[The situation of emergency psychiatry in Germany].
The impact of psychiatric emergencies for the care of patients in preclinical emergency medicine, in emergency departments and in psychiatric hospitals has been underestimated for a long time. There is still insufficient knowledge and a need for further research. There are, however, sufficient reasons to assume that annually approximately 500,000 patients with a psychiatric emergency receive treatment from a preclinical emergency physician and another 1.5 million in emergency departments in Germany. Further, approximately 500,000 patients are admitted to psychiatric hospitals as an emergency. The most frequent reasons are intoxication, agitation, aggressiveness and suicidal ideation, posing a threat of self-harm to the patient or to other persons and evoking other life-threatening conditions. Emergency psychiatry also plays a role in collective injuries, such as mass disasters, catastrophes and rampage situations. There is some evidence that the number of psychiatric emergencies is increasing. Reasons are, among others, changes in the services provided for inpatient and outpatient treatment, a reduction in stabilizing psychosocial factors and a general increase in the utilization of emergency healthcare services.
