What lessons can be drawn from tuberculosis (TB) control in China in the 1990s? An analysis from a health system perspective

Feasibility of eliminating tuberculosis by shortening the diagnostic delay: A retrospective analysis and modelling study in China during the pre-COVID-19 era

Objective

Delays in the diagnosis and treatment of pulmonary tuberculosis (PTB) can increase the risk of transmission, thereby posing a significant risk to public health. Early diagnosis is considered to play a crucial role in eliminating TB. Rapid testing, active case finding, and health education are effective strategies for reducing tuberculosis diagnosis delays (TDDs). This study aimed to quantitatively compare the impact of reducing the TDD on incidence rates among student and non-student groups, thus exploring the efficacy of shortening the TDD for ending the TB epidemic and providing a reference for achieving the target incidence rate for ending TB.

Methods

We used unsupervised hierarchical clustering analysis and non-parametric tests to characterize the epidemiological characteristics of TDD. Additionally, a dynamic transmission model was used to quantify the impact of shortening the TDD on the incidence rates of TB among the two groups.

Results

There was an initial increase in the TDD, followed by a decrease. Longer TDDs were observed in the northeastern region of China. Farmers, middle and high school students, middle-aged, elderly individuals and males exhibited relatively longer TDDs. A significant reduction in the incidence rate of PTB was observed when the TDD was decreased by 50 %. However, only reducing the TDD among non-students could achieve the goal of ending TB (i.e., achieving a minimum reduction of 63.00 %).

Conclusions

TDD remains a serious risk to public health, and non-students were shown to experience longer TDD. Shortening the TDD is crucial for reducing the incidence rates of TB, especially among non-students. It is essential to develop a highly sensitive and effective system for eliminating TB among non-students.

Roadmap for ending TB in China by 2035: The challenges and strategies

Tuberculosis (TB) is one of the top ten causes of death worldwide, taking the lives of over a million people annually. In addition to being a serious health issue, TB is also closely linked to eradicating poverty according to the Sustainable Development Goals (SDGs) of the United Nations (UN). All UN members have committed to ending the TB epidemic by 2030. China has one of the highest TB loads worldwide, ranking third in the world on many TB burden indices. The national strategy for TB control is aimed at creating a collaborative network and integrating TB treatment into the medical system. According to the WHO's global TB report, China is expected to have 748,000 new cases of TB in 2022 and an incidence of 52 cases per 100,000 people. Ending TB remains a huge challenge and requires comprehensive control strategies in China. In this work, we have discussed the challenges of TB prevention and control in China and proposed specific measures to end TB.

The Progress of Global Antimicrobial Resistance Governance and Its Implication to China: A Review

China has great potential for engaging in global actions on antimicrobial resistance (AMR) control. This study aims to summarize the process of global AMR governance and provide relevant policy recommendations on how China could take more initiative in the global AMR governance. We searched for academic articles and official document published or issued before December 2020 in e-journal databases, official websites of major organizations, and the relevant national ministries. This review revealed that global action on AMR control has experienced three stages: (1) The beginning stage (1980s and 1990s) when actions were mainly sponsored by high-income countries and AMR surveillance was focused on hospitals; (2) The rapid development stage (2000-2010) when global AMR governance began to concentrate on joint actions in multi-sectors, and developing countries were gradually involved in global actions; (3) The comprehensive stage (2011 to present) when global actions on AMR have covered various fields in different countries. China's AMR governance has fallen behind at the beginning but recently began to catch up with the global trend. The central government should take a far-fetched view, act decisively and positively towards the global efforts of addressing AMR to play a more active and greater role on the international stage.

Process evaluation of E-learning in continuing medical education: evidence from the China-Gates Foundation Tuberculosis Control Program

Background

E-learning is a growing phenomenon which provides a unique opportunity to address the challenges in continuing medical education (CME). The China-Gates Foundation Tuberculosis (TB) Control Program implemented online training for TB health workers in three provinces of China. We aim to evaluate the implementation of E-learning CME programs, analyse the barriers and facilitators during the implementation process, and to provide policy recommendations.

Methods

Routine monitoring data were collected through the project office from December 2017 to June 2019. In-depth interviews, focus group discussion with project management personnel, teachers, and trainees (n = 78), and staff survey (baseline n = 555, final n = 757) were conducted in selected pilot areas at the provincial, municipal, and county/district levels in the three project provinces (Zhejiang, Jilin, and Ningxia). Descriptive analysis of quantitative data summarized the participation, registration, and certification rates for training activities. Thematic approach was used for qualitative data analysis.

Results

By the end of June 2019, the national and provincial remote training platforms had organized 98 synchronous learning activities, with an average of 173.2 people [standard deviation (SD) = 49.8] per online training session, 163.3 people (SD = 41.2) per online case discussion. In the pilot area, 64.5% of TB health workforce registered the asynchronous learning platform, and 50.1% obtained their professional certifications. Participants agreed that E-learning CME was more economical, has better content as well as more flexible work schedules. However, the project still faced challenges in terms of unmet learning needs, disorganized governance, insufficient hardware and software, unsupported environment, and lack of incentive mechanisms.

Conclusions

Our results suggested that it’s feasible to conduct large scale E-learning CME activities in the three project provinces of China. Training content and format are key facilitators of the program implementation, while the matching of training supply and demand, organizational coordination, internet technology, motivations, and sustainability are key barriers.

Barriers to prompt TB diagnosis-a comparative study between northern Malawi and eastern rural China

Background

Tuberculosis (TB) case detection in China has improved remarkably, partly benefiting from the reducing delay to TB care, whereas the timeliness of TB care in Malawi remains problematic.

Methods

This study investigates barriers hindering timely TB diagnosis in Malawi and China, and attempts to share the experience in high burden countries. A cross-sectional study on TB diagnostic delay was conducted among 254 Malawian and 146 Chinese TB patients.

Results

The medians of patient's delays were 22 and 20 days (p>0.05), and provider delays were 12 and 11.5 days (p>0.05) in Malawi and China, respectively. Malawian patients had a higher proportion (72.05% vs 67.12%) of patient's delay longer than 14 days (p=0.042), which was significantly associated with initial visits to lower-level health providers in the villages (aOR=1.989, 95% CI: 1.075-3.682), and patients conducting casual/piece work (aOR=3.318, 95% CI: 1.228-8.964). Initial healthcare visits at village level also led to longer provider delay in both Malawi (aOR=2.055, 1.211-3.487) and China (aOR=5.627, 2.218-14.276).

Conclusion

Establishing a good communication and referral mechanism between different levels of health facilities is crucial to timely TB diagnosis. China's experience on pro-poor interventions could be useful to its Malawian counterpart and other similar settings with high TB burden.

What do we know about the needs and challenges of health systems? A scoping review of the international literature

BACKGROUND

While there is an extensive literature on Health System (HS) strengthening and on the performance of specific HSs, there are few exhaustive syntheses of the challenges HSs are facing worldwide. This paper reports the findings of a scoping review aiming to classify the challenges of HSs investigated in the scientific literature. Specifically, it determines the kind of research conducted on HS challenges, where it was performed, in which health sectors and on which populations. It also identifies the types of challenge described the most and how they varied across countries.

METHODS

We searched 8 databases to identify scientific papers published in English, French and Italian between January 2000 and April 2016 that addressed HS needs and challenges. The challenges reported in the articles were classified using van Olmen et al.'s dynamic HS framework. Countries were classified using the Human Development Index (HDI). Our analyses relied on descriptive statistics and qualitative content analysis.

