Agenda
1. What are social determinants?2. Current limits to social determinant
intervention research. 3. Bridging the gap in two directions.
a. Social determinants to health recordsb. Health records to social determinants
4. The common link: Residence

Social determinants of health
Upstream elements of a society’s organization and process, such as education, housing, transportation, occupation, the system of justice, that causally affect the societal distribution of disease and health. Social determinants may affect health by distributing risk and protective factors for disease and injury, pathological agents and environments, and resources for prevention and treatment.

Goals for Social Determinant Data and Research
1. Improve care of patient with EHR.
2. Improve community/public health with EHR-generated information.
3. Etiological research, e.g., assessing poverty or lack of education as causes of reduced longevity.
4. Monitoring trends in social determinants, e.g., changes in education achievement gaps by race and income.
5. Evaluating social determinant interventions, e.g., the effect of high school completion programs on long term health outcomes.
Long-term Improvement of population health
Short-term Improvement of patient/community health

Guide to Community Preventive Services Reviews of Educational Interventions to
Promote Health EquityPast 4 years, systematic reviews of educational programs, e.g.:
Early childhood education
Full-day vs. half-day kindergarten
Out-of-school time academic programs
High school completion
School based health centers
Extended school day and year
Underlying question: Can social determinant interventions be used to promote health equity?
7
Range of Variables Considered in Reviews of Educational Interventions to
Promote Health Equity Intervention characteristics, e.g., contents, intensity,
duration.
Student participation, e.g., proportion enrollment, program completion rate.
Educational outcomes, e.g., standardized achievement tests, levels of school completion, school grades.
Quality of school, e.g., high school completion rates, average test scores, teacher: student ratio or classroom size, hours of instruction.
School demographics, e.g., proportion minority, proportion receiving free or reduced-price lunch, community.

Major Challenge in Educational Intervention Reviews for Health Equity
Outcomes assessed are primarily educational, e.g., changes in reading or math achievement scores, or rates of high school graduation, not health outcomes
To draw conclusions about health outcomes, we have to:
make assumptions about the education—health link. Assumptions are frequently challenged and difficult to prove.
use evidence from other studies.
Linkage to heath outcomes would provide an enormous advance in this research

Challenges of Linkage for this Committee: From EHR to Social Determinants
Inclusion of extensive set of social determinant data in EHR is undesirable and unnecessary; would be a large burden for health care system.
Use LINKAGE. Linkage should be purpose-driven, i.e., what are the goals, what question asked, what to be achieved?
Requires common, shared identifiers. Useful linkages may be either for the
individual in the record, e.g., years of school completed, or for an aggregate associated with the individual, e.g., quality measures of the school, or the poverty level in the census tract. (E.g., Krieger, www.hsph.harvard.edu/thegeocodingproject/)

Allows linkage to community resources (and their absence), depending on data from other sources.

Summary: A Gap Separates EHR and Social Determinants of Health
Merits bridge building in both directions.
EHR cannot include large arrays of social determinant data.
EHR can link to wide variety of social determinant data.
Linking requires common variables. Because residence commonly
defines resources, it provides an optimal link between EHR and social determinant data.
