From the abstract:
Objective: This study examined the relationship between changes in assault rates over time and the implementation of a workplace violence prevention (WVP) program in 138 Department of Veterans Affairs health care facilities.
Results: Training implementation was negatively associated with assault rates. Facilities with smaller bed sizes and without academic affiliates had lower assault rates.
Conclusions: Particular attention should be given to these dimensions because they may be associated with lower facility-level assault rates.
