Laboratory administrative structures and enabling environment for TB diagnosis in public health settings (some reflections)


Public Health administration lays generally within the purview respective country government and with Ministry of Health. Within Ministry of health, public health diseases form a separate ‘unit’, ‘division’, 'department' or ‘directorate’ based on the staffing, reporting lines, level of management and importance of disease burden. Tuberculosis is public health problem categorized under the communicable diseases group along with HIV/AIDS and Malaria. In Africa, several of the administrative structures were established in colonial era, and does not reflect present realities. Although post-colonial era pandemic- such as HIV/AIDS-grow into new administrative structures, the old health structures often readjust to the new realities. In several African countries, public health laboratory services are a separate directorate, or unit within the ministry of health. Due to emergency of HIV/AIDS, in general, the administrative structure of it has direct reporting linkages with highest decision making authority in the countries, often above the ministry of health.  In this blog let’s review prevalent structure for delivery of public laboratory services (focused on TB) in Africa. An enabling environment in faster implementation of policy changes needed with changing public health policies and WHO/ International health policy requirements depends on understanding strengths and weakness of health administrative structures, particularly, laboratory and treatment linkages. 

Type 1: Laboratory services and public health services are two separate directorates under ministry of Health. National TB program is under the directorate of public health diseases, although national reference laboratory (if building existed historically) is partly ‘owned’ by NTP- and staffed by the directorate of Laboratory services. Teaching universities/academic institutes with lots of students and interns waiting to do their degrees and projects would like to be associated with public health labs where samples are aplenty.  This makes a university teacher/ medical microbiology in general, ideally suited to lead the National TB lab, ex-officio.  The teacher draws salary from university, and research drive/large scale samples (ethically) from the public health labs. Funding is partly from research studies (projects), government (for utilities), and National TB Program (through donors). (Uganda model)
Type 2: Laboratory services and disease control/ Public Health are two separate directorates/ departments under the MOH. However, TB reference Lab falls within the purview of general laboratory services and reports to directorate of lab services. The principle technologist or in-charge of TB lab does double reporting, in practise. The academic/teaching institutes are weak or non-existing. Service provision occupies most of the time, and no time left out for conducting any operational studies. Funding is both from Lab services and also from disease control divisions. (Lesotho, Swaziland, Kenya, Eritrea, Botswana etc., majority of Southern and East African countries come under this model)  
Type 3: Laboratory services are under a parastatal body. Government-owned commercial entity providing laboratory services at a cost to the ministry of health. All disease control programs buy the lab services from this body. To exist and survive, this system is government’s baby and has no notable competition from Private labs in the country. To retain the competitive advantage, the parastatal body also offers services to the private bodies and individuals. A board of members duly appointed by the Ministry of health run the management. It works for accountability, as per test costs provide operational costs. Insurance (medical aid) organisations also support this model. Namibia is exclusive member of this model. To be successful in this model, the price for per-test should be determined proper costing such that not be prohibitive while obtaining the tests. South Africa also has similar model. Although the management of public health lab services is independent of government interference, on day-to-day basis, the final financial issues are fully managed by MOH and private institutions do not get availed the lab services without referral.  

Key issues for efficiency in all these models are funding source, linkages with disease control programs, sustainability of the funding, accountability and quality management of resources. No model seems to fit ideal- although autonomously (parastatal) run lab services with commitment to public health laboratory functions and direct linkages with disease control programs seems a better system.
