Patient Perspectives on Blended Internet-Based and Face-to-Face Cognitive Behavioral Therapy for Alcohol Use Disorder: Qualitative Study

BACKGROUND

Harmful alcohol consumption has been identified as a major contributor to disease, mortality, and social harm, accounting for 5.3% of worldwide deaths annually. In Denmark, an estimated 150,000 people suffer from alcohol use disorder (AUD), but a low proportion seek treatment due to person- and treatment-related barriers. Internet-based cognitive behavioral therapy (iCBT) has shown positive effects on the treatment gap, with patients reporting benefits such as increased knowledge and flexibility. However, there is a lack of research on blended cognitive behavioral therapy (bCBT), which combines face-to-face CBT (FtF CBT) and iCBT for AUD.

OBJECTIVE

This study aims to investigate user experiences of bCBT. More specifically, it seeks to explore the advantages and disadvantages that users have experienced with bCBT for AUD, as well as their motivations for choosing this treatment format.

METHODS

A total of 30 patients who had participated in the Blend-A (Blending Internet Treatment into Conventional Face-to-Face Treatment for AUD) study and received the intervention were contacted and offered the opportunity to participate in semistructured individual telephone interviews. Of these, 12 patients consented to participate. Furthermore, an additional participant was approached at a municipal clinic and agreed to engage in an individual FtF interview. Thus, the final sample consisted of 13 patients. The interviews explored their background, experiences with digital technology, motivations for choosing internet-based treatment, and experiences with the program during AUD treatment. The interviews were audio-recorded and transcribed in full length and analyzed using thematic analysis. All data were anonymized and securely stored.

RESULTS

We found that users experienced several advantages of iCBT over a larger part of the treatment course, including increased anonymity and privacy. Most importantly, it offered flexibility, allowing patients to focus on their rehabilitation process at their own pace. Patients appreciated the availability of written text in the online program, finding it helpful for gaining knowledge and understanding of AUD and its impact on the individual with the condition. They emphasized how the assignments helped them fully engage in treatment by first acknowledging their problem with alcohol and then dedicating time to self-reflection before FtF sessions, allowing for more in-depth discussions with the therapist. They also appreciated the reminders, which motivated them to complete their assignments.

CONCLUSIONS

Overall, patients perceived more benefits than disadvantages in using bCBT. Essentially, bCBT offers a form of assisted autonomy that cannot be fully achieved through iCBT or FtF CBT alone. It is only through their combination that patients can fully appreciate the benefits of the treatment, as they have time for self-reflection, with guidance from the therapist between FtF CBT sessions.

Potential factors affecting the impact of community reinforcement and family training. Secondary analysis of an RCT

BACKGROUND

In addition to increasing the quality of life among concerned significant others (CSOs), Community Reinforcement and Family training (CRAFT) aim at helping CSOs motivate treatment-refusing identified patients (IPs) into treatment through a positive reinforcement process. The aim of the present study was to investigate if the following factors, measured at baseline, have an influence on IP future treatment engagement (1) Type of relation between CSO and the IP (2) The amount of time the CSO spend with the IP (3) if the IP knows that the CSOs seeks help, and (4) The CSO's own alcohol use.

METHODS

A secondary analysis from the Danish CRAFT study. CSOs completed a self-administered questionnaire at baseline, after three months, and six months. To investigate the relationship between the four variables and treatment engagement, logistic regression was used.

RESULTS

CSO's relation to the IP, the frequency of contact between the CSO and the IP, and the CSO's AUDIT score at the time of the baseline interview were not associated with the IP's treatment engagement. If CSO at baseline had informed the IP that the CSO participated in CRAFT, odds for IP treatment engagement were significantly higher (adjusted OR [(CI)] = 2.29 [1.13; 4.63] (p < 0.05), relative to if IP not being informed.

CONCLUSIONS

CRAFT has a higher impact on the likelihood for treatment seeking, if the CSOs inform the IP about his or her own help seeking in order to change the situation. The underlying mechanism behind this is needs further investigations.

The associations between public stigma and support for others' help-seeking for alcohol use disorder: a cross sectional study in the general Danish population

BACKGROUND

A minority of all individuals with alcohol use disorders (AUD) seek treatment, where stigma is one prominent barrier. Social support is important to facilitate health and increase treatment-seeking. Whether there is an association between stigma and attitudes towards others' help-seeking for AUD is unknown. The aim of this study was to investigate the associations between stigma and support towards others' help-seeking for AUD, also to explore possible gender differences.

METHOD

Cross-sectional study, n = 2895, including Danish adults aged 30-65 in the general population. Year 2020, an online questionnaire was administrated, which covered demographics, attitudes towards others' help-seeking for AUD, and stigma measured with the Difference, Disdain & Blame Scales. Analyses were performed with Restricted Cubic Spline models, and odds ratios were calculated.

RESULTS

Lower level of stigma was associated with a higher probability for endorsing an "active support strategy". Level of stigma was not associated with "not knowing what to say or do" or "sharing my concern with others". There were few gender differences: among men, higher level of stigma was associated with a higher probability of "avoidance". Among women, lower level of stigma was associated with a lower probability of "avoidance".

CONCLUSION

There is a clear association between stigma and attitudes towards supporting others' help-seeking for AUD. The results highlight the need to reduce stigma and promote engagement towards others' treatment-seeking.

Acceptability Among Frontline Staff Toward Distributing an Anonymous Alcohol Survey in Emergency Departments: A Mixed Methods Study

ABSTRACT

Emergency departments (EDs) serve as the front line when patients encounter the hospital system. Limited data are available of patients' alcohol habits collected during Danish ED visits, and no studies have, to our knowledge, examined frontline staffs' (registered nurses and medical secretaries) acceptability to deliver anonymous alcohol surveys to patients. We aimed at examining the proportion of survey respondents and the prevalence of patients' alcohol habits and also exploring frontline staff acceptability of the distribution of an anonymous survey regarding patients' alcohol habits in EDs. Intendedly, all eligible patients ≥18 years old entering two EDs in March 2019 should receive a survey based on the Alcohol Use Disorder Identification Test. The study was an explanatory, sequential, mixed methods design, and results were analyzed with descriptive statistics and a deductive content analysis based on the theoretical framework of acceptability. In total, 15% (n = 1,305) of the total 8,679 patients in the EDs returned the survey. Qualitative analysis of interviews (n = 31) with staff showed that they had been reluctant to distribute the survey primarily because of ethical concerns of anonymity, freedom of choice, and being nonjudgmental toward patients. Hence, patients with no obvious alcohol problems were more likely to receive the survey. Still, we found that 23% of the respondents had an Alcohol Use Disorder Identification Test score ≥ 8. Results indicate that frontline staffs' recognition of patients' alcohol use is inadequate, and findings show a low degree of acceptability among staff to deliver an anonymous survey, which is in line with earlier described barriers toward screening activities in EDs.

The impact of an annual mass media campaign on treatment seeking for alcohol use disorders in the Danish population: An interrupted time-series analysis

INTRODUCTION

A minority of individuals with alcohol use disorder (AUD) seek treatment. In Denmark, a mass media campaign, "RESPEKT", aiming to increase treatment seeking, has been broadcasted nationwide since 2015. The campaign is unique from an international perspective. Similar interventions have, up until now, not been scientifically evaluated.

AIM

To investigate whether there was an association between campaign periods and treatment seeking for AUD. A secondary aim was to investigate possible gender differences. The hypotheses were that treatment seeking would increase during the campaign periods, and that men would increase their treatment seeking more compared to women.

METHOD

Study design: Interrupted time-series analysis.

PARTICIPANTS

Adults aged 18 years and above in the Danish population seeking AUD treatment.

EXPOSURE

Campaign periods year 2015-2018.

OUTCOME

Changes in treatment seeking defined as treatment entry respectively filled prescription of AUD pharmacotherapy.

DATA

National Alcohol Treatment Register on treatment entries for specialist addiction care and National Prescription Registry for filled prescriptions on AUD pharmacotherapies 2013-2018.

ANALYSIS

Segmented negative binomial regression, including the full cohort and stratified by sex.

RESULTS

The results show no association between campaign periods and treatment seeking. Nor were there any gender differences in treatment seeking. The hypotheses were not confirmed.

