Abstract

Background: A key barrier to preventing workplace violence injury is the lack of methodology for prioritizing the allocation of limited prevention resources. The hazard risk matrix was used to categorize the probability and severity of violence in hospitals to enable prioritization of units for safety intervention.

Methods: Probability of violence was based on violence incidence rates; severity was based on lost time management claims for violence-related injuries. Cells of the hazard risk matrix were populated with hospital units categorized as low, medium, or high probability and severity. Hospital stakeholders reviewed the matrix after categorization to address the possible confounding of underreporting.

Results: Forty-one hospital units were categorized as medium or high on both severity and probability and were prioritized for forthcoming interventions. Probability and severity were highest in psychiatric care units.

Conclusions: This risk analysis tool may be useful for hospital administrators in prioritizing units for violence injury prevention efforts.

Keywords: hazard risk matrix; health care workers; injury; risk assessment; workplace violence.
