HIPS – 90-DAY MORTALITY
Data for May 2018 to May 2023 Surgeon risk adjusted 90-day mortality

What does this mean?

This shows 90-day mortality following hip surgery for this surgeon, based on the type of patients this surgeon has seen.

The surgeon you are reviewing is highlighted as an orange triangle. Progression along the horizontal axis (x axis) means that the surgeon has done more cases and/or cases at a higher mortality risk such as older patients. Progression along the vertical axis (y axis) means the surgeon has had more deaths.

The vertical axis figures are presented as a standardised mortality ratio. This means the values do not represent percentages of patients who have died, but they represent the proportion of deaths compared to the national average. The data is also risk adjusted to take account of the fact that different surgeons may operate on more higher-risk or lower-risk patients e.g. because of demographics in the patient population they work with.

  • Surgeons on the central (green) horizontal line (at national average ratio figure of 1) have had exactly the average expected mortality
  • Surgeons either side of the central green line but below the upper red line have had a level of mortality that is within the expected range
  • Any surgeons that appear above the top red line which represents a Control limit (99.8%) have a mortality rate that is higher than expected.

The overall 90-day mortality rate following primary hip replacement surgery is approximately 0.24%.

ABOUT THE PATIENTS WHO WERE TREATED

This information display shows overall characteristics for first-time ankle replacement patients treated by this surgeon between 1 April 2010 and 31 March 2023. Against each characteristic you will be able to see whether this surgeon has been responsible for a greater or fewer number of patients of a particular type. This surgeon is represented on the chart by the black marker ().

The types of patients a surgeon treats can explain variation in patient outcomes after surgery. Please click on the “How to interpret this chart” button for further information.

For surgeons in England and Wales, the NJR has collected information since 2010. For surgeons in Northern Ireland since February 2013, for surgeons in the Isle of Man since July 2015 and for surgeons in Guernsey since November 2019.

If there is no profile for an individual surgeon it is likely to be because of concerns about the accuracy of the data originally supplied to the NJR and it has, therefore, been decided not to publish this surgeon's data.
