1 WILL EQUITY BE ACHIEVED THROUGH HEALTH CARE REFORM? John Z. Ayanian, MD, MPP Brigham and Women s Hospital Harvard Medical School Harvard School of Public Health BWH Patient-Centered Outcomes Seminar April 23, 2013

2 OBJECTIVES 1) Introduce conceptual framework for understanding health care disparities 2) Highlight key research & reports on disparities in health care 3) Consider policy approaches for achieving equity through health care reform under ACA: Insurance coverage Coordination of care Performance measurement & feedback

3 CROSSING THE QUALITY CHASM REPORT Equitable care is one of 6 core aims for improving health-care systems *Along with effective, efficient, timely, safe & patient-centered care Institute of Medicine, 2001

4 DIFFERENCES, DISPARITIES & DISCRIMINATION Difference Clinical Need, Appropriateness, Patient Preferences Healthcare Systems & Legal / Regulatory Systems Discrimination: Bias, Stereotyping, & Uncertainty Disparity Institute of Medicine, 2003

5 Conceptual Model for Health Care Disparities Patient Factors: Race/ethnicity, age, insurance, SES Community Factors Quality of Care Received Outcomes Physician, Hospital & Health System Factors Ayanian World J Surg 2008

6 1) Describing the problem 2) Understanding mediators & outcomes HISTORY OF RESEARCH ON HEALTH CARE DISPARITIES ) Determining? effective interventions Ayanian World J Surg 2008

7 THE CAST Simulated Patients with Chest Pain in a Video About Referral for Cardiac Catheterization Schulman et al. N Engl J Med 1999

8 HEADLINES ABC Nightline A Recent Study Shows that Doctors Diagnose Black and White Patients Differently Los Angeles Times Heart Study Points to Race, Sex Bias New York Times Doctor Bias May Affect Heart Care, Study Finds

9 Pittsburgh Post-Gazette

10 Setting the Context Minority Americans less likely than whites to get many effective medical & surgical services Increasing attention to reasons for differences: Patient preferences? Clinical factors? Socioeconomic factors? Communication and trust? Physician bias? Fragmented systems of care? Research vital for clinical & policy solutions

13 UNEQUAL TREATMENT REPORT Racial & ethnic disparities in care associated with worse outcomes, thus unacceptable Disparities reflect broader inequality & discrimination in American society Institute of Medicine, 2003

14 Insurance Coverage

15 The Diagnosis of Exclusion Unfortunately you have what The New Yorker we call no insurance.

16 Jim Waterhouse s Story * Diagnoses: hypertension, diabetes, heart disease, sleep apnea While uninsured in his early 60 s: Reduced visits to primary physician and cardiologist Reduced glucose monitoring Ignored worsening dyspnea Discontinued CPAP for sleep apnea Deferred colonoscopy for new anemia Complications: Delayed visit to primary MD led to $46,000 admission * Hayes et al. Too Sick to Work, Too Soon for Medicare, Commonwealth Fund 2007

17 I tried to put off medical care until I became eligible for Medicare, which complicated my condition. --Jim Waterhouse, after gaining Medicare coverage

18 Rates of Uninsurance by Race & Ethnicity US Non-Elderly Population, 2011 Uninsured Rate (Percent) General population under age Non- Hispanic White 18.0 Asian American and Pacific Islander 21.0 African American 27.0 American Indian and Alaska Native 32.0 Hispanic Current Population Survey, 2012

20 Nonwhite White Difference in HbA1c (%) 1.6 Glucose Control for Diabetes US Black & Hispanic vs. White Adults NHANES, Difference from pre-65: - 0.7% (P<0.001) Age McWilliams, Meara, Zaslavsky & Ayanian. Ann Intern Med 2009

21 Worse Health Score Better Trends in Health of Adults with Cardiovascular Disease or Diabetes Differential Change in Trend: (P=0.006) Age Uninsured Before 65 Continuously Insured Before 65 Expected Trend McWilliams, Meara, Zaslavsky & Ayanian. JAMA 2007

22 Benefits & Challenges of Health Care Reform 16 million low-income adults newly eligible for Medicaid 16 million middle-income adults newly eligible for private coverage through employers or insurance exchanges ************************************************************** How many states will expand Medicaid? How quickly will people be enrolled in new coverage? Will they have access to effective primary & specialty care, medications, and preventive services? Insurance coverage alone won t eliminate disparities!

24 Coordination of Care

25 PATIENT RATINGS OF OVERALL CANCER CARE AS EXCELLENT / VERY GOOD Northern California, Percent White Black Hispanic Asian English Non- English Ayanian et al. J Clin Oncol 2005 Coordination of care strongest factor in overall quality ratings in all groups Race/Ethnicity Language

26 HOW DO FRAGMENTED SYSTEMS OF CARE CONTRIBUTE TO DISPARITIES? System deficits affect all segments of society, but especially non-white patients Disadvantaged patients fall through the cracks in complex systems of care Small disparities in multi-step processes create moderate to large disparities overall Disparities arise even when providers well intentioned

27 PATIENT NAVIGATORS Intuitively appealing to improve coordination of care Promising model for community engagement and serving disadvantaged communities Rigorous evaluation will be essential to build support and secure funding Promising results for cancer screening navigators in Cambridge Health Alliance and New York City

29 New York City Department of Health public service announcement

30 Health Systems & Communities Partnering to Promote Screening & Eliminate Disparities New York City, In my career, 3 things have surprised me: how quickly TB cases came down in NYC, how quickly tobacco use came down in NYC, and how quickly colon cancer screening went up in NYC, Dr. Frieden said. Even more surprising is the closing of the race and ethnicity gap White Black Hispanic White Black Hispanic New York Times, 2008

32 Performance Measurement

33 ADDRESSING DISPARITIES THROUGH QUALITY PERFORMANCE MEASURES Disparities are quality problem Current data inadequate Fiscella et al. JAMA 2000 Stratify quality measures by race/ethnicity & socioeconomic position

44 Engaging Physicians & Health Care Systems physicians & the health care systems in which they operate are key to making sure that all patients get the very best care.

45 LESSONS FOR HEALTH CARE REFORM (1) Performance reports by race/ethnicity 2009 IOM report underscores importance of consistent reporting of quality data by race and ethnicity Broad quality improvement efforts reduce disparities in processes of care Disparities diminish in more organized systems: e.g. Medicare HMOs, integrated medical groups

46 LESSONS FOR HEALTH CARE REFORM (2) Focused interventions in health systems & communities required to achieve equity in health outcomes: Universal insurance coverage is essential foundation More effective coordination of care Community engagement and policy interventions to address social determinants of health outcomes ACO s, patient-centered medical homes & managed care plans must strive to meet these challenges