CONCLUSION

The campaign periods showed no association with treatment seeking. Eventual future campaigns should possibly focus on earlier steps of the treatment seeking process, as problem recognition, to increase treatment seeking. There is a great need to develop other ways to narrow the treatment gap for AUD.

Prognostic Importance of Atrial Fibrillation and Anticoagulation in Alcoholic Versus Dilated Cardiomyopathy

AIMS

Limited data exist to describe the prognostic impact of atrial fibrillation (AF) and oral anticoagulation on patients with alcoholic cardiomyopathy (ACM) compared with dilated cardiomyopathy (DCM) and were investigated in this study.

METHODS

Using Danish nationwide registries, a cohort analysis was conducted to assess the prognostic differences for patients with a first diagnosis of ACM versus DCM with and without AF 1994-2018 (followed until end 2019). Our study also assessed differences in mortality following initiation of anticoagulation in both populations.

RESULTS

Totally, 1237 patients with ACM (33% with AF) and 17,211 individuals with DCM (33% with AF) were included. Those with ACM were more often men (89 versus 71%) and younger than patients with DCM (mean age 56 versus 64 years). Cumulative 5-year mortality was greater among patients with ACM, compared with DCM, regardless of AF (ACM with AF 49% [95% CI: 44-54%], ACM without AF 48% [45-53%], DCM with AF 41% [39-42%], DCM without AF 30% [29-31%], P < 0.0001). The prognosis associated with AF was statistically significantly different in people with ACM and DCM (adjusted hazards ratio 0.85 [95% CI: 0.74-0.98] versus 1.04 [1.00-1.09] in ACM and DCM, P < 0.0001). The mortality associated with oral anticoagulation was similar in ACM and DCM (hazards ratio 0.81 [0.61-1.07] versus 0.87 [0.80-0.94], P = 0.49).

CONCLUSIONS

Patients with ACM had a worse prognosis when compared with patients with DCM, but this did not appear to be driven by AF. Patients with ACM were observed to have similar associated risk benefits of oral anticoagulation as DCM.

Identification of clinical factors related to prediction of alcohol use disorder from electronic health records using feature selection methods

BACKGROUND

High dimensionality in electronic health records (EHR) causes a significant computational problem for any systematic search for predictive, diagnostic, or prognostic patterns. Feature selection (FS) methods have been indicated to be effective in feature reduction as well as in identifying risk factors related to prediction of clinical disorders. This paper examines the prediction of patients with alcohol use disorder (AUD) using machine learning (ML) and attempts to identify risk factors related to the diagnosis of AUD.

METHODS

A FS framework consisting of two operational levels, base selectors and ensemble selectors. The first level consists of five FS methods: three filter methods, one wrapper method, and one embedded method. Base selector outputs are aggregated to develop four ensemble FS methods. The outputs of FS method were then fed into three ML algorithms: support vector machine (SVM), K-nearest neighbor (KNN), and random forest (RF) to compare and identify the best feature subset for the prediction of AUD from EHRs.

RESULTS

In terms of feature reduction, the embedded FS method could significantly reduce the number of features from 361 to 131. In terms of classification performance, RF based on 272 features selected by our proposed ensemble method (Union FS) with the highest accuracy in predicting patients with AUD, 96%, outperformed all other models in terms of AUROC, AUPRC, Precision, Recall, and F1-Score. Considering the limitations of embedded and wrapper methods, the best overall performance was achieved by our proposed Union Filter FS, which reduced the number of features to 223 and improved Precision, Recall, and F1-Score in RF from 0.77, 0.65, and 0.71 to 0.87, 0.81, and 0.84, respectively. Our findings indicate that, besides gender, age, and length of stay at the hospital, diagnosis related to digestive organs, bones, muscles and connective tissue, and the nervous systems are important clinical factors related to the prediction of patients with AUD.

CONCLUSION

Our proposed FS method could improve the classification performance significantly. It could identify clinical factors related to prediction of AUD from EHRs, thereby effectively helping clinical staff to identify and treat AUD patients and improving medical knowledge of the AUD condition. Moreover, the diversity of features among female and male patients as well as gender disparity were investigated using FS methods and ML techniques.

Primary Outcome from a cluster-randomized trial of three formats for delivering Community Reinforcement and Family Training (CRAFT) to the significant others of problem drinkers

BACKGROUND

Community Reinforcement and Family Training (CRAFT) is an intervention designed to help the concerned significant others (CSOs) of people with alcohol problems who are reluctant to seek treatment. It aims to improve the well-being of CSOs and teach them how to change their behavior in order to positively influence the "identified patient" (IP) to seek treatment.

METHODS

The aim of the present pragmatic cluster-randomized trial was to compare the effectiveness of three formats for delivering CRAFT in real life settings: group sessions, individual sessions, and written material only (control group). Eighteen public treatment centers for alcohol use disorders were randomly assigned to deliver CRAFT in one of the three formats as part of their daily clinical routine. CSOs were recruited via pamphlets, general practitioners, and advertisements on social media. Trained clinicians delivered CRAFT in individual and group format, and self-administered CRAFT was limited to handing out a self-help book. The primary outcome was treatment engagement of the IP after three months.

RESULTS

A total of 249 CSOs were found to be eligible and randomly assigned to receive CRAFT delivered in group, individual, or self-administered format. The three-month follow-up rate was 60%. At three months follow-up, 29% (n = 32) of the CSOs who received group/individual CRAFT reported that their IP had engaged in treatment. The corresponding rate for the CSOs who received self-administered CRAFT was lower (15%; n = 5) but did not differ significantly from the other group of CSOs (Odds ratio (OR) = 2.27 (95% CI: 0.80, 6.41)).

CONCLUSION

We hypothesized that CSOs receiving CRAFT in a group format would improve the most, but although our findings pointed in this direction, the differences were not statistically significant.

Why treatment is not an option: Treatment naïve individuals, suffering from alcohol use disorders’ narratives about alcohol use and treatment seeking

Aims: To investigate the narratives of in- and outpatients at mental health and somatic hospitals, who suffer from alcohol use disorders (AUD) but have never sought AUD treatment. More specifically, to understand how the individuals view their alcohol use and explore their reasons for not seeking treatment. Methods: Individuals suffering from AUD were recruited at somatic and mental health hospitals. The study was qualitative, based on semi-structured individual interviews. A narrative analysis was performed. A total of six patients participated: three recruited at a mental health hospital, three from a somatic hospital. Results: The individuals described how heavy alcohol use had always characterised their lives; it was part of their surroundings and it added to their quality of life. Two narrative forms within the individuals’ stories were identified, in which treatment was considered either as a positive option for others but not relevant for themselves, or as representing a threat to the individuals’ autonomy. The participants expressed that they did not believe treatment was relevant for them, and if necessary, they preferred to deal with their heavy drinking themselves. Conclusions: Our findings indicate that a broad focus is needed if relatively more individuals suffering from AUD should seek treatment, since they – in spite of clearly suffering from AUD – nevertheless see themselves as heavy drinkers and have not even thought of seeking treatment. Thus, it is not (only) a question about the attractiveness of the treatment offer or due to lack of knowledge about treatment options that patients suffering from AUD do not seek treatment.

Hazardous drinking and violence-related hospitalizations in the Danish general population: A historical cohort study

BACKGROUND

It is well documented by case-control and case-crossover studies that hazardous drinking and the risk of experiencing violence-related injuries are related. The present study investigated this relationship in a cohort of general population survey respondents in Denmark using subsequent hospital admissions for violence.

METHODS

The cohort consisted of participants in the 2011 Danish national survey on alcohol and drugs (N = 5126). Survey responses were used to identify those with hazardous alcohol use. Register data on the cohort's hospital admissions for violence from 2010 through 2018 served as the outcome. The relationship between respondents' hazardous drinking and counts of subsequent hospital admissions was investigated using a Poisson regression model.

RESULTS

After controlling for confounding, respondents with hazardous consumption (Alcohol Use Disorders Identification Test Consumption [AUDIT-C] cut off: 5 points) had an increased rate of hospital admissions for violence, with an incidence rate ratio (IRR) of 2.28 (95% CI: 1.16-4.50) compared to respondents without hazardous alcohol use. Each additional AUDIT-C point was associated with a 20% increase in the incidence rate for violence-related admission (IRR=1.20, 95% CI: 1.06-1.37). Furthermore, interaction analyses showed a significant interaction between gender and AUDIT-C score on hospital admissions for violence (IRR=0.69, 95% CI: 0.53-0.90).

