Treatment Agreement (Contract) • Avoid punitive measures. Continued drug use could suggest To outline patient and provider expectations. a need for treatment intensification. • Stabilizing OUD may help with the management of chronic pain. Urine Drug Testing May be required by provincial regulations. * Most trials report on retention in OAT treatment. While RCT data is limited on patient oriented outcomes, observational data suggests retention in treatment is associated with reduction in mortality and improvement in quality of life. † Eg.

Overview An estimated 1.4 million people in the United States had a substance use disorder related to prescription opioids in 2019.1 However, only a fraction of people with prescription opioid use disorders receive tailored treatment (22 percent in 2019).1 Overdose deaths involving prescription opioids more than quadrupled from 1999 through 2016 followed by significant declines reported in both 2018 and 2019.2,3 Besides overdose, consequences of the opioid crisis include a rising incidence of infants born dependent on opioids because their mothers used these substances during pregnancy4,5 and increased spread of infectious diseases, including HIV and hepatitis C (HCV), as was seen in 2015 in southern Indiana.6 Effective prevention and treatment strategies exist for opioid misuse and use disorder but are highly underutilized across the United States.

  • Acute Pain Management for Inpatients with Opioid Use Disorder
    2.5 HOURS CE Continuing Education Acute Pain Management for Inpatients with Opioid Use Disorder Overcoming misconceptions and prejudices. OVERVIEW: Like most hospital inpatients, those with opioid use disorder (OUD) often experience acute pain during their hospital stay and may require opioid analgesics. Unfortunately, owing to clinicians’ mis- conceptions about opioids and negative attitudes toward patients with OUD, such patients may be inade- quately medicated and thus subjected to unrelieved pain and unnecessary suffering. This article reviews current literature on the topic of acute pain management for inpatients with OUD and dispels common myths about opioids and OUD. Keywords: acute pain, addiction, evidence-based practice, opioid, opioid use disorder, pain, pain manage- ment, substance use disorder nna Barrett, a seasoned RN in the medical– Mr. Jackson notes that Ms. Somers has an order surgical unit of a busy urban hospital, is pro- for morphine 10 mg iv every four hours as needed A viding orientation training to Brian Jackson, for pain relief, in addition to a daily dose of morphine an RN who is new to the unit.

Rodrigueza, and Kaylin A. Klieb,* aAlaska Native Medical Center, Anchorage, AK, USA bUniversity of Colorado, Department of Family Medicine, 1693 N Quentin Street, Aurora, CO, USA ARTICLE INFO ABSTRACT Pharmacotherapy, or medication-assisted treatment (MAT), is a critical component of a comprehensive treatment plan for the pregnant woman with opioid use disorder (OUD). Methadone and buprenorphine are two types of opioid-agonist therapy which prevent withdrawal symptoms and control opioid cravings. Methadone is a long-acting mu-opioid receptor agonist that has been shown to increase retention in treatment programs and attendance at prenatal care while decreasing pregnancy complications. However metha- done can only be administered by treatment facilities when used for OUD. In contrast, buprenorphine is a mixed opioid agonist-antagonist medication that can be prescribed out- patient. The decision to use methadone vs buprenorphine for MAT should be individual- ized based upon local resources and a patient-specific factors. There are limited data on the use of the opioid antagonist naltrexone in pregnancy. National organizations continue to recommend MAT over opioid detoxification during pregnancy due to higher rates of relapse with detoxification. Ó 2019 Elsevier Inc.
