Interface between residential aged care facilities and a teaching hospital emergency department in Western Australia

To estimate the appropriateness of emergency department (ED) presentations by people aged>or=65 years living in residential care facilities.

Retrospective cohort study of older residents of residential care facilities who presented to the ED of the Royal Perth Hospital, Western Australia, between January and June 2002. Data were reviewed by an expert clinical panel.

Appropriateness of ED presentation, presenting complaint, involvement of a general practitioner/locum doctor prior to transfer, proportion of patients admitted to hospital from the ED, survival to discharge.

541 residents aged>or=65 years were transferred by ambulance to the ED, comprising 8.3% of all ED presentations of people in this age group. The mean age of the study cohort was 83.7 years (SD, 7.0 years), of which 68% were women. Of the 541 presentations, 326 (60%) resulted in hospital admission, and of these, 276 (85%) survived to hospital discharge. Musculoskeletal disorders accounted for 25% of all presentations, and 22% were falls-related; pneumonia (11% of presentations) was the single largest presenting complaint. ED attendance was deemed "inappropriate" for 71/541 cases (13.1%; 95% CI, 10.5%-16.2%); in only 25% of ED presentations was a GP/locum doctor involved prior to transfer.

The majority of ED presentations by aged care residents were considered to be appropriate, but there was scope for improvement in coordinating care between the hospital ED and residential care institutions.
