Despite Overall Improvement In Surgical Outcomes Since 2000, Income-Related Disparities Persist

Abstract

Despite improvements in health care, disparities in care still exist and are widening for some health measures. This study examined postsurgical outcomes for patients from low-income areas as compared to outcomes for those from high-income areas in the United States from 2000 to 2009. We found that postsurgical outcomes improved in general, with significant decreases in nine of twelve mortality and patient safety measures and an increase in one measure. Patients from low-income areas had worse surgical outcomes than those from high-income areas for nine of twelve measures in both 2000 and 2009. The disparities in outcomes between low- and high-income groups did not change significantly for nine of the twelve measures. For the three measures that did change significantly, in only two of the cases was the change favorable for patients from low-income areas. These findings have implications for efforts to improve surgical outcomes and health policy and indicate the need for research on the cause of continued disparities in postsurgical outcomes.