RESULTS

292 articles were included in our scoping review. 33.6% of these articles were empirical studies and 60.1% were specific to countries falling within the very high HDI category, in particular the United States. The most frequently researched sectors were mental health (41%), infectious diseases (12%) and primary care (11%). The most frequently studied target populations included elderly people (23%), people living in remote or poor areas (21%), visible or ethnic minorities (15%), and children and adolescents (15%). The most frequently reported challenges related to human resources (22%), leadership and governance (21%) and health service delivery (24%). While health service delivery challenges were more often examined in countries within the very high HDI category, human resources challenges attracted more attention within the low HDI category.

CONCLUSIONS

This scoping review provides a quantitative description of the available evidence on HS challenges and a qualitative exploration of the dynamic relationships that HS components entertain. While health services research is increasingly concerned about the way HSs can adopt innovations, little is known about the system-level challenges that innovations should address in the first place. Within this perspective, four key lessons are drawn as well as three knowledge gaps.

The effect of NCMS on catastrophic health expenditure and impoverishment from tuberculosis care in China

Background

Health expenditure for tuberculosis (TB) care often pushes households into catastrophe and poverty. New Cooperative Medical Scheme (NCMS) aims to protect households from catastrophic health expenditure (CHE) and impoverishment in rural China. This article assesses the effect of NCMS on relieving CHE and impoverishment from TB care in rural China.

Methods

Three hundred fourty-seven TB cases are included in the analysis. We analyze the incidence and intensity of CHE and poverty, and assess the protective effect of NCMS by comparing the CHE and impoverishment before and after reimbursement.

Results

After out-of-pocket (OOP) payment for TB care, 16.1 % of non-poor fall below poverty line. The NCMS reduces the incidence of CHE and impoverishment by 11.5 % and 7.3 %. After reimbursement, 46.7 % of the households still experience CHE and 35.4 % are below the poverty line. The NCMS relieves the mean gap, mean positive gap, poverty gap and normalized positive gap by 44.5 %, 51.0 %, US$115.8 and 31.6 % respectively.

Conclusions

The NCMS has partial effect on protecting households from CHE and impoverishment from TB care. The limited protection could be enhanced by redesigning benefit coverage to improve the “height” of the NCMS and representing fee-for-service with alternative payment mechanisms.

Factors that associated with TB patient admission rate and TB inpatient service cost: a cross-sectional study in China

Background

China has recently adopted the “TB designated hospital model” to improve the quality of tuberculosis (TB) treatment and patient management. Considering that inpatient service often results in high patient financial burden, and therefore influences patient adherence to treatment, it is critical to better understand the TB patient admission rate and TB inpatient service cost, as well as their influential factors in this new model.

Methods

Quantitative and qualitative studies were conducted in two cities, Hanzhong in Shaanxi Province and Zhenjiang in Jiangsu Province, in China. Quantitative data were obtained from a sample survey of 533 TB patients and TB inpatient records from 2010–2012 in six county designated hospitals. Qualitative information was obtained through interviews with key stakeholders (40 key informant interviews, 14 focus group discussions) and reviews of health policy documents in study areas. Both univariate and multivariate statistical analyses were applied for the quantitative analysis, and the thematic framework approach was applied for the qualitative analysis.

Results

The TB patient admission rates in Zhenjiang and Hanzhong were 54.8 and 55.9 %, respectively. Qualitative analyses revealed that financial incentives, misunderstanding of infectious disease control and failure of health insurance regulations were the key factors associated with the admission rates and medical costs. Quantitative analyses found differences in hospitalization rate existed among patients with different health insurance and patients from different counties. Average medical costs for TB inpatients in Jurong and Zhenba were 7,215 CNY and 4,644 CNY, which was higher than the 5,500 CNY and 3,800 CNY limits set by the New Rural Cooperative Medical System. No differences in medical cost or length of stay were found between patients with and without comorbidities in county-level hospitals.

Conclusions

TB patient admission rates and inpatient service costs were relatively high. Studies of related factors indicated that a package of interventions, including health education programs, reform of health insurance regulations and improvement of TB treatment guidelines, are urgently required to ensure that TB patients receive appropriate care.

Access to Bacteriologic-Based Diagnosis in Smear Positive Retreatment Tuberculosis Patients in Rural China: A Cross-Sectional Study in Three Geographic Varied Provinces

Objective

To determine factors influencing the utilization and accessibility to bacteriologic-based tuberculosis (TB) diagnosis among sputum smear positive (SS+) retreatment TB patients, and to develop strategies for improving the case detection rate of MDR-TB in rural China.

Study Design and Setting

A cross-sectional study of SS+ TB retreatment patients was conducted in eight counties from three provinces with different implementation period and strategy of MDR-TB program in China. Demographic and socioeconomic parameters were collected by self-reporting questionnaires. Sputum samples were collected and cultured by the laboratory of county-designated TB clinics and delivered to prefectural Centers for Disease Prevention and Control (CDC) labs for DST with 4 first-line anti-TB drugs.

Results

Among the 196 SS+ retreatment patients, 61.22% received culture tests during current treatment. Patients from more developed regions (OR = 24.0 and 3.6, 95% CI: 8.6–67.3 and 1.1–11.6), with better socio-economic status (OR = 3. 8, 95% CI: 1.3–10.7), who had multiple previous anti-TB treatments (OR = 5.0, 95% CI: 1.6–15.9), and who failed in the most recent anti-TB treatment (OR = 2.6, 95% CI: 1.0–6.4) were more likely to receive culture tests. The percentage of isolates resistant to any of first-line anti-TB drugs and MDR-TB were 50.0% (95% CI: 39.8%-60.2%) and 30.4% (95% CI: 21.0%-39.8%) respectively.

Conclusions

Retreatment SS+ TB patients, high risk MDR-TB population, had poor utilization of access to bacteriologic-based TB diagnosis, which is far from optimal. The next step of anti-TB strategy should be focused on how to make bacteriological-based diagnosis cheaper, safer and more maneuverable, and how to assure the DST-guided treatment for these high-risk TB patients.

Framework of behavioral indicators evaluating TB health promotion outcomes: a modified Delphi study of TB policymakers and health workers

Background

Although TB health promotion directed at policy makers and healthcare workers (HCWs) is considered important to tuberculosis (TB) control, no indicators currently assess the impact of such promotional activities. This article is the second in a series of papers that seek to establish a framework of behavioral indicators for outcome evaluation of TB health promotion, using the Delphi method. In the first article, we sought to establish a framework of behavioral indicators for outcome evaluation of TB health promotion among TB suspects and patients. The objective of this second article is to present an indicator framework that can be used to assess behavioral outcomes of TB health promotion directed at policy makers and HCWs.

Methods

A two-round, modified Delphi method was used to establish the indicators. Sixteen experts who were knowledgeable and experienced in the field of TB control were consulted in Delphi surveys. A questionnaire was developed following 4 steps, and involved ranking indicators on a five-point Likert scale. The consensus level was 70 %. Median, mode, and Coefficient of variation (CV) were used to describe expert responses. An authority coefficient (Cr) was used to assess the degree of each expert’s authority.

Results

Consensus was achieved following the two survey rounds and several iterations among the experts. For TB health-promotion activities directed at policymakers, the experts reached consensus on 2 domains (“Resource inputs” and “Policymaking and monitoring behaviors”), 4 subdomains (“Human resources” among others), and 13 indicators (“Human resources per 100,000 person” among others). For TB health-promotion activities directed at HCWs, the experts reached consensus on 5 domains (“Self-protective behaviors” among others), 6 sub-domains (“Preventing infection” among others), and 15 indicators (“Average hours of daily workplace disinfection by ultraviolet radiation” among others).

