Critically ill patients must often be transferred between facilities to allow for higher levels of care. However, this phase of care may pose risks for complications and clinical deterioration due to exposure to out-of-hospital environments and decreased ability to monitor and intervene. This can nevertheless be mitigated by following general transport principles, with an adequate preparation, using a structured approach.

To estimate the cumulative incidence of functional decline over 6 months following emergency department (ED) assessments of nonhospitalized injuries and to identify its main determinants.We conducted a prospective multicenter cohort of older adults discharged home following assessment for injuries in 8 Canadian EDs. Participants were assessed at 3 time points: baseline in the ED, 3 months, and 6 months. The primary outcome, functional decline, was defined as a 2-points loss from baseline on the Older American Resources Scale (OARS). Other measures included demographics, comorbidities, injury characteristics, frailty, cognition, mobility status, etc. Cumulative incidences were estimated using proportions with 95% confidence intervals. Log-binomial regressions and the "least absolute shrinkage and selection operator" (LASSO) were used to identify significant functional decline determinants.Among 2,919 participants, 403 (13.8%) were lost to follow-up. Mean age was 76.2±7.6 years, 65.3% were women, 9% were frail, and 40.0% prefrail. Main injury mechanisms were falls (65.5%) and motor vehicle accidents (18.6%). The cumulative incidence of functional decline over 6 months was 17.0% (95% confidence interval 12.5% to 23.0%). Occasional use of walking devices, less than 5 outings/week, frailty, and older age were significant baseline determinants of functional decline.A significant 17% of older adults with "minor" injuries experience a persistent functional decline over 6 months following their ED visit. Four frailty-related determinants were identified: occasional use of a walking device, less than 5 outings/week, frailty, and older age. Further work is needed to assess if these can help ED clinicians screen seniors at risk and initiate interventions at discharge.

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).Retrospective analysis of prospectively collected data.Prehospital OHCA in eight U.S. and three Canadian sites.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.Sensitivity, specificity, and likelihood ratios of an initial shockable rhythm to identify patients with an NFT less than or equal to 5 minutes.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).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.

Background Buprenorphine-naloxone (BUP) initiation in emergency departments improves follow-up and survival among patients with opioid use disorder. We aimed to assess self-reported BUP-related practices and attitudes among emergency physicians. Methods We designed a cross-sectional physician survey by adapting a validated questionnaire on opioid harm reduction practices, attitudes and barriers. We recruited physician leads from 6 Canadian provinces to administer surveys to the staff physicians in their emergency department groups between December 2018 and November 2019. We included academic and community non-locum emergency department staff physicians. We excluded responses from emergency department groups with response rates less than 50% to minimize nonresponse bias. Primary (BUP prescribing practices) and secondary (willingness and attitudes) outcomes were analyzed using descriptive statistics. Results After excluding 1 group for low response (9/26 physicians), 652 of 798 (81.7%) physicians responded from 22 groups serving 34 emergency departments. Among respondents, 64.1% (95% confidence interval [CI] 60.4%-67.8%, emergency department group range 7.1%-100.0%) had prescribed BUP at least once in their career, 38.4% had prescribed it for home initiation and 24.8% prescribed it at least once a month. Overall, 68.9% (95% CI 65.3%-72.4%, emergency department group range 24.1%-97.6%) were willing to administer BUP, 64.2% felt it was a major responsibility and 37.1% felt they understood people who use drugs. Respondents most frequently rated lack of adequate training (58.2%) and lack of time (55.2%) as very important barriers to BUP initiation. Interpretation Two-thirds of the emergency physicians surveyed prescribed BUP, although only one-quarter did so regularly and one-third prescribed it for home initiation; wide variation between emergency department groups existed. Strategies to increase BUP initiation must address physicians' lack of time and training for BUP initiation and improve their understanding of people who use drugs.

This study compared effects of exercise-based interventions with usual care on functional decline, physical performance, and health-related quality of life (12-item Short-Form health survey) at 3 and 6 months after minor injuries, in older adults discharged from emergency departments. Participants were randomized either to the intervention or control groups. The interventions consisted of 12-week exercise programs available in their communities. Groups were compared on cumulative incidences of functional decline, physical performances, and 12-item Short-Form health survey scores at all time points. Functional decline incidences were: intervention, 4.8% versus control, 15.4% (p = .11) at 3 months, and 5.3% versus 17.0% (p = .06) at 6 months. While the control group remained stable, the intervention group improved in Five Times Sit-To-Stand Test (3.0 ± 4.5 s, p

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.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.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.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 = 43–66). 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: 5.7–6.2) par rapport aux analgésiques non opioïdes (4.2; 95% IC: 4.0–4.5) ou à l'absence d'analgésiques (2.2; 95% IC: 1.9–2.5). 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.

