Continuous morphine infusions (CMIs) treat pain and dyspnea at the end of life (EOL). CMIs may be initiated at an empiric rate and/or are rapidly escalated without proper titration. ⋯ Hospitalized patients at EOL had a much higher 24-hour IV morphine equivalents and CMI rates at time of death compared to CMI initiation. Variability was observed in the number of CMI rate adjustments and the number of bolus doses administered.

With escalating opioid prescribing come individual and public health harms. To inform quality improvement measures, understanding of opioid prescribing is essential. We aimed to establish consultation-level prevalence and associations of opioid prescribing. ⋯ Most opioids were prescribed as maintenance therapy for non-cancer pain. Demographic associations with opioid analgesic prescribing resemble those presenting for opioid dependency treatment. Our findings should inform measures by regulators and medical educators supporting multimodal pain management.

The purpose of this study was to determine baseline adherence to key recommendations from the 2010 VA/DOD Clinical Practice Guideline for Opioid Therapy for Chronic Pain at Veterans Health Administration (VA) facilities. We hoped to understand practice patterns at the time of guideline release to guide quality improvement and implementation efforts. ⋯ In 2010, guideline-recommended practices for opioid prescribing were variably used across VA health care systems. Efforts to disseminate practices used at high-performing sites, and increase consistency of use of recommended practices across patients and facilities should be considered to improve pain management and reduce adverse events.

Orexin type 1 receptor antagonism in rat locus coeruleus prevents the analgesic effect of intra-LC met-enkephalin microinjection.
Long-term administration of opiates leads to development of tolerance to analgesic effects. This in turn compromise clinical use of these drugs for pain management. Although extensive studies have been conducted, the involved cellular mechanisms are still poorly understood. ⋯ Results indicate that intra-LC microinjection of ME (5μg/100nL) results in development of analgesic tolerance in 3days. Also, OX1R antagonism in LC nucleus significantly prevents the analgesic effect of intra-LC met-enkephalin microinjection. It appears that the analgesic effect of ME in LC neurons is mediated by orexinergic system.

To determine if an opioid prescribing guideline poster, meant to be posted in an emergency department (ED) triage area, would deter patients with chronic pain from seeking care. ⋯ The vast majority of patients with chronic pain in this cohort believes that a pain guideline poster is reasonable and should be posted in the ED. However, a small percentage of patients reported that they would feel intimidated by such a poster and that it would prevent them from staying to get care, a result meant to inform hospitals and policy-makers deciding if such posters should be displayed.
