Toward prevention of behavioral emergencies in a general hospital insights from a one-year series.

Background: Behavioral emergencies endanger hospital staff and patients. The objective of this study was to identify patient characteristics that could be used to predict and prevent these incidents.

Methods: We analyzed a one-year consecutive series of behavioral emergencies that triggered the rapid response team at a general hospital, comparing study patients with controls who did not trigger a rapid response. Standard parametric or nonparametric tests, as appropriate, were used to compare the 2 groups in univariate analyses, and multivariable logistic regression analysis was used to identify the best combination of variables for stratifying the risk of such an event.

Results: There were 109 behavioral emergencies involving 83 patients. Comparison of patients who did (n = 83) or did not (n = 22,849) trigger a rapid response revealed marked differences between the two groups with respect to age, sex, and the prevalence of psychiatric comorbidities and various conditions that can diminish cognitive function. Substance use disorder was the most frequent principal diagnosis in the study group, accounting for 10.8% (9/83) of study patients vs. 0.6% (132/22849) of controls (p < 0.0001). The presence of a condition that can impair cognition (substance intoxication and withdrawal, epilepsy, cerebrovascular disease, traumatic brain injury, delirium, dementia) was associated with a 13-fold increase in the risk of a behavioral disturbance (95% CI, 8 to 22-fold).

Conclusions: Brief cognitive assessment of patients susceptible to cognitive impairment, along with diligent prophylaxis and management of substance withdrawal and delirium, may facilitate prevention of behavioral emergencies.
