The central role of communities in the response to tuberculosis has long been recognised by policy makers1 and patients2 as an ethical and pragmatic imperative for successful programmes. In many countries, especially where tuberculosis is fuelled by HIV, government health-care providers have been outstripped of their ability to cope with the levels of service delivery needed to meet targets.3 Therefore advance on the implementation of tuberculosis programmes needs broader community engagement.
Experience has shown the immense added value of such engagement. For example, in Lesotho, lay health workers who give home-based services to patients are a cornerstone of the country's drug-resistant tuberculosis programme.4 Community engagement not only increases the strength and scope of implementation efforts, but also plays an important part in the development of policies and programmes,5 because a truly patient-centred approach to tuberculosis6 needs to be shaped by the patient.
However, the prevailing dearth of information about community participation in national tuberculosis programmes7 suggests that the patient-centred approach, although embraced in rhetoric, has been neglected in practice. Health-care workers continue to be the main providers of directly-recorded treatment, as is the case in 86% of countries reporting to WHO,7 despite the barriers to access and adherence that clinic-centred models of care can create. In many countries, patients' behaviours are subjected to punitive regulation under environmental and public health laws, which endorse measures such as immigration restrictions and mandatory detention in the response to tuberculosis.
These examples are far from being patient-centred and from promoting community participation, despite the indisputable and substantial benefit that this participation would bring to tuberculosis programmes. Instead, they point to the persistence of the historically coercive model of tuberculosis control,8 a model that inherently disenfranchises patients and can lead to violation of rights, alienation of patients, and reinforcement of stigma, thus undermining the improved outcomes that the model ostensibly aims to achieve.