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.

Background the aim of this study was to evaluate the impact of emergency department (ED) stay-associated delirium on older patient’s functional and cognitive status at 60 days post ED visit. Methods this study was part of the multi-centre prospective cohort INDEED study. This project took place between March 2015 and July 2016 in five participating EDs across the province of Quebec. Independent non-delirious patients aged ≥65, with an ED stay ≥8 hours, were monitored for delirium until 24 hours post ward admission. A 60-day follow-up phone assessment was conducted. Participants were screened for delirium using the Confusion Assessment Method. Functional and cognitive statuses were assessed at baseline and at the 60-day follow-up using OARS and TICS-m. Results a total of 608 patients were recruited, 393 of which completed the 60-day follow-up. The Confusion Assessment Method was positive in 69 patients (11.8%) during ED stay or within the first 24 hours following ward admission. At 60 days, delirium patients experienced an adjusted loss of −2.9/28 [95%CI: −3.9, −2.0] points on the OARS scale compared to non-delirious patients who lost −1.6 [95%CI: −1.9, −1.3] (P = 0.006). A significant adjusted difference in cognitive function was also noted at 60 days, as TICS-m scores in delirious patients decreased by −1.6 [95%CI: −3.5, 0.2] compared to non-delirious patients, who showed a minor improvement of 0.5 [95%CI: −0.1, 1.1] (P = 0.03). Conclusion seniors who developed ED stay-associated delirium have lower baseline functional and cognitive status than non-delirious patients, and they will experience a more significant decline at 60 days post ED visit.

Objectives: The opioid crisis has risen dramatically in North America in the new millennium, due to both illegal and prescription opioid use. While emergency departments (EDs) represent a potentially strategic setting for interventions to reduce harm from opioid use disorder (OUD), the absence of a recent synthesis of literature limits implementation and scalability. To fill this gap, we conducted a systematic review of the literature on interventions targeting opioid use disorders initiated in emergency departments. Methods: Using an explicit search strategy (PROSPERO), the MEDLINE, CINAHL Complete, EMBASE and EBM reviews databases were searched from 1980 to October 4, 2019. The grey literature was explored using Google Scholar. Study characteristics were abstracted independently. The methodological quality and risk of bias were assessed. Results: 12 of 2270 studies met the inclusion criteria (two of high quality). In addition to the heterogeneity of the outcome measures used (retention in treatment, opioid consumption, overdose), brief intervention and buprenorphine initiation (6 of 12 studies) were the most documented with mixed effects for the former and positive short-term and confined to single ED sites effects for the latter. Conclusion: EDs can be an appropriate setting for initiating opioid agonist treatment (OAT), but in order to be sustained, it likely needs to be coupled with community-based follow-up and support to ensure longer-term retention. The scarcity of high-quality evidence on OUD interventions initiated in emergency settings highlights the need for future research.

Objectives1) To characterize mild, moderate, and severe fear of falling in older emergency department (ED) patients for minor injuries, and 2) to assess whether fear of falling could predict falls and returns to the ED within 6 months of the initial ED visit.MethodsThis study was part of the Canadian Emergency and Trauma Initiative (CETI) prospective cohort (2011–2016). Patients ages ≥ 65, who were independent in their basic daily activities and who were discharged from the ED after consulting for a minor injury, were included. Fear of falling was measured by the Short Falls Efficacy Scale International (SFES-I) in order to stratify fear of falling as mild (SFES-I = 7-8/28), moderate (SFES-I = 9-13/28), or severe (SFES-I = 14-28/28). Many other physical and psychological characteristics where collected. Research assistants conducted follow-up phone interviews at 3 and 6 months’ post-ED visit, in which patients were asked to report returns to the ED.ResultsA total of 2,899 patients were enrolled and 2,009 had complete data at 6 months. Patients with moderate to severe fear of falling were more likely to be of ages ≥ 75, female, frailer with multiple comorbidities, and decreased mobility. Higher baseline fear of falling increased the risk of falling at 3 and 6 months (odds ratio [OR]-moderate-fear of falling: 1.63, p < 0.05, OR-severe-fear of falling 2.37, p < 0.05). Fear of falling positive predictive values for return to the ED or future falls were 7.7% to 17%.ConclusionAlthough a high fear of falling is associated with increased risk of falling within 6 months of a minor injury in older patients, fear of falling considered alone was not shown to be a strong predictor of return to the ED and future falls.

