About This Series: The HIMSS Word of the Day is a running blog series drawing from the HIMSS Dictionary of Health Information and Technology Terms, Acronyms, and Organizations, 6th Edition (2025) — the authoritative reference for healthcare IT professionals and the primary study resource for CAHIMS and CPHIMS certification. Each post paraphrases the term in plain language, grounds it in real-world healthcare IT context, and adds a bedside nursing perspective you won’t find in a textbook.
📖 The Term: Social Determinants of Health (SDoH)

🔍 Plain-Language Definition
Social determinants of health (SDoH) are the everyday conditions of people’s lives, such as income, housing, education, food, transportation, and community, that shape how healthy they are and how long they live.
The HIMSS Dictionary describes SDoH as the economic and social conditions that influence differences in health between individuals and groups, along with how those conditions are spread across the population. It stresses that SDoH are found in the circumstances of daily living and working, including how income, wealth, influence, and power are distributed, and it contrasts them with individual risk factors, such as personal behaviors or genetics.
Healthy People 2030, from HHS’s Office of Disease Prevention and Health Promotion, groups SDoH into five domains:
| Domain | What It Covers | Example Questions in Practice |
|---|---|---|
| Economic Stability | Income, employment, food security, housing stability | Has the patient worried about running out of food? |
| Education Access and Quality | Early education, literacy, language, higher education | Does the patient need help reading health materials? |
| Health Care Access and Quality | Insurance coverage, access to primary care, health literacy | Does the patient have a regular source of care? |
| Neighborhood and Built Environment | Housing quality, transportation, safety, environmental conditions | Can the patient get to follow-up appointments? |
| Social and Community Context | Social support, discrimination, civic participation, incarceration | Does the patient have someone to help at home? |
⚠️ Exam Alert: Social determinants of health describe community-level conditions that affect everyone in a population. Health-related social needs (HRSN) are the individual-level unmet needs, such as food insecurity or housing instability, that a specific patient experiences. Health equity is the goal of giving everyone a fair opportunity to be as healthy as possible. Screening tools capture social needs; policy and community investment address the determinants. Some organizations now use the phrase social drivers of health for the same concept.
🌐 Why It Matters: Real-World Healthcare IT Context
Clinical care is only one of many influences on health, and many experts estimate that it accounts for a minority of what drives outcomes. A patient’s ZIP code, income, and support at home can matter as much as the treatment plan.
That reality has moved SDoH from public health into clinical operations, largely because of value-based care. Accountable Care Organizations and other organizations that take financial responsibility for a population have strong reasons to identify patients whose social needs drive avoidable emergency visits and readmissions. CMS tested this through its Accountable Health Communities Model, which screened Medicare and Medicaid beneficiaries for health-related social needs and connected them with community services. Its screening tool focused on five core needs: housing instability, food insecurity, transportation problems, utility help needs, and interpersonal safety.
Health IT makes SDoH data usable. Screening questionnaires capture answers as structured data. ICD-10-CM Z codes, especially categories Z55 through Z65, record social circumstances in a form that can be counted and reported. LOINC and SNOMED CT provide codes for screening questions, answers, and findings. The Gravity Project, an HL7 FHIR Accelerator, develops consensus data standards for SDoH assessments, goals, and interventions, and recent versions of USCDI include SDoH data elements so they can be exchanged between systems.
SDoH data also brings responsibility. Sensitive information about housing, safety, or immigration-related concerns must be protected, and models that use neighborhood or income data can reinforce bias if they are not checked carefully.
Common pitfalls with SDoH data:
- Screening without a plan or resources to respond to positive results
- Asking the same questions repeatedly across visits and departments
- Free-text documentation that cannot be counted or shared
- Low use of Z codes, which hides social needs from reporting
- Referrals sent to community organizations with no closed-loop follow-up
- Questions asked in ways that feel judgmental or unsafe to patients
Characteristics of effective SDoH programs:
- Validated, standardized screening tools captured as structured data
- Clear workflows for who screens, how often, and who responds
- Community resource directories and closed-loop referral platforms
- Coding of social needs with Z codes and standard terminologies
- Privacy protections and patient choice about what is shared
- Use of SDoH data to improve programs, not just to stratify risk
🏥 The Nurse’s Perspective: Clinical, Bedside, & Workflow
Nurses have long understood that what happens at home shapes recovery, and SDoH screening gives that knowledge a structured place in the chart.
At the Bedside
Many admission assessments now include questions about food, housing, transportation, utilities, and safety. Nurses who ask those questions with privacy and respect often learn information that changes the plan of care, such as a patient who cannot refrigerate insulin, has no ride to dialysis, or rations medications because of cost.
The way questions are asked matters. Explaining why the questions are asked, offering privacy, and making clear that answers will be used to help, not to judge, makes honest answers more likely.
In Clinical Workflow
A positive screen should lead to action. Nurses often route results to case management or social work, and some organizations use referral platforms that send requests directly to food banks, transportation services, or housing programs. Discharge planning depends on that information, because a plan that assumes reliable transportation or a safe home may fail on the first day.
Documentation habits make the data useful later. Recording answers in structured fields, rather than burying them in a narrative note, allows care managers, population health teams, and quality programs to find patients who need support.
In EHR Implementation (Go-Live Perspective)
During an Epic Go-Live, SDoH questionnaires are often new to nursing workflows. Teams have to decide which screening tool to use, which department asks the questions, how often they are repeated, and where the results display. At-the-elbow support analysts frequently help nurses find the SDoH section, understand which questions are required, and see whether a patient was already screened recently in another department.
Good design avoids repeated screening. When results from a clinic visit last month are visible on admission, nurses can confirm and update them instead of asking every question again, which respects the patient’s time and keeps the data current.
🎓 CAHIMS / CPHIMS & HIMSS Perspective
CAHIMS Exam Domain Mapping
SDoH appears in questions on population health, data standards, and value-based care:
| CAHIMS Domain | How SDoH Appears |
|---|---|
| Healthcare & Technology Environments | Health equity; Healthy People 2030; value-based payment; CMS innovation models |
| Clinical Informatics | Screening workflows; care planning; referral management; patient privacy |
| Healthcare Information & Systems Management | Z codes, LOINC and SNOMED CT coding, USCDI data elements, FHIR-based exchange |
| Management & Leadership | Community partnerships; program evaluation; responsible use of SDoH data in analytics |
Key Terms to Know Alongside SDoH
- Health-Related Social Needs (HRSN) — individual-level adverse social conditions, such as food insecurity or housing instability, that affect health
- Health Equity — the state in which everyone has a fair and just opportunity to attain their highest level of health
- Z Codes — ICD-10-CM codes used to document social and economic circumstances that influence health
- Gravity Project — an HL7 FHIR Accelerator that develops consensus data standards for social determinants of health
- Closed-Loop Referral — a referral process that confirms whether the patient received the service
- Population Health — the health outcomes of a group of individuals and the distribution of those outcomes within the group
HIMSS Organizational Position
HIMSS addresses SDoH through its health equity and population health work. Its Global Health Equity Community brings together professionals focused on using information and technology to reduce disparities, and HIMSS engages on related data standards and policy through its public policy work. Members can find related education and research through the HIMSS Resource Center.
