Prehabilitation in alcohol dependence as a treatment model for sustainable outcomes. A narrative review of literature on the risks associated with detoxification, from animal models to human translational research

In this review paper we discuss how the overarching concept of pre-habilitation is applicable to alcohol dependence. Central to pre-habilitation are the concepts of expected harm, risks and proactive planning to eliminate the harm or cope with the risks. We review the evidence from animal models, psychological experimental studies, as well as pharmacological studies, on the potential risks and harms associated with medically assisted alcohol detoxification and the current treatment paradigm for alcohol dependence. Animal models provide an approximation mostly of the physical aspect of alcohol withdrawal and detoxification process and make predictions about the development of the phenomena in humans. Despite their limitations, these models provide good evidence that withdrawal from chronic ethanol use induces cognitive impairment, which is worsened by repeated bouts of withdrawal and that these impairments are dependent on the duration of alcohol withdrawal. Initial clinical observations with alcohol dependent patients confirmed increased incidence of seizures. In recent years, accumulating evidence suggest that patients who have had repeated episodes of withdrawal also show changes in their affect, increased craving as well as significant deterioration of cognitive abilities, when compared to patients with fewer withdrawals. Alcohol dependence is associated with tolerance and withdrawal, with neuroadaptations in GABA-A and glutamatergic N-methyl-D-aspartate (NMDA) receptors playing key roles. It is suggested that dysregulation of the NMDA receptor system underpins alcohol related memory impairments. Finally we discuss the Structured Preparation for Alcohol Detoxification (SPADe) as an example of how pre-habilitation has been applied in clinical practice. We discuss the importance of partial control over drinking as an interim step towards abstinence and early introduction of lifestyle changes for both the patient and the immediate environment prior detoxification and while the patient is still drinking

Drugs: education, prevention and policy

Abstract Background: Observations suggest that patterns of drug use may be changing among sex workers and that service provision may be failing this group. The aim of this study was to investigate life, substance-related, and service-provision experiences of women who are both substance users and involved in sex work. Methods: The study was carried out using unstructured recorded confidential interviews and analysis of the themes arising from them. Results: Twelve women were interviewed. Most of them came from an abusive background. There is a vicious circle between sex working and taking drugs-sex work generates funds and drugs facilitate continuation of work. The emergence of crack cocaine was consistently significant. Conclusion: Experiences of the women discussed here are not new and confirm existing knowledge. Important issues related to service provision were discussed. Flexible services are necessary to attract, engage and support this vulnerable group

Psychotic-like experiences with cannabis use predict cannabis cessation and desire to quit- A cannabis discontinuation hypothesis

Background Evidence suggests that cannabis-induced psychotic-like experiences may be a marker of psychosis proneness. The effect of such experiences on cannabis use has not systematically been examined.Methods We undertook a mixed-methods online survey of 1231 cannabis users (including 926 continued users) using the Cannabis Experiences Questionnaire. We examined the effect of psychotic-like and pleasurable experiences on cessation of cannabis and intention to quit. Socio-demographic variables, cannabis use parameters and substance misuse history were included as covariates. Free-text data explored subjective reasons for changes in use.Results Cessation of cannabis use was associated with greater psychotic-like experiences [p < 0.001, Exp(B) 1.262, 95% confidence interval (CI) 1.179-1.351], whilst continued cannabis users were more likely to report pleasurable experiences [p < 0.001, Exp(B) 0.717, 95% CI 0.662-0.776]. Intention to quit cannabis in continued users was associated with greater psychotic-like experiences [p < 0.003, Exp(B) 1.131, 95% CI 1.044-1.225], whilst intention to not quit was significantly associated with increased pleasurable experiences [p < 0.015, Exp(B) 0.892, 95% CI 0.814-0.978]. Whereas former users clearly ascribed cessation to negative experiences, continued users who expressed intention to quit less readily ascribed the intention to negative experiences.Conclusions Elucidation of psychotic-like experiences may form the basis of a therapeutic intervention for those who wish to quit. Cessation in those with cannabis-induced psychotomimetic experiences may offset the risk for the development of a psychotic disorder, in this higher risk group

