AbstractThe Dynamic Appraisal of Situational Aggression (DASA) provides a quick and systematic assessment of short-term violence risk. Risk assessment should be closely aligned to management and result in interventions aimed to reduce risk. The aim of this study was to investigate what interventions followed a moderate/high DASA score and whether they reduced risk. The impact of staff training was also assessed. The study was a retrospective analysis of health records within a medium secure hospital over 6 months. Data was gathered on tool adherence and interventions that were used to reduce risk following a moderate/high score. The change in DASA score following the intervention was recorded. There were 70 patients covering 8224 bed days. There were 24 occasions where a moderate score led to an intervention (n = 24/40%), and 26 occasions for a high score (n = 26/87%). A moderate score was mostly followed by no intervention (n = 35/59%), a high score was mostly followed by seclusion (n = 9/29%). The intervention that led to the largest reduction in DASA score was pro re nata medication following a moderate score and seclusion following a high score. The training of staff led to a reduction in tool adherence and increased intervention use. These results support the need for combining the DASA assessment with operationalised systems to link assessment with risk prevention to help reduce aggression and restrictive practices.
