OBJECTIVE: To assess the impact of a social marketing programme for distributing nets treated with insecticide on malarial parasitaemia and anaemia in very young children in an area of high malaria transmission. DESIGN: Community cross sectional study. Annual, cross sectional data were collected at the beginning of the social marketing campaign (1997) and the subsequent two years. Net ownership and other risk and confounding factors were assessed with a questionnaire. Blood samples were taken from the children to assess prevalence of parasitaemia and haemoglobin levels. SETTING: 18 villages in the Kilombero and Ulanga districts of southwestern Tanzania. PARTICIPANTS: A random sample of children aged under 2 years. MAIN OUTCOME MEASURES: The presence of any parasitaemia in the peripheral blood sample and the presence of anaemia (classified as a haemoglobin level of <80 g/l). RESULTS: Ownership of nets increased rapidly (treated or not treated nets: from 58% to 83%; treated nets: from 10% to 61%). The mean haemoglobin level rose from 80 g/l to 89 g/l in the study children in the successive surveys. Overall, the prevalence of anaemia in the study population decreased from 49% to 26% in the two years studied. Treated nets had a protective efficacy of 62% (95% confidence interval 38% to 77%) on the prevalence of parasitaemia and of 63% (27% to 82%) on anaemia. CONCLUSIONS: These results show that nets treated with insecticide have a substantial impact on morbidity when distributed in a public health setting.
Effective patient positioning has been an important issue throughout the history of the nursing profession. Pressure ulcers result from prolonged pressure, which causes skin, tissue, or muscle damage. Surgical patients present a unique challenge in preventing pressure ulcers because they are immobile and unable to perceive the discomfort of prolonged pressure. The purpose of this integrative review is to examine risk factors associated with pressure ulcer development in surgical patients and to examine pressure-relieving support surfaces to determine if they significantly reduce intraoperative tissue pressure and result in a lower incidence of postoperative pressure ulcers. Most of the research focuses on long-term care units, with little attention given to the acute care setting. Although the pathophysiology and etiology of pressure ulcers are well documented by years of research, the OR as an etiologic factor is largely undefined.
