Abstract
BACKGROUND Emergency department (ED) boarding of psychiatric patients is a national issue that continues to worsen at a disturbing rate. Implementing strategies in the ED to provide continuous care for patients can help secure patient safety. OBJECTIVE The objective of this review is to discuss the boarding of psychiatric patients and its implications. It will focus on executing best clinical practices in managing boarding psychiatric patients in the ED. It will not focus on the treatment of substance use disorders. DISCUSSION This article will address the pearls for management plans that can be implemented in the ED, alongside discussing pregnant and elderly patients. Risk factors, complications, and treatments for boarding psychiatric patients are discussed. CONCLUSIONS Patients with psychiatric disorders boarding in the ED need careful consideration of management plans to mitigate patient safety events.

Abstract
INTRODUCTION Medications for opioid use disorder (MOUD) include opioid agonist therapies (OAT) (buprenorphine and methadone), and opioid antagonists (extended-release naltrexone). All forms of MOUD improve opioid use disorder (OUD) and HIV outcomes. However, the integration of services for HIV and OUD remains inadequate. Persistent barriers to accessing MOUD underscore the immediate necessity of addressing pharmacoequity in the treatment of OUD in persons with HIV (PWH). AREAS COVERED In this review article, we specifically focus on OAT among PWH, as it is the most commonly utilized form of MOUD. Specifically, we delineate the intersection of HIV and OUD services, emphasizing their integration into the United States Ending the HIV Epidemic (EHE) plan by offering comprehensive screening, testing, and treatment for both HIV and OUD. We identify potential drug interactions of OAT with antiretroviral therapy (ART), address disparities in OAT access, and present the practical benefits of long-acting formulations of buprenorphine, ART, and pre-exposure prophylaxis for improving HIV prevention and treatment and OUD management. EXPERT OPINION Optimizing OUD outcomes in PWH necessitates careful attention to diagnosing OUD, initiating OUD treatment, and ensuring medication retention. Innovative approaches to healthcare delivery, such as mobile pharmacies, can integrate both OUD and HIV and reach underserved populations.

Abstract
BACKGROUND Injection Drug use is associated with increased HIV risk behaviour that may result in the transmission of HIV and poor access to HIV prevention and treatment. In 2020, Uganda introduced the 'medication for opioid use disorder (MOUD) treatment' for People who inject drugs (PWID). We analysed the 12-month retention and associated factors among PWID enrolled on MOUD treatment in Kampala, Uganda. METHODS We conducted a retrospective analysis of 343 PWID with OUD who completed 14 days of methadone induction from September 2020 to July 2022. Retention was defined as the number of individuals still in the programme divided by the total number enrolled, computed at 3-, 6-, 9-, and 12 months using lifetable and Kaplan-Meier survival analyses. Cox proportional regression analyses were conducted to assess factors associated with retention in the programme in the first 12 months. RESULTS Overall, 243 (71%) of 343 participants stabilized at a methadone dose of 60 mg or more. The majority of participants were males (n = 284, 82.8%), and the median (interquartile range, IQR) age was 31 (26-38) years. Most participants (n = 276, 80.5%) lived 5 km or more away from the MOUD clinic. Thirty (8.8%) were HIV-positive, 52 (15.7%) had a major mental illness and 96 (27.9%) had a history of taking alcohol three months before enrollment. The cumulative retention significantly declined from 83.4% (95%CI = 79.0-87.0) at 3months to 71.9% (95%CI = 67.2-76.6) at 6months, 64% 95%CI = 58.7-68.9) at 9months, and 55.2%; 95% CI (49.8-60.3% at 12months. The 12-month retention was significantly higher for participants on methadone doses of 60 mg or more (adj.HR = 2.1, 95%CI = 1.41-3.22), while participants resident within 5 km of the MOUD clinic were 4.9 times more likely to be retained at 12 months, compared to those residing 5 km or more, (adj. HR = 4.81, 95%CI = 1.54-15). Other factors, including predisposing, need, and enabling factors, were not associated with retention. CONCLUSION Our study demonstrates acceptable 12-month retention rates for people who inject drugs, comparable to previous studies done in both developing and developed countries. Sustaining and improving retention may require enhanced scaling up of MOUD dose to an optimal level in the first 14 days and reducing the distance between participant locale and MOUD clinics.

Drug Alcohol Depend 2024; 258:111136. [PMID: 38518662 DOI: 10.1016/j.drugalcdep.2024.111136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Revised: 02/13/2024] [Accepted: 02/17/2024] [Indexed: 03/24/2024]
Abstract
OBJECTIVE We sought to answer the question of how adolescents (ages 12-17 years old) with opioid-related presentations are currently managed in the ED. The two main outcomes were the proportion of visits where naloxone and buprenorphine were both used and prescribed, and the rate of revisits to the emergency department in the six months following ED presentation. METHODS This was a multi-center retrospective cross-sectional study. We studied patients presenting to the ED who were 12-17 years old with an opioid-related presentation. RESULTS Two-hundred and thirty-one patients were identified out of 571 encounters screened. Of these presentations, 77/231 (33%) were girls and 154/231 (67%) were boys. The majority of patients were Latino (64%; n=147); 26% were white (n=59), 6% were middle eastern or Arab (14), and 4% were black (10). Incidence of opioid use disorder per 100,000 presentations increased by 2800% from 2014 to 2022 (21/100,000 +/- 10 [2014] to 600/100,000 +/- 50 [2022]). A plurality of cases was related to opioid withdrawal (42%; 97). On discharge from the ED, 29% of patients received naloxone. For patients in withdrawal, 4% received a prescription for buprenorphine. Twenty-nine percent of patients had a return to the ED in the six months following initial visit. CONCLUSIONS Adolescent opioid-related presentations to the ED are rapidly increasing. Increasing ED presentations, compounded by a high 6-month revisit rate, pose a management challenge amid limited outpatient resources for this population. Opioid agonist therapy and naloxone are not routinely provided. Increasing the use of both are two ways to improve the quality of care for this population.

Abstract
BACKGROUND In adults with chronic pain, mild-to-moderate withdrawal symptoms during medically directed opioid tapering in the outpatient setting may not be accompanied by hypertension or tachycardia. This clinical scenario could limit the use of lofexidine at dosages reported in clinical trials of opioid withdrawal precipitated by abrupt opioid discontinuation. Thus, the primary aim of this prospective case series is to describe the use of low dose lofexidine for opioid withdrawal in patients with chronic pain undergoing medically directed opioid tapering in an outpatient setting. METHODS Six patients (white 5, Latino 1) admitted to an outpatient interdisciplinary pain rehabilitation program met inclusion and exclusion criteria. Patients self-selected to undergo medically directed opioid tapering, and the medication the patients were prescribed upon admission was used in the taper schedule. Upon initiation of the opioid taper, patients received 0.18 mg of lofexidine every 6 hours. RESULTS Five of the six patients were women, and the median morphine milligram equivalents at baseline were 36.9. The median taper duration was 15 days, and the median duration of lofexidine administration was 14 days. Withdrawal scores were mild throughout the taper in four patients, and two patients with fibromyalgia experienced single episodes of moderately severe withdrawal symptoms at the median morphine milligram equivalent midpoint of the taper. No hypotension or sustained bradycardia were observed, and no adverse effects related to lofexidine were reported. CONCLUSION The observations from this prospective case series suggest that low-dose lofexidine may be a feasible adjunct medication to attenuate withdrawal symptoms in adults with chronic pain undergoing outpatient opioid tapering.

Abstract
The current review describes updated information on the evidence-based assessment of substance use disorder. We offer an overview of the state of the science for substance-related assessment targets, instruments (screening, diagnosis, outcome and treatment monitoring, and psychosocial functioning and wellbeing) and processes (relational and technical) as well as recommendations for each of these three components. We encourage assessors to reflect on their own biases, beliefs, and values, including how those relate to people that use substances, and to view the individual as a whole person. It is important to consider a person's profile of symptoms and functioning inclusive of strengths, comorbidities, and social and cultural determinants. Collaborating with the patient to select the assessment target that best fits their goals and integration of assessment information in a holistic manner is critical. We conclude by providing recommendations for assessment targets, instruments, and processes as well as recommendations for comprehensive substance use disorder assessment, and describe future directions for research.