Conclusions

This study identified a conceptual framework of core behavioral indicators to evaluate TB health-promotion activities directed at policymakers and HCWs involved in TB control. Validation in other parts of the world could lead to global consensus on behavioral indicators to evaluate TB health promotion targeted at policymakers and HCWs.

Barriers to hospital and tuberculosis programme collaboration in China: context matters

BACKGROUND

In many developing countries, programmes for 'diseases of social importance', such as tuberculosis (TB), have traditionally been organised as vertical services. In most of China, general hospitals are required to report and refer suspected TB cases to the TB programme for standardised diagnosis and treatment. General hospitals are the major contacts of health services for the TB patients. Despite the implementation of public-public/private mix, directly observed treatment, short-course, TB reporting and referral still remain a challenge.

OBJECTIVE

This study aims to identify barriers to the collaboration between the TB programme and general hospitals in China.

DESIGN

This is a qualitative study conducted in two purposefully selected counties in China: one in Zhejiang, a more affluent eastern province, and another in Guangxi, a poorer southwest province. Sixteen in-depth interviews were conducted and triangulated with document review and field notes. An open systems perspective, which views organisations as social systems, was adopted.

RESULTS

The most perceived problem appeared to be untimely reporting and referral associated with non-standardised prescriptions and hospitalisation by the general hospitals. These problems could be due to the financial incentives of the general hospitals, poor supervision from the TB programme to general hospitals, and lack of technical support from the TB programme to the general hospitals. However, contextual factors, such as different funding natures of different organisations, the prevalent medical and relationship cultures, and limited TB funding, could constrain the processes of collaboration between the TB programme and the general hospitals.

CONCLUSIONS

The challenges in the TB programme and general hospital collaboration are rooted in the context. Improving collaboration should reduce the potential mistrust of the two organisations by aligning their interests, improving training, and improving supervision of TB control in the hospitals. In particular, effective regulatory mechanisms are crucial to alleviate the negative impact of the contextual factors and ensure smooth collaboration.

Tuberculosis control in China: use of modelling to develop targets and policies

It is unclear if current programmes in China can achieve the post-2015 global targets for tuberculosis – 50% reduction in incidence and a 75% reduction in mortality by 2025. Chinese policy-makers need to maintain the recent decline in the prevalence of tuberculosis, while revising control policies to cope with an epidemic of drug-resistant tuberculosis and the effects of ongoing health reform. Health reforms are expected to shift patients from tuberculosis dispensaries to designated hospitals. We developed a mathematical model of tuberculosis control in China to help set appropriate targets and prioritize interventions that might be implemented in the next 10 years. This model indicates that, even under the most optimistic scenario – improved treatment in tuberculosis dispensaries, introduction of a new effective regimen for the treatment of drug-susceptible tuberculosis and optimal care of cases of multidrug-resistant tuberculosis – the current global targets for tuberculosis are unlikely to be reached. However, reductions in the incidence of multidrug-resistant tuberculosis should be feasible. We conclude that a shift of patients from tuberculosis dispensaries to designated hospitals is likely to hamper efforts at tuberculosis control if cure rates in the designated hospitals cannot be maintained at a high level. Our results can inform the planning of tuberculosis control in China.

Views of professional nurses regarding low tuberculosis cure rate in Greater Giyani Municipality, Limpopo Province

BACKGROUND

Management of patients suffering from tuberculosis (TB) after discharge from hospital plays a critical role in the cure rate of TB. Despite interventions developed by the World Health Organization (WHO) to improve the cure rate, TB remains a worldwide health problem.

OBJECTIVE

The purpose of the study was to explore and describe the views of professional nurses regarding the low TB cure rate in primary healthcare facilities of Greater Giyani Municipality in Limpopo Province, South Africa, with the aim of determining strategies that can be used to improve this low rate.

METHOD

This study was qualitative, exploratory, descriptive and contextual in nature. The population consisted of professional nurses working in primary healthcare facilities within Greater Giyani Municipality, which has a TB cure rate below the national target of 85%. Data gathering was through individual face-to-face interviews using an interview guide. Open-coding was used to analyse the data in this study.

RESULTS

The theme that emerged from data was ‘factors contributing to low TB cure rate’. This theme was supported by the following sub-themes: poor referral system, lack of knowledge about TB and its treatment, stigma attached to TB, and cultural and religious beliefs. The professional nurses suggested counselling of TB patients upon diagnosis, advice about patients’ responsibilities and the involvement of family members.

CONCLUSION

The involvement of community stakeholders in TB prevention, health promotion and education activities devoted to disease spread and cure is vital so that the stigma attached to TB can be eliminated. TB education and awareness programmes should be included in the curriculum of primary schools.

Patient care pathways under the model of integrating tuberculosis service with general hospitals in China

OBJECTIVE

To report care pathways of tuberculosis (TB) patients under the integrated model, where TB clinical service is provided by a general hospital instead of the TB dispensary, with the aim of providing policy recommendations for TB care reforms in China.

METHODS

Six counties implementing the integrated model were randomly selected, and 50 TB patients in each county participated in a questionnaire survey.

RESULTS

Of the 301 participants, 82 visited only the TB designated hospital. A patient visited a median of two health providers in total. The median external provider delay and internal provider delay were 1 and 0 day, respectively. The median out-of-pocket medical costs were US$379 in total; US$293 in the TB units and US$0 in other health units in the TB designated hospital. Logistic regression analyses suggested that patients who visited the primary care facilities first tended to have longer external delays (OR = 5.71) than patients who visited the other hospitals (OR = 10.16).

CONCLUSION

The integrated model is promising as it reported relatively fewer patient pathways and shorter delays than the dispensary model. However, the integrated model did not reduce patient out-of-pocket costs.

The political economy of healthcare reform in China: negotiating public and private

China's healthcare system is experiencing significant growth from expanded government-backed insurance, greater public-sector spending on hospitals, and the introduction of private insurance and for-profit clinics. An incremental reform process has sought to develop market incentives for medical innovation and liberalize physician compensation and hospital finance while continuing to keep basic care affordable to a large population that pays for many components of care out-of-pocket. Additional changes presently under consideration by policymakers are likely to further restructure insurance and the delivery of care and will alter competitive dynamics in major healthcare industries, notably pharmaceuticals, medical devices, and diagnostic testing. This article describes the institutional history of China's healthcare system and identifies dilemmas emerging as the country negotiates divisions between public and private in healthcare. Building on this analysis, the article considers opportunities for public-private partnerships and greater systems integration to reconcile otherwise incommensurable approaches to rewarding innovation and improving access. The article concludes with observations on the public function of health insurance and its significance to further development of China's healthcare system.

Tuberculosis management practices by private practitioners in Andhra Pradesh, India

Setting

Private medical practitioners in Visakhapatnam district, Andhra Pradesh, India.

Objectives

To evaluate self-reported TB diagnostic and treatment practices amongst private medical practitioners against benchmark practices articulated in the International Standards of Tuberculosis Care (ISTC), and factors associated with compliance with ISTC.

Design

Cross- sectional survey using semi-structured interviews.

Results

Of 296 randomly selected private practitioners, 201 (68%) were assessed for compliance to ISTC diagnostic and treatment standards in TB management. Only 11 (6%) followed a combination of 6 diagnostic standards together and only 1 followed a combination of all seven treatment standards together. There were 28 (14%) private practitioners who complied with a combination of three core ISTC (cough for tuberculosis suspects, sputum smear examination and use of standardized treatment). Higher ISTC compliance was associated with caring for more than 20 TB patients annually, prior sensitization to TB control guidelines, and practice of alternate systems of medicine.

