Patient Reported Outcome Measures (PROMs) in England, Final 2023/24 data
Official statistics
Summary
Patients undergoing elective inpatient surgery for hip and knee replacement, 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. This publication is for Finalised Patient Reported Outcome Measures (PROMs) in England - April 2023 to March 2024.
It is possible that the response rates could still be impacted by the COVID-19 pandemic. The response levels may be also been impacted by a reduction in resource at NHSE in recent years. We will monitor the number questionnaires arriving to late for this publication and will consider revising key figures if a large volume are received.
In analysing outcomes driven by the difference in pre-operative and post-operative questionnaires, please note that some data breakdowns or analyses are dependent on questionnaire pairs being linked to operations in Hospital Episode Statistics (HES) while others are not. As shown in the data quality section, not all questionnaire pairs link to HES, for reasons including correct patient identifiers not being returned or data inconsistencies. This means that the breakdowns that are dependent on linkage to HES, including by primary/revision, commissioner, or any casemix adjusted score comparisons will have lower totals than those not dependent on linkage to HES such as grand totals or some provider-level outputs.
In addition, the report presents both adjusted and non-adjusted figures and this should be borne in mind when summarising any findings. There may also be some disparities in the way figures are calculated across products. *** Update 20/3/25: We are currently investigating some issues with the way the modelled records are constructed and will provide an update in due course.
A small number of provider and site codes rolled out in the last few years, particularly those in the ANANA format, are not recognised or correctly processed by the system and they are mapped inconsistently to codes for different publication measures. They are typically given an organisation name of unknown in the interest of making the data available in a timely manner. Subject to user demand, we anticipate that the system will be developed to address this issue ahead of subsequent publications.
*** The Summary Comparison Tool published on the 13th February 2025 contained missing formula for pre-operative participation and linkage rate and post-operative issue and response rate in the Key Facts tab. The formulas have now been reintroduced and corrected (19th February 2025).
