An Approach to Selecting Single or Multiple Social Risk Factors for Clinic-Based Screening

Racial and Ethnic Equity in Care for Hypertension and Diabetes in an Urban Indian Health Organization

Approximately 70% of American Indian/Alaska Native (AI/AN) individuals reside in urban areas. Urban Indian Health Organizations (UIHOs) provide culturally engaged primary care for AI/AN patients and members of other racial and ethnic groups who have experienced disparities in diabetes and hypertension care, and are commonly affected by social and economic barriers to care. We assessed whether disparities were present between the racial and ethnic groups served by the largest UIHO in the USA. We developed retrospective cohorts of patients with hypertension or diabetes receiving primary care from this UIHO, measuring differences between AI/AN, Spanish-preferring Latinx, English-preferring Latinx, Black, and White patients in mean systolic blood pressure (SBP) and mean hemoglobin A1c (A1c) as primary outcomes. To assess processes of care, we also compared visit intensity, missed visits, and medication treatment intensity in regression models adjusted for sociodemographic and clinical characteristics. For hypertension (n = 2148), adjusted mean SBP ranged from 135.8 mm Hg among Whites to 141.3 mm Hg among Blacks (p = 0.06). For diabetes (n = 1211), adjusted A1c ranged from 7.7% among English-preferring Latinx to 8.7% among Blacks (p = 0.38). Care processes for both hypertension and diabetes varied across groups. No group consistently received lower-quality care. This UIHO provided care of comparable quality for hypertension and diabetes among urban-dwelling AI/ANs and members of other racial, ethnic, and language preference groups. Systematic assessments of care quality in UIHOs may help demonstrate the importance of their role in providing care and improve the quality of care.

Associations Between Different Self-reported Social Risks and Neighborhood-level Resources in Medicaid Patients

BACKGROUND

Adverse social conditions are a key contributor to health disparities. Improved understanding of how social risk factors interact with each other and with neighborhood characteristics may inform efforts to reduce health disparities.

DATA

A questionnaire of 29,281 patients was collected through the enrollment of Medicaid beneficiaries in a large Northern California integrated health care delivery system between May 2016 and February 2020.

EXPOSURES

Living in the least resourced quartile of neighborhoods as measured by a census-tract level Neighborhood Deprivation Index score.

MAIN OUTCOMES

Five self-reported social risk factors: financial need, food insecurity, housing barriers, transportation barriers, and functional limitations.

RESULTS

Nearly half (42.0%) of patients reported at least 1 social risk factor; 22.4% reported 2 or more. Mean correlation coefficient between social risk factors was ρ=0.30. Multivariable logistic models controlling for age, race/ethnicity, sex, count of chronic conditions, and insurance source estimated that living in the least resourced neighborhoods was associated with greater odds of food insecurity (adjusted odds ratio=1.07, 95% confidence interval: 1.00-1.13) and transportation barriers (adjusted odds ratio=1.20, 95% confidence interval: 1.11-1.30), but not financial stress, housing barriers, or functional limitations.

CONCLUSIONS AND RELEVANCE

We found that among 5 commonly associated social risk factors, Medicaid patients in a large Northern California health system typically reported only a single factor and that these factors did not correlate strongly with each other. We found only modestly greater social risk reported by patients in the least resourced neighborhoods. These results suggest that individual-level interventions should be targeted to specific needs whereas community-level interventions may be similarly important across diverse neighborhoods.
