Impact of HIV scale-up on health workforce dynamics: opportunities for rethinking traditional roles and concepts
IAS pre-conference meeting: Accelerating the Impact of HIV Programming on Health Systems Strengthening 17/18 July 2009
Uta Lehmann, School of Public Health, University of the Western Cape
Outline
Key factors impacting on the health workforce
Increasing demand through sicker populations
Fewer professionals
Strong civil society response
New mid-level and community-based cadres
Health sector reform
Policy responses
Increased production
Task-shifting and renewed interest in community participation and the use of lay personnel (often post hoc)
Increased interest in the softer issues of HRH: staff motivation, leadership, power, etc.
Policy and evidence gaps

Example of delivery gap in South Africa:
2. Fewer professionals:
Staff numbers in public sector (which serves around 85% of population) in South Africa:
10,000 doctors (30% of those registered)
45,000 professional nurses (42% of those registered)
21,000 enrolled nurses (52% of those registered)
Around 40,000 lay health workers

3. Strong civil society response
CBOs, faith-based organisation, NGOs involved in various aspects of advocacy, treatment, care, etc.
So, less professional personnel available, but large numbers of para-professional and lay personnel: Provincial health departments in South Africa employ close to 40,000 CHWs through 1,636 NPOs. In comparison, in 2008, the public health sector employed 48,000 professional nurses

5. Health sector reform:
Particularly in South Africa these developments occurred in conjunction with health sector reform initiatives which have lead to an unprecedented deterioration of relationships and trust in the services.

‘It looks as if the work we do is not enough and the management does not appreciate whatever we do and thus the nurses become less motivated…. I think due to frustration of what the nurses go through with their work, they express their anger by becoming nasty to the patients…’

So what have been key policy responses?
Increased production Task shifting and renewed interest in community participation and the use of lay personnel (often post hoc ) Beginning, but as yet fairly unsystematic interest in the softer issues of HRH: staff motivation, leadership, power, etc.
Increased production: Yes, but …
WHO estimates that the WHO African Region has a shortfall of 817 992 doctors, nurses and midwives => need to more than double the workforce among these professional categories. It takes six years to train a new doctor, three or four to train a nurse and four to train a midwife. Moreover, current training facilities are insufficient to meet the need fast enough.
The medical schools in continental Africa currently turn out only 5,100 graduates per year, and many of these newly qualified doctors migrate to jobs abroad.
Task shifting and use of alternative cadres:
Reviews of evidence consistently show that delegation of tasks, whether from doctors to non-physician clinicians, including nurses, from nurses to nursing assistants or aides or to non-professional or lay health workers and patients can lead to improvements in access, coverage and quality of health services at comparable or lower cost than traditional delivery models.
Well documented eg. In Mozambique, Ethiopia, Malawi, Uganda, Zambia, Brazil, India
Example Uganda
In Uganda, task shifting is already the basis for providing antiretroviral therapy. With only one doctor for every 22 000 patients and an overall health worker deficit of up to 80%, Uganda’s nurses are now undertaking a range of tasks that were formerly the responsibility of doctors. These include: managing people living with HIV who have opportunistic infections; diagnosing tuberculosis sputum positive; prescribing medicine to prevent other infections; determining the clinical stage of people living with HIV; deciding whether people living with HIV have medical eligibility for antiretroviral therapy; and managing people on antiretroviral therapy who have minor side effects such as nausea.
In turn, tasks that were formerly the responsibility of nurses have been shifted to community health workers, who have training but not professional qualifications. These tasks include: HIV testing; counselling and education on antiretroviral therapy; monitoring and supporting adherence to antiretroviral therapy; filling in registers; triage; clinical follow-up; taking weight and vital signs; and explaining how to store antiretroviral drugs.

Policy gap I
Despite the evidence – and the insight that success of these programmes requires long-term planning and resourcing CHW programmes generally remain on the periphery of health systems and are considered an emergency measure Are not sustainably funded; Simultaneously draw very high expectations and very low investment.
=> NEED TO ACT ON EVIDENCE
Evidence gap:
Our understanding of how CHWs interact with and impact on households and communities is limited as is our insight into what models of delivery work best.
Policy gap II:
Systematic reconfiguration of health worker teams at PHC and community levels (What services are rendered? What skills are needed for these services? Who can provide these services? What gets shifted?) Reconfiguring specifically the role of professional nurses in this context (Clinicians and/or carers; what about medical assistants? What have nurses taken on already? What can they take on?).
Policy and evidence gap III:
Systematic engagement with and addressing of “soft” issues, i.e. impact of eg. leadership, power, motivation, organisational and professional cultures on health systems functioning, policy development and implementation, ultimately health outcomes.
This requires health systems research to resolutely step beyond traditional boundaries and start engaging systematically with social science methodology; eg. Social theory, ethnography, policy analysis.
How do we develop evidence and policy? Where and how does learning take place? Importantly by: Building local capacity for innovative practice.
Strengthening health service and civil society capacity to generate, process and use evidence for practice and advocacy (knowledge translation).
Encouraging collaboration between diverse stakeholders.
Supporting research which encourages organisational innovation and better understanding power dimensions of organisational practice.
To end, two voices from PHC services which make this point:
… until it becomes an environment in which you can actually learn from your mistakes, where you support each other more, you won’t get something like this being accepted because this is actually about saying where are we doing well but it’s also saying, and unfortunately the most is where are we not doing well….
… this needs to be an item on the agenda, this is one organisational culture we are trying to develop because unless you actually are being deliberate about it you will continue with the same.
