Abstract
PURPOSE OF REVIEW Precision medicine prioritizes characterization of individual patient parameters to optimize care and this review evaluates measurement-based care (MBC) as a strategy for doing so in the treatment of substance use disorders (SUD). Measurement-based care refers to the systematic use of validated assessments to inform diagnosis and treatment planning, with varying frequency of assessments. Despite the seemingly obvious grounds for the use of MBC in treating SUD, systematic implementation to date has been limited. Thus, the goal of this review is to evaluate efforts to date and to stimulate greater consideration of MBC models in addictions programs. RECENT FINDINGS Data from two published randomized controlled trials and findings from pragmatic clinical research highlight the potential utility of MBC in the SUD treatment settings. Despite these findings, the existing literature indicates the high need for larger-scale clinical trials and quality improvement programs. Potential barriers to the implementation of MBC for SUD are outlined at the patient, provider, organization, and system levels, as well as the challenges associated with the use of MBC programs for clinical research. Critical thinking considerations and risk mitigation strategies are offered toward advancing MBC for SUD beyond the current nascent state. Collectively, the existing data confirm that MBC is a suitable and promising strategy for applying a precision medicine approach in SUD treatment, warranting further implementation efforts and scientific inquiry.

The independent and combined impact of moral injury and moral distress on post-traumatic stress disorder symptoms among healthcare workers during the COVID-19 pandemic. Eur J Psychotraumatol 2024; 15:2299661. [PMID: 38334706 PMCID: PMC10860446 DOI: 10.1080/20008066.2023.2299661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 12/04/2023] [Indexed: 02/10/2024] Open
Abstract
Background: Healthcare workers (HCWs) across the globe have reported symptoms of Post-Traumatic Stress Disorder (PTSD) during the COVID-19 pandemic. Moral Injury (MI) has been associated with PTSD in military populations, but is not well studied in healthcare contexts. Moral Distress (MD), a related concept, may enhance understandings of MI and its relation to PTSD among HCWs. This study examined the independent and combined impact of MI and MD on PTSD symptoms in Canadian HCWs during the pandemic.Methods: HCWs participated in an online survey between February and December 2021, with questions regarding sociodemographics, mental health and trauma history (e.g. MI, MD, PTSD, dissociation, depression, anxiety, stress, childhood adversity). Structural equation modelling was used to analyze the independent and combined impact of MI and MD on PTSD symptoms (including dissociation) among the sample when controlling for sex, age, depression, anxiety, stress, and childhood adversity.Results: A structural equation model independently regressing both MI and MD onto PTSD accounted for 74.4% of the variance in PTSD symptoms. Here, MI was strongly and significantly associated with PTSD symptoms (β = .412, p < .0001) to a higher degree than MD (β = .187, p < .0001), after controlling for age, sex, depression, anxiety, stress and childhood adversity. A model regressing a combined MD and MI construct onto PTSD predicted approximately 87% of the variance in PTSD symptoms (r2 = .87, p < .0001), with MD/MI strongly and significantly associated with PTSD (β = .813, p < .0001), after controlling for age, sex, depression, anxiety, stress, and childhood adversity.Conclusion: Our results support a relation between MI and PTSD among HCWs and suggest that a combined MD and MI construct is most strongly associated with PTSD symptoms. Further research is needed better understand the mechanisms through which MD/MI are associated with PTSD.

Abstract
Indigenous individuals in Canada disproportionally experience higher rates of substance use concerns. This study examined clinical practices currently implemented with Indigenous-led residential treatment facilities to simultaneously address substance use and post-traumatic stress. A systematic review of relevant literature retrieved published approaches to address these concurrent disorders with Indigenous individuals. This review retrieved 35 sources related to trauma and substance use treatment among Indigenous individuals or communities. Among these sources, all leveraged cultural approaches as a dual treatment for trauma symptoms and substance use. Inconsistent results were reported among those sources (n = 3) who analyzed comparisons with wait-list controls or used randomized-controlled designs. Using culture-as-treatment was elaborated upon in the second goal of this study: an environmental scan of Indigenous-led treatment programs and qualitative interviews with 10 treatment center staff to understand how programs may address both substance use and traumatic symptoms among Indigenous-led substance use treatment centers across Canada. When we searched the websites of these centers, we found that approximately 38% (16 of 43) of treatment centers discussed implementing some form of treatment that addressed trauma symptoms in conjunction with primary substance use. Among the 10 staff participants, all discussed how trauma can impede client success in treatment, and ACE-specific programming is useful within their respective treatment programs. Results showed that when manualized treatments are used, they must be adapted to meet the specific needs of Indigenous communities, and culture-as-treatment is a popular approach among Indigenous-led treatment centers, particularly for addressing trauma symptoms.

