Social Determinants of Health: Advocacy and Patient Resources
Where a person lives, what they earn, whether they finished high school, and how safe their neighborhood feels after dark — these factors shape health outcomes as powerfully as any prescription. Social determinants of health (SDOH) are the non-medical conditions of daily life that drive roughly 80 percent of health outcomes, according to the Kaiser Family Foundation's analysis of SDOH research. This page covers what those determinants are, how advocacy systems engage with them, and when a patient or caregiver needs to push harder for structural support.
Definition and scope
The World Health Organization defines social determinants of health as "the conditions in which people are born, grow, live, work, and age." That definition is deceptively simple. It encompasses income and wealth, educational attainment, employment status, housing stability, food security, transportation access, neighborhood safety, social connection, and exposure to discrimination.
The U.S. Department of Health and Human Services organizes these under 5 domain categories in its Healthy People 2030 framework: Economic Stability, Education Access and Quality, Health Care Access and Quality, Neighborhood and Built Environment, and Social and Community Context. Each domain interacts with the others — food insecurity tends to cluster with housing instability, which compounds transportation barriers to medical appointments, which worsens chronic disease management. None of these domains operates in isolation.
Patient advocacy in the SDOH space sits at the intersection of key dimensions of patient advocacy and social services navigation. An advocate operating here is not just helping someone understand a diagnosis — they are helping someone survive the conditions that make the diagnosis harder to treat.
How it works
SDOH advocacy generally moves through 3 distinct mechanisms.
-
Screening and identification. Health systems and community organizations use validated tools — the most widely adopted being the PRAPARE (Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences) tool — to identify which social needs a patient carries into a clinical encounter. A patient flagged for food insecurity at a PRAPARE screening is not simply handed a pamphlet; a trained care coordinator or advocate is typically assigned to connect them to concrete resources.
-
Resource navigation and referral. Once a need is identified, advocates use community resource databases — platforms like FindHelp (formerly Aunt Bertha) operate in every U.S. state — to match patients with local programs. This step requires knowing which programs have current availability, what documentation is required, and whether language access or transportation assistance is bundled in.
-
Policy and systemic advocacy. Individual navigation is necessary but not sufficient. Structural advocates — working through hospital community benefit offices, community health workers, legal aid partners, and patient advocacy organizations — push for policy changes that address root causes. Medicaid waivers in states like North Carolina have begun explicitly funding housing-related services for high-utilization populations, a model that CMS tracks under Section 1115 demonstration waivers.
A patient wondering how to get help for patient advocacy in an SDOH context often needs all 3 layers, even if only one is immediately visible to them.
Common scenarios
Four patterns appear with regularity in SDOH advocacy practice.
Housing instability before hospital discharge. A patient discharged from a 5-day inpatient stay to a shelter or unstable housing has a measurably higher 30-day readmission rate. Discharge planners and patient advocates coordinate with housing case managers to prevent the gap between clinical care and safe shelter from becoming a revolving door.
Medication cost as a silent barrier. A patient who cannot afford a $300-per-month co-pay for a maintenance medication simply stops taking it. Advocates in this scenario work through pharmaceutical patient assistance programs, state pharmacy assistance programs, and — where applicable — Extra Help under Medicare Part D, which the Social Security Administration administers.
Food insecurity and chronic disease management. Diabetes management is substantially harder when a patient's food access is limited to convenience stores within a 2-mile radius. Advocates connecting patients to medically tailored meal programs or SNAP enrollment support are doing clinical-quality work by another name.
Transportation barriers to specialty care. A patient referred to an oncologist 60 miles away who lacks a car and cannot afford rideshare costs will simply not go. Non-emergency medical transportation (NEMT) is a mandatory Medicaid benefit under 42 CFR § 431.53, though coverage and implementation vary significantly by state.
Decision boundaries
Not every SDOH need falls within the scope of patient advocacy — and knowing that boundary matters.
SDOH advocacy is appropriate when a social need is directly affecting health access, treatment adherence, or health outcomes. It is not a substitute for social work licensure, legal representation, or emergency services. When a patient faces active domestic violence, eviction proceedings, or debt collection for medical bills, the correct referral is a trained social worker or legal aid attorney — not a patient advocate operating outside their lane.
The contrast worth holding clearly: reactive SDOH support addresses a social barrier after it has already disrupted care (the missed appointment, the unfilled prescription). Proactive SDOH advocacy integrates screening, resource connection, and policy pressure before the barrier becomes a crisis. Health systems that screen 100 percent of patients at intake — a goal embedded in the CMS Interoperability and Patient Access framework — are moving toward the proactive model, however unevenly.
