The Office of Statewide Health Planning and Development (OSHPD) released the “California Report on Coronary Artery Bypass Graft Surgery, 2009 Hospital Data,” showing that hospital operative mortality declined 34% since 2003, the first year of mandated public reporting for the 119 state-licensed hospitals that performed isolated coronary artery bypass graft (CABG) surgery during 2009. Performance ratings for hospitals are based on three risk-adjusted outcomes: operative mortality, operative stroke and, for the first time, hospital readmission. Additionally, utilization of the internal mammary artery during CABG surgery is used as a measurement of surgical quality. Hospital results for risk-adjusted mortality, risk-adjusted hospital readmission and internal mammary artery utilization are based only on 2009 data, while hospital results for risk-adjusted post-operative stroke are based on combined 2008 and 2009 data.
