Current practices and perceived implementation barriers for working with alcohol prevention in occupational health services: the WIRUS OHS study

What do we know about alcohol internet interventions aimed at employees?-A scoping review

Background

Internet interventions are a promising avenue for delivering alcohol prevention to employees. The objective of this scoping review was to map all research on alcohol internet interventions aimed at employees regardless of design, to gain an overview of current evidence and identify potential knowledge gaps.

Methods

We conducted a literature search in three data bases (PsycInfo, PubMed, and Web of Science). Eligibility criteria were that (1) the study targeted employees age ≥18 years; (2) the intervention was delivered predominantly online; (3) the study focused specifically or in part on alcohol use; and (4) the study was published in English in a peer-reviewed academic journal. Two reviewers independently screened, reviewed, and extracted data.

Results

Twenty studies were included, of which 10 were randomized controlled trials, five were secondary analyses, three were feasibility trials, one was a cohort study and one described the rationale and development of an intervention. No qualitative studies were found. Randomized trials tended to show effects when interventions were compared to waitlists but not when more intensive interventions were compared to less intensive ones. We identified two design-related aspects where studies differed; (1) whether all applicants were included regardless of alcohol use level and (2) whether the intervention was explicitly framed as alcohol-focused or not. Significant recruitment problems were noted in several studies.

Conclusions

Alcohol internet interventions hold promise in delivering alcohol prevention to employees, but heterogeneity in study design and difficulties in recruitment complicate interpretation of findings.

Working with alcohol prevention in occupational health services: "knowing how" is more important than "knowing that" - the WIRUS OHS study

BACKGROUND

Alcohol consumption is a major public health challenge; the majority of employees consume alcohol regularly and a considerable proportion of employees can be characterized as risky drinkers in need of interventions. Occupational health services (OHS) are uniquely positioned for implementing alcohol prevention interventions targeting employees, but rarely do so. Studies have shown that lack of knowledge among OHS personnel is a barrier to alcohol prevention activity. This study aimed to explore OHS personnels' levels of theoretical and practical alcohol knowledge, and whether these two ways of knowing were differentially associated with alcohol prevention activity.

METHODS

In this cross-sectional study, survey data were collected from 322 OHS personnel in Norway in 2018 (response rate = 53.6%). The survey included variables of two ways of knowing (theoretical and practical) and three types of doing (intervention frequency, conducting individual interventions, and conducting group interventions). Data were analyzed with descriptive statistics, paired sample t-tests, bivariate correlations, and adjusted linear and logistic regression analyses.

RESULTS

OHS personnel rated their theoretical alcohol knowledge higher than their practical knowledge (η² = 0.33, p < 0.001). Higher reported levels of practical knowledge were associated with higher intervention frequency (b = 0.39, β = 0.60, p < 0.001) and greater likelihood of conducting individual interventions (OR = 1.60, p < .001) as well as group interventions (OR = 1.84, p < 0.001). Theoretical knowledge was not associated with conducting interventions, and there was no evidence of an interaction between the two ways of knowing in their association with doing. Sensitivity analyses did not indicate clustering effects of OHS personnel being employed within different units.

CONCLUSIONS

Different ways of knowing about alcohol among OHS personnel were dissimilarly associated with conducting alcohol prevention interventions in occupational health settings. For doing, knowing how seems to be more important than knowing that. Training programs for OHS personnel should emphasize knowledge about how to deal with alcohol-related issues and how to conduct prevention interventions, rather than focus on detrimental effects of alcohol.

Do health professionals' attitudes towards alcohol use matter for alcohol prevention efforts? Results from the WIRUS-OHS study

BACKGROUND

Use of alcohol is a major public health issue, representing the 7^th largest burden of disease in the world. Workplaces offer a unique arena for health initiatives addressing alcohol use, where occupational health services (OHS) personnel play an important role. However, we do not know if the extent of such initiatives may be influenced by personal drinking attitudes among OHS personnel. Thus, the aim of the study was to explore how drinking attitudes among OHS personnel were associated with their frequency of working with alcohol-related cases and with their views on alcohol prevention activities in the OHS.

METHODS

The WIRUS project included a cross-sectional survey of attitudes and practices among OHS personnel (n = 325) employed by Norwegian OHS services (n = 69), who informed about sociodemographic and professional characteristics, drinking attitudes, frequency of cases with alcohol-related issues, and perceptions toward the role of the OHS in primary, secondary, and tertiary alcohol prevention activities. Measures of associations were examined with linear and logistic regression models.

