RESUMO

Mitragyna speciosa, also known as kratom, has been reported to have a broad range of pharmacological properties. Freshly harvested leaves and their water extracts are consumed in Southeast Asia while preparations made from dried leaf material are consumed in Western countries. Our study evaluated the phytochemical composition of freshly harvested kratom leaves using LCMS/MS analysis of water and ethanol liquid extracts. Mitragynine and its congeners, including 7-hydroxymitragynine, speciocilliatine, speciogynine, paynantheine, as well as bioactive phenolics including chlorogenic acid, o-coumaric acid, quercitrin, and rutin were identified. However, 7-hydroxymitragynine was detected solely in the water-liquid extract. Currently, unknown compounds were also present in the chromatograms and mass spectra. The study results support that 7-hydroxymitragynine is a post-harvest oxidative derivative or metabolite of mitragynine. Further rigorous and comprehensive evaluations of the phytochemical composition of freshly harvested kratom leaves utilising advanced spectrometric methods are needed to establish the full spectrum of phytochemicals within the plant.

RESUMO

PURPOSE OF REVIEW: Kratom plant, products derived from the plant, and plant phytochemicals are of great interest among researchers, clinicians, and consumers. However, there is a paucity of rigorously collected scientific data on their risk/safety profile and public health impact. This scoping review discusses original research articles published between 2022 and 2023. It focuses on identifying publication gaps on topics related to epidemiology, public health, and risk/safety profiles comparing evidence collected by researchers from Southeast Asia and the West. RECENT FINDINGS: Our review of the Scopus database identified a total of 55 publications, including clinical case reports and case series reports, surveys, studies enrolling human participants, and publications based on large-scale national surveys or large-scale national or international health system database records. SUMMARY: Overall, there is dearth of reliable data on key epidemiological factors, including the prevalence rates, and on objective and reliable indices of the risk/safety profiles. Rigorous and systematic studies including improved epidemiological surveillance, human laboratory, and controlled clinical studies are urgently needed to advance our understanding of public health consequences of consuming kratom and kratom-derived products and to improve our understanding of their risk/safety profile and additional analytical studies to better inform development of needed regulatory oversight.

RESUMO

Mitragyna speciosa Korth also known as kratom, is an herbal drug preparation for its therapeutic properties and opioid-replacement therapy. Kratom is consumed in a brewed decoction form in Malaysia and to date, no studies have characterized its chemical and toxicity profile. Thus, this study aims to evaluate kratom decoction's safety and toxicity profile after 28 days of treatment. Mitragynine content was quantified in kratom decoction and used as a marker to determine the concentration. Male and female Sprague Dawley rats were orally treated with vehicle or kratom decoction (10, 50 or 150 mg/kg) and two satellite groups were treated with vehicle and kratom decoction (150 mg/kg). Blood and organs were collected for hematology, biochemical and histopathology analysis at the end of treatment. No mortality was found after 28 days of treatment and no significant changes in body weight and hematology profile, except for low platelet count. High amounts of uric acid, AST, ALT and alkaline phosphatase were found in the biochemical analysis. Histological investigation of the heart and lungs detected no alterations except for the kidney, liver and brain tissues. In conclusion, repeated administration of kratom decoction provided some evidence of toxicity in the kidney and liver with no occurrence of mortality.

