Balanced crystalloids (RInger's lactate) versus normal Saline in adults with diabetic Ketoacidosis in the Emergency Department (BRISK-ED): a pilot randomised controlled trial.

BACKGROUND: Current diabetic ketoacidosis (DKA) treatment guidelines recommend using normal saline (NS); however, NS may delay DKA resolution by causing more hyperchloremic metabolic acidosis compared with balanced crystalloids. This study's objective was to determine the feasibility of a future multicentred randomised controlled trial (RCT) comparing intravenous Ringer's lactate (RL) with NS in managing ED patients with DKA. METHODS: We conducted a parallel-arm, triple-blind, pilot RCT of adults (≥18 years) with DKA at a Canadian academic tertiary care ED. The primary feasibility outcome was recruitment rate (target ≥41.3% of eligible participants over the 1-year study period); the primary efficacy outcome was time elapsed from ED presentation to DKA resolution. The superiority margin for a clinically significant difference was chosen to be a 40% time reduction to DKA resolution. We also assessed the need to break allocation concealment and loss to follow-up. Patients with clinical suspicion for DKA were screened for inclusion and enrolled patients were randomised 1:1 to receive RL or NS. Patients, clinicians and outcome assessors were blinded to allocation. RESULTS: We enrolled 52 (25 RL, 27 NS) of 60 eligible patients (86.7%), exceeding our target recruitment rate. There were more patients in the NS group with type 1 diabetes, and more patients in the RL group had an admission co-diagnosis in addition to DKA. For the 44 participants with confirmed laboratory evidence of resolution, median (IQR) time to DKA resolution for RL versus NS was 15.7 (10.4-18.8) and 12.7 (7.9-19.2) hours, respectively. There were no cases where blinding was broken, and there was no loss to follow-up. CONCLUSIONS: This pilot trial demonstrated our protocol's feasibility by exceeding our target recruitment rate. Our results may be used to inform future multicentre trials to compare the safety and efficacy of RL and NS in managing DKA in the ED. TRIAL REGISTRATION NUMBER: NCT04926740.

Virtual Coaching and the Reduction of Radial Head Subluxation: A Case Series.

OBJECTIVES: After the establishment of the virtual pediatric emergency medicine clinic at our institution, we noted that several physicians independently began to instruct caregivers virtually on reducing a radial head subluxation. We thus conducted a case series to investigate the number, success, and follow-ups for the virtual reduction of radial head subluxation. METHODS: The electronic medical records at our institution were searched from the inception of the virtual clinic in May 2020 until August 2022 (inclusive), for visits and discharge diagnosis containing the word "elbow" or "arm." RESULTS: Fourteen charts were retrieved; however, 2 were excluded because they were not a suspected radial head subluxation. A virtual reduction was attempted for eight (66.7%) of the 12 patients. In 6 of 8 patients (75.0%), the reduction was deemed successful, and for 2 patients (25.0%), it was deemed unsuccessful. Of the latter, one was found to have a nondisplaced radial neck fracture. All 4 patients (33.3%) for whom a virtual reduction was not attempted were referred to the emergency department. CONCLUSIONS: Virtual video coaching of pulled elbow reduction was completed at our institution with overall good success rate. All the physicians involved noted the essential need and benefits of video conferencing for successfully reducing radial head subluxation. We note that a pediatric population may be more amenable to video-based appointments than other populations due to their caregivers' familiarity with digital technology. Finally, as nonphysician models of healthcare delivery for virtual urgent care visits expand, we propose a checklist based on our experience to ensure patient safety.

3M™ Defib-Pads as a Reusable Alternative to Commercial Ultrasound Gel in Resource-Limited Settings.

INTRODUCTION: With point-of-care ultrasound (POCUS) use in austere environments comes the challenge of having an ever-available coupling medium for image generation. Commercial gel has numerous drawbacks that can limit its utility in these settings, and no studies have evaluated the potential for a reusable coupling medium. This study aimed to determine whether 3M™ Defib-Pads could be utilized as a reusable alternative to commercial gel for image generation in resource-limited settings. METHODS: A descriptive, cross-sectional survey of Canadian physicians with POCUS interest was conducted to evaluate the interpretability of various POCUS images in a blinded fashion. Three anatomic regions (cardiac, abdominal, and nerve) were utilized, and image generation from the commercial gel and 7 Defib-Pad conditions were evaluated. These included pads that were 1) newly opened, 2) dirtied then rinsed, 3) air dried, 4) rinsed after being air dried, 5) frozen then thawed, 6) used in double thickness, and 7) used with a probe cover. RESULTS: Compared to commercial gel, 3M™ Defib-Pads performed similarly, with adequate image interpretability of up to 100% in some conditions. The exception was pads that had prolonged air exposure, which produced images that were never interpretable. However, subsequent rinsing of these pads with water resulted in restored image generation. CONCLUSION: 3M™ Defib-Pads were found to produce interpretable POCUS images under multiple environmental stressors and with different modalities of use, suggesting that 3M™ Defib-Pads can perform as a reusable gel alternative in resource-limited settings.

