Implementation of a violence risk assessment tool on a safety-net inpatient psychiatry unit

Screening for Behavioral Health Patient Aggression in Emergency Departments to Reduce Workplace Violence

INTRODUCTION

Patient violence in health care facilities occurs daily. Structured risk assessments, when regularly completed, have been effective in prompting interventions to reduce aggression in Behavioral Health (BH) settings.

METHODS

This quasi-experimental study evaluated the effectiveness of the Dynamic Appraisal of Situational Aggression - Inpatient Version (DASA) validated screening tool to reduce aggressive outbursts in an emergency department (ED) setting with BH patients awaiting transfer to a psychiatric facility. The tool was used in 4 non-psychiatric EDs from a large health care system. Chart audits were completed to record initial patient DASA scores observed at triage and at subsequent intervals during the ED encounter. ED staff documented interventions used for patients. Inclusion criteria included adults 21 years and older following a telepsychiatry consultation with a recommendation for BH inpatient admission. Pre-/post-implementation aggressive events were collected to assess ED DASA use. DASA scores from BH ED patients were examined to increase understanding of patient utilization. Staff workplace safety was examined to compare staff safety perception pre- and post-DASA implementation.

RESULTS

Violent events were reported statistically significantly higher post-DASA implementation. There was an increased risk of elevated DASA scores for specific diagnoses and genders. An increased awareness of the importance of reporting workplace violence improved documentation.

DISCUSSION

Using an evidence-based screening tool helped identify BH patients with behaviors associated with aggressive ED events. Proactive use of interventions, including use of Comfort Cart items, de-escalation, and prescribed medications, can positively influence reduction of risk from aggressive behaviors within BH patient populations in EDs.

Risk Assessment in Mental Health Practice: An Integrative Review

Although risk assessment in mental health practice can influence and measure treatment outcomes and level of care provision, risk assessment practices are not standardised and different screening tools are used. The aim of this integrative review was to review the literature on risk assessment in mental health practice to promote evidence-based care. Electronic databases were searched for articles available in English and published from 2013 to 2019. The findings from 12 articles evaluated the evidence for risk assessment tools utilised and discussed the justification, barriers and enabling factors for risk assessment. Lastly, recommendations were made to improve risk assessment.
