Patient-reported outcome and experience measures in geriatric emergency medicine.

Older people with frailty and health crises have complex physical and social needs. Modern emergency care systems are fast-flowing, using protocols optimised for single-problem presentations. Systems must incorporate individualised care to best serve people with multiple problems. Healthcare quality is typically appraised with service metrics, such as department length of stay and mortality. Worldwide, patient-reported outcome measures (PROM) and patient-reported experience measures (PREM) are increasingly used in research, service development and performance evaluation, paving the ground for their use to support individual clinical decision-making. The PROMs and PREMs are person-centred metrics, which inform healthcare decisions at the individual level and which at the strategic level drive improvement through comparison of interprovider effectiveness. To date, there is no PROM or PREM specifically developed for older people with frailty and emergency care needs.