Experience of emergency department patients after a visit for hyperglycaemia: implications for communication and factors affecting adherence postdischarge.

BACKGROUND: While studies have reported factors affecting adherence to diabetic care plans from a chronic disease perspective, no studies have addressed issues with post-discharge adherence facing patients with diabetes after an emergency department (ED) presentation for hyperglycaemia. This study's objectives were to describe patient perspectives on their experience during and after an ED visit for hyperglycaemia and to identify factors that influence postdischarge adherence. METHODS: We conducted a qualitative description (QD) study of adult patients who had visited a Canadian ED for hyperglycaemia. Consistent with QD, purposive sampling was utilised, seeking diversity across age, gender and diabetes type. Participants took part in semistructured interviews and thematic analysis was used to identify and describe core themes. Frequent team meetings were held to review the analysis and to develop the final list of themes used to recode the data set. Analytic insights were tracked using reflective memos and an audit trail documented all steps and decisions. RESULTS: 22 patients with type 1 and 2 diabetes were interviewed from June to October 2019. Participants identified several factors that impacted their ability to adhere to discharge plans: communication of instructions, psychosocial factors (financial considerations, shame and guilt, stigma and mental health), access to follow-up care and paediatric to adult care transitions. CONCLUSIONS: This study describes the patient experience with the communication of discharge instructions, as well as factors affecting adherence post-ED discharge for hyperglycaemia. Our findings suggest four strategies that could improve the patient experience, improve adherence to discharge plans and potentially decrease the frequency of recurrent ED visits for hyperglycaemia.

Seeking Care for Hyperglycemia in the Emergency Department: Through the Eyes of the Patient.

Health care systems often provide a range of options of care for patients with illnesses who do not require hospital admission. For individuals with diabetes, these options may include primary care providers, specialized diabetes clinics, and urgent care and walk-in clinics. We explored the reasons why patients choose the Emergency Department over other health care settings when seeking care for hyperglycemia.

Door-To-Triage Time in a Canadian Tertiary-Care Center.

BACKGROUND: The interval from patient arrival to triage is arguably the most dangerous time a patient spends in the emergency department (ED), as they are an unknown entity until assessed by a health care professional. OBJECTIVE: We sought to quantify door-to-triage time (DTT), an important factor in patient safety that has not yet been quantified in Canada. METHODS: Data were collected from all ambulatory patients presenting to a tertiary-care ED during a consecutive 7-day period. Demographic information, arrival time (door time), triage time, and Canadian Triage and Acuity Score (CTAS) were collected. DTT was compared across variables using Kruskal-Wallis one-way analysis of variance. RESULTS: Seven hundred and seventy-five patients were included in the study, representing 82.9% of ambulatory patients. DTT was variable (1-86 min) with a median of 12 min (interquartile range [IQR] 6-21 min). Patients in the 5th percentile with the longest DTT waited a median of 54 min (IQR 48-63 min). DTT varied across days of the week (p < 0.01); the longest wait was on Monday (median 22 [IQR 11-43] min) and the shortest on Sunday (median 8 [IQR 5-12] min). There was no relationship between DTT and CTAS (p = 0.12). CONCLUSIONS: DTT is an important variable affecting patient safety. Given site-specific factors, replication across additional centers is necessary. Additional research evaluating factors affecting DTT, different triage paradigms, and quality improvement interventions should be undertaken.

Predictors of Hypothermia upon Trauma Center Arrival in Severe Trauma Patients Transported to Hospital via EMS.

Introduction: Hypothermia in severe trauma patients can increase mortality by 25%. Active warming practices decrease mortality and are recommended in the Advanced Trauma Life Support (ATLS) guidelines. Despite this, many emergency medical services (EMS) vehicles do not carry equipment necessary to perform active warming. The intent of this study was to determine the rate of hypothermia in severe trauma patients upon major trauma center (MTC) arrival, as well as to characterize factors associated with hypothermia in trauma in order to devote potential resources to those at highest risk. Methods: This single-center retrospective chart review included adults (age ≥ 18) in the local trauma registry (trauma team activation or injury severity score ≥12) from January 2009 to June 2016. Logistic regression was used to identify predictors of hypothermia on MTC arrival. Results: A total of 3,070 patient charts were reviewed, of which 159 (5.2%) were hypothermic. Multivariate logistic regression identified 7 factors that were significantly associated with hypothermia on MTC arrival in severe trauma. Risk factors for hypothermia on MTC arrival after severe trauma included: intubation pre-MTC, increased number of co-morbidities, and increased injury severity. Conversely, protective factors against hypothermia were: higher initial systolic blood pressure (SBP), penetrating injury, referral to MTC, and higher ambient outdoor temperatures. Median length of stay in hospital was 7 days for hypothermic patients compared to 4 days for normothermic patients (Δ 3 days; p < 0.001). Only 69.2% of hypothermic patients survived to discharge compared to 93.9% of normothermic patients (Δ 24.7%; χ2 = 133.4, p < 0.001). Conclusions: This retrospective study of hypothermia in major trauma patients found a rate of hypothermia of 5%. Factors associated with higher risk of hypothermia include pre-MTC intubation, high ISS, multiple comorbidities, low SBP, non-penetrating mechanism of injury, and being transferred directly to MTC, and colder outdoor temperature. Avoidance of hypothermia is imperative to the management of major trauma patients. Prospective studies are required to determine if prehospital warming in these high-risk patients decreases the rate of hypothermia in major trauma and improves patient outcomes.