Conclusion

Few private practitioners in Visakhapatnam, India reported TB diagnostic and treatment practices that met ISTC. Better engagement of the private sector is urgently required to improve TB management practices and to prevent diagnostic delay and drug resistance.

Views of health service providers on obstacles to tuberculosis control in Ghana

Background

Although Ghana does not fall into the category of those countries which have a high burden of tuberculosis (TB), the disease does present considerable economic and health limitations to individuals infected with, and affected by, the disease, as well as to the health system in general. Despite this fact, insufficient studies have been done on the key barriers to controlling the disease. This paper presents results from an exploratory study on the constraints of controlling TB in Ghana based on the opinions of health service providers.

Methods

In-depth interviews were conducted with frontline health workers involved in TB control in the country. Participants were purposively selected from a pool of national and regional, and district and facility level coordinators of the National Tuberculosis Control Programme (NTP). One key informant was also selected from an international non-governmental organisation (NGO) involved in TB-related activities in Ghana. Observations were utilised to complement the study. Data were analysed inductively.

Results

Respondents identified the following as being constraints to TB control: clinical complication, bottlenecks in funding administration, quality of physical infrastructure, competition for attention and funding, unsatisfactory coordination between TB and HIV control programmes, a poor public-private partnership, and weak monitoring and evaluation of interventions.

Conclusions

This paper provides evidence of some key barriers to TB control. The barriers, as reported, were generally health system-based. Although this list of barriers is not exhaustive, it would be useful to take them into account when planning for TB control, thus adopting a more rounded approach to TB management in the country. As well as that, further studies should be done to explore patients’ views on health service-related barriers to TB control.

Comparing patient care seeking pathways in three models of hospital and TB programme collaboration in China

Background

Public hospitals in China play an important role in tuberculosis (TB) control. Three models of hospital and TB control exist in China. The dispensary model is the most common one in which a TB dispensary provides both clinical and public health care. The specialist model is similar to the former except that a specialist TB hospital is located in the same area. The specialist hospital should treat only complicated TB cases but it also treats simple cases in practice. The integrated model is a new development to integrate TB service in public hospitals. Patients were diagnosed, treated and followed up in this public hospital in this model while the TB dispensary provides public health service as case reporting and mass education. This study aims to compare patient care seeking pathways under the three models, and to provide policy recommendation for the TB control system reform in China.

Methods

Six sites, two in each model, were selected across four provinces, with 293 newly treated uncomplicated TB patients being randomly selected.

Results

The majority (68%) of TB patients were diagnosed in hospitals. Patients in the integrated model presented the simplest care seeking pathways, with the least number of providers visited (2.2), shortest treatment delays (2 days) and the least medical expenditure (2729RMB/401USD). On the contrary, patients in the specialist model had the highest number of provider visits (4), longest treatment delays (23 days) and the highest medical expenditure (11626RMB/1710USD). Logistic regression suggested that patients who were hospitalised tended to have longer treatment delays and higher medical expenditure.

Conclusion

Specialist hospital treating uncomplicated cases not using the standard regimens posed a threat to TB control. The integrated model has shortened patient treatment pathways, and reduced patient costs; therefore, it could be considered as the direction for future reform of China’s TB control system.

Engaging sub-national governments in addressing health equities: challenges and opportunities in China's health system reform

China's current health system reform (HSR) is striving to resolve deep inequities in health outcomes. Achieving this goal is difficult not only because of continuously increasing income disparities in China but also because of weaknesses in healthcare financing and delivery at the local level. We explore to what extent sub-national governments, which are largely responsible for health financing in China, are addressing health inequities. We describe the recent trend in health inequalities in China, and analyse government expenditure on health in the context of China's decentralization and intergovernmental model to assess whether national, provincial and sub-provincial public resource allocations and local government accountability relationships are aligned with this goal. Our analysis reveals that government expenditure on health at sub-national levels, which accounts for ∼90% of total government expenditure on health, is increasingly regressive across provinces, and across prefectures within provinces. Increasing inequity in public expenditure at sub-national levels indicates that resources and responsibilities at sub-national levels in China are not well aligned with national priorities. China's HSR would benefit from complementary measures to improve the governance and financing of public service delivery. We discuss the existing weaknesses in local governance and suggest possible approaches to better align the responsibilities and capacity of sub-national governments with national policies, standards, laws and regulations, therefore ensuring local-level implementation and enforcement. Drawing on China's institutional framework and ongoing reform pilots, we present possible approaches to: (1) consolidate key health financing responsibilities at the provincial level and strengthen the accountability of provincial governments, (2) define targets for expenditure on primary health care, outputs and outcomes for each province and (3) use independent sources to monitor and evaluate policy implementation and service delivery and to strengthen sub-national government performance management.

Factors associated with delayed tuberculosis diagnosis in China

BACKGROUND

Delays in the diagnosis of tuberculosis reflect a lack of access to care, and contribute to ongoing tuberculosis transmission in the community. The objective of this study was to evaluate the delay in tuberculosis testing and the associated risk factors in Shanghai, Shandong and Sichuan provinces in China.

METHODS

A prospective cohort study of 765 culture-positive pulmonary tuberculosis patients registered between December 2006 and December 2008. The delay between the onset of symptoms and tuberculosis diagnosis testing and patient information were recorded in a questionnaire and analysed.

RESULTS

The median delay was 36 days and was significantly shorter in patients from Shanghai compared with other places (30 vs. 42 days, P < 0.001). Multivariate analysis revealed that cough in Shanghai patients, lowest income level, being married and presenting expectoration in Shandong and Sichuan patients, were associated with a delay in the diagnosis testing of tuberculosis of >30 days. The only factor associated with a delay of >90 days was, in Shandong and Sichuan provinces only, female gender. The presence of other pulmonary symptoms like haemoptysis and loss of weight, fever and chills could shorten these delays.

CONCLUSION

Efforts to shorten delays in the diagnosis of tuberculosis must target vulnerable populations. The non-specific symptom of cough is a risk factor associated with longer delays. Training for healthcare workers in areas with a high incidence of tuberculosis, where a delayed diagnosis in coughers may enhance tuberculosis transmission in the community, is of paramount importance.

Urbanization and Infectious Diseases: General Principles, Historical Perspectives, and Contemporary Challenges

In 2009, a major demographic line was crossed: for the first time in history, the majority of the world population lived in cities rather than in towns and countryside (Fig. 4.1). This shift has been occurring over the past 100 years, with the most rapid rate of urban growth occurring over in the latter half of the twentieth century. Urban centers in the more developed regions of the world (i.e., North America, Australia, New Zealand, and Europe) experienced earlier growth in the 1920s–1950s, and since then, the rapid rate of urban growth has been concentrated in the cities and towns of developing nations [1].

Factors influencing integration of TB services in general hospitals in two regions of China: a qualitative study

BACKGROUND

In the majority of China, the Centre for Disease Control (CDC) at the county level provides both clinical and public health care for TB cases, with hospitals and other health facilities referring suspected TB cases to the CDC. In recent years, an integrated model has emerged, where the CDC remains the basic management unit for TB control, while a general hospital is designated to provide clinical care for TB patients. This study aims to explore the factors that influence the integration of TB services in general hospitals and generate knowledge to aid the scale-up of integration of TB services in China.

METHODS

This study adopted a qualitative approach using interviews from sites in East and West China. Analysis was conducted using a thematic framework approach.

RESULTS

The more prosperous site in East China was more coordinated and thus had a better method of resource allocation and more patient-orientated service, compared with the poorer site in the West. The development of public health organizations appeared to influence how effectively integration occurred. An understanding from staff that hospitals had better capacity to treat TB patients than CDCs was a strong rationale for integration. However, the economic and political interests might act as a barrier to effective integration. Both sites shared the same challenges of attracting and retaining a skilled workforce for the TB services. The role of the health bureau was more directive in the Western site, while a more participatory and collaborative approach was adopted in the Eastern site.