Emergency department (ED) stay and its associated conditions (immobility, inadequate hydration and nutrition, lack of stimulation) increase the risk of delirium in older patients. Poorly controlled pain and paradoxically opioid pain treatment have also been identified as triggers for delirium. The aim of this study was to assess the relationship between pain, opioid treatment, and delirium in older ED patients.A multicenter prospective cohort study was conducted in four hospitals across the province of Québec (Canada). Patients aged ≥ 65 years old, waiting for hospital admission between March and July 2015, who were nondelirious upon ED arrival, who were independent or semi-independent in their daily living activities, and who had an ED stay of at least 8 hours were included. Delirium assessments were conducted twice a day during the patient's entire ED stay and their first 24 hours on the hospital ward using the Confusion Assessment Method. Pain intensity was evaluated using a visual analog scale (VAS = 0-100) during the initial interview, and all opioid treatments were documented.A total of 338 patients were included; 51% were female, and mean (±SD) age was 77 (±8) years. Forty-one patients (12%) experienced delirium during their hospital stay occurring within a mean (±SD) delay of 47 (±19) hours after ED admission. Among patients with pain intensity ≥ 65 from VAS (0-100), 26% experienced delirium compared to 11% for patients with pain 65 (p 0.01), and no significant association was found between opioid consumption and delirium (p = 0.31). Logistic regression controlling for confounding factors showed that patients with pain intensity ≥ 65 are 3.3 (95% confidence interval = 1.4 to 7.9) times more likely to develop delirium than patients who had pain intensity of65.Severe pain, not opioids, is associated with the development of delirium during ED stay. Adequate pain control during the hospital stay may contribute to a decrease in delirium episodes.

Background Patients hospitalized following a traumatic injury will be frequently treated with opioids during their stay and after discharge. We examined the relationship between acute phase ( Methods In a retrospective multicenter cohort study conducted on registry data, we included all patients ≥65 years admitted (hospital stay >2 days) for injury in 57 trauma centers in the province of Quebec (Canada) between 2004 and 2014. We searched for opioid poisoning and opioid use disorder from ICD-9 to ICD-10 code diagnosis after their initial injury. Patients that filled an opioid prescription within a 3-month period after sustaining the trauma were compared to those who did not, using Cox proportional hazards regressions. Results A total of 70,314 admissions were retained for analysis; median age was 82 years (IQR: 75-87), 68% were women, and 34% of the patients filled an opioid prescription within 3 months of the initial trauma. During a median follow-up of 2.6 years (IQR: 1-5), 192 participants (0.27%; 95% CI: 0.23%-0.31%) were hospitalized for opioid poisoning and 73 (0.10%; 95% CI: 0.08%-0.13%) were diagnosed with opioid use disorder. Having filled an opioid prescription within 3 months of injury was associated with an increased hazard ratio of opioid poisoning (2.8; 95% CI: 2.1-3.8) and opioid use disorder (4.2; 95% CI: 2.4-7.4) after the injury. However, history of opioid poisoning (2.6; 95% CI: 1.1-5.8), of substance use disorder (4.3; 95% CI: 2.4-7.7), or of the opioid prescription filled (2.8; 95% CI: 2.2-3.6) before the trauma, was also related to opioid poisoning or opioid use disorder after the injury. Conclusion Opioid poisoning and opioid use disorder are rare events after hospitalization for trauma in older patients. However, opioids should be used cautiously in patients with a history of substance use disorder, opioid poisoning or opioid use.

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.

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. 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. 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]). 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.

