- To determine how regionalization of facilities for coronary artery bypass surgery (CABS) affects geographic access to CABS and surgical outcomes.
- Computedzed hospital discharge records were used to measure hospital CABS volume and in-hospital post-CABS mortality rates.
Relationships between surgical volume and age-and sex-adjusted mortality rates were compared using khi2 tests.
Small-area analysis of the association between CABS rates and distances to nearest CABS hospital was performed using multivariate linear regression methods.
- In New York and Canada, approximately 60% of all CABS operations took place in hospitals performing 500 or more CABS operations per year, compared with only 26% in California.
The highest mortality rates were found among California hospitals performing fewer than 100 CABS operations per year.
The percentage of the population residing within 25 miles of a CABS hospital was 91% in California, 82% in New York, and less than 60% in Canada.
Eliminating very low-volume CABS hospitals in California would increase travel distances to a CABS hospital only slightly for a small number of residents.
- Regionalization of CABS facilities in New York and Canada largely avoids the problem of low-volume outlier hospitals with high postoperative mortality rates found in California.
New York has avoided the redundancy of facilities that exists in California while still providing res.
