Abstract
Background
Pre-clinical psychiatric emergencies are generally treated by emergency medical staff. The subsequent clinical treatment is often conditioned by interaction problems between emergency medical staff and psychiatric clinical staff.

Objectives
To identify problems affecting interaction between emergency medical and psychiatric care of mentally ill patients and pinpoint aspects of optimized emergency care.

Methods
To shed light on the interaction problems an anonymous, questionnaire-based, nonrepresentative survey of 98 emergency physicians (EM) and 104 psychiatrists (PS) practicing in acute psychiatry was conducted between March 1, 2021 and October 1, 2021.

Results
The chi-square test for multiple response sets revealed consistently significant differences (p < 0.001) between EM and PS with respect to the questions analyzed. Approximately 36% of EM reported not to be adequately qualified to handle psychiatric emergencies (p = 0.0001), while around 50% of respondents were neutral in their assessment in how to deal with psychiatric emergencies. 80% of EM reported a negative interaction (rejection of patients) with PS when referring a psychiatric emergency patient to the acute psychiatric unit. The most common reasons for refusal were intoxication (EM: 78.8%, PS: 88.2%), emergency physician therapy (EM: 53.8%, PS: 63.5%), and not resident in the catchment area of the hospital (EM 68.8%, PS: 48.2%). In the casuistry presented, most respondents would choose “talk down” for de-escalation (EM: 92.1%, PS: 91.3%). With respect to drug therapy, benzodiazepine is the drug of choice (EM: 70.4%, PS: 78.8%). More EM would choose an intravenously (i.v.) or a Mucosal Atomization Device (MAD) administration as an alternative to oral medication (i.v.: EM: 38.8%, PS: 3.8%, p = 0.001, MAD: EM: 36.7%, PS: 10.6%, p = 0.006). Significantly more EM would seek phone contact with the acute psychiatric hospital (EM: 84.7%, PS: 52.9%, p = 0.0107). A psychiatric emergency plan was considered useful in this context by more than 90% of respondents. The need for further training for EM with regard to treating psychiatric clinical syndromes was considered important by all respondents. In particular, the topics of “psychogenic seizure,“ “intoxication,“ and “legal aspects of psychiatric emergencies” were considered important (Mann-Whitney U test, p < 0.001).

Conclusion
The interaction-related problems identified in the emergency medical care of pre-clinical psychiatric patients relate to non-modifiable, structural problems, such as insufficient admission capacity and non-existent or inadequate monitoring capabilities in acute psychiatric hospitals. However, factors such as the education and training of EM and communication between EM and PS can be improved. Developing personalized emergency care plans for psychiatric patients could help to optimize their care.
