle issues of food security, provide improved health and drive development.

Cost implications of delays to tuberculosis diagnosis among pulmonary tuberculosis patients in Ethiopia.

BACKGROUND: Delays seeking care worsen the burden of tuberculosis and cost of care for patients, families and the public health system. This study investigates costs of tuberculosis diagnosis incurred by patients, escorts and the public health system in 10 districts of Ethiopia. METHODS: New pulmonary tuberculosis patients > or = 15 years old were interviewed regarding their health care seeking behaviour at the time of diagnosis. Using a structured questionnaire patients were interviewed about the duration of delay at alternative care providers and the public health system prior to diagnosis. Costs incurred by patients, escorts and the public health system were quantified through patient interview and review of medical records. RESULTS: Interviews were held with 537 (58%) smear positive patients and 387 (42%) smear negative pulmonary patients. Of these, 413 (45%) were female; 451 (49%) were rural residents; and the median age was 34 years. The mean (median) days elapsed for consultation at alternative care providers and public health facilities prior to tuberculosis diagnosis was 5 days (0 days) and 3 (3 days) respectively. The total median cost incurred from first consultation to diagnosis was $27 per patient (mean = $59). The median costs per patient incurred by patient, escort and the public health system were $16 (mean = $29), $3 (mean = $23) and $3 (mean = $7) respectively. The total cost per patient diagnosed was higher for women, rural residents; those who received government food for work support, patients with smear negative pulmonary tuberculosis and patients who were not screened for TB in at least one district diagnostic centers. CONCLUSIONS: The costs of tuberculosis diagnosis incurred by patients and escorts represent a significant portion of their monthly income. The costs arising from time lost in seeking care comprised a major portion of the total cost of diagnosis, and may worsen the economic position of patients and their families. Getting treatment from alternative sources and low index of suspicion public health providers were key problems contributing to increased cost of tuberculosis diagnosis. Thus, the institution of effective systems of referral, ensuring screening of suspects across the district public health system and the involvement of alternative care providers in district tuberculosis control can reduce delays and the financial burden to patients and escorts.

Health SWAps and external aid--a case study from Tajikistan.

As it moves from a relief to a development phase, the Republic of Tajikistan (RT) needs to attract more external aid and to ensure adequate alignment of this aid with health systems development priorities. A potential response to these two needs is a Sector-Wide Approach (SWAp), a method originating from post-colonial Africa and Asia that is increasingly being introduced in new contexts. However, little is known about whether SWAps are appropriate in the context of the former Soviet Union (FSU). This paper explores SWAps using Tajikistan as a case study. A number of lessons are identified for the Tajik health system, for other FSU countries and for health SWAps in general, covering issues of practical relevance to national and international health policy-makers.We conclude that context-specific SWAps may be developed to suit Tajikistan, and other FSU countries. Tajikistan currently does not yet have all the key SWAp elements in place, but this should be seen as a motive for, rather than an impediment to, developing a SWAp. Other FSU countries have a more favourable environment for implementing health SWAps.

The social reality of migrant men with tuberculosis in Kathmandu: implications for DOT in practice.

OBJECTIVE: To establish which of the many possible linkages between tuberculosis (TB), direct observation of treatment (DOTS), and the social reality of migrant workers in Kathmandu are the most relevant to the health outcomes and economic and social well-being of these populations, and which are amenable to possible interventions and high-yield policy changes. METHODS: Fourteen semi-structured in-depth interviews were conducted through an interpreter with male migrant TB patients aged 18-50 years recruited from three DOTS clinics in the Kathmandu valley in May 2005. The interviews were coded using constant comparison and analysed using a grounded theory method. RESULTS: The economic burden of TB treatment is far greater than the financial reserve of migrants. Consequently remittances sent to families are reduced and migrants remain in debt long after treatment completion, tied to the treatment location paying off high interest loans. Forced to attend clinics far away from their home, and isolated by the stigma associated with TB, migrants are vulnerable without social support networks. Migrants find that daily clinic visits are incompatible with working schedules and important cultural festivals, which forces them into defaulting. CONCLUSION: The needs of migrant workers with TB living in Kathmandu are not being adequately met. Current service provision needs to be reviewed to build in greater flexibility and support for migrant men.

Barriers to TB care for rural-to-urban migrant TB patients in Shanghai: a qualitative study.

OBJECTIVE: To understand barriers to tuberculosis (TB) care among migrant TB patients in Shanghai after the introduction of the TB-free treatment policy which has applied to migrants since 2003, and to provide policy recommendations to improve TB control in migrant populations in big cities. METHODS: In-depth interviews were conducted with 34 migrant patients who registered on the Shanghai TB programme as new bacteria positive pulmonary TB cases. Patients were purposively selected across six districts of Shanghai to give a balance of gender and TB treatment phase. RESULTS: Financial constraints were reported as the biggest barriers to TB service among migrant patients. Many migrant patients experienced high medical costs both before and after their TB diagnosis. The government free treatment policy only covered a small fraction of patients' total costs. However, respondents tended to stay in Shanghai for treatment because their families were in Shanghai, they were more confident with the quality of medical care there or they felt they could not earn cash at home. Migrant patients had a limited knowledge of TB and the free TB treatment policy, and reported being laid off from work or avoided after having TB. CONCLUSIONS: Health system problems caused the biggest barrier to migrant patients' access to TB care. The free treatment policy alone has little, if any, effect in reducing migrant patients' financial stress: it is also essential to provide social welfare, including living subsidies, for poor migrant TB patients.
