Private doctors and tuberculosis control in India

Tapping private health sector for public health program? Findings of a novel intervention to tackle TB in Mumbai, India

BACKGROUND

India carries one-fourth of the global tuberculosis (TB) burden. Hence the country has drafted the ambitious National Strategic Plan to eliminate tuberculosis by 2025. To realise this goal, India's Revised National Tuberculosis Control Programme (RNTCP) and partners piloted a novel strategy to engage private-providers for tuberculosis care via a "Private-provider Interface Agency" (PPIA) in Mumbai and other locations.

INTERVENTION

The program mapped and engaged private-providers, chemists, and laboratories; facilitated TB notification via call centers and field staff; provided free tuberculosis diagnostic tests and anti-TB drugs using novel electronic vouchers; monitored quality of care; and supported patients to ensure anti-TB treatment adherence and completion. This report summarises the descriptive analysis of PPIA implementation data piloted in Mumbai from 2014 to 2017.

FINDINGS

The program mapped 8789 private doctors, 3438 chemists, and 985 laboratories. Of these, 3836 (44%) doctors, 285 (29%) laboratories, and 353 (10%) chemists were prioritized and engaged in the program. Over three and a half years, the program recorded 60,366 privately-notified tuberculosis patients, of which, 24,146 (40%) were microbiologically-confirmed, 5203 (9%) were rifampicin-resistant, and 4401 (7%) were paediatric TB patients. Mumbai's annual total TB case notification rate increased from a pre-program baseline of 272 per 100,000/year in 2013 to 416 per 100,000/year in 2017. Overall, 42,300 (78%) patients completed the TB treatment, and 4979 (9%) could not be evaluated.

INTERPRETATION

The PPIA program in Mumbai demonstrated that private-providers can be effectively engaged for TB control in urban India. This program has influenced national policy and has been adapted and funded for a country-wide scale up. The model may also be considered in conditions where private-provider engagement is needed to improve access and quality of care for any area of public health.

Map, know dynamics and act; a better way to engage private health sector in TB management. A report from Mumbai, India

BACKGROUND

India, world's leading Tuberculosis burden country envisions to End-TB by optimally engaging private-sector, in-spite of several unsuccessful attempts of optimal private sector engagement. Private Provider Interface Agency (PPIA), a new initiative for private-sector engagement, studied the private-sector networking and dynamics to understand the spread, typology of providers and facilities and their relations in TB case management, which was critical to design an intervention to engage private-sector. We report the observations of this exercise for a larger readership.

METHOD

ology: It is a descriptive analysis of mapping data (quantitative) and perceived factors influencing their engagement in the PPIA network (qualitative).

RESULTS

Of 7396 doctors, 2773 chemists and 747 laboratories mapped, 3776 (51%) doctors, 353 (13%) chemists and 255 (34%) laboratories were prioritized and engaged. While allopathic doctors highly varied between wards (mean ratio 48/100,000 population; range 13-131), non-allopathic doctors were more evenly distributed (mean ratio 58/100,000 population; range 36-83). The mean ratio between non-allopathic to allopathic doctors was 1.75. Return benefit, apprehension on continuity of funding and issues of working with the Government were top three concerns of private providers during engagement. Similarly, irrational business expectations, expectation of advance financing for surety and fear of getting branded as TB clinic were three top reasons for non-engagement.

CONCLUSION

A systematic study of dynamics of existing networking, typology and spread of private providers and using this information in establishing an ecosystem of referral network for TB control activities is crucial in an effort towards optimal engagement of private health providers. Understanding the factors influencing the network dynamics helped PPIA in effective engagement of private health providers in the project.

Private Practitioners' Perspectives on Their Involvement With the Tuberculosis Control Programme in a Southern Indian State

Background: Public and private health sectors both play a crucial role in the health systems of low- and middle-income countries (LMICs). The tuberculosis (TB) control strategy in India encourages the public sector to actively partner with private practitioners (PPs) to improve the quality of front line service delivery. However, ensuring effective and sustainable involvement of PPs constitutes a major challenge. This paper reports the findings from an empirical study focusing on the perspectives and experiences of PPs towards their involvement in TB control programme in India.

Methods: The study was carried out between November 2010 and December 2011 in a district of a Southern Indian State and utilised qualitative methodologies, combining observations and in-depth interviews with 21 PPs from different medical systems. The collected data was coded and analysed using thematic analysis.

Results: PPs perceived themselves to be crucial healthcare providers, with different roles within the public-private mix (PPM) TB policy. Despite this, PPs felt neglected and undervalued in the actual process of implementation of the PPM-TB policy. The entire process was considered to be government driven and their professional skills and knowledge of different medical systems remained unrecognised at the policy level, and weakened their relationship and bond with the policy and with the programme. PPs had contrasting perceptions about the different components of the TB programme that demonstrated the public sector’s dominance in the overall implementation of the DOTS strategy. Although PPs felt responsible for their TB patients, they found it difficult to perceive themselves as ‘partners with the TB programme.’

Conclusion: Public-private partnerships (PPPs) are increasingly utilized as a public health strategy to strengthen health systems. These policies will fail if the concerns of the PPs are neglected. To ensure their long-term involvement in the programme the abilities of PPs and the important perspectives from other Indian medical systems need to be recognised and supported.

