Mortality rates in the first 90 days following hip replacement surgery have halved, according to a study led by the University of Bristol on behalf of the National Joint Registry for England, Wales and Northern Ireland (NJR) and published in The Lancet.
A team of researchers led by Professor Ashley Blom from the University of Bristol have analysed data on death after hip replacement for the NJR as one of a programme of in-depth studies.
The researchers from Bristol, Oxford, East Anglia and Exeter studied 409,000 patients who had hip replacements for osteoarthritis between 2003 and 2011 and report some fascinating findings.
The study found:
Ashley Blom, Professor of Orthopaedic Surgery in the University's School of Clinical Sciences said: "It is extremely good news that the risk of death after hip replacements has reduced so dramatically in England and Wales. It is also very exciting that we can further reduce the risk of post-operative death by adopting four relatively simple measures.
"The finding that overweight people have a lower risk of death is surprising, but has been confirmed by other recent studies, and challenges some of our preconceptions. We need to concentrate efforts on reducing the risk of death in high risk groups such as those with severe liver disease."