Alcohol use disorders in people with intellectual disability

This article initially highlights that although the prevalence of alcohol use disorders in people with intellectual disability (PWID) appears to be low, it is a significant issue. This group can be more vulnerable to the adverse effects of alcohol and it is likely that many PWID who have alcohol use disorders are not being identified. We go on to review the limited existing literature on treatment for PWID who have alcohol use disorders and the challenges in meeting the needs of this patient group. We explore how assessment and treatment of alcohol use disorders in this population can be and needs to be tailored to the needs of PWID on an individual basis. There is also discussion about the use of incapacity legislation to treat this group. LEARNING OBJECTIVES Be aware that alcohol use disorders can be especially problematic for PWID, that such disorders can often go undetected and that adapted screening techniques may be needed to identify such problems Understand the difficulties that this population has in accessing addiction services and that successful management of PWID who misuse alcohol is usually dependent on appropriate joint working between intellectual disability and addiction services Be aware that PWID are not a homogeneous group, rather they vary widely in their abilities, necessitating interventions tailored to the individual, and that the use of compulsory measures to manage PWID who lack capacity regarding to their alcohol use should be done with cautionPostprintPeer reviewe

An exploration of identity change in post-detoxification alcohol dependent individuals

Purpose: Dependent alcohol use is a severe addictive disorder with significant enduring consequences for health and social functioning. We aimed to inductively explore the process of identity change for alcohol dependent people progressing through a ‘pre-habilitation’ intervention, alcohol detoxification and post-detoxification recovery support. Design: Qualitative study as a part of a process evaluation situated within a UK feasibility trial of a group-based intervention in preparation for structured alcohol detoxification. Semi-structured qualitative interviews (face-to-face or telephone) collected self-reported data on experiences of treatment provision as part of the feasibility trial. Thematic analysis of transcripts and iterative categorisation of identity related themes and concepts was conducted with verification of analysis undertaken by a second coder. Findings: Identity change was revealed in participant narratives around the meta themes of external (social-identity) and internal (self-identity) concepts. External influences impacting social identity were key, having influenced initiation into alcohol use, influencing acceptance of the stigmatised ‘alcoholic’ label, and then being central to the treatment journey. Internal influences on self-identity also impacted on the process of identity change. In recovery, there was hope in discovering a new ‘normal’ identity or rediscovering normality. Originality: Analysis demonstrates that moving from regular alcohol use to problematic use is a journey of identity change that is influenced at the macro (cultural), meso (group) and micro (relational) social levels. Throughout the treatment journey, social influences in gaining a new non-drinker identity are key. Findings suggest a need for long term support through treatment and community-based groups specifically to foster positive identity change that may not have been addressed previously

A feasibility trial of an intervention in alcohol dependence for structured preparation before detoxification versus usual care: the SPADe trial results

Background Individuals who are ‘moderately’ or ‘severely’ dependent consume alcohol at levels that are likely to have a severe impact on their own health and mortality, the health and behaviours of others (family members) and to have economic and social implications. Treatment guidelines suggest that treatment needs to be planned with medically assisted withdrawal (also referred to as detoxification), and aftercare support but outcomes are poor with low proportions engaging in after care and high relapse rates. An approach of structured preparation before alcohol detoxification (SPADe) puts an emphasis on introducing lifestyle changes, development of coping strategies for cravings, stress and emotions as well as introducing changes to the immediate family and social environment in advance of alcohol cessation. Such a pre-habilitation paradigm compliments the established treatment approach. The key research question was: can we design a large scale, randomised controlled trial (RCT) that will answer whether such an approach is more effective than usual care in helping individuals to maintain longer periods of alcohol abstinence? Methods This is a pragmatic, parallel, two-arm, feasibility RCT comparing SPADe and usual care against usual care only in maintaining alcohol abstinence in adults with alcohol dependence receiving care in two community addiction services in London. Feasibility outcomes, exploration of primary and secondary clinical outcomes and health economic outcomes are analysed. The trial follows the guidelines of phase 2 of the Medical Research Council (MRC) for complex interventions. Results We were able to recruit 48/50 participants during a period of 9 months. Retention in the trial for the whole period of the 12 months was 75%. Treatment compliance was overall 44%. Data completion for the primary outcome was 65%, 50% and 63% at 3, 6 and 12 months, respectively. The intervention group had more days abstinent in the previous 90 days at the 12 months (n = 54.5) versus control (n = 41.5). Conclusions The results of this feasibility trial indicate that with the appropriate modifications, a full multicentred trial would be possible to test the effectiveness and cost-effectiveness of a pre-habilitation approach such as the SPADe group intervention in addition to usual care against usual care only.

