4.3 Community Health Partnerships & Social Determinants of Health
Key Takeaways
- Internal Revenue Code §501(r)(3), established under the Affordable Care Act, mandates that non-profit hospitals conduct a Community Health Needs Assessment (CHNA) every three years and adopt an authorized Implementation Strategy.
- Social Determinants of Health (SDOH) drive up to 80% of health outcomes; systematic screening for individual Health-Related Social Needs (HRSNs) targets 5 core domains: housing instability, food insecurity, transportation barriers, utility assistance, and interpersonal safety.
- Community Health Workers (CHWs) and Promotores de Salud provide vital cultural bridging, health coaching, and trust-building that link marginalized patients to clinical care and social resources.
- Sustainable cross-continuum partnerships rely on closed-loop technology platforms (e.g., Unite Us, Findhelp) and the Collective Impact framework to ensure accountable referral fulfillment and shared community health outcomes.
4.3 Community Health Partnerships & Social Determinants of Health
Quick Answer: Patient experience does not occur in a vacuum; clinical outcomes and human experience are heavily dictated by the conditions in which patients live, work, and age. Under Section 501(r)(3) of the Affordable Care Act, tax-exempt non-profit hospitals must conduct a triennial Community Health Needs Assessment (CHNA) and adopt a formal Implementation Strategy. Modern patient experience leadership integrates systematic screening for Health-Related Social Needs (HRSNs)—focusing on housing, food, transportation, utilities, and safety—and partners with Community Health Workers (CHWs) and community-based organizations (CBOs) through closed-loop referral networks.
Healthcare organizations that limit their patient experience efforts to the four walls of the hospital or clinic fail to address the systemic root causes of health disparities, readmissions, and patient distress. Achieving true health equity and sustainable clinical excellence demands authentic community engagement and cross-continuum partnerships.
Community Health Needs Assessments (CHNA) Under ACA §501(r)
Under Section 501(r)(3) of the Internal Revenue Code, enacted as part of the Affordable Care Act (ACA), all 501(c)(3) tax-exempt hospital organizations must conduct a Community Health Needs Assessment (CHNA) at least once every three years (triennially) and adopt an Implementation Strategy (also known as a Community Health Improvement Plan, or CHIP).

Statutory CHNA Requirements & Governance Rules
- Mandatory Community Input: The hospital must solicit and incorporate broad community input, explicitly including: (1) individuals with special knowledge of or expertise in public health, (2) representatives of medically underserved, low-income, and minority populations, and (3) written comments received on the most recently conducted CHNA.
- Board-Approved Implementation Strategy: The hospital must develop a written Implementation Strategy approved by the hospital's governing board detailing how it will address each identified health need, or explain why it does not intend to address a specific need (e.g., lack of financial resources or addressed by other community entities).
- Public Availability & Schedule H (Form 990): The finalized CHNA report must be made widely available to the public on the hospital's website, and compliance must be reported annually on IRS Form 990, Schedule H.
- Non-Compliance Penalties: Failure to meet CHNA requirements results in a $50,000 excise tax penalty under IRC §4959 for each non-compliant tax year and risks the revocation of the hospital's 501(c)(3) tax-exempt status.
Screening for SDOH & Health-Related Social Needs (HRSNs)
While Social Determinants of Health (SDOH) refer to the broad structural conditions in which people are born, grow, live, work, and age, Health-Related Social Needs (HRSNs) represent individual-level adverse social conditions that directly compromise a patient's health and clinical outcomes.
+--------------------------------------------------------------------------+
| THE FIVE CORE CMS / AHC SCREENING DOMAINS (HRSNs) |
+------------------------------------+-------------------------------------+
| HRSN DOMAIN | OPERATIONAL SCREENING FOCUS |
+------------------------------------+-------------------------------------+
| 1. Housing Instability | Homelessness, frequent moves, |
| | poor housing quality (mold, pests). |
+------------------------------------+-------------------------------------+
| 2. Food Insecurity | Inability to afford balanced meals; |
| | skipping meals due to lack of money.|
+------------------------------------+-------------------------------------+
| 3. Transportation Insecurity | Lack of reliable transport for |
| | medical appointments, work, or food.|
+------------------------------------+-------------------------------------+
| 4. Utility Difficulty | Inability to pay electric, heating, |
| | or water bills; shutoff notices. |
+------------------------------------+-------------------------------------+
| 5. Interpersonal Safety | Domestic violence, physical abuse, |
| | elder neglect, neighborhood danger. |
+------------------------------------+-------------------------------------+
Standardized Screening Tools & Clinical Integration
Healthcare systems utilize standardized, validated screening instruments such as the CMS Accountable Health Communities (AHC) Health-Related Social Needs Screening Tool and the PRAPARE (Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences) instrument.
