Summary
Patient Reported Outcome Measures (PROMs) have been collected for four conditions since 2009/10; varicose vein procedures, groin hernia procedures and hip and knee replacement operations. Patients undergoing PROMs-eligible procedures are asked to complete a questionnaire before treatment and again three to six months after treatment.
To become a complete PROMs measurement that can be used to compare performance across organisations, a number of different requirements must be met. The patient must have the operation and complete both a pre-operative (Q1) and a post-operative (Q2) questionnaire. The data quality must also be sufficient so that the measures used, such as the Oxford Hip Score are complete and the patient's identifying information must be complete enough to link the questionnaire data with the operation data sourced from their Hospital Episodes Statistics (HES) dataset. Where all of these conditions are met, the record is eligible for Casemix adjustment which allows direct comparison to other records. This is referred to as a modelled record.
The reduction in the number of useable records at each stage is known as attrition. This topic shows the numbers at each stage of the process, beginning with number of eligible episodes through to the final number of modelled records, explaining why the number of records reduces at each stage.
This topic is based on 2013/14 data, the latest year of finalised data at the time of publication.