RESUMO

Importance: An increasing number of emergency departments (EDs) are initiating buprenorphine for opioid use disorder (OUD) and linking patients to ongoing community-based treatment, yet community-based clinician and staff perspectives regarding this practice have not been characterized. Objective: To explore perspectives and experiences regarding ED-initiated buprenorphine among community-based clinicians and staff in geographically distinct regions. Design, Setting, and Participants: This qualitative study reports findings from Project ED Health, a hybrid type 3 effectiveness-implementation study designed to evaluate the impact of implementation facilitation on ED-initiated buprenorphine with referral to ongoing medication treatment. Clinicians and staff from community-based treatment programs were identified by urban academic EDs as potential referral sites for ongoing OUD treatment in 4 cities across the US in a formative evaluation as having the capability to continue medication treatment. Focus groups were held from April 1, 2018, to January 11, 2019, to examine community OUD treatment clinician and staff perspectives on accepting patients who have received ED-initiated buprenorphine. Data were analyzed from August 2020 to August 2022. Main Outcomes and Measures: Data collection and analysis were grounded in the Promoting Action on Research Implementation in Health Services (PARIHS) implementation science framework, focusing on domains including evidence, context, and facilitation. Results: A total of 103 individuals (mean [SD] age, 45.3 [12.0] years; 76 female and 64 White) participated in 14 focus groups (groups ranged from 3-22 participants). Participants shared negative attitudes toward buprenorphine and variable attitudes toward ED-initiated buprenorphine. Prominent barriers included the community site treatment capacity and structure as well as payment and regulatory barriers. Perceived factors that could facilitate this model included additional substance use disorder training for ED staff, referrals and communication, greater inclusion of peer navigators, and addressing sociostructural marginalization that patients faced. Conclusions and Relevance: In this study of community-based clinicians and staff positioned to deliver OUD treatment, participants reported many barriers to successful linkages for patients who received ED-initiated buprenorphine. Strategies to improve these linkages included educating communities and programs, modeling low-barrier philosophies, and using additional staff trained in addiction as resources to improve transitions from EDs to community partners.

RESUMO

INTRODUCTION: Clinical pharmacists are well positioned to enhance efforts to promote emergency department (ED)-initiated buprenorphine to treat opioid use disorder (OUD). Among clinical pharmacists in urban EDs, we sought to characterize barriers and facilitators for ED-initiated buprenorphine to inform future implementation efforts and enhance access to this highly effective OUD treatment. METHODS: This study was conducted as a part of Project ED Health (CTN-0069, NCT03023930), a multisite effectiveness-implementation study aimed at promoting ED-initiated buprenorphine that was conducted between April 2017 and July 2020. Data collection and analysis were grounded in the Promoting Action on Research Implementation in Health Services (PARIHS) framework to assess perspectives on the relationship between 3 elements: evidence for buprenorphine, the ED context, and facilitation needs to promote ED-initiated buprenorphine. The study used an iterative coding process to identify overlapping themes within these 3 domains. RESULTS: The study conducted eight focus groups/interviews across four geographically disparate EDs with 15 pharmacist participants. We identified six themes. Themes related to evidence included (1) varied levels of comfort and experience among pharmacists with ED-initiated buprenorphine that increased over time and (2) a perception that patients with OUD have unique challenges that require guidance to optimize ED care. With regards to context, clinical pharmacists identified: (3) their ability to clarify scope of ED care in the context of unique pharmacology, formulations, and regulations of buprenorphine to ED staff, and that (4) their presence promotes successful program implementation and quality improvement. Participants identified facilitation needs including: (5) training to promote practice change and (6) ways to leverage already existing pharmacy resources outside of the ED. CONCLUSION: Clinical pharmacists play a unique and critical role in the efforts to promote ED-initiated buprenorphine. We identified 6 themes that can inform pharmacist-specific interventions that could aid in the successful implementation of this practice.