Associations between trauma and substance use among healthcare workers and public safety personnel during the SARS-CoV-2 (COVID-19) pandemic: the mediating roles of dissociation and emotion dysregulation. Eur J Psychotraumatol 2023; 14:2180706.

Abstract
BACKGROUND Given the highly stressful environment surrounding the SARS-CoV-2 pandemic, healthcare workers (HCW) and public safety personnel (PSP) are at an elevated risk for adverse psychological outcomes, including posttraumatic stress disorder (PTSD) and alcohol/substance use problems. As such, the study aimed to identify associations between PTSD severity, related dissociation and emotion dysregulation symptoms, and alcohol/substance use problems among HCWs and PSP. METHODS A subset of data (N = 498; HCWs = 299; PSP = 199) was extracted from a larger study examining psychological variables among Canadian HCWs and PSP during the pandemic. Structural equation modelling assessed associations between PTSD symptoms and alcohol/substance use-related problems with dissociation and emotion dysregulation as mediators. RESULTS Among HCWs, dissociation fully mediated the relation between PTSD and alcohol-related problems (indirect effect β = .133, p = .03) and emotion dysregulation partially mediated the relation between PTSD and substance-related problems (indirect effect β = .151, p = .046). In PSP, emotion dysregulation fully mediated the relation between PTSD and alcohol-related problems (indirect effects β = .184, p = .005). For substance-related problems among PSP, neither emotion dysregulation nor dissociation (ps >.05) had any effects. CONCLUSION To our knowledge, this is the first study examining associations between PTSD severity and alcohol/substance use-related problems via mediating impacts of emotion dysregulation and dissociation among HCWs and PSP during the SARS-CoV-2 pandemic. These findings highlight dissociation and emotion dysregulation as important therapeutic targets for structured interventions aimed at reducing the burden of PTSD and/or SUD among Canadian HCWs or PSP suffering from the adverse mental health impacts of the SARS-CoV-2 pandemic.

Patel H, O'Connor C, Andrews K, Amlung M, Lanius R, McKinnon MC. Dissociative symptomatology mediates the relation between posttraumatic stress disorder severity and alcohol-related problems. Alcohol Clin Exp Res 2022; 46:289-299. [PMID: 35179786 PMCID: PMC9307004 DOI: 10.1111/acer.14764] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 11/25/2021] [Accepted: 12/12/2021] [Indexed: 01/04/2023]
Abstract
Background Up to 50% of individuals with posttraumatic stress disorder (PTSD) endorse problematic alcohol use. Typically, these individuals present with more complex and often more severe PTSD symptoms than those who do not report problematic alcohol use. Emerging literature suggests that heightened symptoms of dissociation are likewise associated with greater PTSD symptom severity. Despite this knowledge, the role of dissociation in the relation between PTSD severity and alcohol‐related problems has yet to be examined. Here, we explore the mediating role of dissociative symptomatology on the association between PTSD severity and alcohol‐related problems within a PTSD treatment‐seeking sample. Methods Structural equation modeling was used to test the mediating role of dissociative symptomatology between PTSD severity and alcohol‐related problems. Participants [N = 334; mean age (SD) = 44.29 (9.77), 50% female] were drawn from a clinical intake battery database for PTSD in‐patient treatment services at Homewood Health Care, Guelph, ON, Canada. A subset of battery measures assessing PTSD severity, dissociative symptomatology, and alcohol‐related problems were submitted to analysis. Results A significant positive association emerged between PTSD severity and alcohol‐related problems (β = 0.127, p < 0.05) in the absence of dissociative symptomatology. Critically, however, when added to this model, dissociative symptomatology (six unique facets of dissociation assessed by the Multiscale Dissociation Inventory) mediated the relation between PTSD severity and alcohol‐related problems. Specifically, greater PTSD severity was associated with greater dissociative symptomatology (β = 0.566, p < 0.0001), which was in turn associated with greater alcohol‐related problems (β = 0.184, p < 0.05). Conclusions These results suggest that dissociative symptomatology plays a key role in explaining the relation between PTSD severity and alcohol‐related problems. Future studies should examine the impact of targeting dissociative symptomatology specifically in treating individuals with PTSD who endorse alcohol‐related problems.
