Abstract
Objective: To assess the occurrence, type, and burden of adverse clinical events (ACE) among residents of chronic facilities. An ACE is any acute or subacute change in health status suggesting acute or subacute illness.Design: Survey with face‐to‐face functional assessment and 3‐month retrospective chart review.Study Population: One hundred six continuing‐care residents with a minimum length of stay of 4 months at an Italian chronic care facility.Measurements: Functional assessment and chart review‐based classification of ACE burden on care management according to a clinical‐functional Severity Rating Scale.Main Results: Functional dependence, dementia and concurrent clinical problems were common. Two hundred seventy‐three ACEs were detected. Eighty‐nine percent of residents experienced at least one ACE. Only 21% of ACEs could be managed by simple medical intervention and monitoring within 1 day; in 23% there was need for more complex care management; 7% of the latter ACEs resulted in residual (new) functional impairment. Cardiovascular and gastrointestinal systems were most commonly involved in ACEs. Neurological ACEs were the most frequent category leading to new functional impairment (22%). ACE occurrence/burden was higher in male residents (P < 0.01) and strongly associated with the number of concurrent medical problems (P < 0.001). Neither cognitive nor functional dependence levels were related to ACE occurrence.Conclusions: This description of the burden on care management resulting from acute and subacute changes in clinical and functional status of chronic patients emphasizes the continuing and unpredictable nature of medical attention required in a nursing home or chronic care facility. ACEs occur far more frequently among the elderly than is generally recognized. Thus a high level of medical and nursing skill is necessary in chronic care facilities.
