OCM community oncology palliative care program: Opioid analgesic utilization.

Abstract

60 Background: Oncology Division of Michigan Health Professionals participates in Oncology Care Model (OCM ). A community oncology program for early and timely involvement of palliative care (PC) was launched in September 2017 to improve cancer pain management. Under-treatment of cancer pain leads to continued patient suffering and impaired quality of life. Appropriate dosing, rotation and frequent assessments are essential for better pain control. This study aims to see the effect of PC on opioid analgesic utilization. Methods: Retrospective claims review was performed with PC patients referred from September 2017 – December 2018 with an opioid class (as defined by CDC) Part D claim (within OCM data). Opioid utilization across agents was measured in morphine-milligram-equivalents (MME). MME per patient per opioid month (PPM) was compared between PC-referred and PC-not referred patients, pre- and post- PC start. Average MME PPM was compared between PC-Engaged and PC declined or unable to reach patients. Within these 2 cohorts, Long-Acting (LA) vs. Short-Acting (SA) opioid utilization was calculated. Results: PC-not referred patients appear to have little monthly variation in opioid dosing. PC-referred patients showed wide variation in opioid dosing before PC. After PC start, opioid dosing stabilized. PC-Engaged patients had more than double MME PPM vs PC declined or unable to reach (2481 MME PPM vs 1198 MME PPM respectively). PC-Engaged patients utilized a higher percentage of LA (43%) whereas PC declined or unable to reach used much less LA (8%). Conclusions: In patients with uncontrolled pain, PC-referral led to decreased variation in opioid dosing and better pain control. Better pain control may be the result of higher utilization of both SA & LA opioids. Patients who do not engage in PC may be at-risk for under-treatment. Study was limited by OCM claims available as of June 2019. Results may be refreshed as more data becomes available.
