Description

Abstrat publicado em: http://www.springerlink.com/content/45745132180p7215/fulltext.pdf Background: Hip fractures related to osteoporosis and falls in elderly are an important cause of decreased health state. After Hip fracture older adults have a 5 to 8-fol increased risk of all-cause mortality, a 2.5-fold increase risk for the development of a new fracture and the majority of patients never regain previous level of independence. In Portugal, during 2006, Direcção Geral da Saúde (DGS) estimated that 52 million Euros were spending in hospitals direct costs related with Hip fractures, with a medium cost of 4.100 Euros per hospitalization. Objectives: Estimate the annual incidence of Hip fractures; describe the evolution between 2004 and 2010 Methods: Using Administração Central dos Sistemas de Saúde (ACSS) information from Hospitals Discharges (GHD) database, Hospitalization with code 8200 to 8201 (Classification of Diseases 9th Revision Clinical Modification – ICD-9-CM) as the main cause (DDX1) of hospitalization were considered as being due to hip fracture. Number of hospitalization by hip fracture were analyzed considering age (65-74 years, 75-84 years and ≥ 85 years) and sex of the patients. Incidence rates and respective confidence intervals for the hospitalization hip fracture were estimated for each age group and gender. For each age group and year official data (from Statistics Portugal) was considered as the number of people at risk of being hospitalized by a hip fracture. Results: For the group aged 65-74 years incidence rate varied between 0.49 by 1000 Persons-year of follow-up (PYFU) [95% confidence-interval (95%CI): 0.45; 0.54) in 2010 and 0.65 by 1000 PYFU (95%CI: 0.60; 0.70) in 2004. For the group aged 75-84 years incidence rate varied between 1.99 by 1000 PYFU (95%CI: 1.89; 2.10) in 2010 and 2.41 by 1000 PYFU (95%CI: 2.30; 2.54) in 2006 and 2007. Considering people aged 85 or more incidence were highest in 2009 [6.86/1000 PYFU (95%CI: 6.50; 7.24)] and lowest in 2010 [6.09/1000 PYFU (95%CI: 5.75; 6.44)]. As far as the difference between sexes are concerned risk of hospitalization by hip fracture is approximately twice in women of all ages above 65 years comparing with men of the same age. Conclusions: The incidence rate of hospitalization discharges by hip fracture has been constant in the analyzed years. Further analysis is needed in order to understand the reasons on this phenomenon. Being an important cause of fracture we highlight the importance of fall prevention in this population.