Currently, there are no Canadian guidelines for discharge instruction to be given to patients receiving an opioid prescription in the ED. This likely contributes to inadequate discharge instructions for these potentially dangerous medications. The principal goal of this study was to develop an interdisciplinary Canadian consensus regarding important concepts to be included in written opioid discharge instructions within the ED setting.We conducted a modified Delphi study between May and August 2021. The national multidisciplinary panel consisted of 23 healthcare professionals and one patient partner. The survey consisted of 19 initial concepts developed after a review of the literature and a meeting with local experts. The panel added four new concepts after the first survey round. Three rounds of online surveys were distributed in total. Panel consensus was defined a priori as a disagreement index score less than 1, in accordance with the RAND/UCLA Appropriateness Method.We achieved a 100% response rate in round one and a 96% response rate in rounds two and three of our Delphi study. There was group consensus (disagreement index = 0.66, median importance = 9) that all patients receiving opioid prescriptions from the ED should receive written discharge instructions. The interdisciplinary panel arrived at a consensus on 21/23 concepts for ED opioid discharge instructions. The concepts with the highest level of agreement were related to minimizing the use of the prescribed opioid medication and opioid use safety (mixing with drugs/alcohol, storage, and impairment).This Delphi study with a national, multidisciplinary panel achieved consensus on 21 concepts that should be included in written discharge instructions to patients receiving an opioid prescription upon discharge from the ED.RéSUMé: OBJECTIFS: Actuellement, il n’y a pas de lignes directrices canadiennes sur les instructions de sortie à donner aux patients qui reçoivent une ordonnance d'opioïdes aux urgences. Cela contribue probablement à des instructions de sortie inadéquates pour ces médicaments potentiellement dangereux. L’objectif principal de cette étude était d’établir un consensus canadien interdisciplinaire sur les concepts importants à inclure dans les directives écrites de sortie des opioïdes dans le contexte des urgences. MéTHODES: Nous avons mené une étude Delphi modifiée entre mai et août 2021. Le comité national multidisciplinaire était composé de 23 professionnels de la santé et d’un patient partenaire. L’enquête comprenait 19 concepts initiaux développés après un examen de la littérature et une réunion avec des experts locaux. Le panel a ajouté quatre nouveaux concepts après la première ronde d’enquête. Trois séries de sondages en ligne ont été distribuées au total. Le consensus du panel a été défini a priori comme un indice de désaccord inférieur à 1, conformément à la méthode de pertinence RAND/UCLA. RéSULTATS: Nous avons atteint un taux de réponse de 100 % au premier tour et un taux de réponse de 96 % aux deuxième et troisième tours de notre étude Delphi. Il y avait un consensus de groupe (indice de désaccord = 0,66, importance médiane = 9) sur le fait que tous les patients recevant une ordonnance d'opioïdes aux urgences devraient recevoir des instructions écrites à la sortie de l'hôpital. Le groupe interdisciplinaire est parvenu à un consensus sur les concepts 21/23 pour les instructions de sortie d’opioïdes aux urgences. Les concepts ayant fait l’objet du plus haut niveau d’entente étaient liés à la réduction de l’utilisation des médicaments opioïdes prescrits et à la sécurité de l’utilisation des opioïdes (mélange avec les drogues/alcool, stockage et affaiblissement des facultés). CONCLUSION: Cette étude Delphi avec un panel national multidisciplinaire a permis de parvenir à un consensus sur 21 concepts qui devraient être inclus dans les instructions écrites de sortie aux patients recevant une ordonnance d’opioïdes à leur sortie de l’urgence.

This study aimed to assess the feasibility and acceptability of remote physical exercise (PE) to prevent mobility loss among pre-disabled older adults during the COVID-19 lockdowns.Participants followed a 12-week PE remote program in Zoom© supervised groups (Web-Ex group, n=11) or phone-supervised individual booklet-based home-program (Booklet group, n=33).The total rate of adherence was 82.5% in the Web-Ex group and 85.8% in the Booklet group. The level of satisfaction was « a lot » for 60% of the participants in the Web-ex group and for 37.9% of those included in the Booklet group. Respectively 10% and 31% of the participants rated the difficulty as « low » in the web-ex and Booklet groups.Remote physical exercise using a web technology or booklets at home with regular and personalized follow-up during the lockdown was feasible and acceptable among pre-disabled seniors.

