Validity of a first draft PROM (PROM-CR1) at the start of the outpatient cardiac rehabilitation programme. (2nd July 2019) - Cowie, Aynsley
Abstract : Background/Aims: A 40-item first draft PROM (PROM-CR1) had previously been developed for use in cardiac rehabilitation. This article details how PROM-CR1 was tested for item relevance, and for acceptability and validity when used at an initial CR outpatient appointment. Methods: Cardiac rehabilitation staff rated the relevance of all 40 items. The PROM-CR1 was then piloted across 185 service users (mean age 67.24 years; 147 males/40 females; referred with a range of cardiac diagnoses) who completed the tool at their initial cardiac rehabilitation outpatient appointment. Results: Analyses of item relevance and construct validity flagged nine items requiring removal from the tool; all other items and scores performed well in these tests. PROM-CR1 demonstrated good concurrent and discriminant validity, and its performance improved with the flagged items removed. Conclusions: The 31-item version of PROM-CR1 will be re-tested when applied at the end of outpatient CR and refined into a finalised tool (PROM-CR) for clinical practice.