Airborne infection control in India: Baseline assessment of health facilities

BACKGROUND

Tuberculosis transmission in health care settings represents a major public health problem. In 2010, national airborne infection control (AIC) guidelines were adopted in India. These guidelines included specific policies for TB prevention and control in health care settings. However, the feasibility and effectiveness of these guidelines have not been assessed in routine practice. This study aimed to conduct baseline assessments of AIC policies and practices within a convenience sample of 35 health care settings across 3 states in India and to assess the level of implementation at each facility after one year.

METHOD

A multi-agency, multidisciplinary panel of experts performed site visits using a standardized risk assessment tool to document current practices and review resource capacity. At the conclusion of each assessment, facility-specific recommendations were provided to improve AIC performance to align with national guidelines.

RESULT

Upon initial assessment, AIC systems were found to be poorly developed and implemented. Administrative controls were not commonly practiced and many departments needed renovation to achieve minimum environmental standards. One year after the baseline assessments, there were substantial improvements in both policy and practice.

CONCLUSION

A package of capacity building and systems development that followed national guidelines substantially improved implementation of AIC policies and practice.

Tuberculosis case notification by private practitioners in Pune, India: how well are we doing?

SETTING

Pimpri Chinchwad Municipal Corporation area, Pune, India.

OBJECTIVE

To assess the proportion of private practitioners (PPs) who notified tuberculosis (TB) patients during February-April 2013 and their contribution to the overall number notified, and to determine their perceived challenges in reporting TB cases.

DESIGN

Mixed-method study including an analysis of notification data, followed by in-depth interviews with PPs. Interviews were transcribed and inductive content analysis was performed to derive themes.

RESULTS

Of 831 PPs, 533 (64%) participated in case notification; of these 87 (16%) notified at least one TB case during the study period. In all, 138 TB cases were notified by PPs, accounting for 20% of the total TB cases notified. Emerging themes among perceived challenges and barriers were lack of complete knowledge about TB notification, fear of a breach of patient confidentiality, lack of a simplified operational mechanism of notification, and lack of trust and coordination with the government health system.

CONCLUSION

About two thirds of PPs participated in case notification and contributed significantly to the overall TB cases notified. India's national TB programme should focus on training PPs and targeted media communication campaigns, and establish alternative mechanisms for notification, such as the internet and mobile telephones, to overcome perceived barriers.

Organisational innovation and control practices: the case of public-private mix in tuberculosis control in India

Partnerships between public and private healthcare providers are often seen as an important way to improve health care in resource-constrained settings. Despite the reconfirmed policy support for including private providers into public tuberculosis control in India, the public-private mix (PPM) activities continue to face apprehension at local implementation sites. This article investigates the causes for those difficulties by examining PPM initiatives as cases of organisational innovation. It examines findings from semi-structured interviews, observations and document analyses in India around three different PPM models and the attempts of innovating and scaling up. The results reveal that in PPM initiatives underlying problem definitions and different control practices, including supervision, standardisation and culture, continue to clash and ultimately hinder the scaling up of PPM. Successful PPM initiatives require organisational control practices which are rooted in different professions to be bridged. This entails difficult balancing acts between innovation and control. The innovators handle those differently, based on their own ideas of the problem that PPM should address and their own control practices. We offer new perspectives on why collaboration is so difficult and show a possible way to mitigate the established apprehensions between professions in order to make organisational innovations, such as PPM, sustainable and scalable.

Are pulmonary opacities a marker of pulmonary tuberculosis?

BACKGROUND

On most occasions treatment of pulmonary tuberculosis is started by physicians based predominantly on radiological opacities. Since these opacities may not be suggestive of active pulmonary tuberculosis and most of these opacities may even remain unchanged after complete treatment, starting treatment solely on the basis of these opacities may lead to ambiguous end points of cure. In view of this, study of misdiagnosis of radiological opacities as active pulmonary tuberculosis by physicians was undertaken in one of the respiratory centers of Armed Forces hospitals.

METHODS

This was a prospective study of patients referred to our center for confirmation of active disease and institutional therapy. All patients who were diagnosed as pulmonary tuberculosis predominantly on radiological basis by physicians were evaluated for active pulmonary tuberculosis clinically, radiologically and microbiologically. Patients found to have inactive disease were followed for one year. At three monthly review, history, clinical examination, sputum AFB and chest radiographs were done.

RESULTS

There were 36 patients [all males, mean age: 36.9 years (range: 22-46 years)]. The most common initial presentation was of asymptomatic persons (33.3%) reporting for routine medical examination. The commonest radiological pattern was localized reticular opacities (52.8%)On follow up, only one patient was diagnosed to have pulmonary tuberculosis. The final diagnosis was consolidation in 6, bronchiectasis in 8, pulmonary tuberculosis in 1 and localized pulmonary fibrosis in 21 patients.

CONCLUSION

Diagnosing and treating tuberculosis predominantly on radiological basis is not appropriate and sputum microscopy and culture remains the cornerstone of diagnosing pulmonary tuberculosis.

