RESUMEN

INTRODUCTION: Amphetamine-type stimulants (ATSs) are the second most commonly used class of illegal substances in Europe. Although concurrent substance use has been subject to research, little is known about associations between concurrent use of cocaine, alcohol, or cannabis and ATS dependence. We expect that the concurrent use of any of the substance, especially cannabis and cocaine, is associated with ATS dependence. METHODS: Cross-sectional data were gathered within the European ATTUNE study in 2018/2019. Participants (N = 721) were asked about their consumption patterns and social, psychological, and economic situation. Multivariate logistic regressions were carried out for associations between ATS dependence and use combinations of frequent cocaine, alcohol, or cannabis, with the reference group of no frequent concurrent use (model 1). Model 2 calculated associations for ATS dependence with lifetime methamphetamine use for respective use combinations. RESULTS: The study population was on average 28.9 years old (SD = 7.7), with the majority being male (63.5%). In model 1, the adjusted odds ratio (aOR) for frequent alcohol use was 0.70 (confidence interval [CI] 0.41-1.20). Similar results were shown for model 2 (aOR 0.82, CI 0.42-1.62). Frequent cannabis use significantly reduced the chance for ATS dependence by 50% in adjusted model 1 (aOR 0.50, CI 0.28-0.89) and by 62% in model 2 (aOR 0.38, CI 0.18-0.82). For frequent cocaine use, models 1 and 2 report an aOR at 1.37 (CI 0.58-3.25) and 2.39 (CI 0.77-7.43), although not statistically significant. Frequent users of all 3 substances had a significant 3-fold chance for ATS dependence (model 1: aOR 2.98, CI 1.16-7.63; model 2: aOR 2.95, CI 1.02-8.58). DISCUSSION: Against initial hypotheses, frequent concurrent use of alcohol or cannabis generally decreased chances for ATS dependence. An explanation could be the study population, which consists of many irregular users of ATS, who mainly consume alcohol or cannabis. Cocaine generally increased chances, although results were not significant. The frequent use of all 3 substances together with ATS in the last year was significantly associated with dependence, thus reporting important information for treatment services. Further research is needed for disentangling causal relationships underlying these associations and for pinpointing consequences for relapse prevention and retention success.

RESUMEN

The standardization of cannabis doses is a priority for research, policy-making, clinical and harm-reduction interventions and consumer security. Scientists have called for standard units of dosing for cannabis, similar to those used for alcohol. A Standard Joint Unit (SJU) would facilitate preventive and intervention models in ways similar to the Standard Drink (SD). Learning from the SD experiences allows researchers to tackle emerging barriers to the SJU by applying modern forecasting methods. During a workshop at the Lisbon Addictions Conference 2019, a back-casting foresight method was used to address challenges and achieve consensus in developing an SJU. Thirty-two professionals from 13 countries and 10 disciplines participated. Descriptive analysis of the workshop was carried out by the organizers and shared with the participants in order to suggest amendments. Several characteristics of the SJU were defined: (1) core values: easy-to use, universal, focused on THC, accurate, and accessible; (2) key challenges: sudden changes in patterns of use, heterogeneity of cannabis compounds as well as in administration routes, variations over time in THC concentrations, and of laws that regulate the legal status of recreational and medical cannabis use); and (3) facilitators: previous experience with standardized measurements, funding opportunities, multi-stakeholder support, high prevalence of cannabis users, and widespread changes in legislation. Participants also identified three initial steps for the implementation of a SJU by 2030: (1) Building a task-force to develop a consensus-based SJU; (2) Expanded available national-level data; (3) Linking SJU consumption to the concept of "risky use," based on evidence of harms.

RESUMEN

Background: New approaches are required to slow down or reverse increasing trends of levels of delta-9-tetrahydrocannabinol (THC) and cannabis-attributable hospitalizations in Germany. Legal access to cannabis may constitute one viable effective policy response; however, available evidence does not suffice to inform a regulation model for Germany. The proposed study aims to reduce harm for cannabis users through legal access to herbal cannabis through pharmacies. Protocol: A quasi-experimental study comparing cannabis users with legal access to herbal cannabis (Berlin, intervention group) to those without legal access (Hamburg, control group) (total N=698). As the primary outcome, we hypothesize that: 1) illegal THC consumption will reduce by at least 50% in the intervention group and 2) total THC exposure in the intervention group will be reduced by at least 10% lower than that of the control group, taking into account baseline values. Secondary outcomes comprise measures of frequency of use, THC-impaired driving, and mode of administration. Paired t-tests and multilevel regression models will be performed for statistical analyses. Discussion: This study proposal is currently being reviewed by the 'Federal Institute for Drugs and Medical Devices' - the body responsible for approving research studies on classified substances, including cannabis. Upon approval and prior to the start of the study, a full ethical review will be undertaken. Results may inform a regulation model for Germany and other jurisdictions and are expected to deepen the understanding of the effects of legal access to cannabis.

