Social Determinants of Wound Healing: Assessment Guide

Social Determinants of Health Shape Wound Healing

Social determinants of wound healing are the non-clinical factors — housing, food access, transportation, income, social support, and neighborhood environment — that determine whether a wound heals or stalls. A clinician can provide the right debridement, the right dressing, and the right offloading device at every visit, and the wound will still fail to close if the patient goes home to a moldy apartment, cannot afford protein-rich food, has no ride to follow-up appointments, or lives alone with no one to help with dressing changes.

Research estimates that clinical care accounts for only 20 percent of health outcomes. The remaining 80 percent is driven by social, environmental, and behavioral factors. In wound care, this ratio may be even more skewed because chronic wounds demand sustained daily management in the patient's own environment — an environment the clinician does not control and often does not assess.

Wound care practices that screen for social determinants and connect patients with resources see faster healing times, fewer missed appointments, and lower readmission rates. This is not social work for its own sake. It is a clinical strategy for improving wound outcomes.

How Specific Social Determinants Affect Wound Healing

Housing Instability

Housing affects wound care in multiple direct ways:

Homelessness or unstable housing makes daily wound care impossible. Patients without a clean, private space cannot perform dressing changes safely.
Substandard housing with mold, pest infestations, or lack of running water increases infection risk and undermines wound healing.
Housing insecurity — fear of eviction, frequent moves, couch-surfing — creates chronic stress that impairs immune function and disrupts care continuity.
Lack of climate control. Extreme heat or cold affects skin integrity, edema, and the viability of wound care supplies stored in the home.

For patients without stable housing, wound care treatment plans must account for this reality rather than assume a standard home care environment.

Food Insecurity and Nutritional Deficiency

Wound healing requires adequate protein, calories, vitamins A and C, zinc, and iron. Food-insecure patients are unlikely to meet these nutritional demands:

Protein malnutrition slows granulation tissue formation and delays closure. Chronic wound patients need 1.25 to 1.5 grams of protein per kilogram of body weight daily — a level that food-insecure patients rarely achieve.
Caloric insufficiency diverts energy from wound repair to basic metabolism.
Micronutrient deficiency (vitamin C, zinc, iron) impairs collagen synthesis and immune response.

The typical supplemental nutrition advice given to wound care patients — "eat more protein, take a multivitamin" — is useless if the patient cannot afford groceries. Screening for food insecurity is a prerequisite for meaningful nutritional intervention.

Transportation Barriers

Chronic wound care requires frequent follow-up visits — often weekly. Transportation barriers create treatment gaps that directly slow healing:

Lack of personal vehicle. Rural wound care patients may live 30 or more miles from the nearest wound care provider.
Public transportation limitations. Fixed schedules, limited routes, and physical accessibility barriers make public transit impractical for many wound care patients, especially those with mobility limitations.
Cost of transportation. Gas, parking, rideshare fees, and public transit fares accumulate over months of weekly visits.
Dependence on others. Patients who rely on family or friends for rides are constrained by their driver's availability, which may not align with appointment times.

Understanding why some wounds don't heal despite appropriate clinical care often starts with these social factors. See our article on why wounds don't heal for the full clinical and non-clinical picture.

Social Isolation

Social isolation affects wound healing through multiple pathways:

No caregiver support. Isolated patients must perform all wound care independently, which may be physically impossible for certain wound locations or complex dressing regimens.
Depression and hopelessness. Social isolation is a primary driver of depression, which impairs immune function and reduces treatment adherence.
Delayed emergency response. Patients who live alone and have limited social contact may not seek care promptly when complications arise.
Reduced motivation. Healing requires sustained effort over weeks or months. Patients with strong social connections have more external motivation to adhere to treatment.