The making of a public health problem: multi-drug resistant tuberculosis in India

This paper examines how actors construct the public problem of multi-drug resistant tuberculosis (MDR-TB) in India. MDR-TB has been framed by the World Health Organization as a pressing, global public health problem. The responses to MDR-TB are complicated as treatment takes longer and is more expensive than routine TB treatment. This is particularly problematic in countries, such as India, with high patient loads, a large and unregulated private sector, weak health systems and potentially high numbers of MDR-TB cases. This paper analyses how actors struggle for control over ownership, causal theories and political responsibility of the public problem of MDR-TB in India. It combines Gusfield's theory on the construction of public problems with insights from literature on the social construction of diseases and on medical social control. It highlights that there are flexible definitions of public problems, which are negotiated among actor groups and which shift over time. The Indian government has shifted its policy in recent years and acknowledged that MDR-TB needs to be dealt with within the TB programme. The study results reveal how the policy shift happened, why debates on the construction of MDR-TB as a public problem in India continue, and why actors with alternative theories than the government do not succeed in their lobbying efforts. Two main arguments are put forward. First, the construction of the public problem of MDR-TB in India is a social and political process. The need for representative data, international influence and politics define what is controllable. Second, the government seems to be anxious to control the definition of India's MDR-TB problem. This impedes an open, critical and transparent discussion on the definition of the public problem of MDR-TB, which is important in responding flexibly to emerging public health challenges.

Why are inaccurate tuberculosis serological tests widely used in the Indian private healthcare sector? A root-cause analysis

Serological tests for tuberculosis are inaccurate and WHO has recommended against their use. Although not used by the Revised National TB Control Programme (RNTCP), serodiagnostics are widely used in the private sector in India. A root-cause analysis was undertaken to determine why serological tests are so popular, and seven root causes were identified that can be grouped into three categories: technical/medical, economic, and regulatory. Technical/medical: RNTCP's current low budget does not allow scale-up of the newer, WHO-endorsed technologies. Thus, under the RNTCP, most patients have access to only smear microscopy, a test that is insensitive and underused in the private sector. Because there is no accurate, validated, point-of-care test for TB, serological tests meet a perceived need among doctors and patients. Economic: While imported molecular or liquid culture tests are too expensive, there are no affordable Indian versions on the market, leaving serological tests as the main alternative. Although serological tests are inaccurate, various players along the value chain profit from their use, and this sustains a market for these tests. Regulatory: TB tests are poorly regulated and a large number of serological kits are on the market. Private healthcare in general is poorly regulated, and doctors in the private sector are outside the scope of RNTCP and do not necessarily follow standard guidelines. A clear understanding of these realities should facilitate market-based strategies that can help replace serological tests with accurate, validated tools.

Role of Private Sector in Providing Tuberculosis Care: Evidence from a Population-based Survey in India

Background:

In India, a large segment of the population seeks health care services from individual or institutional private health-care providers for health care. We analyzed a nationally representative data to identify the role of private providers in delivering health care for patients with tuberculosis.

Materials and Methods:

The primary data source for the present analysis was the 60^th round of the National Sample Survey. Distribution frequencies were used to analyze the distribution of key sociodemographic variables and multiple logistic regression was used to analyze the association between these variables and healthcare seeking behavior.

Results:

A sample of 2203 respondents who had received ambulatory care for tuberculosis, and 4568 respondents who had received inpatient treatment were analyzed. About half of the respondents had attended private facilities for TB care. Sociodemographic variables such as paediatric age group, females, higher level of education, and economic groups were associated with attendance at private sector. Dissatisfaction with services in government facilities was cited as the main reason for preferring private facilities.

Conclusions:

Private providers play an important role in providing health care services to a large proportion of patients with tuberculosis. There is a need for innovative measures to increase participation of the private sector in the national TB control program and to improve the quality of services in government facilities.

A Qualitative Evaluation of the Information, Education, and Communication Component of the Tuberculosis Control Program in Delhi, India

Tuberculosis control programs have recognized and addressed those system components in which knowledge and behavior of the patient and the general population are key issues because they have a profound influence on the treatment-seeking behavior and completion of course of treatment. As a part of the Revised National Tuberculosis Control Program, the ongoing information, education, and communication (IEC) efforts in Delhi were further intensified in the form of a multipronged media campaign. The objectives of this study are to evaluate ( a) the impact of the campaign on awareness generation among the target audiences, ( b) their opinion for making the campaign more effective and suited to their needs, and ( c) perceptions of health personnel regarding the campaign. The study follows a descriptive cross-sectional design. The following qualitative methods were used: ( a) focus group discussions of patients and the general population, ( b) 3 key informant interviews of the health care personnel and a defaulter patient, and ( c) in-depth interviews of 20 DOTS (directly observed treatment, short course) providers. The study observed that ( a) different sociocultural segments of the population varied in terms of their observations of IEC messages, ( b) stigma associated with tuberculosis is widely prevalent despite having a campaign, and ( c) television was voted as the most effective IEC medium. IEC strategies should be tailor-made and suited to the needs of a particular subpopulation.

Community-based DOTS and family member DOTS for TB control in Nepal: costs and cost-effectiveness

Background

Two TB control strategies appropriate for South Asia (a community-based DOTS [CBD] strategy and a family-based DOTS [FBD] strategy) have been shown to be effective in Nepal in meeting the global target for the proportion of registered patients successfully treated. Here we estimate the costs and cost-effectiveness of the two strategies. This information is essential to allow meaningful comparisons between these and other strategies and will contribute to the small but growing body of knowledge on the costs and cost-effectiveness of different approaches to TB control.

Methods

In 2001–2, costs relating to TB diagnosis and care were collected for each strategy. Structured and semi-structured questionnaires were used to collect costs from health facility records and a sample of 10 patients in each of 10 districts, 3 using CBD and 2 using FBD. The data collected included costs to the health care system and social costs (including opportunity costs) incurred by patients and their supervisors. The cost-effectiveness of each strategy was estimated.