Evaluation of the Uptake of a Prehospital Cardiac Arrest Termination of Resuscitation Rule.

BACKGROUND: Previous research has focused on creation and validation of a basic life support rule for termination of resuscitation (TOR) in nontraumatic out-of-hospital cardiac arrest (OHCA) to identify patients who will not be successfully resuscitated or will not have a favorable outcome. Although now widely implemented, translational research regarding in-field compliance with TOR criteria and barriers to use is scarce. OBJECTIVES: This project aimed to assess compliance rates, barriers to use, and effect on ambulance transport rates after implementing TOR criteria for OHCA. METHODS: Retrospective chart review of patients ≥ 18 years with OHCA. Data from regional Emergency Medical Services agencies were collected to determine TOR rule compliance for patients meeting criteria, barriers to use, and effect of a TOR rule on ambulance transport. RESULTS: There were 552 patients with OHCAs identified. Ninety-one patients met TOR criteria, with paramedics requesting TOR in 81 (89%) cases and physicians granting requests in 65 (80.2%) cases. Perceived barriers to TOR compliance included distraught families, nearby advanced-care paramedics, and unusual circumstances. Reasons for physician refusal of TOR requests included hospital proximity, patient not receiving epinephrine, and poor communication connection to paramedics. Total high priority transports decreased 15.6% after implementation of a TOR rule. CONCLUSIONS: The study found high compliance after implementation of a TOR rule and identified potentially addressable barriers to TOR use. Appropriate application of a TOR rule led to reduction in high-priority ambulance transports, potentially reducing futile use of health care resources and risk of ambulance motor vehicle collisions.

Morbidity and Mortality Associated with Prehospital "Lift-assist" Calls.

INTRODUCTION: When an individual requires assistance with mobilization, emergency medical services (EMS) may be called. If a patient does not receive treatment on scene and is not transported to hospital, these are referred to as "Lift Assist" (LA) calls. It is possible this need for assistance represents a subtle onset of a disease process or decline in function. Without recognition or treatment, the patient may be at risk for recurrent falls, repeat EMS visits or worsening illness. OBJECTIVE: To examine the 14-day morbidity and mortality associated with LA calls and determine factors that are associated with increased risk of these outcomes. METHODS: All LA calls from a single EMS agency were collected over a one year study period (January-December 2013). Calls were linked with hospital records to determine if LA patients had a subsequent visit to the emergency department (ED), admission, or death within 14 days of the LA call. Logistic regression analyses were completed to determine factors predicting ED visit or hospital admission within 14 days of the LA call. RESULTS: Of 42,055 EMS calls, 804 (1.9%) were LAs. These calls were for 414 individuals; 298 (72%) patients had 1 LA, and 116 (28%) patients had >1 LA call. There were 169 (21%) ED visits, 93 (11.6%) hospital admissions and 9 (1.1%) deaths within 14 days of a LA call. Patient age (p = 0.025) significantly predicted ED visit. Patient age (p = 0.006) and an Ambulance Call Record missing at least 1 vital sign (p = 0.038) significantly predicted hospital admission. CONCLUSIONS: LA calls are associated with short-term morbidity and mortality. Patient age was found to be associated with these outcomes. These calls may be early indicators of problems requiring comprehensive medical evaluation and thus further factors associated with poor outcomes should be determined.

Predictors of 30-day recurrent emergency department visits for hyperglycemia in patients with types 1 and 2 diabetes: a population-based cohort study.

