Time-series Analysis: PROMs from 2009-10 to 2014-15

Publication date: 09:30 November 12, 2015

Summary

This topic of interest reviews finalised published PROMs data for five years between 2009/10 and 2013/14, with additional provisional data for 2014/15. The data are shown at individual provider and England total levels by each of the four PROMs-eligible procedures and their measures.


Update 10/11/2016: This publication has been updated since initial publication in November 2015 in order to rectify problems with the data discovered within the interactive spreadsheet. Data within the 'complications' and 'adjusted health gain' sections of the spreadsheet were found to be incorrect. Data within the 'modelled records' section of the topic and the regular quarterly PROMs publication published on the same day are unaffected.


A time series analysis has been created, looking specifically at:

  • Linkage and Participation- the numbers and proportions of people who have returned matched pre- and post-operative questionnaires compared to the numbers who underwent each of the PROMs surgical procedures.
  • Adjusted Average Health Gain- the improvement or otherwise of the levels of well-being, mobility and ability to carry out day to day tasks, measured via two questionnaires, one prior to and one following the given surgical procedure. There is an allowance of time for recovery before the post-operative questionnaire is sent, which varies depending on the procedure.
  • Complications- the count and proportion of people who experienced complications following their surgery, categorised into four groups: allergy to drugs administered; bleeding; urinary, and wound problems (e.g. infection). Further to this, data are provided showing re-admissions and where further surgery has been required.

For each of the three available datasets, a provider can be selected from the dropdown boxes, along with the chosen procedure and one of the given measures. The data for the provider are then compared to the average for England.

Some fields, where the user might expect to see data, are showing "*". This may be as a result of either primary suppression (figures are 5 or less and there is a risk of identification of individual patients) or secondary suppression (used on the next smallest number, so that the primary suppression is not disclosed). We have provided the data exactly as they were published to comply with the suppression policy used at the time of release.


Key Facts

Linkage and Participation

  • Participation in PROMs has increased steadily since the programme began from just over 66 percent in 2009/10 to a maximum of 76 percent in 2013/14.
  • The overall rate has decreased slightly in 2014/15 although this is still provisional.
  • Post-operative response rates have decreased for all procedures since PROMs began in 2009/10, with the decrease varying between procedure.
  • When compared with the most recent finalised year (2013/14) the hip return rate has fallen the least at 6.2 percentage points whilst the largest drop was seen for varicose veins at just over 10 percentage points.

Adjusted Average Health Gain

  • The condition specific scores for hip and knee replacement (the Oxford Hip and Knee scores) have shown a small but steady year on year increase since 2009/10.
  • Varicose veins as measured by the Aberdeen Varicose Vein Questionnaire show an overall increase since the beginning of the programme although the scores fluctuate year on year.
  • Analysis of the year on year changes in the EQ-5D Index show a similar pattern to the condition specific scores.
  • Although all procedures score higher in 2014/15 than in 2009/10, hip and knee patients show a more consistent year on year change whilst groin hernia and varicose veins show more fluctuation.
  • Hip and knee replacement patients show a steady increase in health gain as measured by the Visual Analogue Scale (VAS).
  • Groin hernia and varicose vein patients' scores fluctuate year on year with no overall upward or downward trend.

Complications

  • Although there are differences between procedures when looking at patient reported complications after surgery (such as allergic reaction to a drug, bleeding or wound problems), the proportions reporting such complications have remained steady over the years since the PROMs programme began.
  • Whilst there are some differences year on year for these complications, there are no consistent upward or downward trends.
