Finalised Patient Reported Outcome Measures (PROMs) in England - April 2012 to March 2013
Patients undergoing elective inpatient surgery for four common elective procedures (hip and knee replacement, varicose vein surgery and groin hernia surgery) funded by the English NHS are asked to complete questionnaires before and after their operations to assess improvement in health as perceived by the patients themselves.
Extended analyses of the latest finalised data are published three times a year as 'special topics'. The latest, EQ-5D™ Index Analysis, was published on 8 May 2014.

Participation and Coverage
There were 241,433 PROMs-eligible procedures carried out in hospitals1 and 182,173 pre-operative questionnaires returned, a headline participation rate of 75.5 per cent (74.7 per cent for 2011-12).
For the 182,173 pre-operative questionnaires returned, 174,026 post-operative questionnaires were sent out2, of which 127,633 have been returned - a return rate of 73.3 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)
52.7 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']
82.9 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 241,433 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.
