Background: In 2003, a satellite cardiac surgery program (SAT) was implemented at an affiliated community hospital located in an area historically served by an academic medical center (AMC). This study assessed the financial consequences and the changes in case-mix that occurred at the AMC after SAT implementation.

Methods: From June 2002 through December 2005, 4593 adult patients underwent cardiac operations at the AMC. Excluded were 400 patients operated on during the 4-month transition period after SAT implementation and 1210 patients living more than 35 miles from the AMC. Multivariable regression was used to compare changes in case-mix and propensity-score adjusted costs for AMC patients referred from SAT area (N_{before/after =} 328/291) vs other patients (N_{before/after =} 897/1467).

Results: The SAT area referral rate decreased by 55%. Compared with other patients, AMC patients referred from the SAT area showed a greater increase in age in the second period (p = 0.013). The nursing workload and adjusted mean costs increased more for patients from the SAT area (p = 0.015 and 0.014, respectively). The hospital margin decreased in the second period for both referral areas (p < 0.001). For the patient subgroup undergoing coronary artery bypass grafting, this hospital margin decrease was greater for SAT area patients (p = 0.017).

Conclusions: After implementation of SAT program, fewer patients of lower complexity came to the AMC from the SAT area, and there was a significant increase in nursing workload and costs. During this interval, hospital margin for cardiac operations decreased from both referral areas but decreased significantly more for coronary artery bypass graft patients from the SAT area.
