Chief complaint: Homicidal. Assessing violence risk

Author and Disclosure Information

Mr. F’s answers may suggest the possibility of a hidden agenda. Some patients express homicidal thoughts in order to stay in the hospital. If Mr. F expresses threats that are contingent on discharge and declines to engage in problem-solving discussions, this would cast doubt on the genuineness of his threat. However, doubt about the genuineness of the threat alone is not sufficient to simply discharge Mr. F. Assessment of his intent needs to be considered with other relevant risk factors, risk reduction strategies, and any Tarasoff duties that may apply.

In addition to risk factors, consider mitigating factors. For example, does Mr. F express concern over prison time as a reason to not engage in violence? It would be more ominous if Mr. F says that he does not care if he goes to prison because life is lousy being homeless and unemployed. At this point, an estimation can be made regarding whether Mr. F is a low-, moderate-, or high-risk of violence.

The next step is to organize Mr. F’s risk factors into static (historical) and dynamic (subject to intervention) factors. This will be helpful in formulating a strategy to manage risk because continued hospitalization can only address dynamic risk factors. Often in these cases, the static risk factors are far more numerous than the dynamic risk factors.

Once the data are collected and organized, the final step is to devise a risk management strategy. Some interventions, such as substance use treatment, will be straightforward. A mood-stabilizing medication could be considered, if clinically appropriate, to help reduce aggression and irritability.31 Efforts should be made to eliminate Mr. F’s access to firearms; however, in this case, it sounds unlikely that he will cooperate with those efforts. Ultimately, you may find yourself with a list of risk factors that are unlikely to be altered with further hospitalization, particularly if Mr. F’s homicidal thoughts and intent are due to antisocial personality traits.