Abstract
PURPOSE Sex differences may exist in opioid use disorder (OUD) treatment. This study examined the treatment effects of buprenorphine/naloxone (BUP/NX) and methadone (MET) on the Clinical Opiate Withdrawal Scale (COWS) score in individuals with OUD and tested whether the associations differ by sex. METHOD We performed a secondary analysis of the data from the National Drug Abuse Treatment Clinical Trials Network (CTN) protocol-0027. A total of 1269 participants (861 males and 408 females) being aged 18 or older with OUD were randomly assigned to receive BUP/NX (n = 740) or MET (n = 529). The paired t test was initially used to compare the COWS scores between pre-dose and post-dose for BUP/NX and MET treatments, separately. The linear mixed model was used to examine the changes in COWS score adjusted for baseline demographic, substance use, and mental health disorders. The interaction of sex and treatment was detected and stratified analysis by sex was conducted. RESULTS The paired t test showed that both BUP/NX and MET treatments significantly reduced the COWS scores (p values <0.0001). BUP/NX revealed higher COWS scores than MET (p = 0.0008) and females demonstrated significantly higher COWS scores than males (p = 0.0169). Stratified by sex, BUP/NX compared with MET revealed higher COWS scores only in males (p = 0.0043), whereas baseline amphetamines use disorder and major depressive disorder were significantly associated with COWS scores in females (p = 0.0158 and 0.0422, respectively). CONCLUSIONS Both BUP/NX and MET are effective in decreasing opioid withdrawal symptoms via COWS scores, however, treatment plans for OUD by clinical providers should consider sex differences.

Abstract
Concurrent alcohol and opioid withdrawal syndrome is a common and challenging clinical scenario with little published evidence or guidance to inform pharmacotherapy strategies. Concurrent use of benzodiazepines and opioid agonists, which are considered first-line agents for management of each withdrawal syndrome independently, is controversial and often avoided in clinical practice. Strategies to provide effective, simultaneous medication treatment of alcohol and opioid withdrawal while optimizing patient safety are demonstrated through 3 patient cases.

Abstract
Tramadol and venlafaxine share similar pharmacological characteristics that may allow for overlapping therapeutic indications for them. The objective of this study was to compare the efficacy of venlafaxine and naltrexone in the treatment of tramadol abuse. This comparative trial included 95 patients with tramadol abuse who were detoxified for 2 weeks. Twenty-eight participants underwent the maintenance phase, while the remaining participants (n = 67) dropped out. The patients were randomized to use 50 mg/day of naltrexone or 225 mg/day of venlafaxine for 8 weeks. All participants were interviewed using SCID-I (DSM-IV-TR) criteria for diagnosing substance use and other psychiatric disorders. The proportion of relapsed patients was comparable between the naltrexone and venlafaxine groups (29.4% vs. 30.4%, P = 0.9). However, participants in the venlafaxine group stayed in treatment longer than participants in the naltrexone group, and the difference was significant (22.9 ± 7.89 days vs. 16.9 ± 3.4 days, P = 0.01). Only psychiatric comorbidity was found to be significantly associated with retention in treatment (80% vs. 22%, P = 0.005). Venlafaxine is as effective as naltrexone in preventing relapse in patients with tramadol abuse. Venlafaxine was more effective than naltrexone in treatment retention.

Abstract
Buprenorphine inductions traditionally require an opioid-free period due to the risk of precipitated opioid withdrawal. Hospitalized patients with opioid use disorder and concurrent acute pain may be eligible for buprenorphine therapy. However, effective buprenorphine induction strategies in this patient population have not been well established. Investigators sought to review the completion of a low dose induction protocol that does not require an opioid-free period prior to buprenorphine initiation. Hospitalized patients who completed a 7-day low dose induction protocol via buprenorphine transdermal patches October 2021 - March 2022 were examined via retrospective chart review (N = 7). All seven patients completed the induction and were discharged on sublingual buprenorphine. Low dose transdermal buprenorphine provides a reasonable strategy for hospitalized patients on full agonist opioid therapy or those who have failed conventional buprenorphine induction strategies. Reducing barriers such as opioid abstinence is key to combating opioid use disorder.

Abstract
Difelikefalin is a selective kappa opioid receptor agonist approved for treating moderate-to-severe pruritus in adults undergoing hemodialysis (HD). Difelikefalin is not a controlled substance under the Controlled Substances Act. This study assessed the potential for developing physical dependence on difelikefalin in patients undergoing HD. Eligible patients received open-label difelikefalin after each dialysis session for 3 weeks before entering a 2-week double-blind phase, when they were randomized to either continue difelikefalin or to switch to receiving placebo. Signs of physical withdrawal were assessed using the Clinical Opiate Withdrawal Scale (COWS), several patient-reported scales, and physiological measures. The primary end point was the between-group difference in mean maximum COWS total scores during the double-blind phase; the mean difference (placebo - difelikefalin) was compared against a predefined noninferiority limit (+4). Thirty-five patients (57.1% male; 91.4% Black or African American; median [range] age 58 [28-77] years) were included, of which 30 were randomized (placebo, n = 14; difelikefalin, n = 16). The least squares mean difference in maximum COWS total scores was 0.52 (95% confidence interval [CI]: -0.56, 1.59). The upper CI limit (1.59) was below +4, indicating that patients who discontinued difelikefalin (placebo group) had similar withdrawal scores to patients who continued difelikefalin. Additional assessments supported the COWS results, showing no meaningful differences between groups in physiological measures or in patient-reported measures of sleep or physical withdrawal. These results demonstrate that abruptly discontinuing chronic difelikefalin treatment in patients undergoing HD does not produce signs or symptoms of physical withdrawal.

Surmounting Withdrawal to Initiate Fast Treatment with Naltrexone (SWIFT): A stepped wedge hybrid type 1 effectiveness-implementation study. Contemp Clin Trials 2023; 128:107148. [PMID: 36931426 PMCID: PMC10895892 DOI: 10.1016/j.cct.2023.107148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 03/08/2023] [Accepted: 03/09/2023] [Indexed: 03/17/2023]
Abstract
BACKGROUND Extended-release injectable naltrexone (XR-NTX) is an effective treatment for opioid use disorder (OUD), but initiation remains a barrier to implementation. Standard practice requires a 10- to 15-day inpatient admission prior to XR-NTX initiation and involves a methadone or buprenorphine taper followed by a 7- to 10-day washout, as recommended in the Prescribing Information for XR-NTX. A 5- to 7-day rapid induction approach was developed that utilizes low-dose oral naltrexone and non-opioid medications. METHODS The CTN-0097 Surmounting Withdrawal to Initiate Fast Treatment with Naltrexone (SWIFT) study was a hybrid type I effectiveness-implementation trial that compared the effectiveness of the standard procedure (SP) to the rapid procedure (RP) for XR-NTX initiation across six community inpatient addiction treatment units, and evaluated the implementation process. Sites were randomized to RP every 14 weeks in an optimized stepped wedge design. Participants (target recruitment = 450) received the procedure (SP or RP) that the site was implementing at time of admission. The hypothesis was RP will be non-inferior to SP on proportion of inpatients who receive XR-NTX, with a shorter admission time for RP. Superiority testing of RP was planned if the null hypothesis of inferiority of RP to SP was rejected. DISCUSSION If RP for XR-NTX initiation is shown to be effective, the shorter inpatient stay could make XR-NTX more feasible and have an important public health impact expanding access to OUD pharmacotherapy. Further, a better understanding of facilitators and barriers to RP implementation can help with future translatability and uptake to other community programs.