RESUMEN

BACKGROUND: Amphetamine-type stimulants (ATS) are the second most commonly used illicit drugs in Europe and globally. However, there is limited understanding of what shapes patterns of ATS use over the life course. The ATTUNE project "Understanding Pathways to Stimulant Use: a mixed methods examination of the individual, social and cultural factors shaping illicit stimulant use across Europe" aims to fill this gap. Here we report initial findings from the life course chart exercise conducted as part of qualitative interviews with ATS users and nonusers. METHODS: Two hundred seventy-nine in-depth qualitative interviews were conducted with five ATS user groups (current and former dependent users;current and former frequent users;non-frequent users) and one group of exposed non-ATS users in five European countries (Germany, UK, Poland, Netherlands and Czech Republic). As part of the interviews, we used life course charts to capture key life events and substance use histories. Life events were categorised as either positive, neutral or negative, and associated data were analysed systematically to identify differences between user groups. We applied statistical analysis of variance (ANOVA) and analysis of covariance (ANCOVA) to test for group differences. RESULTS: Out of 3547 life events documented, 1523 life events were categorised as neutral, 1005 life events as positive and 1019 life events as negative. Current and formerly dependent ATS users showed more negative life events for the entire life course after age adjustment. Although some group differences could be attributed to the individuals' life course prior to first ATS use, most negative life events were associated with periods of ATS usage. A detailed analysis of the specific life domains reveals that dominantly, the social environment was affected by negative life events. CONCLUSIONS: For non-dependent, frequent and non-frequent ATS users, negative life events from the period of ATS use do not become obvious in our analysed data. Besides preventing a pathway into ATS dependency, the aim of an intervention should be to reduce the harm by for example drug testing which offers also the opportunity for interventions to prevent developing a substance use dependency. For the group of dependent ATS users, our study suggests holistic, tailored interventions and specialist treatment services are needed, as a single, simple intervention is unlikely to cover all the life domains affected.

RESUMEN

BACKGROUND: Hepatitis C virus (HCV) infection is highly prevalent among people who inject drugs (PWID). Accurate data on HCV prevalence and incidence rates among patients receiving opioid substitution treatment (OST) are needed to estimate the current and future burden of HCV infections in this high-risk population. METHODS: Baseline data from routine care were collected between October 2014 and June 2016 from randomly selected OST facilities in Germany. The primary outcome measure was the HCV status (antibody and RNA prevalence). Patients who were HCV antibody-negative at baseline were followed up after 12 months to calculate the HCV incidence rate. RESULTS: Sixty-three facilities from 14 German Federal States provided clinical data for a total of 2466 OST patients. HCV antibody and HCV RNA prevalence were 58.8% (95% confidence interval [CI], 56.8%-60.8%) and 27.3% (95% CI, 25.5%-29.2%), respectively. At baseline, a total of 528 patients (21.4%) had previously undergone antiviral treatment. Moreover, lower HCV RNA prevalence was associated with female gender, employment, younger age, and shorter duration of OST and opioid dependence. The HCV incidence rate was 2.5 cases per 100 person-years. CONCLUSIONS: The low HCV RNA prevalence and HCV incidence rates confirm that OST in Germany is an effective setting both for treating chronic HCV infections and for preventing new infections among PWID. Scaling up the provision of OST, HCV testing, and HCV treatment among OST patients are important public health strategies for reducing HCV infections in this high-risk population.