Results

Total recurrent costs per patient using the CBD and FBD strategies were US$76.2 and US$84.1 respectively. The social costs incurred by patients and their supervisors represent more than a third of total recurrent costs under each strategy (37% and 35% respectively). The CBD strategy was more cost-effective than the FBD strategy: recurrent costs per successful treatment were US$91.8 and US$102.2 respectively.

Discussion

Although the CBD strategy was more cost-effective than the FBD strategy in the study context, the estimates of cost-effectiveness were sensitive to relatively small changes in underlying costs and treatment outcomes. Even using these relatively patient-friendly approaches to DOTS, social costs can represent a significant financial burden for TB patients.

Barriers of mistrust: public and private health sectors' perceptions of each other in Madhya Pradesh, India

India has one of the most highly privatized health care systems in the world. The dominant private health sector functions alongside a traditional tiered public health sector. There has been an overall lack of collaboration between the two sectors despite international policy recommendations and local initiatives. It has been postulated that "conflicting perceptions" might contribute to the uncooperative attitude between the two sectors. But there has been little empirical exploration of the existing perceptions that the private and public health sectors have of each other. We explored these perceptions among key stakeholders (who influence the direction of health policy) in the public and private health sectors in the province of Madhya Pradesh, India. The barriers of mistrust, which hinder true dialogue, are complex, and have social, moral, and economic bases. They can be best addressed by necessary structural change before any significant long-term partnership between the two sectors is possible.

Costs of a successful public-private partnership for TB control in an urban setting in Nepal

Background

In South Asia a large number of patients seek treatment for TB from private practitioners (PPs), and there is increasing international interest in involving PPs in TB control. To evaluate the feasibility, effectiveness and costs of public-private partnerships (PPPs) for TB control, a PPP was developed in Lalitpur municipality, Nepal, where it is estimated that 50% of patients with TB are managed in the private sector. From the clinical perspective the PPP was shown to be effective. The aim of this paper is to assess and report on the costs involved in the PPP scheme.

Methods

The approach to costing took a comprehensive view, with inclusion of costs not only incurred by health facilities but also social costs borne by patients and their escorts. Semi-structured questionnaires and guided interviews were used to collect start-up and recurrent costs for the scheme.

Results

Overall costs for treating a TB patient under the PPP scheme averaged US$89.60. Start-up costs per patient represented 12% of the total budget. Half of recurrent costs were incurred by patients and their escorts, with institutional costs representing most of the rest. Female patients tended to spend more and patients referred from the private sector had the highest reported costs.

Conclusion

Treating TB patients in the PPP scheme had a low additional cost, while doubling the case notification rate and maintaining a high success rate. Costs incurred by patients and their escorts were the largest contributors to the overall total. This suggests a focus for follow-up studies and for cost-minimisation strategies.

Knowledge, attitudes, and practices of antiretroviral therapy among HIV-infected adults attending private and public clinics in India

India has approximately 5.2 million persons infected with HIV. Although antiretroviral therapy (ART) is being widely introduced in public clinics, many HIV-infected persons still seek care via the private sector. A cross-sectional survey was conducted in 2004 at six public and private sites to characterize the knowledge, attitudes, and practices (KAP) of ART among patients with HIV receiving care in India. Of 1667 persons surveyed, 609 (36%) had heard of ART and 19% of these persons reported that ART could cure HIV. Twenty-four percent reported that they were currently taking ART, with 18% of these patients not actually on ART according to their provider. Major barriers to taking ART were cost (33%), lack of knowledge of ART (41%), and deferral by physician (30%). More than half of all public and private patients had not heard of CD4 (57%) or viral load testing (80%), and even fewer had received these tests (32% and 11%, respectively). Private clinic attendees were almost 4 times more likely to be on ART (35% versus 9%, p < 0.0001), more likely to be male, have a higher education, be partnered, have a higher income, and have had a CD4 or viral load (p < 0.0001). Overall, low levels of ART knowledge and access were observed among HIV infected patients, with access to ART being particularly low among patients attending public clinics. In order to make widespread dissemination of ART effective in India, further educational and programmatic efforts are likely needed to optimize access, treatment awareness, and compliance among patients with HIV.

Nosocomial tuberculosis in India

India is well positioned to address the problem of nosocomial tuberculosis transmission.

Most high-income countries implement tuberculosis (TB) infection control programs to reduce the risk for nosocomial transmission. However, such control programs are not routinely implemented in India, the country that accounts for the largest number of TB cases in the world. Despite the high prevalence of TB in India and the expected high probability of nosocomial transmission, little is known about nosocomial and occupational TB there. The few available studies suggest that nosocomial TB may be a problem. We review the available data on this topic, describe factors that may facilitate nosocomial transmission in Indian healthcare settings, and consider the feasibility and applicability of various recommended infection control interventions in these settings. Finally, we outline the critical information needed to effectively address the problem of nosocomial transmission of TB in India.