RESUMO

Importance: Emergency department (ED)-initiated buprenorphine for the treatment of opioid use disorder (OUD) is underused. Objective: To evaluate whether provision of ED-initiated buprenorphine with referral for OUD increased after implementation facilitation (IF), an educational and implementation strategy. Design, Setting, and Participants: This multisite hybrid type 3 effectiveness-implementation nonrandomized trial compared grand rounds with IF, with pre-post 12-month baseline and IF evaluation periods, at 4 academic EDs. The study was conducted from April 1, 2017, to November 30, 2020. Participants were ED and community clinicians treating patients with OUD and observational cohorts of ED patients with untreated OUD. Data were analyzed from July 16, 2021, to July 14, 2022. Exposure: A 60-minute in-person grand rounds was compared with IF, a multicomponent facilitation strategy that engaged local champions, developed protocols, and provided learning collaboratives and performance feedback. Main Outcomes and Measures: The primary outcomes were the rate of patients in the observational cohorts who received ED-initiated buprenorphine with referral for OUD treatment (primary implementation outcome) and the rate of patients engaged in OUD treatment at 30 days after enrollment (effectiveness outcome). Additional implementation outcomes included the numbers of ED clinicians with an X-waiver to prescribe buprenorphine and ED visits with buprenorphine administered or prescribed and naloxone dispensed or prescribed. Results: A total of 394 patients were enrolled during the baseline evaluation period and 362 patients were enrolled during the IF evaluation period across all sites, for a total of 756 patients (540 [71.4%] male; mean [SD] age, 39.3 [11.7] years), with 223 Black patients (29.5%) and 394 White patients (52.1%). The cohort included 420 patients (55.6%) who were unemployed, and 431 patients (57.0%) reported unstable housing. Two patients (0.5%) received ED-initiated buprenorphine during the baseline period, compared with 53 patients (14.6%) during the IF evaluation period (P < .001). Forty patients (10.2%) were engaged with OUD treatment during the baseline period, compared with 59 patients (16.3%) during the IF evaluation period (P = .01). Patients in the IF evaluation period who received ED-initiated buprenorphine were more likely to be in treatment at 30 days (19 of 53 patients [35.8%]) than those who did not 40 of 309 patients (12.9%; P < .001). Additionally, there were increases in the numbers of ED clinicians with an X-waiver (from 11 to 196 clinicians) and ED visits with provision of buprenorphine (from 259 to 1256 visits) and naloxone (from 535 to 1091 visits). Conclusions and Relevance: In this multicenter effectiveness-implementation nonrandomized trial, rates of ED-initiated buprenorphine and engagement in OUD treatment were higher in the IF period, especially among patients who received ED-initiated buprenorphine. Trial Registration: ClinicalTrials.gov Identifier: NCT03023930.

RESUMO

Mitragynine exerts its analgesic effect mainly via opioid receptors activation. Additionally, the effect may be mediated via mitragynine's anti-inflammatory property and non-opioid receptor pain pathways, namely through the TRPV1 receptor. No studies identify hitherto, hence, the current study aimed to investigate the mitragynine's analgesic effect via the anti-inflammatory property, non-opioid receptor (TRPV1) and the effective dose (ED) to alleviate pain. Male and female Sprague Dawley rats were pre-treated intraperitoneally with either mitragynine (1, 5, 10, 13, 15 or 30 mg/kg), vehicle, or indomethacin (1 mg/kg) 30 min before inducing inflammatory pain using acetic acid. The writhes and pain-related withdrawal behaviour occurrence were counted within a 1-h duration. Percentage of writhes inhibition, pain-related withdrawal behaviour aggregate, ED50 and ED95 were determined. The body temperature was recorded and TRPV1 expression in the rats' brains was measured. Mitragynine (except 1 mg/kg) significantly reduced the number of writhes compared with the vehicle administered group. Mitragynine (30 mg/kg) demonstrated 99.5% inhibition of writhing behaviour and low withdrawal behaviour score compared with vehicle and indomethacin and successfully blocked the hypothermia induced by acetic acid. The overall ED50 and ED95 values of mitragynine were 3.62 and 20.84 mg/kg, respectively. The percentage of writhing inhibition and withdrawal behaviour were similar in both genders. Mitragynine (15 and 30 mg/kg) significantly reduced the TRPV1 expression in the brain of the rats. Mitragynine alleviated pain-like behaviour and showed analgesic effects via anti-inflammatory and non-opioid receptor pathways. The findings also suggest that mitragynine might regulate some physiological functions of the rat.

