Patient-Reported Experience Measures in Vascular Surgery Enhancement (PREMIERE) study: protocol for a mixed-methods study to develop and validate a vascular surgery-specific patient-reported experience measure.

Abstract

Patient-reported experience measures (PREMs) capture patients' healthcare journey experiences. No validated PREMs are specific to vascular surgery patients. This study aims to develop and validate a vascular surgery-specific PREM to assess patient experience and satisfaction. Patient Reported Experience Measures In Vascular Surgery Enhancement Study is a two-phase multisite sequential mixed-methods study. The qualitative phase will develop a draft PREM; the quantitative phase will validate it. The study will be conducted across three major vascular units in Wales. Up to 40 patients and healthcare professionals will participate in the qualitative phase. Approximately 150-200 patients will be recruited for the quantitative validation. Inclusion criteria are: (1) age ≥18; (2) recent vascular procedure; (3) inpatient vascular care; (4) not cognitively impaired; (5) consent to participate and (6) English or Welsh proficiency. Primary outcomes will be construct validity and reliability. Secondary outcomes will include patient engagement, healthcare provider perspectives and health system impacts. Thematic analysis will be conducted using NVivo. Psychometric validation will include item analysis, internal consistency testing and factor analysis. The study was approved by the London-Camberwell St Giles Research Ethics Committee, coordinated by the Health Research Authority and Health and Care Research Wales (REC reference: 24/PR/0522). NCT06363175.
