"They were very very nice but just not very good": The interplay between resident-supervisor relationships and assessment in the emergency setting.

Purpose: Clinical supervisors hesitate to report learner weaknesses, a widely documented phenomenon referred to as "failure to fail." They also struggle to discuss weaknesses with learners themselves. Their reluctance to report and discuss learner weaknesses threatens the validity of assessment-of-learning decisions and the effectiveness of assessment for learning. Personal and interpersonal factors have been found to act as barriers to reporting learners' difficulties, but the precise role of the resident-supervisor relationship remains underexplored, specifically in the emergency setting. This study aims to better understand if and how factors related to the resident-supervisor relationship are involved in assessment of and for learning in the emergency setting. Methods: We conducted a qualitative study, using semistructured interviews of 15 clinical supervisors in emergency medicine departments affiliated with our institution. Transcripts were independently coded by three members of the team using an iterative mixed deductive-inductive thematic analysis approach. The team then synthesized the coding and discussed analysis following guidelines for thematic analysis. Results: Participating emergency medicine supervisors valued resident-supervisor relationships built on collaboration and trust and believed that such relationships support learning. They described how these relationships influenced assessment of and for learning and how in turn assessment influenced the relationship. Almost all profiles of resident-supervisor relationships in our study could hinder the disclosing of resident weaknesses, through a variety of mechanisms. To protect residents and themselves from the discomfort of disclosing weaknesses and to avoid deteriorating the resident-supervisor relationship, many downplayed or even masked residents' difficulties. Supervisors who described themselves as able to provide negative assessment of and for learning often adopted a more distant or professional stance. Conclusions: This study contributes to a growing literature on failure to fail by confirming the critical impact that the resident-supervisor relationship has on the willingness and ability of emergency medicine supervisors to play their part as assessors.

The influence of the simulation environment on teamwork and cognitive load in novice trauma professionals at the emergency department: Piloting a randomized controlled trial.

INTRODUCTION: This pilot study aimed to test the feasibility of conducting a randomized controlled trial to examine how simulation environments (in situ versus laboratory) influence teamwork skills development and cognitive load among novice healthcare trauma professionals in the emergency department. METHOD: Twenty-four novice trauma professionals (nurses, medical residents, respiratory therapists) were assigned to in situ or laboratory simulations. They participated in two 15-minute simulations separated by a 45-minute debriefing on teamwork. After each simulation, they completed validated teamwork and cognitive load questionnaires. All simulations were video recorded to assess teamwork performance by trained external observers. Feasibility measures (e.g., recruitment rate, randomization procedure and intervention implementation) were recorded. Mixed ANOVAs were used to calculate effect sizes. RESULTS: Regarding feasibility, several difficulties were encountered, such as a low recruitment rate and the inability to perform randomization. Outcome results suggest that the simulation environment does not affect novice trauma professionals' teamwork performance and cognitive load (small effect sizes), but a large effect size was observed for perceived learning. CONCLUSION: This study highlights several barriers to conducting a randomized study in the context of interprofessional simulation-based education in the emergency department. Suggestions are made to guide future research in the field.

Clinical outcomes following out-of-hospital cardiac arrest: The minute-by-minute impact of bystander cardiopulmonary resuscitation.