RESUMO

OBJECTIVE: We assessed the frequency of emergency department (ED) HIV and hepatitis C (HCV) screening in a high-risk cohort of ED patients with untreated opioid use disorder (OUD). METHODS: This analysis used data from a prospective, observational study of English-speaking adults with untreated OUD enrolled from April 2017 to December 2018 in 4 urban, academic EDs. Two cohorts were defined for this analysis by self-reported negative/unknown status for HIV (cohort 1) and HCV (cohort 2). Sites featured structured screening programs throughout the entire enrollment period for HIV and during at least part of the enrollment period for HCV. We calculated the proportion tested for HIV and HCV during the study enrollment ED visit. RESULTS: Among 394 evaluated ED patients, 328 of 394 (83.2%) were not tested for HIV or HCV and 244 of 393 (62.1%) lacked a usual medical care provider. In cohort 1, 375 reported negative or unknown HIV status; 59/375 (15.7%) overall and 33/218 (15.1%) of those reporting recent injection drug use were tested for HIV. In cohort 2, 231 reported negative of unknown HCV status; 22/231 (9.5%) overall and 9/98 (9.2%) of those reporting recent injection drug use were tested for HCV. The proportion tested by the ED ranged from 3% to 25% for HIV and 4% to 32% for HCV across study sites. CONCLUSIONS: Emergency department HIV and HCV screening remains infrequent among patients with untreated OUD, including those who inject drugs, even in EDs committed to screening. Targeted HIV/HCV screening should be considered as an adjunct strategy until the ideal of universal screening is more fully achieved.

RESUMO

Importance: Emergency departments (EDs) are increasingly initiating treatment for patients with untreated opioid use disorder (OUD) and linking them to ongoing addiction care. To our knowledge, patient perspectives related to their ED visit have not been characterized and may influence their access to and interest in OUD treatment. Objective: To assess the experiences and perspectives regarding ED-initiated health care and OUD treatment among US patients with untreated OUD seen in the ED. Design, Setting, and Participants: This qualitative study, conducted as part of 2 studies (Project ED Health and ED-CONNECT), included individuals with untreated OUD who were recruited during an ED visit in EDs at 4 urban academic centers, 1 public safety net hospital, and 1 rural critical access hospital in 5 disparate US regions. Focus groups were conducted between June 2018 and January 2019. Main Outcomes and Measures: Data collection and thematic analysis were grounded in the Promoting Action on Research Implementation in Health Services (PARIHS) implementation science framework with evidence (perspectives on ED care), context (ED), and facilitation (what is needed to promote change) elements. Results: A total of 31 individuals (mean [SD] age, 43.4 [11.0] years) participated in 6 focus groups. Twenty participants (64.5%) identified as male and most 13 (41.9%) as White; 17 (54.8%) reported being unemployed. Themes related to evidence included patients' experience of stigma and perceived minimization of their pain and medical problems by ED staff. Themes about context included the ED not being seen as a source of OUD treatment initiation and patient readiness to initiate treatment being multifaceted, time sensitive, and related to internal and external patient factors. Themes related to facilitation of improved care of patients with OUD seen in the ED included a need for on-demand treatment and ED staff training. Conclusions and Relevance: In this qualitative study, patients with OUD reported feeling stigmatized and minimized when accessing care in the ED and identified several opportunities to improve care. The findings suggest that strategies to address stigma, acknowledge and treat pain, and provide ED staff training should be implemented to improve ED care for patients with OUD and enhance access to life-saving treatment.

RESUMO

Background: Restrictive orders and temporary programmatic or ad hoc changes within healthcare and other supportive systems that were implemented in response to the COVID-19 epidemic in Malaysia may have created hindrances to accessing healthcare and/or receiving other supportive services for people who use drugs (PWUDs). Design: A primarily qualitative study has been conducted to evaluate how service providers and recipients were adapting and coping during the initial periods of the COVID-19 response. Settings: The study engaged several healthcare and non-governmental organizations (NGOs) in the peninsular states of Penang, Kelantan, Selangor, and Melaka. Participants: Medical personnel of methadone maintenance treatment (MMT) programs (n = 2) and HIV clinics (n = 3), staff of NGO services (n = 4), and MMT patients (n = 9) were interviewed using a semi-structured format. Results: Interviewed participants reported significant organizational, programmatic, and treatment protocols related changes implemented within the healthcare and support services in addition to nationally imposed Movement Control Orders (MCOs). Changes aimed to reduce patient flow and concentration at the on-site services locations, including less frequent in-person visits, increased use of telemedicine resources, and greater reliance on telecommunication methods to maintain contacts with patients and clients; changes in medication dispensing protocols, including increased take-home doses and relaxed rules for obtaining them, or delivery of medications to patients' homes or locations near their homes were reported by the majority of study participants. No significant rates of COVID-19 infections among PWUDs, including among those with HIV have been reported at the study sites. Conclusions: Although the reported changes presented new challenges for both services providers and recipients and resulted in some degree of initial disruption, generally, all participants reported successful implementation and high levels of compliance with the newly introduced restrictions, regulations, and protocols, resulting in relatively low rates of treatment disruption or discontinuation at the study sites.

