Changes to our Score Comparison tool from August 2014
Following feedback received from users, we are considering making a small change to our quarterly Score Comparison tool (next scheduled for release with our August 2014 publications) to reduce confusion: we would no longer include the 'Key Facts Chart' tab which shows raw percentages by provider of 'improved' and 'worsened' questionnaire pairs.
We will continue to include all statistically-adjusted figures and visualisations, which allow for statistically valid comparisons, and the unadjusted figures that are included in the 'Select 10' tab; the unadjusted percentages will also be available in the CSV data files should any users require these, although we would continue to caution against drawing any conclusions from comparisons of these unadjusted figures.
If you have any concerns about these proposals, please let us know by reaching out to our Contact Centre at 0845 300 6016 or firstname.lastname@example.org (please include 'PROMs' in the email subject line).
For the coverage period 1 April 2012 to 31 March 2013.
Participation and Coverage
- There were 241,407 PROMs-eligible procedures carried out in hospitals1 and 181,513 pre-operative questionnaires returned so far, a headline participation rate of 75.2 per cent (74.7 per cent for 2011-12).
- For the 181,513 pre-operative questionnaires returned, 173,598 post-operative questionnaires were sent out2, of which 127,402 have been returned so far - a return rate of 73.4 per cent3 (79.6 per cent for 2011-12).
Comparing pre- and post-operative 'EQ-5D Index' scores (a combination of five key criteria concerning patients' self-reported general health), an increase in general health was recorded for:
- 49.4 per cent of groin hernia respondents (49.9 per cent for 2011-12)
- 87.9 per cent of hip replacement respondents (87.3 per cent for 2011-12)
- 79.7 per cent of knee replacement respondents (78.4 per cent for 2011-12)
- 52.8 per cent of varicose vein respondents (53.2 per cent for 2011-12)
Comparing pre- and post-operative 'EQ-VAS' values (the current state of the patient's self-reported general health), an increase in general health was recorded for:
- 37.4 per cent of groin hernia respondents (38.9 per cent for 2011-12)
- 64.2 per cent of hip replacement respondents (63.6 per cent for 2011-12)
- 54.6 per cent of knee replacement respondents (53.8 per cent for 2011-12)
- 41.2 per cent of varicose vein respondents (42.0 per cent for 2011-12)
Comparing pre- and post-operative responses to condition-specific questions, improvements in patients' conditions were recorded for:
- There is no condition-specific scoring for groin hernia patients.
- 95.8 per cent of hip replacement respondents (95.7 per cent for 2011-12) ['Oxford Hip Score']
- 92.3 per cent of knee replacement respondents (91.6 per cent for 2011-12) ['Oxford Knee Score']
- 83.0 per cent of varicose vein respondents (83.1 per cent for 2011-12) ['Aberdeen Varicose Vein Questionnaire']
- An 'eligible procedure' is counted for each episode in HES in the period in question which has been clinically coded with relevant hip, knee, varicose vein or groin hernia OPCS procedure codes which make it suitable for inclusion in PROMs. Some patients may have undergone more than one PROMs procedure in a single eligible episode, hence there will be more procedures than episodes: this is the case for 48 of the 241,407 procedures.
- Not every pre-operative questionnaire will have a post-operative questionnaire sent out, for various reasons including the cancellation of an operation or the death of the patient.
- This will be an underestimate of the true rate due to the time delay in returning post-operative questionnaires.
