Continuing care for patients with alcohol use disorders: A systematic review

BACKGROUND A chronic care perspective should be adopted in the treatment of patients with alcohol use disorders (AUDs). Initial treatment in a more intense psychiatric care setting should be followed by continuing care. This systematic review aims to identify effective continuing care interventions for patients with AUDs. METHODS Electronic databases were searched up to February 2013 (MEDLINE, EMBASE, CENTRAL, CINAHL and PsycINFO) to identify RCTs studying continuing care interventions for patients with AUDs. Study selection and quality appraisal was done independently by two reviewers. Drinking and treatment engagement outcomes were considered. Relative risks and mean differences were calculated with 95% confidence intervals. A statistical pooling of results was planned. RESULTS 20 trials out of 15,235 identified studies met the inclusion criteria. Only six were evaluated as methodologically strong enough and included for further analysis. Interventions ranged from telephone calls and nurse follow-up to various forms of individual or couples counseling. Four trials suggested that supplementing usual continuing care with an active intervention empowering the patient, could be beneficial to drinking outcomes. Effect sizes were limited and not consistent across all outcomes. Because of heterogeneity in the interventions and outcome measures, a meta-analysis could not be performed. CONCLUSION For the treatment of a disease with such devastating consequences, it is remarkable how few high quality studies are available. Adding an active intervention to usual continuing care seems to improve treatment outcomes. We propose an integrated care program with different elements from the selected studies and discuss implications for further research.

The Impact of Accelerated Right Prefrontal High-Frequency Repetitive Transcranial Magnetic Stimulation (rTMS) on Cue-Reactivity: An fMRI Study on Craving in Recently Detoxified Alcohol-Dependent Patients

In alcohol-dependent patients craving is a difficult-to-treat phenomenon. It has been suggested that high-frequency (HF) repetitive transcranial magnetic stimulation (rTMS) may have beneficial effects. However, exactly how this application exerts its effect on the underlying craving neurocircuit is currently unclear. In an effort to induce alcohol craving and to maximize detection of HF-rTMS effects to cue-induced alcohol craving, patients were exposed to a block and event-related alcohol cue-reactivity paradigm while being scanned with fMRI. Hence, we assessed the effect of right dorsolateral prefrontal cortex (DLPFC) stimulation on cue-induced and general alcohol craving, and the related craving neurocircuit. Twenty-six recently detoxified alcohol-dependent patients were included. First, we evaluated the impact of one sham-controlled stimulation session. Second, we examined the effect of accelerated right DLPFC HF-rTMS treatment: here patients received 15 sessions in an open label accelerated design, spread over 4 consecutive days. General craving significantly decreased after 15 active HF-rTMS sessions. However, cue-induced alcohol craving was not altered. Our brain imaging results did not show that the cue-exposure affected the underlying craving neurocircuit after both one and fifteen active HF-rTMS sessions. Yet, brain activation changes after one and 15 HF-rTMS sessions, respectively, were observed in regions associated with the extended reward system and the default mode network, but only during the presentation of the event-related paradigm. Our findings indicate that accelerated HF-rTMS applied to the right DLPFC does not manifestly affect the craving neurocircuit during an alcohol-related cue-exposure, but instead it may influence the attentional network.

Influence of Body Mass Index on Hair Ethyl Glucuronide Concentrations

Aim Analysis of ethyl glucuronide (EtG) concentrations in hair is increasingly used to estimate the consumption of alcohol of the prior months. Linear correlations between the amount of alcohol consumed and the concentration of EtG in hair have been reported, and several variables that may influence this correlation have been investigated: e.g. cosmetic hair treatments, gender influences or hair color. Here, we investigate the influence of body mass index (BMI) on this correlation. Methods A post hoc analysis on the influence of BMI on the relation between amounts of alcohol consumed and the measured EtG concentrations in hair in 199 participants. Results Our data show higher EtG concentrations in participants with high BMI (≥25) compared to participants with low BMI (<25) (P = 0.001) across a wide range of amounts of alcohol consumed. Conclusions We conclude that BMI should be taken into account when interpreting hair EtG concentrations. Short summary Ethyl glucuronide concentrations in hair (hEtG) can be used to estimate the consumption of alcohol of the prior months. Body mass index (BMI) influences this relation and BMI should be taken into account when interpreting hEtG concentrations in participants with high BMI (≥25) compared to participants with low BMI (<25).