CONCLUSION

The process of integration identifies similarities and differences between sites in more affluent East China and poorer West China. Integration of TB services in the hospitals needs to address the challenges of stakeholder motivations and resource allocation. Effective inter-organizational collaboration could help to improve the efficiency and quality of TB service.

Communicable disease control in China: From Mao to now

China's progress on communicable disease control (CDC) in the 30 years after establishment of the People's Republic in 1949 is widely regarded as remarkable. Life expectancy soared by around 30 years, infant mortality plummeted and smallpox, sexually transmitted diseases and many other infections were either eliminated or decreased massively in incidence, largely as a result of CDC. By the mid-1970s, China was already undergoing the epidemiologic transition, years ahead of other nations of similar economic status. These early successes can be attributed to population mobilization, mass campaigns and a focus on sanitation, hygiene, clean water and clean delivery, and occurred despite political instability and slow economic progress. The 10-year Cultural Revolution from 1966 brought many hardships, but also clinical care and continuing public health programs to the masses through community-funded medical schemes and the establishment of community-based health workers. These people-focused approaches broke down with China's market reforms from 1980. Village doctors turned to private practice as community funding ceased, and the attention paid to rural public health declined. CDC relied on vertical programs, some of them successful (such as elimination of lymphatic filariasis and child immunisation), but others (such as control of schistosomiasis and tuberculosis) demonstrating only intermittent progress due to failed strategies or reliance on support by the poorest governments and health workers, who could not or would not collaborate. In addition, China's laissez-faire approach to public health placed it at great risk, as evidenced by the outbreak in 2003 of the Severe Acute Respiratory Syndrome. Since then, major changes to disease reporting, the priority given to CDC including through major new domestic resources and reform of China's health system offer encouragement for CDC. While decentralized funding and varying quality diagnosis, reporting and treatment of infectious diseases remain major challenges, national priority on CDC in China is high.

A TUBERCULOSIS (TB) MODEL WITH UNDETECTED COMPARTMENT: AN APPLICATION TO CHINA

This article introduces a novel model that studies the major factors jeopardizing tuberculosis (TB) control programme in China. A previously developed two-strain TB model is augmented with a class of individuals not registered under the TB control programme. The paper investigates the basic reproduction number and proves the global stability of the disease-free equilibrium. The presence of three endemic equilibria is established in the model. With the help of numerical simulations, a comparative study has been performed to test the validity of the model presented here to the real data available from the Ministry of Health of the People's Republic of China. Sensitivity and elasticity analysis give the key parameters that would govern successful TB control in China.

Patient medical costs for tuberculosis treatment and impact on adherence in China: a systematic review

Background

Charging for tuberculosis (TB) treatment could reduce completion rates, particularly in the poor. We identified and synthesised studies that measure costs of TB treatment, estimates of adherence and the potential impact of charging on treatment completion in China.

Methods

Inclusion criteria were primary research studies, including surveys and studies using qualitative methods, conducted in mainland China. We searched MEDLINE, PUBMED, EMBASE, Science Direct, HEED, CNKI to June 2010; and web pages of relevant Chinese and international organisations. Cost estimates were extracted, transformed, and expressed in absolute values and as a percentage of household income.

Results

Low income patients, defined at household or district level, pay a total of US$ 149 to 724 (RMB 1241 to 5228) for medical costs for a treatment course; as a percentage of annual household income, estimates range from 42% to 119%. One national survey showed 73% of TB patients at the time of the survey had interrupted or suspended treatment, and estimates from 9 smaller more recent studies showed that the proportion of patients at the time of the survey who had run out of drugs or were not taking them ranged from 3 to 25%. Synthesis of surveys and qualitative research indicate that cost is the most cited reason for default.

Conclusions

Despite a policy of free drug treatment for TB in China, health services charge all income groups, and costs are high. Adherence measured in cross sectional surveys is often low, and the cumulative failure to adhere is likely to be much higher. These findings may be relevant to those concerned with the development and spread of multi-drug resistant TB. New strategies need to take this into account and ensure patient adherence.

Risk factors for non-cure among new sputum smear positive tuberculosis patients treated in tuberculosis dispensaries in Yunnan, China

Background

Yunnan province in China has a high tuberculosis (TB) burden. Cure rates in general are high, but they were below the target of 85% in 26 out of 129 counties in 2005. In these 26 counties we assessed which patient-related and treatment-related factors were associated with non-cure.

Methods

We conducted a prospective cohort study. Smear positive pulmonary TB patients treated at the local Center for Disease Control and Prevention (CDC) were interviewed before start of treatment and during the fifth month of treatment using structured questionnaires. Information on treatment outcome was extracted from patient records. Patients cured at the end of treatment were compared to patients with unsuccessful treatment outcomes (failure, default, and death).

Results

A total of 841 patients were registered between January-June 2007 of which 792 (94%) were cured. Independent risk factors for non-cure were having a low income (<3000 RMB per year), not having medical insurance, a delay in health care seeking >30 days, a positive smear test result two months after start of treatment, not being aware of the need to go to the CDC for medical follow up during treatment, and not seeing the need for treatment observation.

Conclusion

Reducing the financial burden of TB disease and providing health education to improve compliance with treatment could increase the proportion of patients with successful treatment outcomes.

Extensively Drug-Resistant Tuberculosis: A Sign of the Times and an Impetus for Antimicrobial Discovery

Mycobacterium tuberculosis is an extraordinarily successful human pathogen, infecting one-third of the world's population and causing nearly two million deaths each year. In this article, current trends in worldwide tuberculosis (TB) incidence, prevalence, and mortality are discussed along with standard TB treatment regimens, characteristics of first-line and second-line anti-tuberculosis drugs, and mechanisms of antibiotic resistance. The global TB emergency has been further exacerbated by extensively drug-resistant (XDR) TB strains that are resistant to our best antibiotics and very difficult to treat. This review also focuses on the emergence of XDR-TB strains, the global health impact, and existing treatment options and outcomes for XDR-TB disease. Finally, this review briefly describes new anti-tuberculosis drugs currently in Phase II clinical evaluations and the impetus for discovering new antibacterial compounds to target drug-resistant M. tuberculosis and improve tuberculosis therapy.

Factors associated with health-seeking behavior among migrant workers in Beijing, China

BACKGROUND

Migrant workers are a unique phenomenon in the process of China's economic transformation. The household registration system classifies them as temporary residents in cities, putting them in a vulnerable state with an unfair share of urban infrastructure and social public welfare. The amount of pressure inflicted by migrant workers in Beijing, as one of the major migration destinations, is currently at a threshold. This study was designed to assess the factors associated with health-seeking behavior and to explore feasible solutions to the obstacles migrant workers in China faced with when accessing health-care.

METHODS

A sample of 2,478 migrant workers in Beijing was chosen by the multi-stage stratified cluster sampling method. A structured questionnaire survey was conducted via face-to-face interviews between investigators and subjects. The multilevel methodology (MLM) was used to demonstrate the independent effects of the explanatory variables on health seeking behavior in migrant workers.

RESULTS

The medical visitation rate of migrant workers within the past two weeks was 4.8%, which only accounted for 36.4% of those who were ill. Nearly one-third of the migrant workers chose self-medication (33.3%) or no measures (30.3%) while ill within the past two weeks. 19.7% of the sick migrants who should have been hospitalized failed to receive medical treatment within the past year. According to self-reported reasons, the high cost of health service was a significant obstacle to health-care access for 40.5% of the migrant workers who became sick. However, 94.0% of the migrant workers didn't have any insurance coverage in Beijing. The multilevel model analysis indicates that health-seeking behavior among migrants is significantly associated with their insurance coverage. Meanwhile, such factors as household monthly income per capita and working hours per day also affect the medical visitation rate of the migrant workers in Beijing.

