IntroductionMillions of persons with chronic pain across North America and Europe use opioids. While the immunosuppressive properties of opioids are associated with risks of infections, these outcomes could be mitigated...

High-risk use of prescription opioids among patients treated for alcohol problems in New York State. A repeated cross-sectional study, 2005–2018

BackgroundPatients with alcohol use disorder (AUD) and high-risk opioid use are at risk of serious complications. The purpose of this study was to estimate the prevalence of and factors associated with high-risk opioid use in patients with an alcohol use problem from 2005 to 2018. MethodsThis repeated cross-sectional study analyzed data from first admissions for alcohol treatment (2005–2018) to the NYS Office of Addiction Services and Supports merged with Medicaid Claims Data. High-risk opioid use was defined as opioid dose ≥50 morphine mg equivalents (MME) per day; opioid prescriptions overlapping ≥7 days; opioids for chronic pain >90 days or opioids for acute pain >7 days. ResultsPatients receiving ≥50 MME increased from 690 to 3226 from 2005 to 2010; then decreased to 2330 in 2018. From 2005–2011, patients with opioid prescriptions overlapping ≥7 days increased from 226 to 1594 then decreased to 892 in 2018. From 2005–2010, opioid use >7 days for acute pain increased from 133 to 970 and plateaued after 2010. From 2005–2018, patients who received opioids >90 days for chronic pain trended from 186 to 1655. White patients, females, age 36–55, patients with chronic and acute pain diagnoses had the highest rates of high-risk use. ConclusionsThe prevalence of high-risk opioid use in patients with alcohol use problems increased from 2005 to 2011, and generally decreased after 2010. However, prevalence of opioids >90 days for chronic pain trended up from 2005 to 2018. High-risk opioid use among patients with AUD emphasizes the need to develop interventional strategies to improve patient care.

Older Adult and Primary Care Practitioner Perspectives on Using, Prescribing, and Deprescribing Opioids for Chronic Pain

Guidelines recommend deprescribing opioids in older adults due to risk of adverse effects, yet little is known about patient-clinician opioid deprescribing conversations. To understand the experiences of older adults and primary care practitioners (PCPs) with using opioids for chronic pain and discussing opioid deprescribing. This qualitative study conducted semistructured individual qualitative interviews with 18 PCPs and 29 adults 65 years or older prescribed opioids between September 15, 2022, and April 26, 2023, at a Boston-based academic medical center. The PCPs were asked about their experiences prescribing and deprescribing opioids to older adults. Patients were asked about their experiences using and discussing opioid medications with PCPs. Shared and conflicting themes between patients and PCPs regarding perceptions of opioid prescribing and barriers to deprescribing. In total, 18 PCPs (12 [67%] younger that 50 years; 10 [56%] female; and 14 [78%] based at an academic practice) and 29 patients (mean [SD] age, 72 [5] years; 19 [66%] female) participated. Participants conveyed that conversations between PCPs and patients on opioid use for chronic pain were typically challenging and that conversations regarding opioid risks and deprescribing were uncommon. Three common themes related to experiences with opioids for chronic pain emerged in both patient and PCP interviews: opioids were used as a last resort, opioids were used to improve function and quality of life, and trust was vital in a clinician-patient relationship. Patients and PCPs expressed conflicting views on risks of opioids, with patients focusing on addiction and PCPs focusing on adverse drug events. Both groups felt deprescribing conversations were often unsuccessful but had conflicting views on barriers to successful conversations. Patients felt deprescribing was often unnecessary unless an adverse event occurred, and many patients had prior negative experiences tapering. The PCPs described gaps in knowledge on how to taper, a lack of clinical access to monitor patients during tapering, and concerns about patient resistance. In this qualitative study, PCPs and older adults receiving long-term opioid therapy viewed the use of opioids as a beneficial last resort for treating chronic pain but expressed dissonant views on the risks associated with opioids, which made deprescribing conversations challenging. Interventions, such as conversation aids, are needed to support collaborative discussion about deprescribing opioids.

