Objectives: To describe emergency department use by the elderly, to define problems associated with emergency care of the elderly, and to compare these results with those for younger adult patients., Design: Retrospective, controlled chart review., Setting: Six geographically distinct US hospital EDs., Participants: From each site, a stratified sample (approximately 7:3) of elderly (65 years or older) and nonelderly (21 to 64 years old) control patients treated during the same time period was used., Methods: Standardized review of ED records and billing charges. Comparisons of elderly and control patient groups using chi 2 analysis and Mann-Whitney U test (alpha = 0.05)., Results: Four hundred eighteen elderly patients and 175 nonelderly controls were entered into the study. The elderly were more likely to arrive by ambulance (35% versus 11%; P less than .00001). More elderly than controls presented with conditions of either high or intermediate urgency (78% versus 61%; P less than .0003). The elderly more frequently presented with comorbid diseases (94% versus 63%; P less than .00001). Other findings for the elderly included a longer mean stay in the ED (185 versus 155 minutes; P less than .003), higher laboratory (78% versus 53%; P less than .00001) and radiology (77% versus 52%; P less than .00001) test rates, higher mean overall care charges ($471 versus $344; P less than .00001), and an admission rate (47% versus 19%; P less than .00001) twice that of younger adults., Conclusion: Resource use and charges associated with emergency care are higher for the elderly than for younger patients. Increases in emergency resources and personnel or improvement in efficiency will be needed to maintain emergency care at present levels as the US population continues to grow and age.

Objectives: To compare group perceptions of reasons for emergency department care, ED use patterns, and the effect of illness on self-care ability for elderly and younger adult patients., Design: Patient survey., Setting: Six geographically distinct US hospital EDs., Participants: From each site, a stratified sample (approximately 7:3) of elderly (65 years and older) and nonelderly (21 to 64 years old) control ED patients treated during the same time period was contacted., Methods: Three hundred ninety-nine elderly patients and 172 adult controls were interviewed using a structured survey instrument. Groups were compared using chi 2 analysis and the Mann-Whitney U test., Results: Both the elderly and the control patients (49% versus 38%) commonly stated that the most important reason for coming to the ED was because they were "too sick to wait for an office visit." Of patients with a regular physician, both groups often were referred to the ED by their primary care provider (35% versus 26%). While the elderly had more visits to their primary care provider (3.3 versus 2.9 visits; P less than .00001), there was no difference in the number of ED visits (1.5 versus 1.6 visits) during the preceding six months. Of those released from the ED, more elderly noted deterioration in their ability to care for themselves as a result of their illness (21% versus 11%; P less than .03)., Conclusion: The elderly use the ED for reasons similar to those for younger adults. Often they feel too ill to wait for an office visit or are referred in by their primary care provider. Elderly patients more commonly have difficulty with self care after release home, and emergency physicians must plan accordingly.