OBJECTIVES: This study's aims were to describe the outcomes of patients with diabetes presenting with their first ED visit for hyperglycemia, and to identify predictors of recurrent ED visits for hyperglycemia. METHODS: Using linked databases, we conducted a population-based cohort study of adult and pediatric patients with types 1 and 2 diabetes presenting with a first ED visit for hyperglycemia from April 2010 to March 2020 in Ontario, Canada. We determined the proportion of patients with a recurrent ED visit for hyperglycemia within 30 days of the index visit. Using multivariable regression analysis, we examined clinical and socioeconomic predictors for recurrent visits. RESULTS: There were 779,632 patients with a first ED visit for hyperglycemia. Mean (SD) age was 64.3 (15.2) years; 47.7% were female. 11.0% had a recurrent visit for hyperglycemia within 30 days. Statistically significant predictors of a recurrent visit included: male sex, type 1 diabetes, regions with fewer visible minority groups and with less education or employment, higher hemoglobin A1C, more family physician or internist visits within the past year, being rostered to a family physician, previous ED visits in the past year, ED or hospitalization within the previous 14 days, access to homecare services, and previous hyperglycemia encounters in the past 5 years. Alcoholism and depression or anxiety were positive predictors for the 18-65 age group. CONCLUSIONS: This population-level study identifies predictors of recurrent ED visits for hyperglycemia, including male sex, type 1 diabetes, regions with fewer visible minority groups and with less education or employment, higher hemoglobin A1C, higher previous healthcare system utilization (ED visits and hospitalization) for hyperglycemia, being rostered to a family physician, and access to homecare services. Knowledge of these predictors may be used to develop targeted interventions to improve patient outcomes and reduce healthcare system costs.

ABSTRAIT: OBJECTIFS: Les objectifs de cette étude étaient de décrire les résultats des patients diabétiques présentant leur première visite aux urgences pour hyperglycémie, et d'identifier les prédicteurs des visites récurrentes aux urgences pour hyperglycémie. MéTHODES: À l'aide de bases de données couplées, nous avons mené une étude de cohorte basée sur la population de patients adultes et pédiatriques atteints de diabète de type 1 et 2 présentant une première visite aux urgences pour l'hyperglycémie d'avril 2010 à mars 2020 en Ontario, au Canada. Nous avons déterminé la proportion de patients présentant une visite récurrente à l'urgence pour hyperglycémie dans les 30 jours suivant la visite d'index. À l'aide d'une analyse de régression multivariée, nous avons examiné les prédicteurs cliniques et socioéconomiques des visites récurrentes. RéSULTATS: Il y avait 779 632 patients avec une première visite à l'urgence pour hyperglycémie. L'âge moyen (ET) était de 64,3 (15,2) ans; 47,7% étaient des femmes. 11,0 % avaient une visite récurrente pour hyperglycémie dans les 30 jours. Les prédicteurs statistiquement significatifs d'une visite récurrente comprenaient le sexe masculin, le diabète de type 1, les régions comptant moins de groupes de minorités visibles et ayant moins d'études ou d'emploi, une hémoglobine A1C plus élevée, plus de visites chez un médecin de famille ou un interniste au cours de la dernière année, être inscrit auprès d'un médecin de famille, consulter le service d'urgence au cours de la dernière année, être hospitalisé au cours des 14 derniers jours, avoir accès à des services de soins à domicile et avoir été confronté à une hyperglycémie au cours des 5 dernières années. L'alcoolisme et la dépression ou l'anxiété étaient des prédicteurs positifs pour le groupe des 18-65 ans. CONCLUSIONS: Cette étude au niveau de la population identifie des prédicteurs de visites récurrentes aux urgences pour l'hyperglycémie, y compris le sexe masculin, le diabète de type 1, les régions avec moins de groupes de minorités visibles et avec moins d'études ou d'emploi, plus d'hémoglobine A1C, l'utilisation antérieure plus élevée du système de soins de santé (visites aux urgences et hospitalisation) pour l'hyperglycémie, le fait d'être inscrit auprès d'un médecin de famille et l'accès aux services de soins à domicile. La connaissance de ces prédicteurs peut être utilisée pour élaborer des interventions ciblées afin d'améliorer les résultats pour les patients et de réduire les coûts du système de santé.

Physician wellbeing and burnout in emergency medicine in Switzerland.

Emergency physicians are the most at-risk medical specialist group for burnout. Given its consequences for patient care and physician health and its resulting increased attrition rates, ensuring the wellbeing of emergency physicians is vital for preserving the integrity of the safety net for the healthcare system that is emergency medicine. In an effort to understand the current state of practicing physicians, this study reviews the results of the first national e-survey on physician wellbeing and burnout in emergency medicine in Switzerland. Addressed to all emergency physicians between March and April 2023, it received 611 complete responses. More than half of respondents met at least one criterion for burnout according to the Maslach Burnout Inventory - Human Services Survey (59.2%) and the Copenhagen Burnout Inventory (54.1%). In addition, more than half reported symptoms suggestive of mild to severe depression, with close to 20% screening positively for moderate to severe depression, nearly 4 times the incidence in the general population, according to the Patient Health Questionnaire-9. We found that 10.8% of respondents reported having considered suicide at some point in their career, with nearly half having considered this in the previous 12 months. The resulting high attrition rates (40.6% of respondents had considered leaving emergency medicine because of their working conditions) call into question the sustainability of the system. Coinciding with trends observed in other international studies on burnout in emergency medicine, this study reinforces the fact that certain factors associated with wellbeing are intrinsic to emergency medicine working conditions.

