Presentation Transcript
slide1. Xing Song, PhD
University of Missouri Linkage strategies to integrate multi-level social determinants of health (SDoH) data<br>
slide2. Agenda What is SDoH
Current linkage and integration strategy
Accessing SDoH on GROUSE
Acxiom household- and individual-level SDOH
Plan for pilot analysis<br>
slide3. What is SDOH Healthy People 2030, U.S. Department of Health and Human Services, Office of Disease Prevention and Health Promotion. The U.S. Department of Health and Human Services's Healthy People 2030 project groups SDoH into five domains:
Economic Stability
Education Access and Quality
Health Care Access and Quality
Neighborhood and Built Environment
Social and Community Context<br>
slide4. SDOH Domains<br>
slide5. Current strategy of integrating SDOH Current state-of-the-art method for integrating SDOH data is still mostly based on community-level summaries Economic Stability; Education Access; Health Care Access; Neighborhood and Built Environment; Social and Community Context<br>
slide6. Accessing SDoH on GROUSE Current deployed resources:
Neighborhood Atlas Area Deprivation Index (2020)
By-product: zip+4 -> census block group mapping
Curated SDoH dataset from Nebraska CRANE database
Bird Index (ACS derivative)
55 calucated ACS (2019) variables mapped to SNOMED
RUCA (2010)
Current deployment strategy integrating into CDM
Link to ADDRESS_HISTORY by GEOCODEID (census block group, census tract, zip)
OBS_COMM<br>
slide7. Query Example - Extract OBS_COMM variables at census tract level - Extract OBS_COMM variables at census block group level<br>
slide8. Household- or Individual-level SDoH Limitation of community-level SDoH
Reduce variation
14M beneficiary, 5.5M unique zip+4, 163K unique census block group codes
Ecological fallacy
when inferences about the nature of individuals are deduced from inferences about the group to which those individuals belong
From existing sources
Extraction from EHR or Claim data
Integration of external sources?
Acxiom
LexisNexis<br>
slide9. Acxiom InfoBase Acxiom is one of the largest consumer database
Data sources
public records, such as property ownership or professional licenses.
consumer surveys, magazine subscriber lists, catalogs, and warranty cards
summary reports about retail purchases
voter registration records, criminal records

Available from 2012 to 2022
Updates twice each year
Not all attributes are available in historical data (still exploring)
Additional charges
