Age, period, and cohort effects on trends in outpatient addiction care utilization in the general Berlin population from 2008 to 2016.

BACKGROUND: The aim of this study was to decompose independent effects of age, period, and cohort on trends in outpatient addiction care utilization resulting from alcohol (AUD) and illicit substances use disorders (ISUD). Decomposing trends in addiction care utilization into their independent effects by age, period, and cohort may lead to a better understanding of utilization patterns. METHODS: Individuals seeking help in Berlin outpatient addiction care facilities between 2008 and 2016 with an age range of 18-81 years for AUD (n = 46,706) and 18-70 years for ISUD (n = 51,113) were standardized to the general Berlin population using data from the German Federal Statistical Office. Classification of utilization as AUD- (F10) or ISUD-related (F11, F12, F14, F15, F16, F18, F19) help-seeking was based on primary diagnoses according to the International Statistical Classification of Diseases and Related Health Problems. Age was measured in years and period as year of data collection. Cohort was defined as the mathematical difference between period and age. Age, period, and cohort analyses were conducted using the intrinsic estimator model on AUD- and ISUD-related outpatient addiction care utilization. RESULTS: Age effects on AUD-related utilization were highest in 18- to 19-year-old and in 39- to 59-year-old individuals. ISUD-related utilization declined almost continuously with increasing age. Period effects on AUD- and ISUD-related utilization were small. AUD-related utilization was highest in cohorts born from 1951 to 1986. ISUD-related utilization increased in cohorts born between 1954 and 1973 where utilization peaked, followed by a decline of the same order. CONCLUSIONS: Age and cohort effects were the strongest drivers of trends in AUD- and ISUD-related outpatient addiction care utilization. Onset of help-seeking in earlier phases of AUD development should be enhanced as well as help-seeking for AUD and ISUD in general. The highest cohort-related rates in the baby boomer and following cohorts for AUD and ISUD underline an increased demand for addiction care.

The Prognostic Role of DSM-5 Alcohol Use Disorder Severity and Age of Onset in Treatment Outcome Among Adults Aged 60.

AIMS: To investigate among older adults with DSM-5 alcohol use disorder (AUD) the relevance of (1) baseline DSM-5 AUD severity, (2) age of DSM-5 AUD onset, and (3) the interactions of DSM-5 AUD severity*treatment condition and age of DSM-5 AUD onset*treatment condition for the prediction of AUD treatment outcomes. METHODS: The international multicenter RCT "ELDERLY-Study" compared outpatient motivational enhancement therapy (4 sessions) with outpatient motivational enhancement therapy followed by community reinforcement approach for seniors (8 sessions) in adults aged 60+ with DSM-5 AUD. Baseline and 1-, 3-, and 6-month follow-up data from the German and Danish ELDERLY-sites (n = 544) were used (6-month participation rate: 75.9%). DSM-5 AUD diagnoses were obtained using the Mini International Neuropsychiatric Interview and alcohol use using Form 90. Associations between DSM-5 AUD severity and age of onset and AUD treatment outcomes were investigated using multiple logistic regression and generalized linear models. RESULTS: The sample was diverse in AUD severity (severe: 54.9%, moderate: 28.2%, mild: 16.9%) and age of onset (median: 50 years; 12-78 years). Overall, with few exceptions, neither AUD severity, nor age of onset, nor their respective interactions with treatment condition significantly predicted drinking outcomes at the different follow-ups ( P ≥ 0.05). CONCLUSIONS: No indication was found for the need to tailor treatment content according to DSM-5 AUD severity and earlier onset in older adults.

Residual alcohol use disorder symptoms after treatment predict long-term drinking outcomes in seniors with DSM-5 alcohol use disorder.

BACKGROUND: Risk of relapse within the first months after alcohol use disorder (AUD) interventions is substantial among older adults. For this vulnerable group, little information exists on how this risk is associated with residual DSM-5 AUD symptoms after treatment. AIMS: To investigate among older adults who received short-term treatment for DSM-5 AUD (1) the prediction of drinking behaviors and quality of life 12 months after treatment initiation by 6-month DSM-5 AUD symptoms, AUD severity, and AUD remission, and (2) whether these DSM-5 AUD indicators provide prognostic information beyond that gained from 6-month alcohol use (AU) status. METHODS: The international multicenter RCT "ELDERLY-Study" enrolled adults aged 60+ with DSM-5 AUD. We used data from the subsample of 323 German and Danish participants with complete DSM-5 AUD criterion information 6 months after treatment initiation (61% male; mean age = 65.5 years). AU was assessed with Form 90, DSM-5 AUD with the M.I.N.I., and quality of life with the WHOQOL-BREF. Generalized linear models were applied to investigate the associations between 6-month AUD indicators and 12-month AU and quality of life. RESULTS: Independent of AU at 6 months, having 1 (vs. no) residual AUD symptom at 6 months predicted a 12-month "slip," defined as exceeding a blood alcohol concentration of 0.05% at least once during that time (OR: 3.7, 95% CI: 1.5 to 9.0), heavy episodic drinking, and hazardous use (p < 0.05). AUD remission was associated with a lower risk of a "slip" at 12 months (p < 0.05). Failed reduction/cessation was associated with poorer physical health (Coef.: -0.4, 95% CI -0.7 to -0.1). CONCLUSION: For older adults, residual AUD symptoms in the first months after short-term treatment predict problematic AU outcomes during the first 12 months after treatment entry. Thus, residual symptoms should be addressed in this patient population during posttreatment screenings.