Challenges and strategies in the administration of a population based mortality follow-back survey design.

Population-based mortality follow-back survey designs have been used to collect information concerning end-of-life care from bereaved family members in several countries. In Canada, this design was recently employed to gather population-based information about the end-of-life care experience among adults in Nova Scotia as perceived by the decedent's family. In this article we describe challenges that emerged during the implementation of the study design and discuss resolutions strategies to help overcome them. Challenges encountered included the inability to directly contact potential participants, difficulties ascertaining eligibility, mailing strategy complications and the overall effect of these issues on response rate and subsequent sample size. Although not all challenges were amenable to resolution, strategies implemented proved beneficial to the overall process and resulted in surpassing the targeted sample size. The inability to directly contact potential participants is an increasing reality and limitations associated with this process best acknowledged during study development. Future studies should also consider addressing participant concerns pertaining to their eligibility and use of a more cost effective mailing strategy.

Adherence to antihypertensive medications among family practice patients with diabetes mellitus and hypertension.

OBJECTIVE: To measure adherence and to identify factors associated with adherence to antihypertensive medications in family practice patients with diabetes mellitus (DM) and hypertension. DESIGN: A cross-sectional study using a mailed patient self-report survey and clinical data. SETTING: Twenty-seven family physician and nurse practitioner clinics from Nova Scotia, New Brunswick, and Prince Edward Island (the Maritime Family Practice Research Network). PARTICIPANTS: A total of 527 patients with type 2 DM and hypertension who had had their blood pressure measured with the BpTRU (an automated oscillometric instrument) at family practice clinic visits within the previous 6 months. MAIN OUTCOME MEASURES: Level of adherence to antihypertension medications as measured by patients' self-report on the Morisky scale; association between high adherence on the Morisky scale and 22 patient factors related to demographic characteristics, clinical variables, knowledge, beliefs, behaviour, health care provider relationships, and health system influences. RESULTS: The survey response rate was 89.6%. The average age of patients was 66 years, and 51.6% of participants were men. Forty-three percent of patients had had a diagnosis of DM for more than 10 years, and 49.7% had had a diagnosis of hypertension for more than 10 years. Eighty-nine percent of patients had some form of medical insurance. All patients had seen their family physician providers at least once within the past year. Seventy-seven percent of patients reported high adherence as measured by the Morisky scale. On multiple logistic regression, being older than 55, taking more than 7 prescribed medications, and having a lifestyle that included regular exercise or a healthy diet with low salt intake or both were significant independent predictors of high adherence scores on the Morisky scale (P ≤ .05). CONCLUSION: More than three-quarters of patients with type 2 DM and hypertension from community family practice clinics in Maritime Canada reported high adherence to their antihypertensive medications. Family physicians and nurse practitioners can apply strategies to improve antihypertensive medication adherence among type 2 DM patients who are younger, taking fewer medications, or not maintaining a lifestyle that includes regular exercise or a healthy diet or both. Future studies will need to determine whether focusing adherence strategies on these patients will improve their cardiovascular outcomes.

Assessing the feasibility of extracting clinical information to create quality indicators from primary healthcare practice EMRs.

In 2011, a panel of primary healthcare (PHC) providers in Nova Scotia rated 19 of 35 selected Canadian Institute for Health Information (2006) clinical quality indicators (QIs) as "acceptable." In this study, the authors explored the feasibility of extracting electronic medical record (EMR) data required to create these PHC QI measures.

Balanced crystalloids (RInger's lactate) versus normal Saline in adults with diabetic Ketoacidosis in the Emergency Department (BRISK-ED): a protocol for a pilot randomized controlled trial.