RESUMEN

INTRODUCTION: Mental healthcare is one of the biggest challenges for healthcare systems. Comorbidities between different mental disorders are common, and patients suffer from a high burden of disease. While the effectiveness of collaborative and stepped care models has been shown for single disorders, comorbid mental disorders have rarely been addressed in such care models. The aim of the present study is to evaluate the effectiveness of a collaborative and stepped care model for depressive, anxiety, somatoform and alcohol use disorders within a multiprofessional network compared with treatment as usual. METHODS AND ANALYSIS: In a cluster-randomised, prospective, parallel-group superiority trial, n=570 patients will be recruited from primary care practices (n=19 practices per group). The intervention is a newly developed collaborative and stepped care model in which patients will be treated using treatment options of various intensities within an integrated network of outpatient general practitioners, psychiatrists, psychotherapists and inpatient institutions. It will be compared with treatment as usual with regard to effectiveness, cost-effectiveness and feasibility, with the primary outcome being a change in mental health-related quality of life from baseline to 6 months. Patients in both groups will undergo an assessment at baseline, 3, 6 and 12 months after study inclusion. ETHICS AND DISSEMINATION: The study has been approved by the ethics committee of the Hamburg Medical Association (No. PV5595) and will be carried out in accordance with the principles of the Declaration of Helsinki. For dissemination, the results will be published in peer-reviewed journals and presented at conferences. Within the superordinate research project Hamburg Network for Health Services Research, the results will be communicated to relevant stakeholders in mental healthcare. TRIAL REGISTRATION NUMBER: NCT03226743.

RESUMEN

INTRODUCTION: Amphetamine-type stimulants (ATS) including amphetamine, methylenedioxymethamphetamine/'ecstasy', methamphetamine, synthetic cathinones and 'Ritalin' are the second most commonly used illicit drugs globally. Yet, there is little evidence on which factors are associated with the development of different patterns of ATS use over the life course. This study aims to examine which individual, social and environmental factors shape different pathways and trajectories of ATS consumption. The study will be conducted in five European countries: Germany, the Netherlands, Poland, Czech Republic and the UK. METHODS AND ANALYSIS: We will use a sequential mixed-methods study design to investigate the multiple factors (familial, social and occupational situation, critical life events, general risk behaviour, mental and physical health, satisfaction with life) that shape individual ATS use pathways. A systematic literature review will be performed to provide an overview of the current academic literature on the topic. In module 1, qualitative semistructured interviews (n=ATS users and non-users) will be conducted to explore individual experiences of, and perspectives on, dynamics of change in stimulant consumption patterns. In module 2, structured questionnaires (n=2000 ATS users and non-users) will be administered via tablet computers to validate and enhance the generalisability of the interview findings. Data integration will take place at two key points. First, during the study, where the findings from the first qualitative interviews will inform the design of the structured questionnaire. Second, at the end of the study, where mixed methods data will be brought together to generate an in-depth, contextualised understanding of the research topic. ETHICS AND DISSEMINATION: The study has been approved by the respective responsible ethics committee in each participating country. Data will be treated confidentially to ensure participants' anonymity. Findings will be disseminated in peer-reviewed scientific journals, national and international conferences, and in briefings for policy and practice.

RESUMEN

Healthcare for mental disorders is a big challenge for the German healthcare system. In cases of comorbid mental diseases, patients suffer from an especially high burden of disease. So far, innovative care models for collaborative and stepped care have only been investigated with respect to their effectiveness for single mental disorders.The project "Collaborative and Stepped Care in Mental Health by Overcoming Treatment Sector Barriers" (COMET), which is being carried out by the Hamburg Network for Health Services Research (HAM-NET) from 2017 until 2020, examines an innovative, guideline-based healthcare model for the improvement of healthcare for patients with mental illnesses and their potential comorbidities. In this article this new stepped and collaborative care model for patients in primary care that integrates general practitioners, psychiatrists, psychotherapists, and hospitals is presented. For the implementation and facilitation of the model, guideline-based treatment pathways, a tablet-based computer program for screening, diagnostic and guideline-based treatment recommendations, as well as a web-based transferal platform were developed.The results of this project on the effectiveness and efficacy of the model can help determine if the model can be implemented in routine healthcare. This could represent a major step towards more integrated and cross-sectoral healthcare for patients with mental illnesses.