A global survey on changes in the supply, price, and use of illicit drugs and alcohol, and related complications during the 2020 COVID-19 pandemic

Background and Aims : COVID-19 has infected more than 77 million people worldwide and impacted the lives of many more, with a particularly devastating impact on vulnerable populations, including people with substance use disorders (SUDs). Quarantines, travel bans, regulatory changes, social distancing, and "lockdown" measures have affected drug and alcohol supply chains and subsequently their availability, price, and use patterns, with possible downstream effects on presentations of SUDs and demand for treatment. Given the lack of multicentric epidemiologic studies, we conducted a rapid global survey within the International Society of Addiction Medicine (ISAM) network in order to understand the status of substance-use patterns during the current pandemic. Design : Cross-sectional survey. Setting : Worldwide. Participants : Starting on April 4, 2020 during a 5-week period, the survey received 185 responses from 77 countries. Measurements : To assess addiction medicine professionals' perceived changes in drug and alcohol supply, price, use pattern, and related complications during the COVID-19 pandemic. Findings : Participants reported (among who answered "decreased" or "increased") a decrease in drug supply (69.0%) and at the same time an increase in price (95.3%) globally. With respect to changes in use patterns, an increase in alcohol (71.7%), cannabis (63.0%), prescription opioids (70.9%), and sedative/hypnotics (84.6%) use was reported, while the use of amphetamines (59.7%), cocaine (67.5%), and opiates (58.2%) was reported to decrease overall. Conclusions : The global report on changes in the availability, use patterns, and complications of alcohol and drugs during the COVID-19 pandemic should be considered in making new policies and in developing mitigating measures and guidelines during the current pandemic (and probable future ones) in order to minimize risks to people with SUD.Publisher PDFPeer reviewe

COVID-19 and Substance Use Disorders:Recommendations to a Comprehensive Healthcare Response. An International Society of Addiction Medicine (ISAM) Practice and Policy Interest Group Position Paper

Coronavirus disease 2019 (COVID-19) is escalating all over the world and has higher morbidities and mortalities in certain vulnerable populations. People Who Use Drugs (PWUD) are a marginalized and stigmatized group with weaker immunity responses, vulnerability to stress, poor health conditions, high-risk behaviors, and lower access to health care services. These conditions put them at a higher risk of COVID-19 infection and its complications. In this paper, an international group of experts on addiction medicine, infectious diseases, and disaster psychiatry explore the possible raised concerns in this issue and provide recommendations to manage the comorbidity of COVID-19 and Substance Use Disorder (SUD).Publisher PDFPeer reviewe

World Addiction Medicine Reports : formation of the International Society of Addiction Medicine (ISAM) Global Expert Network (ISAM-GEN) and Its global surveys

Funding: All the infrastructure funding of this initiative is supported by the International Society of Addiction Medicine (ISAM). We will be open to fundraising for specific projects within the platform and future collaboration with external partners.Addiction medicine is a dynamic field that encompasses clinical practice and research in the context of societal, economic, and cultural factors at the local, national, regional, and global levels. This field has evolved profoundly during the past decades in terms of scopes and activities with the contribution of addiction medicine scientists and professionals globally. The dynamic nature of drug addiction at the global level has resulted in a crucial need for developing an international collaborative network of addiction societies, treatment programs and experts to monitor emerging national, regional, and global concerns. This protocol paper presents methodological details of running longitudinal surveys at national, regional, and global levels through the Global Expert Network of the International Society of Addiction Medicine (ISAM-GEN). The initial formation of the network with a recruitment phase and a round of snowball sampling provided 354 experts from 78 countries across the globe. In addition, 43 national/regional addiction societies/associations are also included in the database. The surveys will be developed by global experts in addiction medicine on treatment services, service coverage, co-occurring disorders, treatment standards and barriers, emerging addictions and/or dynamic changes in treatment needs worldwide. Survey participants in categories of (1) addiction societies/associations, (2) addiction treatment programs, (3) addiction experts/clinicians and (4) related stakeholders will respond to these global longitudinal surveys. The results will be analyzed and cross-examined with available data and peer-reviewed for publication.Peer reviewe