CONCLUSIONS

Results provide evidence that hazardous alcohol use is associated with subsequent hospital admissions for violence in the Danish general population and that gender moderates this relationship.

An Ethnographic study of unhealthy alcohol use in a Danish Emergency Department

Background

Emergency Departments (EDs) are important arenas for the detection of unhealthy substance use. Screening, Brief Intervention, and Referral to Treatment (SBIRT) for unhealthy alcohol use has been used in some ED settings with funding support from external sources. However, widespread sustained implementation is uncommon, and research aimed at understanding culture as a determinant for implementation is lacking. This study aims to explore cultural practices concerning the handling of patients with unhealthy alcohol use admitted to an ED.

Methods

An ethnographic study was conducted in an ED in the Capital Region of Denmark. The data consists of participant observations of Health Care Professionals (HCPs) and semi-structured interviews with nurses. Data was collected from July 2018 to February 2020. A cultural analysis was performed by using Qualitative Content Analysis as an analytic tool.

Results

150 h of observation and 11 interviews were conducted. Three themes emerged from the analysis: (1) Setting the scene describes how subthemes “flow,” “risky environment,” and “physical spaces and artefacts” are a part of the contextual environment of an ED, and their implications for patients with unhealthy alcohol use, such as placement in certain rooms; (2) The encounter presents how patients’ and HCPs’ encounters unfold in everyday practice. Subtheme “Professional differences” showcases how nurses and doctors address patients’ alcohol habits differently, and how they do not necessarily act on the information provided, due to several factors. These factors are shown in remaining sub-themes “gut-feeling vs. clinical parameters,” “ethical reasoning,” and “from compliance to zero-tolerance”; and (3) Collective repertoires shows how language shapes the perception of patients with unhealthy alcohol use, which may cause stigma and stereotyping. Subthemes are “occupiers” and “alcoholic or party animal?”.

Conclusions

Unhealthy alcohol use in the ED is entangled in complex cultural networks. Patients with severe and easily recognizable unhealthy alcohol use—characterized by an alcohol diagnosis in the electronic medical record, intoxication, or unwanted behavior—shape the general approach and attitude to unhealthy alcohol use. Consequently, from a prevention perspective, this means that patients with less apparent unhealthy alcohol use tend to be overlooked or neglected, which calls for a systematic screening approach.

Estimating perceived parental substance use disorder: Using register data to adjust for non-participation in survey research

AIMS

To estimate the prevalence of parental substance use disorder (PSUD) in the general population based on young adults' reports adjusted for non-participation using register-based indicators of PSUD.

DESIGN

A national sample survey study combined with a retrospective register-based study. Setting Denmark. Participants 10,414 young people (aged 15-25 years) invited to two national sample surveys in 2014 and 2015 (5,755 participants and 4,659 non-participants).

MEASUREMENTS

A crude prevalence of PSUD was calculated based on participants' reports. Parental data from medical, mortality, prescription, and treatment registers (from the young adults' birth until the time of the surveys) were used to estimate a register-based prevalence of PSUD for both participants and non-participants. Differences between participants and non-participants were analysed using bivariate comparisons. Inverse probability weighting was used to adjust for bias due to non-participation. The crude prevalence of PSUD based on survey data was adjusted using the ratio of incidence proportion of the register-based PSUD compared with the survey-based PSUD.

FINDINGS

A total of 731 (12.7%) of the 5,755 survey participants reported PSUD. Register-based PSUD was more common among non-participants (856/4,659; 18.4%) compared with participants (738/5,755; 12.8%, OR = 1.53, 95% CI 1.38-1.70). The adjusted estimate of the survey-based PSUD increased by 2.5 percentage points, from 12.7% to 15.2%.

CONCLUSIONS

In the absence of register data, youth-reported PSUD is likely to underestimate the number of young people experiencing PSUD.

History of healthcare use and disease burden in older adults with different levels of alcohol use. A register-based cohort study

BACKGROUND

Only a minority of individuals with problematic alcohol use ever seek alcohol treatment. Knowledge of general help-seeking behavior in the healthcare system can identify possibilities for prevention and intervention.

METHOD

The current study describes healthcare use, burden of disease, and prior morbidities over a 15-year period by current alcohol use behavior among Danish adults aged 60-70. The Danish National Health Survey 2013 and the baseline assessment of the Elderly Study (2014-2016) were linked to Danish national registers to collect annual information on healthcare use and morbidity for the 15 years prior to inclusion. Participants from the 3 largest Danish municipalities were divided into 4 groups with varying drinking patterns and no recent treatment [12-month abstinent (n = 691), low-risk drinkers (n = 1978), moderate-risk drinkers (n = 602), and high-risk drinkers (n = 467)], and a group of treatment-seeking individuals with a 12-month DSM-5 alcohol use disorder (AUD; n=262). Negative binomial regression models were utilized to compare rates of healthcare use and logistic regressions were used to compare odds of diagnoses.

RESULTS

Low-, moderate-, and high-risk drinkers had similar rates of past healthcare utilization (low-risk mean yearly number of contacts for primary care 7.50 (yearly range 6.25-8.45), outpatient care 0.80 (0.41-1.32) and inpatient care 0.13 (0.10-0.21)). Higher rates were observed for both the 12-month abstinent group (adjusted RR = 1.16-1.26) and the group with AUD (ARR = 1.40-1.60) compared to the group with low-risk alcohol consumption. Individuals with AUD had higher odds of previous liver disease (adjusted OR = 6.30), ulcer disease (AOR = 2.83), and peripheral vascular disease (AOR 2.71). Twelve-month abstinence was associated with higher odds of diabetes (AOR = 1.97) and ulcer disease (AOR = 2.10).

CONCLUSIONS

Looking back in time, we found that older adults had regular healthcare contacts, with those who received treatment for AUD having had the highest contact frequency and prevalence of alcohol-related diseases. Thus, healthcare settings are suitable locations for efforts at AUD prevention and intervention.

Implementation of AUDIT in the treatment planning process for alcohol use disorder in Greenland

INTRODUCTION

The aim was to describe the treatment-seeking population with alcohol use disorder by means of data from the AUDIT questionnaire at referral and to evaluate and discuss if this information can be of use in treatment and service planning.

METHODS

Data from 2016 to 2018 were extracted from the National Database on Substance Abuse Treatment. The sample included 1281 individual treatment seekers from all over Greenland.

RESULTS

Mean age was 38.2 years (SD 12.1 years). Only 60.1% had a total AUDIT score suggesting dependency, and 15.5% had a harmful use. While most only drank 2-4 times a month, about 95% binge drank. Half reported loss of control at least weekly, and one of three had been unable to do what was expected of them, or needed a drink first thing in the morning weekly or more often. In two-third others had been concerned about the drinking. Users of cannabis had a higher AUDIT score, while gambling was unassociated to alcohol use. Substantial gender and regional differences were seen.

DISCUSSION

The AUDIT screening was found useful in individual and national treatment planning. Data suggested that particular focus should be given to women in treatment, and the service offered to the East Greenlandic population.

Polysubstance abuse among sexually abused in alcohol, drug, and gambling addiction treatment in Greenland: a cross sectional study

This study aims to investigate the association between earlier sexual abuse and polysubstance abuse among persons in alcohol, drug and gambling addiction treatment in Greenland. The study included 431 individuals treated in 2017–2019. Data on exposure (sexual abuse), outcome (polysubstance abuse), and potential confounders (age, sex, school education, further education, labour market affiliation, physical abuse and emotional abuse) were extracted from The National Database on Substance Abuse Treatment. Polysubstance abuse was defined as both smoking cannabis more than once a week and having an AUDIT score >15. Logistic regression was used to estimate odds ratios (ORs). In total, 61% reported having been sexually abused. Women were more often sexually abused and had more often been physically and emotionally abused when compared to men. Polysubstance abuse (OR 2.06, 95% CI: 1.22; 3.48) and cannabis abuse (OR 1.89, 95% CI: 1.20; 2.98), but not alcohol abuse, were more frequent in sexually abused when compared to non-victims of sexual abuse. This study found polysubstance abuse to be more frequent in sexually abused treatment seekers. It is recommended that the findings are taken into account in the planning of treatment services and in training of counsellors.