Mindfulness training can reduce opioid use among military

Military personnel and veterans who have been taking opioids for chronic pain may experience greater benefits from group therapy that integrates mindfulness techniques than they do from supportive psychotherapy, according to a report published last week in The American Journal of Psychiatry.

Patterns of Opioid Prescriptions in the Veterans Health Administration for Patients With Chronic Low-Back Pain After the Onset of the COVID-19 Pandemic: A Retrospective Cohort Analysis

The COVID-19 pandemic led to severe disruptions in health care and a relaxation of rules surrounding opioid prescribing—changes which led to concerns about increased reliance on opioids for chronic pain and a resurgence of opioid-related harms. Although some studies found that opioid prescriptions increased in the first 6 months of the pandemic, we know little about the longer-term effects of the pandemic on opioid prescriptions. Further, despite the prevalence of pain in veterans, we know little about patterns of opioid prescriptions in the Veterans Health Administration (VA) associated with the pandemic. Using a retrospective cohort of VA patients with chronic low-back pain, we examined the proportion of patients with an opioid prescription and mean morphine milligram equivalents over a 3-year period—1 year prior to and 2 years after the pandemic’s onset. Analyses revealed that both measures fell during the entire observation period. The largest decrease in the odds of filling an opioid prescription occurred in the first quarter of the pandemic, but this downward trend continued throughout the observation period, albeit at a slower pace. Clinically meaningful differences in opioid prescriptions and dose over time did not emerge based on patient race or rurality; however, differences emerged between female and male veterans, with decreases in opioid prescriptions slowing more markedly for women after the pandemic onset. These findings suggest that the pandemic was not associated with short- or long-term increases in opioid prescriptions or doses in the VA. PerspectiveThis article examines opioid prescribing over a 3-year period—1 year prior to and 2 years after the onset of the COVID-19 pandemic—for VA patients with chronic low-back pain. Results indicate that, despite disruptions to health care, opioid prescriptions and doses decreased over the entire observation period.

Risk Factors for Self-Harm Ideation Among Persons Treated With Opioids for Chronic Low Back Pain.

Chronic pain is a significant health concern that adversely affects all aspects of life, including emotional well-being. Opioids are prescribed for the management of refractory, severe chronic pain, although they have been associated with adverse effects, including addiction and overdose. The aim of this study was to examine factors that predict thoughts of self-harm among adults with chronic pain who are prescribed opioids. Seven hundred sixty-five (N=765) persons with opioid-treated chronic lower back pain completed the Current Opioid Misuse Measure (COMM) and other validated questionnaires as part of a larger study. Response to 1 question from the COMM ("How often have you seriously thought about hurting yourself?") was used to assess suicide risk on a 5-point scale (0=never; 4=very often). Participants were categorized into 3 groups according to their responses to the self-harm question: never (N=628; 82.1%), seldom or sometimes (N=74; 9.7%), and often or very often (N=63; 8.2%). Multivariate adjusted odds ratio (aOR) analyses indicated that reports of alcohol or drug overuse within the past month (aOR=1.41,[95% CI 1.11-1.78]), posttraumatic stress (PTSD; aOR=1.24,[1.07 to 1.44]), pain catastrophizing (aOR=1.03,[1.01 to 1.05]), not loving oneself (aOR=0.99,[.98-1.00]) and poor perceived mental health (aOR=0.94,[.92 to 97]) were most associated with thoughts of self-harm. Importantly, the ideation frequency of self-harm was highest among individuals treated with higher daily doses of opioids. These results support the need for continued monitoring of adults treated with opioids for chronic pain, particularly among those on high-dose opioids who present with increased negative affect and concerns of substance misuse.

A qualitative study of chronic pain and opioid use: The impact of restrictive prescribing.