AIMS: The time-dependent prognostic role of bystander cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) patients has not been described with great precision, especially for neurologic outcomes. Our objective was to assess the association between bystander CPR, emergency medical service (EMS) response time, and OHCA patients' outcomes. METHODS: This cohort study used the Resuscitation Outcomes Consortium Cardiac Epidemiologic Registries. Bystander-witnessed adult OHCA treated by EMS were included. The primary outcome was survival to hospital discharge and secondary outcome was survival with a good neurologic outcome (modified Rankin scale 0-2). Multivariable logistic regression models were used to assess the associations and interactions between bystander CPR, EMS response time and clinical outcomes. RESULTS: Out of 229,637 patients, 41,012 were included (18,867 [46.0%] without bystander CPR and 22,145 [54.0%] with bystander CPR). Bystander CPR was independently associated with higher survival (adjusted odds ratio [AOR] = 1.70 [95%CI 1.61-1.80]) and survival with a good neurologic outcome (AOR = 1.87 [95%CI 1.70-2.06]), while longer EMS response times were independently associated with lower survival to hospital discharge (each additional minute of EMS response time: AOR = 0.92 [95%CI 0.91-0.93], p < 0.001) and lower survival with a good neurologic outcome (AOR = 0.88 [95%CI 0.86-0.89], p < 0.001). There was no interaction between bystander CPR and EMS response time's association with survival (p = 0.12) and neurologic outcomes (p = 0.65). CONCLUSIONS: Although bystander CPR is associated with an immediate increase in odds of survival and of good neurologic outcome for OHCA patients, it does not influence the negative association between longer EMS response time and survival and good neurologic outcome.

Association of Initial Pulseless Electrical Activity Heart Rate and Clinical Outcomes following Adult Non-Traumatic Out-of-Hospital Cardiac Arrest.

OBJECTIVE: Studies evaluating the prognostic value of the pulseless electrical activity (PEA) heart rate in out-of-hospital cardiac arrest (OHCA) patients have reported conflicting results. The objective of this study was to evaluate the association between the initial PEA heart rate and favorable clinical outcomes for OHCA patients. METHODS: The present post-hoc cohort study used the Resuscitation Outcomes Consortium Cardiac Epidemiologic Registry Version 3, which included OHCA patients in seven US and three Canadian sites from April 2011 to June 2015. The primary outcome was survival to hospital discharge and the secondary outcome was survival with a good functional outcome. For the primary analysis, the patients were separated into eight groups according to their first rhythms and PEA heart rates: (1) initial PEA heart rate of 1-20 beats per minute (bpm); (2) 21-40 bpm; (3) 41-60 bpm; (4) 61-80 bpm; (5) 81-100 bpm; (6) 101-120 bpm; (7) over 120 bpm; (8) initial shockable rhythm (reference category). Multivariable logistic regression models were used to assess the associations of interest. RESULTS: We identified 17,675 patients (PEA: 7,089 [40.1%]; initial shockable rhythm: 10,797 [59.9%]). Patients with initial PEA electrical frequencies ≤100 bpm were less likely to survive to hospital discharge than patients with initial shockable rhythms (1-20 bpm: adjusted odds ratio [AOR] = 0.15 [95%CI 0.11-0.21]; 21-40 bpm: AOR = 0.21 [0.18-0.25]; 41-60 bpm: AOR = 0.30 [0.25-0.36]; 61-80 bpm: AOR = 0.37 [0.28-0.49]; 81-100 bpm: AOR = 0.55 [0.41-0.65]). However, there were no statistical outcome differences between PEA patients with initial electrical frequencies of >100 bpm and patients with initial shockable rhythms (101-120 bpm: AOR = 0.65 [95%CI 0.42-1.01]; >120 bpm: AOR = 0.72 [95%CI 0.37-1.39]). Similar results were observed for survival with good functional outcomes (101-120 bpm: AOR = 0.60 [95%CI 0.31-1.15]; >120 bpm: AOR = 1.08 [95%CI 0.50-2.28]). CONCLUSIONS: We observed a good association between higher initial PEA electrical frequency and favorable clinical outcomes for OHCA patients. As there is no significant difference in outcomes between patients with initial PEA heart rates of more than 100 bpm and those with initial shockable rhythms, we can hypothesize that these patients could be considered in the same prognostic category.

Accuracy of a self-report prescription opioid use diary for patients discharge from the emergency department with acute pain: a multicentre prospective cohort study.

