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 the black marker ().

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 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.

QUALITY OF THE INFORMATION SUBMITTED BY THIS HOSPITAL

This information display shows whether this hospital is submitting all of 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.

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.