BACKGROUND: Current guidelines for diabetic ketoacidosis (DKA) recommend treatment with normal saline (NS). However, NS, with its high chloride concentrations, may worsen acidosis and contribute to a hyperchloremic metabolic acidosis. Alternatives to NS are balanced crystalloids (e.g. Ringer's Lactate [RL]) which have chloride concentrations similar to human plasma; therefore, treatment with balanced crystalloids may lead to faster DKA resolution. A recent systematic review and meta-analysis by Catahay et al. (2022) demonstrated the need for more blinded, high-quality trials comparing NS versus RL in the treatment of DKA. METHODS: We describe a protocol for BRISK-ED (Balanced crystalloids [RInger's lactate] versus normal Saline in adults with diabetic Ketoacidosis in the Emergency Department). Our study is a single-centre, triple-blind, pilot randomized controlled trial (RCT) of adults (≥ 18 years) with DKA presenting to an academic tertiary care ED in London, Canada. Patients with clinical suspicion for DKA will be screened and those found to not meet DKA criteria or have euglycemic DKA will be excluded. We will aim to recruit 52 patients with DKA and will randomize them 1:1 to receive intravenous RL or NS. The primary feasibility outcome will be recruitment rate, and the primary efficacy outcome will be time elapsed from ED presentation to DKA resolution. Secondary outcomes include time to insulin infusion discontinuation, intensive care unit admission, in-hospital death, and major adverse kidney events within 30 days, defined as a composite of: i) death, ii) new renal replacement therapy, or iii) final serum creatinine ≥ 200% baseline at the earliest of hospital discharge or 30 days after ED presentation. Patients, clinicians, and outcome assessors will be blinded to allocation group. We will follow an intention-to-treat analysis. Gehan-Wilcoxon, Mann-Whitney U, or chi-square tests will be used to compare groups as appropriate. DISCUSSION: The results of this pilot study will inform the design and feasibility of a full-scale, multicentre RCT to assess fluid choice in adult ED patients with DKA. If proven to demonstrate faster resolution of DKA, administration of balanced crystalloids may replace NS in diabetes treatment guidelines and improve patient and health systems outcomes.

Provision of immobilization or ice by paramedics in Southwestern Ontario.

OBJECTIVES: Pain is the most common reason for prehospital transport. As emergency wait times increase, timely pain management is essential. In children, there is abundant evidence that prehospital pharmacologic analgesia is suboptimal, but little is known about non-pharmacologic therapies. We sought to characterize documentation by paramedics of non-pharmacologic (immobilization and ice) and pharmacologic analgesia in children with musculoskeletal injuries. METHODS: We reviewed all ambulance call reports for children 0-17 years transported to Southwestern Ontario regional hospitals from January 1, 2017, to December 31, 2019, with a musculoskeletal injury (Ontario Ministry of Health and Long-Term Care problem codes 66 and 67). Primary and secondary outcomes were documented immobilization or ice and pharmacologic analgesia, respectively. In a multivariable analysis, we explored the relationship between immobilization or ice and the following a priori covariates: age, sex, visible deformity, crew type, pain severity, and analgesia. RESULTS: Of 40,692 ambulance call reports reviewed, 4445 met inclusion criteria. There were 2584/4441 (58.2%) males, with a median (IQR) age of 14 (10, 16) years. In ambulance call reports with documented pain scores, 2106/3048 (69.1%) ambulance call reports reported "moderate or severe" pain. Immobilization or ice were documented in 1605/4445 (36.1%) and 385/4445 (8.7%) of ambulance call reports. Pharmacologic analgesia was documented in 275/1983 (13.9%) and 125/991 (12.6%) of ambulance call reports for primary care paramedics and advanced care paramedics, respectively. An increased odds of documented immobilization or ice was associated with moderate or severe pain [OR: 2.4; 95% CI 1.84-3.17; p < 0.01] and visible deformity [OR: 2.5; 95% CI 1.97-3.12; p < 0.01]. CONCLUSIONS: Documented immobilization and ice and pharmacologic analgesia to children by paramedics is suboptimal. Our findings underscore an important need for enhanced education surrounding the benefits of non-pharmacologic options for children with musculoskeletal injuries.