RESUMO

BACKGROUND AND AIM: To address the widespread severe problems with opioid use disorder, buprenorphine-naloxone treatment provided by primary care physicians has greatly expanded treatment access; however, treatment is often provided with minimal or no behavioral interventions. Whether or which behavioral interventions are feasible to implement in various settings and improve treatment outcomes has not been established. This study aimed to evaluate two behavioral interventions to improve buprenorphine-naloxone treatment. DESIGN: A 2 × 2 factorial, repeated-measures, open-label, randomized clinical trial. SETTINGS: General medical practice offices in Muar, Malaysia. PARTICIPANTS: Opioid-dependent individuals (n = 234). INTERVENTIONS: Participants were randomly assigned to one of four treatment conditions and received study interventions for 24 weeks: (1) physician management with or without behavioral counseling and (2) physician management with or without abstinence-contingent buprenorphine-naloxone (ACB) take-home doses. MEASUREMENTS: The primary outcomes were proportions of opioid-negative urine tests and HIV risk behaviors [assessed by audio computer-assisted AIDS risk inventory (ACASI-ARI)]. FINDINGS: The rates of opioid-negative urine tests over 24 weeks of treatment were significantly higher with [68.2%, 95% confidence interval (CI) = 65-71] than without behavioral counseling (59.2%, 95% CI = 56-62, P < 0.001) and with (71.0%, 95% CI = 68-74) than without ACB (56.4%, 95% CI = 53-59, P < 0.001); interaction effects between and among behavioral interventions and time were not statistically significant. Scores on ACASI-ARI decreased significantly from baseline across all treatment groups (P < 0.001) and did not differ significantly with or without behavioral counseling (P = 0.099) or with or without ACB (P = 0.339). CONCLUSIONS: Providing opioid-dependent patients in Muar, Malaysia with buprenorphine-naloxone and physician management plus behavioral counseling or abstinence-contingent buprenorphine-naloxone (ACB) resulted in greater reductions of opioid use compared with providing buprenorphine-naloxone and physician management without behavioral counseling or ACB.

RESUMO

OBJECTIVE: Emergency medicine clinicians are uniquely positioned to deliver interventions to enhance linkage to evidence-based treatment for opioid use disorder (OUD) in the acute overdose period, yet little is known about patient perspectives to effectively engage patients immediately following opioid overdose. Our objective was to explore patients' perspectives on substance use treatment, perceived needs, and contextual factors that shape the choice of patients seen in the emergency department (ED) to engage with treatment and other patient support services in the acute post-opioid overdose period. METHODS: We administered a brief quantitative survey and conducted semistructured interviews with 24 adult ED patients receiving care after an acute opioid overdose between June 2016 and August 2017 in an urban, academic ED. We used constant comparison method and thematic analysis to identify themes across four levels of a modified social ecologic model (individual, interpersonal, organizational, and structural). RESULTS: The mean (±SD) age of the sample was 33.5 (±9.33) years; 83% were White and 12% were Black; 67% were male; and 83% were diagnosed with OUD, with a mean (±SD) of 3.25 (±2.64) self-reported lifetime opioid overdoses. Eight themes were identified as influencing participants' consideration of OUD treatment and other services: (1) perceptions about control of drug use, (2) personal experience with substance use treatment, (3) role of interpersonal relationships, (4) provider communication skills, (5) stigma, (6) availability of ED resources, (7) impact of treatment policies, and (8) support for unmet basic needs. CONCLUSIONS: Patients receiving ED care following overdose in our ED are willing to discuss their opioid use and its treatment in the ED and report a variety of unmet needs. This work supports a role for ED-based research evaluating a patient-oriented approach to engage patients after opioid overdose.

