Outcomes of a specialized interdisciplinary approach for cancer patients with aberrant opioid-related behavior: A preliminary report.
212 Background: Data on the development and outcomes of effective interventions to address aberrant opioid-related behavior (AB) in cancer patients is lacking. Our outpatient supportive care clinic developed and implemented a specialized interdisciplinary team approach to manage patients with AB. The purpose of this study was to report clinical outcomes of this novel intervention. Methods: The medical records of 30 consecutive patients with evidence of AB who received the intervention and a random control group of 70 patients without evidence of AB between January 1, 2015 and August 31, 2016 were reviewed. Results: At baseline, pain intensity (p=0.002) and opioid dose (p=0.001) were significantly higher among patients with AB. During the course of the study, the median number of ABs per month significantly decreased from 3 pre-intervention to 0.4 post-intervention (p<0.0001). The median morphine equivalent daily dose decreased from 165mg/day at the first intervention visit to 112mg/day at the last follow up (p=0.018) although pain intensity did not significantly change (p= 0.984). ‘Request for opioid medication refills in the clinic earlier than the expected time’ was the AB with the highest frequency prior to the intervention and the greatest improvement during the study period. Younger age (p<0.0001) and higher ESAS anxiety score (p=0.005) were independent predictors of the presence of AB. Conclusions: The intervention was associated with a reduction in the frequency of AB and opioid utilization among cancer patients receiving chronic opioid therapy. More research is needed to further characterize the clinical effectiveness of this intervention. [Table: see text]