Causal attribution in individuals with subclinical and clinical autism spectrum disorder: An fMRI study

This neuroimaging study compares brain activation during causal attribution to three different attribution loci (i.e., self, another person, and situation) across a typical population without (N = 20) or with subclinical autism spectrum symptoms (N = 18) and a clinical population with autism spectrum disorder (ASD; N = 11). While they underwent fMRI, all participants read short sentences describing positive and negative behaviors and thoughts of another person directed toward the participant (i.e., “you”). Participants were then asked to attribute these behaviors to themselves, the other person, or the situation. Behavioral measures revealed self-serving attributions (i.e., attributing positive events to the self, while attributing negative events externally from the self) in all three participant groups. Neural measures revealed a great deal of shared activation across the three attribution loci and across the three participant groups in the temporo-parietal junction, the posterior superior sulcus, and the precuneus. Comparison between groups revealed more widespread activation in both subclinical and clinical ASD participants, which may be indicative of the extraneural resources these participants invest to compensate their impairments.

The Construction of the First Validated (Evidence Based) Guideline for Dual Diagnosis of ADHD and SUD; Data from Focus Groups

This study aims to obtain more information about the expectations and experiences of patients with attention deficit hyperactivity disorder (ADHD) and substance use disorder (SUD) and about the opinions of addiction care professionals. This information has been used to develop the first multidisciplinary guideline for identification and treatment of ADHD in addicted patients. Focus group interviews were performed with two groups of professionals and a group of patients of one of them. The interviews were transcribed and analyzed using QSR NVivo 9 software. The analysis revealed a great difference between addicted inpatients and outpatients as to the possibilities of diagnosing and treating ADHD. It is difficult to make a proper diagnosis in patients who are not fully abstinent, as there are no validated diagnostic instruments for this target group. Observation is seen as more important than questionnaires but there have been no studies on the utility of observation. Patients often ask for non-pharmacological treatment. Underdiagnosing of ADHD in addicted patients is a persistent problem. Additional research is required into diagnostic tools for making a proper diagnosis in patients not fully abstinent as well as into pharmacological interactions. Observation, degree of distress and cognitive examination should form part of the diagnostic process. The positive experiences in the residential addiction services with non-pharmacological well-grounded, structured treatment methods for addiction offer a perspective to develop specific methodologies adapted to patients with comorbid ADHD.

Barriers to Implementation of Treatment Guidelines for ADHD in Adults With Substance Use Disorder

Objective: Attention deficit hyperactivity disorder (ADHD) is common among adult patients with a substance use disorder, yet often goes undetected. This is a qualitative study to explore implementation barriers to a guideline developed in Belgium for the recognition and treatment of ADHD in adult patients with substance use disorder and to gain a better understanding of the strategies to overcome these barriers. Methods: Focus groups were conducted with caregivers and patients to explore experiences with comorbid substance use disorder and ADHD. The barriers reported in these focus groups became the subject of further study in focus groups with addiction professionals (physicians, psychiatrists, and psychologists) who had tried the guideline and with psychiatrists specializing in addiction but without experience with ADHD. Results: Our analysis revealed a number of barriers to the implementation of this guideline, including lack of information from the family, pressure from patients and caregivers to make an ADHD diagnosis, and the potential for abuse of ADHD medication. Furthermore, diagnostic instruments for ADHD have not been validated in people with substance use disorder. Although patients with ADHD are usually treated in an outpatient setting, patients with ADHD comorbid with substance use disorder are difficult to identify in an outpatient setting for various reasons. Finally, there is a lack of specific ADHD expertise in substance use treatment organizations. Conclusions: Despite the availability of an approved guideline for recognizing and treating adult ADHD in patients with a substance use disorder, underdiagnosis and inadequate treatment still persist. As in general substance use treatment, medication only plays a supportive role in the treatment of substance use disorder with comorbid ADHD. An integrated approach and further improvements in the competence of practitioners may help to reduce the resistance to diagnosing ADHD in substance use treatment centers. Practitioners who specialize in addiction medicine and therapists without medical education view the problem from different perspectives and therefore each group needs specific information and training. Targeted interventions need to be developed to keep these patients in treatment.

