1 The Role of Insurance in Providing Access to Cardiac Care in Maryland Samuel L. Brown, Ph.D. University of Baltimore College of Public Affairs
2 Heart Disease Heart Disease is the leading cause of death in Baltimore City, the State of Maryland, and in the nation. Coronary Heart Disease (CHD) is the number one killer in America affecting more than 15 million, and responsible for around half of deaths for all diseases of the heart. In the past decade, mortality rate for heart disease have decreased, however disparities remain.
3 State of Maryland Black heart disease mortality rate was reduced by 28.8%. White heart disease mortality rate was reduced by 28.8% as well. The mortality rate difference between the groups was reduced by 29.1%
4 Research Questions Are sociodemographic characteristics likely predictors for undergoing invasive cardiac procedures for CHD hospitalized patients living in Maryland? What is the impact of dual health coverage (Medicare and Medicaid) in reducing the gap for treating CHD?
5 Hypotheses There will be racial and gender differences in the use of treatments for CHD by insurance status. Medicare/Medicaid patients are more likely to be treated for cardiac care compared to Medicaid and privately insured patients by race, gender, and socioeconomic status.

17 Findings Based on the discharge data, white men with AMI are more likely to receive access to care compared to women and minorities. African-American women are at high risk for not receiving treatment for CHD in comparison to other groups. Medicare and Medicaid patients are just as likely to be treated as privately insured patients.
18 Conclusions There were clear differences in access across Maryland Counties. Even with controls for age, gender, co morbidities, blood pressure, and diabetes, there is little difference in access between Medicare and commercial fee for service insurers. It appears that racial differences in insurance coverage does not explain much of the racial difference in access to care. Large gaps in access across all insurance comparisons remain insurance matters, but not very much.
19 Conclusion More extensive research is imperative in understanding the disparities in terms of access and outcomes especially with the implementation of health care reform that will expand health coverage for more Americans. It remains to be seen whether being insured guarantees positive health outcomes.