CONCLUSION

This study assesses the influence of socio-demographic characteristics on the migrant workers' decision to seek health care services when they fall ill, and it also indicates that the current health service system discourages migrant workers from seeking appropriate care of good quality. Relevant policies of public medical insurance and assistance program should be vigorously implemented for providing affordable health care services to the migrants. Feasible measures need to be taken to reduce the health risks associated with current hygiene practices and equity should be assured in access to health care services among migrant workers.

Factors associated with low cure rate of tuberculosis in remote poor areas of Shaanxi Province, China: a case control study

Background

The directly observed therapy-short course (DOTS) strategy was introduced in Shaanxi province, China to improve tuberculosis (TB) control by means of improved case detection (target: > = 70%) and treatment success rates (target: > = 85%) in new smear positive (SS+) TB patients. At a provincial level the targets were both reached in 2005. However in 30 (28%) out of 107 counties of Shaanxi province the cure rate was below 85%. This study aimed to investigate patient and treatment characteristics associated with non-cure after tuberculosis (TB) treatment in these counties.

Methods

In this case-control study, new smear positive TB cases in 30 counties with a cure rate <85% were included. Cured patients were compared to non-cured patients using logistic regression analysis to assess determinants for non-cure.

Results

Of the 659 patients included, 153 (23.2%) did not have cure as treatment outcome. Interruption of treatment was most strongly associated with non-cure (OR = 8.7, 95% CI 3.9-18.4). Other independent risk factors were co-morbidity, low education level, lack of appetite as an initial symptom of TB disease, diagnosis of TB outside of the government TB control institutes, missing sputum re-examinations during treatment, and not having a treatment observer. Twenty-six percent of patients did not have a treatment observer. The non-cure rate was better for those with a doctor (odds ratio (OR) 0.38, 95% confidence interval (CI) 0.17-0.88) as treatment observer than for those with a family member (OR 0.62, 95%CI 0.37-1.03). The main reason for interrupted treatment mentioned by patients was presence of adverse effects during treatment (46.5%).

Conclusions

Interruption of treatment was most strongly associated with non-cure. Although treatment observation by medical staff is preferred, in order to diminish the proportion of patients who do not have a treatment observer and thereby reduce the proportion of patients who interrupt treatment, we suggest making it possible for family members, after sufficient training, to be treatment observers in remote areas where it is logistically difficult to have village doctors observe treatment for all patients.

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.

Adherence to anti-tuberculosis treatment among pulmonary tuberculosis patients: a qualitative and quantitative study

BACKGROUND

Tuberculosis (TB) patients have difficulty following a long-term treatment regimen. Efforts to improve treatment outcomes require better understanding of adherence as a complex behavioral issue and of the particular barriers to and facilitators of patient adherence.

METHODS

This study was carried out in Jiangsu Province of China with both quantitative and qualitative approaches. For the quantitative study, 780 sputum-smear positive TB patients consecutively registered since 2006 in 13 counties (districts) were queried with a structured questionnaire. Patients who had missed 10% of their total prescribed doses of TB drugs were deemed as non-adherent. Risks for non-adherence were estimated by computing odds ratios (ORs) and their 95% confidence intervals (95% CIs) using a logistic regression model. We also invited 20 TB patients and 10 local health workers for in-depth interviews. We then used content analysis based on this qualitative study to explore factors associated with non-adherence.

RESULTS

The proportion of non-adherence among 670 patients was 12.2%. Univariate analysis showed that patients, who were illiterate, divorced/widowed, lacked health insurance and were migrants, were more likely to be non-adherent. The crude ORs(95%CIs) were 2.38(1.37-4.13), 2.42(1.30-4.52), 1.89(1.07-3.32) and 1.98(1.03-3.83), respectively. The risk of non-adherence was lower among patients whose treatment was given under direct observation by village doctors or regular home visits by health workers, with ORs (95% CIs) of 0.19(0.10-0.36) and 0.23(0.10-0.51), respectively. In multivariate analysis, factors associated with non-adherence included illiteracy (OR: 2.42; 95% CI: 1.25-4.67) and direct observation by village doctors (OR: 0.23; 95% CI: 0.11-0.45). The in-depth interviews indicated that financial burdens and extra medical expenditures, adverse drug reactions, and social stigma were additional potential factors accounted for non-adherence.

CONCLUSION

More importance should be given to treatment adherence under the current TB control program. Heavy financial burdens, lack of social support, adverse drug reactions and personal factors are associated with non-adherence. Direct observation and regular home visits by health workers appear to reduce the risk of non-adherence. More patient-centered interventions and greater attention to structural barriers are needed to improve treatment adherence.

Direct observation and completion of treatment of tuberculosis in rural areas of China

AIMS

To analyse the current status of directly observed therapy (DOT) and completion of treatment of tuberculosis (TB) in two rural areas of China.

METHODS

Two rural counties with low DOT rates were deliberately selected as study sites. Face-to-face interviews were conducted by trained investigators with a structured questionnaire to investigate the characteristics of patients and the TB service that they had received. The associations between treatment completion and potential factors were estimated by computing odds ratios (ORs), as well as their 95% confidence intervals (CIs), from an unconditional logistic regression model.

RESULTS

Among 601 patients, 2.2% were treated with direct observation by health workers, 6.2% were supervised by family members, and 91.7% were treated with self-administered therapy. The treatment completion rate was found to be significantly associated with sputum smear test and adverse reaction to anti-tuberculosis drugs, but not with direct observation by health workers (OR 1.81, 95% CI 0.23-14.38) or by family members (OR 1.14, 95% CI 0.38-3.41). Frequent home visiting by health workers (!1 visit/month) could help to increase the completion rate (OR 3.15, 95% CI 1.30-7.63).

CONCLUSIONS

No significant difference was found in the rate of completion of TB treatment between direct observation and self-supervision groups in two rural areas with lower DOT coverage. How to build a feasible DOT strategy that is accepted by both patients and healthcare providers needs to be considered by policy-makers. Other elements apart from DOT are necessary to ensure a successful TB programme.

Why financial incentives did not reach the poor tuberculosis patients? A qualitative study of a Fidelis funded project in Shanxi, China

BACKGROUND

A project implemented in 50 counties of Shanxi province provided incentives to poor TB patients for their first trip to tuberculosis (TB) dispensaries. Incentives were also given to doctors for referring and supervising TB patients. A previous quantitative evaluation identified no improvement on TB case detection and management. This qualitative study was then conducted to explore reasons for project failure.

OBJECTIVE

To understand how the incentives were distributed to and viewed by their recipients and the implications for TB and health systems.

METHODS

Qualitative in-depth interviews were conducted with 32 TB patients, 13 village doctors, 12 village leaders, 8 TB doctors and 8 TB programme managers.

RESULTS

The study revealed a lack of operational tools on how to evaluate patients' economic status and how to publicise the incentives. As a result, patients did not know the level of incentives in advance and regarded the amount as inadequate. Patients faced a huge financial burden and a long delay in treating TB, dwarfing the benefits of travel incentives. The referral and case supervision incentives were not implemented. Doctors did not receive any referral and supervision incentives in addition to those already existing.

CONCLUSIONS

Strategies to address health system and TB programme issues should be implemented before or alongside financial incentives. Operational details and tools for any intervention should be developed, field-tested and revised prior to wide-scale use.