RESUMO

BACKGROUND Little is known regarding the sociodemographic and clinical characteristics of emergency department (ED) patients with untreated opioid use disorder (OUD) and the relationship of those characteristics with whether they were seeking a referral to substance use treatment at the time of their ED visit. METHODS Using data collected from 2/2017-1/2019 from participants enrolled in Project ED Health (CTN-0069), we conducted a cross-sectional analysis of patients with untreated moderate to severe OUD presenting to one of four EDs in Baltimore, New York City, Cincinnati, or Seattle. Sociodemographic and clinical correlates, and International Classification of Diseases Tenth Revision (ICD-10) diagnosis codes related to opioid withdrawal, injection-related infection, other substance use, overdose, and OUD of those seeking and not seeking a referral to substance use treatment on presentation were compared using univariate analyses. RESULTS Among 394 study participants, 15.2 % (60/394) came to the ED seeking a referral to substance use treatment. No differences in age, gender, education, health insurance status or housing stability were detected between those seeking and not seeking referral to substance use treatment. Those seeking a referral to substance use treatment were less likely to have urine toxicology testing positive for amphetamine [17 % (10/60) vs 31 % (104/334), p = 0.023] and methamphetamine [23 % (14/60) vs 40 % (132/334), p = 0.017] compared to those not seeking a referral. CONCLUSION Most patients with untreated OUD seen in the EDs were not seeking a referral to substance use treatment. Active identification, treatment initiation, and coding may improve ED efforts to address untreated OUD.

RESUMO

STUDY OBJECTIVE: Concurrent use of amphetamine-type stimulants among individuals with opioid use disorder can exacerbate social and medical harms, including overdose risk. The study evaluated rates of amphetamine-type stimulant use among patients with untreated opioid use disorder presenting at emergency departments in Baltimore, MD; New York, NY; Cincinnati, OH; and Seattle, WA. METHODS: Emergency department (ED) patients with untreated opioid use disorder (N=396) and enrolled between February 2017 and January 2019 in a multisite hybrid type III implementation science study were evaluated for concurrent amphetamine-type stimulant use. Individuals with urine tests positive for methamphetamine, amphetamine, or both were compared with amphetamine-type stimulant-negative patients. RESULTS: Overall, 38% of patients (150/396) were amphetamine-type stimulant positive; none reported receiving prescribed amphetamine or methamphetamine medications. Amphetamine-type stimulant-positive versus -negative patients were younger: mean age was 36 years (SD 10 years) versus 40 years (SD 12 years), 69% (104/150) versus 46% (114/246) were white, 65% (98/150) versus 54% (132/246) were unemployed, 67% (101/150) versus 49 (121/246) had unstable housing, 47% (71/150) versus 25% (61/245) reported an incarceration during 1 year before study admission, 60% (77/128) versus 45% (87/195) were hepatitis C positive, 79% (118/150) versus 47% (115/245) reported drug injection during 1 month before the study admission, and 42% (62/149) versus 29% (70/244) presented to the ED for an injury. Lower proportions of amphetamine-type stimulant-positive patients had cocaine-positive urine test results (33% [50/150] versus 52% [129/246]) and reported seeking treatment for substance use problems as a reason for their ED visit (10% [14/148] versus 19% [46/246]). All comparisons were statistically significant at P<.05 with the false discovery rate correction. CONCLUSION: Amphetamine-type stimulant use among ED patients with untreated opioid use disorder was associated with distinct sociodemographic, social, and health factors. Improved ED-based screening, intervention, and referral protocols for patients with opioid use disorder and amphetamine-type stimulant use are needed.

