RESUMO
INTRODUCTION: Misconceptions related to terminology used in the diagnosis and treatment of substance use disorders are common among healthcare providers and may contribute to inappropriate management and education of patients. The objective of this study was to evaluate baseline knowledge of addiction, tolerance, and physical dependence in first-year pharmacy students completing a unit on the neurobiological basis of addiction. METHODS: Students were asked to define the terms addiction, tolerance, and dependence at the beginning of a didactic unit on nervous system pathophysiology and pharmacology. Handwritten responses were transcribed to a spreadsheet and deidentified by sequential assignment to a single numeric identifier. Data were analyzed by three reviewers through open coding and thematic analysis. Descriptive statistics were used to describe the results. RESULTS: One hundred eighty-seven individual student submitted responses were included in the analysis. Many students were unable to provide a substantive definition for the terms physical dependence (32%) and addiction (27%). The definition of tolerance was partially correct in >80% of student responses, though no students provided a complete description. Approximately 5% of students defined physical dependence as addiction, and > 18% incorrectly attributed withdrawal symptoms to addiction. CONCLUSIONS: Significant knowledge gaps or misconceptions regarding terminology related to substance use disorder exists among first-year pharmacy students despite continuing efforts within professional organizations to develop consensus definitions. Developing effective teaching methods to identify and correct misinformation and preconceptions related to care for patients with substance use disorders should continue to be a priority for pharmacy educators.