Abstract
PURPOSE Using data from a randomized controlled trial for treatment of prescription-type opioid use disorder in Canada, this study examines sensitivity to change in three preference-based instruments [EQ-5D-3L, EQ-5D-5L, and the Health Utilities Index Mark 3 (HUI3)] and explores an oft-overlooked consideration when working with contemporaneous responses for similar questions-data quality. METHODS Analyses focused on the relative abilities of three instruments to capture change in health status. Distributional methods were used to categorize individuals as 'improved' or 'not improved' for eight anchors (seven clinical, one generic). Sensitivity to change was assessed using area under the ROC (receiver operating characteristics) curve (AUC) analysis and comparisons of mean change scores for three time periods. A 'strict' data quality criteria, defined a priori, was applied. Analyses were replicated using 'soft' and 'no' criteria. RESULTS Data from 160 individuals were used in the analysis; 30% had at least one data quality violation at baseline. Despite mean index scores being significantly lower for the HUI3 compared with EQ-5D instruments at each time point, the magnitudes of change scores were similar. No instrument demonstrated superior sensitivity to change. While six of the 10 highest AUC estimates were for the HUI3, 'moderate' classifications of discriminative ability were identified in 12 (of 22) analyses for each EQ-5D instrument, compared with eight for the HUI3. CONCLUSION Negligible differences were observed between the EQ-5D-3L, EQ-5D-5L, and HUI3 regarding the ability to measure change. The prevalence of data quality violations-which differed by ethnicity-requires further investigation.

Abstract
Introduction Working memory describes the ability to maintain and manipulate information held in mind, and it is a fundamental aspect of executive function. Within drug addiction, impairments of executive control over behavior are thought to lead to poor decision making and risky behaviors. Previous research has demonstrated working memory (WM) and executive function difficulties in opioid-dependent individuals, but the neural underpinnings of such impairments in this population are not well understood. Methods This study used functional magnetic resonance imaging to examine the neural mechanisms involved in WM in 13 opioid-dependent, methadone-maintained participants (OP) and 13 matched, healthy controls (HC). A Sternberg item-recognition task was administered with three conditions: (1) a "verbal" condition in which participants determined whether any six visually presented target letters matched a probe item that was presented 4-6 s later, (2) a "non-verbal" condition in which participants were presented with a Chinese character and, following a 4-6 s delay, determined whether the character matched the probe item, and (3) a "control" condition in which participants were presented with three horizontal lines and following the same delay, determined whether the lines matched a probe item (always the same three lines). Functional magnetic resonance imaging (fMRI) contrasts focused on the delay (or "maintenance") phase for verbal and non-verbal conditions relative to the control condition. Results Accuracy on the WM task did not differ between groups, but the OP group was significantly slower to respond. The fMRI imaging results indicated differences in brain activity between the OP and HC groups. fMRI-guided regions of interest correlated with age of first alcohol and THC use, suggesting that early substance use, in addition to years of opioid-abuse, may have played a role in the OP group's WM performance. Discussion A deeper understanding of these neural differences between opioid-dependent individuals and their healthy control counterparts helps shed light on fundamental ways in which substance use impacts the brain and cognition, potentially opening up novel avenues for therapeutic targets to treat substance use disorder.

Abstract
STUDY OBJECTIVES The development of restless legs syndrome (RLS) has been rarely reported during and following opioid withdrawal. We aimed to determine the presence and severity of RLS symptoms during and after supervised opioid tapering. METHODS Ninety-seven adults enrolled in the Mayo Clinic Pain Rehabilitation Center who underwent supervised prescription opioid tapering were prospectively recruited. RLS presence and severity was assessed with the Cambridge-Hopkins Questionnaire 13 and International Restless Legs Syndrome Study Group Rating Severity Scale at admission, midpoint, and dismissal from the program as well as 2 weeks, 4 weeks, and 3 months after completion. Frequency and severity of RLS symptoms were compared between admission and each time point. RESULTS Average age of the cohort was 52.6 ± 13.3 years with a morphine milligram equivalent dose for the cohort of 45.6 ± 48.3 mg. Frequency of RLS symptoms increased from 28% at admission to peak frequency of 41% at 2 weeks following discharge from the Mayo Pain Rehabilitation Clinic (P = .01), returning to near baseline frequency 3 months after opioid discontinuation. International Restless Legs Syndrome Study Group Rating Severity Scale increased from baseline and then remained relatively stable at each time point following admission. Thirty-five (36.1%) participants developed de novo symptoms of RLS during their opioid taper, with those being exposed to higher morphine milligram equivalent doses having higher risk of developing RLS. CONCLUSIONS Moderately severe symptoms of RLS, as assessed by survey, occur commonly in individuals undergoing opioid tapering, particularly if exposed to higher doses. In many cases, symptoms appear to be self-limited, although a minority develop persistent symptoms. Our results may have implications for successful opioid tapering, but future confirmatory studies with structured clinician interview are needed to establish that these symptoms truly represent restless legs syndrome given the potential for RLS-mimicking symptoms in individuals with chronic pain syndromes.

Abstract
BACKGROUND and purpose: The seeds of Sophora alopecuroides var. alopecuroides have attenuated the acute opium withdrawal syndrome in humans. Therefore, the efficacy and safety of a standardized extract of the plant for the treatment of acute heroin withdrawal syndrome was evaluated in abstinent heroin addicts. MATERIALS AND METHODS The patients were randomized to take three 400 mg extract capsules (N = 50) or placebo (N = 50) once per day orally for eight days. The severity of withdrawal syndrome was assessed by the clinical opiate withdrawal scale (COWS) as the primary outcome measure at the baseline and on the days 3 and 8. The hepatic and renal functions and complete blood count were the secondary outcome measures tested at the baseline and end of the study. RESULTS The COWS score decreased in both groups after eight days, but the decrease was significantly higher in the experimental group (p < 0.001); the effect size of the decrease was 2.64. The groups had significant differences in the COWS scores on the days 3 and 8 (p < 0.001 for both). The extract had no significant effect on the other parameters. No side effect was noted. CONCLUSION The extract seems to alleviate acute heroin withdrawal syndrome safely.

Abstract
BACKGROUND Novel strategies are needed to curb the opioid overdose epidemic. Smart home sensors have been successfully deployed as digital biomarkers to monitor health conditions, yet they have not been used to assess symptoms important to opioid use and overdose risks. AIM This study piloted smart home sensors and investigated their ability to accurately detect clinically pertinent symptoms indicative of opioid withdrawal or respiratory depression in adults prescribed methadone. METHODS Participants (n = 4; 3 completed) were adults with opioid use disorder exhibiting moderate levels of pain intensity, withdrawal symptoms, and sleep disturbance. Participants were invited to two 8-hour nighttime sleep opportunities to be recorded in a sleep research laboratory, using observed polysomnography and ambient smart home sensors attached to lab bedroom walls. Measures of feasibility included completeness of data captured. Accuracy was determined by comparing polysomnographic data of sleep/wake and respiratory status assessments with time and event sensor data. RESULTS Smart home sensors captured overnight data on 48 out of 64 hours (75% completeness). Sensors detected sleep/wake patterns in alignment with observed sleep episodes captured by polysomnography 89.4% of the time. Apnea events (n = 118) were only detected with smart home sensors in two episodes where oxygen desaturations were less severe (>80%). CONCLUSIONS Smart home technology could serve as a less invasive substitute for biologic monitoring for adults with pain, sleep disturbances, and opioid withdrawal symptoms. Supplemental sensors should be added to detect apnea events. Such innovations could provide a step forward in assessing overnight symptoms important to populations taking opioids.

Abstract
Background: For patients with opioid use disorder, buprenorphine extended-release injection (BUP-XR) achieves sustained therapeutic plasma concentrations, controls craving and withdrawal symptoms, and improves patient outcomes. Given retention challenges during transmucosal buprenorphine (BUP-TM) induction, assessing methods to quickly achieve sustained buprenorphine concentrations is important.Objectives: This open-label, single-group, single-center pilot study (NCT03993392) evaluated safety and tolerability of initiating BUP-XR following a single BUP-TM 4 mg dose.Methods: Eligible participants abstained from short and long-acting opioids for 6 and 24 hours, respectively. If the Clinical Opiate Withdrawal Scale (COWS) was ≥8, BUP-TM 4 mg was administered. Participants not exhibiting hypersensitivity, precipitated opioid withdrawal (POW), or sedation symptoms within 1 hour received BUP-XR 300 mg (assessed as inpatients for 48 hours and outpatients to Day 29). Endpoints were COWS score increase ≥6, independent adjudication of POW, and opioid use.Results: Twenty-six participants (14 male) received BUP-TM, 24 received BUP-XR, and 20 completed the study. After injection, COWS scores decreased from pre-BUP-TM baseline of 14.6 ± 4.1 to 6.9 ± 4.1 at 6 hours and 4.2 ± 3.2 at 24 hours. Most participants (62.5%) experienced maximum COWS scores pre-BUP-XR; 2 experienced a COWS score increase ≥6, occurring at 1 and 2 hours post-BUP-XR. By adjudication, 2/24 participants experienced POW. Irritability, anxiety, nausea, and pain were the most frequent adverse events (AEs) with no serious AEs.Conclusions: Results support increased flexibility for initiating BUP-XR. Initiating BUP-XR 300 mg following a single BUP-TM 4 mg dose was well tolerated. Although some participants initially experienced withdrawal symptoms after injection, significant symptomatic improvement was observed in all participants within 24 hours.

