1357 Patient-reported outcome measure for older people living with frailty receiving acute care (PROM-OPAC): a programme of development and field-testing

Aims, Objectives and Background Acute healthcare outcomes for older people living with frailty are not meaningfully measured using only service delivery metrics (time targets) or broad (mortality). This programme developed field-tested a novel Patient Reported Outcome Measure (PROM). Method Design 1: To define important goals, interviews were conducted during acute care. 2: A systematic review searched measures previously used in settings. These appraised content validity lay collaborators patient participants. 3: Some areas identified [1] had no existing measures, so questions devised, improved, reduced co-creation cognitive 4: The resulting feasibility psychometric performance multi-site cohort of patients. Results Conclusion outcome goals classified under Autonomy (information, security, control) Function (physical, psychosocial, symptom relief). Four sets measuring identified. EQ-5D provided the best compromise between reliability burden. There Autonomy, seven scaled. When tested 128 patients, median completion time was 12 minutes most participants required researcher assistance. Mean inter-item correlation items 0.28 adequate response distribution. Exploratory factor analysis (Table 1) indicated three-factor structure (RMSEA, 0.043) good internal consistency (Cronbach’s alpha, 0.73. Range subscales, 0.62–0.77). 35% returned post-discharge retest. Abstract 1357 Table 1 PROM-OPAC factors. Responses five-level scale (agree strongly, agree, neither agree nor disagree, disagree strongly) Summary From interviews, to measure (seven questions) (EQ5D). In-hospital follow-up collection appeared feasible, although users support overcome accessibility barriers. Validation cohorts is ongoing. Potential future applications include system-level metrics, service-level quality improvement, patient-level shared decision-making.
