Commentary on Lin et al.: Saving lives during the opioid crisis-widening the focus from opioid use disorder to polysubstance use disorder and to multimorbidity

Impact of an intervention to implement provision of opioid use disorder medication among patients with and without co-occurring substance use disorders

INTRODUCTION

Co-occurring substance use disorders (SUDs) are common among people with opioid use disorder (OUD) and known to hinder receipt of medications for OUD (MOUD). It is important to understand how MOUD care implemented outside of SUD specialty settings impacts access for patients with co-occurring SUDs. The Veterans Health Administration's (VA) Stepped Care for Opioid Use Disorder Train the Trainer (SCOUTT) initiative was implemented in primary care, mental health, and pain clinics in 18 VA facilities, and was found to increase MOUD receipt. This study assessed the SCOUTT initiative's impact among patients with and without co-occurring SUDs.

METHODS

This study used a controlled interrupted time series design. We extracted electronic health record data for patients with OUD with visits in SCOUTT intervention or matched comparison clinics during the post-implementation year (9/1/2018-8/31/2019). We examined the monthly proportion of patients who received MOUD in SCOUTT intervention or comparison clinics (primary care, mental health, and pain clinics), or in a VA SUD specialty clinic (where patients may have been referred), during the pre- and post-implementation years. Segmented logistic regression models estimated pre-post changes in outcomes (immediate level change from the final month of the pre-implementation period to the first month of the post-implementation period, change in trend/slope) in intervention vs. comparison facilities, adjusting for patient characteristics and pre-implementation trends. We stratified analyses by the presence of co-occurring SUDs.

RESULTS

Among patients without co-occurring SUDs, the pre-post trend/slope change in MOUD received in SCOUTT intervention or comparison clinics was greater in intervention vs. comparison facilities (adjusted odds ratio [aOR]: 1.06, 95% confidence interval [CI]: 1.02-1.10), and the immediate increase in MOUD received in SUD clinics was greater in intervention vs. comparison facilities (aOR: 1.12, 95% CI: 1.02-1.22). These changes did not significantly differ in intervention vs. comparison facilities among patients with co-occurring SUDs.

CONCLUSIONS

The SCOUTT initiative may have increased MOUD receipt primarily among patients without co-occurring SUDs. Focusing on increasing MOUD receipt for patients with co-occurring SUDs may improve the overall effectiveness of MOUD implementation efforts.

Treating opioid use disorder in veterans with co-occurring substance use: a qualitative study with buprenorphine providers in primary care, mental health, and pain settings

BACKGROUND

Most people with opioid use disorder (OUD) have co-occurring substance use, which is associated with lower receipt of OUD medications (MOUD). Expanding MOUD provision and care linkage outside of substance use disorder (SUD) specialty settings is a key strategy to increase access. Therefore, it is important to understand how MOUD providers in these settings approach care for patients with co-occurring substance use. This qualitative study of Veterans Health Administration (VA) clinicians providing buprenorphine care in primary care, mental health, and pain settings aimed to understand (1) their approach to addressing OUD in patients with co-occurring substance use, (2) perspectives on barriers/facilitators to MOUD receipt for this population, and (3) support needed to increase MOUD receipt for this population.

METHODS

We interviewed a purposive sample of 27 clinicians (12 primary care, 7 mental health, 4 pain, 4 pharmacists) in the VA northwest network. The interview guide assessed domains of the Tailored Implementation for Chronic Diseases Checklist. Interviews were transcribed and qualitatively analyzed using inductive content analysis.

RESULTS

Participants reported varied approaches to identifying co-occurring substance use and addressing OUD in this patient population. Although they reported that this topic was not clearly addressed in clinical guidelines or training, participants generally felt that patients with co-occurring substance use should receive MOUD. Some viewed their primary role as providing this care, others as facilitating linkage to OUD care in SUD specialty settings. Participants reported multiple barriers and facilitators to providing buprenorphine care to patients with co-occurring substance use and linking them to SUD specialty care, including provider, patient, organizational, and external factors.

CONCLUSIONS

Efforts are needed to support clinicians outside of SUD specialty settings in providing buprenorphine care to patients with co-occurring substance use. These could include clearer guidelines and policies, more specific training, and increased care integration or cross-disciplinary collaboration. Simultaneously, efforts are needed to improve linkage to specialty SUD care for patients who would benefit from and are willing to receive this care, which could include increased service availability and improved referral/hand-off processes. These efforts may increase MOUD receipt and improve OUD care quality for patients with co-occurring substance use.

Sex Differences in Opioid Use Disorder Prevalence and Multimorbidity Nationally in the Veterans Health Administration

Opioid use disorder (OUD) is a significant problem among US veterans with increasing rates of OUD and overdose, and thus has substantial importance for service delivery within the Veterans Health Administration (VHA). Among individuals with OUD, several sex- specific differences have begun to emerge regarding co-occurring medical, psychiatric and pain-related diagnoses. The rates of such multimorbidities are likely to vary between men and women with OUD and may have important implications for treatment within the VHA but have not yet been studied. Methods: The present study utilized a data set that included all veterans receiving VHA health care during Fiscal Year (FY) 2012 (October 1, 2011 through September 30, 2012), who were diagnosed during the year with opioid dependence or abuse. VHA patients diagnosed with OUD nationwide in FY 2012 were compared by sex on proportions with OUD, and among those with OUD, on sociodemographic characteristics, medical, psychiatric and pain-related diagnoses, as well as on service use, and psychotropic and opioid agonist prescription fills. Results: During FY 2012, 48,408 veterans were diagnosed with OUD, 5.77% of whom were women. Among those veterans with OUD, few sociodemographic differences were observed between sexes. Female veterans had a higher rate of psychiatric diagnoses, notably mood, anxiety and personality disorders, as well as higher rates of pain-related diagnoses, such as headaches and fibromyalgia, while male veterans were more likely to have concurrent, severe medical co-morbidities, including hepatic disease, HIV, cancers, peripheral vascular disease, diabetes and related complications, and renal disease. There were few differences in health service utilization, with women reporting greater receipt of prescriptions for anxiolytic/sedative/hypnotics, stimulants and lithium. Men and women did not differ in receipt of opioid agonist medications or mental health/substance use treatments. Conclusions: There are substantial sex-specific differences in patterns of multimorbidity among veterans with OUD, spanning medical, psychiatric and pain-related diagnoses. These results illustrate the need to view OUD as a multimorbid condition and design interventions to target such multimorbidities. The present study highlights the potential benefits of sex-specific treatment and prevention efforts among female veterans with OUD and related co-occurring disorders.

Patient Perspectives on Detox: Practical and Personal Considerations through a Lens of Patient-Centered Care

Inpatient detoxification is often required before a client can move on to additional substance abuse treatment services. Although often short-term, time spent in inpatient detoxification tends to have long-lasting effects on the recovery process. This qualitative study focuses on one treatment facility in Tampa, Florida that offers a range of recovery services, including inpatient detox and outpatient treatment. Focus groups (N = 70 participants) captured client perceptions of direct clinical care operations, access to resources, and relationships with direct care staff within the inpatient detox program. Perceptions were then assessed using a thematic analysis approach with attention to the literature on person-centered care best practices, behavior change, and patient engagement theories to better understand how facility practices affect treatment engagement and retention. Findings elucidated several practical facilitators and barriers to recovery such as facility resources, services offered, transition to aftercare, and sustainability of treatment. Findings also illuminated several personal facilitators and barriers including patient-staff interactions, personal motivation, and family and community support. The resulting recommendations for practice and research are discussed.
