This is the latest publication of provisional post-operatives scores from the Patient Reported Outcome Measures (PROMs) programme for the period April 2011 to May 2011. This publication considers the change in patients' self-reported health status for the four common elective surgical procedures in the PROMs programme: groin hernia surgery, hip replacement, knee replacement and varicose vein surgery. Analysis covers the period from April 2011 to May 2011 and includes pre-operative questionnaires that all English providers treating NHS patients have been asked to collect from patients who wish to participate and post-operative questionnaires returned by patients following their surgery. Not all patients undergoing the relevant operations returned questionnaires for a variety of reasons.

Key Facts

In the period from April 2011 to May 2011:

  • There were 36,948 eligible1 hospital episodes and 26,538 pre-operative questionnaires returned - a headline participation rate of 71.3 per cent, which is an increase of 5.3 percentage points compared to 2009-10.

  • Of the 4,283 post-operative questionnaire sent out, 1,666 have been returned - a return rate of 38.9 per cent2,3.

  • 83.6 per cent of varicose vein respondents recorded varicose vein related improvements following their operation as measured by their response to a series of questions about their condition (Aberdeen Varicose Vein Questionnaire score). This value was 83.4 per cent in the finalised data for 2009-10. 4

  • 53.0 per cent of groin hernia respondents and 50.1 per cent of varicose vein respondents recorded an increase in their general health following their operation, based on a combination of five key criteria concerning their general health (EQ-5D Index score). These values were 49.3 per cent and 52.4 per cent respectively in the finalised data for 2009-10.

  • 41.3 per cent of varicose vein respondents and 41.3 per cent of groin hernia respondents recorded an increase in their EQ-VAS score (current state of the patients general health marked on a visual analogue scale). These values were 40.4 per cent and 38.2 per cent respectively in the finalised data for 2009-10. 

  • Footnotes


    1. An 'eligible episode' is an episode in HES in the period in question, clinically coded with relevant hip, knee, varicose vein or groin hernia OPCS procedure codes which make it suitable for inclusion into PROMs.

    2. Not every pre-operative questionnaire will have a post-operative questionnaire sent out. This may be for a number of reasons including the cancellation of an operative or the death of the patient.

    3. This will be an underestimate of the true rate due to the time delay in returning the post-operative questionnaire.

    4. Due to the length of time before post-operative questionnaires are sent out for hip and knee replacements, no unadjusted scores are currently available.
