Determinants of survival in very low birth weight neonates in a public sector hospital in Johannesburg

<p>Abstract</p> <p>Background</p> <p>Audit of disease and mortality patterns provides essential information for health budgeting and planning, as well as a benchmark for comparison. Neonatal mortality accounts for about 1/3 of deaths < 5 years of age and very low birth weight (VLBW) mortality for approximately 1/3 of neonatal mortality. Intervention programs must be based on reliable statistics applicable to the local setting; First World data cannot be used in a Third World setting. Many neonatal units participate in the Vermont Oxford Network (VON); limited resources prevent a significant number of large neonatal units from developing countries taking part, hence data from such units is lacking. The purpose of this study was to provide reliable, recent statistics relevant to a developing African country, useful for guiding neonatal interventions in that setting.</p> <p>Methods</p> <p>This was a retrospective chart review of 474 VLBW infants admitted within 24 hours of birth, between 1 July 2006 and 30 June 2007, to the neonatal unit of Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) in Johannesburg, South Africa. Binary outcome logistic regression on individual variables and multiple logistic regression was done to identify those factors determining survival.</p> <p>Results</p> <p>Overall survival was 70.5%. Survival of infants below 1001 grams birth weight was 34.9% compared to 85.8% for those between 1001 and 1500 grams at birth. The main determinant of survival was birth weight with an adjusted survival odds ratio of 23.44 (95% CI: 11.22 - 49.00) for babies weighing between 1001 and 1500 grams compared to those weighing below 1001 grams. Other predictors of survival were gender (OR 3. 21; 95% CI 1.6 - 6.3), birth before arrival at the hospital (BBA) (OR 0.23; 95% CI: 0.08 - 0.69), necrotising enterocolitis (NEC) (OR 0.06; 95% CI: 0.02 - 0.20), hypotension (OR 0.05; 95% CI 0.01 - 0.21) and nasal continuous positive airways pressure (NCPAP) (OR 4.58; 95% CI 1.58 - 13.31).</p> <p>Conclusions</p> <p>Survival rates compare favourably with other developing countries, but can be improved; especially in infants < 1001 grams birth weight. Resources need to be allocated to preventing the birth of VLBW babies outside hospital, early neonatal resuscitation, provision of NCPAP and prevention of NEC.</p

Approaches to economic evaluations of stroke rehabilitation

Many stroke rehabilitation services and interventions are complex in that they involve a number of components, interactions, and outcomes. Much of the onus of stroke care lies with rehabilitation services and because stroke rehabilitation is highly resource intensive, it is important for policy makers to consider the potential trade-offs between all relevant costs and benefits. The primary aim of this systematic review was to assess the methods used to conduct economic evaluations of stroke rehabilitation. Studies that compared two or more alternative stroke rehabilitation interventions or services with the costs and outcomes being examined for each alternative were included. EMBASE, MEDLINE In-Process, and National Health Service's Economic Evaluation Database were searched using search strategies. The methodological quality of the included studies was appraised using a checklist for the conduct and reporting of economic evaluations. Twenty-one studies met the selection criteria. The economic evaluations in the majority of these studies were inadequate based on their ability to identify, measure, and value all resources and benefits pertinent to the complexity of stroke rehabilitation. This study highlights that complex interventions such as stroke rehabilitation have widespread effects, which may not be represented by the changes on a single outcome. This study recommends the adoption of a wider cost and benefit perspective in the economic evaluations of complex interventions. It supports a move away from conventional economic evaluation and decision making, based purely on cost-effectiveness, toward multicriteria decision analysis frameworks for complex interventions, where a broader range of criteria may be assessed by policy makers

Low health-related quality of life in school-aged children in Tonga, a lower-middle income country in the South Pacific

Background: Ensuring a good life for all parts of the population, including children, is high on the public health agenda in most countries around the world. Information about children's perception of their health-related quality of life (HRQoL) and its socio-demographic distribution is, however, limited and almost exclusively reliant on data from Western higher income countries. Objectives: To investigate HRQoL in schoolchildren in Tonga, a lower income South Pacific Island country, and to compare this to HRQoL of children in other countries, including Tongan children living in New Zealand, a high-income country in the same region. Design: A cross-sectional study from Tonga addressing all secondary schoolchildren (11–18 years old) on the outer island of Vava'u and in three districts of the main island of Tongatapu (2,164 participants). A comparison group drawn from the literature comprised children in 18 higher income and one lower income country (Fiji). A specific New Zealand comparison group involved all children of Tongan descendent at six South Auckland secondary schools (830 participants). HRQoL was assessed by the self-report Pediatric Quality of Life Inventory 4.0. Results: HRQoL in Tonga was overall similar in girls and boys, but somewhat lower in children below 15 years of age. The children in Tonga experienced lower HRQoL than the children in all of the 19 comparison countries, with a large difference between children in Tonga and the higher income countries (Cohen's d 1.0) and a small difference between Tonga and the lower income country Fiji (Cohen's d 0.3). The children in Tonga also experienced lower HRQoL than Tongan children living in New Zealand (Cohen's d 0.6). Conclusion: The results reveal worrisome low HRQoL in children in Tonga and point towards a potential general pattern of low HRQoL in children living in lower income countries, or, alternatively, in the South Pacific Island countries

Análise da produção científica acerca da atenção ao recém-nascido de baixo peso em UTI

O objetivo deste estudo foi analisar a natureza e tendência dos artigos na temática saúde do recém nascido de baixo peso. Trata-se de uma revisão integrativa desenvolvida em agosto de 2009, a partir dos descritores: “recémnascido de baixo peso” or “recém-nascido de muito baixo peso” and “unidades de terapia intensiva neonatal”, no recorte temporal 1990-2008. A amostra de 608 resumos foi submetida à análise de conteúdo temática. Nos resultados, os estudos de natureza clínico-epidemiológica contemplam os fatores de risco do baixo peso e morbimortalidade neonatal e os de tendência assistencial contribuem com as rotinas e cuidados prestados. Evidenciam-se os avanços na atenção a saúde do recém-nascido, a complexidade clínica e as implicações para sua assistência. Destaca-se a lacuna de pesquisas que aponte a subjetividade, o apoio e a inclusão das famílias nos cuidados e no enfrentamento dessa situação
