Co-medications, pre-medication and common diseases in the elderly

[Hip fracture surgery in the elderly patient: epidemiological data and risk factors]

Health care administration is concerned about the escalating cost of geriatric trauma care and more specifically hip fracture (HF). By 2050, the wordwide annual incidence of HF among elderly people will be 4.5 million (predictible incidence in France: 150,000) and prevention will be more important than ever. The risk of hip fracture in older people increases exponentially with age. The main other risk factors are osteoporosis and osteopenia, gender, weight, physical activity. The most important cause of osteoporosis is the gradual bone loss that occurs after the menopause. Similarly, there is a strong association with gender: the female-to-male ratio of HF is greater than 2/1 in people over 50 years of age (mean age: 83.2 yrs in female and 79.6 yrs in male in France). One year mortality after hip fracture is remarkably high, around 20 to 30%.

Präoperative Dauertherapie

A large number of patients undergoing elective surgical procedures already take routine medication preoperatively. The majority of these patients use drugs for therapy of preexisting cardiovascular, pulmonary or endocrinological diseases which are independent of the planned surgical procedure. The number and type of preoperative drug therapy are correlated to age, gender and co-morbidity of the patients. Furthermore, patients with higher ASA-classes usually take more drugs, as they suffer from several medical diseases. Information about the perioperative handling of routine drug therapy is important for the planning of anaesthesia and surgery. A close cooperation of all medical specialities involved is necessary, in particular when patients take anticoagulants or other substances which should be withdrawn or replaced. This review focuses on the handling of routine preoperative medication by the anaesthesiologist in the light of available literature.
