Chief complaint: Homicidal. Assessing violence risk

Author and Disclosure Information

In that case, the most important step will be to carry out your duty to warn/protect others prior to Mr. F’s discharge. Most states either require or permit mental health professionals to take reasonable steps to protect victims from violence when certain conditions are present, such as an explicit threat or identifiable victim (see Related Resources).

Once dynamic risk factors have been addressed, and duty to warn/protect is carried out, if there is no further clinical indication for hospitalization, it would be appropriate to discharge Mr. F. Continued homicidal threats stemming from antisocial personality traits, in the absence of a treatable mental illness (or other modifiable risk factors for violence that can be actively addressed), is not a reason for continued hospitalization. It may be useful to obtain a second opinion from a colleague in such scenarios. A second opinion may offer additional risk management ideas. In the event of a bad outcome, this will also help to show that the decision to discharge the patient was not taken lightly.

The psychiatrist should document a thoughtful risk assessment, the strategies that were implemented to reduce risk, the details of the warning, and the reasoning why continued hospitalization was not indicated (Table 3).

CASE CONTINUED

Decision to discharge

In Mr. F’s case, the treating psychiatrist determined that Mr. F’s risk of violence toward Ms. S was moderate. The psychiatrist identified several static risk factors for violence that raised Mr. F’s risk, but also noted that Mr. F’s threats were likely a manipulative effort to prolong his hospital stay. The psychiatrist carried out his duty to protect by notifying police and Ms. S of the nature of the threat prior to Mr. F’s discharge. The unit social worker helped Mr. F schedule an intake appointment for a substance use disorder treatment facility. Mr. F ultimately stated that he no longer experienced homicidal ideas once a bed was secured for him in a substance use treatment program. The psychiatrist carefully documented Mr. F’s risk assessment and the reasons why Mr. F’s risk would not be significantly altered by further inpatient hospitalization. Mr. F was discharged, and Ms. S remained unharmed.
