RESUMEN
STUDY OBJECTIVE: We described the experiences and preferences of people with opioid use disorder who access emergency department (ED) services regarding ED care and ED-based interventions. METHODS: Between June and September 2020, we conducted phone or in-person semistructured qualitative interviews with patients recently discharged from 2 urban EDs in Vancouver, BC, Canada, to explore experiences and preferences of ED care and ED-based opioid use disorder interventions. We recruited participants from a cohort of adults with opioid use disorder who were participating in an ED-initiated outreach program. We transcribed audio recordings verbatim. We iteratively developed a thematic coding structure, with interim analyses to assess for thematic saturation. Two team members with lived experience of opioid use provided feedback on content, wording, and analysis throughout the study. RESULTS: We interviewed 19 participants. Participants felt discriminated against for their drug use, which led to poorer perceived health care and downstream ED avoidance. Participants desired to be treated like ED patients who do not use drugs and to be more involved in their ED care. Participants nevertheless felt comfortable discussing their substance use with ED staff and valued continuous ED operating hours. Regarding opioid use disorder treatment, participants supported ED-based buprenorphine/naloxone programs but also suggested additional options (eg, different initiation regimens and settings and other opioid agonist therapies) to facilitate further treatment uptake. CONCLUSION: Based on participant experiences, we recommend addressing potentially stigmatizing practices, increasing patient involvement in their care during ED visits, and increasing access to various opioid use disorder-related treatments and community support.

STUDY OBJECTIVE: Alcohol withdrawal is a common emergency department (ED) presentation. Although benzodiazepines reduce symptoms of withdrawal, there is little ED-based evidence to assist clinicians in selecting appropriate pharmacotherapy. We compare lorazepam with diazepam for the management of alcohol withdrawal to assess 1-week ED and hospital-related outcomes. METHODS: From January 1, 2015, to December 31, 2018, at 3 urban EDs in Vancouver, Canada, we studied patients with a discharge diagnosis of alcohol withdrawal. We excluded individuals presenting with a seizure or an acute concurrent illness. We performed a structured chart review to ascertain demographics, ED treatments, and outcomes. Patients were stratified according to initial management with lorazepam versus diazepam. The primary outcome was hospital admission, and secondary outcomes included in-ED seizures and 1-week return visits for discharged patients. RESULTS: Of 1,055 patients who presented with acute alcohol withdrawal, 898 were treated with benzodiazepines. Median age was 47 years (interquartile range 37 to 56 years) and 73% were men. Baseline characteristics were similar in the 2 groups. Overall, 69 of 394 patients (17.5%) receiving lorazepam were admitted to the hospital compared with 94 of 504 patients receiving diazepam (18.7%), a difference of 1.2% (95% confidence interval -4.2% to 6.3%). Seven patients (0.7%; 95% confidence interval 0.3% to 1.4%) had an in-ED seizure, but all seizures occurred before receipt of benzodiazepines. Among patients discharged home, 1-week return visits occurred for 78 of 325 (24.0%) who received lorazepam and 94 of 410 (23.2%) who received diazepam, a difference of 0.8% (95% confidence interval -5.3% to 7.1%). CONCLUSION: In our sample of ED patients with acute alcohol withdrawal, patients receiving lorazepam had an admission rate similar to that of those receiving diazepam. The few in-ED seizures occurred before medication administration. For discharged patients, the 1-week ED return visit rate of nearly 25% could warrant enhanced follow-up and community support.

BACKGROUND AND OBJECTIVES: Although buprenorphine/naloxone is widely recognized as first-line therapy for opioid use disorder, the requirement for moderate withdrawal prior to initiation in efforts to avoid precipitated withdrawal can be a barrier to its initiation. METHODS: We present a case utilizing transdermal fentanyl as a bridging treatment to eliminate withdrawal during the transition from methadone to buprenorphine/naloxone in a patient who had ongoing significant intravenous heroin use while on methadone. RESULTS: Patient was successfully transitioned from methadone to buprenorphine/naloxone without a period of withdrawal utilizing transdermal fentanyl as a bridge in an inpatient setting. DISCUSSION AND CONCLUSIONS: Our experience indicates a transdermal depot of fentanyl allows for slow release and elimination while buprenorphine doses are introduced during an induction without presence of withdrawal, as quantified by serial clinical opiate withdrawal score. SCIENTIFIC SIGNIFICANCE: This case report highlights ways to minimize barriers to induction of first-line opioid substitution therapy, buprenorphine/naloxone, by eliminating withdrawal during induction phase utilizing a fentanyl bridge within the limitations of a transdermal fentanyl bridge in an inpatient setting.

