Development and Psychometric Analysis of a Patient-Reported Measure of Diagnostic Excellence for Emergency and Urgent Care Settings

Abstract

Background Emergency and urgent care settings face challenges with routinely obtaining performance feedback related to diagnostic care. Patients and their care partners provide an important perspective on the diagnostic process and outcome of care in these settings. We sought to develop and test psychometric properties of Patient-Report to IMprove Diagnostic Excellence in Emergency Department settings (PRIME-ED), a measure of patient-reported diagnostic excellence in these care settings. Methods We developed PRIME-ED based on literature review, expert feedback, and cognitive testing. To assess psychometric properties, we surveyed AmeriSpeak, a probability-based panel that provides sample coverage of approximately 97% of the U.S. household population, in February 2022 to adult patients, or their care partners, who had presented to an emergency department or urgent care facility within the last 30 days. Respondents rated their agreement on a 5-point Likert scale with each of 17 statements across multiple domains of patient-reported diagnostic excellence. Demographics, visit characteristics, and a subset of the Emergency Department Consumer Assessment of Healthcare Providers & Systems were also collected. We conducted psychometric testing for reliability and validity. Results Over a thousand (n = 1116) national panelists completed the PRIME-ED survey, of which 58.7% were patients and 40.9% were care partners; 49.6% received care at an emergency department and 49.9% at an urgent care facility. Responses had high internal consistency within 3 patient-reported diagnostic excellence domain groupings: diagnostic process (Cronbach’s alpha 0.94), accuracy of diagnosis (0.93), and communication of diagnosis (0.94). Domain groupings were significantly correlated with concurrent Emergency Department Consumer Assessment of Healthcare Providers & Systems items. Factor analyses substantiated 3 domain groupings. Conclusions PRIME-ED has potential as a tool for capturing patient-reported diagnostic excellence in emergency and urgent care.
