Addressing Social Vulnerabilities in Cardiovascular Disease

August 28, 2025 updated by: University of California, San Francisco

Addressing Social Vulnerabilities to Prevent Hospital Readmissions in Adults With Cardiovascular Disease

The investigators will conduct a feasibility study of an enhanced transitional care intervention, that will: 1) automate identification and risk-stratification of patients with CHF and IHD with social vulnerabilities; 2) incorporate a new standardized social vulnerabilities screening tool into clinical care; 3) enable electronic referrals to community resources; and 4) add novel community-based interventions to the existing medically-oriented transitional care intervention that is the standard of care at the study hospital (Parkland Hospital in Dallas, Texas) and other hospitals nationwide.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators plan to develop, pilot and evaluate the feasibility of an existing medically oriented transitional care intervention enhanced to also address social vulnerabilities, to prevent readmissions in congestive heart failure (CHF) & ischemic heart disease (IHD). The intervention design will be based on the Andersen Behavior Model of Health Services Use, highlighting pathways for clinical linkages to community resources to facilitate individual behavior change. To summarize, although existing interventions have largely focused on individual- and health system-level factors such as optimizing medication regimens, discharge education, and post-discharge follow-up, much of the risk for readmission in patients with CHF and IHD is also driven by social vulnerabilities that are currently not addressed in medical settings. Community-based organizations are a valuable but untapped resource to ameliorate key social vulnerabilities (i.e., food/housing insecurity, behavioral health needs) that are major barriers to effective medication and visit adherence, self-management and lifestyle modification in patients with heart disease. Thus, the investigators propose an enhanced transitional care intervention that uses the Dallas Information Exchange Portal, a health information technology platform, to link patients to local community organizations at discharge. Addressing social vulnerabilities to enable better adherence, self-management, and lifestyle behaviors can in turn prevent readmissions and improve downstream health outcomes. The investigators will conduct a feasibility study of an enhanced transitional care intervention, that will: 1) automate identification and risk-stratification of patients with CHF and IHD with social vulnerabilities; 2) incorporate a new standardized social vulnerabilities screening tool into clinical care; 3) enable electronic referrals to community resources; and 4) add novel community-based interventions to the existing medically-oriented transitional care intervention that is the standard of care at Parkland and other hospitals nationwide. The investigators will assess feasibility and acceptability of our intervention using measures derived from the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) implementation science framework.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Congestive Heart Failure (CHF)
The CHF arm will include adults hospitalized with CHF who have been identified as being at high risk for readmission (in the top quintile of risk) by our readmission risk prediction algorithms, and who also have social vulnerabilities present. All subjects in the CHF arm will receive the Socially Enhanced Transitional Care Intervention.
Other: Socially Enhanced Transitional Care Intervention
Components: 1) Standardized social vulnerabilities assessment tool, to be developed and incorporated into admission workflows. 2) Electronic community service referrals to existing community resources (i.e. food banks, shelters, community rehab), via the Dallas IEP or other information technology platform, for material (food, housing) and psychosocial needs (mental health/drug treatment). 3) Community-based cardiovascular self-management interventions, to be developed and piloted in conjunction with #3 - e.g., customized 'heart healthy' food baskets for CHF/IHD; risk factor monitoring (i.e., weight and blood pressure measurement at food banks, shelters, churches, modeled on the barber shop hypertension intervention); and 'heart buddy' support groups for CHF and IHD at community sites.
Experimental: Ischemic Heart Disease (IHD)
The IHD arm will include adults hospitalized with IHD who have been identified as being at high risk for readmission (in the top quintile of risk) by our readmission risk prediction algorithms, and who also have social vulnerabilities present. All subjects in the IHD arm will receive the Socially Enhanced Transitional Care Intervention.
