Abstract
OBJECTIVE: Patient-reported experience measures (PREMs) are a key component of healthcare accountability frameworks, health policy, integrated care board commissioning and integrated care partnerships generating data which are crucial markers of patient care quality. The Rheumatoid Arthritis Patient-Reported Experience Measure (RA-PREM) incorporates the eight core elements of NHS Patient Experience Framework and is validated in a range of rheumatic conditions. Our objective is to determine the acceptability and feasibility of the RA-PREM for an interstitial lung disease (ILD) population. DESIGN: A mixed-methods patient-centred approach incorporating an interdisciplinary research steering group with patient partners. Patient surveys evaluated the language and meaning of the RA-PREM 8 domains, 24 statements and response categories. A patient focus group examined contentious statements. A consensus group of expert patient-partners agreed statements for the modified RA-PREM. Focus group participants reviewed the modified instrument (ILD-PREM) for acceptability and face/content validity. SETTING: A single NHSE-commissioned, regional ILD service/UK. RESULTS: Thirteen patients (10 male) diagnosed with ILD participated in focus group discussions. Critical discussion of the RA-PREM resulted in nuanced modifications of four statements of three domains. Five patients (three male) and three healthcare researchers attained consensus on the face/content validity of statements. Seventy-three patients completed the ILD-PREM following outpatient contact. CONCLUSION: The ILD-PREM retains 24 statements representing the eight domains of the RA-PREM. It meets face/content validity criteria and is acceptable to an ILD population. Longitudinal validation of the ILD-PREM across ILD services including further testing in global minority groups will establish criterion and construct validity and objective measures of reliability.
