Abstract
Objective:
This study examined prospectively the effect of workplace violence on musculoskeletal symptoms among nursing home workers.
Background:
Previously we reported a cross-sectional relationship between physical assaults at work and musculoskeletal pain. This follow-up provides stronger evidence of the effect of workplace violence on musculoskeletal outcomes within the same workforce over two years.
Method:
Nursing home workers who responded to three consecutive annual surveys formed the study cohort (
Results:
Every fourth nursing home worker, and 34% of nursing aides, reported persistent workplace assault over the 2 years. Among respondents assaulted frequently, two thirds experienced moderate to extreme musculoskeletal pain, and more than 50% had pain interfering with work and/or sleep. Baseline exposure to assault predicted pain outcomes 1 year later. Repeated exposure was associated with a linear increase over 2 years in the risks of pain intensity, interference with work, and interference with sleep; co-occurring pain and depression had an adjusted PR of 3.6 (95% CI = 1.7–7.9).
Conclusion:
Workplace assault, especially when repeated over time, increases the risk of pain that may jeopardize workers’ ability to remain employed.
Application:
More effective assault prevention would protect and support the workforce needed to care for our increasing elderly and disabled population.