Estimating the Prevalence of Alcohol Dependence in Europe Using Routine Hospital Discharge Data: An Ecological Study

AIMS

This study aims to explore the feasibility of using routine hospital discharge data, at the level of countries within Europe, to estimate the general population prevalence of alcohol dependence (AD).

METHODS

We utilised the European Core Health Indicators data tool to extract the annual rate of hospital discharges due to any wholly attributable alcohol condition as defined by the ICD-10. For those counties with data available, we systematically searched Medline, EMBASE, PsychINFO and Google for studies reporting an estimate of the prevalence of AD from national cross-sectional surveys. We compared these prevalence estimates with those developed from prediction models based on hospital discharge data.

RESULTS

The rate of hospital discharges due to any condition from the F10 diagnostic category (mental and behavioural disorders due to alcohol) was moderately correlated with AD prevalence (r = 0.56), while the rate due to any condition from the K70 diagnostic category (alcoholic liver disease) was weakly correlated with AD prevalence (r = 0.21). Two-thirds of the estimates from cross-sectional surveys were not significantly different to those generated using the F10 discharge rate prediction model.

CONCLUSIONS

Country-level AD prevalence estimates generated using annual F10 hospital discharge rates are likely to provide information of some utility, particularly when limited other sources of information are available or when examining relative trends over time or between regions. There is, however, currently insufficient evidence to make a definitive recommendation to use hospital discharge data to estimate the absolute prevalence of AD per country in Europe.

Prevalence of problems with alcohol, marijuana and gambling among patients in a Regional Hospital in Northern Greenland: investigating the potential for brief interventions in a hospital setting

Problems with alcohol, marijuana and gambling are major public health challenges in Greenland but their prevalence in a hospital setting has not been explored. Healthcare facilities play a significant role in Greenland. One important aspect is their provision of both primary and secondary healthcare services to a small and scattered population while their potential as settings for screening for problems with alcohol, substances and gambling is an unexplored area with large public health potential. This study explored the prevalences of problems with alcohol, marijuana and gambling in a hospital and the potential for the use of a hospital as a setting for screening for alcohol, substance and gambling problems. Patients from the Northern Ilulissat Hospital filled in a self-administered questionnaire regarding their behaviour related to alcohol, marijuana and gambling. Data were weighted and compared to the nationally representative 2018 Health Survey. In the Ilulissat Survey, a large proportion were abstainers but there were still problems related to alcohol, marijuana and gambling indicating a potential for screening in a hospital setting. The results based on data from 2,554 respondents showed that prevalences of problems with alcohol, marijuana and gambling are lower in the Ilulissat Survey compared to the 2018 Health Survey.

Do the carers care? A phenomenological study of providing care for patients suffering from alcohol use disorders

Excessive alcohol consumption can have adverse effects on health, and patients who suffer from alcohol use disorders are subject to much stigmatization. Nurses are often the first point of contact when patients enter the acute medical unit, and it is pivotal that this contact establishes the basis for future collaboration. The aim of this study is to elucidate nurses' lived experience of providing care to patients suffering from alcohol use disorders. This present study has a qualitative research design, anchored in phenomenological and hermeneutical methodology as described in reflective lifeworld research. Ten in-depth, open-ended interviews with nurses working in an acute medical unit were conducted. The analysis showed that providing care to patients suffering from alcohol use disorders was a highly complex task to accomplish. This required the nurse to engage with the patient in a sensitive cooperation in order to be dealing with the intricacy of the patient's life situation and balancing care between standardized procedures and the complexity of the patients. Further, a two-sided feeling of responsibility emerged: a professional responsibility and a personal responsibility causing the provision of care as being caught between feelings of despondency and resignation. Nurses lack opportunities for being creative in determining how to provide care; instead, patients' perspectives of well-being should be taken into account and should guide the provision of a meaningful care. Nurses must call for opportunities to deviate from the firmly established procedures restraining the care of this population.

The effect of exercise as adjunctive treatment on quality of life for individuals with alcohol use disorders: a randomized controlled trial

Background

A physically active lifestyle contributes to the prevention of lifestyle diseases, promotion of physical health, and reduction of pain, among other benefits. Being physically active also promotes mental health for many individuals, in the form of improved mood, increased self-efficacy and reduced risk of depression. Alcohol-dependent individuals may experience a better quality of life when supplementing their treatment with physical exercise. This study aimed to evaluate the effect of exercise on Quality of Life among patients with alcohol use disorder in a large randomized controlled trial.

Methods

The study had three arms: Patients were allocated to (A) treatment as usual, (B) treatment as usual and supervised group exercise two days a week of one hour each, (C) treatment as usual and individual physical exercise minimum two days a week. Duration of the intervention was six months. Data on values of Quality of Life were collected at baseline (before treatment start and at time of enrollment in the study), and at follow-up (at six months after enrollment in the study) using the EQ-5D questionnaire and the EQ-VAS. The sample consisted of 117 consecutive patients, and the follow-up rate was 66.6%. Intention-to-treat analyses were conducted to evaluate the effect of exercise on quality of life.

Results

Although not statistically significant, a substantial portion of the participants in the individual exercise condition reported that they had no pain or discomfort (one of the five quality of life dimensions measured by EQ-5D questionnaire) compared to the controls at follow-up. No difference was found between the groups regarding the EQ-VAS.

Conclusion

The exercise intervention had no effect on quality of life for patients with alcohol use disorder, nor was quality of life improved across the total sample. More research in how to improve quality of life for patients with alcohol use disorder is needed.

Neighborhood Deprivation and the Effectiveness of Mobile Health Coaching to Improve Periconceptional Nutrition and Lifestyle in Women: Survey in a Large Urban Municipality in the Netherlands

BACKGROUND

In 2011, we launched the Smarter Pregnancy mobile health (mHealth) coaching program, which has shown to effectively improve inadequate nutrition and lifestyle behaviors in women before and during pregnancy. It is known that in deprived neighborhoods, risk factors for adverse pregnancy outcomes like inadequate nutrition and lifestyle behaviors accumulate. However, it has not yet been investigated whether the Smarter Pregnancy program is equally effective in women living in deprived neighborhoods.

OBJECTIVE

This paper aimed to study the associations between neighborhood deprivation and improvement of inadequate nutrition and lifestyle behaviors of women who were either contemplating pregnancy or already pregnant and subscribed to the Smarter Pregnancy program.

METHODS

We performed an additional analysis on data from women who used the Smarter Pregnancy program from 2011 to 2016. The program comprised 24 weeks of coaching on 5 nutrition and lifestyle behaviors, of which adequate intakes or lifestyle behaviors were defined as an intake of 200 grams or above of vegetables, 2 pieces of fruit, daily folic acid supplement use of 400 µg per day, and no smoking or alcohol consumption. Neighborhood deprivation was determined according to the status scores of the Netherlands Institute for Social Research. Logistic regression analyses and generalized estimating equation models were used to assess the associations between the neighborhood status score (NSS) and the improvement of inadequate nutrition and lifestyle behaviors, taking into account the behaviors at baseline. We adjusted the analyses for maternal age, body mass index, geographic origin, pregnancy status, and participation as a couple.

RESULTS

Of the 2554 women included, 521 participated with their male partner. Overall, daily vegetable intake was most frequently inadequate at the start of the program (77.72, 1985/2554). Women with a higher NSS (ie, nondeprived neighborhood) smoked less often (adjusted odds ratio [OR] 0.85; 95% CI 0.77-0.93), consumed alcohol more often (adjusted OR 1.14, 95% CI 1.04-1.24), and were less likely to complete the 24 weeks of coaching (OR 0.91, 95% CI 0.88-0.95) compared with women who lived in a neighborhood with a low NSS (ie, deprived). In the total group, the relative improvement of inadequate nutrition and lifestyle behaviors after 24 weeks of coaching was between 26% and 64%. NSS was negatively associated with this improvement, indicating that women with a higher NSS were less likely to improve inadequate nutrition and lifestyle behaviors, especially vegetable intake (adjusted OR 0.89, 95% CI 0.82-0.97).

CONCLUSIONS

The Smarter Pregnancy mHealth coaching program empowers women to improve inadequate nutrition and lifestyle behaviors. Unexpectedly, the program seemed more effective in women living in deprived neighborhoods. It is important to unravel differences in needs and behaviors of specific target groups to further tailor the mHealth program on the basis of demographic characteristics like neighborhood deprivation.

