Objective: To determine the contributions of veterinarians and support staff to revenue and veterinarian productivity (ie, number of patients seen/full-time-equivalent veterinarian/wk) in private mixed and companion animal practices in the US and identify staff-to-veterinarian labor ratios (SVLRs) that maximized these 2 practice outputs.
Sample: 409 owners of mixed and companion animal practices who participated in the 2020 AVMA Practice Owner Survey.
Procedures: Data regarding owner demographics, practice characteristics, labor (defined as mean total hours worked/wk), and gross revenue in 2019 were obtained from participating practices. Multivariable ordinary least-squares regression was used to identify factors associated with revenue and productivity as well as the SVLRs at which revenue and productivity were maximized.
Results: For each 10% increase in total veterinarian hours worked per week, revenue increased by a mean of approximately 9%. A 1-unit increase in total number of technician hours used to support 1 hour of veterinarian work was associated with a 20.5% increase in revenue but with no change in productivity. The same increase in total number of nonmedical staff hours was associated with a 17.0% increase in revenue and 14.4% increase in productivity. In terms of revenue, the optimal SVLRs for veterinary technicians and nonmedical staff were 9:1 and 8:1, respectively. In terms of productivity, the optimal SVLR for nonmedical staff was 10:1.
Clinical relevance: Findings confirmed the important role of nonveterinarian staff in revenue and veterinarian productivity in mixed animal and companion animal practices and may be useful for making evidence-based staffing decisions.