RESUMO

Background: Kratom has a long history of traditional medicine use in Southeast Asia. Consumption of kratom products has also been reported in the US and other regions of the world. Pain relief is among many self-reported kratom effects but have not been evaluated in controlled human subject research. Methods: Kratom effects on pain tolerance were assessed in a randomized, placebo-controlled, double-blind study. During a 1-day inpatient stay, participants received a randomized sequence of kratom and placebo decoctions matched for taste and appearance. Pain tolerance was measured objectively in a cold pressor task (CPT) as time (seconds) between the pain onset and the hand withdrawal from the ice bath. Health status, vital signs, objective, and subjective indicators of withdrawal symptoms, self-reported data on lifetime kratom use patterns, and assessments of blinding procedures were also evaluated. Results: Twenty-six males with the mean (SD) age 24.3 (3.4) years were enrolled. They reported the mean (SD) 6.1 (3.2) years of daily kratom consumption. Pain tolerance increased significantly 1 hour after kratom ingestion from the mean (SD) 11.2 (6.7) seconds immediately before to 24.9 (39.4) seconds 1 hour after kratom consumption (F(2,53.7)=4.33, p=0.02). Pain tolerance was unchanged after consuming placebo drinks: 15.0 (19.0) seconds immediately before and 12.0 (8.1) seconds 1 hour after consumption of placebo (F(2,52.8)=0.93, p=0.40). No discomfort or signs of withdrawal were reported or observed during 10-20 hours of kratom discontinuation. Conclusions: Kratom decoction demonstrated a substantial and statistically significant increase in pain tolerance. Further rigorous research on kratom pain-relieving properties and a safety profile is needed.

RESUMO

Importance: Treatment of opioid use disorder (OUD) with buprenorphine decreases opioid use and prevents morbidity and mortality. Emergency departments (EDs) are an important setting for buprenorphine initiation for patients with untreated OUD; however, readiness varies among ED clinicians. Objective: To characterize barriers and facilitators of readiness to initiate buprenorphine for the treatment of OUD in the ED and identify opportunities to promote readiness across multiple clinician types. Design, Setting, and Participants: Using data collected from April 1, 2018, to January 11, 2019, this mixed-methods formative evaluation grounded in the Promoting Action on Research Implementation in Health Services framework included 4 geographically diverse academic EDs. Attending physicians (n = 113), residents (n = 107), and advanced practice clinicians (APCs) (n = 48) completed surveys electronically distributed to all ED clinicians (n = 396). A subset of participants (n = 74) also participated in 1 of 11 focus group discussions. Data were analyzed from June 1, 2018, to February 22, 2020. Main Outcomes and Measures: Clinician readiness to initiate buprenorphine and provide referral for ongoing treatment for patients with OUD treated in the ED was assessed using a visual analog scale. Responders (268 of 396 [67.7%]) were dichotomized as less ready (scores 0-6) or most ready (scores 7-10). An ED-adapted Organizational Readiness to Change Assessment (ORCA) and 11 focus groups were used to assess ratings and perspectives on evidence and context-related factors to promote ED-initiated buprenorphine with referral for ongoing treatment, respectively. Results: Among the 268 survey respondents (153 of 260 were men [58.8%], with a mean [SD] of 7.1 [9.8] years since completing formal training), 56 (20.9%) indicated readiness to initiate buprenorphine for ED patients with OUD. Nine of 258 (3.5%) reported Drug Addiction Treatment Act of 2000 training completion. Compared with those who were less ready, clinicians who were most ready to initiate buprenorphine had higher mean scores across all ORCA Evidence subscales (3.50 [95% CI, 3.35-3.65] to 4.33 [95% CI, 4.13-4.53] vs 3.11 [95% CI, 3.03-3.20] to 3.60 [95% CI, 3.49-3.70]; P < .001) and on the Slack Resources of the ORCA Context subscales (3.32 [95% CI, 3.08-3.55] vs 3.0 [95% CI, 2.87-3.12]; P = .02). Barriers to ED-initiated buprenorphine included lack of training and experience in treating OUD with buprenorphine, concerns about ability to link to ongoing care, and competing needs and priorities for ED time and resources. Facilitators to ED-initiated buprenorphine included receiving education and training, development of local departmental protocols, and receiving feedback on patient experiences and gaps in quality of care. Conclusions and Relevance: Only a few ED clinicians had a high level of readiness to initiate buprenorphine; however, many expressed a willingness to learn with sufficient supports. Efforts to promote adoption of ED-initiated buprenorphine will require clinician and system-level changes.