OBJECTIVES: Self-reported approaches that assess opioid usage can be subject to social desirability and recall biases that may underestimate actual pill consumption. Our objective was to determine the accuracy of patient self-reported opioid consumption using a 14-day daily paper or electronic diary. DESIGN: Prospective cohort study. SETTING: Multicentre study conducted in four Québec (Canada) emergency departments (ED): three university-affiliated centres, two of them Level I trauma centres and one urban community hospital. PARTICIPANTS: ED patients aged ≥18 years with acute pain (≤2 weeks) who were discharged with an opioid prescription. Patients completed a 14-day daily diary (paper or electronic) assessing the quantity of opioids consumed. On diary completion, a random sample from the main cohort was selected for a follow-up visit to the hospital or a virtual video visit where they had to show and count the remaining pills. Patients were blinded to the main objective of the follow-up visit. OUTCOMES: Quantity of opioid pills consumed during the 2-week follow-up period self-reported in the 14-day diary (paper or electronic) and calculated from remaining pills counted during the follow-up visit. Intraclass correlation coefficient (ICC) and Bland-Altman plots were used to assess accuracy. RESULTS: A total of 166 participants completed the 14-day diary as well as the in-person or virtual visit; 49.4% were women and median age was 47 years (IQR=21). The self-reported consumed quantity of opioid in the 14-day diary and the one calculated from counting remaining opioid pills during the follow-up visit were very similar (ICC=0.992; 95% CI: 0.989 to 0.994). The mean difference between both measures from Bland-Altman analysis was almost zero (0.048 pills; 95% CI: -3.77 to 3.87). CONCLUSION: Self-reported prescription opioid use in a 14-day diary is an accurate assessment of the quantity of opioids consumed in ED discharged patients. TRIAL REGISTRATION NUMBER: NCT03953534.

Accuracy of the Initial Rhythm to Predict a Short No-Flow Time in Out-of-Hospital Cardiac Arrest.

OBJECTIVES: The no-flow time (NFT) can help establish prognosis in out-of-hospital cardiac arrest (OHCA) patients. It is often used as a selection criterion for extracorporeal resuscitation. In patients with an unwitnessed OHCA for whom the NFT is unknown, the initial rhythm has been proposed to identify those more likely to have had a short NFT. Our objective was to determine the predictive accuracy of an initial shockable rhythm for an NFT of 5 minutes or less (NFT ≤ 5). DESIGN: Retrospective analysis of prospectively collected data. SETTING: Prehospital OHCA in eight U.S. and three Canadian sites. PATIENTS: A total of 28,139 adult patients with a witnessed nontraumatic OHCA were included, of whom 11,228 (39.9%) experienced an emergency medical service-witnessed OHCA (NFT = 0), 695 (2.7%) had a bystander-witnessed OHCA, and an NFT less than or equal to 5, and 16,216 (57.6%) with a bystander-witnessed OHCA and an NFT greater than 5. INTERVENTIONS: Sensitivity, specificity, and likelihood ratios of an initial shockable rhythm to identify patients with an NFT less than or equal to 5 minutes. MEASUREMENTS AND MAIN RESULTS: The sensitivity of an initial shockable rhythm to identify patients with an NFT less than or equal to 5 was poor (25% [95% CI, 25-26]), but specificity was moderate (70% [95% CI, 69-71]). The positive and likelihood ratios were inverted (negative accuracy) (positive likelihood ratio, 0.76 [95% CI, 0.74-0.79]; negative likelihood ratio, 1.12 [95% CI, 1.10-1.12]). Including only patients with a bystander-witnessed OHCA improved the sensitivity to 48% (95% CI, 45-52), the positive likelihood ratio to 1.45 (95% CI, 1.33-1.58), and the negative likelihood ratio to 0.77 (95% CI, 0.72-0.83), while slightly lowering the specificity to 67% (95% CI, 66-67). CONCLUSIONS: Our analysis demonstrated that the presence of a shockable rhythm at the time of initial assessment was poorly sensitive and only moderately specific for OHCA patients with a short NFT. The initial rhythm, therefore, should not be used as a surrogate for NFT in clinical decision-making.