Public-private partnerships for equity of access to care for tuberculosis and HIV/AIDS: lessons from Pune, India

The private medical sector is an important and rapidly growing source of health care in India. Private medical providers (PMP) are a diverse group, known to be poorly regulated by government policies and variable in the quality of services provided. Studies of their practices have documented inappropriate prescribing as well as violation of ethical guidelines on patient care. However, despite the critique that inequitable services characterise the private medical sector, PMPs remain important and preferred providers of primary care. This paper argues that their greater involvement in the public health framework is imperative to addressing the goal of health equity. Through a review of two research studies conducted in Pune, India, to examine the role of PMPs in tuberculosis (TB) and HIV/AIDS care, the themes of equity and access arising in private sector delivery of care for TB and HIV/AIDS are explored and the future policy directions for involving PMPs in public health programmes are highlighted. The paper concludes that public-private partnerships can enhance continuity of care for patients with TB and HIV/AIDS and argues that interventions to involve PMPs must be supported by appropriate research, along with political commitment and leadership from both public and private sectors.

Improving tuberculosis control through public-private collaboration in India: literature review

OBJECTIVE

To review the characteristics of public-private mix projects in India and their effect on case notification and treatment outcomes for tuberculosis.

DESIGN

Literature review.

DATA SOURCES

Review of surveillance records from Indian tuberculosis programme project, evaluation reports, and medical literature for public-private mix projects in India.

DATA EXTRACTION

Project characteristics, tuberculosis case notification of new patients with sputum smear results positive for acid fast bacilli, and treatment outcome.

DATA SYNTHESIS

Of 24 identified public-private mix projects, data were available from 14 (58%), involving private practitioners, corporations, and non-governmental organisations. In all reviewed projects, the public sector tuberculosis programme provided training and supervision of private providers. Among the five projects with available data on historical controls, case notification rates were higher after implementation of a public-private mix project. Among seven projects involving private practitioners, 2796 of 12 147 (23%) new patients positive for acid fast bacilli were attributed to private providers. Corporate based and non-governmental organisations served as the main source for tuberculosis programme services in seven project areas, detecting 9967 new patients positive for acid fast bacilli. In nine of 12 projects with data on treatment outcomes, private providers exceeded the programme target of 85% treatment success for new patients positive for acid fast bacilli.

CONCLUSIONS

Public-private mix activities were associated with increased case notification, while maintaining acceptable treatment outcomes. Collaborations between public and private providers of health care hold considerable potential to improve tuberculosis control in India.

Private providers and HIV testing in Pune, India: challenges and opportunities

We explored HIV testing practices of private medical providers in an urban Indian setting in Pune, western India. 215 private practitioners (PPs) and 36 persons-in-charge of private laboratories were interviewed in separate surveys. 77% of PPs had prescribed HIV tests and 94% of laboratories had performed HIV tests, or collected samples for HIV testing. Among those providers who had prescribed/performed tests, practices which violated national policy guidelines were found to be common. 55% of PPs and 94% of laboratories had not prescribed/performed confirmatory HIV tests, 82% of PPs had conducted routine HIV screening tests, 53% of PPs and 47% of laboratories had never counselled patients before testing, and 39% of laboratories reported breaching confidentiality of test results. PPs' knowledge about HIV tests was also inadequate, with 28% of PPs who had prescribed HIV tests being unable to name the tests they had advised. Prolific HIV testing in the private medical sector is accompanied by inappropriate practices and inadequate knowledge, reflecting deficiencies in the implementation of policy guidelines. The perspectives and needs of private providers, the major source of health care in India, need to be acknowledged. Supportive and regulatory mechanisms can be used to involve private providers in the delivery of better HIV testing services.

Malaria epidemiology in a rural area of the Mekong Delta: a prospective community-based study

Over the past 10 years, the Mekong Delta region in Vietnam has experienced fast socio-economic development with subsequent changes in malaria vectors ecology. We conducted a 2-year prospective community-based study in a coastal rural area in the southern Mekong Delta to re-assess the malaria epidemiological situation and the dynamics of transmission. The incidence rate of clinical malaria, established on 558 individuals followed for 23 months by active case detection and biannual cross-sectional surveys, was 2.6/100 person-years. Over the 2-year study period, the parasite rate and malaria seroprevalence (Plasmodium falciparum and P. vivax) decreased significantly from 2.4% to almost 0%. Passive case detection (PCD) of clinical cases and serological follow-up of newborns carried out in a larger population confirmed the low and decreasing trend of malaria transmission. The majority of fever cases were seen in the private sector and most were unnecessarily treated with antimalarials. Training and involvement of the private sector in detection of malaria cases would greatly improve the quality of health care and health information system.

What's said and what's done: the reality of sexually transmitted disease consultations

OBJECTIVE

Indirect data collection methods, or approaches which disturb usual practice, are generally used in health care evaluation. We have compared what doctors report at interview what is observed by an identified researcher with an unobtrusive measure of their usual practice.

DESIGN

Private practitioners who provide a service to sexually transmitted disease (STD) patients were interviewed regarding their usual case management. An identified researcher carried out structured observations of consultations between physicians and patients. Simulated clients then sought consultations, presenting a standardised history and symptom profile. Structured reporting of the history taking, examination, treatment and counselling aspects of these consultations was undertaken.

SUBJECTS

Eighteen private practitioners in Madras (now Chennai), India.

MAIN OUTCOME MEASURES

Comparisons between interviews, observations by identified researchers and the experiences of simulated clients were carried out.

RESULTS

Interviews with physicians and observations by identified researchers indicated more favourable practice than was seen during simulated client visits. These differences were substantial and would lead to a severe misrepresentation of the actual situation-and thus of intervention needs, if data from interviews or observations were relied upon.

