Evaluation of risk and protective factors for work-related bite injuries to veterinary technicians certified in Minnesota

摘要

Objective—To identify risk and protective factors for work-related bite injuries among veterinary technicians certified in Minnesota.Design—Nested case-control study.Sample—868 certified veterinary technicians (CVTs).Procedures—A questionnaire wasmailed to CVTs who previously participated in a survey regarding work-related injuries and did (cases; 301 surveys sent) or did not (controls; 567) report qualifying work-related animal bite injuries in the preceding 12 months. Descriptive statistics were summarized. Demographic and work-related variables for the month preceding the bite injury (for cases) or a randomly selected month (controls) were assessed with univariate analysis (489 CVTs) and multivariate analysis of a subset of 337 CVTs who worked in small or mixed mostly small animal facilities.Results—Responses were received from 176 case and 313 control CVTs. For the subset of 337 CVTs, risk of bite injury was higher for those < 25 years of age (OR, 3.82; 95% confidence interval [CI], 1.84 to 7.94) than for those > 35 years of age, for thosewho had worked < 5 years (OR, 3.24; 95% CI, 1.63 to 6.45) versus > 10 years in any veterinary facility, and for those who handled > 5 species/d (OR, 1.99; 95% CI, 1.06 to 3.74) versus < 3 species/d. Risk was lower for CVTs who handled < 10 versus > 20 animals/d (OR, 0.23; 95% CI, 0.08 to 0.71).Conclusions and Clinical Relevance—Several work-related factors were associated with the risk of work-related bite injury to CVTs. These findings may serve as a basis for development of intervention efforts and future research regarding work-related injuries among veterinary staff.