To explore the continuum of pain and addiction for patients with chronic pain (CP) who used opioids during a time of restrictive opioid prescribing in West Virginia. This qualitative descriptive study used a content analysis of semistructured interviews. Themes were identified through a reflective, iterative coding process. Consolidated criteria for reporting qualitative research guidelines were followed. West Virginia. Twenty people who used opioids to treat a CP condition, 10 pharmacists, 10 primary care providers, and 10 specialists. Semistructured interviews. To better understand the impact of restrictive prescribing measures on people who used opioids for CP. Patients initiated opioids for acute, painful conditions and described how long-term use led to physical dependence and, for some, opioid use disorder. Restrictive opioid prescribing laws led to care interruptions and decreased access and availability of prescribed opioid pain medication, driving some patients to seek illicit drugs. Economic considerations influenced drug use as the price of purchasing prescription opioids on the street went up, making heroin a cheaper alternative. Patients who transitioned to buprenorphine/naloxone as a treatment for pain or opioid use disorder viewed it as a positive change and a "life saver." Opioid use for CP is complex and multifaceted. The continuum of pain and opioid use disorder can begin with a prescription for acute pain and continue for the treatment of CP. Patients described how continued opioid use was not to "get high" but for pain control to improve their quality of life, continue to work, and be productive. For those who experience physical dependence on opioids, access to treatment is vital to recovery and pain management. Without individualized managed care, people confronted with a sudden interruption in prescription opioids may turn to illicit drugs to mitigate symptoms of opioid withdrawal and physical dependence.

Improving Access to Care for Patients Taking Opioids for Chronic Pain: Recommendations from a Modified Delphi Panel in Michigan.

About 5-8 million US patients take long-term opioid therapy for chronic pain. In the context of policies and guidelines instituted to reduce inappropriate opioid prescribing, abrupt discontinuations in opioid prescriptions have increased and many primary care clinics will not prescribe opioids for new patients, reducing access to care. This may result in uncontrolled pain and other negative outcomes, such as transition to illicit opioids. The objective of this study was to generate policy, intervention, and research recommendations to improve access to care for these patients. We conducted a RAND/UCLA Modified Delphi, consisting of workshops, background videos and reading materials, and moderated web-based panel discussions held September 2020-January 2021. The panel consisted of 24 individuals from across Michigan, identified via expert nomination and snowball recruitment, including clinical providers, health science researchers, state-level policymakers and regulators, care coordination experts, patient advocates, payor representatives, and community and public health experts. The panel proposed intervention, policy, and research recommendations, scored the feasibility, impact, and importance of each on a 9-point scale, and ranked all recommendations by implementation priority. The panel produced 11 final recommendations across three themes: reimbursement reform, provider education, and reducing racial inequities in care. The 3 reimbursement-focused recommendations were highest ranked (theme average = 4.2/11), including the two top-ranked recommendations: increasing reimbursement for time needed to treat complex chronic pain (ranked #1/11) and bundling payment for multimodal pain care (#2/11). Four provider education recommendations ranked slightly lower (theme average = 6.2/11) and included clarifying the spectrum of opioid dependence and training providers on multimodal treatments. Four recommendations addressed racial inequities (theme average = 7.2/11), such as standardizing pain management protocols to reduce treatment disparities. Panelists indicated reimbursement should incentivize traditionally lower-paying evidence-based pain care, but multiple strategies may be needed to meaningfully expand access.

Microglial inflammation modulates opioid analgesic tolerance.

As we all know, opioids are the drugs of choice for treating severe pain. However, very often, opioid use leads to tolerance, dependence, and hyperalgesia. Therefore, understanding the mechanisms underlying opioid tolerance and designing strategies for increasing the efficacy of opioids in chronic pain are important areas of research. Microglia are brain macrophages that remove debris and dead cells from the brain and participate in immune defense of the central nervous system during an insult or injury. However, recent studies indicate that microglial activation and generation of proinflammatory molecules (e.g., cytokines, nitric oxide, eicosanoids, etc.) in the brain may contribute to opioid tolerance and other side effects of opioid use. In this review, we will summarize the evidence and possible mechanisms by which proinflammatory molecules produced by activated microglia may antagonize the analgesic effect induced by opioids, and thus, lead to opioid tolerance. We will also delineate specific examples of studies that suggest therapeutic targets to counteract the development of tolerance clinically using suppressors of microglial inflammation.