CONCLUSIONS

The usual methods used in the evaluation of medical services and in carrying out medical audit may produce highly unreliable findings. STD services in the study area are failing to realise their potential of improving the sexual health of populations. The methodological and substantive findings of this study could be combined through the introduction of simulated client visits in the monitoring, improvement and licensing of STD (and perhaps other medical) services.

Shifting the focus of tuberculosis research in India

India has a long and distinguished tradition of research in the field of tuberculosis (TB). Pioneering studies from India demonstrated the efficacy and safety of domiciliary treatment, the necessity of direct observation of treatment, the feasibility of case detection through sputum smear microscopy in primary health care institutions, and the effectiveness of intermittent short-course chemotherapy. These findings laid the foundation of directly observed treatment, short course (DOTS), which has been adopted by nearly 150 countries worldwide. Today, India has the second-largest and the fastest-growing DOTS programme in the world. A strong component of programme evaluation and operational research is needed to sustain and expand DOTS in the context of a suboptimal primary health care system, a large and unregulated private health care system, and the dual threats of HIV and multidrug-resistant TB (MDR-TB). Therefore, the focus of TB research in India has shifted to the following operational research areas: evaluating models to involve the private health sector; assessing the role of incentives in increasing treatment compliance; examining gender differentials in the access to TB services; assessing risk factors for delay in diagnosis; evaluating diagnosis, treatment and prevention of TB among HIV-infected persons; monitoring MDR-TB; estimating cost-effectiveness of the DOTS programme; monitoring the quality of smear microscopy services; and measuring the current burden of TB. Research for developing newer diagnostic tools, drugs and vaccines remains a long-term priority. Greater networking is needed among national researchers, programme managers and policy-makers to translate the findings of research into policies and programmes to make TB control in India more effective and efficient.

Involving private practitioners and chest physicians in the control of tuberculosis

SETTING

Private practitioners including chest physicians are often an important obstacle to having a successful National Tuberculosis Programme (NTP) in low- and middle-income countries. This complicated situation has been present in most of the Latin American countries for many years.

OBJECTIVE

To design an intervention model to obtain collaboration and integration of specialist physicians in the actions of the NTP.

DESIGN

In 1998, the IUATLD designed a special interactive model of training courses, to be held in an important number of Latin American countries. This intensive (25h in 3 days) course was named "Importance of the role of chest physicians and their integration in NTP strategies". At the end of each course, the participants were invited to sign a series of agreements concerning controversial topics that had blocked collaboration in the past.

RESULTS

This course, adapted to the situation of the different countries, has been held 17 times in 9 different countries. So far, nearly 600 specialist physicians have been trained with this special model, and all of them have signed important agreements on future collaboration.

CONCLUSION

There has been an important improvement in integrating these specialist physicians into the actions of the NTPs. This intervention has contributed to a substantial improvement of tuberculosis control in the last 4 years in Latin America.

The relationship between disease control strategies and health system development: the case of TB

This paper focuses on the lack of dialogue and policy consonance between those taking the lead in health systems change and those developing specific disease control strategies. In the first part, the origins and characteristics of this situation are explained using, as an example, TB control. Attention is then paid to the development of disease control friendly health systems. Four aspects of policy development are analysed paying particular attention to TB control: analysis of policy context, mechanisms for collaboration between policy actors; agreement on decision-making processes; development of common aims and objectives. Although the focus is on TB control, the principles illustrated carry some relevance for other disease control programmes.

Controlling tuberculosis in India

BACKGROUND

Tuberculosis kills nearly 500,000 people in India each year. Until recently, less than half of patients with tuberculosis received an accurate diagnosis, and less than half of those received effective treatment.

METHODS

We analyzed the effects of new policies introduced in 1993 that have resulted in increased resources, improved laboratory-based diagnosis, direct observation of treatment, and the use of standardized antituberculosis regimens and reporting methods.

RESULTS

By September 2001, more than 200,000 health workers had been trained, and 436 million people (more than 40 percent of the entire population) had access to services. About 3.4 million patients had been evaluated for tuberculosis, and nearly 800,000 had received treatment, with a success rate greater than 80 percent. More than half of all those treated in the past 8 years were treated in the past 12 months.

CONCLUSIONS

India's tuberculosis-control program has been successful in improving access to care, the quality of diagnosis, and the likelihood of successful treatment. We estimate that the improved program has prevented 200,000 deaths, with indirect savings of more than $400 million--more than eight times the cost of implementation. It will be a substantial challenge to sustain and expand the program, given the country's level of economic development, limited primary health care system, and large and mostly unregulated private health care system, as well as the dual threats of the human immunodeficiency virus and multidrug-resistant tuberculosis.

Genetic diversity and evidence for acquired antimicrobial resistance in Mycobacterium tuberculosis at a large hospital in South India

OBJECTIVE

To assess genetic diversity and drug resistance of Mycobacterium tuberculosis isolates collected at Christian Medical College Hospital (CMCH), Vellore, India, between July 1995 and May 1996.

MATERIALS AND METHODS

Isolates were subjected to IS6110-based restriction fragment length polymorphism (RFLP) analysis and tested for resistance to isoniazid, rifampin, ethambutol, streptomycin, and pyrazinamide, and DNA from selected strains was sequenced in regions associated with drug resistance.