Community reinforcement and family training (CRAFT) - design of a cluster randomized controlled trial comparing individual, group and self-help interventions

BACKGROUND

Around 585,000 people in Denmark engage in harmful use of alcohol with 140,000 suffering from outright alcohol dependence. The concerned significant others (CSOs) are affected by the drinking, often suffering almost as much as the person with alcohol use disorder. Community Reinforcement and Family Training (CRAFT) is aimed at CSOs who struggle unsuccessfully, in an effort to motivate their loved ones to stop drinking and seek treatment. The aims of this study are 1) To implement CRAFT interventions into the daily routine of operating Danish alcohol treatment centers 2) To investigate whether 6-week-individual CRAFT, 6-week-open group-based CRAFT or CRAFT based on self-help material, is efficient in getting problem drinkers to seek treatment for their alcohol problems 3) To investigate which of the three interventions (individual, group or self-directed CRAFT) is the most effective and in which group of population.

METHODS

The study is a three-arm, cluster randomized controlled trial: A: individual CRAFT, group CRAFT, and CRAFT as a self-help intervention. A total of 405 concerned significant others to persons with alcohol abuse will be recruited from 24 alcohol outpatient clinics. The participants will fill out a questionnaire regarding i.e. life quality, if the drinking person entered treatment (main outcome) and satisfaction with the intervention, at baseline and after 3 and 6 months.

DISCUSSION

We expect to establish evidence as to whether CRAFT is efficient in a Danish treatment setting and whether CRAFT is most effective at individual, group or self-help material only.

Does glucagon-like peptide-1 (GLP-1) receptor agonist stimulation reduce alcohol intake in patients with alcohol dependence: study protocol of a randomised, double-blinded, placebo-controlled clinical trial

INTRODUCTION

Alcohol dependence is a major public health problem. It is underdiagnosed and undertreated. Even when treated, more than 2/3 of patients in abstinence-oriented treatment will relapse within the first year. Thus, there is an urgent need for efficacious medical treatment of alcohol dependence. Glucagon-like peptide-1 (GLP-1) receptor stimulation has proven to reduce alcohol consumption in preclinical experiments. However, the effect of GLP-1 receptor agonists in humans has to our knowledge, not yet been investigated. METHODS AND ANALYSIS: Design, participants and intervention: The effect of the once-weekly GLP-1-receptor-agonist exenatide will be investigated in a double-blinded, placebo-controlled, randomised clinical trial. 114 outpatients will be recruited and randomised to treatment with either placebo or exenatide once weekly for 26 weeks as a supplement to cognitive-behavioural therapy. The primary endpoint is reduction in number of 'heavy drinking days'. The secondary endpoints include changes in total alcohol consumption, days without consumption, changes in brain activity and function, smoking status, cognition, measures of quality of life and changes in phosphatidylethanol as a biomarker of alcohol consumption from baseline to follow-up at week 26. Status: Currently recruiting patients.

ETHICS AND DISSEMINATION

Ethical approval has been obtained. Before screening, all patients will be provided oral and written information about the trial. The study results will be disseminated by peer-review publications and conference presentations and has the potential to reveal a completely new medical treatment of alcohol dependence.

The relationship between socioeconomic status and risky drinking in Denmark: a cross-sectional general population study

BACKGROUND

Socioeconomic status (SES) is regarded as consisting of education, income and employment. However, the relationship of these three components to alcohol use behaviours, such as risky single occasion drinking (RSOD) is unclear. The aim of the present paper is to specify how the three SES components relate to RSOD in a cross-sectional survey sample of the Danish general population.

METHOD

Data from a 2011 Danish national representative survey (n = 3600) was analysed by multiple logistic regression to assess the influence of three dimensions of individual SES (education, income, employment) on RSOD.

RESULTS

Components of SES were not found to be significantly associated with RSOD independently nor in combination.

CONCLUSION

In the Danish context, SES was not associated with RSOD.

Changes in profile of patients seeking alcohol treatment and treatment outcomes following policy changes

Aim

In 2007, the legal obligation to deliver alcohol treatment to the public was transferred to the 98 municipalities of Denmark. This resulted in changes in how alcohol treatment centers in Denmark work. The aim of the present study was to describe the patient profiles and treatment outcomes in the alcohol treatment centers regarding regional variation and changes over time.

Subjects and methods

This is a descriptive, register-based study of patients enrolled in alcohol treatment centers from 2006–2014 in Denmark. Only patients above the age of 15 years and with a valid postal code were included. The sample was restricted to the patients’ first contact with the alcohol treatment register (n = 44,516).

Results

Patients who initiated treatment in the period 2006–2014 and were registered in the National Alcohol Treatment Register were primarily males (69–70%) with an average age between 46 and 49 years. Most had a vocational education (38–41%) on top of their primary education. The number of years with excessive alcohol use started out as being quite different in the five regions, but became more homogeneous over the study period. Treatment duration in the various regions followed a similar pattern, with all five of them having a similar treatment duration time of 160–230 days by 2014.

Conclusion

We found that treatment for alcohol use disorder became more homogeneous across the regions in Denmark over time and that by 2014 it was difficult to identify any differences across the country.

Alcohol screening in North Denmark Region hospitals: Frequency of screening and experiences of health professionals

Background:

Alcohol consumption is a risk factor for disease, disability and death. Approximately 20% of all hospital admissions are alcohol related. In Denmark, hospitalised patients undergo systematic health risk screenings to establish preventive initiatives if the screening detects a risk. The frequency and usability of alcohol screening and health professionals’ experiences of the screening is unknown.

Aim:

To examine the frequency and usability of alcohol screening at North Denmark Region hospitals, as well as health professionals’ experiences of screening for alcohol.

Methods:

This study consisted of an initial audit of 120 patient records from medical and surgical units at four hospitals assessing information on alcohol screening. This was followed by six focus-group interviews with health professionals (n = 20) regarding their experiences of conducting alcohol screening.

Results:

Among overall health screenings, screening for alcohol and tobacco smoking was performed most frequently (81.8% and 85%). Alcohol screening scored the lowest percentage for usability (67.7%). Hospital-based alcohol screening was perceived ambiguously leading to a schism between standardised alcohol screening and the individual needs of the patient. Health professionals described different patient types, each with their perceived needs, and screening was associated with taboo and reluctance to engage in alcohol screening of some patient groups.

Conclusion:

This study revealed factors that influence health professionals working with hospital-based alcohol screening. The variation in and complexity of alcohol screening suggests that screening practice is an ambiguous task that needs continuous reflection and development to ensure that health professionals are prepared for the task.

Risk for alcoholic liver cirrhosis after an initial hospital contact with alcohol problems: A nationwide prospective cohort study

Alcoholic liver cirrhosis is usually preceded by many years of heavy drinking, in which cessation in drinking could prevent the disease. Alcohol problems are not consistently managed in hospital patients. We followed all Danish patients with an initial hospital contact with alcohol problems (intoxication, harmful use, or dependence) during 1998-2002 for alcoholic liver cirrhosis development (n = 36,044). In this registry-based cohort, we identified predictors of the absolute risk for alcoholic liver cirrhosis. Incidence rate ratios (IRRs) were estimated as the incidence rate of alcoholic liver cirrhosis in these patients relative to the general population. Age and alcohol diagnosis were significant predictors of alcoholic liver cirrhosis risk in men and women, whereas civil status, education, and type of hospital care were not. In men, the 15-year absolute risk was 0.7% (95% confidence interval [CI], 0.4, 0.8) for 20-29 years, 5.5% (95% CI, 4.9, 6.2) for 30-39 years, 9.8% (95% CI, 9.0, 11) for 40-49 years, 8.9% (95% CI, 8.1, 9.8) for 50-59 years, 6.2% (95% CI, 5.1, 7.2) for 60-69 years, and 2.5% (95% CI, 1.7, 3.3) for 70-84 years. According to alcohol diagnosis in men, the 15-year absolute risk was 2.6% (95% CI, 2.3, 2.9) for intoxication, 7.7% (95% CI, 6.4, 7.9) for harmful use, and 8.8% (95% CI, 8.2, 9.4) for dependence. The IRR for alcoholic liver cirrhosis in the cohort relative to the general population was 11 (95% CI, 10, 12) in men and 18 (95% CI, 15, 21) in women.

