Persons living with mental illness, substance use disorder, and medical conditions, or “tri-morbidity,” have complex health needs. Tri-morbidity may be common among those who are homeless, and who face considerable obstacles to obtaining the high-quality, patient-centered health care and strong social support they need.
Tri-morbidity was operationalized as meeting the following criteria: 1) probable mental illness or major psychiatric distress, based on reporting a diagnosis of post-traumatic stress disorder or schizophrenia, having ever taken psychiatric medication for a significant period of time, or a score of 30+ on the Colorado Symptom Index (range: 5–70) ; 2) lifetime moderate- or high-risk alcohol or illicit drug use, as measured using the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) v. 3 ; and 3) reporting at least 1 of 14 physician-diagnosed chronic medical conditions.
Primary care experience was measured using the Primary Care Quality-Homeless (PCQ-H) tool (range: 1–4) . Social support was measured using the "strong ties" scale (range: 3–15) , which queries the degree to which persons are bothered by not having a close companion, enough friendships, or people to whom they feel close.
Patients (N = 601) from five geographically diverse primary care sites (four from the Department of Veterans Affairs [VA] and one health care for homeless program) were surveyed. Pearson’s chi-square, correlations, and t-tests assessed bivariate relationships. Multiple linear regression tested whether tri-morbidity predicted lower social support, compared to those without tri-morbidity, controlling for characteristics associated with strong ties.

Tri-morbidity was common in this sample of primary care-engaged formerly and currently homeless persons. Despite their increased complexity, the patient-reported primary care experience was not worse in the presence of tri-morbidity. Their lower social support, even compared to other homeless-experienced patients, might be relevant for primary care providers’ treatment plans.