The responsibility to care: lessons learned from emergency department workers' perspectives during the first wave of the COVID-19 pandemic in Canada.

BACKGROUND: This study's objective was to examine emergency department (ED) workers' perspectives during the Canadian COVID-19 first wave. METHODS: This qualitative study included workers from nine Canadian EDs who participated in 3 monthly video focus groups between April and July 2020 to explore (1) personal/professional experiences, (2) patient care and ED work, (3) relationships with teams, institutions and governing bodies. Framework analysis informed data collection and analysis. RESULTS: Thirty-six focus groups and 15 interviews were conducted with 53 participants (including 24 physicians, 16 nurses). Median age was 37.5 years, 51% were female, 79% had more than 5 years' experience. Three main themes emerged. (1) Early in this pandemic, participants felt a responsibility to provide care to patients and solidarity toward their ED colleagues and team, while balancing many risks with their personal protection. (2) ED teams wanted to be engaged in decision-making, based on the best available scientific knowledge. Institutional decisions and clinical guidelines needed to be adapted to the specificity of each ED environment. (3) Working during the pandemic created new sources of moral distress and fatigue, including difficult clinical practices, distance with patients and families, frequent changes in information and added sources of fatigue. Although participants quickly adapted to a "new normal", they were concerned about long-term burnout. Participants who experienced high numbers of patient deaths felt especially unprepared. INTERPRETATION: ED workers believe they have a responsibility to provide care through a pandemic. Trust in leadership is supported by managers who are present and responsive, transparent in their communication, and involve ED staff in the development and practice of policies and procedures. Such practices will help protect from burnout and ensure the workforce's long-term sustainability.

RéSUMé: CONTEXTE: Cette étude avait pour objectif d'examiner le point de vue des travailleurs des services d'urgence pendant la première vague de la COVID-19 au Canada. MéTHODES: Cette étude qualitative a inclus des travailleurs de neuf services d'urgence canadiens qui ont participé à 3 groupes de discussion monsuels par visioconférence entre avril et juillet 2020, pour explorer: (1) leurs expériences personnelles/professionnelles, (2) les soins aux patients et le travail au service d'urgence, (3) leurs relations avec les équipes, les institutions et instances dirigeantes. Le "framework analysis" a guidé le receuil et l'analyse des données. RéSULTATS: Trente-six groupes de discussion et 15 entretiens individuels ont été menés avec 53 participants (dont 24 médecins et 16 infirmières). L'âge médian était de 37,5 ans, 51% étaient des femmes, 79% avaient plus de 5 ans d'expérience. Trois thèmes principaux sont ressortis. (1) Au début de cette pandémie, les participants se sont sentis responsables de prodiguer des soins aux patients et solidaires envers leurs collègues et leurs équipes des urgences, tout en cherchant à équilibrer la gestion de nombreux risques et leur protection personnelle. (2) Les équipes des services d'urgence souhaitaient participer aux prises de décision, informées par les meilleures connaissances scientifiques disponibles. Les décisions institutionnelles et les lignes directrices cliniques doivent être adaptées à la spécificité de chaque salle d'urgence. (3) Travailler pendant la pandémie a créé de nouvelles sources de détresse morale et de fatigue, notamment des pratiques cliniques difficiles, la distance avec les patients et les familles, les changements fréquents d'information. Bien que les participants se soient rapidement adaptés à une « nouvelle normalité¼, ils étaient préoccupés par l'épuisement professionnel des travailleurs au long terme. Les participants qui ont vécu un nombre élevé de décès de patients à l'urgence se sentaient particulièrement mal préparés. INTERPRéTATION: Les travailleurs des services d'urgence estiment qu'ils ont la responsabilité de fournir des soins en cas de pandémie. Un sentiment de confiance dans les décideurs peut être soutenu par des gestionnaires qui sont présents et réactifs, transparents dans leur communication, et qui impliquent le personnel des services d'urgence dans le développement des politiques et procédures cliniques. De telles pratiques aideront à protéger contre l'épuisement professionnel pour garantir le bien-être des travailleurs d'urgence.

