Discussing the threat of aggression is not always at the forefront in ambulatory care providers. A structured risk analysis model for ambulatory emergency psychiatry is currently not available, while aggression does occur regularly.

The aim of this study is to evaluate the added value of a risk analysis model and implement the best available model in emergency outpatient practice.

The study design is a mixed method model. Semi-structured questionnaires were administered by nurses and psychiatrists. A benchmark study took place at an outpatient emergency service in South Netherlands. A literature search was performed using PubMed and CINAHL for the period 2000–2014.

From this research, we found a discrepancy between the perception and the actual occurred aggression. Care workers often do not discuss aggression related issues, however, case studies show that aggression does occur frequently. In literature studies we have found several risk assessment models, most of which are used within the inpatient psychiatry.

To avert aggression incidents and prevent recurrence, it is important to maintain a solid risk analysis model. Introducing a checklist risk crisis service (CRC) can promote a critical reflection on the threat of aggression and bring awareness on the theme of aggression. Implementation of a CRC in daily practice can be of great value.