Analgesia with fentanyl can be associated with hyperalgesia (higher sensitivity to pain) and can contribute to escalating opioid use. Our objective was to assess the relationship between emergency department (ED) acute pain management with fentanyl compared to other opioids, and the quantity of opioids consumed two-week after discharge. We hypothesized that the quantity of opioids consumed would be higher for patients treated with fentanyl compared to those treated with other opioids.Patients were selected from two prospective cohorts assessing opioids consumed after ED discharge. Patients ≥18 years treated with an opioid in the ED for an acute pain condition (≤2 weeks) and discharged with an opioid prescription were included. Patients completed a 14-day paper or electronic diary of pain medication use. Quantity of 5 mg morphine equivalent tablets consumed during a 14-day follow-up by patients treated with fentanyl compared to those treated with other opioids during their ED stay were analyzed using a multiple linear regression and propensity scores.We included 707 patients (mean age ± SD: 50 ± 15 years, 47% women) in this study. During follow-up, patients treated with fentanyl (N = 91) during their ED stay consumed a median (IQR) of 5.8 (14) 5 mg morphine equivalent pills compared to 7.0 (14) for those treated with other opioids (p = 0.05). Results were similar using propensity score sensitivity analysis. However, after adjusting for confounding variables, ED fentanyl treatment showed a trend, but not a statistically significant association with a decreased opioid consumption during the 14-day follow-up (B = -2.4; 95%CI = -5.3 to 0.4; p = 0.09).Patients treated with fentanyl during ED stay did not consume more opioids after ED discharge, compared to those treated with other opioids. If fentanyl does cause more hyperalgesia compared to other opioids, it does not seem to have a significant impact on opioid consumption after ED discharge.

Background Emergency departments (EDs) are operating at or above capacity, which has negative consequences on patients in terms of quality of care and morbi-mortality. Redirection strategies for low-acuity ED patients to primary care practices are usually based on subjective eligibility criteria that sometimes necessitate formal medical assessment. Literature investigating the effect of those interventions is equivocal. The aim of the present study was to assess the safety of a redirection process using an electronic clinical support system used by the triage nurse without physician assessment. Methods A single cohort observational study was performed in the ED of a level 1 academic trauma center. All low-acuity patients redirected to nearby clinics through a clinical decision support system (February–August 2017) were included. This system uses different sets of medical prerequisites to identify patients eligible to redirection. Data on safety and patient experience were collected through phone questionnaires on day 2 and 10 after ED visit. The primary endpoint was the rate of redirected patients returning to any ED for an unexpected visit within 48 h. Secondary endpoints were the incidence of 7-day return visit and satisfaction rates. Results A total of 980 redirected low-acuity patients were included over the period: 18 patients (2.8%) returned unexpectedly to an ED within 48 h and 31 patients (4.8%) within 7 days. No hospital admission or death were reported within 7 days following the first ED visit. Among redirected patients, 81% were satisfied with care provided by the clinic staff. Conclusion The implementation of a specific electronic-guided decision support redirection protocol appeared to provide safe deferral to nearby clinics for redirected low-acuity patients. EDs are pivotal elements of the healthcare system pathway and redirection process could represent an interesting tool to improve the care to low-acuity patients.

There is a complex relationship among opioids, sleep and daytime function. Patients and medical providers should be aware that chronic opioid therapy can alter sleep architecture and sleep quality as well as contribute to daytime sleepiness. It is also important for medical providers to be cognizant of other adverse effects of chronic opioid use including the impact on respiratory function during sleep. Opioids are associated with several types of sleep-disordered breathing, including sleep-related hypoventilation, central sleep apnea (CSA), and obstructive sleep apnea (OSA). Appropriate screening, diagnostic testing, and treatment of opioid-associated sleep-disordered breathing can improve patients’ health and quality of life. Collaboration among medical providers is encouraged to provide high quality, patient-centered care for people who are treated with chronic opioid therapy.

