A Health Technician-delivered Brief Intervention linked to AUDIT for reduction of alcohol use in Chilean primary care: a randomized controlled trial.

ABSTRACT:

Background

Because of the shortage of health professionals in Chilean primary care, Health Technicians (HT) are providing Brief Interventions (BI) for risky alcohol consumption. We compared the efficacy of two AUDIT-linked interventions provided by HTs: an informative leaflet and a BI plus leaflet.

Methods

This is a parallel-group randomized controlled trial with 1:1 randomization. Participants were identified through screening with the Alcohol Use Disorders Identification Test (AUDIT) at five primary care centers between March 2016 and July 2017. People older than 18 years at intermediate-risk (AUDIT score 8 to 15, inclusive) were randomized to receive either an HT-delivered BI (n = 174) or an informative leaflet (n = 168). Only data from participants (n = 294) who completed the 6-month assessment were analyzed. The leaflet was delivered without further advice. It contains alcohol consumption limits, a change planner, and strategies to decrease drinking. The BI was a 5-min discussion on the leaflet´s content plus normative feedback, tailored information on alcohol and health, and a change plan. The change in the AUDIT risk category six months after randomization (primary outcome) was compared among groups with a Chi-squared test. Changes in the secondary outcomes, which were scores on the AUDIT and the AUDIT´s consumption items (AUDIT-C), were compared with T-tests. Mixed-effects linear models adjusted for potential confounders. Outcome adjudicators were blinded to group assignment.

Results

At 6-month follow-up, low-risk alcohol consumption was observed in 119 (80%) participants in the BI group, and in 103 (71%) in the leaflet group, with no difference among groups ([Formula: see text] [1, N = 294] = 2.6, p = 0.1; adjusted odds ratio 0.6; 95% confidence interval [CI] 0.34, 1.05). The mean AUDIT score decreased by 5.76 points in the BI group, and by 5.07 in the leaflet group, which represents a 0.86 AUDIT point reduction attributable to the BI (secondary outcome) (T = 2.03, p = 0.043; adjusted mean difference 0.86 CI 0.06, 1.66).

Conclusions

The AUDIT-linked BI delivered by HTs was not associated with a greater reduction of risky alcohol consumption than an informative leaflet. Delivering a leaflet could be more efficient than a BI when provided by HTs; however, more research on the effectiveness of the leaflet is needed.

Project description:BackgroundAlcohol Brief Intervention (ABI) uses a motivational counselling approach to support individuals to reduce excessive alcohol consumption. There is growing evidence on ABI's use within various health care settings, although how they work and which components enhance success is largely unknown. This paper reports on the qualitative part of a mixed methods study. It explores enablers and barriers associated with alcohol reduction following an ABI. It focuses on alcohol's place within participants' lives and their personal perspectives on reducing consumption. There are a number of randomised controlled trials in this field though few ABI studies have addressed the experiences of hazardous/harmful drinkers. This study examines factors associated with alcohol reduction in harmful/hazardous drinkers following ABI.MethodsThis qualitative study was underpinned by a realist evaluation approach and involved semi-structured interviews with ten harmful or hazardous alcohol drinkers. Participants (n = 10) were from the intervention arm of a randomised controlled trial (n = 124). All had received ABI, a 20 min motivational counselling interview, six months previously, and had reduced their alcohol consumption. Interviews were recorded, transcribed verbatim and thematically analysed.ResultsParticipants described their views on alcohol, its' place in their lives, their personal perspectives on reducing their consumption and future aspirations.ConclusionsThe findings provide an insight into participants' views on alcohol, ABI, and the barriers and enablers to change. Participants described a cost benefit analysis, with some conscious consideration of the advantages and disadvantages of reducing intake or abstaining from alcohol. Findings suggest that, whilst hospital admission can act as a catalyst, encouraging individuals to reflect on their alcohol consumption through ABI may consolidate this, turning this reflective moment into action. Sustainability may be enhanced by the presence of a 'significant other' who encourages and experiences benefit. In addition having a purpose or structure with activities linked to employment and/or social and leisure pursuits offers the potential to enhance and sustain reduced alcohol consumption.Trial registrationTrial registration number TRN NCT00982306 September 22nd 2009.