RESUMEN

BACKGROUND: Knowledge of health-related quality of life (HRQOL) of patients receiving opioid substitution treatment (OST) is limited and fragmented. The present study examines the HRQOL of a large national sample of OST patients in Germany and sociodemographic and clinical correlates. METHODS: Cross-sectional data on the HRQOL of 2176 OST patients was compared with German general population norms. Patients were recruited from 63 OST practices across Germany. To identify correlates of HRQOL, as measured with the SF-12, we performed bi- and multivariate analyses with sociodemographic and clinical variables, including patient- and clinician-reported outcomes on physical and mental health. RESULTS: Patients' HRQOL was significantly poorer than in the general population, especially their mental HRQOL. Factors associated with lower physical HRQOL were older age, longer duration of opioid dependence, hepatitis C virus infection, and HIV infection. Benzodiazepine use was associated with lower mental HRQOL, and amphetamine use with higher physical HRQOL, compared to non-use of these substances. For both mental and physical HRQOL, the factor with the strongest positive association was employment and the factors with the strongest negative associations were physical and mental health symptom severity, psychiatric diagnosis, and psychopharmacological medication. CONCLUSIONS: Compared to the general population, we found substantially lower HRQOL in OST patients, especially in their mental HRQOL. OST programs can benefit from further improvement, particularly with regard to mental health services, in order to better serve their patients' needs. Clinicians may consider the use of patient-reported outcome measures to identify patients' subjective physical and psychological needs. Further research is needed to determine if employment is a cause or consequence of improved HRQOL. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02395198 , retrospectively registered 16/03/2015.

RESUMEN

BACKGROUND AND AIMS: There is limited evidence on what shapes amphetamine-type stimulant (ATS) use trajectories. This systematic narrative review and qualitative synthesis aimed to identify individual, social and environmental influences shaping key phases in the ATS use trajectory: initiation, continuation, increase/relapse and decrease/abstinence. METHODS: MEDLINE, PsycINFO, EMBASE, and PROQUEST (social science premium collection) were searched from 2000 to 2018. Studies of any qualitative design were eligible for inclusion. Extracted data were analysed according to four key phases within drug pathways, and then cross-analysed for individual, social and environmental influences. RESULTS: Forty-four papers based on 39 unique studies were included, reporting the views of 1879 ATS users. Participants were aged 14-58 years, from varied socio-economic and demographic groups, and located in North America, Europe, Australasia and South East Asia. Reasons for initiation included: to boost performance at work and in sexual relationships, promote a sense of social 'belonging' and help manage stress. Similar reasons motivated continued use, combined with the challenge of managing withdrawal effects in long-term users. Increased tolerance and/or experiencing a critical life event contributed to an increase in use. Reasons for decrease focused on: increased awareness of the negative health impacts of long-term use, disconnecting from social networks or relationships and financial instability. CONCLUSIONS: Amphetamine-type stimulant users are a highly diverse population, and their drug use careers are shaped by a complex dynamic of individual, social and environmental factors. Tailored, joined-up interventions are needed to address users' overlapping economic, health and social care needs in order to support long-term abstinence.

RESUMEN

BACKGROUND: In Germany, about 1.4 to 2.6 million people are dependent on prescription drugs, mainly benzodiazepine derivatives and opioid analgesics. Despite this large number of affected people, studies on prescription behaviour and drug intake are scarce. There are particularly few empirical findings available with regard to elderly people age 65 and over who are disproportionally affected by prescription drug abuse. METHODS: The North German Pharmacy Computing Centre (Norddeutsches Apothekenrechenzentrum, NARZ) collects the prescription data of about 11 million citizens and covers over 80% of drug pharmacies in North Germany. Based on the data from NARZ, we evaluate person-related prescriptions of benzodiazepines, Z­drugs and opioid analgesics. By means of incremental calculations, we determine the prevalence of prescription drug use, the long-term intake, the average daily dose of these medications and present this information as a five-year trend (2006-2010). RESULTS: In 2006, 10.6% of the members of public healthcare system were prescribed at least one of the medications under study. This proportion hardly changed within the five-year span. The share of patients with benzodiazepine prescription steadily decreased from 2006 (5.5%) to 2010 (5.1%), especially among elderly people. While the prevalence of Z­drug prescriptions remained the same at about 1%, there was a slight increase in prescriptions of opioid analgesics with 5.4% in 2006 to 5.7% in 2010. The proportion of patients with long-term prescriptions decreased with regard to benzodiazepines (from 17.0 to 12.8%) and Z­drugs (from 24.3 to 21.2%), but increased for opioid analgesics (from 19.2 to 21.2%). CONCLUSION: The analytical method used in this study is an innovative epidemiological approach to evaluate person-related register data over the course of several years. Establishing a monitoring system of prescription drugs with potential for dependence may allow for a quicker identification of trends and initiation of appropriate measures.