Background There is variability in the management of patients presenting to the emergency department (ED) with mild traumatic brain injury (MTBI) and abnormal findings on their initial head computed tomography (CT). The main objective of this study was to validate the value of the Important Brain Injury (IBI) criteria, introduced by the Canadian CT-Head Rule, in predicting the need for surgical intervention. The secondary objective was to identify independent predictors for neurosurgical intervention. Methods This is a post hoc analysis of a prospective cohort of adult patients presenting to the ED of one tertiary care, academic center, between 2008 and 2012, with MTBI and an abnormal initial head CT. Neurosurgical intervention was at the discretion of the treating physician. The sensitivity and specificity of the IBI criteria were calculated with 95% confidence intervals (CI95%). A multivariate logistic regression model was used to identify independent predictors for neurosurgical intervention with the direct entry method. Results A total of 678 patients (male = 65.9%, mean age = 62.5 years) were included, of whom 114 (16.8%) required neurosurgical intervention. All patients requiring neurosurgical intervention met IBI criteria on their initial head CT (sensitivity of 100% [CI95% 96.8–100]). However, 368 (65.2%) patients with findings of IBI did not require neurosurgical intervention (specificity of 34.8% [CI95% 30.8–38.8]). Age over 65 was independently associated with neurosurgical intervention in the IBI population. Conclusion The IBI criteria for MTBI identified all patients who required neurosurgical intervention; however its specificity is low.

This study aimed to evaluate the association between the quantity of subcutaneous fat (assessed by skinfold thickness) and the inter-device agreement of 2 tissue oximeters.This is a prospective cohort study.This study was conducted in a tertiary care academic urban hospital.Healthy volunteers were recruited.All patients recruited had their tissue saturations and skinfold thickness measured at 4 different sites (shoulder, forearm, knee, and calf) on both sides of the body using 2 tissue oximeters, the INVOS 5100C and the EQUANOX 7600.Higher skinfold measures were associated with an increase in the difference between measures provided by both oximeters (slope = -0.59, Pearson correlation coefficient = -0.51, p0.001). This observed association persisted in a linear mixed model (-0.48 [95% confidence interval [CI] -0.61 to -0.36], p0.001). The sex of the volunteers also influenced the inter-oximeter agreement (women: -5.77 [95% CI -8.43 to -3.11], p0.001), as well as the forearm sites (left forearm: -7.16 [95% CI -9.85 to -4.47], p0.001; right forearm:-7.01 [95% CI -9.61 to -4.40], p0.001).The inter-device agreement of the 2 studied oximeters is correlated to the quantity of subcutaneous fat. Monitoring using tissue oximetry should be interpreted with great care when sensors are placed on sites with a significant quantity of subcutaneous fat. In addition to the monitoring of cerebral oximetry, following the variations of saturations at the same peripheral site seems to remain the most secure way to use that technology for the monitoring of critically ill patients.

Background It is documented that health professionals from various settings fail to detect > 50% of delirium cases. Objective This study aimed to describe the proportion of unrecognized incident delirium in five emergency departments (EDs). Secondary objectives were to compare the two groups (recognized/unrecognized) and assess the impact of unrecognized delirium at 60 days regarding 1) unplanned consultations and 2) functional and cognitive decline. Method This is a sub-analysis of a multicenter prospective cohort study. Independent patients aged ≥ 65 years who tested negative for delirium on the initial interview with an ED stay ≥ 8 h were enrolled. Patients were assessed twice daily using the Confusion Assessment Method (CAM) and the Delirium Index up to 24 h into hospital admission. Medical records were reviewed to assess whether delirium was recognized or not. Results The main study reported a positive CAM in 68 patients. Three patients’ medical files were incomplete, leaving a sample of 65 patients. Delirium was recognized in 15.4% of our participants. These patients were older (p = 0.03) and female (p = 0.01) but were otherwise similar to those with unrecognized delirium. Delirium Index scores were higher in patients with recognized delirium (p = 0.01) and they experienced a more important functional decline at 60 days (p = 0.02). No association was found between delirium recognition and health care services utilization or decline in cognitive function. Conclusions This study confirms reports of high rates of missed or unrecognized delirium (84.6%) in ED patients compared to routine structured screening using the CAM performed by a research assistant. Patients with recognized delirium were older women with a greater severity of symptoms and experienced a more significant functional decline at 60 days.

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.