Project description:BackgroundAlcohol misuse in England costs around £7.3 billion (US$12.2 billion) annually from lost productivity and absenteeism. Delivering brief alcohol interventions to employees as part of a health check may be acceptable, particularly with online delivery which can provide privacy for this stigmatised behaviour. Research to support this approach is limited and methodologically weak. The aim was to determine the effectiveness of online screening and personalised feedback on alcohol consumption, delivered in a workplace as part of a health check.Methods and findingsThis two-group online individually randomised controlled trial recruited employees from a UK-based private sector organisation (approx. 100,000 employees). 3,375 employees completed the online health check in the three week recruitment period. Of these, 1,330 (39%) scored five or more on the AUDIT-C (indicating alcohol misuse) and were randomised to receive personalised feedback on their alcohol intake, alongside feedback on other health behaviours (n = 659), or to receive feedback on all health behaviours except alcohol intake (n = 671). Participants were mostly male (75%), with a median age of 48 years and half were in managerial positions (55%). Median Body Mass Index was 26, 12% were smokers, median time undertaking moderate/vigorous physical activity a week was 173 minutes and median fruit and vegetable consumption was three portions a day. Eighty percent (n = 1,066) of participants completed follow-up questionnaires at three months. An intention to treat analysis found no difference between experimental groups for past week drinking (primary outcome) (5.6% increase associated with the intervention (95% CI -4.7% to 16.9%; p = .30)), AUDIT (measure of alcohol-related harm) and health utility (EQ-5D).ConclusionsThere was no evidence to support the use of personalised feedback within an online health check for reducing alcohol consumption among employees in this organisation. Further research is needed on how to engage a larger proportion of employees in screening.Trial registrationInternational Standard Randomised Controlled Trial Number Register ISRCTN50658915.

Project description:AIMS:Unhealthy alcohol use is common among adults, and in particular, Veterans. Routine alcohol screening followed by brief intervention is recommended and considered a prevention priority in primary care settings. While previous studies have found that Veterans enrolled in the Veteran's Health Administration (VA) receive high rates of screening and brief intervention, less than 50% of Veterans receive VA health care. No study has evaluated receipt of these services in a general sample of Veterans. Therefore, in a nationally-representative sample, we examine whether Veteran status was associated with receiving alcohol screening and brief intervention in primary care. METHODS:Using the Centers for Disease Control and Prevention's 2014 Behavioral Risk Factor Surveillance System data, we identified adults who endorsed visiting a doctor for routine checkup at least once in the past two years and responded to an optional module assessing alcohol-related care (N?=?92,206; 14.1% Veterans). Multivariable logistic regression was used to assess the association between Veteran status and screening and brief intervention outcomes. We also evaluate differences in alcohol-related care across Veteran status stratified by gender. Models were adjusted for sociodemographic and clinical characteristics likely to confound the association. RESULTS:Overall, Veterans were more likely than non-Veterans to be screened for alcohol quantity and heavy episodic drinking (ps?<?0.05), and more likely to endorse receiving brief intervention advice about alcohol's harmful effects (p?<?.001). Veteran status predicted an increased likelihood of being screened and receipt of advice about alcohol's harmful effects, but did not predict the likelihood of receiving advice to reduce or abstain from drinking (AOR?=?1.00, 95% C.I. [0.80-1.26]). Analyses stratified by gender indicated a similar pattern of results for males as the overall sample. Results among females indicated Veteran status predicted the likelihood of being asked about heavy episodic drinking (AOR?=?1.47, 95% C.I. [1.09-1.99]) and being offered advice about the harmful effects of alcohol (AOR?=?1.62, 95% C.I. [1.06-2.48]). Female Veterans were not more likely than female non-Veterans to be advised to reduce and/or abstain from drinking. CONCLUSIONS:Screening about any alcohol use was common while report of screening for quantity and heavy episodic drinking occurrence and report of brief intervention were less common. Veterans were more likely than non-Veterans to report receiving recommended care, though rates of advice to reduce or abstain from drinking did not differ across groups. Persistent gaps in delivery of recommended alcohol-related care, especially for particularly vulnerable subpopulations such as women Veterans, suggest a need for quality improvement.