RESULTS

Drinking attitudes were unrelated to the frequency of working with alcohol-related cases. Physicians, psychologists, and nurses had higher frequency of working with alcohol-related cases, compared to those with other professional backgrounds (β = 0.46, p = 0.01). Drinking attitudes were also unrelated to attitudes towards primary/secondary/tertiary alcohol prevention activities in the OHS, while female OHS personnel were more positive towards increased primary alcohol prevention activities in the OHS (OR: 1.82, p < 0.05). Only marginal portions (1%-3%) of the variance in attitudes towards alcohol prevention activities in the OHS were accounted for by the models.

CONCLUSION

This study did not find evidence of associations between OHS personnel's drinking attitudes and their practices and attitudes towards alcohol prevention activities. The lack of association between OHS personnel's attitudes towards alcohol use and their attitudes and practices relating to alcohol prevention in the workplace might point towards professionalism, as personal attitudes appear not to interfere with their priorities and professional mission. Given the small amount of outcome variance explained by the tested models, other variables should be used in future studies.

Do Differences in Drinking Attitudes and Alcohol-Related Problems Explain Differences in Sick Leave? A Multilevel Analysis of 95 Work Units Within 14 Companies From the WIRUS Study

Background

Systematic reviews have shown a strong relationship between alcohol consumption and sick leave. The effect of alcohol consumption on sick leave may, however, vary according to the work environment. While attitudes toward drinking may impact sick leave, there is little research on the contribution of drinking attitudes to sick leave. Moreover, alcohol-related problems and drinking attitudes may be influenced by the broader sociocultural contexts of the organizational units where people work.

Objectives

This study aimed to explore the relationship of alcohol-related problems and drinking attitudes with sick leave while considering the nesting of employees within working units within companies.

Method

Data from the WIRUS (Workplace Interventions preventing Risky alcohol Use and Sick leave) study were linked to company-registered sick leave data for 2,560 employees from 95 different work units in public (n = 9) and private companies (n = 5) in Norway. Three-level (employee, work unit, and company) negative binomial regression models were estimated to explore the 12-month prospective association of alcohol-related problems and drinking attitudes with four measures of sick leave (one-day, short-term, long-term, and overall sick leave days). Models were adjusted for gender, age, cohabitation status, educational attainment, work position, and employment sector.

Results

We observed higher variation of one-day, short-term, and overall sick leave days between companies than between work units within companies (15, 12, and 30% vs. 0, 5, and 8%, respectively). However, neither alcohol-related problems nor drinking attitudes were associated with sick leave and, thus, those variations in sick leave were not explained by alcohol-related problems or drinking attitudes.

Conclusion

Our findings suggest company-level differences are more important than within company differences when explaining differences in sick leave. While alcohol-related problems or drinking attitudes were not associated with sick leave, future studies may need to explore the role of company policies, practices, or social norms in variations in sick leave rates.

A randomized controlled trial of the web-based drinking diary program for problem drinking in multi workplace settings

Objectives

To assess the effectiveness of a web‐based brief intervention (BI) program to record daily drinking among people with problem drinking in workplace settings.

Methods

A two‐armed, parallel‐group, randomized controlled trial were conducted at six workplaces in Japan. After obtaining written consent to participate in the study, workers with an Alcohol Use Disorders Identification Test (AUDIT) score of 8 or higher were randomly assigned into two groups. The participants allocated to the intervention group recorded their daily alcohol consumption for 4 weeks using the program, while those allocated to the control group received no intervention. Outcome measures included the amount of alcohol consumption in past 7 days using the Timeline Follow‐Back method in the program at baseline, 8th week, and 12th week and written AUDIT score at baseline and 12th week.

Results

Hundred participants were assigned to either the intervention group (n = 50) or control group (n = 50). The results of two‐way repeated measures ANOVA showed a statistically significant interaction between the group and the week factors in the two primary outcomes (number of alcohol‐free days, total drinks) and secondary outcomes (AUDIT score) (p = .04, .02, and .03, respectively). The between‐group effect sizes (Hedges' g; 95% CI) of the outcomes at 12th week were 0.53; 0.13–0.93 (total drinks), 0.44; 0.04–0.84 (AUDIT score), 0.43; 0.03–0.83 (number of alcohol‐free days).

