Dynamiques urbaines et santé des enfants en Afrique subsaharienne : Perspectives théoriques

Les enjeux de développement en rapport avec la santé urbaine des enfants en Afrique sub-saharienne deviennent d’autant plus importants qu’on a eu à observer dans certaines villes un paradoxe sanitaire se traduisant par une mortalité relativement plus élevée que celle du milieu rural. En outre, concilier la croissance rapide des villes africaines avec l’objectif d’un environnement sanitaire adéquat et adapté à l’ampleur et à la diversité des besoins relève du défi. Cet article propose un état des lieux critique de la littérature sur la santé urbaine, à travers une synthèse de 82 travaux scientifiques portant sur les relations entre dynamiques urbaines et sanitaires. L’étude accorde un regard particulier à la santé des enfants en Afrique subsaharienne francophone. Cette synthèse met en évidence les points de convergences et de divergences de santé urbaine, et aborde aussi, sous un angle critique, les aspects méthodologiques. Elle met en évidence une pluralité de situations sanitaires urbaines, ainsi que la complexité des mécanismes explicatifs des relations entre dynamique urbaine et santé des populations.

Deficiencies in education and experience in the management of acute kidney injury among Malawian healthcare workers

Background Acute kidney injury (AKI) is a common but under-recognised disease process, which carries a high risk of mortality or chronic complications, such as chronic kidney disease and other organ dysfunction. Management of AKI, however, is suboptimal, both in developed settings and in Malawi. This is partly because of deficiencies in AKI education and training. Aim To establish current levels of AKI education in a range of healthcare workers in Malawi. Methods An AKI symposium was held in Blantyre in March 2015. Delegates were asked to complete a survey at the start of the symposium to assess their clinical experience and education in the management of AKI. Results From 100 delegates, 89 nurses, clinical officers, and physicians, originating from 11 different districts, responded to the survey. Twenty-two percent of healthcare workers (including 28% of district workers of the various cadres and 31% of nurses) had never received teaching on any aspect of renal disease, and 50% (including 63% of district workers and 61% of nurses) had never received teaching specifically on AKI. Forty-four percent did not feel confident managing AKI, and 98% wanted more support managing patients with renal disease. Thirty-four percent (including 55% of district workers) were unaware that haemodialysis was available at Queen Elizabeth Central Hospital (QECH) for the treatment of AKI and 53% (74% of district workers) were unaware that peritoneal dialysis was available for the treatment of AKI in children. Only 33% had ever referred a patient with AKI to QECH. Conclusions There are deficiencies in education about, and clinical experience in, the management of AKI among Malawian healthcare workers, in addition to limited awareness of the renal service available at QECH. Urgent action is required to address these issues in order to prevent morbidity and mortality from AKI in Malawi.