RESUMO

BACKGROUND: The efficacy or tolerability of paliperidone extended release (ER) in the treatment of methamphetamine (METH)-associated psychosis (MAP) is unknown. This study was designed to assess the tolerability and efficacy of paliperidone ER and risperidone for the treatment of MAP in China. METHODS: This 25-day randomized clinical trial involved 120 patients with acute MAP symptoms who were randomized to receive either paliperidone ER or risperidone from baseline to day 25 of an inpatient hospital stay. The primary outcome was changes in the severity of psychosis, which were assessed using the Positive and Negative Syndrome Scale (PANSS) total score changes from baseline to endpoint. RESULTS: Overall, 84% of the patients completed the entire study protocol. The PANSS total score, the Clinical Global Impressions-Severity of Illness scale (CGI-S) score, and a METH craving score assessed by a visual analog scale (VAS) showed statistically significant improvements from baseline for the patients in both groups (p < 0.01). The Simpson-Angus Scale (SAS) and the Barnes Akathisia Rating Scale (BARS) scores increased from baseline during treatment in both groups (p < 0.01); there were statistically significant differences between the treatment groups in the SAS scores (p < 0.01). Measures of hypermyotonia, salivation, and dizziness were significantly higher in the risperidone-treated patients than in the paliperidone ER-treated patients (all p < 0.05). CONCLUSION: Paliperidone ER and risperidone had similar efficacy and were generally tolerable in the treatment of MAP; however, paliperidone ER had a more favorable adverse event profile than risperidone, particularly regarding extrapyramidal and prolactin-increasing effects.

RESUMO

BACKGROUND: Patients with opioid use disorder (OUD) frequently present to the emergency department (ED) after overdose, or seeking treatment for general medical conditions, their addiction, withdrawal symptoms, or complications of injection drug use, such as soft tissue infections. ED-initiated buprenorphine has been shown to be effective in increasing patient engagement in treatment compared with brief intervention with a facilitated referral or referral alone. However, adoption into practice has lagged behind need. To address this implementation challenge, we are evaluating the impact of implementation facilitation (IF) on the adoption of ED-initiated buprenorphine for OUD into practice. METHODS: This protocol describes a study that is being conducted through the National Institute on Drug Abuse's Center for the Clinical Trials Network. A hybrid type III effectiveness-implementation study design is used to evaluate the effectiveness of a standard educational dissemination strategy versus IF on implementation (primary) and effectiveness (secondary) outcomes in four urban, academic EDs. Sites start with a standard 60-min "Grand Rounds" educational intervention describing the prevalence of ED patients with OUD, the evidence for opioid agonist treatment and for innovative interventions with ED-initiated buprenorphine; followed by a 1-year baseline evaluation period. Using a modified stepped wedge design, sites are randomly assigned to the IF intervention which is guided by the Promoting Action on Research Implementation in Health Services (PARiHS) framework to assess evidence, context, and facilitation-related factors impacting the adoption of ED-initiated buprenorphine. During the 6 months of IF through the 1-year IF evaluation period, external facilitators work with local stakeholders to tailor and refine a bundle of activities to meet the site's needs. The primary analyses compare the baseline evaluation period to the IF evaluation period (n = 120 patients with untreated OUD enrolled during each period) on (1) rates of provision of ED-initiated buprenorphine by ED providers with referral for ongoing medication (implementation outcome) and (2) rates of patient engagement in addiction treatment on the 30th day after the ED visit (effectiveness outcome). Finally, we will perform a cost-effectiveness analysis (CEA) to determine if the effectiveness benefits are worth the additional costs. DISCUSSION: Results will generate novel information regarding the impact of IF as a strategy to promote ED-initiated buprenorphine.