BACKGROUND: People with opioid use disorder (OUD) are high-risk for short-term mortality and morbidity. Emergency department (ED) interventions can reduce those risks, but benefits wane without ongoing community follow-up. OBJECTIVE: To evaluate an ED-based intensive community outreach program. METHODS: At two urban EDs between October 2019 and March 2020, we enrolled patients with OUD not currently on opioid agonist therapy (OAT) in a prospective cohort study evaluating a one-year intensive community outreach program, which provided ongoing addictions care, housing resources, and community support. We surveyed patients at intake and at scheduled outreach encounters at one, two, six, and twelve months. Follow-up surveys assessed OAT uptake, addictions care engagement, housing status, quality of life scores, illicit opioid use, and outreach helpfulness. We used descriptive statistics for each period and conducted sensitivity and subgroup analyses to account for missing data. RESULTS: Of 84 baseline participants, 29% were female and 32% were housed, with a median age of 33. Sixty participants (71%) completed at least one follow-up survey. Survey completion rates were 37%, 38%, 39%, and 40% respectively at one, two, six, and twelve months. Participants had a median of three outreach encounters. Among respondents, OAT was 0% at enrolment and ranged from 38% to 56% at follow-up; addictions care engagement was 22% at enrolment and ranged from 65% to 81% during follow-up; and housing was 40% at enrolment and ranged from 48% to 59% during follow-up. Improvements from baseline to follow-up occurred for all time periods. OAT and engagement in care benefits were maintained in sensitivity and subgroup analyses. Respondents rated the outreach program as helpful at all time periods, CONCLUSION: An ED-initiated intensive outreach program for patients with OUD not yet on OAT was associated with a persistent increase in OAT use and engagement in care, as well as housing.

The fourth Society for Academic Emergency Medicine (SAEM) Guidelines for Reasonable and Appropriate Care in the Emergency Department (GRACE-4) is on the topic of the emergency department (ED) management of nonopioid use disorders and focuses on alcohol withdrawal syndrome (AWS), alcohol use disorder (AUD), and cannabinoid hyperemesis syndrome (CHS). The SAEM GRACE-4 Writing Team, composed of emergency physicians and experts in addiction medicine and patients with lived experience, applied the Grading of Recommendations Assessment Development and Evaluation (GRADE) approach to assess the certainty of evidence and strength of recommendations regarding six priority questions for adult ED patients with AWS, AUD, and CHS. The SAEM GRACE-4 Writing Team reached the following recommendations: (1) in adult ED patients (over the age of 18) with moderate to severe AWS who are being admitted to hospital, we suggest using phenobarbital in addition to benzodiazepines compared to using benzodiazepines alone [low to very low certainty of evidence]; (2) in adult ED patients (over the age of 18) with AUD who desire alcohol cessation, we suggest a prescription for one anticraving medication [very low certainty of evidence]; (2a) in adult ED patients (over the age of 18) with AUD, we suggest naltrexone (compared to no prescription) to prevent return to heavy drinking [low certainty of evidence]; (2b) in adult ED patients (over the age of 18) with AUD and contraindications to naltrexone, we suggest acamprosate (compared to no prescription) to prevent return to heavy drinking and/or to reduce heavy drinking [low certainty of evidence]; (2c) in adult ED patients (over the age of 18) with AUD, we suggest gabapentin (compared to no prescription) for the management of AUD to reduce heavy drinking days and improve alcohol withdrawal symptoms [very low certainty of evidence]; (3a) in adult ED patients (over the age of 18) presenting to the ED with CHS we suggest the use of haloperidol or droperidol (in addition to usual care/serotonin antagonists, e.g., ondansetron) to help with symptom management [very low certainty of evidence]; and (3b) in adult ED patients (over the age of 18) presenting to the ED with CHS, we also suggest offering the use of topical capsaicin (in addition to usual care/serotonin antagonists, e.g., ondansetron) to help with symptom management [very low certainty of evidence].