Abstract
BACKGROUND Emerging evidence suggests low-dose buprenorphine (LDB) induction can expand opportunities for buprenorphine induction in patients who are taking taking methadone, short-acting opioid agonists, or who have anxiety about opioid withdrawal. STUDY QUESTION How is a rapid LDB protocol using transdermal buprenorphine tolerated in the hospital? STUDY DESIGN A prospective study of 20 patient encounters (n = 20 patients) with traditional buprenorphine induction before implementation of study protocol (control group) and 37 patient encounters (n = 34 patients) with LDB induction protocol (pilot group). Summary statistics were used to describe demographics, clinical opioid withdrawal scale and pain scores within 24 hours preprotocol and within 24 hours postprotocol initiation, hospital length of stay after protocol initiation, receipt of a buprenorphine prescription at discharge, and prescription activity at 30 days. T test and chi-square tests were used to analyze comparisons. A subset of pilot group patients completed a survey about their experience. RESULTS There were no statistically significant differences in pain and clinical opioid withdrawal scale scores between the pilot and control groups. There were 5 instances of precipitated withdrawal in the pilot group. There was no statistically significant difference in mean discharge time after protocol initiation between the pilot and control groups (P = 0.60). Most patients surveyed described a positive experience with LDB induction. CONCLUSION Hospitalization is a critical time to initiate buprenorphine for patients with opioid use disorder. Our data adds to the growing evidence that LDB induction is feasible for patients taking methadone and short-acting opioid agonists, and that a more rapid induction protocol is generally well-tolerated by patients although precipitated withdrawal is a risk. Finally, our rapid induction protocol did not seem to increase hospital length of stay compared with traditional induction.

Abstract
The United States underwent massive expansion in opioid prescribing from 1990-2010, followed by opioid stewardship initiatives and reduced prescribing. Opioids are no longer considered first-line therapy for most chronic pain conditions and clinicians should first seek alternatives in most circumstances. Patients who have been treated with opioids long-term should be managed differently, sometimes even continued on opioids due to physiologic changes wrought by long-term opioid therapy and documented risks of discontinuation. When providing long-term opioid therapy, clinicians should document opioid stewardship measures, including assessments, consents, medication reconciliation, and offering naloxone, along with the rationale to continue opioid therapy. Clinicians should screen regularly for opioid use disorder and arrange for or directly provide treatment. In particular, buprenorphine can be highly useful for co-morbid pain and opioid use disorder. Addressing other substance use disorders, as well as preventive health related to substance use, should be a priority in patients with opioid use disorder. Patient-centered practices, such as shared decision-making and attending to related facets of a patient's life that influence health outcomes, should be implemented at all points of care.Key messagesAlthough opioids are no longer considered first-line therapy for most chronic pain, management of patients already taking long-term opioid therapy must be individualised.Documentation of opioid stewardship measures can help to organise opioid prescribing and protect clinicians from regulatory scrutiny.Management of resultant opioid use disorder should include provision of medications, most often buprenorphine, and several additional screening and preventive measures.

Abstract
BACKGROUND Opioid use disorder (OUD) is a public health crisis, yet most acute care nurses are not educated to deliver evidence-based OUD care. Hospitalization provides a unique opportunity to initiate and coordinate OUD care in people presenting for other medical-surgical reasons. The aim of this quality improvement project was to determine the impact of an educational program on self-reported competencies of medical-surgical nurses caring for people with OUD at a large academic medical center in the Midwestern United States. METHOD Data were collected from two time points using a quality survey examining self-reported nurse competencies related to (a) assessment, (b) intervention, (c) treatment recommendation, (d) resource use, (e) beliefs, and (f) attitudes toward caring for people with OUD. RESULTS Nurses surveyed before education (T1G1, N = 123) and, after education, those who received the intervention (T2G2, N = 17) and those who did not (T2G3, N = 65) were included. Resource use subscores increased over time (T1G1: x = 3.83, T2G3: x = 4.07, p = .006). Results from the two measurement points found no difference in mean total scores (T1G1: x = 3.53, T2G3: x = 3.63, p = .09). Comparison of mean total scores of nurses who directly received the educational program with those who did not during the second time point showed no improvement (T2G2: x = 3.52, T2G3: x = 3.63, p = .30). CONCLUSIONS Education alone was insufficient in improving self-reported competencies of medical-surgical nurses caring for people with OUD. Findings can be used to inform efforts to increase nurse knowledge and understanding of OUD and to decrease negative attitudes, stigma, and discriminatory behaviors perpetuating care.

Abstract
OBJECTIVE The main objective of the present study was to develop a French-Canadian translation and adaptation of the COWS (i.e., the COWS-FC) for the assessment of opioid withdrawal symptoms in clinical and research settings. METHODS The French-Canadian translation and cultural adaptation of the COWS was performed following guidelines for the translation and cross-cultural adaptation of self-report measures. The steps consisted of (1) initial translation from English to French, (2) synthesis of the translation, (3) back-translation from French to English, (4) expert committee meeting, (5) test of the prefinal version among healthcare professionals and (6) review of final version by the expert committee. The expert committee considered four major areas where the French-Canadian version should achieve equivalence with the original English-version of the COWS. These areas were (1) semantic equivalence; (2) idiomatic equivalence; (3) experiential equivalence and (4) conceptual equivalence. RESULTS Rigorous steps based on the guidelines for the translation and cultural adaptation of assessment tools were followed, which led to a semantically equivalent version of the COWS. After a pretest among healthcare professionals, members from the expert committee agreed upon slight modifications to the French-Canadian version of the COWS to yield a final COWS-FC version. CONCLUSIONS A French-Canadian translation and adaptation of the COWS (i.e., the COWS-FC) was developed. The COWS-FC could be used for the assessment of opioid withdrawal symptoms in clinical and research settings.

Delivering transcutaneous auricular neurostimulation (tAN) to improve symptoms associated with opioid withdrawal: results from a prospective clinical trial. Bioelectron Med 2022; 8:12. [PMID: 35978394 PMCID: PMC9385243 DOI: 10.1186/s42234-022-00095-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Accepted: 07/29/2022] [Indexed: 11/23/2022] Open
Abstract
Background As pharmacological treatments are the primary option for opioid use disorder, neuromodulation has recently demonstrated efficacy in managing opioid withdrawal syndrome (OWS). This study investigated the safety and effectiveness of transcutaneous auricular neurostimulation (tAN) for managing OWS. Methods This prospective inpatient trial included a 30-minute randomized, sham-controlled, double-blind period followed by a 5-day open-label period. Adults with physical dependence on opioids were randomized to receive active or sham tAN following abrupt opioid discontinuation. The Clinical Opiate Withdrawal Scale (COWS) was used to determine withdrawal level, and participants were required to have a baseline COWS score ≥ 13 before enrollment. The double-blind period of the study occurred during the first 30-minutes to assess the acute effects of tAN therapy compared to a sham control. Group 1 received active tAN during both the 30-minute double-blind period and the 5-day open-label period. Group 2 received passive sham tAN (no stimulation) during the double-blind period, followed by active tAN during the 5-day open-label period. The primary outcome was change in COWS from baseline to 60-minutes of active tAN (pooled across groups, accounting for 30-minute delay). Secondary outcomes included difference in change in COWS scores between groups after 30-minutes of active or sham tAN, change in COWS scores after 120-minutes of active tAN, and change in COWS scores on Days 2–5. Non-opioid comfort medications were administered during the trial. Results Across all thirty-one participants, the mean (SD) COWS scores relative to baseline were reduced by 7.0 (4.7) points after 60-minutes of active tAN across both groups (p < 0.0001; Cohen’s d = 2.0), demonstrating a significant and clinically meaningful reduction of 45.9%. After 30-minutes of active tAN (Group 1) or sham tAN (Group 2), the active tAN group demonstrated a significantly greater COWS score reduction than the sham tAN group (41.7% vs. 24.1%; p = 0.036). Participants across both groups achieved an average COWS reduction up to 74.7% on Days 2–5. Conclusion Results demonstrate tAN is a safe and effective non-opioid approach for reducing symptoms of OWS. This study supported an FDA clearance.

