Emergency room evaluation and recommendations for older emergency department users: results of the ER² experimental...

The study aims to examine whether the use of "emergency room evaluation and recommendations" (ER²) tool in daily ED practice reduces the length of stay in ED and hospital, and hospital admission in older patients visiting ED on stretcher.

A total of 3931 older patients visiting ED of the Jewish General Hospital (Montreal, Quebec, Canada) on stretcher were recruited in this non-randomized, pre-post intervention, single arm, prospective and longitudinal open-label trial. ED staff and patients were blinded of the ER² score and patients received usual ED care over the observational phase, whereas ED staff were informed about the ER² score and patients had usual care plus interventions based on tailor-made geriatric recommendations during the interventional phase. The length of stay in ED and in hospital, and hospital admission were the outcomes.

The ER² recommendations were associated with increased length of stay in ED (β = 2.94 with P ≤ 0.001) and decreased length of stay in hospital (β = - 2.07 with P = 0.011). No effect was found for hospital admission (Odd Ratio (OR) = 0.92 with P = 0.182).

Emergency room evaluation and recommendations (ER²) tool had mixed effects. Shorter hospital stay has been reported for older ED users hospitalized, but increased ED stay and no effects on hospital admission were found.
