Under the Microscope
Building up capacity in South Africa’s public health sector
Agreat deal of hope is hinging on the South African government’s National Health Insurance (NHI) scheme. Designed to address growing inequalities between public and private provision of healthcare, the premise behind NHI has been widely welcomed by industry stakeholders, be they medical organisations or consumers who stand to benefit in a potentially lifechanging way.
It is a cause for optimism for the likes of Dr Karmani Chetty, seasoned doctor and Acting CEO of South Africa’s National Health Laboratory Service (NHLS).
“The biggest challenges facing the country’s healthcare market at the moment are an under-resourced public health sector, lack of skilled and competent human resources, poor quality of services, and rising costs,” she explains.
“The South African health system is inequitable with the privileged few having disproportionate access to health services. The public sector is under-resourced relative to the size of the population that it serves and the burden of disease, and has disproportionately less human resources than the private sector, yet
has to manage significantly higher patient numbers.
“However, NHI will ensure that everyone has access to appropriate efficient and quality health services. It is intended to bring about reform that will improve service provision and will promote equity and efficiency, so as to ensure that all South Africans can use affordable, quality healthcare services regardless of their socioeconomic status.
“I am therefore very optimistic that the NHI will open up access to medical services.”
A nationwide mandate
Dr Chetty is a medical veteran. Holding a specialist degree in public health, she has been involved with the industry for more than three decades, with 20-plus years of this time being spent in senior management positions.
Working in both national and provincial departments of health in South Africa, Dr Chetty was aware of the NHLS and the challenges facing the organisation, something she is passionate about addressing in her role as Acting CEO.
The group is a national public entity established by law in 2000 to provide quality, affordable and sustainable health laboratory and related public health services to all public healthcare providers, other government institutions and any private healthcare provider in need of service.
It is also mandated to support health research and provide training for health science education across the country.
The enterprise consists of two major institutes. The National Institute for Communicable Disease is responsible for surveillance and monitoring of communicable diseases, while the National Institute for Occupational Health investigates occupational diseases and provides a range of related services.
“Further, the NHLS trains pathologists, scientists, medical technologists and technicians in conjunction with university medical schools and universities of technology,” states Dr Chetty.
“It is also the largest diagnostic pathology service in South Africa, with a network of approximately 226 pathology laboratories and providing approximately 1,500 different tests in all pathology disciplines.”
A smaller, but still important niche of the group is its South African Vaccine Producers (SAVP) subsidiary.
Situated in Sandringham, Johannesburg, it is tasked with the manufacturing of antivenom to treat snake, scorpion and spider envenomation, and is the only producer of such treatments in the whole of South Africa.
Africa is home to some of the deadliest snakes in the world, and SAVP produces antivenoms to treat bites from Black Mamba, Green Mamba, Jameson’s Mamba, Cape Cobra, Snouted Cobra, (Egyptian Cobra), Forest Cobra, Gaboon Adder, Mozambique Spitting Cobra, Puff Adder and Rinkhals.
All of this work is underpinned by a vision and set of values that make the NHLS what it is today.
Dr Chetty continues: “Our vision is to be an ‘Efficient Patient Centred
Further, the NHLS trains pathologists, scientists, medical technologists and technicians in conjunction with university medical schools and universities of technology”
Services and Global Centre of Excellence for Innovative Laboratory Medicine’. The organisation has identified several key values as the principles that will govern behaviour for all employees within it.”
There are six such values that Dr Chetty and the NHLS swear by, the first being care, to ensure the wellbeing of patients, the environment and society.
Second is unity of purpose, all working towards a common goal, while service excellence is another key pillar of this value proposition.
Transformation and innovation are values which make sure the NHLS is a forward-thinking organisation, with all of the aforementioned principles underlined by integrity, ethics and responsibility.
BSL-4 – a continental flagbearer
A fundamental and unique part of the NHLS laboratory network is its BSL-4 lab based at the National Institute for Communicable Diseases (NICD), a body which was set up in 2002.
The specialist communicable disease arm was established under the NHLS and came into being through the merging of the National Institute for Virology, the Virology Laboratories and Public Health Microbiology Laboratories of the South African Institute for Medical Research.
The centre deals with deadly viruses, a major killer in South
Africa behind the likes of HIV and tuberculosis, diseases which form the basis of two separate NHLS priority programmes.
Last year Statistics South Africa released data from 2016 on the leading causes of death in the country, stating that human immunodeficiency virus, influenza and pneumonia, and other viral diseases accounted for more than 12.5 percent of all fatalities.
Another deadly virus, Ebola, ravaged West Africa in 2014-2016 in what was the largest and most complex outbreak since it was first discovered in 1976.
It was this initial discovery in the 1970s, along with the sudden emergence of Lassa and Marburg and occurrence of laboratory infections in Europe and America that prompted the development of maximum-security laboratories (biosafety level four – BSL-4).
“The South African Department of Health decided to construct a BSL-4 laboratory at what is now known as the NICD in 1976,” recalls Dr Chetty. “Construction was completed in 1979, and in 1980 the facility started to operate for the purpose of providing a diagnostic and investigatory service for viral haemorrhagic fevers in southern Africa.
