Although psychiatric diagnosis cannot effectively predict incidents except assaults, patient behavior patterns may be valuable for predicting the type of incident for which a patient might be vulnerable. When a patient, particularly a young male, becomes hyperactive, loud, and hostile, it is imperative to control the behavior with pharmacological on other means to avert potential violence. If a depressed patient, particularly a middle-aged woman, shows a significant level of anxiety and apprehension, it is important to observe the patient closely with continuing reassurance to prevent a potential suicide attempt. When a patient becomes markedly withdrawn, lethargic, and confused, a vigorous medical assessment is warranted to provide timely treatment for potentially life-threatening medical conditions. Thus careful monitoring of patients' behavior can direct staff members in the necessary precautions to take to prevent potential incidents.
