BackgroundUganda has a severe health worker shortage and a high demand for health care services. This study aimed to assess the policy and programmatic implications of task shifting in Uganda.MethodsThis was a qualitative, descriptive study through 34 key informant interviews and eight (8) focus group discussions, with participants from various levels of the health system.ResultsPolicy makers understood task shifting, but front-line health workers had misconceptions on the meaning and intention(s) of task shifting. Examples were cited of task shifting within the Ugandan health system, some formalized (e.g. psychiatric clinical officers), and some informal ones (e.g. nurses inserting IV lines and initiating treatment). There was apparently high acceptance of task shifting in HIV/AIDS service delivery, with involvement of community health workers (CHW) and PLWHA in care and support of AIDS patients.There was no written policy or guidelines on task shifting, but the policy environment was reportedly conducive with plans to develop a policy and guidelines on task shifting.Factors favouring task shifting included successful examples of task shifting, proper referral channels, the need for services, scarcity of skills and focused initiatives such as home based management of fever. Barriers to task shifting included reluctance to change, protection of professional turf, professional boundaries and regulations, heavy workload and high disease burden, poor planning, lack of a task shifting champion, lack of guidelines, the name task shifting itself, and unemployed health professionals.There were both positive and negative views on task shifting: the positive ones cast task shifting as one of the solutions to the dual problem of lack of skills and high demand for service, and as something that is already happening; while negative ones saw it as a quick fix intended for the poor, a threat to quality care and likely to compromise the health system.ConclusionThere were widespread examples of task in Uganda, and task shifting was mainly attributed to HRH shortages coupled with the high demand for healthcare services. There is need for clear policy and guidelines to regulate task shifting and protect those who undertake delegated tasks.

BackgroundThis paper arises from a four-country study that sought to better understand the drivers of skilled health worker migration, its consequences, and the strategies countries have employed to mitigate negative impacts. The four countries—Jamaica, India, the Philippines, and South Africa—have historically been “sources” of skilled health workers (SHWs) migrating to other countries. This paper presents the findings from South Africa.MethodsThe study began with a scoping review of the literature on health worker migration from South Africa, followed by empirical data collected from skilled health workers and stakeholders. Surveys were conducted with physicians, nurses, pharmacists, and dentists. Interviews were conducted with key informants representing educators, regulators, national and local governments, private and public sector health facilities, recruitment agencies, and professional associations and councils. Survey data were analyzed using descriptive statistics and regression models. Interview data were analyzed thematically.ResultsThere has been an overall decrease in out-migration of skilled health workers from South Africa since the early 2000s largely attributed to a reduced need for foreign-trained skilled health workers in destination countries, limitations on recruitment, and tighter migration rules. Low levels of worker satisfaction persist, although the Occupation Specific Dispensation (OSD) policy (2007), which increased wages for health workers, has been described as critical in retaining South African nurses. Return migration was reportedly a common occurrence. The consequences attributed to SHW migration are mixed, but shortages appear to have declined. Most promising initiatives are those designed to reinforce the South African health system and undertaken within South Africa itself.ConclusionsIn the near past, South Africa’s health worker shortages as a result of emigration were viewed as significant and harmful. Currently, domestic policies to improve health care and the health workforce including innovations such as new skilled health worker cadres and OSD policies appear to have served to decrease SHW shortages to some extent. Decreased global demand for health workers and indications that South African SHWs primarily use migratory routes for professional development suggest that health worker shortages as a result of permanent migration no longer pertains to South Africa.

Haruan, Channa striatus, is a snakehead fish consumed in many parts of the southeast Asian region. It is believed to promote wound healing, as well as reduce post-operative pain. In an attempt to establish the scientific basis for the alleged pain-relieving benefits of this fish, we studied the antinociceptive effects of whole fillet and mucus extracts from haruan in the mouse using the abdominal constriction and tail flick tests. In the abdominal constriction test, the 30 min fillet extract exhibited concentration-dependent inhibition of the writhing response in the 10-50% concentration range, with 20% as the IC50 value. This activity was not dependent on the duration of extraction, with no significant differences among the extracts obtained at durations of 10, 20, 30, 60, 90 and 120 min (range between 45-54% inhibition at 20% concentration). The mucus extract also showed concentration-dependent inhibition of the abdominal constriction response-at the highest concentration used the average inhibition was 68.9%, while IC50 value was 25%. Neither the fillet extract (30 min, 20%) nor the mucus extract (25%) had any demonstrable effect on the tail flick latency on their own, but significantly enhanced the antinociceptive activity of morphine in this assay. Similarly, low concentrations of the mucus and fillet extract enhanced the effects of morphine in the abdominal constriction test. Collectively, these results suggest a scientific basis for the folklore practice of eating haruan fish in the post-operative period for pain relief: Haruan extracts have antinociceptive activity and enhance the activity of other antinociceptive agents.

UNITRA medical students are optimistic about the future. The majority intend to stay in South Africa and work in the public sector, and most of them wish to pursue clinical specialties.

1 The possible involvement of nitric oxide (NO) in the induction and expression of morphine tolerance and dependence was studied in mice. A two-day repeated injection regimen was used to induce morphine tolerance and dependence. Tolerance was assessed by the tail flick test and physical dependence by naloxone challenge, on the third day. 2 Two days pretreatment with L-arginine (20 mg kg-', twice daily) or D-N0-nitro arginine methyl ester (D-NAME, 20 mg kg-', twice daily) alone had no effect on subsequent morphine antinociception. L-NG_ monomethyl arginine (L-NMMA, 10 mg kg-', twice daily) for two days led to a slight increase (not statistically significant) in morphine antinociception; while L-NG-nitro arginine methyl ester (L-NAME, 10 mg kg-', twice daily) for two days led to attenuation of morphine analgesia. None of the animals treated with these drugs alone showed signs characteristic of the opioid withdrawal syndrome upon naloxone challenge. 3

Background: South Africa has a high tuberculosis burden, and Limpopo Province experienced higher than national average TB mortality rates between 1997 and 2008. Objective: To establish factors associated with TB mortality in Limpopo Province in 2008.

Gene expression of proinflammatory cytokines in alveolar macrophages increased significantly over time. The increases were greater during isoflurane than propofol anesthesia, suggesting that inflammatory responses at transcriptional levels in alveolar macrophages are modulated by the type and duration of anesthesia.

BackgroundDespite a global recognition from all stakeholders of the gravity and urgency of health worker shortage in Africa, little progress has been achieved to improve health worker coverage in many of the African human resources for health (HRH) crisis countries. The problem consists in how policy is made, how leaders are accountable, how the World Health Organization (WHO) and foreign donors encourage (or distort) health policy, and how development objectives are prioritized in these countries.MethodsThis paper uses political economy analysis, which stems from a recognition that the solution to the shortage of health workers across Africa involves more than a technical response. A number of institutional arrangements dampen investments in HRH, including a mismatch between officials’ tenure in office and program results, the vertical nature of health programming, the modalities of Overseas Development Assistance (ODA) in health, the structures of the global health community, and the weak capacity in HRH units within Ministries of Health. A major change in policymaking would only occur with a disruption to the political or institutional order.Results/conclusionsThe case study of Ethiopia, who has increased its health workforce dramatically over the last 20 years, disrupted previous institutional arrangements through the power of ideas—HRH as a key intermediate development objective. The framing of HRH created the rationale for the political commitment to HRH investment. Ethiopia demonstrates that political will coupled with strong state capacity and adequate resource mobilization can overcome the institutional hurdles above. Donors will follow the lead of a country with long-term political commitment to HRH, as they did in Ethiopia.
