RESUMEN
BACKGROUND: Few studies have examined illness models among people with addiction. We investigated illness models and their associations with demographics and treatment beliefs among patients receiving methadone treatment for opioid use disorder. METHODS: From January 2019 to February 2020, patients receiving methadone treatment at outpatient opioid treatment programs provided demographics and rated using 1 to 7 Likert-type scales agreement with addiction illness models (brain disease model, chronic medical condition model [CMCM], and no explanation [NEM]) and treatment beliefs. Pairwise comparisons and multivariate regressions were used to examine associations between illness models, demographics, and treatment beliefs. Statistical significance was set at P < 0.05. RESULTS: A total of 450 patients participated in the study. Forty percent self-identified as female, 13% as Hispanic, and 78% as White; mean age was 38.5 years. Brain disease model was the most frequently endorsed illness model (46.2%), followed by CMCM (41.7%) and NEM (21.9%). In multivariate analyses, agreement with brain disease model was significantly positively associated with beliefs that methadone treatment would be effective, counseling is important, and methadone is lifesaving, whereas agreement with CMCM was significantly positively associated with beliefs that methadone treatment would be effective, counseling is important, 12-step is the best treatment, taking methadone daily is important, and methadone is lifesaving. In multivariate analyses, agreement with NEM was negatively significantly associated with beliefs that methadone would be effective, counseling is important, taking methadone daily is important, and methadone is lifesaving. DISCUSSION: Many patients in methadone treatment endorsed medicalized addiction models. Agreement with addiction illness models appear to be related to treatment beliefs.

BACKGROUND: Homelessness is an important social determinant of health (SDOH), impacting health outcomes for many medical conditions. Although homelessness is common among people with opioid use disorder (OUD), few studies systematically evaluate homelessness and other SDOH among people enrolled in standard of care treatment for OUD, medication for opioid use disorder (MOUD), or examine whether homelessness affects treatment engagement. METHODS: Using data from the 2016 to 2018 U.S. Treatment Episode Dataset Discharges (TEDS-D), patient demographic, social, and clinical characteristics were compared between episodes of outpatient MOUD where homelessness was reported at treatment enrollment versus independent housing using pairwise tests adjusted for multiple testing. A logistic regression model examined the relationship between homelessness and treatment length and treatment completion while accounting for covariates. RESULTS: There were 188 238 eligible treatment episodes. Homelessness was reported in 17 158 episodes (8.7%). In pairwise analysis, episodes involving homelessness were significantly different from those involving independent living on most demographic, social, and clinical characteristics, with significantly greater social vulnerability in most SDOH variables (P's < .05). Homelessness was significantly and negatively associated with treatment completion (coefficient = -0.0853, P < 0.001, 95% CI = [-0.114, -0.056], OR = 0.918) and remaining in treatment for greater than 180 days (coefficient = -0.3435, P < 0.001, 95% CI = [-0.371, -0.316], OR = 0.709) after accounting for covariates. CONCLUSIONS: Patients reporting homelessness at treatment entry in outpatient MOUD in the U.S. represent a clinically distinct and socially vulnerable population from those not reporting homelessness. Homelessness independently predicts poorer engagement in MOUD confirming that homelessness may be an independent predictor for MOUD treatment discontinuation nationally.

BACKGROUND: Despite recognition of the importance of substance use disorder (SUD) terminology, few studies examine terminology preferences among patients with SUDs. OBJECTIVE: To examine preferences of patients with opioid use disorder (OUD) concerning the terminology used by addiction counselors. DESIGN: From January 1, 2019, to February 28, 2020, participants were recruited consecutively from 30-day treatment review sessions at outpatient methadone treatment programs in the Northeastern United States to complete a cross-sectional survey. PARTICIPANTS: Participants were English-speaking adult patients with OUD enrolled in methadone treatment. MAIN MEASURES: Participants completed 7-point Likert-type scales from 1 ("Strongly Disagree") to 7 ("Strongly Agree") to rate their preferences for (a) the presenting problem, (b) collective nouns referring to those with the presenting problem, and (c) personal descriptors. We used univariate analysis of covariance (ANCOVA) to examine the associations between demographics (i.e., age, sex, and race) and terminology preferences and ordinal logit regression to explore the association between 12-step program partiality and preference for the term "addict." KEY RESULTS: We surveyed 450 patients with mean age of 38.5 (SD = 11.1) years; 59.6% self-identified as male, 77.6% as White, and 12.7% as Hispanic. The highest-rated preferences for presenting problem were "addiction," "substance use," and "substance abuse." The highest-rated collective noun terms were "client," "patient," and "guest." "Person with an addiction," "person with substance use disorder," and "substance-dependent person" were the highest-rated personal descriptors. There were significant differences in terminological preference based on race and age. Twelve-step program partiality was associated with greater preference for the term "addict" (F = 21.22, p < .001). CONCLUSIONS: Terminology preferences among people receiving methadone treatment aligned with existing guidelines recommending that clinicians use medically accurate and destigmatizing terminology when referring to substance use disorders and the persons who have them. Demographic differences emerged in terminological preferences, warranting further examination.

BACKGROUND: Few studies have directly compared patient characteristics and retention among those enrolled in methadone maintenance treatment (MMT) based on housing status. Low-barrier-to-treatment-access programs may be particularly effective at attracting patients experiencing homelessness into MMT; however, the literature on retention in such settings is limited. METHODS: We performed a retrospective chart review of 488 consecutive patients enrolled from April to October 2017 at low-barrier-to-treatment-access MMT programs in southern New England. Patients completed measures of demographics, social isolation, trauma, chronic pain, smoking behavior, and psychiatric distress. The study investigated associations between housing status and correlates with chi-square and Mann-Whitney U tests while controlling the False Discovery Rate. A two-sample log-rank test examined the relationship between retention and housing status. The study further scrutinized this association by regressing retention on all covariates using a Cox proportional hazards model. RESULTS: Forty-six patients (9.4%) reported experiencing homelessness and 442 (90.6%) reported being housed. Thirty-seven percent of patients self-identified as female and 20% as non-white. Compared to patients who were housed, those experiencing homelessness had lower rates of recent employment; higher rates of social isolation, trauma, current chronic pain, and recent cannabis use; and higher overall psychiatric distress (all p < 0.01). At one year, overall retention was 51.8%, and retention was 32.6% in the unhoused group and 53.8% in the housed group. A significant negative association occurred between retention and housing status (p = 0.006). After regressing on all covariates, homelessness was associated with a 69% increase in one-year treatment discontinuation (HR = 1.69 for homelessness, CI = 1.14-2.50). CONCLUSIONS: Patients entering MMT experiencing homelessness have multiple clinical vulnerabilities and are at increased risk for 12-month MMT discontinuation. Low-barrier-to-treatment-access MMT programs are an important venue for identifying and addressing vulnerabilities associated with homelessness.
