Aim: Comorbid drug and alcohol and mental health disorders are highly prevalent. Significant gaps in service provision make this problem particularly difficult to address in regional Australia. The Pathways to Comorbidity Care (PCC) program was designed to improve management of comorbidity by outpatient drug and alcohol clinicians in New South Wales, Australia. This paper uses the Consolidated Framework for Implementation Research (CFIR) to evaluate variations in implementation outcomes across geographically diverse services., Methods: Twenty clinicians across three drug and alcohol services from metropolitan, outer metropolitan and regional geographic locations were engaged at multiple levels of influence (directors, managers, clinicians) during the implementation of the multimodal PCC training package. The CFIR guided the development of self-report measures and semi-structured interviews evaluating implementation of the PCC training, and disparities in implementation barriers and facilitators were determined., Results: Metropolitan clinicians identified less barriers than regional clinicians on several intervention characteristics (adaptability, complexity, design quality and packaging), as well as outer setting (peer pressure), inner setting (implementation climate, staff incentives, leadership engagement, available resources) and process (planning, opinion leaders, executing) domains. Regional clinicians evaluated the networks and communications construct more favourably., Conclusions: Specific barriers identified more strongly by regional clinicians included the importance of communication with local clinicians and leadership about the practicalities of incorporating the approach into routine practice (allocation of time, increased accessibility of implementation team). Metropolitan clinicians provided more favourable evaluations of the package design, implementation climate and specific implementation processes such as a clear and informative implementation plan., (Copyright © 2022 JBI.

Background: Insomnia and excessive daytime sleepiness (EDS) are reported to be common in methadone maintenance treatment (MMT) but much less is known about these symptoms in buprenorphine maintenance treatment (BMT) and in women compared with men. Methods: Cross sectional study of recipients of BMT ( n  = 113, 47 women), MMT ( n  = 184, 94 women), people using opioids nonmedically (nonopioid agonist treatment, non-OAT: n  = 87, 31 women) and a reference group with no opioid use (RG; n  = 105, 53 women) in Australia. Measures included Athens Insomnia Scale, Epworth Sleepiness Scale, the Hospital Anxiety and Depression Scale, and other substance use. Results: Insomnia (Athens Insomnia Scale, total ≥10) was highly prevalent among all people who use opioids (BMT 46.0-68.1%; MMT 55.4-69.6%; non-OAT 58.6-80.5%), did not differ significantly among these groups, and was significantly associated with anxiety and depression. EDS (Epworth score >10) was found in 14.2% of BMT, 22.8% of MMT, 35.6% of non-OAT groups, and 11.4% of the RG, and was significantly associated with depression overall. Fewer people had Epworth score >15 indicating more severe EDS (BMT 4.4%, MMT 6.0%; non-OAT 13.8%; RG 1.9%). Insomnia and EDS did not differ by sex or by opioid dose, nor were they significantly associated with other drug use, housing stress or social security status. Conclusions: Insomnia was common in people receiving OAT and using opioids non-medically, and associated with anxiety and depression. Clinicians should consider the possibility of daytime sleepiness in people receiving BMT and MMT, and in people using opioids nonmedically.

Aim: to describe trends in baclofen reports to Australia's largest Poisons Information Centre (PIC) and present a case series detailing severity of overdoses., Short Summary: PBS data demonstrates baclofen use is increasing in Australia, while calls to NSWPIC illustrate an increase in number of exposures associated with toxicity. Baclofen toxicity may require prolonged intensive care admission. To minimize harms associated, especially with off-label baclofen prescribing for AUD, prescribers should pay careful attention to psychiatric comorbidities, and closely monitor treatment and dispensing., Methods: this is a retrospective observational study of baclofen overdoses reported to New South Wales PIC (NSWPIC) from January 1 2004 to 31 December 2016. In addition, referrals to a metropolitan toxicology service relating to baclofen toxicity from 2014 to 2017 were analysed. The number of Pharmaceutical Benefit Scheme (PBS) claims for baclofen were also reviewed., Results: during the 13-year study period, 403 cases of baclofen toxicity were reported to NSWPIC. There was a 230% increase in annual exposures over this period, 71% of patients were symptomatic, with 77% requiring hospitalization. Coingestants were reported in 53%, with 57% being psychoactive medications (including alcohol). An increase in number of baclofen dispensing episodes was also noted. From the five cases of deliberate self-harm reported to the metropolitan toxicology service, three obtained baclofen for management of alcohol use disorder (AUD) and required prolonged treatment in the intensive care unit (ICU)., Conclusions: NSWPIC data shows an increase in number of calls regarding intentional baclofen exposures in parallel with increase the number of baclofen PBS claims. These closely parallel the increase in dispensing of baclofen since 2008. Case studies presented reinforce the severity of baclofen toxicity. Together, they demonstrate the potential risk of harm of baclofen prescribing, and the greater need for caution. Baclofen should be considered carefully in patients high risk of overdose or be used only in specialist services with close monitoring.

Objective: Comorbid mental health and substance use problems are highly prevalent in substance use treatment settings and generally lead to poorer treatment outcomes. Pathways to Comorbidity Care (PCC) is a multimodal training program developed to encourage an integrated service approach to improve clinicians capacity to identify and manage comorbid substance use and mental health outcomes within public drug and alcohol treatment settings., Methods: In this paper we describe the concepts underlying the PCC package and the use of implementation science to assess and overcome potential barriers, including clinicians preferences, knowledge about best practice, and professional culture., Results: The training components include didactic seminars, group workshops run by a local clinical champion on relevant subjects such as motivational interviewing and cognitive behavioral therapy, individual clinical consultation, and feedback with a senior clinical psychologist. The PCC also includes an online portal containing comorbidity resources including manuals, guidelines, and booster webinars. Finally, we describe the evaluation of PCC implementation., Conclusions: Drug and alcohol services need to be equipped to treat the majority of comorbid mental health conditions in their clients. We anticipate that this multimodal training package, which applies the principles of implementation science, will facilitate effective and integrated care for these vulnerable clients.