Electrical rhythm degeneration in adults with out-of-hospital cardiac arrest according to the no-flow and bystander low-flow time.

AIMS: For out-of-hospital cardiac arrest (OHCA) patients, the influence of the delay before the initiation of resuscitation, termed the no-flow time (NFT), and duration of bystander-only resuscitation low-flow time (BLFT) on the type of electrical rhythm observed has not been well described. The objective of this study is to determine the relationship between NFT, BLFT and the likelihood of a shockable rhythm over time. METHODS: Using a North American prospective registry (2005-2015; mostly urban settings), we selected adult (18 years and over) patients who experienced a witnessed OHCA from a suspected cardiac etiology. Patients with an emergency medical services witnessed OHCA were only included in sensitivity analyses. The association between the NFT, BLFT and the presence of a shockable rhythm was evaluated using a multivariable logistic regression adjusting for the registry version, age, sex, and public location. RESULTS: A total of 229,632 patients were logged in the registry, 50,957 of whom were included. Of these, 17,704 (34.7%) had an initial shockable rhythm. After the first minute, a significant decrease over time in the occurrence of shockable rhythm is observed but is slower when bystander cardiopulmonary resuscitation (CPR) is provided (each supplemental minute of BLFT: adjusted odds ratio = 0.95, 95 %CI = 0.94-0.95; each supplemental minute of NFT: adjusted odds ratio = 0.91, 95 %CI = 0.90-0.91]). CONCLUSIONS: In this large observational study, we were able to demonstrate that longer NFT were associated with lower odds of shockable presenting rhythms. Bystander CPR significantly mitigates the degradation of shockable rhythms over time, strengthening the need to improve bystander CPR rates around the world.

Opioid and non-opioid pain relief after an emergency department acute pain visit.

OBJECTIVES: Treatment of acute pain after emergency department (ED) discharge remains a challenge in the opioid crisis context. Our objective was to determine the proportion of patients using opioid vs non-opioid pain medication following discharge from the ED with acute pain, and the association of type of pain medication with average pain intensity before pain medication intake and report of pain relief. METHODS: This was a prospective cohort study of ED patients aged ≥ 18 years with an acute pain (≤ 2 weeks) who were discharged with an opioid prescription. Patients completed a 14-day diary assessing daily pain intensity level before each pain medication intake (0-10 numeric rating scale), type of pain medication use (opioid vs non-opioid), and if pain was relieved by the medication used that day. Multilevel analyses were used to compare the effect of type of analgesic used on pain intensity and relief. RESULTS: A total of 381 participants completed the 14-day diary; 50% were women and median age was 54 years (IQR = 43-66). Average daily pain intensity before pain medication intake was significantly higher for patients who used opioids (5.9; 95% CI 5.7-6.2) as compared to non-opioid analgesics (4.2; 95% CI 4.0-4.5) or no pain medication (2.2; 95% CI 1.9-2.5). Controlling for pain intensity, patients using opioids were more likely to report a pain relief (OR = 1.3; 95% CI 1.1-1.8) as compared to those who used non-opioid analgesics. CONCLUSION: Overall, opioids appear to be effective and used as intended by the prescribing physician.