Screening for Social Determinants in Wound Care

Standardized Screening Tools

Several validated tools screen for social determinants of health:

PRAPARE (Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences). A comprehensive 21-item screening tool developed by the National Association of Community Health Centers. Covers housing, food, transportation, social support, stress, and safety.
AHC HRSN (Accountable Health Communities Health-Related Social Needs). CMS-developed screening tool covering five core domains: housing instability, food insecurity, transportation, utility needs, and interpersonal safety.
Hunger Vital Sign. A two-item food insecurity screen validated for clinical settings: "Within the past 12 months, we worried whether our food would run out before we got money to buy more" and "Within the past 12 months, the food we bought just didn't last and we didn't have money to get more."

Integrating Screening Into Wound Care Workflow

Screen at intake and re-screen at regular intervals (every 90 days or when the patient's wound is not progressing as expected).
Assign a staff member to administer the screening — typically the medical assistant during rooming or a care coordinator.
Normalize the screening. Frame it universally: "We ask all our patients these questions because these factors affect healing."
Connect positive screens to action. Screening without follow-up is worse than not screening at all. Every positive screen should trigger a referral or resource connection.

Connecting Patients to Community Resources

Building a Resource Network

Wound care practices need an up-to-date directory of community resources organized by social need:

Food access:

Local food banks and food pantries.
Meals on Wheels and similar home-delivered meal programs.
SNAP (Supplemental Nutrition Assistance Program) enrollment assistance.
Medically tailored meal programs for patients with specific nutritional needs.

Housing:

Emergency shelter resources.
Housing assistance programs and Section 8 enrollment.
Home repair programs for patients with substandard housing.
Utility assistance programs (LIHEAP).

Transportation:

Medicaid Non-Emergency Medical Transportation (NEMT). Most Medicaid patients are entitled to transportation to medical appointments.
Local volunteer driver programs.
Subsidized rideshare programs for medical visits.
Telehealth as a partial substitute for in-person visits when clinically appropriate.

Social support:

Area Agency on Aging services for elderly patients.
Caregiver support groups and respite programs.
Mental health services and depression treatment.
Faith-based community support networks.

Making Referrals Actionable

A list of phone numbers is not a referral. Effective resource connection means:

Warm handoffs. When possible, make the call or submit the referral while the patient is still in the office.
Follow up. Check at the next visit whether the patient connected with the resource and what barriers they encountered.
Remove barriers to access. Help patients complete applications, provide documentation they need, and advocate on their behalf when bureaucratic obstacles arise.

For practical approaches to educating patients about self-management within their own constraints, see our guide on patient education materials for wound care.

Documenting Social Determinants in Wound Care

Why Documentation Matters

Documenting social determinants serves clinical, compliance, and reimbursement purposes:

ICD-10 Z codes allow coding for social determinants that affect care. Z59 codes cover housing issues, Z59.41-Z59.49 cover food insecurity, Z75.3 covers unavailability of healthcare facilities, and Z60 codes cover social isolation. Reporting these codes supports medical necessity for more intensive treatment, extended timelines, and additional services.
Clinical continuity. Documented social barriers ensure that every provider who sees the patient understands the non-clinical factors affecting healing.
Quality reporting. Aggregated social determinant data helps practices identify population-level needs and advocate for resources.

What to Document

Screening results (tool used, date, specific findings).
Referrals made (resource, date, contact method).
Referral outcomes (did the patient connect? what was provided?).
Impact on treatment plan (how social factors influenced clinical decisions).

Key Takeaways

Social determinants including housing, food access, transportation, and social isolation directly affect wound healing and may be the primary reason wounds fail to close despite appropriate clinical care.
Standardized screening tools like PRAPARE and AHC HRSN should be administered at intake and re-administered quarterly or when healing stalls, with positive screens triggering actionable referrals.
Building a community resource directory organized by social need and making warm-handoff referrals gives patients access to food programs, housing assistance, transportation, and social support that removes barriers to healing.
Document social determinants using ICD-10 Z codes to support medical necessity, ensure clinical continuity, and generate data that helps the practice advocate for resources.
Screening without follow-up is worse than not screening. Every identified social barrier must be connected to an action, tracked for resolution, and factored into the treatment plan.
