hip fracture is expensive in terms of mortality, hospital length stay (LOS) and consequences for independence. Poor outcome reflects the vulnerability patients who typically sustain this injury, but impact different comorbidities impairments complex to understand. We consider a prospective cohort study designed examine how patients' frailty index (FI) predicts outcome.consecutive with low trauma were assessed, excluding only those unfit surgery. Comprehensive Geriatric Assessment (CGA)...

We re-analysed prospective data collected by anaesthetists in the Anaesthesia Sprint Audit of Practice (ASAP 1) order to describe associations with linked outcome data.Mortality was 165/11,085 (1.5%) 5 days and 563/11,085 (5.1%) 30 after surgery not associated anaesthetic technique (general vs spinal, or without peripheral nerve blockade).The risk death increased as blood pressure fell: odds ratio (95% CI) for mortality within 0.983 (0.973-0.994) each mmHg intra-operative increment systolic...

SUMMARYThe prevalence of osteoporosis increases with age. The over-50-year-old population is expected to grow by 10% and 25% 2010 2020, respectively. There are already 3 million UK residents the public health impact will increase substantially over next 20 years. A Markov model natural history was used predict fracture numbers corresponding costs for aged 50-99 from 2000 2020. predicts 190,000 osteoporosis-related fractures at a cost £1.8 billion in 2000. By annual osteoporotic 21% 230,000...

<ns3:p>Background Delirium and cognitive impairment are common in hip fracture populations associated with significant adverse patient outcomes. National registries facilitate improvements outcomes care quality, such as reduced mortality the development of specialist multidisciplinary services. However, there is substantial variation data collected reported relation to delirium cognition, which impedes international comparison may reduce quality care. Objective This scoping review aims...
