Alcohol screening and brief intervention in workplace settings and social services: a comparison of literature
Employee alcohol and other drug use can negatively impact the workplace, resulting in absenteeism, reduced productivity, high turnover, and worksite safety issues. As the workplace can influence employee substance use through environmental and cultural factors, it also presents a key opportunity to deliver interventions, particularly to employees who may not otherwise seek help. This is a systematic review of workplace-based interventions for the prevention and treatment of problematic substance use. Five databases were searched for efficacy, effectiveness and/or cost-effectiveness studies and reviews published since 2010 that measured use of psychoactive substances (i.e., alcohol, cannabis, hallucinogens, inhalants, opioids, sedatives, hypnotics, anxiolytics, and stimulants) as a primary or secondary outcome, in employees aged over 18. Thirty-nine articles were identified, 28 describing primary research and 11 reviews, most of which focused solely on alcohol use. Heterogeneity between studies with respect to intervention and evaluation design limited the degree to which findings could be synthesized, however, there is some promising evidence for workplace-based universal health promotion interventions, targeted brief interventions, and universal substance use screening. The few studies that examined implementation in the workplace revealed specific barriers including lack of engagement with e-health interventions, heavy use and reluctance to seek help amongst male employees, and confidentiality concerns. Tailoring interventions to each workplace, and ease of implementation and employee engagement emerged as facilitators. Further high-quality research is needed to examine the effectiveness of workplace substance use testing, Employee Assistance Programs, and strategies targeting the use of substances other than alcohol in the workplace.



Social Services
Social services are often the first point of contact for individuals and families experiencing the consequences of alcohol-related harm, including those who may not access health care. This includes child protection, youth services, migrant support, domestic violence services and community-based rehabilitation.
Integrating screening and brief interventions into social care allows for the early identification of alcohol-related risks and provides opportunities to offer timely, person-centred support. Social workers, NGOs and community practitioners are well placed to deliver brief conversations about alcohol use and to connect individuals and families with further support.
When embedded in routine social service practice, these interventions can help prevent long-term harm and improve outcomes for individuals, families and communities, while strengthening collaboration between social and health services.