CONCLUSION

Hospital patients with alcohol problems had a much greater risk for alcoholic liver cirrhosis compared to the general population. The risk was particularly increased for patients 40-59 years and for patients diagnosed with harmful use or dependence. (Hepatology 2017;65:929-937).

Andel av befolkningen i Norge med et risikofylt alkoholkonsum målt gjennom Alcohol Use Disorders Identification Test (AUDIT)

Aims

To estimate the proportion of the Norwegian population that according to the World Health Organization (WHO) guidelines should be followed up by primary health care, based on three levels of risk drinking. We also investigated the relationship between risky drinking and demographic variables (gender, age and education).

MaterialS & METHODS

– In 2012 and 2013 Statistics Norway conducted 4048 telephone interviews on a random sample of the population aged 16–79 (55.3% response rate). The Alcohol Use Disorders Identification Test (AUDIT), a screening instrument for primary health care, was used to identify potential problem drinking. We used descriptive statistics and linear regression analysis.

Results

Approximately 17% of the sample scored within the WHO-recommended limits for simple advice and/or further monitoring. Of these, 2% scored above the limit for the two most serious risk categories. Risky drinking was most prevalent among men, especially those aged 16–50. Among women, there was most risky drinking in the 16–30 age group. The regression analysis showed that age, gender and education predicted AUDIT sum scores.

Conclusion

A large proportion scored within the least serious risk group, where simple advice to cut down on alcohol is the recommended measure. This group mostly consisted of younger respondents (16–30 years), and a large majority were men (age categories 20 and older). These are individuals who do not necessarily have an alcohol problem, but are at increased risk for negative consequences such as injury during intoxication, and/or developing misuse or dependence over time.

Factors influencing whether nurses talk to somatic patients about their alcohol consumption

Aim

Many Danes drink so much that it is detrimental to their health. As they are at risk of suffering diseases which can lead to hospitalisation on somatic wards, hospitals are ideal arenas for identifying individuals whose alcohol consumption is excessive. However, literature points out that this identification rarely takes place in hospitals, and literature further suggests that the staff experience barriers to talking about alcohol use with their patients. The primary aim of this study is to identify potential factors that influence whether or not nurses talk to patients about their alcohol consumption on somatic wards. Secondarily, we wish to examine whether a screening project may affect the nurses' readiness to talk about alcohol use with their patients.

Methods

A Glaserian Grounded Theory Method was used to collect and analyse data in this qualitative study. Semi-structured one-to-one interviews were conducted with seven nurses from somatic departments at two Danish hospitals. All seven nurses were already taking part in an alcohol screening project.

Results

In the analysis of the interview material, four categories emerged: The Nurse, The Patient, The Ward and The Relay Study.

Conclusion

We identified a series of barriers and promoting factors for nurses to talk about alcohol use with patients in a hospital setting. The barriers and promoting factors emerged within four categories: The Nurse, The Patient, The Ward, and The Relay Study. The most important barrier to talking to patients about alcohol seemed to be factors within the nurses themselves, in particular personal experiences, lack of knowledge and lack of confidence. We found, however, that by participating in a screening project the nurses seemed to overcome some of these barriers.

A Smarter Pathway for Delivering Cue Exposure Therapy? The Design and Development of a Smartphone App Targeting Alcohol Use Disorder

BACKGROUND

Although the number of alcohol-related treatments in app stores is proliferating, none of them are based on a psychological framework and supported by empirical evidence. Cue exposure treatment (CET) with urge-specific coping skills (USCS) is often used in Danish treatment settings. It is an evidence-based psychological approach that focuses on promoting "confrontation with alcohol cues" as a means of reducing urges and the likelihood of relapse.

OBJECTIVE

The objective of this study was to describe the design and development of a CET-based smartphone app; an innovative delivery pathway for treating alcohol use disorder (AUD).

METHODS

The treatment is based on Monty and coworkers' manual for CET with USCS (2002). It was created by a multidisciplinary team of psychiatrists, psychologists, programmers, and graphic designers as well as patients with AUD. A database was developed for the purpose of registering and monitoring training activities. A final version of the CET app and database was developed after several user tests.

RESULTS

The final version of the CET app includes an introduction, 4 sessions featuring USCS, 8 alcohol exposure videos promoting the use of one of the USCS, and a results component providing an overview of training activities and potential progress. Real-time urges are measured before, during, and after exposure to alcohol cues and are registered in the app together with other training activity variables. Data packages are continuously sent in encrypted form to an external database and will be merged with other data (in an internal database) in the future.

CONCLUSIONS

The CET smartphone app is currently being tested at a large-scale, randomized controlled trial with the aim of clarifying whether it can be classified as an evidence-based treatment solution. The app has the potential to augment the reach of psychological treatment for AUD.

Social interactions, trust and risky alcohol consumption

BACKGROUND

The association of social capital and alcohol consumption is one of the most robust empirical findings in health economics of the past decade. However, the direction of the relationship between the two is heavily dependent on which dimension of social capital is studied and which alcohol measure is used. In this paper, we examine the effect of social interactions and generalised trust on drinking in the general Danish population survey.

METHODS

Participants (n = 2569) were recruited as part of a larger study. The double-hurdle model for the volume of alcohol consumption and the multivariate logistic model for heavy episodic drinking were estimated.

RESULTS

We found evidence that social networking with male friends, membership in voluntary organisations, and generalised trust were significantly associated with the mean volume of alcohol consumption and heavy drinking. We also observed that social support at the community level had a buffering effect against heavy episodic drinking.

CONCLUSIONS

The findings support previous findings in which social interactions and generalised trust were found to predict individuals' volume of drinking and heavy episodic drinking. However, the results varied across the indicators.

The risk of offspring developing substance use disorders when exposed to one versus two parent(s) with alcohol use disorder: A nationwide, register-based cohort study

AIM

Few population-based, family studies have examined associations between exposure to one vs. two parent(s) with alcohol use disorder (AUD) and the risk of offspring developing substance use disorder (SUD). Moreover, these studies have focused solely on the development of AUD, and not SUD, in offspring. The purpose of this study was to investigate whether exposure to one vs. two parent(s) with AUD increases the risk of offspring developing SUD.

METHODS

A population-based, cohort study was conducted in which offspring born in Denmark between 1983 and 1989 were followed through national registries until 2011. Register-based data were obtained from the: Psychiatric Central Research Register, National Patient Registry, Civil Registration System, Fertility Database, and Cause of Death Register. Adjusted hazard ratios were calculated using multivariate Cox-regression models.

FINDINGS

A total of 398,881 offspring were included in this study. Of these, 3.9% had at least one parent with AUD. Parental AUD was significantly associated with the development of SUD in offspring. Having one parent with AUD was linked to a 1.44-fold increased risk (95% CL, 1.29-1.61), while having two parents with AUD was linked to a 2.29-fold increased risk (95% CI, 1.64-3.20). No significant differences were found in relation to either parental or offspring gender.

CONCLUSIONS

Exposure to parental AUD is linked to an increased risk of offspring developing SUD. This risk is additive for offspring exposed to double parental AUD. The findings have important implications for clinical assessment and intervention strategies, as well as the management of offspring exposed to parental AUD.

Predictors of heavy drinking after liver transplantation for alcoholic liver disease in Denmark (1990-2013): a nationwide study with competing risks analyses

OBJECTIVE

Heavy drinking following liver transplantation decreases survival. Little is known of predictors of heavy drinking, which should guide clinicians identifying patients at high risk of return to heavy drinking after transplantation.

MATERIAL AND METHODS

We calculated the cumulative incidence of heavy drinking among patients transplanted for alcoholic liver disease in Denmark 1990-2013. We then analyzed pre-transplant demographic and psychiatric characteristics as predictors of post-transplant heavy drinking. Information was obtained from medical records, from nationwide registries and by interview.

