Evaluating progress in reducing workplace violence: trends in Washington State workers' compensation claims rates, 1997-2007.

OBJECTIVES

This study reports trends in the pattern of injuries related to workplace violence over the period 1997-2007. It tracks occupations and industries at elevated risk of workplace violence with a special focus on the persistently high claims rates among healthcare and social assistance workers.

METHODS

Industry and occupational incidence rates were calculated using workers' compensation and employment security data from Washington State.

RESULTS

Violence-related claims rates among certain Healthcare and Social Assistance industries remained particularly high. Incidents where workers were injured by clients or patients predominated. By contrast, claims rates in retail trade have fallen substantially.

CONCLUSIONS

Progress to reduce violence has been made in most of the highest hazard industries within the Healthcare and Social Assistance sector with the notable exception of psychiatric hospitals and facilities caring for the developmentally disabled. State legislation requiring healthcare workplaces to address hazards for workplace violence has had mixed results. Insufficient staffing, inadequate violence prevention training and sporadic management attention are seen as the key barriers to violence prevention in healthcare/social assistance workplaces.