Background It is recommended that older patients undergo systematic mental status screening when presenting to the emergency department (ED). However, the tools available are not necessarily adapted to the ED environment, therefore, quicker and easier tools are needed. Objectives The purpose of this study is to validate the Ottawa 3DY-French (O3DY-F) Scale as a screening tool for delirium and cognitive impairment in a French-speaking cohort. Method This multicenter prospective study was conducted in four hospitals across the province of Quebec. Inclusion criteria were: age ≥ 65 years, ED stay ≥ 8 h, awaiting admission to a care unit, and independent or semi-independent in their daily living activities. Cognitive status was assessed during the initial interview using the Telephone Interview for Cognitive Screening-modified (TICS-m) and the O3DY-F scale. Comparisons were made between the O3DY-F and the TICS-m and Confusion Assessment Method (CAM) to assess the sensitivity and specificity of the O3DY-F for the detection of cognitive impairment and delirium. Results A total of 313 patients were included in this study, 139 of which had a positive O3DY-F. When compared with the CAM, the O3DY-F had a sensitivity of 84.2% (95% confidence interval [CI] 60.4–96.6) and a specificity of 58.2% (95% CI 52.3–63.9) for the detection of prevalent delirium. The O3DY-F had a sensitivity of 76.2% (95% CI 66.7–84.8) and a specificity of 67.6% (95% CI 61.0–73.6) for cognitive impairment (defined as a TICS-m Conclusion The O3DY-F is a useful and effective tool to screen for delirium and undetected cognitive impairment among a French-speaking cohort in the ED.

ObjectivesTo determine the diagnostic yield of screening patients for SARS-CoV-2 who were admitted with a diagnosis unrelated to COVID-19, and identify risk factors for positive tests.DesignCohort from the Canadian COVID-19 Emergency Department Rapid Response Network (CCEDRRN) registrySetting30 acute care hospitals across CanadaParticipantsPatients hospitalized for non-COVID-19 related diagnoses who were tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) between March 1, and December 29, 2020Main outcomePositive nucleic acid amplification test (NAAT) for SARS-CoV-2Outcome measureDiagnostic yieldResultsWe enrolled 15,690 consecutive eligible adults who were admitted to hospital without clinically suspected COVID-19. Among these patients, 122 tested positive for COVID-19, resulting in a diagnostic yield of 0.8% (95% CI 0.64% – 0.92%). Factors associated with a positive test included presence of a fever, being a healthcare worker, having a positive household contact or institutional exposure, and living in an area with higher 7-day average incident COVID-19 cases.ConclusionsUniversal screening of hospitalized patients for COVID-19 across two pandemic waves had a low diagnostic yield and should be informed by individual-level risk assessment in addition to regional COVID-19 prevalence.Trial registrationNCT04702945SUMMARY BOXESSection 1: Universal screening of admitted patients for SARS-CoV-2 was implemented in many hospitals at the beginning of the pandemic. The Infections Diseases Society of America (IDSA) recommended avoiding universal screening of asymptomatic hospitalized patients in areas and times of low-COVID prevalence (defined as Section 2: This study supports IDSA recommendations to avoid universal screening for COVID-19 in times and areas of low COVID prevalence and identifies patient-level risk factors strongly associated with positive testing that should be considered for screening.

Buprenorphine-naloxone (BUP) initiation in emergency departments improves follow-up and survival among patients with opioid use disorder. We aimed to assess self-reported BUP-related practices and attitudes among emergency physicians.We designed a cross-sectional physician survey by adapting a validated questionnaire on opioid harm reduction practices, attitudes and barriers. We recruited physician leads from 6 Canadian provinces to administer surveys to the staff physicians in their emergency department groups between December 2018 and November 2019. We included academic and community non-locum emergency department staff physicians. We excluded responses from emergency department groups with response rates less than 50% to minimize nonresponse bias. Primary (BUP prescribing practices) and secondary (willingness and attitudes) outcomes were analyzed using descriptive statistics.After excluding 1 group for low response (9/26 physicians), 652 of 798 (81.7%) physicians responded from 22 groups serving 34 emergency departments. Among respondents, 64.1% (95% confidence interval [CI] 60.4%-67.8%, emergency department group range 7.1%-100.0%) had prescribed BUP at least once in their career, 38.4% had prescribed it for home initiation and 24.8% prescribed it at least once a month. Overall, 68.9% (95% CI 65.3%-72.4%, emergency department group range 24.1%-97.6%) were willing to administer BUP, 64.2% felt it was a major responsibility and 37.1% felt they understood people who use drugs. Respondents most frequently rated lack of adequate training (58.2%) and lack of time (55.2%) as very important barriers to BUP initiation.Two-thirds of the emergency physicians surveyed prescribed BUP, although only one-quarter did so regularly and one-third prescribed it for home initiation; wide variation between emergency department groups existed. Strategies to increase BUP initiation must address physicians' lack of time and training for BUP initiation and improve their understanding of people who use drugs.

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.
