Patient-physician racial concordance, effectiveness of care, use of services, and patient satisfaction

1. Patient-physician racial concordance,effectiveness of care, use of services, and patient satisfaction Thomas R. Konrad, Ph.D.1 Daniel L. Howard, Ph.D.2 1 University of North Carolina at Chapel Hill, Cecil G. Sheps Center for Health Services Research, UNC-CH 2 Shaw University

2. Background:Racial disparities exist in the health care workforce • Racial and ethnic minorities are under represented in the medical workforce when compared to their representation in the population

3. Three arguments for increasing numbers of minority health professionals.... • Fairness: • Providing equal opportunity for disadvantaged minorities • Access: • Making health services available to underserved communities and patients. • Effectiveness: • Increasing the effectiveness of care received by minority communities and patients

4. Fairness: • It’s the right thing to do • This argument is based on fairness and justice to providers not communities or patients • No necessity to argue about “health” or “health care” issues.

5. Access • Minority physicians are more likely than others to serve poor, under-served, minority, and rural areas. • Access to some care is better than no care (Bernard 1997); minority physicians are more likely to provide that access. • Assumes that a public good is at stake

6. Effectiveness • Argues that racial concordance between patients and providers makes delivery of care work better. • African American patients require African American physicians because they understand the cultural and social context of illness in the African American community. • Better communication and understanding may resulte in better health outcomes and more effective care • Arguments about effectiveness are more appealing to policy makers in a climate of fiscal restraint

9. Policy questions • Do providers beliefs about patients affect their behavior? • Conscious and unconscious • “Stereotyping” • Race ethnicity can be confounded with clinical condition, site, payer

10. The purpose of this line of research is to ask: • Do African American patients receive more effective care from African American physicians than do similar patients with White physicians? • How do both groups of African American patients compare with white patients receiving care from either White or African-American physicians?

11. Our first study ... • Examined a sample of elderly African American and White respondents to the a community based survey, • Identified their usual care physician (whether African American or White), if they had one • Omitted individuals without a regular physician (respondents without doctors are disproportionately African-American) • Assessed the impact of Patient-physician relationship using several patient care outcome measures.

12. Today’s presentation • Reviews initial reports on results of a cross sectional study using patient-physicianconcordance by race in a follow-up sample. • Describes the data and analysis plan for ongoing longitudinal studies of patient- physician racial concordance on effectiveness of care. • Alludes to issues of continuity of care in subsequent planned research.

28. Bivariate results:Racial dyads & dependent variables only • There were only a SMALL number of White patients w/ African American physicians. • White patients w/ African American physicians were more likely to be told of high blood pressure (47%) and given high blood pressure medication (42%) and currently taking high blood pressure medication (37%) • White patients w/ African American physicians are more likely to delay care (33%), be very dissatisfied w/ care (11%) and are least likely to be very satisfied w/ care (17%) • The opposite is true for White patients w/ White physicians; white patients w/ white physicians put off care least (14%) and are most likely to be very satisfied w/ care (43%) • No differences across the 4 groups in actual blood pressure being high, ER visits / total visits, and being dissatisfied w/ care.

37. Conclusions of first study • Minimal differences between African American and White physicians in patterns of care delivery. • Age and gender of physician is important for patient satisfaction. • Higher satisfaction among African American patients with white doctors than with African American doctors. • Least satisfaction among White patients with African American doctors (small numbers).

38. Conclusions (cont.) The higher level of satisfaction among African American patients occurred with White physicians … a group of physicians more likely to be female … a group of patients more likely to be female.

39. Limitations of the first study • One patient-physician dyad had only36 patients and 3 physicians • Cross-sectional data and therefore causality between independent and dependent variables could not be established • Limited to one time period (1986)

40. New Study Addresses previous limitations • Longitudinal analyses possible • Better satisfaction measure available • Effects of continuity of care (having SAME physician) can be addressed in addition to the issue of patient-physician racial concordance.

41. 34 African American doctors served 462 African Americans (21%) 110 White doctors served 602 African Americans (27%) 2 African American doctors served 30 Whites (1%) 162 White doctors served 1,142 Whites (51%) Patient-physician racial dyads

42. physicians (by race) • No differences by race by physician gender or experience (yrs. since medical school) • AA MDs more likely 65+ years old (p<.001)

43. Bivariate results:Racial dyads & dependent variables only • There were only a SMALL number of White patients w/ African American physicians. • No differences across the 4 groups in actual blood pressure being high. • White patients w/ white physicians were least likely to be told of high blood pressure (55%). • African American patients w/ African American physicians were more likely to be told of high blood pressure (85%). • White patients w/ African American physicians were least likely to be very satisfied w/ care (10%), while white patients w/ white physicians were most likely to be very satisfied w/ care (40%). • Satisfaction w/ care remained the same between 1986 and 1990 for African Americans w/ African American physicians, while the other dyads experienced decreases in satisfaction over the years.

44. High Satisfaction w/ Care1986-1990

45. Continuity of Care

46. Initial thoughts regarding second study • Again, minimal differences between African American and White physicians in patterns of care delivery. • High satisfaction among African American patients with white doctors dramatically decreased in 1990 vs. 1986 (34% vs. 25%). • High satisfaction among African American patients w/ African American doctors remained constant between 1986 and 1990 (27%). • Greater continuity of care (having the same physician over time) among same-race patient-physician dyads.

47. Preliminary analyses from new study • Measure satisfaction in a more sophisticated way • Special sensitivity to an aging population

48. Satisfaction items • Doctors always do their best to keep patients as old as I am from worrying • Doctors always treat their patients my age with respect. • Sometimes doctors make patients my age feel foolish.

49. Satisfaction items • When treating people about my age doctors always avoid unnecessary patient expenses. • Doctors often cause patients my age to worry a lot, because they don’t explain things well. • When treating people about my age, doctors respect their patients’ feelings.

50. Satisfaction items • Doctors never recommend an operation for people my age, unless there is no other way to solve the problem. • Doctors don’t pay enough attention to the health problems that people my age have. • Most of these younger doctors really understand how people my age feel. • Sometimes doctors think that just getting old is a disease that can’t be cured.
