چکیده
The Challenge of Managing NonCommunicable Diseases in SubSaharan Africa In sub-Saharan Africa (SSA), communicable diseases, particularly HIV/AIDS, tuberculosis (TB), and malaria, are still responsible for the greatest burden of morbidity and mortality [1]. However, noncommunicable diseases (NCDs) are becoming a significant burden [1]. The Global Burden of Disease Study, conducted in 2001, showed that 20% of deaths in SSA were due to NCDs [2], and this burden is predicted to rise to 40% by 2020 [3]. Obesity, hypertension, diabetes mellitus, cardiovascular disease, asthma, chronic obstructive pulmonary disease, epilepsy, and mental illness are some of the important, chronic NCDs that pose significant challenges in terms of management and follow-up. How are NCDs currently managed in the routine health care settings of African countries? In brief, badly. Anecdotal reviews point to poorly managed health care systems with frequent stock interruptions of essential drugs [4–6]. Untreated hypertension is blamed for high rates of stroke morbidity and mortality in urban and rural Tanzania [7] and rural South Africa [8,9]. Only a small proportion of patients with epilepsy receive drug treatment at any one time, mainly due to poor health care delivery systems and unavailability of drugs [10]. Even in specialist centres, asthma patients are given sub-standard care [11] and have poor access to essential medications [12]. There is a growing burden of diabetes mellitus and its associated complications, and many patients with type 1 diabetes mellitus have extremely short life expectancies [13]. Some of us know from personal experience of running routine diabetes and hypertension clinics in African hospitals that there are no formalised systems of recording how many patients have been diagnosed and started on therapy, how many are retained on therapy, or what proportion have died or developed complications. We treat patients with whatever drugs are available, and consider that our mission is accomplished. In summary, unstructured and unmonitored clinical care and little information about morbidity or mortality from NCDs are mostly the norm in sub-Saharan Africa [14]. How do we begin to rectify this unsatisfactory situation? A possible solution arises out of the existing “DOTS” framework for control of TB.

متن کاملNon-physician Clinicians – A Gain for Physicians’ Working in Sub-Saharan Africa; Comment on “Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians”
The changing demands on the health sectors in low- and middle-income countries especially sub-Saharan African countries continue to challenge efforts to address critical shortages of the health workforce. Addressing these challenges have led to the evolution of “non-physician clinicians” (NPCs), that assume some physician roles and thus mitigate the continuing shortage of doctors in these count...

Health workforce shortages in Sub-Saharan Africa are widely recognized, particularly of physicians, leading the training and deployment of Non-physician clinicians (NPCs). The paper by Eyal et al provides interesting and legitimate viewpoints on evolving role of physicians in context of decisive increase of NPCss in Sub-Saharan Africa. Certainly, in short or mid-term, NPCs will continue to be a...
متن کاملA New Generation of Physicians in Sub-Saharan Africa?; Comment on “Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians”
This commentary follows up on an editorial by Eyal and colleagues in which these authors discuss the implications of the emergence of non-physician clinicians (NPCs) on the health labour market for the education of medical doctors. We generally agree with those authors and we want to stress the importance of clarifying the terminology to describe these practitioners and of defining more formall...

Recent proposals for re-defining the roles Africa’s health workforce are a continuation of the discussions that have been held since colonial times. The proposals have centred on basing the continent’s healthcare delivery on non-physician clinicians (NPCs) who can be quickly trained and widely distributed to treat majority of the common diseases. Whilst seemingly logical, the success of these p...
