Assessing risk for nonmedical opioid use among patients with cancer: Stability of the CAGE-AID questionnaire across clinical care settings

Abstract

Objectives The Cut down, Annoyed, Guilty, and Eye opener- Adapted to Include Drugs (CAGE-AID) questionnaire (CA) is a validated screening tool used to assess risk for nonmedical opioid use (NMOU) in patients receiving opioids for cancer pain. Data on consistencies and variations in responses to the CA between different clinical settings are lacking. We evaluated the frequency and consistency in scoring of the CA among patients seen between the first inpatient consult (T1) and the first outpatient follow-up (T2) visits. Methods A retrospective chart review of 333 consecutive patients seen at both T1 and T2 within 3 months between August 2016 and March 2017 was reviewed. Results Median age was 58 years (range, 18–87 years); 53% were female. CA was completed for 88% of patients at T1 and 94% at T2. Of these, 10% and 13% were CAGE-AID positive, respectively. CA score changed from negative to positive in 4% and from positive to negative in 1% of patients between T1 and T2. Kappa coefficient for agreement of CA between T1 and T2 was 0.74 (95% CI: 0.62–0.86, p = 0.02). Significant of results Completion rate and consistency of patient responses to the CA were high irrespective of clinical setting. Of these patients, 10% and 13% were CA positive which is suggestive of high risk for NMOU. Further studies are needed to evaluate ways to ensure more consistency in the completion of the CA and enhance its utilization in routine clinical practice.
