Sample
Between 8/20/20-8/23/21, we approached all scheduled patients seen in a single, hospital-based primary care clinic for annual or employment examinations to ascertain interest in the study. Patients were approached by a medical assistant or physician who described the study using a prepared script. Potential participants were asked during a telemedicine or in-person appointment if they would be interested in participating in a study about “what it takes to be healthy and the role of housing, food security, medical transportation, utilities (heat, light, water), and personal safety.” Patients expressing interest provided contact information. The research team then followed up by telephone and email contact and obtained consent. The study was approved by the University of Pittsburgh Human Research Protections Office.
The clinic is based at a university hospital and serves a diverse patient population, including unversity faculty and staff, hospital employees, and community members. It includes a residency program and sees patients with a variety of insurance coverage, including Medicaid.
Design
Participants were invited to complete the AHC Health-Related Social Needs Screening (HRSN) a single time within 1-2 weeks of their clinic visits. We used the expanded questionnaire developed by the Social Interventions Research & Evaluation Network (SIREN).14 Patients were paired with research assistants who followed up with potential participants to encourage completion of social needs screening either through an Internet survey sent via email or by telephone interview. Patient responses were de-identified and not linked to the EHR.
Measures
To measure social needs, patients completed the Accountable Health Communities (AHC) Health-Related Social Needs Screening Tool.4 CMS developed the 10-item screening tool to identify patient needs that can be addressed through community services. The measure assesses five domains (housing instability, food insecurity, transportation difficulties, utility assistance needs, and interpersonal safety).
The AHC HRSN can be scored in a variety of ways to indicate social needs. We used the following thresholds: Unstable housing: 1+ problem (pests, mold, lead, heat, oven, no smoke detector, water leak) or unstable housing (anxious about losing home or homeless). Food insecurity: Sometimes/often run out of food or food does not last until end of month. Transportation need: Lack of reliable transportation. Intermittent utilities: utilities shut off in past year. Threat to safety: Worried about safety, threatened with harm, or sometimes/often screamed at or cursed. We computed a sum for the number of social needs reported (range, 0-5).
We included a number of additional measures used in the SIREN study.14 These elicit additional information on the five domains of social need as well as patient experience answering these questions: have they been asked the questions in the prior 12 months, have they received assistance with any of the needs, do they think it is appropriate to be asked such questions, and “would you be comfortable having these kinds of needs included in your health records (also known as your medical record or chart).” Other questions elicited a rating of health, trust in your health care provider (1-10 scale), and “where you see yourself in relation to others in the United States” (1, worst off-10, very top). Patients were also asked if they experienced disrespect from health care providers using the SIREN 6-point index. Finally, patients reported sociodemographic information, including income categories (13-point scale ranging from <$5,000 to >=$150,000). The questionnaire is available as a supplement to the SIREN study: https://www.ajpmonline.org/cms/10.1016/j.amepre.2019.07.010/attachment/f00500c1-4267-4be7-b089-f01328d38471/mmc1.pdf.
Analyses
Analyses were mainly descriptive and sought to characterize the level and type of social needs reported by the sample along with additional indicators, including whether patients were asked about each need in clinic visits, how comfortable they were with this line of questioning, whether they wanted assistance with the need, and whether they received assistance.
We compared means by t-test and computed Pearson and Spearman correlations. To assess the relationship between social needs and comfort with recording such information in the EHR, we estimated linear and ordinal regression models that adjusted for these factors to identify how much comfort with EHR documentation changed with each additional reported social need. Analyses were conducted using STATA/SE 15.1.
