Virtual reality-assisted cognitive behavioral therapy for patients with alcohol use disorder: a randomized feasibility study.

Introduction: Cognitive behavioral therapy (CBT) is an evidence-based treatment for alcohol use disorder (AUD). Exposure to high-risk situations in virtual reality (VR) has been suggested to have a potential therapeutical benefit, but no previous study has combined VR and CBT for AUD. We aimed to investigate the feasibility of using VR-simulated high-risk environments in CBT-based treatment of AUD. Methods: We randomized ten treatment-seeking AUD-diagnosed individuals to three sessions of conventional CBT or VR-assisted CBT performed at two outpatient clinics in Denmark. In each session, patients randomized to VR-CBT were exposed to VR-simulations from a restaurant to induce authentic thoughts, emotions, physiological reactions, and craving for CBT purposes. The primary outcome measure was feasibility: Drop-out rate, psychological reactions, and simulator sickness. Secondary outcomes were assessment of preliminary short-term changes in alcohol consumption and craving from baseline to one-week and one-month follow-up. In addition, the study was conducted for training in operationalization of VR equipment, treatment manuals, and research questionnaires. Results: The majority of patients completed all study visits (90%). VR induced authentic high-risk related thoughts, emotions, and physiological reactions that were considered relevant for CBT by patients and therapists. Four of five patients randomized to VR-CBT experienced cravings during VR simulations, and most of these patients (3/5) experienced mild simulator sickness during VR exposure. The preliminary data showed that patients receiving VR-CBT had more reduction in alcohol consumption than patients receiving conventional CBT at one week- (median 94% vs. 72%) and one-month follow-up (median 98% vs. 55%). Similar results were found regarding changes in cravings. Conclusion: We demonstrated VR-CBT to be a feasible intervention for patients with AUD which supports continued investigations in a larger randomized clinical trial evaluating the efficacy of VR-CBT.

Perceived advantages and disadvantages of substance use in a dual diagnosis population with severe mental disorders and severe substance use disorder. Considering the self-medication hypothesis.

AIM: Based on a large cohort of dual diagnosis patients, the aim of this study was to quantify the patient-perceived problems and advantages of their substance use and relate the quantity of problems to the substance type and psychiatric diagnosis. MATERIAL: Data comes from a naturalistic cohort admitted to an in-patient facility in Denmark specialized in integrated dual diagnosis treatment. We included 1076 patients at their first admission to the facility from 2010 to 2017. Participants completed 607 DrugCheck and 130 DUDIT-E questionnaires. METHOD: we analyzed the questionnaires and included admission diagnosis by use of t-test and ANOVA to depict the patterns in substance use in relation to psychiatric diagnosis. RESULTS: The three most common substance related problems according to the DrugCheck questionnaire were: feeling depressed, financial problems, and losing interest in daily activities. From DUDIT-E, the highest-ranking negative substance related effects were financial ruin, deterioration of health, and problems at work. Effects on social life relationships were also evident with more than 40% of participants. The top three positive substance related effects reported were relaxation, improved sleep, and control over negative emotions. The number of problems listed varied significantly with the type of preferred substance. Patients using pain medication, sedatives, central stimulants, and alcohol reported most problems. Diagnosis did not differentiate the problems experienced. Results partially support the broad self-medication hypothesis for patients with severe mental illness, but also points out that patients are well aware of negative effects.

Polypharmacy in antipsychotic pharmacological treatment among patients with dual diagnosis in Denmark.

