PATIENT OUTCOMES

This information display shows you how this hospital compares to the national rates for a range of patient 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 red 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.

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.
