HIPPY - Factors influencing outcomes and costs for hip replacement in younger people using routine databases
What we are doing
In this work package we will be investigating how likely people under 70 years old are to need further revision surgery by looking at historical data from people who had a hip replacement in the past. We will also estimate how much these hip replacements and treatments after hip replacement cost the NHS over their remaining lifetime. We will compare those who received cemented implants, with those who received hybrid or uncemented implants. We will also look at how other personal characteristics, surgical, or hospital-factors may have influenced outcomes and costs and whether these are different between the younger and older people having hip replacement.
How we are doing it
We will use information as recorded in the national databases of routinely collected data, like the National Joint Registry (NJR) and linking this information to anonymised patients’ hospital records. We will use statistical and economic modelling methods to address common biases and challenges that often arise when using these types of databases.
What we hope to achieve
Although the results from these analyses are not as accurate as the ones we will get from the HIPPY trial, they will have the advantage of looking at over 1 million people who had hip replacement in the UK over the past 20 years and help us guide decisions a bit sooner than our trial can.
These findings will complement the picture of our HIPPY trial findings and the economic analyses to look at which implants are most cost-effective in the longer term.
