A bibliometric review of drug and alcohol research focused on Indigenous peoples of Australia, New Zealand, Canada and the United States

Issues. Indigenous peoples of Australia, New Zealand, Canada and the United States experience a disproportionately high burden of harms from substance misuse. Research is therefore required to improve our understanding of substance use in Indigenous populations and provide evidence on strategies effective for reducing harmful use. Approach. A search of 13 electronic databases for peer-reviewed articles published between 1993 and 2014 focusing on substance use and Indigenous peoples of Australia, New Zealand, Canada and the United States. Relevant abstracts were classified as data or non-data based research. Data-based studies were further classified as measurement, descriptive or intervention and their trends examined by country and drug type. Intervention studies were classified by type and their evaluation designs classified using the Cochrane Effective Practice and Organisation of Care (EPOC) data collection checklist. Key Findings. There was a statistically significant increase from 1993 to 2014 in the percentage of total publications that were data-based (P < 0.001). Overall, data-based publications were mostly descriptive for all countries (84-93%) and drug types (74-95%). There were fewer measurement (0-4%) and intervention (0-14%) publications for all countries and the percentage of these did not change significantly over time. Forty-two percent of intervention studies employed an EPOC evaluation design. Implications. Strategies to increase the frequency and quality of measurement and intervention research in the Indigenous drug and alcohol field are required. Conclusion. The dominance of descriptive research in the Indigenous drug and alcohol field is less than optimal for generating evidence to inform Indigenous drug and alcohol policy and programs.