Emergence and control of infectious diseases in China

Infectious diseases remain the major causes of morbidity and mortality in China despite substantial progress in their control. China is a major contributor to the worldwide infectious disease burden because of its population size. The association of China with the rest of the world through travel and trade means that events in the country can affect distant populations. The ecological interaction of people with animals in China favours the emergence of new microbial threats. The public-health system has to be prepared to deal with the challenges of newly emerging infectious diseases and at the same time try to control existing diseases. To address the microbial threats, such as severe acute respiratory syndrome, the government has committed substantial resources to the implementation of new strategies, including the development of a real-time monitoring system as part of the infectious-disease surveillance. This strategy can serve as a model for worldwide surveillance and response to threats from infectious diseases.

Effects of smoking and solid-fuel use on COPD, lung cancer, and tuberculosis in China: a time-based, multiple risk factor, modelling study

BACKGROUND

Chronic obstructive pulmonary disease (COPD), lung cancer, and tuberculosis are three leading causes of death in China, where prevalences of smoking and solid-fuel use are also high. We aimed to predict the effects of risk-factor trends on COPD, lung cancer, and tuberculosis.

METHODS

We used representative data sources to estimate past trends in smoking and household solid-fuel use and to construct a range of future scenarios. We obtained the aetiological effects of risk factors on diseases from meta-analyses of epidemiological studies and from large studies in China. We modelled future COPD and lung cancer mortality and tuberculosis incidence, taking into account the accumulation of hazardous effects of risk factors on COPD and lung cancer over time, and dependency of the risk of tuberculosis infection on the prevalence of disease. We quantified the sensitivity of our results to methods and data choices.

FINDINGS

If smoking and solid-fuel use remain at current levels between 2003 and 2033, 65 million deaths from COPD and 18 million deaths from lung cancer are predicted in China; 82% of COPD deaths and 75% of lung cancer deaths will be attributable to the combined effects of smoking and solid-fuel use. Complete gradual cessation of smoking and solid-fuel use by 2033 could avoid 26 million deaths from COPD and 6.3 million deaths from lung cancer; interventions of intermediate magnitude would reduce deaths by 6-31% (COPD) and 8-26% (lung cancer). Complete cessation of smoking and solid-fuel use by 2033 would reduce the projected annual tuberculosis incidence in 2033 by 14-52% if 80% DOTS coverage is sustained, 27-62% if 50% coverage is sustained, or 33-71% if 20% coverage is sustained.

INTERPRETATION

Reducing smoking and solid-fuel use can substantially lower predictions of COPD and lung cancer burden and would contribute to effective tuberculosis control in China.

Gender difference in knowledge of tuberculosis and associated health-care seeking behaviors: a cross-sectional study in a rural area of China

BACKGROUND

Tuberculosis (TB) detection under the national TB control program in China follows passive case-finding guidelines, which could be influenced by the accessibility of health service and patient's health-care seeking behaviors. One intriguing topic is the correlation between men and women's knowledge on TB and their health-care seeking behaviors.

METHODS

Two cross-sectional studies were separately carried out in Yangzhong County, a rural area of China. One study, by using systematic sampling method, including 1,200 subjects, was conducted to investigate the TB knowledge among general population. Another study in the same source population screened 33,549 people aged 15 years or over among 20 stratified cluster-sampled villages for identifying prolonged cough patients at households and individual interviews were then carried out. Gender difference in the knowledge of TB and health-care seeking behaviors was analyzed particularly.

RESULTS

Among general population, only 16.0% (men 17.1% vs. women 15.0%) knew the prolonged cough with the duration of 3 weeks or longer was a symptom for suspicious TB. Fewer women than men knew the local appointed health facility for TB diagnosis and treatment as well as the current free TB service policy. Moreover, women were less likely to learn information about TB and share it with others on their own initiatives. On the contrary, after the onset of the prolonged cough, women (79.2%) were more likely to seek health-care than men (58.6%) did. However, a large part of women preferred to visit the lower level non-hospital health facilities at first such as village clinics and drugstores.

CONCLUSION

TB and DOTS program were not well known by rural Chinese. Gender issues should be considered to reduce diagnostic delay of TB and improve both men and women's access to qualified health facility for TB care. Strengthening awareness of TB and improving the accessibility of health-care service is essential in TB control strategy, especially under the current vertical TB control system.

Barriers to accessing TB diagnosis for rural-to-urban migrants with chronic cough in Chongqing, China: a mixed methods study

Background

China is facing a significant tuberculosis epidemic among rural-to-urban migrants, which poses a threat to TB control. This study aimed to understand the health seeking behaviour of and health systems responses to migrants and permanent urban residents suffering from chronic cough, in order to identify the factors influencing delays for both groups in receiving a TB diagnosis in urban China.

Methods

Combining a prospective cohort study of adult suspect TB patients and a qualitative study, the Piot model was used to analyze the health seeking behaviour of TB suspects among migrants and permanent urban residents, the factors influencing their decision and the responses by general health providers. Methods included a patient survey, focus group discussions with migrants in the general population, qualitative interviews with migrant and permanent resident TB suspects and TB patients as well as key stakeholders related to TB control and the management of migrants.

Results

Sixty eight percent of migrants delayed for more than two weeks before seeking care for symptoms suggestive of TB, compared to 54% of residents (p < 0.01). When they first decided to seek professional care, migrants were 1.5 times more likely than residents to use less expensive, community-level health services. Only 5% were ultimately referred to a TB dispensary. Major reasons for both patient and provider delay included lack of knowledge and mistrust of the TB control programme, lack of knowledge about TB (patients), and profit-seeking behaviour (providers). In the follow up survey, 61% of the migrants and 41% of the residents who still had symptoms gave up continuing to seek professional care, with a statistically significant difference between the two groups (p < 0.05).

Conclusion

Rural-to-urban migrants are more likely than permanent residents to delay in seeking care for symptoms suggestive of TB in urban Chongqing. 'Patient-' and 'provider-' related factors interact to pose barriers to TB diagnosis for migrants, including: low awareness, and poor knowledge among both the general public and TB suspects about TB as a disease and about the TB control programme; low financial capacity to pay for care and diagnostic tests; and inadequate use of diagnostic tests and referral to TB dispensaries by general health providers.

Adapting a generic tuberculosis control operational guideline and scaling it up in China: a qualitative case study

BACKGROUND

The TB operational guideline (the deskguide) is a detailed action guide for county TB doctors aiming to improve the quality of DOTS, while the China national TB policy guide is a guide to TB control that is comprehensive but lacks operational usability for frontline TB doctors. This study reports the process of deskguide adaptation, its scale-up and lessons learnt for policy implications.

METHODS

The deskguide was translated, reviewed, and revised in a working group process. Details of the eight adaptation steps are reported here. An operational study was embedded in the adaptation process. Two comparable prefectures were chosen as pilot and control sites in each of two participating provinces. In the pilot sites, the deskguide was used with the national policy guide in routine in-service training and supervisory trips; while in the control sites, only the national policy guide was used. In-depth interviews and focus groups were conducted with 16 county TB doctors, 16 township doctors, 17 village doctors, 63 TB patients and 57 patient family members. Following piloting, the deskguide was incorporated into the national TB guidelines for county TB dispensary use.

RESULTS

Qualitative research identified that the deskguide was useful in the daily practice of county TB doctors. Patients in the pilot sites had a better knowledge of TB and better treatment support compared with those in the control sites.

CONCLUSION

The adaptation process highlighted a number of general strategies to adapt generic guidelines into country specific ones: 1) local policy-makers and practitioners should have a leading role; 2) a systematic working process should be employed with capable focal persons; and 3) the guideline should be embedded within the current programmes so it is sustainable and replicable for further scale-up.

