Over the past two decades, opioid use and overdose have increased substantially. Naloxone, an opioid overdose reversal agent, has been one of many risk mitigation strategies for preventing mortality due to overdose. Most literature describing naloxone utilization has been about populations of illicit drug users and patients in hospitals, primary care, and pharmacies. There is limited information regarding naloxone prescribing and training for opioid users in specialty pain management clinics. Furthermore, there are no known publications concerning patients receiving palliative care services and overdose prevention. Pain and palliative care patients are commonly at risk of opioid overdose. In an interdisciplinary outpatient pain and palliative care clinic, pharmacists implemented naloxone prescribing and education. Eleven patients at increased risk for overdose were prescribed naloxone and educated on overdose risk factors, recognition, and management. Seven patients reported picking up their naloxone prescription from the pharmacy, and none reported using it within two weeks of the initial education. This intervention was deemed successful within the clinic, but small sample size and the pharmacist role may not be replicable within other pain and palliative care settings. It encourages further research of overdose risk and prevention in pain management and palliative care.

BACKGROUND: Buprenorphine is a key medication to treat opioid use disorder (OUD). Since its approval in 2002, buprenorphine access has grown markedly, spurred by major federal and state policy changes. This study characterizes buprenorphine treatment episodes during 2007 to 2018 with respect to payer, provider specialty, and patient demographics. METHODS: In this observational cohort study, IQVIA Real World pharmacy claims data were used to characterize trends in buprenorphine treatment episodes across four time periods: 2007-2009, 2010-2012, 2013-2015, and 2016-2018. RESULTS: In total, we identified more than 4.1 million buprenorphine treatment episodes among 2 540 710 unique individuals. The number of episodes doubled from 652 994 in 2007-2009 to 1 331 980 in 2016-2018. Our findings indicate that the payer landscape changed dramatically, with the most pronounced growth observed for Medicaid (increased from 17% of episodes in 2007-2009 to 37% of episodes in 2016-2018), accompanied by relative declines for both commercial insurance (declined from 35 to 21%) and self-pay (declined from 27 to 11%). Adult primary care providers (PCPs) were the dominant prescribers throughout the study period. The number of episodes among adults older than 55 increased more than 3-fold from 2007-2009 to 2016-2018. In contrast, youth under age 18 experienced an absolute decline in buprenorphine treatment episodes. Buprenorphine episodes increased in length from 2007-2018, particularly among adults over age 45. CONCLUSIONS: Our findings demonstrate that the U.S. experienced clear growth in buprenorphine treatment-particularly for older adults and Medicaid beneficiaries-reflecting some key health policy and implementation success stories. Yet, since the prevalence of OUD and fatal overdose rate have also approximately doubled during this period, the observed growth in buprenorphine treatment did not demonstrably impact the pronounced treatment gap. To date, only a minority of individuals with OUD currently receive treatment, indicating continued need for systemic efforts to equitably improve treatment uptake.

Opioid overdose and Opioid Use Disorder (OUD) statistics underscore an urgent need to significantly expand access to evidence-based OUD treatment. Office Based Opioid Treatment (OBOT) has proven effective for treating OUD. However, limited access to these treatments persists. Recognizing the need for significant investment in clinical, behavioral, and translational research, the Indiana State Department of Health and Indiana University embarked on a research initiative supported by the "Responding to the Addictions Crisis" Grand Challenge Program. This brief presents recommendations based on existing research and our own analyses of medical claims data in Indiana, where opioid misuse is high and treatment access is limited. The recommendations cover target providers, intervention focus, priority regions, and delivery methods.
