Musculoskeletal pain and reported workplace assault: a prospective study of clinical staff in nursing homes

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 (n = 344). The outcomes were any musculoskeletal pain, widespread pain, pain intensity, pain interference with work and sleep, and co-occurring pain with depression. The main predictor was self-reported physical assault at work during the 3 months preceding each survey. Prevalence ratios (PRs) were assessed with log-binomial regression, adjusting for other workplace and individual factors.

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.

Work-related determinants of multi-site musculoskeletal pain among employees in the health care sector

BACKGROUND

Work-related musculoskeletal pain is a major occupational problem. Those with pain in multiple sites usually report worse health outcomes than those with pain in one site.

OBJECTIVE

This study explored prevalence and associated predictors of multi-site pain in health care sector employees.

METHOD

Survey responses from 1348 health care sector employees across three organisations (37% response rate) collected data on job satisfaction, work life balance, psychosocial and physical hazards, general health and work ability. Musculoskeletal discomfort was measured across 5 body regions with pain in ≥ 2 sites defined as multi-site pain. Generalized linear models were used to identify relationships between work-related factors and multi-site pain.

RESULTS

Over 52% of the employees reported pain in multiple body sites and 19% reported pain in one site. Poor work life balance (PRR = 2.33, 95% CI = 1.06-5.14). physical (PRR = 7.58, 95% CI = 4.89-11.77) and psychosocial (PRR = 1.59, 95% CI = 1.00-2.57) hazard variables were related to multi-site pain (after controlling for age, gender, health and work ability. Older employees and females were more likely to report multi-site pain.

CONCLUSION

Effective risk management of work related multi-site pain must include identification and control of psychosocial and physical hazards.
