PATIENT IMPROVEMENT AND OUTCOMES

This information display shows you how this hospital compares to the national rates for a range of patient improvement and outcomes measures used to demonstrate quality in joint replacement surgery. Against each measure you will be able to see whether this hospital is performing better than expected, within the expected range or worse than expected for this type of surgery. This hospital is represented on the chart by a black marker or orange triangle.

It is important to note that the types of patients a hospital treats and the procedures it carries out can explain variation in patient outcomes after surgery. Please click on the “How to interpret this chart” button for further information.

 
Patient improvement

Patient improvement, featured in this chart, looks at three measures of patient-reported outcomes that are routinely assessed following hip/knee replacement in England. This information is not currently collected in Wales, Northern Ireland, the Isle of Man, Guernsey or the independent sector and as a result, no data is available to display.

The measures are referred to using their technical names 'Oxford hip/knee score', 'EQ-5D' and 'EQ-VAS' click here for a non-technical introduction to these.

ABOUT THE PATIENTS WHO WERE TREATED

This information display shows overall characteristics for first-time hip replacement patients treated at this hospital between 1 April 2003 and 31 March 2025. Against each characteristic you will be able to see whether this hospital has treated a greater or fewer number of patients of a particular type. This hospital is represented on the chart by the black marker ().

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

For hospitals in England and Wales, the NJR has collected information since 2003. For Northern Ireland since 2013, for the Isle of Man since 2015 and for Guernsey since 2019.

90-DAY MORTALITY
Data for August 2020 to August 2025 Hospital risk adjusted 90-day mortality

What does this mean?

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

The hospital you are reviewing is highlighted as an orange triangle. Progression along the horizontal axis (x axis) means that the hospital 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 hospital 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 hospitals may operate on more higher-risk or lower-risk patients e.g. because of demographics in the patient population they work with.

  • Hospitals on the central (green) horizontal line (at national average ratio figure of 1) have had exactly the average expected mortality
  • Hospitals 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 hospitals that appear above the top red line which represents a Control limit (99.8%) have a mortality rate that is higher than expected

QUALITY OF THE INFORMATION SUBMITTED BY THIS HOSPITAL

This information display shows whether this hospital is submitting all the data they should to the NJR (compliance), whether those records have corresponding patient details (patient consent) and whether the records have a valid NHS or national patient number. This is important so that the NJR can measure how long implants last and look at other areas of surgical performance.

The display also shows a result for data entry delay. This indicates whether the hospital is submitting their information in a timely way. This is important so that the NJR can report an accurate and full picture of performance to hospitals, the surgeons who work there as well as to patients and the public.

This hospital is represented on the chart by the black marker (). Please click on the “How to interpret this chart” button for further information.

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.
