To evaluate the relationship between ownership and use of ambulatory surgical centers (ASCs).From 1998 through 2002, discharges for procedures within genitourinary system were abstracted from Florida State Ambulatory Surgery Database. State-wide utilization rates surgery calculated by physician-level (using an empirically-derived, externally-validated method) financial incentives. A surgeon-level Poisson regression model was fit to compare year, ownership, their interaction.Rates increased 607 per 100,000 in 702 2002 (P < 0.01 trend). Although at hospital only slightly (0.9%), those ASC up 53% 0.01). Physician associated with this greater as new owners 9 94 0.01) first full year owners. In proportion a owner's surgeries comprising financially lucrative 61% compared 50% preceding 0.01).Physician is increasing ASCs, although extent which attributable previously unmet demand unclear. However, seem alter procedure mix after establishing include share procedures.