Nurse-Led Telephone Follow-Up Intervention for Titrating and Tapering Opioids in Chronic Pain Patients – A Feasibility Study

Opioids in chronic non-cancer pain are debated, but remain a part of the pain treatment for selected patients. Research is scarce on the relieving and adverse effects of opioids, and how to deliver opioid treatment in this patient group. This study's purpose was to assess the feasibility of a nurse-led telephone follow-up intervention for titrating or tapering opioids, including a pilot study of the intervention outcomes. The feasibility assessment and process evaluation were performed according to the UK Medical Research Council (MRC) framework for evaluating complex interventions. A pilot study of the intervention outcomes was also performed. With a retrospective, descriptive, and longitudinal approach, we analyzed reports from 32 patients who titrated or tapered opioids. Information on demography, sleep satisfaction, health status, pain intensity/bothersomeness, opioid doses, and side effects was derived from the Oslo Pain Registry. Descriptive statistics, t-tests, and chi-square tests were used to analyze registry data. The study findings indicate that the intervention is feasible. Areas of impact were lack of a sound theory basis, unclear allocation criteria, and inconsistent and non-validated measurement tools. Mechanisms of change were interprofessional collaboration, nurses' knowledge and competencies, predictability, and availability. Statistical analyses showed no between-groups differences in demographical-, clinical-, and pain characteristics, except those who titrated opioids were significantly older than patients tapering opioids (P=0.010). All patients reported poor health and side effects at baseline. Those who tapered opioids had a significant reduction in opioid use (P=0.004). Titrating opioids was associated with a significant increase in side effects (P=0.038). Considering the limitations and the strengths of the intervention, the present study indicates that the nurse-led telephone follow-up program is a feasible intervention. With the right adjustments and improvements, the intervention is eligible for a larger efficacy study.

Offering an Alternative to Persons with Chronic Pain: How Access to Cannabis May Provide an Off-Ramp from Undesired Prescription Opioid Use.

Chronic pain (CP) is experienced by as many as 50 million Americans and can negatively impact physical and mental health. Prescribing opioids is the most common approach to address moderate to severe CP though these potent analgesics are associated with a significant number of side effects. One alternative some Americans are turning to for CP management is cannabis. In addition to serving as an alternative, many individuals with CP use cannabis in addition to using prescription opioids. This study examined individuals with CP who enrolled in the state of Illinois' opioid diversion program, the Opioid Alternative Pilot Program (OAPP), which offers individuals aged 21 and older a separate pathway to access medical cannabis if they have or could receive a prescription for opioids as certified by a licensed physician. Cross-sectional survey data were collected from 450 participants. We described participants and compared those who use only cannabis with those who use cannabis and opioids. While 16% of the respondents were cannabis-only users, 84% of the respondents were co-users of opioids and cannabis. Both groups considered opioid use risky (100% cannabis-only, 89% co-users,). The majority (73%) of respondents sought to completely stop or never start using opioids for CP. Cannabis-only users reported lower levels of pain compared to co-users. Co-users (85%) were more likely to have their routine provider as a cannabis certifying physician than cannabis-only users (69%). With increasing clinical evidence, legalization and acceptance, researchers should continue to examine how cannabis may be a viable alternative to reduce the risk of prescription opioid side effects, misuse, or dependence. Our findings also inform health care providers and state policymakers who increasingly are being asked to consider how cannabis may reduce the potential for harmful outcomes among persons with CP who use prescription opioids.

Physician and nurse practitioner perspectives of a modified Routine Opioid Outcome Monitoring (ROOM) Tool.

