Older adults in the emergency department: a systematic review of patterns of use, adverse outcomes, and effectiveness of interventions
Abstract
Study objective We sought to synthesize the literature on patterns of use of emergency services among older adults, risk factors associated with adverse health outcomes, and effectiveness of intervention strategies targeting this population.Methods Relevant articles were identified by means of an English-language search of MEDLINE, HealthSTAR, CINAHL, Current Contents, and Cochrane Library databases from January 1985 to January 2001. This search was supplemented with literature from reference sections of the retrieved publications. A qualitative approach was used to synthesize the literature.Results Compared with younger persons, older adults use emergency services at a higher rate, their visits have a greater level of urgency, they have longer stays in the emergency department, they are more likely to be admitted or to have repeat ED visits, and they experience higher rates of adverse health outcomes after discharge. The risk factors commonly associated with the negative outcomes are age, functional impairment, recent hospitalization or ED use, living alone, and lack of social support. Comprehensive geriatric screening and coordinated discharge planning initiatives designed to improve clinical outcomes in older emergency patients have provided inconclusive results.Conclusion Older ED patients have distinct patterns of service use and care needs. The current disease-oriented and episodic models of emergency care do not adequately respond to the complex care needs of frail older patients. More research is needed to determine the effectiveness of screening and intervention strategies targeting at-risk older ED patients.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
