KNEES - 90-DAY MORTALITY

This shows the 90-day mortality rate following surgery for this surgeon based on the type of patients this surgeon has seen. The data is risk adjusted to take account of the fact that different surgeons may operate on higher-risk or lower-risk patients (e.g. because of demographics in the patient population they work with). It should be noted that the mortality rate after hip and knee replacement surgery is influenced by many factors outside the control of the operating surgeon. Case-mix adjustment is a useful tool but as with any methodological approach it cannot account for all differences including those that may be due to random events.
The analysis comprises primary operations carried out between May 2018 and May 2023 (follow-up has been censored at this time point). The unit of analysis is the primary implant but where there were bilateral primary procedures (on the same day), only one has been included in the analysis. Instances have occurred in which a primary procedure was performed on a patient within 90 days of a previous primary procedure (of the same type, i.e. hip or knee) although not on the same day. Whilst both sides were included in the analysis, in a small number of cases the patient died within 90 days of both the first and the second primary procedure, leading to the patient’s death being counted twice for the given consultant.

What does this mean?

This shows 90-day mortality following knee 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 knee replacement surgery is approximately 0.21%.