Conclusions

The web‐based BI program for problem drinking was considered to be effective in reducing alcohol consumption and the AUDIT score in workplace settings.

Occupational health care personnel tackling alcohol overuse - an observational study of work processes and patient characteristics

Background

Overuse of alcohol is a significant risk factor for early retirement. This observational study investigated patient characteristics and work processes in occupational health care (OHC) affecting practices in tackling alcohol overuse.

Methods

The data were from 3089 patient contacts gathered for quality improvement purposes in fifteen OHC units during the years 2013–2019 in Finland. A two-proportion z-test was performed to find associations between reason for contact, and 17 other factors, and the probability of alcohol use being checked and overuse tackled.

Results

OHC personnel checked alcohol use twice as often with male patients as with female patients. Employees at risk of needing sick leave were checked for alcohol use more often (55.4, 95% confidence interval 49.2–61.6%) than those on > 30-day sick leave or working with permanent work disability (p < 0.01). Alcohol use was checked in 64.1% (59.5–68.7%) of patients while making an individual health promotion plan compared to 36.9% of those without a plan (33.1–40.6%, p < 0.0001). Patients with depression were actively checked for alcohol use, especially in cases of major depression (72.7%, 64.0–81.0%). Work processes in which OHC should have been more active in checking and tackling alcohol use included assessing the need for rehabilitation (36.5%, 32.0–41.0%) and health check-ups (HCUs) for mental reasons (43.8%, 38.1–49.4%). HCUs where alcohol overuse was detected led to brief interventions to tackle the overuse in 58.1% (43.4–72.9%) of cases.

Conclusions

The study showed factors that increased OHC personnel’s practices in checking and tackling alcohol use and work processes where the activity should be improved. Discussions about alcohol use took place more often with working-aged men than women, the younger the more. OHC personnel checked actively alcohol use with patients in danger of sick leave, patients treated for depression, while making an individual health promotion plan, and in planned HCUs with a confirmed protocol. More improvement is needed to conduct brief interventions in disability prevention processes, and especially when overuse is detected.

Willingness to Participate in Alcohol Prevention Interventions Targeting Risky Drinking Employees. The WIRUS Project

Background: The extent to which eligible individuals in a target population are willing to participate in interventions is important when evaluating the efficacy of public health interventions.

Objectives: As part of a process evaluation of an ongoing randomized controlled trial, this study aimed to identify the proportion of risky drinkers who were willing to participate in an alcohol prevention intervention in an occupational health setting, and correlates for such willingness.

Methods: Risky drinking employees from 22 companies in Norway were identified through an alcohol screening survey. Risky drinkers' (N = 779) willingness to complete a health examination and to be randomized into an alcohol prevention intervention (digital or face-to-face intervention, or control) was recorded by personnel from occupational health services. The proportion of employees who were willing to participate was assessed on 31 potential correlates (sociodemographic, alcohol-related, work-related, and lifestyle/daily activity). Adjusted (multiple logistic regression) analyses were utilized to explore associations between potential correlates and willingness to participate.

Results: Altogether, 38.1% of employees were willing to participate in prevention interventions. In the adjusted analysis, only 5 out of 31 potential correlates were significantly associated with willingness to participate. Managers were more than twice as willing to participate than workers (OR = 2.17, p < 0.01). Willing employees had less workplace decision latitude (perceived control over workplace decisions and less possibility of utilizing personal skills in the job) (OR = 0.62, p < 0.05), and were more overcommitted with exorbitant work ambition and need for approval (OR = 1.49, p < 0.05). Willing employees had to some extent less alcohol-related impaired work performance (presenteeism, OR = 0.78, p < 0.05), and they spent less time on care activities (OR = 0.84, p < 0.05).

Conclusions: Reaching four out of ten with risky drinking habits for prevention interventions strengthens the rationale for targeting this public health problem in occupational health care settings. In particular, this study suggests the importance of ensuring secure commitment among workers, who were less willing til participate than managers. Nevertheless, tailoring recruitment and implementation strategies based on easily identifiable correlates may be onerous.

Who reported having a high-strain job, low-strain job, active job and passive job? The WIRUS Screening study

Objective

The Job Demands and Control model classifies job types as active, passive, low-strain or high-strain, based on a combination of job demands and control. While studies have shown high-strain jobs to have adverse consequences for health and work participation, prognostic factors for the four job types have been less explored. The aim of this study was to assess the associations between sociodemographic factors and job descriptors and being in high-strain, low-strain, active and passive jobs.