Abstract
BACKGROUND Buprenorphine is a life-saving treatment for opioid use disorder (OUD). Low-dose initiation (LDI) is an emerging buprenorphine initiation strategy that circumvents barriers associated with standard initiation. This study aims to describe tolerability and completion of LDI using intravenous (IV) buprenorphine and to define dosing protocols in a cohort of patients hospitalized in an urban academic hospital. METHODS Data was collected via retrospective chart review for IV buprenorphine LDI cases initiated between September 1, 2020 and February 28, 2021. Cases were excluded if diagnostic criteria for OUD was not met, Clinical Opiate Withdrawal Scale (COWS) scores were not recorded, or sublingual (SL) buprenorphine was given within 24 h before IV buprenorphine. Completion of LDI and COWS data were assessed for all cases. Cases were categorized based on adherence to a dosing strategy and LDI indication, including OUD and acute pain, non-prescribed fentanyl exposure, and transition from methadone. RESULTS Seventy-two cases were identified, and thirteen cases were excluded, leaving 59 cases in the population. Of these cases, 72.9% (43/59) tolerated LDI, and 91.5% (54/59) completed buprenorphine initiation. Forty-four (44/59, 75%) cases were adherent. Median duration of LDI within the adherent group was 23.7 h (IQR 22.8-27.0), 37.1 h (IQR 36.2-40.9), and 48.8 h (IQR 47.0-52.4) for the "rapid," "moderate," and "slow" dosing strategies, respectively. CONCLUSIONS IV buprenorphine LDI was tolerated and completed in a majority of patients. Dosing protocols allowed for rapid transition to sublingual buprenorphine. Acute pain or recent methadone or fentanyl exposure may inform IV LDI dosing strategy selection.

Abstract
INTRODUCTION Individuals with opioid use disorder (OUD) are highly represented among the incarcerated population and are frequent utilizers of the emergency department (ED). Medications for opioid use disorder (MOUD) are a recognized treatment option for individuals with OUD. Although the field recognizes the benefits of MOUD, we know little about what mitigating effects MOUD offered in jail might have on post-release ED utilization. METHODS In this retrospective cohort analysis, we searched electronic medical records (EMR) for incarcerations in the Santa Clara County jail between 8/1/2019 and 8/31/2021 for individuals with OUD (N = 4352) and collected demographic and medication administration data for these individuals. Individuals are considered as having received MOUD if they have at least one administration of methadone, naltrexone, or extended release (XR) buprenorphine during their incarceration. We also collected ED visit data from the same EMR for the 28 days following release from the identified incarcerations. Using logistic regression, we compared ED use within 24 h and 28 days for individuals who are incarcerated and treated with MOUD with those not receiving treatment. RESULTS Individuals who received methadone or XR buprenorphine during their incarceration were less likely to present at the 28 days following release than those not receiving treatment, after controlling for age, race, sex assigned at birth, preferred language, and housing status. Most individuals accessing the ED within 28 days of release do so within the first seven days, and the greatest volume occurred in the first 24 h. Individuals released before noon had a lower likelihood of ED presentation within 24 h than those released in the afternoon. CONCLUSIONS Offering methadone and XR buprenorphine to individuals with OUD who are incarcerated is beneficial in mitigating ED utilization within 28 days of release, although further research is needed to understand what other contributing variables, especially those related to follow-up care, could be influencing these results. If possible, release times for individuals could be shifted to the morning to maximize reduction in ED use within 24 h of release. Alternatively, further research should investigate why release times appear to influence ED utilization.

Abstract
Background: Opioid-related inpatient hospital stays are increasing at alarming rates. Unidentified and poorly treated opioid withdrawal may be associated with inpatients leaving against medical advice and increased health care utilization. To address these concerns, we developed and implemented a clinical pathway to screen and treat medical service inpatients for opioid withdrawal. Methods: The pathway process included a two-item universal screening instrument to identify opioid withdrawal risk (Opioid Withdrawal Risk Assessment [OWRA]), use of the validated Clinical Opiate Withdrawal Scale (COWS) to monitor opioid withdrawal symptoms and severity, and a 72-h buprenorphine/naloxone-based treatment protocol. Implementation outcomes including adoption, fidelity, and sustainability of this new pathway model were measured. To assess if there were changes in nursing staff acceptability, appropriateness, and adoption of the new pathway process, a cross-sectional survey was administered to pilot four hospital medical units before and after pathway implementation. Results: Between 2016 and 2018, 72.4% (77,483/107,071) of admitted patients received the OWRA screening tool. Of those, 3.0% (2,347/77,483) were identified at risk for opioid withdrawal. Of those 2,347 patients, 2,178 (92.8%) were assessed with the COWS and 29.6% (645/2,178) were found to be in active withdrawal. A total of 49.5% (319/645) patients were treated with buprenorphine/naloxone. Fifty-seven percent (83/145) of nurses completed both the pre- and post-pathway implementation surveys. Analysis of the pre/post survey data revealed that nurse respondents were more confident in their ability to determine which patients were at risk for withdrawal ( p = .01) and identify patients currently experiencing withdrawal ( p < .01). However, they cited difficulty working with the patient population and coordinating care with physicians. Conclusions: Our study demonstrates a process for successfully implementing and sustaining a clinical pathway to screen and treat medical service inpatients for opioid withdrawal. Standardizing care delivery for patients in opioid withdrawal can also improve nursing confidence when working with this complex population. Plain Language Summary: Opioid-related hospital stays are increasing at alarming rates. Unidentified and poorly treated opioid withdrawal may be associated with patients leaving the hospital against medical advice and increased health care utilization. To address the concerns surrounding an increase in admissions associated with unidentified or poorly treated opioid withdrawal, we developed and implemented a clinical pathway process to consistently screen and treat hospitalized patients for opioid withdrawal. We found that opioid withdrawal screening was successfully implemented and sustained over a 24-month evaluation period. We also found that standardizing care delivery for patients in opioid withdrawal improved nursing confidence when working with this patient population. A robust and ongoing education and training process is important for current staff to ensure knowledge does not erode over time and that training for new staff is embedded in the pathway process to maintain training consistency.

Abstract
BACKGROUND Pain, drug cravings, and opioid withdrawal symptoms can interfere with substance use disorder or opioid tapering treatment goals. AIM This pilot study investigated the feasibility of a protocol designed to test opioid withdrawal symptom relief relative to a sham condition after two consecutive days of hyperbaric oxygen therapy (HBOT) for adults prescribed daily methadone for opioid use disorder. METHOD Using a double-blind protocol, eight adults were randomized to receive either a full 90-minute HBOT dose in a pressurized chamber with 100% oxygen at 2.0 atmospheres absolute (ATA) or a sham condition receiving 21% oxygen (equivalent to room air within the chamber) at a minimal pressure of ≤1.3 ATA. Measures included study retention, treatment satisfaction, and pre- and post-intervention effects for opioid withdrawal symptoms, drug cravings, pain intensity and interference, sleep quality, and mood. RESULTS Study retention and treatment satisfaction was high. All measurements improved more, on average, for participants receiving full-dose HBOT treatment than among participants receiving sham treatments except for clinically observed withdrawal symptoms. The largest positive effects were observed in measurements of pain intensity and drug craving. CONCLUSIONS These pilot results provide evidence to support a fully powered study of HBOT as a potential treatment adjunct for adults receiving methadone for opioid use disorder. Trends towards symptom improvements were detected from pre- to post-HBOT in the full treatment arm versus sham condition. More research into novel non-pharmacologic options to relieve distressing symptoms related to pain and opioid use disorder is essential to improve clinical outcomes.