- Trauma-Informed & Respectful Screening: Screening must be conducted with cultural humility. Staff must explain why questions are being asked (e.g., "We ask all patients these questions because housing and food affect your health and recovery").
- ICD-10 Z-Codes (Z55–Z65): Documenting identified social needs in the EHR using standardized Z-codes (e.g., Z59.0 for homelessness, Z59.4 for food insecurity) allows health systems to track population-level social risk factors and stratify clinical outcomes.
- CMS Inpatient Quality Reporting (IQR) Mandate: CMS quality measures require hospitals to report the percentage of admitted patients screened for the 5 core HRSNs, reinforcing SDOH as a core quality and experience metric.
Integrating Community Health Workers (CHWs) & Promotores de Salud
Community Health Workers (CHWs)—also known in Hispanic/Latino communities as Promotores de Salud—are trusted frontline public health workers who share the ethnicity, language, socioeconomic background, and lived experience of the communities they serve.
CORE ROLES OF COMMUNITY HEALTH WORKERS
[ CULTURAL BRIDGING ] ---> Translates clinical plans into cultural context
[ SYSTEM NAVIGATION ] ---> Guides patients through fragmented social & health systems
[ HOME VISITS & COACHING] ---> Assesses real-world living environments & medication adherence
[ ADVOCACY & TRUST ] ---> Serves as trusted liaison between marginalized patients & clinicians
Clinical and Experience Impact of CHWs
Integrating CHWs into multidisciplinary clinical teams (working alongside physicians, nurses, and social workers) produces transformative clinical and experience results:
- Mitigating Medical Mistrust: Patients from historically marginalized communities who may distrust large healthcare institutions readily confide in CHWs who share their cultural background.
- Reducing Preventable Hospital Readmissions: CHWs conduct post-discharge home visits to inspect home safety, verify food availability, ensure prescriptions are filled, and coordinate transportation to follow-up visits.
- Chronic Disease Control: CHW health coaching dramatically improves glycemic control (HbA1c) in type 2 diabetes and blood pressure control in hypertension across vulnerable populations.
Cross-Continuum Partnerships & Closed-Loop Referral Ecosystems
Historically, when healthcare providers identified a social need (such as food insecurity), they handed the patient a paper list of community food pantries. This created a "referral black hole"—clinicians had no visibility into whether the patient ever reached the pantry or received assistance.
Closed-Loop Technology Platforms
Modern patient experience networks utilize closed-loop referral platforms (e.g., Unite Us, Findhelp/Aunt Bertha) integrated directly into the EHR:
- Electronic Screening & Referral: The clinician identifies a need and sends an electronic referral directly to a vetted Community-Based Organization (CBO).
- CBO Intake & Fulfillment: The CBO accepts the referral, delivers the service (e.g., provides a box of food or pays an electric bill), and updates the case in the platform.
- Closed-Loop Status Notification: The platform writes back to the patient's EHR chart, notifying the clinical team that the social need was successfully resolved.
The Collective Impact Framework for Community Health
To achieve population-level health transformation, health systems partner with local governments, schools, non-profits, and businesses using the Collective Impact Framework:
| Collective Impact Condition | Health System Operational Application |
|---|---|
| 1. Common Agenda | Health system and community partners agree on shared priorities identified in the CHNA (e.g., reducing maternal mortality in zip code 12345). |
| 2. Shared Measurement | All participating organizations track identical metrics (e.g., prenatal visit attendance, gestational diabetes rates). |
| 3. Mutually Reinforcing Activities | Hospital provides clinical obstetrical care; CBO provides doula support and maternal food boxes; housing agency provides stable shelter. |
| 4. Continuous Communication | Monthly cross-agency huddles and shared data dashboards to maintain relational trust. |
| 5. Backbone Support Organization | Dedicated staff (often housed within the hospital's community health division) coordinating logistics, data analysis, and funding. |