RESUMEN

BACKGROUND: In Central Asia, there is a need to update information about the situation of people who use (opioid) drugs (PWUD), especially regarding their access to and utilization of health care services. The aim of the study was to gather information about two different groups of drug users in Kazakhstan and Kyrgyzstan. METHODS: In 2013, two groups of PWUD were recruited in Kazakhstan and in Kyrgyzstan in order to gather quantitative data via interviewer-administered questionnaires. PWUD registered with the Narcological Register were allocated to group A while non-registered PWUD were allocated to group B. Interviews were conducted in the office of the Narcological Register as well as in low-threshold facilities. Participants reported about their drug use patterns, health status, and utilization of health services as well as barriers to utilization. RESULTS: The sample consisted of N = 600 PWUD (301 registered and 299 non-registered PWUD) from Kazakhstan and N = 900 PWUD (450 registered and 450 non-registered PWUD) from Kyrgyzstan. Both groups-registered (group A) and non-registered (group B)-consisted of mainly male long-term intravenous opioid users. We found high rates of current (last 30 days) opioid use (group A up to 70%; group B up to 84%). Most PWUD were burdened with poor physical and mental health. The prevalence of infectious diseases added up to 19% (group A) or 13% (group B) regarding HIV, 56% (group A) or 30% (group B) regarding HCV, and 24% (group A) or 20% (group B) regarding tuberculosis. Registered and non-registered PWUD reported high rates (95 or 82%) of lifetime use of health services for PWUD. Drug-related services were utilized less often, especially among the non-registered PWUD (13%). The most important barriers preventing PWUD from accessing services were the belief not to need treatment, doubts about the effectiveness of treatment, mistrust of treatment regime/staff, and fear of being registered with the Narcological Register (mainly group B). CONCLUSIONS: Results show that access to the health care system for non-registered PWUD is realized mainly through low-threshold facilities. Opioid substitution treatment, which is an important pillar in the treatment of PWUD, is normally only available for those registered with the Narcological Register. Instead, access to opioid substitution treatment (especially in Kazakhstan) should be expanded and granted without prior registration, as this poses an important barrier for PWUD's utilization of drug treatment services. Further, there seems to be a need for the provision of specific and target group-related information about drug treatment services in order to reduce existing reservations among PWUD as to the necessity and effectiveness of modern drug treatment.

RESUMEN

Few studies have been carried out investigating the interdependence of family structures or interactions and excessive adolescent Internet use. In this study, we surveyed a representative German quota sample of 1,744 adolescents aged between 14 and 17 years with standardized questionnaires. Adolescents assessed their perceived own functioning in the family with the Self-Rating Scale (FB-S) of the German version of the Family Assessment Measure III, and reported on problematic Internet use with the Compulsive Internet Use Scale (CIUS). To predict problematic Internet use (CIUS summary score), we conducted a multiple stepwise linear regression analysis with the seven FB-S scales, the FB-S overall index, and gender and age as explanatory variables. For the full sample, a model with only one predictor (FB-S overall index) that summarizes the quality of family functioning produced a corrected coefficient of determination of 0.239 and explained variance of nearly 24%. t Test results for unpaired samples showed significant differences in the mean values of the FB-S scales and the FB-S overall index for comparisons of both sexes, as well as of a lower age group and higher age group. The prediction of problematic Internet use between both sexes and both age groups showed comparable findings (males: corrected coefficient of determination=0.288; females: corrected coefficient of determination=0.183; lower age group: corrected coefficient of determination=0.231; higher age group: corrected coefficient of determination=0.251), each with a single predictor (FB-S overall index). The results emphasize the importance of family functioning for the occurrence of problematic Internet use in adolescents.

RESUMEN

Excessive Internet use and Internet addiction are currently increasing in many industrial nations. Verified and validated measuring instruments could contribute to a better understanding of this still quite recent development. The aim of this survey was to investigate the psychometric properties of a German version of the Compulsive Internet Use Scale (CIUS). We surveyed a representative German quota sample of 1,723 adolescents aged between 14 and 17 years, as well as one parent each, with standardized questionnaires. In addition, adolescents and parents were asked whether the media use by the youth was considered problematic or excessive, and whether it led to arguments at home. We conducted confirmatory factor analyses (CFA) with maximum likelihood estimation to examine the factorial validity of the German CIUS, as well as reliability and correlation analyses. The results of the CFA indicate good psychometric properties for the German version of the CIUS. They appear in line with the findings for the original version of the questionnaire. Furthermore, the CIUS showed high internal consistency, and we found significant correlations between the "CIUS-summary score" and different ratings of problems with the media usage by the youth and the parents. The German version of the CIUS seems to be a valid and suitable diagnostic tool for measuring problematic to pathological Internet use.
