P-614 Multi-Method Assessment of Ergonomic Risks to Veterinary Technicians at a Small-Animal Clinic

Introduction Veterinary technicians in small-animal clinics are often exposed to activities associated with work-related musculoskeletal disorders (WMSDs), but the available research is limited. This multi-method case study identifies prevalent tasks with ergonomic hazards and defines the associated risk levels. Potential interventions are discussed. Methods Nine technicians participated in assessing symptoms and identifying tasks with ergonomic risk factors. A modified NORDIC questionnaire was administered to determine WMSD discomfort. A focus group identified activities with ergonomic risk factors. The jobs with high-risk factors were further evaluated using the Rapid Entire Body Assessment (REBA). Results All participants experienced musculoskeletal discomfort in at least five body regions. They reported being unable to perform work over the last 12 months due to WMSDs on shoulders, ankles, and feet 33% (n=3), neck and lower back 22% (n=2), and wrists, hands, hips, thighs, and knees 11% (n=1). One respondent reported no discomfort over the last seven days, while eight indicated discomfort in three or more body areas. Three tasks were chosen for REBA analysis. Restraining and handling animals had a high-risk REBA score (ranging from 8 to 10). Sedation/recovery had a low to medium-risk REBA score (3 to 5). Dental procedure recovery had a low to very high-risk REBA score (ranging from 2 to 11). Discussion The findings indicate that most veterinary technicians experience musculoskeletal discomfort and are exposed to significant WMSD risk levels when performing everyday tasks. Conclusion This assessment produced several administrative and engineering controls to reduce the risk of WMSDs in the selected tasks.