BACKGROUND: Approximately one-quarter of emergency department (ED) visits for alcohol withdrawal result in unscheduled 1-week ED return visits, but it is unclear what patient and clinical factors may impact this outcome METHODS: From January 1, 2015, to December 31, 2018, at three urban EDs in Vancouver, Canada, we studied patients who were discharged with a primary or secondary diagnosis of alcohol withdrawal. We performed a structured chart review to ascertain patient characteristics, ED treatments, and the outcome of an ED return within 1 week of discharge. We used univariable and multivariable Bayesian binomial regression to identify characteristics associated with being in the upper quartile of 1-week ED revisits. RESULTS: We collected 935 ED visits among 593 unique patients. Median age was 45 years (interquartile range 34 to 55 years) and 71% were male. The risk of a 1-week ED revisit was 15.0% (IQR 12.3; 19.5%). After adjustment, factors independently associated with a high risk for return included any prior ED visit within 30 days, no fixed address, initial blood alcohol level > 45 mmol/L, and initial Clinical Institute Withdrawal Assessment-alcohol revised score > 23. These factors explained 41% of the overall variance in revisits. CONCLUSION: Among discharged ED patients with alcohol withdrawal, we describe high-risk patient characteristics associated with 1-week ED revisits, and these findings may assist clinicians to facilitate appropriate discharge planning with access to integrated follow-up support.
RéSUMé: CONTEXTE: Environ un quart des visites aux urgences pour sevrage alcoolique se traduit par un retour non programmé aux urgences pendant une semaine, mais les facteurs cliniques et relatifs aux patients qui peuvent avoir une incidence sur ce résultat ne sont pas clairs. MéTHODES: Du 1er janvier 2015 au 31 décembre 2018, dans trois urgences urbaines de Vancouver, au Canada, nous avons étudié les patients qui sont sortis avec un diagnostic primaire ou secondaire de sevrage alcoolique. Nous avons procédé à une analyse structurée des dossiers afin de déterminer les caractéristiques des patients, les traitements aux urgences et l'issue d'un retour aux urgences dans la semaine suivant la sortie. Nous avons utilisé une régression binomiale bayésienne univariable et multivariable pour identifier les caractéristiques associées au fait d'être dans le quartile supérieur des visites aux urgences à une semaine. RéSULTATS: Nous avons recueilli 935 visites aux urgences parmi 593 patients uniques. L'âge médian était de 45 ans (intervalle interquartile de 34 à 55 ans) et 71 % étaient des hommes. Le risque d'une nouvelle visite aux urgences à une semaine était de 15,0% (IQR 12,3 ; 19,5%). Après ajustement, les facteurs indépendamment associés à un risque élevé de retour comprenaient toute visite antérieure à l'urgence dans les 30 jours, aucune adresse fixe, le taux d'alcoolémie initial > 45 mmol/L, et l'évaluation initiale du sevrage de l'Institut clinique cote d'alcoolémie révisée > 23. Ces facteurs expliquaient 41 % de la variance globale des visites. CONCLUSIONS: Parmi les patients sortants des urgences en sevrage alcoolique, nous décrivons les caractéristiques des patients à haut risque associés à la réadmission aux urgences après une semaine de sevrage alcoolique. Ces résultats peuvent aider les cliniciens à planifier de manière appropriée la sortie de l'hôpital et à accéder à un suivi intégré.