RESULTS

Among 156 liver-transplanted patients, the cumulative incidence of heavy drinking was 18%, 24% and 27% after 5, 10 and 15 years post-transplant. In univariate analyses of pre-transplant predictors of heavy drinking after transplantation, younger age (p < 0.001), being retired (p = 0.007), anxiety (p = 0.04), personality disorder (p = 0.05) and no lifetime diagnosis of alcohol dependence (p = 0.03) were associated with heavy drinking after transplantation. Smoking (p = 0.06) tended to be associated, whereas depression (p = 0.7) or being married was not (p = 0.7). In the multivariate analysis, only younger age (p = 0.03), being retired (p = 0.007) and no lifetime diagnosis of alcohol dependence (p = 0.003) remained significant predictors. Heavy drinking after transplantation decreased survival beyond 5 years post-transplant (p = 0.004).

CONCLUSIONS

There is a high incidence of heavy drinking after liver transplantation for alcoholic cirrhosis in Denmark. Younger age, being retired and no lifetime diagnosis of alcohol dependence were predictors of heavy drinking after transplantation.

Relay model for recruiting alcohol dependent patients in general hospitals--a single-blind pragmatic randomized trial

Background

A large proportion of the Danish population consumes more than the officially recommended weekly amount of alcohol. Untreated alcohol use disorders lead to frequent contacts with the health care system and can be associated with considerable human and societal costs. However, only a small share of those with alcohol use disorders receives treatment. A referral model to ensure treatment for alcohol dependent patients after discharge is needed. This study evaluates the i) cost-effectiveness ii) efficacy and iii) overall impact on societal costs of the proposed referral model - The Relay Model.

Method/Design

The study is a single-blind pragmatic randomized controlled trial including patients admitted to the hospital. The study group (n = 500) will receive an intervention, and the control group (n = 500) will be referred to treatment by usual procedures. All patients complete a lifestyle questionnaire with the Alcohol Use Disorders Identification Test embedded as a case identification strategy. The primary outcome of the study will be health care expenditures 12 months after discharge. The secondary outcome will be the percentage of the target group, who 30 days after discharge, reports at the alcohol treatment clinics. In order to analyse both outcomes, difference-in-difference models will be used.

Discussion

We expect to establish evidence as to whether The Relay Model is either cost-neutral or cost-effective, compared to referral by usual procedures.

'Make it another for me and my mates': Does social capital encourage risky drinking among the Danish general population?

AIMS

The aim of this study was to examine the relationship between several indicators of social capital and risky single occasion drinking (RSOD) in a representative survey sample of the Danish general population.

METHODS

Data from the 2011 Danish national survey (n=2569) with respondents aged 15-79 years were used. Ordered logit modelling was applied to investigate the influence of social networks, social support, social participation and trust on RSOD.

RESULTS

A strong positive relationship was found between frequency of contact with male friends and RSOD between both sexes. Furthermore, social trust among men and membership in voluntary organisations among women was significantly associated with RSOD. Additionally, contact with male family members for women and active participation in religious services for both sexes were strongly and negatively correlated with RSOD.

CONCLUSIONS

Some aspects of social capital can be positively related to at-risk health behaviours, as was found for RSOD in the Danish general population.

What is wrong with non-respondents? Alcohol-, drug- and smoking-related mortality and morbidity in a 12-year follow-up study of respondents and non-respondents in the Danish Health and Morbidity Survey

AIM

Response rates in health surveys have diminished over the last two decades, making it difficult to obtain reliable information on health and health-related risk factors in different population groups. This study compared cause-specific mortality and morbidity among survey respondents and different types of non-respondents to estimate alcohol-, drug- and smoking-related mortality and morbidity among non-respondents.

DESIGN

Prospective follow-up study of respondents and non-respondents in two cross-sectional health surveys.

SETTING

Denmark.

PARTICIPANTS

A total sample of 39 540 Danish citizens aged 16 years or older.

MEASUREMENTS

Register-based information on cause-specific mortality and morbidity at the individual level was obtained for respondents (n = 28 072) and different types of non-respondents (refusals n = 8954; illness/disabled n = 731, uncontactable n = 1593). Cox proportional hazards models were used to examine differences in alcohol-, drug- and smoking-related mortality and morbidity, respectively, in a 12-year follow-up period.

FINDINGS

Overall, non-response was associated with a significantly increased hazard ratio (HR) of 1.56 [95% confidence interval (CI) = 1.36-1.78] for alcohol-related morbidity, 1.88 (95% CI = 1.38-2.57) for alcohol-related mortality, 1.55 (95% CI = 1.27-1.88) for drug-related morbidity, 3.04 (95% CI = 1.57-5.89) for drug-related mortality and 1.15 (95% CI = 1.03-1.29) for smoking-related morbidity. The hazard ratio for smoking-related mortality also tended to be higher among non-respondents compared with respondents, although no significant association was evident (HR = 1.14; 95% CI = 0.95-1.36). Uncontactable and ill/disabled non-respondents generally had a higher hazard ratio of alcohol-, drug- and smoking-related mortality and morbidity compared with refusal non-respondents.

CONCLUSION

Health survey non-respondents in Denmark have an increased hazard ratio of alcohol-, drug- and smoking-related mortality and morbidity compared with respondents, which may indicate more unfavourable health behaviours among non-respondents.

Prevalence of and potential influencing factors for alcohol dependence in Europe

Alcohol use disorders (AUDs), and alcohol dependence (AD) in particular, are prevalent and associated with a large burden of disability and mortality. The aim of this study was to estimate prevalence of AD in the European Union (EU), Iceland, Norway, and Switzerland for the year 2010, and to investigate potential influencing factors. The 1-year prevalence of AD in the EU was estimated at 3.4% among people 18-64 years of age in Europe (women 1.7%, men 5.2%), resulting in close to 11 million affected people. Taking into account all people of all ages, AD, abuse and harmful use resulted in an estimate of 23 million affected people. Prevalence of AD varied widely between European countries, and was significantly impacted by drinking cultures and social norms. Correlations with level of drinking and other drinking variables and with major known outcomes of heavy drinking, such as liver cirrhosis or injury, were moderate. These results suggest a need to rethink the definition of AUDs.

Physical activity and risk of alcohol use disorders: results from a prospective cohort study

AIMS

To examine the effect of physical activity on risk of developing alcohol use disorders in a large prospective cohort study with focus on leisure-time physical activity.

METHODS

Data came from the four examinations of the Copenhagen City Heart Study (CCHS), performed in 1976-1978, 1981-1983, 1991-1994 and 2001-2003. Information on physical activity (classified as Moderate/high, low or sedentary) and covariates was obtained through self-administered questionnaires, and information on alcohol use disorders was obtained from the Danish Hospital Discharge Register, the Danish Psychiatric Central Research Register and the Winalco database. In total, 18,359 people participated in the study, a mean follow-up time of 20.9 years. Cox proportional hazards model with delayed entry was used. Models were adjusted for available covariates (age, smoking habits, alcohol intake, education, income and cohabitation status) including updated time-dependent variables whenever possible.

RESULTS

A low or moderate/high leisure-time physical activity was associated with almost half the risk of developing alcohol use disorder compared with a sedentary leisure-time physical activity. This translates into a 1.5- to 2-fold increased risk of developing alcohol use disorder (Hazard ratios for men 1.64; 95% CI 1.29-2.10 and women 1.45; 1.01-2.09) in individuals with a sedentary leisure-time physical activity, compared with a moderate to high level. However, when stratifying by presence of other psychiatric disorders, no association was observed in women with psychiatric comorbidity. Residual confounding may have been present in this study, especially according to rough measures of income and education.

CONCLUSIONS

In both men and women, being sedentary in leisure time was a risk factor for developing an alcohol use disorder.

Increased risk of cirrhosis and hepatocellular cancer during long-term follow-up of patients with biopsy-proven NAFLD

OBJECTIVE

Our aims were to investigate the natural history of biopsy-proven non-alcoholic fatty liver disease (NAFLD) in Sweden, its associated complications, the clinical and biochemical factors associated with more advanced liver disease and the survival rate with a mean follow-up time of 27 years.

MATERIAL AND METHODS

All subjects participating in the population-based prospective cohort study Malmö Preventive Project (MPP) from 1974 to 1992 who had undergone liver biopsy with the diagnosis of NAFLD were included. The remaining MPP cohort was used as a control group. Subjects with other liver diseases and alcohol overconsumption were excluded. A panel of blood tests was analyzed in the MPP cohort. Follow-up of the NAFLD patients included studies of medical records, pathology records and mortality rates from the Swedish National Board of Health and Welfare's register until the end of 2011.

