Pivoting from in-person to phone survey assessment of alcohol and substance use: effects on representativeness in a United States prospective cohort of women living with and without HIV.

Background: Many clinical and population-based research studies pivoted from in-person assessments to phone-based surveys due to the COVID-19 pandemic. The impact of these transitions on survey response remains understudied, especially for people living with HIV. Given that there are gender-specific trends in alcohol and substance use, it is particularly important to capture these data for women.Objective: Identify factors associated with responding to an alcohol and substance use phone survey administered during the COVID-19 pandemic in the Women's Interagency HIV Study, a multicenter US prospective cohort of women living with and without HIV.Methods: We used multivariable logistic regression to assess for associations of pre-pandemic (April-September 2019) sociodemographic factors, HIV status, housing status, depressive symptoms, alcohol use, and substance use with response to an early-pandemic (August-September 2020) phone survey.Results: Of 1,847 women who attended an in-person visit in 2019, 78% responded to a phone survey during the pandemic. The odds of responding were lower for women of Hispanic ethnicity (aOR 0.47 95% CI 0.33-0.66, ref=Black/African American) and those who reported substance use (aOR 0.63 95% CI 0.41-0.98). By contrast, the odds were higher for White women (aOR 1.64 95% CI 1.02-2.70, ref=Black/African American) and those with stable housing (aOR 1.74 95% CI 1.24-2.43).Conclusions: Pivoting from an in-person to phone-administered alcohol and substance use survey may lead to underrepresentation of key subpopulations of women who are often neglected in substance use and HIV research. As remote survey methods become more common, investigators need to ensure that the study population is representative of the target population.

Predictors of Linkage to an Opioid Treatment Program and Methadone Treatment Retention following Hospital Discharge in a Safety-Net Setting.

Background: Methadone is increasingly initiated during hospitalization for the treatment of opioid use disorder (OUD). However, little is known about which factors are associated with linkage to opioid treatment programs (OTP) and retention in methadone maintenance therapy (MMT) following hospital discharge. Materials & Methods: This is a retrospective study of adults with OUD hospitalized in an urban, safety-net hospital referred by inpatient clinicians to an onsite OTP for post-discharge MMT follow-up from October 2017 to July 2019. We used multivariable modified Poisson regression models to generate adjusted risk ratios (aRR) for associations of sociodemographic factors, mental health disorders, alcohol use, stimulant use, and prior care engagement with post-discharge OTP enrollment and MMT retention at 30 and 90-days. Results: Of the 125 patients referred, 40% enrolled in the OTP post-discharge. Among enrollees, 74% were retained at 30-days and 52% were retained at 90-days. Patients with co-occurring stimulant use were less likely to enroll in the OTP post-discharge compared to those without stimulant use (aRR 0.65, 95% CI 0.44-0.97). We found no associations with 30-day MMT retention, but patients who reported stable housing were more likely to be retained in MMT at 90-days compared to those without stable housing (aRR 1.66, 95% CI 1.03-2.66). Conclusion: Our findings suggest that hospitalized patients with co-occurring stimulant use may need additional support to optimize post-discharge OTP linkage. Stable housing may improve retention in MMT. Additional research is needed to identify trends in MMT engagement among those referred from the acute hospital setting.

Assessing Student Readiness to Work with People Who Use Drugs: Development of a Multi-disciplinary Addiction Educational Survey.

BACKGROUND: As health profession schools implement addiction curricula, they need survey instruments to evaluate the impact of the educational interventions. However, existing measures do not use current non-stigmatizing language and fail to capture core concepts. OBJECTIVE: To develop a brief measure of health profession student readiness to work with people who use drugs (PWUDs) and establish its content validity. METHODS: We conducted a literature review of existing instruments and desired clinical competencies related to providing care to PWUD and used results and expert feedback to create and revise a pool of 72 items. We conducted cognitive interviews with ten pre-clinical health profession students from various US schools of nursing, pharmacy, and medicine to ensure the items were easy to understand. Finally, we used a modified Delphi process with twenty-four health professions educators and addiction experts (eight each from nursing, pharmacy, and medicine) to select items for inclusion in the final scale. We analyzed expert ratings of individual items and interdisciplinary agreement on ratings to decide how to prioritize items. We ultimately selected 12 attitudes and 12 confidence items to include in the REadiness to Discuss Use, Common Effects, and HArm Reduction Measure (REDUCE-HARM). Experts rated their overall assessment of the final scale. RESULTS: Twenty-two of twenty-four experts agreed or strongly agreed that the attitudes scale measures student attitudes that impact readiness to work with PWUDs. Twenty-three of twenty-four experts agreed or strongly agreed that the confidence scale measures student self-efficacy in competencies that impact readiness to work with PWUDs. Seven of 72 initial items and none of the 24 selected items had statistically significant differences between disciplines. CONCLUSIONS: The REDUCE-HARM instrument has strong content validity and may serve as a useful tool in evaluating addiction education. Additional research is needed to establish its reliability, construct validity, and responsiveness to change.

Inpatient Opioid Use Disorder Treatment by Generalists is Associated With Linkage to Opioid Treatment Programs After Discharge.

OBJECTIVES: Describe clinical and demographic associations with inpatient medication for opioid use disorder (MOUD) initiation on general medicine services and to examine associations between inpatient MOUD initiation by generalists and subsequent patient healthcare utilization. METHODS: This is a retrospective study using medical record data from general medicine services at an urban safety-net hospital before an inpatient addiction consultation service. The patients were adults hospitalized for acute medical illness who had an opioid-related ICD-10 code associated with the visit. Associations with MOUD initiation were assessed using multivariable logistic regression. Hospital readmission, emergency department use, linkage to opioid treatment programs (OTP), and mortality at 30- and 90-days postdischarge were compared between those with and without hospital MOUD initiation using χ2 tests. RESULTS: Of 1,284 hospitalized patients with an opioid-related code, 59.81% received MOUD and 31.38% of these were newly initiated in-hospital. In multivariable logistic regression, Black race, mood disorder, psychotic disorder, and alcohol use disorder were negatively associated with MOUD initiation, while being aged 25-34, having a moderate hospital severity of illness score, and experiencing homelessness were positively associated. There were no bivariate associations between MOUD initiation and postdischarge emergency department use, hospital readmission, or mortality at 30- and 90-days, but those initiated on MOUD were more likely to present to an OTP within 90 days (30.57% vs 12.80%, P < 0.001). CONCLUSIONS: MOUD prescribing by inpatient generalists may help to increase the number of patients on treatment for opioid use disorder after hospital discharge. More research is needed to understand the impact of inpatient MOUD treatment without addiction specialty consultation.

Methadone treatment and patient-directed hospital discharges among patients with opioid use disorder: Observations from general medicine services at an urban, safety-net hospital.

Introduction: People with opioid use disorder (OUD) have high rates of discharge against medical advice from the hospital. Interventions for addressing these patient-directed discharges (PDDs) are lacking. We sought to explore the impact of methadone treatment for OUD on PDD. Methods: Using electronic record and billing data from an urban safety-net hospital, we retrospectively examined the first hospitalization on a general medicine service for adults with OUD from January 2016 through June 2018. Associations with PDD compared to planned discharge were examined using multivariable logistic regression. Administration patterns of maintenance therapy versus new in-hospital initiation of methadone were examined using bivariate tests. Results: During the study time period, 1,195 patients with OUD were hospitalized. 60.6% of patients received medication for OUD, of which 92.8% was methadone. Patients who received no treatment for OUD had a 19.1% PDD rate while patients initiated on methadone in-hospital had a 20.5% PDD rate and patients on maintenance methadone during the hospitalization had a 8.6% PDD rate. In multivariable logistic regression, methadone maintenance was associated with lower odds of PDD compared to no treatment (aOR 0.53, 95% CI 0.34-0.81), while methadone initiation was not (aOR 0.89, 95% CI 0.56-1.39). About 60% of patients initiated on methadone received 30 mg or less per day. Conclusions: In this study sample, maintenance methadone was associated with nearly a 50% reduction in the odds of PDD. More research is needed to assess the impact of higher hospital methadone initiation dosing on PDD and if there is an optimal protective dose.