RéSUMé: OBJECTIFS: La douleur est le motif le plus fréquent de transport préhospitalier. À mesure que les temps d'attente aux urgences augmentent, la gestion de la douleur en temps opportun est essentielle. Chez les enfants, il existe de nombreuses preuves que l'analgésie pharmacologique préhospitalière est sous-optimale, mais on sait peu de choses sur les thérapies non pharmacologiques. Nous avons cherché à caractériser la documentation par les ambulanciers paramédicaux de l'analgésie non pharmacologique (immobilisation et glace) et pharmacologique chez les enfants souffrant de lésions musculo-squelettiques. MéTHODES: Nous avons examiné tous les rapports d'appels d'ambulance pour les enfants de 0 à 17 ans transportés vers les hôpitaux régionaux du Sud-Ouest de l'Ontario du 1er janvier 2017 au 31 décembre 2019, avec une blessure musculo-squelettique (codes de problèmes 66 et 67 du ministère de la Santé et des Soins de longue durée de l'Ontario). Les résultats primaires et secondaires étaient l'immobilisation documentée ou la glace et l'analgésie pharmacologique, respectivement. Dans une analyse multivariable, nous avons exploré la relation entre l'immobilisation ou la glace et les covariables a priori suivantes: âge, sexe, déformation visible, type d'équipage, intensité de la douleur et analgésie. RéSULTATS: Sur les 40 692 rapports d'appels d'ambulance examinés, 4 445 répondaient aux critères d'inclusion. Il y avait 2584/4441 (58,2 %) hommes, avec un âge médian (IQR) de 14 (10,16) ans. Dans les rapports d'appel d'ambulance avec des scores de douleur documentés, 2106/3048 (69,1 %) rapports d'appel d'ambulance ont signalé une douleur "modérée ou sévère". L'immobilisation ou la glace ont été documentées dans 1605/4445 (36,1 %) et 385/4445 (8,7 %) des rapports d'appel d'ambulance. L'analgésie pharmacologique a été documentée dans 275/1983 (13,9 %) et 125/991 (12,6 %) des rapports d'appel d'ambulance pour les ambulanciers de soins primaires et les ambulanciers de soins avancés, respectivement. Une probabilité accrue d'immobilisation documentée ou de glace était associée à une douleur modérée ou intense [OR: 2,4; IC à 95 %: 1,84-3,17; p < 0,01] et déformation visible [OR: 2,5; IC à 95 %: 1,97-3,12; p < 0,01]. CONCLUSIONS: L'immobilisation documentée et l'administration de glace et d'analgésie pharmacologique aux enfants par les ambulanciers est sous-optimale. Nos résultats soulignent le besoin important de renforcer l'éducation concernant les avantages des options non pharmacologiques pour les enfants souffrant de blessures musculo-squelettiques.

Hypertension and type 2 diabetes: what family physicians can do to improve control of blood pressure--an observational study.

BACKGROUND: The prevalence of type 2 diabetes is rising, and most of these patients also have hypertension, substantially increasing the risk of cardiovascular morbidity and mortality. The majority of these patients do not reach target blood pressure levels for a wide variety of reasons. When a literature review provided no clear focus for action when patients are not at target, we initiated a study to identify characteristics of patients and providers associated with achieving target BP levels in community-based practice. METHODS: We conducted a practice-based, cross-sectional observational and mailed survey study. The setting was the practices of 27 family physicians and nurse practitioners in 3 eastern provinces in Canada. The participants were all patients with type 2 diabetes who could understand English, were able to give consent, and would be available for follow-up for more than one year. Data were collected from each patient's medical record and from each patient and physician/nurse practitioner by mailed survey. Our main outcome measures were overall blood pressure at target (< 130/80), systolic blood pressure at target, and diastolic blood pressure at target. Analysis included initial descriptive statistics, logistic regression models, and multivariate regression using hierarchical nonlinear modeling (HNLM). RESULTS: Fifty-four percent were at target for both systolic and diastolic pressures. Sixty-two percent were at systolic target, and 79% were at diastolic target. Patients who reported eating food low in salt had higher odds of reaching target blood pressure. Similarly, patients reporting low adherence to their medication regimen had lower odds of reaching target blood pressure. CONCLUSIONS: When primary care health professionals are dealing with blood pressures above target in a patient with type 2 diabetes, they should pay particular attention to two factors. They should inquire about dietary salt intake, strongly emphasize the importance of reduction, and refer for detailed counseling if necessary. Similarly, they should inquire about adherence to the medication regimen, and employ a variety of patient-oriented strategies to improve adherence.

Self-reported health beliefs, lifestyle and health behaviours in community-based patients with diabetes and hypertension.

OBJECTIVE: This study describes self-reported health and lifestyle behaviours and health risk beliefs among community patients diagnosed with type 2 diabetes and hypertension. METHODS: Patients with both type 2 diabetes and hypertension were recruited from community family practices across 3 Canadian Maritime provinces. Patients completed a survey targeting health risk beliefs, and health and lifestyle behaviours. Analyses examined differences in patient beliefs by age and sex, as well by health and lifestyle behaviour. RESULTS: Overall, 90.8% of patients believed that controlling both blood pressure and blood glucose were important, particularly women (p<0.01), and 92.8% felt that having both conditions put them at high risk for cardiovascular problems. Older patients reported higher antihypertensive medication adherence (p<0.0001). Most (90.8%) believed that prescription drug use was most helpful for controlling blood pressure, and this belief was associated with medication adherence (p<0.0001). Overall, patients who believed in the benefits of a given lifestyle behaviour were more likely to demonstrate the behaviour. CONCLUSION: The majority of patients surveyed were knowledgeable about their increased risk for cardiovascular problems. Patient lifestyle behaviours tended to mirror their health beliefs. These results provide important insight into the health beliefs and lifestyle behaviours of patients who receive the majority of their care in the community.

Do Adult Patients With Type 1 or 2 Diabetes Who Present to the Emergency Department With Hyperglycemia Have Improved Outcomes if They Have Access to Specialized Diabetes Care?

