3. Target audience for our site

The Stratify-Hip website details a research tool in development. We anticipate the content of the site will be of interest to healthcare professionals such as, but not limited to, physicians, physiotherapists, and specialist nurses working with older adults during the index admission to hospital for hip fracture surgery. The Stratify Hip model(s) predicts the risk of inhospital death, 30-day death, and of a change in residence (to a higher level of dependency). The model has only been formally validated using datasets from the population of the United Kingdom (UK). The model predicts the risk of death and changing residence based on five variables: age, sex, prefracture function, prefracture residence, and dementia. Stratify Hip Model cannot be considered for any other patient group apart from adult patients over the age of 60-years. The model does not claim to be the only method to predict the risk of inhospital death, 30-day death, and of a change in residence, nor does it preclude other methods to assess these risks. The model is for information purposes only and KCL are not endorsing the use of the algorithm for any clinical management or research purpose as it is yet to be tested and/or approved as a medical device by the UK Regulator or any non-UK body.