Guideline for Screening, Diagnosis and Treatment of ADHD in Adults with Substance Use Disorders

Currently there is no guideline for the screening, diagnosis and treatment of adult attention deficit/hyperactivity disorder (ADHD) in patients with a substance use disorder (SUD). The aim was to develop such a guideline, starting out from a systematic review and based on the methodology of the Scottish Intercollegiate Guideline Network (SIGN). Due to the lack of scientific evidence on some of the topics, the guideline is a combination of evidence based and practice based recommendations. Given the high prevalence of ADHD in treatment seeking SUD patients and the availability of valid screening instruments, all treatment seeking SUD patients should be screened for ADHD. Diagnosis of ADHD should be based on clinical observation and history taking, including informant data. Integrated treatment of ADHD and SUD is recommended, including pharmacotherapy, psycho-education, coaching, and cognitive behavioral therapy (CBT). The lack of scientific data and the overall lack of expertise in the field are significant obstacles to the implementation of the guideline. Intensive training programs in the substance abuse sector need to be organized to implement these guidelines.

International Consensus Statement on Screening, Diagnosis and Treatment of Substance Use Disorder Patients with Comorbid Attention Deficit/Hyperactivity Disorder

Adult attention deficit/hyperactivity disorder (ADHD) often co-occurs with substance use disorders (SUD) and is associated with early onset and more severe development of SUD and with reduced treatment effectiveness. Screening tools allow for a good recognition of possible ADHD in adults with SUD and should be used routinely, followed by an ADHD diagnostic process initiated as soon as possible. Simultaneous and integrated treatment of ADHD and SUD, using a combination of pharmaco- and psychotherapy, is recommended. Long-acting methylphenidate, extended-release amphetamines, and atomoxetine with up-titration to higher dosages may be considered in patients unresponsive to standard doses. This paper includes evidence- and consensus-based recommendations developed to provide guidance in the screening, diagnosis and treatment of patients with ADHD-SUD comorbidity.

Development and Validation of Quality Indicators on Continuing Care for Patients With AUD: A Delphi Study

AIMS To develop indicators to assess quality of continuing care for persons with alcohol use disorder (AUD). METHODS A guideline-based RAND-modified Delphi method was used to develop and validate indicators regarding the process and outcome of continuing care. We systematically searched for evidence-based guidelines and existing quality indicators. A multidisciplinary expert panel prioritized recommendations using a written questionnaire followed by a group discussion. Important recommendations were then translated to quality indicators. The panel subsequently selected indicators that were measurable and applicable in Belgium. In a final round the indicators face-validity was assessed. RESULTS We extracted 69 recommendations from 06 guidelines and 17 relevant quality indicators. Of all, 13 indicators remained after 03 written rounds and 02 group discussions. CONCLUSIONS This study describes a systematic approach to develop and validate quality indicators for continuing care for AUD. The final set of selected indicators consisted of 10 process and 03 outcome indicators. As the level of evidence of effective continuing care components is very low further development of the indicators is recommended. SHORT SUMMARY This study describes a systematic approach to develop and validate quality indicators for continuing care for AUD. The proposed set of indicators consisted of 10 process and 03 outcome indicators. As the level of evidence of effective continuing care components is very low further development of the indicators is recommended.

Focus Groups: a Method of Dialogue Between Clinicians and Research

Focus groupsare a qualitative research tool, firstly designed to explore effects of filmsand television programs to viewers as well as the effect of preventive healthmessages. The method is widely used to investigate patient experiences inrelation to their disease and theircontacts with health. The method has also been found to be helpful forthe exploration of the attitudes of care providers and their resistance to some. It helps to understand the patient and the caregiver and to explore newresearch areas which can then be further investigated by quantitative methods. There are three main reasons why this method isadvantageous in the development of a guideline. 1/ in order to keep the guideline in line with the needsand the constraints of the clinicians and the patients. 2/ to increase the implementation of the guideline. 3/ to gather expert opinions and best practices. Thisis especially important when a topic is largely unexplored. Until recently there was no guideline for thescreening, diagnosis and treatment of attention deficit / hyperactivitydisorder (ADHD) in patients with a substance use disorder (SUD). The aim was todevelop such a guideline, starting out from a systematic review and based onthe methodology of the Scottish Intercollegiate Guideline Network (SIGN). Dueto the lack of scientific evidence on some of the topics, the guideline is acombination of evidence based and practice based recommendations.
