Certified Nursing Assistants (CNAs) are the most frequently assaulted group in the United States1, with up to 70% of them reporting assault at work each month. This number is likely underestimated due to under-reporting. In nursing homes, assault may come from residents or a resident’s family member, another staff member, or even a member of the general public. Many studies report psychological issues such as, anger, frustration, self-blame and depression as a result of workplace assault, 2,3 as well as physical reactions such as fatigue, sleep problems and headache. 3, 4
One outcome of workplace assault that has not been explored much is the risk of musculoskeletal problems. A CPH-NEW study, ProCare (Promoting Mental and Physical Health of Caregivers), which evaluates the working conditions and health of nursing home workers, asked nurses and CNAs, "In the past three months, have you been hit, kicked, grabbed, shoved, pushed or scratched by a patient, patient’s visitor, or family member while you were at work?" Workers were also asked whether they had experienced pain or aching in various parts of the body during the preceding three months, and if so to rate its severity. 5
In a baseline survey, almost one-half of participating workers reported being assaulted during the past three months, with 26% reporting one to two assaults and 22% reporting three or more assaults. Importantly, the study also revealed a dose-response relationship for the prevalence of musculoskeletal pain (see figure below). Workers with low back pain also experienced more severe pain when they had been assaulted more often.
Prevalence of musculoskeletal pain, by frequency of recent physical assaults at work5
Follow-up at 12 and 24 months after the baseline survey revealed that repeated workplace assaults over time increased musculoskeletal pain occurrence. Workers experiencing assault in all three time periods had the highest rates of continuous pain, depression and pain interfering with work or sleep. 6 More CNA’s experienced these persistent assaults (34%) than did other clinical nursing staff, likely due to the high amount of time that they spend directly with residents.
Health care workers are already at considerable risk from musculoskeletal problems, due to their patient handling responsibilities. These problems may become more severe when stress due to violence (or other causes) slows the healing process. 3, 7 Over time, this could further impact worker productivity and quality of care due to staffing issues. 8
Preventing assault from occurring at work is an important focus of occupational safety in the healthcare sector. Training resources are available from NIOSH (see Resources, below); OSHA recommends several key elements for any assault prevention and control program:
