Effects of Telehealth on Dropout and Retention in Care among Treatment-Seeking Individuals with Substance Use Disorder: A Retrospective Cohort Study.

Background: During the COVID-19 pandemic, telehealth became a widely used method of delivering treatment for substance use disorders (SUD), but its impact upon treatment engagement and dropout remains unknown. Methods: We conducted a retrospective analysis of adult SUD patients (n = 544) between October 2020 and June 2022 among a cohort of treatment-seeking patients at a nonprofit community behavioral health center in Southwestern Ohio. We estimated the likelihood of treatment dropout using survival curves and Cox proportional hazard models, comparing patients who used telehealth with video, telephone, or solely in-person services within the first 14 days of diagnosis. We also compared the likelihood of early treatment engagement. Results: Patients who received services through telehealth with video in the initial 14 days of diagnosis had a lower hazard of dropout, compared to patients receiving solely in-person services (0.64, 95% CI [0.46, 0.90]), while there was no difference in hazards of dropout between patients who received telephone and in-person services. Early use of telehealth, both via video (5.40, 95% CI [1.92, 15.20]) and telephone (2.12, 95% CI [1.05, 4.28]), was associated with greater odds of treatment engagement compared to in-person care. Conclusion: This study adds to the existing literature related to telehealth utilization and engagement in care and supports the inclusion of telehealth in SUD treatment programs for treatment-seeking individuals.

Exploring the Interactions between Non-Medical Methamphetamine Use and Prescribed Buprenorphine or Naltrexone in Opioid Use Disorder Treatment Retention.

OBJECTIVES: Our objectives were to examine the impact of methamphetamine use on opioid use disorder (OUD) treatment retention in patients prescribed either buprenorphine/buprenorphine-naloxone (BUP-NX) or naltrexone/extended-release naltrexone (XR-NTX), while also exploring the role of other risk factors that may modify the impact of methamphetamine use. METHODS: We conducted an exploratory retrospective study examining OUD treatment retention in 127 patients in Ohio (USA). Patients were prescribed either BUP-NX or naltrexone/XR-NTX. Cox proportional hazard regression was used to compare time to dropout of treatment between patients positive and negative on screening for methamphetamines at intake, estimate the association between other risk factors and time to dropout, and test interactions between risk factors and methamphetamine status. RESULTS: Among patients prescribed naltrexone/XR-NTX, those positive for methamphetamines had almost three times the risk of treatment dropout (AHR = 2.89, 95% CI =1.11, 7.07), significantly greater (interaction p = .039) than the methamphetamine effect among those prescribed BUP-NX (AHR = 0.94, 95% CI = 0.51, 1.65). Early in treatment, being prescribed BUP-NX was strongly associated with a greater risk of treatment dropout (at baseline: AHR = 2.90, 95% CI = 1.33, 7.15), regardless of baseline methamphetamine use status. However, this effect decreased with time and shifted to greater risk of dropout among those prescribed naltrexone/XR-NTX (non-proportional hazard; interaction with time AHR = 0.66, 95% CI = 0.49, 0.86), with the shift occurring sooner among those positive for methamphetamine at baseline. CONCLUSIONS: Additional support should be provided to patients who use methamphetamines prior to starting OUD treatment.

Association Between Proportion of Workday Treating COVID-19 and Depression, Anxiety, and PTSD Outcomes in US Physicians.

OBJECTIVE: The primary objective of this cross-sectional study was to examine the association between time spent treating patients with Coronavirus disease 2019 (COVID-19) and levels of depression, anxiety, and posttraumatic stress disorder (PTSD) in US physicians. METHODS: The authors conducted an anonymous online survey of US physicians. Linear regression was used to test the association between proportion of day treating COVID-19 and symptoms of depression, anxiety, and PTSD. RESULTS: In a sample of 1724 US physicians, proportion of day treating COVID-19 was positively and significantly associated with depression, anxiety, and PTSD scores (P < 0.001 for each). CONCLUSIONS: Mental health resources should be provided to physicians who treat COVID-19 because the proportion of day treating COVID-19 is associated with depression, anxiety, and PTSD outcomes.

The relationship between dissociative symptoms and the medications used in the treatment of opioid use disorder.

Opioid use disorder has long been associated with psychiatric symptoms, including dissociative experiences. Medications used to treat opioid use disorder can potentially impact dissociative symptoms, but the existing literature has not explored this. We examined the relationship between dissociative symptoms and opioid use disorder using the Dissociative Experiences Scale (DES). We studied subjects who were taking prescribed methadone, buprenorphine, or naltrexone for opioid use disorder. We gave the DES, the Patient Health Questionairre-9 (PHQ-9), and the PTSD Checklist for DSM-5 (PCL-5) with Criterion A to subjects in three substance use treatment facilities in Ohio. We conducted Analysis of Variance (ANOVA) and Spearman's Rank Correlations to examine associations between the variables and outcomes. We developed three separate multiple linear regression models. We included 116 participants in our exploratory and naturalistic study. The majority of participants were female (51.7%), white (89.5%), ≤ 40 years of age (64.7%), and taking buprenorphine (55%). The average DES score was 16.1 (standard deviation = 14.9) and we considered 80.9% to have low dissociation (score < 30). Approximately 55% (n = 64) of participants were taking prescribed buprenorphine. Approximately 27% (n = 32) were taking prescribed methadone and approximately 18% (n = 21) were taking prescribed naltrexone (oral or extended release). There was a significant association between opioid medication type and log dissociative symptoms (p = .01). Participants taking prescribed buprenorphine had higher mean log dissociation symptom scores (2.7) compared to those taking prescribed methadone (2.2) and prescribed naltrexone (2.1). Log dissociation symptom scores were significantly associated with last use of any opiates (rs = -0.21; p = .02) and time on medication (rs = -0.228; p = .01). Compared to those taking buprenorphine, those taking both methadone (ß = -0.26; p = .01) and naltrexone (ß = -0.27; p = .006) had significantly lower dissociation scores, controlling for the other variables in the model. Dissociation scores were positively correlated with depression scores (r = 0.45; p < .0001) and with PCL-5 scores (r = 0.51; p < .0001). Our study highlights the importance of diagnosing and monitoring dissociative symptoms in individuals who are taking prescribed medications for opioid use disorder, especially since dissociative symptoms can interfere with substance use treatment.