Introduction The Routine Opioid Outcome Monitoring (ROOM) Tool was developed for use in community pharmacies in Australia. It facilitates pharmacists' screening and brief interventions regarding an individual's opioid use for chronic pain. At our academic teaching hospital, the ROOM Tool was adapted to incorporate a communication tool that includes a pharmacist's assessment and recommendations for primary care providers. This modified ROOM Tool was implemented as part of usual care in our outpatient pharmacies; however, the value to primary care providers is unknown. Aim The aim of this study was to determine primary care provider perspectives on the modified ROOM Tool. Methods Focus groups were conducted with primary care providers from an Academic Family Health Team. The focus group encompassed topics related to the positive and negative aspects of the modified ROOM Tool in supporting the care of patients using opioids for chronic pain. Qualitative content analysis of transcripts was performed to identify themes. Results Three focus groups were conducted with a total of six participants. Four themes emerged: (i) Facilitators to using the tool, (ii) Barriers to using the tool, (iii) Recommendations for improvement, (iv) Impact of the tool on patient care and safety. Discussion The ROOM Tool paired with the communication tool supports collaboration between pharmacists and primary care providers. The communication tool standardises the approach for communicating the pharmacist's assessment and recommendations. Recommendations to refine this modified ROOM Tool may increase its utility to primary care providers and enhance the impact on patient care and safety.

Evaluation of concurrent benzodiazepine and opioid prescribing patterns with a focus on acute muscle spasms indication at hospital discharge

• Concurrent opioids and benzodiazepines increase risk of respiratory depression • Tools to promote risk mitigation with concurrent prescribing • Naloxone recommendations In 2016, the CDC Guidelines for Prescribing Opioids in Chronic Pain recommended avoiding the co-prescribing of opioids and benzodiazepines when possible. This evaluation provides one institution's approach to improve safety for new, acute concurrent opioid and benzodiazepine prescribing. Patients prescribed new, concurrent opioids and benzodiazepines upon discharge within one organization were identified. A chart review for the highest prescribing specialties was completed for a random sample of 100 patients to determine indications for prescribing, safety measures, and post discharge healthcare utilization. Orthopedic surgery, the hospitalist service, neurosurgery, and general surgery had the highest concurrent prescribing rates. The most common indication for benzodiazepine prescribing was muscle spasms, but quantity variability existed across and within all four specialties. Of the subset of patients reviewed, patients were consistently not prescribed naloxone. A prescribing guideline was implemented to provide educational tools, standardized benzodiazepine quantities, and naloxone co-prescribing recommendations for the indication of muscle spasms.

The prevalence of opioid medication use among adults in the United States.

More than one in five American adults experiences chronic pain, and numerous approaches can be used to treat chronic pain. Opioid analgesics are commonly used to treat pain though precise estimates of the prevalence of opi-oid analgesic use vary widely. This study sought to determine the prevalence of opioid use for pain among adults in the United States. We performed a retrospective analysis of the National Health Interview Survey, a national-level house-hold-based annual survey of self-reported health status of US adults, using a chronic pain module introduced in the 2019 edition. We examined overall rates of opioid medication use for pain and correlates of opioid use using survey-weighted analyses. We found 30.8 million adults (95 percent CI: 29.3-32.3 million), or 12.3 percent (11.8-12.8) of the population, had used opioids for pain in the preceding 12 months, while 9.3 million (8.6-10.0 million), or 3.7 percent (3.5-4.0), had used opioids for chronic pain in the preceding 3 months. Individuals reporting pain every day were more likely to have used opi-oids than those experiencing pain less frequently. Individuals who had tried other methods such as physical therapy and self-management programs were more likely to have used opioids. Individuals who used opioids for pain were more likely to report poorly controlled pain, with 38.0 percent (31.5-45.0) reporting their pain management was "not at all effective." Opioid use for chronic pain is common and frequently part of a multimodal and multidisciplinary approach.

Patterns of prescribing in primary care leading to high-dose opioid regimens: a mixed-method study.

