The provision of preventive care for modifiable health risk behaviours by clinicians within substance use treatment settings: A systematic review

Abstract

People who use substances have a high prevalence of other modifiable health risk behaviours such as tobacco smoking which contribute to an increased mortality and morbidity. Preventive care can reduce the prevalence of such behaviours and is recommended by clinical practice guidelines. This review describes the prevalence of preventive care delivery by substance use treatment healthcare providers and examines differences by treatment setting. Five databases were searched for studies published between 2005 and 2017. Eligible studies reported levels of preventive care (assessment, brief advice and/or referral/follow-up) in substance use treatment services for tobacco smoking, nutrition or physical activity. Two reviewers independently conducted article screening, data extraction and methodological quality assessment. Sixteen studies were included and all except one investigated care provision for tobacco smoking only. Four studies reported care levels as a proportion and 12 studies reported care as a score-based mean. Client-reported receipt of smoking cessation care ranged from: 79-90% for assessment; 15-79% for brief advice; 0-30% for referral/follow-up. Meta-regression analyses of 12 studies found clinician-reported preventative care for tobacco smoking was more frequently reported in studies assessing care occurring across multiple substance use treatment settings, compared to studies reporting provision in inpatient only. This review indicated that, compared to smoking cessation care, little is known about the level of preventive care for nutrition or physical activity. Overall, the delivery of smoking cessation care reported was sub-optimal. High levels of assessment relative to brief advice and low levels of referral to ongoing assistance were indicated.