Methods

The WIRUS Screening study targeted Norwegian employees in private and public enterprises. In this study, associations with job types among 4,487 employees were investigated with binary logistic regression analyses, adjusting for sociodemographic and job-related variables.

Results

In fully adjusted models, high-strain job was associated with female gender; lower education; shift work; and doing work outside the workplace. Low-strain job was associated with opposite scores on the same variables, and with lower job position. Active job was associated with lower age; female gender; higher levels of education; higher job position level; shift work; and not doing work outside the workplace. Passive job was associated with opposite scores on the same variables.

Conclusions

The study corroborates the role gender and education have for experiencing the job, and expands on existing knowledge on the role of job position and irregular working hours and spaces. By identifying factors associated with job types, the prevention of health problems and work disability may become be more targeted.

Sociodemographic characteristics associated with alcohol consumption and alcohol-related consequences, a latent class analysis of The Norwegian WIRUS screening study

BACKGROUND

For alcohol, the association with socioeconomic status (SES) is different than for other public health challenges - the associations are complex, and heterogeneous between socioeconomic groups. Specifically, the relationship between alcohol consumption per se and adverse health consequences seems to vary across SES. This observation is called the 'alcohol harm paradox'. This study aims to describe different patterns of alcohol use and potential problems. Next, the associations between sub-groups characterized by different patterns of alcohol use and potential problems, and age, gender, educational level, full-time employment, occupational level and income is analysed.

METHODS

Employing data from the ongoing cross-sectional WIRUS-study, N = 4311 participants were included in the present study. Individual response patterns of the ten-item Alcohol Use Disorders Identification Test (AUDIT) were analysed and latent class analysis (LCA) was used to identify latent groups. Next, the associations between the classes identified in the best fitting LCA-model and sociodemographic factors were analysed and presented.

RESULTS

We identified three classes based on the response patterns on AUDIT. Class 1 was characterised by low-level alcohol consumption and very low probability of negative alcohol-related consequences related to their alcohol consumption. Class 2 was characterised by a higher level of consumption, but despite this, class 2 also had a relatively low probability of reporting negative alcohol-related consequences. Class 3, however, was characterised by high levels of alcohol consumption, and a high probability of reporting negative consequences of their consumption. The classes identified were systematically differentially associated with the included measures of SES, with class 3 characterised by younger age, more males and lower educational attainment.

CONCLUSIONS

Our findings highlight the interconnectedness of alcohol consumption and alcohol-related consequences. Furthermore, the identified classes and SES yields further insights into to intricate relationship between various socioeconomic factors, alcohol use patterns and related negative consequences.

Effort-Reward Imbalance Is Associated With Alcohol-Related Problems. WIRUS-Screening Study

There is ample evidence of associations between a perceived stressful working environment and several health-related outcomes. To better understand potential mechanisms behind these observations some studies have focused on the relationship between effort-reward imbalance at work and alcohol consumption. So far, the findings have been inconsistent. One reason for this inconsistency might come from the focus on alcohol consumption per se, while disregarding other aspects such as adverse consequences related to the consumption of alcohol. The aim of the present study was to explore associations between perceived effort and reward, effort-reward imbalance and overcommitment, and alcohol-related problems. Using data from the alcohol screening component in the Norwegian WIRUS-project (N = 5,080), we ascertained the perceived effort, reward, effort-reward imbalance (ERI) and overcommitment using the effort-reward imbalance questionnaire. Alcohol-related problems was determined using a cut-off ≥8 on the Alcohol Use Disorder Identification Test (AUDIT). Associations were estimated using crude and adjusted logistic regression models. Covariates were age, gender and education. We found associations between different aspects of ERI and overcommitment, and alcohol-related problems. Specifically, the main analysis indicated that there was an increased odds for alcohol-related problems among those who reported high levels of ERI in conjunction with high overcommitment [adjusted OR: 1.40 (CI 95% 1.10–1.78)] compared to those with low levels of ERI and low overcommitment. Our findings suggest that ERI and overcommitment is associated with increased likelihood of alcohol-related problems. These findings indicate that individual and work-related factors should be taken into account collectively when aiming to determine the impact of psychosocial work environment on alcohol-related problems. Due to the cross-sectional nature of the present study, we are not able to determine the direction of the associations, and future studies should aim to investigate this.
