Risk of behaviour suggestive of opioid abuse: a protocol for a systematic review of validated assessment tools.

INTRODUCTION: Opioid use patterns of individuals with non-cancer pain are influenced by the behavioural dynamics of the individual in managing and properly following the prescription. The use of assessment tools for measuring the risk of behaviour suggestive of opioid abuse is important for health professionals who provide care to individuals with non-cancer pain. The aim of the proposed review is to analyse the psychometric properties of tools for measuring the risk of behaviour suggestive of opioid abuse in adults with non-cancer pain. METHODS AND ANALYSIS: The review process will be based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. The Consensus-Based Standards for the Selection of Health Measurement Instruments will be used to analyse the assessment tools. Two independent reviewers will perform the literature search and analysis procedures. Searches will be performed on PubMed, Web of Science, Cochrane, Scopus, and Cumulative Index to Nursing and Allied Health Literature databases, and the 'snowball' strategy will be employed. The inclusion criteria will be (1) validation studies, (2) assessment tools designed exclusively for measuring the risk of behaviour suggestive of opioid abuse and (3) assessment tools designed for evaluation of adults with chronic non-cancer pain. The titles and abstracts of the studies retrieved from the databases will be analysed for the preselection of articles, which will be submitted to a full-text analysis to define the final sample. Divergence of opinion between two reviewers will be resolved by consulting a third reviewer. ETHICS AND DISSEMINATION: The review will offer an overview of assessment tools available for measuring the risk of behaviour suggestive of opioid abuse, which is relevant to reducing the risk of deaths due to abusive consumption and for clinical management of adults with chronic non-cancer pain.
