Although disparities exist in health care, those gaps are small compared with the health care everyone receives and what they should be receiving, according to a report from the RAND Corporation. “Differences exist. But they pale in comparison to the chasm between where we are today and where we should be,” said Dr. Steven M. Asch of the University of California, Los Angeles, the study's lead author. The study assessed preventive services and care for 30 acute and chronic conditions that constitute the leading causes of death and disability. Overall, participants received about 55% of recommended care, despite the fact that the recommendations for the conditions involved were widely known and accepted.