OBJECTIVES: Many emergency department (ED) patients with opioid use disorder are candidates for home buprenorphine/naloxone initiation with to-go packs. We studied patient opinions and acceptance of buprenorphine/naloxone to-go packs, and factors associated with their acceptance. METHODS: We identified patients at two urban EDs in British Columbia who met opioid use disorder criteria, were not presently on opioid agonist therapy and not in active withdrawal. We offered patients buprenorphine/naloxone to-go as standard of care and then administered a survey to record buprenorphine/naloxone to-go acceptance, the primary outcome. Survey domains included current substance use, prior experience with opioid agonist therapy, and buprenorphine/naloxone related opinions. Patient factors were examined for association with buprenorphine/naloxone to-go acceptance. RESULTS: Of the 89 patients enrolled, median age was 33 years, 27% were female, 67.4% had previously taken buprenorphine/naloxone, and 19.1% had never taken opioid agonist therapy. Overall, 78.7% believed that EDs should dispense buprenorphine/naloxone to-go packs. Thirty-eight (42.7%) patients accepted buprenorphine/naloxone to-go. Buprenorphine/naloxone to-go acceptance was associated with lack of prior opioid agonist therapy, less than 10 years of opioid use and no injection drug use. Reasons to accept included initiating treatment while in withdrawal; reasons to reject included prior unsatisfactory buprenorphine/naloxone experience and interest in other treatments. CONCLUSION: Although less than half of our study population accepted buprenorphine/naloxone to-go when offered, most thought this intervention was beneficial. In isolation, ED buprenorphine/naloxone to-go will not meet the needs of all patients with opioid use disorder. Clinicians and policy makers should consider buprenorphine/naloxone to-go as a low-barrier option for opioid use disorder treatment from the ED when integrated with robust addiction care services.
RéSUMé: OBJECTIFS: De nombreux patients des services d'urgence (SU) atteints d'un trouble lié à la consommation d'opioïdes sont des candidats à l'initiation à la buprénorphine/naloxone à domicile avec des trousses à emporter. Nous avons étudié les opinions des patients et l'acceptation des paquets de buprénorphine/naloxone à emporter, ainsi que les facteurs associés à leur acceptation. MéTHODES: Nous avons identifié des patients à deux urgences urbaines de la Colombie-Britannique qui répondaient aux critères relatifs aux troubles liés à l'utilisation d'opioïdes, qui ne suivaient pas actuellement un traitement aux agonistes des opioïdes et qui n'étaient pas en sevrage actif. Nous avons offert aux patients la buprénorphine/naloxone à emporter comme norme de soins, puis nous avons administré une enquête pour enregistrer l'acceptation de la buprénorphine/naloxone à emporter, le critère de jugement principal. Les domaines d'enquête comprenaient la consommation actuelle de substances, l'expérience antérieure avec le traitement aux agonistes opioïdes et les opinions liées à la buprénorphine/naloxone. Les facteurs du patient ont été examinés pour déterminer l'association avec l'acceptation de la buprénorphine/naloxone à emporter. RéSULTATS: Sur 89 patients inscrits, l'âge médian était de 33 ans, 27,0% étaient des femmes, 67,4% avaient déjà pris de la buprénorphine/naloxone et 19,1% n'avaient jamais pris de traitement aux agonistes opioïdes. Dans l'ensemble, 78,7% des répondants étaient d'avis que les SU devraient distribuer des paquets de buprénorphine/naloxone à emporter. Trente-huit (42,7%) patients ont accepté la buprénorphine/naloxone à emporter. L'acceptation de la buprénorphine/naloxone à emporter était associée à l'absence de traitement antérieur par agonistes opioïdes, à moins de 10 ans d'utilisation d'opioïdes et à l'absence de consommation de drogues injectables. Les raisons d'accepter comprenaient le fait de commencer un traitement pendant le sevrage; les raisons de rejeter comprenaient une expérience antérieure insatisfaisante de buprénorphine/naloxone et un intérêt pour d'autres traitements. CONCLUSION: Bien que moins de la moitié de notre population à l'étude ait accepté la buprénorphine/naloxone à emporter lorsqu'elle lui était offerte, la plupart ont pensé que cette intervention était bénéfique. Isolément, la buprénorphine/naloxone à emporter à l'urgence ne répondra pas aux besoins de tous les patients atteints de troubles liés à l'utilisation d'opioïdes. Les cliniciens et les décideurs devraient considérer la buprénorphine/naloxone à emporter comme une option à faible barrière pour le traitement des troubles liés à la consommation d'opioïdes par l'urgence lorsqu'elle est intégrée à de solides services de soins de la toxicomanie.

AIM: To capture pandemic experiences of people with opioid use disorder (OUD) to better inform the programs that serve them. DESIGN: We designed, conducted, and analyzed semi-structured qualitative interviews using grounded theory. We conducted interviews until theme saturation was reached and we iteratively developed a codebook of emerging themes. Individuals with lived experience of substance use provided feedback at all steps of the study. SETTING: We conducted phone or in-person interviews in compliance with physical distancing and public health regulations in outdoor Vancouver parks or well-ventilated indoor spaces between June to September 2020. PARTICIPANTS: Using purposive sampling, we recruited participants (n = 19) who were individuals with OUD enrolled in an intensive community outreach program, had visited one of two emergency departments, were over 18, lived within catchment, and were not already receiving opioid agonist therapy. MEASUREMENTS: We audio-recorded interviews, which were later transcribed verbatim and checked for accuracy while removing all identifiers. Interviews explored participants' knowledge of COVID-19 and related safety measures, changes to drug use and healthcare services, and community impacts of COVID-19. RESULTS: One third of participants were women, approximately two thirds had stable housing, and ages ranged between 23 and 59 years old. Participants were knowledgeable on COVID-19 public health measures. Some participants noted that fear decreased social connection and reluctance to help reverse overdoses; others expressed pride in community cohesion during crisis. Several participants mentioned decreased access to housing, harm reduction, and medical care services. Several participants reported using drugs alone more frequently, consuming different or fewer drugs because of supply shortages, or using more drugs to replace lost activities. CONCLUSION: COVID-19 had profound effects on the social lives, access to services, and risk-taking behaviour of people with opioid use disorder. Pandemic public health measures must include risk mitigation strategies to maintain access to critical opioid-related services.