There are concerns about continuing increases in the number of patients prescribed long-term opioids and the prescribing of 'strong' opioids for chronic pain. Little is known about patients who are prescribed these long-term, high-dose drugs. To understand patterns of opioid prescribing that lead to long-term, high-dose use. A mixed-method study of the opioid prescription histories of patients using high doses in a North Wales GP practice. All patients on high-dose opioids during the census week were identified. Summary graphs of the prescription histories were prepared. Qualitative analysis was conducted individually by four researchers. A workshop was held to arrive at a consensus about common features and to inform further quantitative analysis. A quarter of high-dose regimens were initiated outside the practice, either in a different primary care practice or in secondary care. The majority of the remaining patients showed a pattern of dose increases to high levels over a short period (median 3.5 months). None showed a pattern of gradual increases over a longer timescale. Most of the patients remained on high doses continuously once a daily dose of ≥120 mg oral morphine equivalent (OME) was reached. These findings suggest that high-dose opioid regimens develop quickly in response to unknown clinical factors. An expected insidious upward drift in dose was not seen. The findings have implications for the prevention of potentially dangerous long-term, high-dose opioid prescribing. A dose of 60 mg OME or more is suggested as a useful 'red flag'.

Development and Testing of a Communication Intervention to Improve Chronic Pain Management in Primary Care: A Pilot Randomized Clinical Trial.

Effective communication skills are essential for optimally managing chronic pain and opioids. This exploratory, sequential mixed methods study tested the effect of a novel framework designed to improve pain-related communication and outcomes. Study 1 developed a novel 5-step framework for helping primary care clinicians discuss chronic pain and opioids with patients. Study 2 pilot tested an intervention for teaching this framework using standardized patient instructors-actors trained to portray patients and provide immediate clinician feedback-deployed during regular clinic hours. Primary care physicians were randomized to receive either the intervention or pain management recommendations from the Centers for Disease Control and Prevention. Primary outcomes were pain-related interference at 2 months and clinician use of targeted communication skills (coded from transcripts of audio-recorded visits); secondary outcomes were pain intensity at 2 months, clinician self-efficacy for communicating about chronic pain, patient experience, and clinician-reported visit difficulty. We enrolled 47 primary care physicians from 2 academic teaching clinics and recorded visits with 48 patients taking opioids for chronic pain who had an appointment scheduled with an enrolled physician. The intervention was not associated with significant changes in primary or secondary outcomes other than clinician self-efficacy, which was significantly greater in the intervention group. This study developed a novel framework and intervention for teaching clinician pain-related communications skills. Although the intervention showed promise, more intensive or multicomponent interventions may be needed to have a significant impact on clinicians' pain-related communication and pain outcomes.

Non-Peptide Opioids Differ in Effects on Mu-Opioid (MOP) and Serotonin 1A (5-HT1A) Receptors Heterodimerization and Cellular Effectors (Ca2+, ERK1/2 and p38) Activation.

The importance of the dynamic interplay between the opioid and the serotonin neuromodulatory systems in chronic pain is well recognized. In this study, we investigated whether these two signalling pathways can be integrated at the single-cell level via direct interactions between the mu-opioid (MOP) and the serotonin 1A (5-HT1A) receptors. Using fluorescence cross-correlation spectroscopy (FCCS), a quantitative method with single-molecule sensitivity, we characterized in live cells MOP and 5-HT1A interactions and the effects of prolonged (18 h) exposure to selected non-peptide opioids: morphine, codeine, oxycodone and fentanyl, on the extent of these interactions. The results indicate that in the plasma membrane, MOP and 5-HT1A receptors form heterodimers that are characterized with an apparent dissociation constant = (440 ± 70) nM). Prolonged exposure to all non-peptide opioids tested facilitated MOP and 5-HT1A heterodimerization and stabilized the heterodimer complexes, albeit to a different extent: = (80 ± 70) nM), = (200 ± 70) nM, = (100 ± 70) nM and = (200 ± 70) nM. The non-peptide opioids differed also in the extent to which they affected the mitogen-activated protein kinases (MAPKs) p38 and the extracellular signal-regulated kinase (Erk1/2), with morphine, codeine and fentanyl activating both pathways, whereas oxycodone activated p38 but not ERK1/2. Acute stimulation with different non-peptide opioids differently affected the intracellular Ca2+ levels and signalling dynamics. Hypothetically, targeting MOP–5-HT1A heterodimer formation could become a new strategy to counteract opioid induced hyperalgesia and help to preserve the analgesic effects of opioids in chronic pain.
