Abstract/Excerpt

Introduction: Given the increasing impact of the healthcare cost of hypertension on the economy, understanding the control of high blood pressure is warranted, particularly as it pertains to racial/ethnic disparities in hypertension control.

Objective: To understand the relationship between hypertension control and racial/ethnic concordance, we investigated whether the racial/ethnic concordance between a patient’s race/ethnicity and that of the individual’s provider is a predictor of high blood pressure control.

Methods: Data was collected for 612,524 patients from Kaiser Permanente Southern California who were at least 18 year old and received a diagnosis of hypertension between January 1, 2016 and December 31, 2019. A multiple regression analysis was carried out to assess the correlation between hypertension control and patient-provider concordance.

Results: The independent variables proxying for patient-provider relationship are positive and statistically significant at the 5% level. Out of the 3 types of concordance, language has the highest standardized estimate, followed by gender and race.

Discussion: We found correlations between racial/ethnic patient-provider concordance and hypertension control. Consistent with previous studies, we found that Asian patients experience more time in hypertension control. By contrast, Black and Hispanic patients have less time in hypertension control. Having the same primary care provider for a longer span of time is also positively correlated with length of hypertension control.

Conclusion: Correlation between racial/ethnic concordance, length of time under the primary provider’s care, and length of time spent in hypertension control suggests that the patient-provider relationship remains a critical component of health outcomes.