OBJECTIVES: Few studies have examined the effect of specialized care on patients with diabetes who present to the emergency department (ED) visits for acute hyperglycemia. The objective of this study was to characterize ED patients presenting with hyperglycemia and compare the 30-day outcomes of those followed by specialized diabetes clinics with those not followed. We hypothesized that patients followed by specialized clinics would have improved clinical outcomes compared with those who had no specialized follow up. METHODS: We conducted this single-centre retrospective cohort study of adults (≥18 years) with an ED visit for hyperglycemia over 1 year (January to December 2014). Data from ED visits were linked to specialized diabetes clinic records, which contained diabetes-specific clinical data not available in ED visit records. Descriptive statistics were summarized and comparisons between groups were performed, when appropriate. RESULTS: There were 456 patients (55.0% men; mean age, 47.7 years; 46.3% with type 1 diabetes) with 250 followed by the specialized diabetes clinics. The 206 patients who were not followed by the diabetes clinics (45%) were more likely to have a recurrent hyperglycemia ED visit (32.5% vs 9.6%, p<0.001) and to require hospitalization for hyperglycemia (14.1% vs 5.2%, p=0.001) within 30 days of initial presentation. CONCLUSIONS: Patients followed by specialized diabetes clinics had fewer recurrent ED visits and hospital admissions for hyperglycemia at 30 days compared with those not followed, suggesting that greater continuity of care between endocrinology and emergency medicine may help reduce these adverse outcomes for patients with diabetes.

Does utilization of an intubation safety checklist reduce omissions during simulated resuscitation scenarios: a multi-center randomized controlled trial.

OBJECTIVES: Checklists have been used to decrease adverse events associated with medical procedures. Simulation provides a safe setting in which to evaluate a new checklist. The objective of this study was to determine if the use of a novel peri-intubation checklist would decrease practitioners' rates of omission of tasks during simulated airway management scenarios. METHODS: Fifty-four emergency medicine (EM) practitioners from two academic centers were randomized to either their usual approach or use of our checklist, then completed three simulated airway management scenarios. A minimum of two assessors documented the number of tasks omitted and the time until definitive airway management. Discrepancies between assessors were resolved by single assessor video review. Participants also completed a post-simulation survey. RESULTS: The average percentage of omitted tasks over three scenarios was 45.7% in the control group (n = 25) and 13.5% in the checklist group (n = 29)-an absolute difference of 32.2% (95% CI 27.8, 36.6%). Time to definitive airway management was longer in the checklist group in the first two of three scenarios (difference of 110.0 s, 95% CI 55.0 to 167.0; 83.0 s, 95% CI 35.0 to 128.0; and 36.0 s, 95% CI -18.0 to 98.0 respectively). CONCLUSIONS: In this dual-center, randomized controlled trial, use of an airway checklist in a simulated setting significantly decreased the number of important airway tasks omitted by EM practitioners, but increased time to definitive airway management.

RéSUMé: OBJECTIFS: Des listes de contrôle ont été utilisées pour réduire les événements indésirables associés aux procédures médicales. La simulation offre un cadre sûr pour évaluer une nouvelle liste de contrôle. L'objectif de cette étude était de déterminer si l'utilisation d'une nouvelle liste de contrôle de péri-intubation permettrait de réduire les taux d'omission de tâches des praticiens lors de scénarios de gestion des voies aériennes simulés. MéTHODES: Cinquante-quatre praticiens de médecine d'urgence de deux centres universitaires ont été randomisés selon leur approche habituelle ou l'utilisation de notre liste de contrôle, puis ont réalisé trois scénarios de gestion des voies aériennes simulés. Un minimum de deux évaluateurs ont documenté le nombre de tâches omises et le délai avant la gestion définitive des voies respiratoires. Les divergences entre les évaluateurs ont été résolues par la revue vidéo d'un seul évaluateur. Les participants ont également rempli une enquête post-simulation. RéSULTATS: Le pourcentage moyen de tâches omises sur trois scénarios était de 45,7 % dans le groupe témoin (n = 25) et de 13,5 % dans le groupe liste de contrôle (n = 29) - une différence absolue de 32,2 % (IC à 95 %: 27,8 %, 36,6 %). Le délai de prise en charge définitive des voies respiratoires était plus long dans le groupe liste de contrôle dans les deux premiers des trois scénarios (différence de 110,0 s, IC à 95% : 55,0 à 167,0 ; 83,0 s, IC à 95 % : 35,0 à 128,0 ; et 36,0 s, IC à 95 % : -18,0 à 98,0 respectivement). CONCLUSIONS: Dans cet essai contrôlé randomisé à double centre, l'utilisation d'une liste de contrôle des voies respiratoires dans un environnement simulé a considérablement réduit le nombre de tâches importantes des voies respiratoires omises par les praticiens de médecine d'urgence, mais a prolongé le délai de prise en charge définitive des voies aérienne.