INTRODUCTION: Antipsychotic polypharmacy is prevalent, however literature on antipsychotic polypharmacy during treatment among patients with dual diagnosis is largely non-existent. This study aims to investigating the extent of antipsychotic polypharmacy dual diagnosis patients during hospitalisations. METHODS: Utilizing cohort data from an integrated dual diagnosis in-patient facility from patients hospitalized between 1 March 2012, to 31 December 2016, we compared the mean antipsychotic medication administered at admission and discharge and examined covariate associations with logistic regressions. RESULTS: The study identified 907 hospital admissions, of which 641 were the first for each patient during the period. At admission, 74.1% received antipsychotics; polypharmacy spanned psychiatric disorders. categories. Patients with affective or personality spectrum disorders were less likely to have antipsychotic polypharmacy upon admission compared to those with psychosis spectrum disorders. 2013-2016 admissions presented less polypharmacy than 2012. Mean antipsychotic numbers remained unchanged for >30-day hospitalizations. Patients admitted without antipsychotic polypharmacy with an affective spectrum disorder or aged 41-50 or over 51 years old were less likely to be discharged with antipsychotic polypharmacy when compared to patients with psychosis spectrum disorder or aged 18-30 years old. CONCLUSION: Approximately three-quarters of admitted patients were treated with antipsychotic medication. Antipsychotic polypharmacy was observed across all psychiatric disorder categories, indicating potential off-label use. Addressing antipsychotic polypharmacy during treatment is challenging, even for specialised facilities. Rational antipsychotic prescribing, deprescribing protocols, and further prescription pattern research are needed.

Virtual reality-assisted cognitive behavioural therapy for outpatients with alcohol use disorder (CRAVR): a protocol for a randomised controlled trial.

INTRODUCTION: Alcohol use disorder (AUD) is a brain disorder linked to over 200 health conditions. Cognitive behavioural therapy (CBT) is considered the best practice in the treatment of AUD, but more than 60% of patients relapse within the first year after treatment. Psychotherapy combined with virtual reality (VR) has received increasing interest in the treatment of AUD. However, existing studies have primarily investigated the use of VR for cue reactivity. We therefore aimed to investigate the effect of VR-assisted CBT (VR-CBT). METHODS AND ANALYSIS: This study is an assessor-blinded, randomised clinical trial being conducted at three outpatient clinics in Denmark. We will randomise 102 patients to 14 individual sessions of either manualised VR-CBT or CBT. The VR-CBT group will receive exposure to immersive high-risk VR situations from a pub, bar/party, restaurant, supermarket and at-home (30 videos) to activate high-risk-related beliefs and cravings for subsequent modification using CBT techniques. The treatment period is 6 months, and follow-up visits will be performed 3, 6, 9 and 12 months after inclusion. The primary outcome measure is the change in total alcohol consumption from baseline to 6 months after inclusion, measured with the Timeline Followback Method. Key secondary outcome measures include changes in the number of heavy drinking days, alcohol cravings, cognition, and symptoms of depression and anxiety. ETHICS AND DISSEMINATION: Approval has been obtained by the research ethics committee in the Capital Region of Denmark (H-20082136) and the Danish Data Protection Agency (P-2021-217). All patients will receive both oral and written information about the trial and written informed consent will be obtained from each patient before inclusion. The study results will be disseminated in peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: ClinicalTrial.gov, NCT05042180.

Stability of admission diagnoses; data from a specialized in-patient treatment facility for dual diagnosis.

AIM: We investigated the stability of diagnoses during admission over an 11-year period in patients admitted to a highly specialized integrated dual diagnosis treatment facility in Denmark using diagnosis coded in patient charts. MATERIALS AND METHODS: Admission and discharge diagnoses from patient files were examined for stability of primary diagnosis and association with year of admission, age, sex, and duration of admission, in 1570 patients from 2007 to 2017. RESULTS: A vast proportion (69.6%) of the patients retained their diagnosis during a 3-month admission. Stability was highest for schizophrenia spectrum diagnoses and lowest for unspecified diagnosis. Type of primary diagnosis, age, and length of admission was associated with lower likelihood of a stable primary diagnosis. CONCLUSIONS: Long-term admission for psychiatric patients with substance use disorder (SUD) was significantly associated with stability of diagnosis. The finding calls for longer observation of dual diagnosis patients to ensure that relevant diagnosis is given, and consequently that the appropriate clinical treatment such as psychopharmacological as well as non-pharmacological intervention can be applied.
