Community based interventions for problematic substance use in later life: A systematic review of evaluated studies and their outcomes


Problematic substance use (PSU) in later life is a growing global problem of significant concern in tandem with a rapidly ageing global population. Prevention and interventions specifically designed for older people are not common, and those designed for mixed-age groups may fail to address the unique and sometimes complex needs of ageing communities. We report findings from a systematic review of the empirical evidence from studies which formally evaluated interventions used with older people and reported their outcomes. Nineteen studies were included, of which thirteen focused solely on alcohol-related problems. Most interventions (eight) utilised different types of screening, brief advice and education. The remaining drew on behavioural, narrative and integrated or multi-disciplinary approaches which aimed to meet people’s needs holistically. Quality assessment of study design helped to review evaluation practice. Recommendations are for more sustainable and well-designed intervention strategies for PSU in later life, which purposefully align with other areas of health and wellbeing and are delivered in locations where older people normally seek, or receive, help. Further scope for engagement with people’s own perspectives on their needs, and help-seeking, and for economic evaluation of the outcome of interventions could establish the value of investing in targeted services to this underserved population.