RéSUMé: OBJECTIFS: Le traitement de la douleur aiguë après la sortie des départements d'urgence (DU) reste un défi dans le contexte de la crise des opioïdes. Notre objectif était de déterminer la proportion de patients utilisant des analgésiques opioïdes par rapport aux analgésiques non opioïdes après leur sortie des urgences avec une douleur aiguë, et l'association du type d'analgésique avec l'intensité moyenne de la douleur avant la prise d'analgésiques et le soulagement de la douleur rapporté. LES MéTHODES: Il s'agissait d'une étude de cohorte prospective de patients (DU) âgés de ≥18 ans souffrant de douleurs aiguës (≤ 2 semaines) et ayant reçu une ordonnance d'opioïdes à leur sortie de l'hôpital. Les patients ont rempli un journal de 14 jours évaluant le niveau d'intensité de la douleur quotidienne avant chaque prise de médicaments anti-douleur (échelle d'évaluation numérique de 0 à 10), le type d'utilisation des médicaments anti-douleur (opioïdes contre non opioïdes), et si la douleur était soulagée par les médicaments utilisés ce jour-là. Des analyses multiniveaux ont été utilisées pour comparer l'effet du type d'analgésique utilisé sur l'intensité et le soulagement de la douleur. RéSULTATS: Au total, 381 participants ont rempli le journal de 14 jours; 50% étaient des femmes et l'âge médian était de 54 ans (EI = 43­66). L'intensité moyenne de la douleur quotidienne avant la prise d'analgésiques était significativement plus élevée chez les patients qui prenaient des opioïdes (5.9; 95% IC: 5.7­6.2) par rapport aux analgésiques non opioïdes (4.2; 95% IC: 4.0­4.5) ou à l'absence d'analgésiques (2.2; 95% IC: 1.9­2.5). En contrôlant l'intensité de la douleur, les patients utilisant des opioïdes étaient plus susceptibles de déclarer un soulagement de la douleur (OR = 1.3; 95% CI: 1.1−1.8) par rapport à ceux qui utilisaient des analgésiques non opioïdes. CONCLUSION: Dans l'ensemble, les opioïdes semblent être efficaces et utilisés comme prévu par le médecin prescripteur.

Oxygen Therapy and Risk of Infection for Health Care Workers Caring for Patients With Viral Severe Acute Respiratory Infection: A Systematic Review and Meta-analysis.

STUDY OBJECTIVE: To synthesize the evidence regarding the infection risk associated with different modalities of oxygen therapy used in treating patients with severe acute respiratory infection. Health care workers face significant risk of infection when treating patients with a viral severe acute respiratory infection. To ensure health care worker safety and limit nosocomial transmission of such infection, it is crucial to synthesize the evidence regarding the infection risk associated with different modalities of oxygen therapy used in treating patients with severe acute respiratory infection. METHODS: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched from January 1, 2000, to April 1, 2020, for studies describing the risk of infection associated with the modalities of oxygen therapy used for patients with severe acute respiratory infection. The study selection, data extraction, and quality assessment were performed by independent reviewers. The primary outcome measure was the infection of health care workers with a severe acute respiratory infection. Random-effect models were used to synthesize the extracted data. RESULTS: Of 22,123 citations, 50 studies were eligible for qualitative synthesis and 16 for meta-analysis. Globally, the quality of the included studies provided a very low certainty of evidence. Being exposed or performing an intubation (odds ratio 6.48; 95% confidence interval 2.90 to 14.44), bag-valve-mask ventilation (odds ratio 2.70; 95% confidence interval 1.31 to 5.36), and noninvasive ventilation (odds ratio 3.96; 95% confidence interval 2.12 to 7.40) were associated with an increased risk of infection. All modalities of oxygen therapy generate air dispersion. CONCLUSION: Most modalities of oxygen therapy are associated with an increased risk of infection and none have been demonstrated as safe. The lowest flow of oxygen should be used to maintain an adequate oxygen saturation for patients with severe acute respiratory infection, and manipulation of oxygen delivery equipment should be minimized.

Use of tabletop exercises for healthcare education: a scoping review protocol.

