Primary and Revision Hip Replacements

Where questionnaires have linked to an episode from the Hospital Episode Statistics data set, the procedure can be split into primary or revision hip replacements. The chart below shows the percentage of patients that reported an improvement in health. For primary procedures, the Oxford Hip Score shows the highest percentage with 97.9% (97.5% in 2019-20). This is also the measure with the highest percentage for revision procedures. 89.1% of patients reported an improvement in health (88.4% in 2019-20).

For revision procedures, the average health gain increased for the Oxford Hip Score and EQ-5D Index compared to last year (14.2 for Oxford Hip Score and 0.314 for EQ-5D Index in 2019-20) whilst the EQ VAS stayed almost the same (8.0 in 2019-20).


Results by Sector

Whilst the national PROMs programme collects data for NHS funded activity only, patients can be treated at either NHS or independent sector organisations. This may be due to patient choice or subcontracting arrangements between organisations.

The proportion of providers with a reported organisational average health gain above the national average is higher for independent providers than providers in the NHS.

For primary hip replacements, 58.0% of independent organisations were above the national average compared to 39.5% of NHS organisations. Independent organisations account for 47.5% of all organisations with 30 or more modelled records.
