Observational StudyProspective Association of Serum Opioid Levels and Clinical Outcomes in Patients With Cancer Pain Treated With Intrathecal Opioid Therapy.
Opioids remain the mainstay of cancer pain management but are associated with systemic toxicity. In refractory cancer pain, intrathecal therapy (ITT) is associated with improved pain control, reduced systemic side effects, and improved survival. It has been assumed that ITT decreases systemic serum opioid levels and their associated toxicity, but there are limited data to support this assumption. This study hypothesizes that serum opioid levels decrease with ITT. Secondary objectives include comparative measures of pain, bowel function, and other cancer-related symptoms. ⋯ ITT for cancer pain was associated with a marked reduction in serum opioid concentrations, with the majority of patients having undetectable serum levels. Reducing serum opioid concentrations in cancer patients may have implications with respect to restoring bowel function, improving fatigue, and promoting the integrity of antitumor immune function and warrants further study.

Provider Characteristics Associated With Outpatient Opioid Prescribing After Surgery.
To characterize differences in postoperative opioid prescribing across surgical, nonsurgical, and advanced practice providers. ⋯ Advanced practice providers account for 1-in-5 postoperative opioid prescriptions and prescribe larger amounts per prescription relative to surgeons. Engaging all providers involved in postoperative care is necessary to understand prescribing practices, identify barriers to reducing prescribing, and tailor interventions accordingly.

To identify barriers to using state prescription drug monitoring programs (PDMPs) among prescribing physicians and advanced practice registered nurses across a variety of Veterans Health Administration (VA) settings in Oregon. ⋯ Physicians and advanced practice registered nurses across diverse VA settings reported that PDMPs are an important tool and contribute to patient safety. However, issues regarding organizational processes and software design impede optimal use of these resources.

Background: Increasing the total opioid dose is the standard approach for managing uncontrolled cancer pain. Other than simply increasing the opioid dose, palliative care interventions are multidimensional and may improve pain control in the absence of opioid dose increase. Objective: The purpose of this study was to determine the proportion of patients referred to our inpatient palliative care (IPC) team who achieved clinically improved pain (CIP) without opioid dose increase. Design: We reviewed consecutive patients referred to our IPC team. Setting/Subjects: Eligibility criteria included (1) taking opioid medication; (2) having ≥2 consecutive visits with the IPC team; and (3) an Edmonton Symptom Assessment Scale (ESAS) pain score ≥4 at consultation. Measurements: We assessed patient demographics and clinical variables, including cancer type, opioid prescription data (type, route, and oral morphine equivalent daily dose [MEDD]), presence of opioid rotation, psychological consultation, changes in adjuvant medications (e.g., corticosteroids; antiepileptics-gabapentin and pregabalin; benzodiazepines; and neuroleptics), and achievement of CIP. Results: Of the 300 patients enrolled, CIP was achieved in 196 (65%) patients. Of CIP patients, 85 (43%) achieved CIP without an increase in MEDD. CIP without MEDD increase was associated with more adjuvant medication changes (p = 0.003), less opioid rotation (p = 0.005), and lower symptom distress scale of ESAS (p = 0.04). Conclusions: Nearly half of the patients achieved CIP without MEDD increase, suggesting that the multidimensional palliative care intervention is effective in improving pain control in many opioid-tolerant patients without the need to increase the opioid dose.

Chronic pain is a significant public health problem that is associated with several negative health outcomes, including increased health care cost, decreased productivity, and prescription opioid misuse. Although efforts have been made to curb the growing opioid epidemic in the United States, further research is needed to better understand individual difference factors that may be associated with greater pain and opioid misuse. Lower levels of health literacy, defined as the ability to obtain, understand, and use health information to make important decisions regarding health and medical care, has been associated with several chronic illnesses. Yet little work has examined the relationship between health literacy, pain, and opioid misuse among individuals with chronic pain. ⋯ These results suggest that health literacy may contribute to opioid misuse and pain experience among individuals with chronic pain. Interventions targeting health literacy among individuals with chronic illness may help to address the opioid public health crisis.
