ABSTRACT
A study of revenues generated and expenses incurred by 12 physician assistants (MEDEX) who had held salaried positions for at least one year was conducted to determine their financial impact on primary-care practices. Daily charge logs were used to make annual estimates of MEDEX-generated revenues. One method of estimating annual revenues produced a mean of $28,190 per year, and a second method yielded a figure of $30,210 per year. Financial statements were used in two different ways to estimate annual expenses related to the employment of the MEDEX. One procedure indicated average costs of employment were $15,900, and the other $20,100. Ten of the 12 practices in the study experienced substantial gains of estimated revenue over expenses ascribed to the activities of the MEDEX.