RESULTS

One hundred and one M. tuberculosis isolates were collected from 87 patients with pulmonary tuberculosis. Charts of 69 patients were reviewed for history of tuberculosis illness and treatment. DNA from 29 strains was sequenced in katG, rpoB, and gyrA, and sometimes pncA regions. Analysis by RFLP revealed a high degree of genetic diversity, with no identifiable clusters of infection. Of the strains tested, 51% were resistant to at least one antibiotic, and 43% were resistant to more than one drug. There was a high rate of resistance observed in patients whose charts indicated a history of improperly administered tuberculosis treatment, whereas little drug resistance was observed in patients never previously treated for tuberculosis. Sequencing of genes associated with drug resistance revealed several previously unreported mutations in resistant strains.

CONCLUSIONS

This analysis suggests that the cases of tuberculosis in the sample are largely reactivation of long-standing infections and that the drug resistance among patients in CMCH is largely acquired or secondary rather than attributable to the spread of drug-resistant strains.

Private practitioners and their role in the resurgence of malaria in Mumbai (Bombay) and Navi Mumbai (New Bombay), India: serving the affected or aiding an epidemic?

The increased emphasis on privatization of the health care sector in many developing countries by international financial institutions and national governments expects an expanding role for private health care practitioners in the management of major communicable diseases such as tuberculosis, malaria, acute respiratory infections (ARIs) and sexually transmitted diseases (STDs). Largely unexamined in the Indian context, however, is the socio-cultural context, the micro-level political environment in which private practitioners carry out their activities, and the quality of care they provide to their patients. Examining these aspects is significant given the impressive growth of the country's private health sector during the past decade. This paper reports the results of an ethnographic study carried out in Mumbai (Bombay) and Nav Mumbai (New Bombay), India on private general practitioners (GPs) and their role in the management of malaria at a time when these two neighboring cities were in the midst of the worst malaria epidemic in over 60 years. Described are the characteristics of a sample of 48 private practitioners from the two cities, and their clinics. This is followed by a discussion of the data gathered through untructured interviews with practitioners and patients, and complemented by observational data on doctor-patient encounters gathered at 16 clinics over a 9-month period. The findings of the study suggest that many practitioners in Mumbai and Navi Mumbai were poorly qualified and did not play a supportive role in the two cities' public health departments to bring the epidemic under control. The majority of the practitioners adopted diagnostic and treatment practices that were not consistent with the guidelines laid down by WHO and India's National Malaria Eradication Programme. Very few practitioners, especially those practicing in low-income areas, relied on a peripheral blood-smear test to make a diagnosis. Practitioners whose clientele was mostly the poor commonly resorted to giving one-day treatment to febrile patients that included injectable antimalarials and broad spectrum antibiotics. Such practitioners justified their mode of diagnosis and treatment by asserting that they were only responding to the demands placed on them by their patients who could not afford a blood-smear test or a full prescription. The paper argues that practitioners who acquiesced to patient demands were at once exacerbating the health problems of their patients and jeopardizing the prospects for the epidemic to be brought under control. Driven primarily by the need to retain the patronage of patients and maintain one's popularity in a highly competitive health arena, many providers practiced medicine that was unethical and dangerous. The paper concludes by discussing the ramifications of this study for malaria control in Mumbai and Navi Mumbai, and highlights a few salient health policy issues concerning the growth of the private health sector in India and its regulation.

Can I afford free treatment?: Perceived consequences of health care provider choices among people with tuberculosis in Ho Chi Minh City, Vietnam

Vietnam has a well-organised National TB Control Programme (NTP) with outstanding treatment results. Excellent prospect of cure is provided free of charge. Still, some people prefer to pay for their TB treatment themselves in private clinics. This is a potential threat to TB control since no notification of cases treated in the private sector occurs, and there is no control of the effectiveness of treatment provided in private clinics. Using a qualitative approach within a grounded theory framework, this study explores health-seeking behaviour among people with TB, applying a specific focus on reasons for choices of private versus pubic health care providers. The study identifies a number of characteristics of private TB care, which both seem attractive to patients and at the same time contrast sharply with the structure of the NTP strategy. These include flexible diagnostic procedures, no administrative procedures to establish eligibility for treatment, flexible choices of drug regimens, non-supervised treatment (no DOT), no tracing of defaulters in the household, no official registration of TB cases and thus less threat to personal integrity. A possibility to demand individualised service through the use of fee-for-service payments directly to physicians also seems attractive to many patients. A number of the components of the NTP strategy that have been put in place in order to secure optimal public health outcomes are lacking in the private sector. A dilemma for TB control is that this seems to be an important reason for why many people with TB opt for private providers where quality of care is virtually uncontrolled. The global threat of TB has led to calls for forceful measures to control TB. However, based on the findings in this study it is argued that the use of rigid approaches to TB control that do not encompass a strong component of responsiveness towards the needs of individuals may be counterproductive for public health.

Private health care

During the last decade there has been considerable international mobilisation around shrinking the role of States in health care. The World Bank reports that, in many low and middle-income countries, private sources of finance comprise the largest share of total national health expenditures. Private sector health care is ubiquitous, reaches throughout the population, preferred by the people and is significant from both economic as well as health perspective. Resources are limited, governments are weak, and a new approach is needed. This paper provides a broad overview and raises key issues with regard to private health care. The focus is on provision of health care by private medical providers. On the background of the world's common health problems and interventions available to tackle them, the place of private health care in the overall context is first discussed. The concept of privatisation within the various forms of health care systems is then explained. The paper then describes the genesis and key elements of rapidly enhancing role of the private sector in health care and points to the paucity of literature from low and middle-income countries. Common concerns about private health care are outlined. Two illustrative examples--tuberculosis, the top infectious killer among the poor and coronary heart disease, the top non-infectious killer among the rich--are presented to understand the current and possible role of private sector in provision of health care. Highlighting the need to distinguish between health care as a public good or a market commodity, the paper leaves it to the reader to draw conclusions.