Presence and awareness of infectious disease among Chinese migrant workers

This cross-sectional study set out to identify the health status and health beliefs and behaviors with regard to TB and HIV-AIDS among 407 rural male migrant workers in China. Surveyed workers' awareness level for AIDS transmission was 67.7% and for TB transmission 56.8%. These workers had high rates of acute illness in the previous month (depression 18.3%, physical injury 16.3%, dermatological ailment 9.6%, respiratory infection 9.4%). One or more of the four symptoms of TB were found in 22.3% of the workers. Prevalent TB symptoms were associated with previously having had TB (chi-square = 69.98, p = .000) and having previously lived with a TB patient (F = 13.99, p = .000). The relative risk for having had TB if the worker had lived with someone with TB was 5.69 (chi-square 7.65, p = .006). Screening for TB symptoms, a history of having lived with someone with TB, or having previously had TB, has the potential to serve as a cost-effective and easy first-line TB screening among large mobile populations.

Beyond the medical-informational model: recasting the role of communication in tuberculosis control

Although communication has recently gained increased recognition in tuberculosis (TB) control programs, current thinking and practice remains boxed within the epistemological boundaries of the "bio-medical" model. The latter posits that information about transmission and care is crucial to promote early diagnosis and treatment. However, when populations confront a series of socio-cultural and structural barriers to access TB care, medical knowledge and awareness alone cannot effectively promote ideal practices. The article suggests that communication programs need to adopt a "social rationality" perspective based on nuanced understanding of community experience of TB. Suggestions are offered about how communication contributes to addressing challenges in TB control.

Persistent problems of access to appropriate, affordable TB services in rural China: experiences of different socio-economic groups

Background

Large-scale Tuberculosis (TB) control programmes in China have been hailed a success. Concerns remain, however, about whether the programme is reaching all sections of the population, particularly poorer groups within rural communities, and whether there are hidden costs. This study takes a household perspective to investigate receipt of appropriate care and affordability of services for different socio-economic groups with TB symptoms in rural China.

Methods

Secondary analysis of Chinese National Household Health Survey for 2003: 40,000 rural households containing 143,991 individuals, 2,308 identified as TB suspects. Outcomes: use of services and expenditure of TB suspects, by gender and socio-economic position, indicated by household income, education, material assets, and insurance status.

Results

37% of TB suspects did not seek any professional care, with low-income groups less likely to seek care than more affluent counterparts. Of those seeking care, only 35% received any of the recommended diagnostic tests. Of the 182 patients with a confirmed TB diagnosis, 104 (57%) received treatment at the recommended level, less likely if lacking health insurance or material assets. The burden of payment for services amounted to 45% of annual household income for the low-income group, 16% for the high-income group.

Conclusion

Access to appropriate, affordable TB services is still problematic in some rural areas of China, and receipt of care and affordability declines with declining socio-economic position. These findings highlight the current shortcomings of the national TB control programme in China and the formidable challenge it faces if it is to reach all sections of the population, including the poor with the highest burden of disease.

Directly observed therapy and tuberculosis: how can a systematic review of qualitative research contribute to improving services? A qualitative meta-synthesis

AIM

This paper reports the findings from a qualitative meta-synthesis concerning people with, or at risk of, tuberculosis, service providers and policymakers and their experiences and perceptions of tuberculosis and treatment.

BACKGROUND

Directly observed therapy is part of a package of interventions to improve tuberculosis treatment and adherence. A Cochrane systematic review of trials showed an absence of evidence for or against directly observed therapy compared with people treating themselves.

METHOD

Qualitative systematic review methods were used to search, screen, appraise and extract data thematic analysis was used to synthesize data from 1990 to 2002, and an update of literature to December 2005. Two questions were addressed: 'What does qualitative research tell us about the facilitators and barriers to accessing and complying with tuberculosis treatment?' and 'What does qualitative research tell us about the diverse results and effect sizes of the randomized controlled trials included in the Cochrane review?' Findings help explain the diverse trial results in a Cochrane systematic review of directly observed therapy and tuberculosis and consider implications for research, policy and practice.

FINDINGS

Five themes emerged from the 1990 to 2002 synthesis: socio-economic circumstances, material resources and individual agency; explanatory models and knowledge systems in relation to tuberculosis and its treatment; the experience of stigma and public discourses around tuberculosis; sanctions, incentives and support, and the social organization and social relationships of care. Two additional themes emerged from the 2005 update.

CONCLUSION

The qualitative meta-synthesis improved the relevance and scope of the Cochrane review of trials. The findings make a major contribution to the development of theory concerning global WHO-branded disease control and the practicality of local delivery to people.

Evaluation of the rpoB macroarray assay to detect rifampin resistance in Mycobacterium tuberculosis in Beijing, China

The aim of this study was to evaluate the modified rifampin oligonucleotide (RIFO) macroarray method to detect mutations in the hot-spot region of the rpoB gene, associated with rifampin (RIF) resistance in Mycobacterium tuberculosis. The study sample included 123 strains of M. tuberculosis isolated in the Beijing, China, area in 2002-2005, including 73 RIF-resistant and 40 pansusceptible strains. The genotypic assay successfully identified 91.8% of the RIF-resistant strains, whereas no mutations were found in RIF-susceptible strains. The most frequently detected rpoB mutations were in the codons 516, 526, and 531, together accounting for 74% of RIF-resistant strains. Spoligotyping subdivided all strains into 11 unique profiles and 3 profiles shared by 3, 4, and 103 strains, respectively. The 113 strains belonged to the Beijing family genotypes, defined by the specific spoligotype signature (absence of signals 1-34) and deletion of the RD105 region. The rpoB S531L (TCG-->TTG) mutation was found in 57.4% of the RIF-resistant strains of the Beijing genotype. A mutation in the rpoB hot-spot region was found in 51 of the 55 (92.7%) multidrug-resistant strains (i.e., resistant to at least RIF and isoniazid), thus demonstrating the added utility of the modified RIFO method to predict multidrug resistance. The RIFO method is relatively simple to perform and allows straightforward interpretation of results; consequently, it can be used in clinical diagnostic laboratories as a fast complement to phenotypic methods.

Multiple perspectives on diagnosis delay for tuberculosis from key stakeholders in poor rural China: case study in four provinces

This study aims to understand the contextual barriers to accessing timely TB diagnosis after first seeking care, especially among the poor and vulnerable in rural China. Both quantitative and qualitative methods were used to elicit the experiences and perspectives of TB patients and suspected TB patients, community residents, health providers and policy makers in poor, rural areas of four provinces. Between 30 and 60% of patients across the four provinces experienced a delay in receiving a diagnosis after first seeking care. Most patients had to visit health facilities more than once before diagnosis, with 17-30% patients making more than 6 visits. These delays and multiple visits mainly occurred because of the limited capacity of health providers to recognize TB, and financial disincentives to refer patients to TB dispensaries, due to the pressures of the cost recovery system. Poverty and socio-economic disadvantage amongst patients also influenced their capability to seek further care to obtain a reliable diagnosis. Qualitative data showed that women and the elderly patients were likely to experience more 'system' delay, and these findings were to some extent supported by the survey. The study concludes that 'system' delay is a serious problem, which is influenced by the financing mechanisms for both TB control and general health services as well as poverty and disadvantage amongst patients. This requires a comprehensive strategy to shorten 'system' delay in order to enable successful DOTS expansion, including developing appropriate financing mechanisms to improve general provider capacity and encourage referral, as well as measures to improve financial and social access to services for potential TB patients.