Abstract
Introduction The degree to which opioid-induced hyperalgesia contributes to the pain experience of patients with chronic pain remains relatively undescribed. The objective of this pilot study was to determine if experimental pain responses improve in patients with chronic pain as they undergo a planned opioid taper. Methods This was a prospective observational study. Seven patients with chronic neuropathic pain on at least 120 mg morphine equivalents/day were enrolled. The participants were followed over the course of an individualized opioid taper to a lower dose. Measures of experimental pain sensitivity, including indicators of central pain modulation, were collected on a biweekly basis; in addition, measures of function and quality of life were collected monthly. The effect of opioid taper on pain responses and functional outcomes over time were examined using longitudinal mixed-effects regression modeling and general linear regression modeling with regularization as a function of baseline dose, end dose, and taper rate. Results In this small sample of patients undergoing highly individualized and variable opioid taper, the opioid taper was significantly associated with improved pain responses to the cold-pressor test, with the pain threshold on average increasing by 1.14 s every 6 weeks (p = 0.0084, 95% confidence interval [CI] for 6-week change 0.3039–2.0178) and pain tolerance on average increasing by 2.87 s every 6 weeks (p = 0.0026, 95% CI for 6-week change 1.02–4.7277). Taper-related changes in central pain modulation were not observed, although conditioned modulation trended toward improvement by the completion of opioid taper. Similarly, no declines in function and quality of life were observed with the opioid taper, suggesting stability despite decreased opioid dose. Conclusions Opioid taper was associated with improvements in experimental pain responses without a decline in function and quality of life, suggestive of diminished opioid-induced hyperalgesia in this clinical sample.

Abstract
Thousands of individuals die each year from opioid-related overdoses. While naloxone (Narcan®) is currently the most widely employed treatment to reverse opioid toxicity, high or repeated doses of this antidote often lead to precipitated opioid withdrawal (POW). We hypothesized that a slow linear release of naloxone from a nanoparticle would induce fewer POW symptoms compared to high-dose free naloxone. First, we measured the acute impact of covalent naloxone nanoparticles (Nal-cNPs) on morphine-induced antinociception in the hotplate test. We found that Nal-cNP treatment blocked the antinociceptive effect of morphine within 15 min of administration. Next, we tested the impact of Nal-cNPs on POW symptoms in male morphine-dependent mice. To induce morphine dependence, mice were treated with 5 mg/kg morphine (or saline) twice-daily for six consecutive days. On day 7 mice received 5 mg/kg morphine (or saline) injections 2 hr prior to receiving treatment of either unmodified free naloxone, a high or low dose of Nal-cNP, empty nanoparticle (cNP-empty), or saline. Behavior was analyzed for 0-6 hr followed by 24 and 48 hr time points after treatment. As expected, free naloxone induced a significant increase in POW behavior in morphine-dependent mice compared to saline-treated mice upon free naloxone administration. In comparison, reduced POW behavior was observed with both doses of Nal-cNP. Side effects of Nal-cNP on locomotion and fecal boli production were measured and no significant side-effects were observed. Overall, our data show that sustained release of naloxone from a covalent nanoparticle does not induce severe POW symptoms in morphine-dependent mice.

Abstract
Background: Coping with pain is a commonly reported motive for opioid misuse. Opioids also provide relief of stress and negative affect and thus are often misused to cope with these emotional states. Although several studies have investigated coping motives in people who misuse opioids, it remains unclear whether pain coping and negative affect coping are distinct or overlapping motives for misuse. Objectives: In this study, we examined opioid use motives (enhancement, social, negative affect coping, and pain coping) in a sample of 52 adults seeking treatment for opioid use disorder. We used an adaptation of the Drug Use Motives Questionnaire that included an additional 5 items to assess pain coping motives for use. Results: Results indicated that pain coping was not significantly associated with other motives for use, including negative affect coping. Pain coping motives were strongly correlated with both pain severity (r = .51) and pain interference (r = .39), but not anxiety severity. Conversely, negative affect coping motives were strongly correlated with anxiety severity (r = .45), but not pain severity or interference. Conclusions: These results suggest that pain coping motives may be distinct from negative affect coping motives and should be assessed separately.

Abstract
BACKGROUND This work evaluated the psychometric properties of the single-item Opioid Craving Visual Analog Scale (OC-VAS) for opioid use disorder (OUD). METHODS Psychometric evaluation of the OC-VAS (range: 0-100 mm) was supported by Subjective Opiate Withdrawal Scale (SOWS) item 16 and total score, Clinical Opiate Withdrawal Scale (COWS) scores, and the 36-Item Short-Form Health Survey, using data from phase 3 study (NCT02357901; N = 487) participants who received randomized treatment and completed the OC-VAS at screening. Descriptive properties, test-retest reliability, construct validity, known-groups validity, and responsiveness were assessed. Interpretation of meaningful change and predictive validity were also explored. RESULTS Descriptive properties for the OC-VAS at screening did not provide evidence of problematic floor/ceiling effects or missingness. The test-retest reliability was established by weekly intraclass correlations >0.70. At the screening and end of the study, the strong positive correlations between OC-VAS and SOWS Total/Item 16 score and the significant OC-VAS differences among COWS severity groups supported construct validity and known-groups (discriminating ability) validity, respectively. The associations between the changes in OC-VAS and in supporting measures/opioid use from screening to the end of the study demonstrated responsiveness and the ability to detect change in clinical status. During the induction and randomization treatment periods, significant relationships were identified between OC-VAS score and subsequent opioid use. CONCLUSIONS This psychometric evaluation of the OC-VAS performed on a large OUD patient population provides evidence to support its use to measure the severity of opioid craving and its ability to predict opioid use.

Abstract
STUDY OBJECTIVE Emergency departments (ED) are critical touchpoints for encounters among patients with opioid use disorder (OUD), but implementation of ED initiated treatment and harm reduction programs has lagged. We describe national patient, visit and hospital-level characteristics of ED OUD visits and characterize EDs with high rates of OUD visits in order to inform policies to optimize ED OUD care. METHODS We conducted a descriptive, cross-sectional study with the 2017 Nationwide Emergency Department Sample (NEDS) from the Healthcare Cost and Utilization Project, using diagnostic and mechanism of injury codes from ICD-10 to identify OUD related visits. NEDS weights were applied to generate national estimates. We evaluated ED visit and clinical characteristics of all OUD encounters. We categorized hospitals into quartiles by rate of visits for OUD per 1000 ED visits and described the visit, clinical, and hospital characteristics across the four quartiles. RESULTS In 2017, the weighted national estimate for OUD visits was 1,507,550. Overdoses accounted for 295,954. (19.6%) of visits. OUD visit rates were over 8× times higher among EDs in the highest quartile of OUD visit rate (22.9 per 1000 total ED visits) compared with EDs in the lowest quartile of OUD visit rate (2.7 per 1000 ED visits). Over three fifths (64.2%) of all OUD visits nationwide were seen by the hospitals in the highest quartile of OUD visit rate. These hospitals were predominantly in metropolitan areas (86.2%), over half were teaching hospitals (51.7%), and less than a quarter (23.3%) were Level 1 or Level 2 trauma centers. CONCLUSION Targeting initial efforts of OUD care programs to high OUD visit rate EDs could improve care for a large portion of OUD patients utilizing emergency care.