Changes in gambling behaviour and related problems in clients seeking help in outpatient addiction care: Results from a 36-month follow-up study in Bavaria.

BACKGROUND AND AIM: Evidence on the course of gambling disorder (GD) in clients seeking help from outpatient addiction care facilities is sparse. To close this knowledge gap, this longitudinal one-armed cohort study portrays the development of GD in help-seeking clients over a 3-year timeframe. METHODS: We investigated changes in severity of GD as well as in gambling frequency and intensity in 145 gamblers in outpatient treatment in Bavaria using generalized estimation equations (GEEs). To investigate potentially different trajectories between study participants with and without migration background (MB), additional analyses were applied with time*migration interaction. All analyses were adjusted for age, gender, education, electronic gambling machine (EGM) gambling, MB, GD, related help sought before and treatment status. RESULTS: Within the entire study population, improvements in severity of GD (reduction of 39.2%), gambling intensity (reduction of 75.6%) and gambling frequency (reduction of 77.0%) were observed between baseline and 36 months of follow-up. The declines were most pronounced between baseline and follow-up 1 and stabilized thereafter. Participants with MB improved consistently less than participants without MB. DISCUSSION AND CONCLUSION: Our study suggests that severity of GD and gambling patterns improve in the context of outpatient treatment. The beneficial results furthermore persist for 36 months after treatment termination. As clients with MB seem to profit less than clients without MB, improvements in outpatient gambling services to the specific needs of this clientele are required.

Substance use disorder and the baby boom generation: Does Berlin outpatient addiction care face a sustained change?

INTRODUCTION: The ageing of baby boomers is expected to confront addiction care with new challenges. This cohort had greater exposure to psychoactive substances in youth than earlier cohorts. In this study, we aimed to investigate whether Berlin addiction care is confronted with a sustained change in its clientele initiated by the baby boomers. METHODS: Using data from Berlin outpatient addiction care facilities, we contrasted type of primary substance use disorder and number of comorbid substance use disorders in baby boomers with an earlier and a later cohort. To isolate cohort effects, two-level random intercept regression models were applied in the overlapping age groups of the baby boomer cohort with each of the other cohorts. RESULTS: Compared with the earlier cohort, alcohol use disorder lost importance whereas illicit substance use disorder gained importance in the baby boomers. Baby boomers presented a higher number of comorbid substance use disorders than the earlier cohort. Comparing baby boomers with the later cohort, these relationships pointed in the opposite direction. DISCUSSION AND CONCLUSIONS: Outpatient addiction care faces a sustained change to more illicit and comorbid substance use disorders. With increasing life expectancy and the ageing of baby boomers marked by higher substance use than previous cohorts, older clients, who had been under-represented in outpatient addiction care, will gain relevance. Hence, addiction care has to adapt its offers to appropriately meet the changing needs of its clientele.

Stability of Posttreatment Reductions in World Health Organization (WHO) Drinking Risk Levels and Posttreatment Functioning in Older Adults with DSM-5 Alcohol Use Disorder: Secondary Data Analysis of the Elderly Study.

BACKGROUND: Studies have found that reductions in World Health Organization (WHO) drinking risk levels may be a stable outcome of treatment for alcohol use disorder (AUD) and associated with functional improvements. The aim of this study was to investigate whether posttreatment reductions in WHO drinking risk levels are stable over time among older adults and associated with a decrease in consequences of drinking and AUD symptoms and improved quality of life. METHODS: Participants. Individuals 60+ years old, suffering from DSM-5 AUD (n = 693), and seeking outpatient treatment. MEASUREMENTS: WHO drinking risk levels, prior to treatment and at all follow-up points up to 1 year after treatment start, were assessed with Form 90. Outcomes at follow-up included consequences of drinking (Drinker Inventory of Consequences), quality of life (WHOQOL-BREF), and DSM-5 AUD symptoms (Mini International Neuropsychiatric Interview). Logistic regression and linear mixed models were used to examine the probability of maintaining risk-level reductions at follow-up and the association between risk-level reductions and outcomes, respectively. RESULTS: Reductions in risk levels were maintained over time (at least 1 level: OR 5.39, 95% CI 3.43, 8.47; at least 2 levels: OR 9.30, 95% CI 6.14, 14.07). Reductions were associated with reduced consequences of drinking and number of AUD symptoms, and minor, but statistically significant, improvements in quality of life. CONCLUSIONS: Maintaining reductions in WHO risk levels appears achievable for older adults seeking treatment for AUD. The small reduction of AUD symptoms and improvement of quality of life indicates that these reductions may not be adequate as the only treatment goal.

