Impact of physician income source on productivity.

Based on data from the 2004 National Physician Survey, physicians whose primary payment method was fee-for-service saw more patients per week than physicians remunerated by other methods, including salary or blended payments. This result did not change when examined according to specialty or specialty grouping (Table 1), physician age (Table 2) Family physicians versus specialists, type of practice (office-based versus hospital-based; data not shown), or practice setting (urban versus rural; data not shown). Overall, fee-for-service (FFS) physicians saw approximately twice the number of patients per week as salaried physicians. These data provide convincing evidence that FFS physicians see substantially more patients.