INTRODUCTION: There is a growing interest in developing interprofessional education (IPE) in the community of healthcare educators. Tabletop exercises (TTX) have been proposed as a mean to cultivate collaborative practice. A TTX simulates an emergent situation in an informal environment. Healthcare professionals need to take charge of this situation as a team through a discussion-based approach. As TTX are gaining in popularity, performing a review about their uses could guide educators and researchers. The aim of this scoping review is to map the uses of TTX in healthcare. METHODS AND ANALYSIS: A search of the literature will be conducted using medical subject heading terms and keywords in PubMed, Medline, EBM Reviews (Evidence-Based Medicine Reviews), CINAHL (Cumulative Index of Nursing and Allied Health Literature), Embase and ERIC (Education Resources Information Center), along with a search of the grey literature. The search will be performed after the publication of this protocol (estimated to be January 1st 2020) and will be repeated 1 month prior to the submission for publication of the final review (estimated to be June 1st 2020). Studies reporting on TTX in healthcare and published in English or French will be included. Two reviewers will screen the articles and extract the data. The quality of the included articles will be assessed by two reviewers. To better map their uses, the varying TTX activities will be classified as performed in the context of disaster health or not, for IPE or not and using a board game or not. Moreover, following the same mapping objective, outcomes of TTX will be reported according to the Kirkpatrick model of outcomes of educational programs. ETHICS AND DISSEMINATION: No institutional review board approval is required for this review. Results will be submitted for publication in a peer-reviewed journal. The findings of this review will inform future efforts to TTX into the training of healthcare professionals.

Side effects from opioids used for acute pain after emergency department discharge.

OBJECTIVE: Opioid side effects are common when treating chronic pain. However, the frequency of opioid side effects has rarely been examined in acute pain conditions, particularly in a post emergency department (ED) setting. The objective of this study was to evaluate the short-term incidence of opioid-induced side effects (constipation, nausea/vomiting, dizziness, drowsiness, sweating, and weakness) in patients discharged from the ED with an opioid prescription. METHODS: This is a prospective cohort study of patients aged ≥18 years who visited the ED for an acute pain condition (≤2 weeks) and were discharged with an opioid prescription. Patients completed a 14-day diary assessing daily pain medication use and side effects. RESULTS: We recruited 386 patients with a median age of 54 years (IQR:43-66); 50% were women. During the 2-week follow-up, 80% of patients consumed opioids. Among the patients who used opioids, 79% (95%CI:75-83) reported side effects compared to 38% (95%CI:27-49) for non-users. Adjusting for age, sex, and pain condition, patients who used opioids were more likely to report constipation (OR:7.5; 95%CI:3.1-17.9), nausea/vomiting (OR:4.1; 95%CI:1.8-9.5), dizziness (OR:5.4; 95%CI: 2.2-13.2), drowsiness (OR:4.6; 95%CI:2.5-8.7), and weakness (OR:4.2; 95%CI:1.6-11.0) compared to non-users. A dose-response trend was observed for constipation but not for the other side effects. Nausea/vomiting (OR:2.0; 95%CI:1.1-3.6) and dizziness (OR:1.9; 95%CI:1.1-3.4) were more often associated with oxycodone than with morphine. CONCLUSION: As observed for chronic pain treatment, side effects are highly prevalent during short-term opioid treatment for acute pain. Physicians should inform patients about those side effects and should consider prescribing laxatives.

Perceptions of Emergency Medicine Residents of Multisource Feedback: Different, Relevant, and Useful Information.

STUDY OBJECTIVE: Multisource feedback is a process through which different members of the care team assess and provide feedback on residents' competencies, usually those that are less often addressed by traditional assessment methods (ie, communication, collaboration, and professionalism). Feasibility and reliability of multisource feedback have been addressed in previous research. The present study explores emergency residents' perceptions of multisource feedback provided by teaching physicians, nurses, and patients they have worked with during a rotation in an emergency department (ED). METHODS: A multisource feedback intervention was proposed to residents during 9 months in the ED of a tertiary care university hospital. Residents distributed feedback questionnaires to physicians, nurses, and patients that focused on competencies (collaboration, communication, and professionalism) from the CanMEDS framework. Responses were compiled and reported to participating residents. To assess residents' perceptions of multisource feedback, semistructured group and individual interviews were held 3 months after the intervention. Transcripts were analyzed qualitatively, following Miles and Huberman's method for intrasite case analysis. RESULTS: According to residents (n=10), each source (physicians, nurses, and patients) provided relevant comments that differed significantly in their content. Physicians focused primarily on medical expertise; nurses addressed competencies related to leadership, collaboration, and communication; and patients commented on the competencies of professionalism and communication. Residents concluded that obtaining feedback from nurses and patients was acceptable and useful. They reported modifying certain behaviors after receiving the multisource feedback. CONCLUSION: Residents perceived the multisource feedback to be acceptable and useful for the assessment of medical competencies such as communication, collaboration, professionalism, and leadership.

