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 97.7% (97.8% in 2017-18). This is also the measure with the highest percentage for revision procedures. 86.3% of patients reported an improvement in health (86.5% in 2017-18).

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, 55.0% of independent organisations were above the national average compared to 40.0% of NHS organisations. Independent organisations account for 46.6% of all organisations with 30 or more modelled records.
