- Time to death in a prospective cohort of 252 patients treated for fracture of the proximal femur in a major hospital in PortugalPublication . Campos, Sónia; Alves, Sandra Maria; Carvalho, Marilia Sá; Neves, Nuno; Trigo-Cabral, Abel; Pina, Maria FátimaThe objectives were to analyze one-year survival and mortality predictors in patients with fracture of the proximal femur (low/moderate trauma). A prospective cohort was formed by inviting all patients hospitalized in the Orthopedic Ward of the second largest hospital in Portugal (May 2008-April 2009). Survival was assessed at 3, 6, 9, and 12 months after fracture and related to demographic factors, lifestyle, and clinical history, as well as to data from medical records (fracture type, surgery date, surgical treatment, and preoperative risk). Of the 340 patients hospitalized, 252 were included (78.9% women). Mortality at 3, 6, 9, and 12 months was 21.2%, 25%, 28.8%, and 34.6% for men and 7.8%, 13.5%, 19.2%, and 21.4% for women, respectively. Predictors of death were male gender (HR = 2.54; 95%CI: 1.40-4.58), ASA score III/IV vs. I/II (HR = 1.95; 95%CI: 1.10-3.47), age (HR = 1.06; 95%CI: 1.03-1.10), and delay in days to surgery (HR = 1.07; 95%CI: 1.03-1.12). Factors related to death were mainly related to patients' characteristics at admission.
- Survival in the elderly following a proximal femur fracture: one-year follow-up studyPublication . Campos, Sónia; Alves, Sandra Maria; Cabral, Abel Trigo; Pina, Maria FátimaThe aim of this study was to determine the one year survival rate after a proximal femur fracture and to investigate the predictors for fatality. All patients that were admitted, with an acute proximal femur fracture caused by a fall of low energy impact from 1 May 2008 - 30 April 2009 in a main portuguese hospital were invited to participate in the study.
- Regional drinking water composition effects on hip fracture risk: a spatial analysis of nationwide hospital admissions in Portugal, from 2000 to 2010Publication . Oliveira, Carla Maria; Teixeira, Hugo; Alves, Sandra Maria; Pina, Maria FátimaA variabilidade espacial existente na fratura do colo do fêmur (FCF) pode estar relacionada com a variabilidade geográfica da composição da água para consumo (CAC), devido à ação dos minerais na fragilidade óssea. O objetivo do artigo foi investigar o efeito da CAC no risco de FCF em Portugal (2000-2010). Do registo nacional de altas hospitalares, foram selecionadas todas as admissões em indivíduos ≥50, com diagnóstico de FCF causado por trauma de baixo/moderado impacto. Os componentes e características da água foram usados ao nível do município. Um modelo espacial aditivo generalizado, com a distribuição binomial negativa como função de ligação, foi usado para estimar a associação de FCF e as variações da CAC. Foram selecionadas 96.905 FCF (77,3% em mulheres).
- Spatial pattern of hospitalizations due to low impact falls in Portugal: exploratory analysisPublication . Bessa, Ana Cristina; Alves, Sandra Maria; Pina, Maria Fátima; Alves, Sandra MariaLow impact falls result from low energy (falling from a chair or tripping on a mat), Female sex (up to 60/70%) and increase age (mean age of 80.3 years ± 8.7) are identified as risk factors falling. The continual increase of the elderly population worldwide poses as a problem to healthcare systems as theoretical there will be more individuals needing health assistance after suffering a fall. Despite extensive research and preventive efforts, accidental falls continues to be a massive health problem as in the elderly falls are a leading cause of severe injury requiring acute care or causing death. It is important to identify the spatial pattern to understand what is causing the increase and to plan awareness campaigns. We aim to identify the spatial pattern of hospitalizations due to low impact falls, in individuals over 65 years old in Continental Portugal (2000, 2007 and 2013).
- Spatial-temporal analysis of climate factors effects on hospitalization due to fallsPublication . Oliveira, Carla Maria; Alves, Sandra Maria; Bessa, Ana Catarina; Pina, Maria Fátima; Alves, Sandra Maria; Oliveira, Carla MariaA higher risk of falls in winter, when compared to summer, has been reported, although climatic factors as risk factors for falls have been little studied. Our aim is to identify the effects of climatic factors (CF) on the spatial-temporal distribution of hospitalization for fall-related injuries in older adults (2000-2010).
