Development and validation of the Patient-Reported Outcome Measure–Older adult care Transitions from the Emergency Department (PROM-OTED) tool

Background: Care transitions from the emergency department (ED) to the community represent a critical period that can significantly impact clinical outcomes of older adults, yet there is a lack of standardized tools to measure patient-reported experiences and outcomes during this transition. Our objective was to develop and validate the Patient-Reported Outcome Measure–Older adult care Transitions in the ED (PROM-OTED) tool to measure care transition outcomes within 4–10 days after ED discharge. Methods: Older adults (65+ years) discharged from four EDs were enrolled between November 2021 and April 2024 in a multiphase process: qualitative interviews, item generation, member checking, cognitive debriefing, technical expert panel review, and psychometric evaluation and validation. We employed descriptive statistics, item analysis, interitem correlation, and factor analyses to assess the tool‘s validity and reliability. Results: Across all phases, we enrolled 290 older adults. The final 18-item PROM-OTED tool included items that addressed understanding of discharge instructions, medication management, follow-up care, and quality of life. The tool demonstrated feasibility with a mean (±SD) completion time of 4.97 (±3.04) min and was able to be administered electronically or via telephone. The tool additionally demonstrated excellent internal consistency (Cronbach‘s alpha 0.9376, McDonald‘s omega 0.9988) and good test–retest reliability (r = 0.8437). Exploratory factor analysis supported a robust factor structure and significant correlations between the PROM-OTED tool with the Care Transitions Measure-3, a general measure of hospital discharge quality of care, support its concurrent validity. Conclusions: The PROM-OTED tool is a reliable and preliminarily valid instrument for use during the immediate post-ED period, with potential clinical applications in enhancing discharge practices and assessing care transition outcomes of older adults during observational or interventional studies.
