Maintaining Quality in Lower Volume Cardiac Surgery: A Blueprint From a Military Program

Although there is a clear volume-outcome relationship in the field of cardiac surgery, the existence of high-performing programs with relatively low case volumes is well established. This report describes the programmatic and institutional processes in place at a lower volume cardiac surgery center in a US military hospital, which have been executed to optimally leverage available resources in the delivery of exemplary patient care. By implementing a highly collaborative practice, rigorous outcomes review, evidence-based standardized care pathways, consistent attending surgeon oversight for care delivery, careful case selection, and a mechanism for support from highly experienced outside cardiac surgeons, the cardiac surgery program at the authors' institution delivers care on par with its higher volume counterparts. A review of these practices and available supporting evidence may provide a model for other programs seeking success in this setting.
