Workplace violence is a common safety concern for hospital staff. The Behaviour Safety Risk Communication and Care Planning program identifies, manages and cares for patients at risk of exhibiting unsafe behaviours. This paper reports on a mixed-methods evaluation consisting of staff surveys, focus groups and open forums, screening audits, patient interviews and assessment of effectiveness measures at five hospital sites. Staff perceptions about safety risk imposed by a patient's behaviour significantly improved after this program was implemented. Opportunities exist to improve staff adherence to screening processes and communication with patients. This study provides insight for teams implementing similar interventions.