Gambling disorder in the context of outpatient counselling and treatment: Background and design of a prospective German cohort study.

OBJECTIVE: The prospective naturalistic study 'Katamnese-Studie' conducted between 2014 and 2019 gathers evidence on the course of gambling disorder in German routine outpatient addiction care. This study elucidates design and methodological advantages and caveats of the study. METHODS: Participants of the multi-centre cohort received written questionnaires at admission and at 6-, 12-, 24- and 36-month follow-up to assess socio-demographic data, gambling behaviour, gambling-related consequences and care offers sought. Subsequently, self-reports were linked to client-individual routine documentation for the German Addiction Care Statistical Service. Furthermore, employees of participating outpatient addiction care facilities were surveyed regarding experiences with and attitudes towards gambling disorder. Multivariate longitudinal regression models will portray changes in the severity of gambling disorder and gambling behaviour and explore associated client- and care-related factors. CONCLUSION: The 'Katamnese-Studie' covers the whole spectrum of outpatient gambling care. Keeping the design-related caveats in mind (reliability of self-reports, loss-to-follow-up and issues regarding causal inference), the study is anticipated to draw a comprehensive picture of routine outpatient gambling care and key factors related to sustained remission. In the medium term, this information might support the development and subpopulation-specific adaptation of recommendations on how to structure process and content of outpatient gambling care.

Impact of comorbid mental disorders on outcomes of brief outpatient treatment for DSM-5 alcohol use disorder in older adults.

BACKGROUND: Relatively little is known about the prognostic value of comorbid mental disorders in alcohol use disorder (AUD) treatment for older adults (OA). AIMS: This article aimed to investigate 1) the impact of current unipolar mood and anxiety disorders in AUD treatment success in OA, 2) the timing of this putative comorbidity impact over six months, and 3) the role of treatment length in comorbidity effects. METHODS: We analyzed baseline and one-, three-, and six-month follow-up data from the international multicenter RCT "ELDERLY-Study" (baseline n = 693, median age: 64.0 years) using mixed effects regression models. In adults aged 60+ with DSM-5 AUD "ELDERLY" compared outpatient motivational enhancement therapy (MET, four sessions) with outpatient MET plus community reinforcement approach for seniors (MET & CRA-S; up to 12 sessions). Aiming for abstinence or minimal alcohol use (AU), both conditions included CBT-elements. We assessed AU with Form 90, and mental disorders with the Mini International Neuropsychiatric Interview (M.I.N.I.). RESULTS: Mood-related disorders were associated with more drinks per day at baseline and greater reductions in drinks per day at one and six months (main effect mood disorder: Coef. 2.1, 95% CI 0.6-3.6; one month interaction effect: Coef. -1.9, 95% CI -3.3- -0.5; six months interaction effect: Coef. -2.1, 95% CI -3.5 - -0.6). These results were replicated within MET & CRA-S but not within MET. CONCLUSION: Comorbid mental disorders had modest effects on short-term outpatient treatment outcomes. OA with AUD and unipolar mood-related disorders may profit from short interventions based on motivational interviewing and CBT-elements. ClinicalTrials.gov:NCT02084173.

Gamblers' attitudes towards money and their relationship to gambling disorder among young men.

BACKGROUND AND AIMS: Money plays a central role in gambling, and understanding the different attitudes of gamblers towards it might benefit both prevention and treatment of gambling-related problems. This study describes the development of a new German measure of attitudes to money and the differences in these attitudes between male non-gamblers, occasional, frequent and problem gamblers. Furthermore, it investigates the cross-sectional and longitudinal associations between attitudes towards money and the severity of gambling disorder. METHODS: An online study was conducted among 2,584 men aged 18-25 years, recruited via the Munich citizen registry. Additionally, a sample of n = 105 Facebook users was included in part of the analyses. Frequent and problem gamblers were invited to a 12-month follow-up. Apart from gambling participation and related problems, the questionnaire included items from existing scales measuring attitudes to money. RESULTS: Three factors underlying a new 12-item German Scale of Money Attitudes (SMAG) were identified: success, budgeting and evil. Compared with other groups, participants reporting any gambling problems scored highest in success and lowest in budgeting. Budgeting was associated with gambling-related problems in both cross-sectional and longitudinal analyses and strengthened the relationship between associating money with success and gambling disorder. DISCUSSION: For problem gamblers, money is important as a personal symbol of success. This attitude has an especially negative effect on gambling-related problems in individuals who handle money irresponsibly. Spending and winning money might play an important role in maintaining self-esteem among gamblers and thus hinder their attempts to quit.