Abstract
Difelikefalin, a selective kappa‐opioid receptor agonist with limited central nervous system penetration, is being developed for the treatment of chronic pruritic conditions. This randomized, double‐blind, active‐ and placebo‐controlled, four‐way crossover study was designed to evaluate the abuse potential of difelikefalin in healthy recreational polydrug users. Using a 4 × 4 Williams design, nondependent adult users of opioids and hallucinogens (N = 44) were randomized to receive single intravenous (i.v.) injections of difelikefalin at supratherapeutic doses (5 and 15 mcg/kg); pentazocine (0.5 mg/kg), a schedule IV mu‐opioid partial agonist and kappa‐opioid receptor agonist; and placebo. The abuse potential of difelikefalin was compared with pentazocine and placebo using the maximal score (maximum effect [Emax]) of the Drug Liking visual analog scale (VAS; primary end point), along with multiple secondary end points of subject‐rated measures and pupillometry. Difelikefalin produced significantly lower Drug Liking VAS Emax, and lower peak positive, sedative, and perceptual effects compared with pentazocine. These effects of difelikefalin were small, brief, and not dose‐dependent, although marginally greater than those observed with placebo. Neither dose of difelikefalin elicited significant negative or hallucinogenic effects. On end‐of‐session measures of overall drug liking and willingness to take the drug again, difelikefalin did not differ from placebo, indicating subjects neither liked nor disliked the effects overall and did not feel motivated to take the drug again. Consistent with its lack of mu agonist activity, difelikefalin did not induce miosis compared with pentazocine. All treatments were generally well‐tolerated. This study indicates that difelikefalin presents a low potential for abuse.

Abstract
BACKGROUND Impaired cognitive functions, particularly executive function, predicts poor treatment success in people with substance use disorders. The current study investigated the effect of receiving adjunct cognitive rehabilitation and baseline executive function (EF) measures on treatment response among people with opioid use disorder (OUD). METHOD The analysis sample consisted of 113 participants with OUD who were discharged from a compulsory court-mandated methadone maintenance treatment (MMT) and followed for 3 months. We used the Backward digit span/Auditory verbal learning, Stroop, and Trail making tests to assess the three measures of EF, including working memory, inhibition, and shifting, respectively. Treatment response was operationalized as (1) treatment retention and (2) the number of positive urine tests for morphine during 3-month follow-up periods. The study used Cox's proportional hazards model and linear mixed model to identify predictive factors. RESULTS Lower Stroop interference scores predicted increased length of stay in treatment (χ2 = 33.15, P < 0.001). The linear mixed model showed that scores on auditory verbal learning test and group intervention predicted the number of positive urine tests during a 3-month follow-up. CONCLUSION Working memory and inhibitory control, as well as receiving cognitive rehabilitation, could be potentially considered as predictors of treatment response for newly MMT admitted patients with OUD. Assessment of EF before treatment initiation may inform treatment providers about patient's cognitive deficits that may interfere with therapeutic interventions.

Abstract
Opioid use disorder (OUD) is characterized by heightened cognitive, physiological, and neural responses to opioid-related cues that are mediated by mesocorticolimbic brain pathways. Craving and withdrawal are key symptoms of addiction that persist during physiological abstinence. The present study evaluated the relationship between the brain response to drug cues in OUD and baseline levels of craving and withdrawal. We used functional magnetic resonance imaging (fMRI) to examine brain responses to opioid-related pictures and control pictures in 29 OUD patients. Baseline measures of drug use severity, opioid craving, and withdrawal symptoms were assessed prior to cue exposure and correlated with subsequent brain responses to drug cues. Mediation analysis was conducted to test the indirect effect of drug use severity on brain cue reactivity through craving and withdrawal symptoms. We found that baseline drug use severity and opioid withdrawal symptoms, but not craving, were positively associated with the neural response to drug cues in the nucleus accumbens, orbitofrontal cortex, and amygdala. Withdrawal, but not craving, mediated the effect of drug use severity on the nucleus accumbens' response to drug cues. We did not find similar effects for the neural responses to stimuli unrelated to drugs. Our findings emphasize the central role of withdrawal symptoms as the mediator between the clinical severity of OUD and the brain correlates of sensitization to opioid-related cues. They suggest that in OUD, baseline withdrawal symptoms signal a high vulnerability to drug cues.

Abstract
In treating chronic and acute pain, opioids are widely used. Although they do provide analgesia, their usage does come with adverse events (AEs). One of the most burdensome is opioid-induced bowel dysfunction, and more specifically opioid-induced constipation (OIC). The pathogenesis of these AEs is well known as the consequence of the action of opioids on m-receptors in the enteric nervous system. In recent years, medicines counteracting this specific action at the receptors have been registered for clinical use: the peripherally acting μ-opioid receptor antagonists (PAMORAs). The knowledge of their comparative efficacy and tolerability is very important for physicians and patients in opioid therapy. This systematic review of the existing literature on PAMORAs aimed to study the relative clinical advantages and disadvantages. The most important data banks, including "PubMed," "Embase," "CT.gov," "ICTRP" and "CINAHL" were used to find the published material on PAMORAs. The selected publications were examined to systematically analyze the efficacy and safety of the four existing PAMORAs. All of the medications are superior to placebo in reducing OIC. There are few published data on alvimopan used to treat OIC, and it is only indicated for the treatment of post-abdominal surgery ileus. Methylnaltrexone is studied mainly in its subcutaneous (SC) formulation. When used in its oral formulation, it seems more rapid than naloxegol and placebo in the reduction of OIC. Naldemedine is able to produce more spontaneous bowel movements (SBMs) when compared to alvimopan and naloxegol. Tolerability was found to be similar for all of them. In particular, they affect the gastrointestinal tract (GI), with flatulence and diarrhea, especially at high dosages. For some of them, nasopharyngitis and abdominal pain were observed as treatment adverse effects (TEAs). Several cardiovascular TEAs were reported after methylnaltrexone use, but it is not clear whether they were consequences of the drug or related to the general conditions of the patients. Considering the existing data, naloxegol and naldemedine seem to be the best choices, with a higher number of spontaneous bowel movements following naldemedine administration.

Abstract
INTRODUCTION The need for innovative approaches to address the opioid epidemic in the United States is widely recognized. Many challenges exist to addressing this epidemic, including the obstacles outpatient substance use treatment practices face in implementing measurement-based care (MBC), quality measurement systems, and evidence-based treatments. Also, there are insufficient opportunities for clinicians in these settings to participate in research, resulting in diminished translation of research findings into community-based practice. To address these challenges, the Addiction Medicine Practice-Based Research Network (AMNet) was developed to facilitate the uptake of MBC in outpatient practices via implementation of patient-reported assessments and quality of care performance measures to improve patient outcomes. This network will offer clinicians in outpatient settings (not incuding opioid treatment programs [OTPs]) the opportunity to participate in future substance use disorder treatment research studies. METHODS A key step in the development of AMNet was the selection of substance use-specific assessment tools and quality of care performance measures for incorporation into the American Psychiatric Association's mental health patient registry, PsychPRO. A scoping review and multi-step consensus-based process were used to identify, review and select candidate assessment tools and quality of care performance measures for opioid use disorders (OUD) and substance use disorders (SUD). RESULTS Following a consensus-based methodology, 12 standardized assessment tools and 3 quality of care performance measures for OUD and SUD were selected to help facilitate the implementation of MBC and quality improvement for AMNet participants. These tools were further categorized as core and optional. CONCLUSION By offering a collection of carefully vetted assessment tools and quality measures through PsychPRO, AMNet will help participating clinicians with the systematic uptake of MBC and delivery of evidence-based treatment for patients with SUD. Also, AMNet will act as a centralized repository of data collected from patients and clinicians in non-OTP outpatient addiction medicine practices and serve as a platform for opioid treatment research.

