Health Gain for Hip Replacements
Total Hip Replacements
Since 2010-11, the percentage of patients reporting an improvement in health has increased for all questionnaires relating to hip replacements. The EQ VAS has shown the highest increase, from 61.4% in 2010-11 to 70.1% in 2021-22. The percentage reporting an improvement is a small increase from last year (69.7% in 2020-21).

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 97.3% (97.9% in 2020-21). This is also the measure with the highest percentage for revision procedures. 86.7% of patients reported an improvement in health (89.1% in 2020-21).

When comparing to last year, the average health gains for primary procedures have decreased slightly for all of the measures (23.0 for Oxford Hip Score, 0.472 for EQ-5D Index and 15.1 for EQ VAS in 2020-21). For revision procedures, the average health gain decreased for the Oxford Hip Score and EQ-5D Index compared to last year (15.5 for Oxford Hip Score and 0.333 for EQ-5D Index in 2020-21) whilst the EQ VAS increased (7.8 in 2020-21).
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, 71.2% of independent organisations were above the national average compared to 40.8% of NHS organisations. Independent organisations account for 46.5% of all organisations with 30 or more modelled records.
