Improving Outcomes of Cardiac Surgery Through Cooperative Efforts: The Northern New England Experience

Abstract

Coronary artery bypass graft (CABG) surgery is an effective procedure for relieving angina. In 1987, the Health Care Financing Administration published surgeon-specific mortality rates, prompting the formation of the Northern New England Cardiovascular Disease Study Group (NNECDSG). This regional collaborative of all medical centers performing cardiovascular procedures in northern New England began collecting data concerning patient and disease characteristics and adverse outcomes in an effort to improve the care provided to their patients. An initial quality improvement effort resulted in a 24% reduction in in-hospital mortality. Subsequent efforts have involved the development and implementation of quality improvement initiatives to redesign care to reduce further a patient's risk of mortality and other morbidities. More recently, we have adopted this model to reduce a patient's risk of neurologic injury. In this study, we are intensively monitoring patients intraoperatively with transcranial Doppler and near infrared spectroscopy as well as collecting hemodynamic data, and are synchronizing this data with a video of the surgical site. The goal of the study is to identify the association between clinical strategies and the development of the precursors of neurologic injury and use a quality improvement approach to redesign care to reduce occurrence of these precursors.