RESULTS

A total of 36 patients were diagnosed with biopsy-proven NAFLD. Median follow-up time was 27.0 years (6.32-35.3). Nine patients (25%) were diagnosed with cirrhosis and five (14%) with hepatocellular cancer, all with a previous diagnosis of cirrhosis. There were significant differences in liver function tests, insulin resistance (as homeostasis model assessment of insulin resistance) and body mass index (BMI) in patients with NAFLD compared with the control group. Mortality in the NAFLD group was significantly higher, 58.3% compared to 33.8% (p = 0.004). Hepatocellular cancer accounted for 23.8% of all deaths in the NAFLD group, compared to 0.7% (p = 0.000).

CONCLUSIONS

NAFLD can progress to advanced liver disease, including cirrhosis, with a higher than expected mortality and incidence of hepatocellular cancer.

Validation of survey information on smoking and alcohol consumption against import statistics, Greenland 1993-2010

Background

Questionnaires are widely used to obtain information on health-related behaviour, and they are more often than not the only method that can be used to assess the distribution of behaviour in subgroups of the population. No validation studies of reported consumption of tobacco or alcohol have been published from circumpolar indigenous communities.

Objective

The purpose of the study is to compare information on the consumption of tobacco and alcohol obtained from 3 population surveys in Greenland with import statistics.

Design

Estimates of consumption of cigarettes and alcohol using several different survey instruments in cross-sectional population studies from 1993–1994, 1999–2001 and 2005–2010 were compared with import statistics from the same years.

Results

For cigarettes, survey results accounted for virtually the total import. Alcohol consumption was significantly under-reported with reporting completeness ranging from 40% to 51% for different estimates of habitual weekly consumption in the 3 study periods. Including an estimate of binge drinking increased the estimated total consumption to 78% of the import.

Conclusion

Compared with import statistics, questionnaire-based population surveys capture the consumption of cigarettes well in Greenland. Consumption of alcohol is under-reported, but asking about binge episodes in addition to the usual intake considerably increased the reported intake in this population and made it more in agreement with import statistics. It is unknown to what extent these findings at the population level can be inferred to population subgroups.

Drinking contexts and the legitimacy of alcohol use: findings from a focus group study on alcohol use in Denmark

AIM

To examine the perceptions and meanings of alcohol use in Denmark with specific focus on drinking contexts.

METHODS

A qualitative study using focus group interviews. The sample consisted of five focus groups of adults with one group for each of the following age groups: 16-20; 21-34; 35-44; 45-64; and 65-82 years. The groups consisted of both men and women with five to six participants in each group (27 in total).

RESULTS

Alcohol use is perceived as legitimate in many social contexts with few being defined as inappropriate. Drinking alone is mostly associated with having alcohol-related problems, but considered legitimate if it is characterized by activity. Drinking socially plays an important role in people's considerations of legitimate use and seems to overrule the actual alcohol amount consumed. Different contexts influence different meanings of drinking with context and purpose changing with age and life stages.

CONCLUSIONS

The social drinking context is pivotal in people's perception of the legitimacy of their alcohol use, leaving the alcohol amount less important. This calls for the need to focus on and incorporate the drinking context within public health initiatives aimed at reducing high risk drinking, just as the focus on the actual amount of alcohol people consume or their frequency of use.

Alcohol use in adolescence and risk of disability pension: a 39 year follow-up of a population-based conscription survey

BACKGROUND

The role of alcohol consumption for disability pension (DP) is controversial and systematic reviews have not established causality. We aimed to assess the role of adolescent alcohol use for future DP. We wanted to find out whether an increased risk mainly would affect DP occurring early or late in life as well as whether the level of alcohol consumption and patterns of drinking contribute differently in DP receiving.

METHODOLOGY/PRINCIPAL FINDINGS

The study is a 39-year follow-up of 49 321 Swedish men born in 1949-1951 and conscripted for compulsory military service in 1969-1970. As study exposures (i) "risk use" of alcohol composed of measures related to pattern of drinking, and (ii) the level of consumption based on self-reported volume and frequency of drinking had been used. Information on DP was obtained from social insurance databases through 2008. "Risk use" of alcohol was associated with both "early DP" and "late DP", i.e. granted below and above the approximate age of 40 years, with crude hazard ratio (HR) of 2.89 (95% confidence intervals (CI) 2.47-3.38) and HR of 1.87 (95%CI: 1.74-2.02), respectively. After adjustment for covariates, HR was reduced to 1.32 (95%CI: 1.09-1.59) and 1.14 (95%CI: 1.05-1.25), respectively. Similar patterns were seen for moderate (101-250 g 100% alcohol/week) and high (>250 g) consumption, though the risk disappeared when fully adjusted.

CONCLUSIONS/SIGNIFICANCE

Alcohol use in adolescence, particularly measured as "risk use", is associated with increased risk of future DP. The association is stronger for "early DP", but remains significant even for DP granted in older ages. Therefore, pattern of drinking in adolescent should be considered an important marker for future reduced work capacity.

Internet-based brief personalized feedback intervention in a non-treatment-seeking population of adult heavy drinkers: a randomized controlled trial

Background

Internet-based interventions for heavy drinkers show promising results, but existing research is characterized by few studies in nonstudent adult populations and few comparisons with appropriate control groups.

Objective

To test whether a fully automated Internet-based brief personalized feedback intervention and a fully automated Internet-based personalized brief advice intervention in a non-treatment-seeking population of heavy drinkers would result in a reduced alcohol intake.

Methods

We conducted a 3-arm parallel randomized controlled trial in a general population-based sample of heavy drinkers. The 54,157 participants (median age of 58 years) were screened for heavy drinking. Of the 3418 participants who had a weekly alcohol consumption above 14 drinks for women and 21 drinks for men, 1380 (619 women) consented to take part in the trial and were randomly assigned to an Internet-based brief personalized feedback intervention group (normative feedback, n = 476), an Internet-based personalized brief advice intervention group (n = 450), or a nonintervention control group (n = 454). Follow-up after 6 and 12 months included 871 and 1064 participants, respectively, of all groups combined. The outcome measure was self-reported weekly alcohol consumption. We analyzed the data according to the intention-to-treat principle. To examine changes over time and to account for the multiple time measurements, we used a multilevel linear mixed model. To take attrition into account, we used multiple imputation to address missing data.

Results

The intervention effect of the Internet-based brief personalized feedback intervention, determined as the mean additional difference in changes in alcohol consumption in the Internet-based brief personalized feedback intervention compared with the control group, was –1.8 drinks/week after 6 months and –1.4 drinks/week after 12 months; these effects were nonsignificant (95% confidence interval –4.0 to 0.3 at 6 months, –3.4 to 0.6 at 12 months). The intervention effect of the Internet-based personalized brief advice intervention was –0.5 drinks/week after 6 months and –1.2 drinks/week after 12 months; these effects were nonsignificant (95% confidence interval –2.7 to 1.6 at 6 months, –3.3 to 0.9 at 12 months).

Conclusions

In this randomized controlled trial we found no evidence that an Internet-based brief personalized feedback intervention was effective in reducing drinking in an adult population of heavy drinkers.

Acceptance and expectance: Cultural norms for alcohol use in Denmark

Alcohol consumption levels in Denmark are high with the risk of increased morbidity and mortality in the population. It is suggested that people's views of "normal" use of alcohol must be the platform for formulating effective alcohol education and prevention strategies. However, little is known about the cultural norms for alcohol use. The aim of this article is to examine the perceptions of cultural norms for alcohol use in Denmark among different age groups and the similarities and differences between the groups, including examining how people construct and negotiate the cultural norms for drinking. Five focus group interviews were conducted with one group per the following age groups: 16-20; 21-34; 35-44; 45-64; and 65-82. These groups consisted of both men and women with five to six participants in each group (a total of 27). Thematic analysis was performed with the aim of developing themes that reflected the cultural norms for alcohol use. The unifying theme of this research was Danish people's acceptance and expectance of social drinking. Alcohol is widely accepted and associated with mutual expectations to drink, leading to identification of cultural influences and facilitation to drink. The social drinking context plays an important role in people's perceptions of the normality of drinking. This includes the selection of particular beverages, and regularly leads to consumption above the recommended levels for low risk to health. This calls for public health attention that promotes low risk drinking in the social context and aims to prevent and reduce serious alcohol-related harm and health problems across the population.