Opioid Use and Misuse Three Months After Emergency Department Visit for Acute Pain.

BACKGROUND: Studies evaluating long-term prescription opioid use are retrospective and based on filled opioid prescriptions from governmental databases. These studies cannot evaluate if opioids were really consumed and are unable to differentiate if they were used for a new pain or chronic pain or were misused. The aim of this study was to assess opioid use rate and reasons for consuming 3 months after being discharged from the emergency department (ED) with an opioid prescription. METHODS: This is a prospective cohort study conducted in the ED of a tertiary care urban center with a convenience sample of discharged patients ≥ 18 years who consulted for an acute pain condition (≤2 weeks). Three months post-ED visit, participants were interviewed by phone on their past 2-week opioid consumption and their reasons for consuming: a) for pain related to the initial ED visit, b) for a new unrelated pain, or c) for another reason. RESULTS: Of the 524 participants questioned at 3 months (mean ± SD age = 51 ± 16 years, 47% women), 47 patients (9%, 95% confidence interval [CI] = 7%-12%) reported consuming opioids in the previous 2 weeks. Among those, 34 (72%) reported using opioids for their initial pain, nine (19%) for a new unrelated pain and four (9%) for another reason (0.8%, 95% CI = 0.3%-2.0%, of the whole cohort). Patients who used opioids during the 2 weeks after the ED visit were 3.8 (95% CI = 1.2-12.7) times more likely to consume opioids at 3 months. CONCLUSION: Opioid use at the 3-month follow-up in ED patients discharged with an opioid prescription for an acute pain condition is not necessarily associated with opioid misuse; 91% of those patients consumed opioids to treat pain. Of the whole cohort, less than 1% reported using opioids for reasons other than pain. The rate of long-term opioid use reported by prescription-filling database studies should not be viewed as a proxy for incidence of opioid misuse.

Acute Pain Resolution After an Emergency Department Visit: A 14-Day Trajectory Analysis.

STUDY OBJECTIVE: The objective of the study is to evaluate the acute pain intensity evolution in emergency department (ED) discharged patients, using group-based trajectory modeling. This method identifies patient groups with similar profiles of change over time without assuming the existence of a particular pattern or number of groups. METHODS: This was a prospective cohort study of ED patients aged 18 years or older, with an acute pain condition (≤2 weeks), and discharged with an opioid prescription. Patients completed a 14-day diary assessing daily pain intensity level (numeric rating scale of 0 to 10) and pain medication use. RESULTS: Among the 372 included patients, 6 distinct post-ED pain intensity trajectories were identified. Two started with severe levels of pain; one remained with severe pain intensity (12.6% of the sample) and the other ended with a moderate pain intensity level (26.3%). Two other trajectories had severe initial pain; one decreased to mild pain (21.7%) and the other to no pain (13.8%). Another trajectory had moderate initial pain that decreased to a mild level (15.9%) and the last one started with mild pain intensity and had no pain at the end of the 14-day period (9.7%). The pain trajectory patterns were significantly associated with age, type of painful conditions, pain intensity at ED discharge, and opioid consumption. CONCLUSION: Acute pain resolution after an ED visit seems to progress through 6 different trajectory patterns that are more informative than simple linear models and could be useful to adapt acute pain management in future research.