Tuberculosis control in less developed countries: can culture explain the whole picture?

Healthcare practices, adherence to treatment, and organizational behaviour of healthcare workers are the main issues concerning tuberculosis (TB) control influenced by culture. A review of research findings published in the English language literature concerning these issues, and the way in which they are affected by cultural and structural factors is presented and discussed. These findings suggest that structural rather than cultural factors may be the main explanation for the questionable behaviour of healthcare workers and patients suffering from TB in less developed countries.

Assessment of worldwide tuberculosis control. WHO Global Surveillance and Monitoring Project

BACKGROUND

Because worldwide tuberculosis (TB) control had never been assessed, WHO set up a surveillance and monitoring project in 1995. The objectives were to assess the performance of national TB programmes; to assess the extent of implementation of the WHO strategy of TB control; and to attempt a comparison between regions that had adopted the WHO strategy and those that had not.

METHODS

In June, 1996, we sent data-collection forms requesting information on national TB programmes' control policies, 1995 case notifications, and 1994 treatment results to 216 countries, areas, and territories. We assessed the performance of national TB programmes by comparing case notifications with estimated incidence and by outcome of treatment in cohorts of patients. We also investigated worldwide treatment success and case detection among sputum-smear-positive patients.

FINDINGS

180 (83%) of the 216 countries, areas, and territories surveyed replied to WHO (98% of the worldwide population). In 1995, the WHO control strategy had been implemented in 75 countries, and in 39 of these implementation was countrywide. UP to 23% of the worldwide population lived in regions where the strategy was available. In 1995, 3 297 688 cases of TB (all types) were reported, of which 1161411 (35%) were sputum-smear positive. 54% of all reported cases in countries that used the WHO strategy were sputum-smear positive, compared with 30% in other countries. The worldwide case-detection rate of new sputum-smear-positive cases was 35%. 92% of cases registered for treatment in 1994 in regions that used WHO strategy were assessed for outcome and 76% were treated successfully, compared with 54% and 42%, respectively, in regions that had not implemented the WHO strategy. Among cases reported worldwide in 1994, the documented treatment-success rate was 43%.

INTERPRETATION

National TB programmes that have adopted the WHO TB control strategy achieve higher cure rates, but their impact on TB is modest on a worldwide scale. Wider continuous coverage with the WHO strategy is needed for effective worldwide TB control.

Front-line management of pulmonary tuberculosis: an analysis of tuberculosis and treatment practices in urban Sindh, Pakistan

SETTING

Karachi and Hyderabad, Pakistan.

OBJECTIVE

To describe the level and quality of tuberculosis (TB) case management by non-TB control program (TCP) physicians in urban Sindh, Pakistan.

DESIGN

We interviewed 152 adults with pulmonary TB confirmed by Karachi's TB control program regarding the initial management of their TB symptoms before entering the TCP. We also surveyed 65 general practitioners (GPs) attending continuing education seminars with a multiple choice test to assess their management of suspected pulmonary TB. We compared both results to guidelines from the World Health Organization (WHO) and the International Union Against Tuberculosis and Lung Disease (IUATLD).

RESULTS

Eighty percent (122/152) of patients first sought GPs. Only 14% of GPs performed any sputum test. At most, 17 (40%) of the 42 patients recalling their GP's treatment, received the recommended 4-drug regimen. However, 68% (45/65) of surveyed GPs chose correct treatment from a multiple choice format. But their initial laboratory investigations, follow-up, and treatment cessation criteria (9%, 9-31%, and 11% correct, respectively) demonstrated under-utilization of sputum tests and over-reliance on unhelpful tests.

CONCLUSIONS

GPs first saw most of these TCP patients, but their weak management likely hinders TB control. A partnership between TB control programs and GPs could improve case management and hasten TB control.

Survey of knowledge, attitudes and practices for tuberculosis among general practitioners

SETTING

Representative sample survey of knowledge, attitudes and practices (KAP) for tuberculosis among private general practitioners (GPs) in 1993 in Korea,

OBJECTIVE

To investigate the KAP of general practitioners on the prevention and treatment of tuberculosis.

DESIGN

Questionnaire surveys were performed for 923 private general practitioners through 29 health centres.

RESULTS

49% of GPs considered that the Korean tuberculosis situation is not serious. 54% were worried about infection from patients. 47% answered that BCG vaccination causes untoward reactions with no or limited effectiveness. 47% considered the National Tuberculosis Programme (NTP) unfavourably. Over 50% did not consider sputum examination essential in case finding/diagnosis, and 75% in monitoring of treatment response. For initial treatment of active tuberculosis, only 11% were prescribing the current Korean NTP's six-month standard regimen. 73% were giving currently non-recommendable regimens, and 16% unacceptably bad regimens. However, this situation could be improved, as 80% of GPs expressed the wish to acquire knowledge.

CONCLUSION

Many misunderstandings were found in the field of transmission, BCG vaccination and the performance of the NTP; sputum examinations were considerably neglected in case finding/diagnosis and treatment monitoring. As for treatment, 89% were giving either non-recommendable regimens or bad regimens.