Deaths due to opioid overdose have reached unprecedented levels in Canada; over 12,800 opioid-related deaths occurred between January 2016 and March 2019, and overdose death rates increased by approximately 50% from 2016 to 2018.1 In 2016, Health Canada declared the opioid epidemic a national public health crisis,2 and life expectancy increases have halted in Canada for the first time in decades.3 Children are not exempt from this crisis, and the Chief Public Health Officer of Canada has recently prioritized the prevention of problematic substance use among Canadian youth.4.

OBJECTIVES: With regionalized trauma care, medical transport times can be prolonged, requiring paramedics to manage patient care and symptoms. Our objective was to evaluate pain management during air transport of trauma patients. METHODS: We conducted a 12-month review of electronic paramedic records from a provincial critical care transport agency. Patients were included if they were ≥18 years old and underwent air transport to a trauma centre, and excluded if they were Glasgow Coma Scale score <14, intubated, or accompanied by a physician or nurse. Demographics, injury description, and transportation parameters were recorded. Outcomes included pain assessment via 11-point numerical rating scale, patterns of analgesia administration, and analgesia-related adverse events. Results were reported as mean ± standard deviation, [range], (percentage). RESULTS: We included 372 patients: 47.0 years old; 262 males; 361 blunt injuries. Transport duration was 82.4 ± 46.3 minutes. In 232 (62.4%) patients who received analgesia, baseline numerical rating scale was 5.9 ± 2.5. Fentanyl was most commonly administered at 44.3 [25-60] mcg. Numerical rating scale after first analgesia dose decreased by 1.1 [-2-7]. Thereafter, 171 (73.7%) patients received 2.4 [1-18] additional doses. While 44 (23.4%) patients had no change in numerical rating scale after first analgesia dose, subsequent doses resulted in no change in numerical rating scale in over 65% of patients. There were 43 adverse events recorded, with nausea the most commonly reported (39.5%). CONCLUSIONS: Initial and subsequent dose(s) of analgesic had minimal effect on pain as assessed via numerical rating scale, likely due in part to inadequate dosing. Future research is required to determine and address the barriers to proper analgesia.
OBJECTIF: Compte tenu de la régionalisation des soins en traumatologie, la durée des transports pour raison médicale peut être prolongée, ce qui oblige les ambulanciers paramédicaux à traiter les symptômes et à donner des soins. L'étude visait donc à évaluer le soulagement de la douleur durant le transport aérien des polytraumatisés. MÉTHODE: L'étude consistait en un examen de dossiers électroniques d'ambulanciers paramédicaux, provenant d'une agence provinciale de transport de blessés en phase critique, sur une période de 12 mois. Les critères d'inclusion comprenaient un âge ≥ 18 ans et le transport aérien vers un centre de traumatologie; et les critères d'exclusion, un score < 14 sur l'échelle de Glasgow, l'intubation ou l'accompagnement d'un médecin ou d'une infirmière. La collecte d'éléments factuels se composait de données démographiques, de renseignements sur les blessures et de paramètres relatifs au transport. Les résultats étudiés comprenaient l'évaluation de la douleur sur une échelle numérique de 11 points, les modes d'administration des analgésiques et les événements indésirables liés à l'analgésie. Les résultats sont exprimés sous forme de moyenne ± l'écart type [fourchette], (pourcentage). RÉSULTATS: Ont été retenus dans l'étude 372 patients : âge : 47,0 ans; hommes : 262; contusions : 361. La durée de transport était de 82,4 ± 46,3 minutes. Parmi les 232 patients (62,4%) qui ont reçu des analgésiques, la douleur au départ s'élevait à 5,9 ± 2,5 sur l'échelle numérique. Le médicament le plus souvent administré était le fentanyl, à raison de 44,3 µg [2560]. Une diminution de l'intensité de la douleur de 1,1 [-27] sur l'échelle numérique a été enregistrée après la première dose d'analgésique; par la suite, 171 patients (73,7%) ont reçu 2,4 doses additionnelles [118]. De leur côté, 44 patients (23,4%) n'ont noté aucun changement sur l'échelle numérique après la première dose d'analgésique, et les doses suivantes n'ont rien changé à l'évaluation de la douleur chez plus de 65% des patients. Enfin, 43 événements indésirables ont été enregistrés, dont le plus fréquent était les nausées (39,5%). CONCLUSIONS: Les doses initiales et subséquentes d'analgésiques ont eu peu d'effets sur le soulagement de la douleur, selon l'évaluation faite sur l'échelle numérique, probablement en raison d'un dosage inadéquat, du moins en partie. Aussi faudrait-il mener des études sur les obstacles à l'administration d'une analgésie appropriée et sur la manière de les vaincre.
