Failure to Rescue After Cardiac Surgery at Minority-Serving Hospitals: Room for Improvement

Despite living closer to high-performing centers, minority patients reportedly receive care at lower-quality hospitals. Investigating opportunities for improvement at minority-serving hospitals may help attenuate disparities in care among cardiothoracic surgery patients. We sought to investigate the relationship between hospital quality and failure to rescue (FTR).Over 451,000 cardiac surgery patients from 2000 to 2011 at minority-serving hospitals (MSHs) were identified from the Nationwide Inpatient Sample. After stratifying patients by hospital mortality quartile, outcomes at poorly performing MSHs were compared with those at high-performing MSHs. Propensity score matching was used for comparisons.Though patients at poorly performing centers were more likely Black, there were no significant differences in admission status (urgent vs elective), income, insurance, or risk before matching. There were no differences in comorbidities between low-performing and high-performing MSHs including chronic lung disease, coagulopathy, hypertension, and renal failure. While complications remained similar across mortality quartiles (29%, 32%, 31%, and 36%, respectively; P.0001), FTR increased in a stepwise manner (5.4%, 8.7%, 11.2%, and 15.5%, respectively; P.0001). The same was true after propensity score matching-FTR nearly tripled in the highest-mortality centers (14.4% vs 5.3%; P.0001), while complications only increased 1.2-fold from 31.1% to 36.7% (P = .0058). This finding persisted even when stratified by procedure type and by complication.Improving timely management of complications after cardiac surgery may serve as a promising opportunity for increasing quality of care at MSHs. When considering centralization of care in cardiac surgery, equal emphasis should be placed on collaboration between tertiary care centers and low-quality MSHs to mitigate disparities in care.