Abstract
OBJECTIVES The Clinical Opiate Withdrawal Scale (COWS) is a validated, commonly used tool to objectively quantify withdrawal symptoms, often in anticipation of treatment with buprenorphine. Our primary aim was to determine the agreement between emergency department (ED) nurses compared with emergency physicians in determining this score in ED patients who presented for opioid withdrawal treatment. Secondarily, we wanted to investigate the safety of buprenorphine induction in the ED setting. METHODS Scoring for opioid withdrawal using the COWS was performed by ED clinicians and ED nurses independently on 120 patients. In addition to overall concordance, agreement (weighted kappa) was calculated between the 2 scores by various cutoffs: overall severity, COWS ≥ 5, and the 11 different individual measures. Patient documents also were reviewed for complications that could be possibly linked to buprenorphine induction. RESULTS Our study sample of 120 subjects was 77% Hispanic and 78.3% male. The clinicians assigned a median interquartile range overall COWS score of 6 (2-12), which categorizes as mild withdrawal. Seventy-eight (65%) subjects met the criteria of withdrawal (≥ 5 COWS) and 69 (58%) received an induction dose of buprenorphine (range 2 mg-24 mg) during the ED visit. No adverse effects or worsening withdrawal were reported. The overall observed concordance, based on severity withdrawal categorization, for all clinician pairs, was 67.5% (81/120) (95% confidence interval [CI], 58.7-75.2%). The weighted kappa for that concordance was 0.55 (95% CI, 0.43-0.67), giving a moderate strength of agreement. When data are dichotomized by COWS score ≥5, concordance was 82.5% (99/120) (95% CI, 74.7%-88.3%) and the weighted kappa was 0.65 (95% CI, 0.51-0.78), indicating substantial agreement. The breakdown by the 11 factors that constitute COWS showed only substantial agreement for pulse measurement. CONCLUSION The agreement between ED clinicians and nurses for the overall COWS scoring in patients presenting for opioid withdrawal treatment was substantial. COWS scoring by ED nurses may help expedite treatment with buprenorphine on presentation.

Abstract
OBJECTIVE To evaluate the long-term safety of NKTR-181, a novel mu-opioid receptor agonist that may have reduced human abuse potential, in patients with moderate to severe chronic low back pain (CLBP) or other chronic noncancer pain (CNP). DESIGN Uncontrolled, multicenter, open-label, long-term study of NKTR-181 comprised of three periods: screening (≤21 days), treatment (52 weeks), and safety follow-up (∼14 days after the last dose of NKTR-181). SETTING Multicenter, long-term clinical research study. METHODS NKTR-181 administered at doses of 100-600 mg twice daily (BID) was evaluated in opioid-naïve and opioid-experienced patients. Patients were enrolled de novo or following completion of the randomized, placebo-controlled phase 3 efficacy study (SUMMIT-07). Safety assessments included adverse event documentation, measurements of opioid withdrawal, and clinical laboratory tests. Effectiveness was assessed using the modified Brief Pain Inventory Short Form (mBPI-SF). RESULTS The study enrolled 638 patients. The most frequently reported treatment-emergent adverse events (TEAEs) were constipation (26%) and nausea (12%). Serious TEAEs, reported in 5% of patients, were deemed by investigators to be unrelated to NKTR-181. There were no deaths or reported cases of respiratory depression. A sustained reduction in mBPI-SF pain intensity and pain interference from baseline to study termination was observed throughout treatment. Only 2% of patients discontinued NKTR-181 due to lack of efficacy, and 11% discontinued due to treatment-related AEs. NKTR-181 doses of up to 600 mg BID were generally well tolerated, and patients experienced low rates of opioid-related adverse events. CONCLUSIONS The study results support the premise that NKTR-181 is a safe and effective option for patients with moderate to severe CLBP or CNP.

Abstract
Objective: The purpose of this study was to integrate acupuncture within the standard of care during outpatient opioid tapering and assess impact of this treatment on cumulative withdrawal symptoms, psychologic distress, and pain. Methods: This prospective randomized controlled pilot study administered the National Acupuncture Detoxification Association protocol following monthly opioid tapering. A total of 9 participants were randomized into the intervention group and compared with 6 participants who underwent the standard of care for outpatient opioid tapering. All providers prescribing medication management to both groups were blinded. Psychologic distress was evaluated using the hospital anxiety and depression scale (HADS). The clinical institute narcotic assessment (CINA) measured subjective withdrawal symptoms and pain was assessed using the numerical rating scale (NRS). Results: Overall anxiety appeared slightly higher in the acupuncture group (HADS 7.0 compared with 6.5), however, depression was lower when compared with the standard of care group (HADS 4.0 compared with 6.5). The standard of care group reported more intense withdrawal symptoms (CINA 9.0 compared with 3.5) as well as higher pain scores (NRS 6.5 compared with 5.0). There were no statistically significant differences among the standard of care and acupuncture groups. Conclusions: This study suggests that auricular acupuncture may be implemented within the standard of care for patients undergoing outpatient opioid weaning regimens. Although results were not statistically significant, they support future research and reveal a promising expansion of treatment options for patients physically dependent on opioid medication.

Abstract
Regulations for new drug approvals require stringent safety testing and efficacy trial programs. The approval process for generic drugs, however, is significantly streamlined. Bioavailability data can substitute for new rounds of efficacy trials, thereby both decreasing time to approval and reducing the costs required for new studies. This regulatory choice has not been available when generic drugs are offered in a controlled release format such as a subcutaneous depot, transdermal patch or implant. The purpose of this review is to suggest that the approval of generic drugs in inert controlled release envelopes should be eligible for similar regulatory relief. Proof for this concept is provided by the example of the numerous controlled release buprenorphine products. Buprenorphine is a generic opioid used since the 1980s in tablet form to treat pain and to treat opioid addiction. Long-acting, inert delivery vehicles for the drug have become available for the same indications. Safety and bioavailability profiles of the long-acting products are the same or improved over the parent product. A review of the long-acting drugs provides compelling evidence to recommend that generic drug-controlled release products may be eligible for alternative regulatory programs.

Abstract
Introduction/Background: A rough, visual estimate of pupil size is used in grading the severity of opioid withdrawal. Few studies have examined the clinical utility of more precise automated pupillometry measurements. Methods: This prospective cohort study enrolled 27 patients receiving opioid agonist therapy (OAT) to treat cravings or withdrawal during an acute hospitalization. Six sets of automated pupillometry measurements were obtained at regular intervals before and after administration of OAT. Clinical Opiate Withdrawal Scale measurements were performed pre and post OAT. Primary outcomes included pupil size in dark and bright illumination (mm). Latency of the pupillary light response (s), constriction and dilation velocity (mm/s), and percent constriction (%) were secondary outcomes. Results: The mean predosing pupil size in dark and bright illumination was 4.33 ± 1.40 mm and 2.96 ± 0.79 mm, respectively. A significantly decreased mean pupil size was first detected at 15 minutes postdosing (4.01 ± 1.34 mm, P = 0.0115 for dark illumination; 2.71 ± 0.72 mm, P = 0.0003 for bright illumination) and this reduction in pupil size persisted at later postdosing timepoints. Those with Clinical Opiate Withdrawal Scale <5 after dosing had a greater decrease in dark pupil size (10.6% ± 13.2 vs 3.2% ± 3.2, P = 0.043). There was no significant change in the remaining pupil reactivity parameters. Conclusions: Automated pupillometry demonstrated a small but significant change in mean pupil size that occurred within 15 minutes of OAT dosing and was associated with low withdrawal scores. This pilot may inform future work to incorporate pupillometry measurement into OAT dosing assessments.

Abstract
BACKGROUND AND OBJECTIVES Individuals exposed to fentanyl are at risk of precipitated withdrawal using typical buprenorphine/naloxone induction procedures. METHODS This case series describes buprenorphine/naloxone inductions of four individuals who tested positive for fentanyl. RESULTS Buprenorphine-precipitated withdrawal was observed in two individuals who completed a conventional buprenorphine/naloxone induction strategy. Two more individuals completed a revised buprenorphine/naloxone induction strategy that did not precipitate withdrawal. DISCUSSION AND CONCLUSION Using multiple 2 mg doses of buprenorphine/naloxone in patients already in mild/moderate withdrawal improved outcomes. SCIENTIFIC SIGNIFICANCE Persons who use illicit fentanyl might be less likely to experience precipitated withdrawal from this revised buprenorphine/naloxone induction strategy.

Abstract
Local efforts to provide treatment for individuals with substance use disorder have had some success in addressing the continued nationwide drug epidemic. A nurse-led withdrawal and stabilization program was developed that includes an interdisciplinary team of physicians, advanced practice providers, nurses, social workers, and substance abuse counselors. Utilizing a shared vision of optimal patient care, we describe how principles of high reliability were incorporated to build a successful program within a community hospital setting from the design of the unit, development of treatment protocols, staffing, and ongoing program refinement that is based on patient and program staff feedback to final thoughts for future program changes.
