Three are no clinical practice guidelines that specifically address the management of patients with iron deficiency anemia (IDA) in the emergency department (ED). The goal of this study was to describe the characteristics of IDA patients who present to the ED, documentation of IDA by emergency physicians, utilization of iron supplementation, and the appropriateness of red blood cell (RBC) transfusions ordered in the ED.

A retrospective medical chart review was performed of IDA patients who visited the ED of a large tertiary center over a three-month period. Appropriateness of RBC transfusion was determined using a novel algorithm developed by our institution.

Over the study period, there was a 0.3% (49/14,394) prevalence of IDA in the ED. In thirty (30/49; 61%) patients, IDA was documented by an emergency physician. RBC transfusions were administered to 19 patients; 10 transfusions (53%) were appropriate, 3 (16%) were appropriate for indication, but more than the required number of units were ordered, and 6 (32%) were inappropriate. Of the patients discharged, one (1/25; 4%) patient received intravenous iron in the ED and 6 of the 11 patients (55%) that were not already taking oral iron received a prescription at discharge from the ED.

This assessment demonstrated that management of IDA patients presenting to the ED may represent an important knowledge-to-practice gap. It revealed that RBC transfusion may be over-utilized and could be replaced by safer, lower-cost alternatives such as intravenous and oral iron. Guidelines for management of IDA in the ED may be necessary to achieve consistent IDA management and avoid inappropriate use of RBC transfusion.

We surveyed Canadian emergency physicians to determine how skin and soft tissue infections (SSTIs) are managed and which risk factors were felt to be important in predicting failure with oral antibiotics.

We performed an electronic survey of physician members of the Canadian Association of Emergency Physicians (CAEP) using the modified Dillman method.

The survey response rate was 36.9% (n=391) amongst CAEP members. There was a lack of consensus regarding management of SSTIs. CAEP respondents identified 14 risk factors for predicting treatment failure with oral antibiotics, including hypotension, tachypnea, and patient reported severity of pain >8 of 10.

The survey demonstrates significant variability regarding physician management of SSTIs, and we have identified several perceived risk factors for treatment failure with oral antibiotics that should be assessed in future studies.

Optic nerve sheath diameter (ONSD) measured on a head computed tomography (CT) has been suggested as a potential prognostic factor for poor neurological outcome after cardiac arrest. We performed a single centre retrospective cohort analysis to further investigate this relationship.

All patients >18 years of age admitted to St. Paul’s Hospital in Vancouver, Canada who survived a cardiac arrest and had a CT scan of the head within 48 hours were included in the analysis.

A total of 72 patients met inclusion criteria for the study; 54 (75.0%) of the patients had a poor neurological outcome, whereas 18 (25.0%) patients were discharged from the hospital with a good outcome. A CT head was obtained for patients in the good outcome group in a mean time of 9.3 hours (SD 10.0) compared to 10.2 hours (SD 11.2) for the poor outcome group (p=0.75). There was no difference in average ONSD observed between the two outcome groups (6.66 mm SD 0.78 v. 6.60 mm SD 0.82, p=0.77). Multiple logistic regression failed to show any association between ONSD and neurological outcome when adjusted for all other covariates (OR 1.32 95% CI 0.40-4.34, p=0.65). Setting an ONSD threshold of >8 mm (OR 2.32, 95% CI 0.14-39.40, p=0.55) or >7 mm (OR 0.28, 95% CI 0.03-2.77, p=0.28) also failed to show any association on neurological outcome.

There was no observed difference in ONSD between those with a good neurological outcome and those with a poor outcome. ONSD was not an independent predictor of poor neurological outcome.

Various medications and devices are available for facilitation of emergent endotracheal intubations (EETIs). The objective of this study was to survey which medications and devices are being utilized for intubation by Canadian physicians.

A clinical scenario-based survey was developed to determine which medications physicians would administer to facilitate EETI, their first choice of intubation device, and backup strategy should their first choice fail. The survey was distributed to Canadian emergency medicine (EM) and intensive care unit (ICU) physicians using web-based and postal methods. Physicians were asked questions based on three scenarios (trauma; pneumonia; heart failure) and responded using a 5-point scale ranging from “always” to “never” to capture usual practice.

The survey response rate was 50.2% (882/1,758). Most physicians indicated a Macintosh blade with direct laryngoscopy would “always/often” be their first choice of intubation device in the three scenarios (mean 85% [79%-89%]) followed by video laryngoscopy (mean 37% [30%-49%]). The most common backup device chosen was an extraglottic device (mean 59% [56%-60%]). The medications most physicians would “always/often” administer were fentanyl (mean 45% [42%-51%]) and etomidate (mean 38% [25%-50%]). EM physicians were more likely than ICU physicians to paralyze patients for EETI (adjusted odds ratio 3.40; 95% CI 2.90-4.00).

Most EM and ICU physicians utilize direct laryngoscopy with a Macintosh blade as a primary device for EETI and an extraglottic device as a backup strategy. This survey highlights variation in Canadian practice patterns for some aspects of intubation in critically ill patients.

Pediatric acute gastroenteritis (AGE) is a common condition with high health care utilization, persistent practice variation, and substantial family burden. An initial approach to resolve these issues is to understand the patient/caregiver experience of this illness. The objective of this study was to describe caregivers’ experiences of pediatric AGE and identify their information needs, preferences, and priorities.

A qualitative, descriptive study was conducted. Caregivers of a child with AGE were recruited for this study in the pediatric emergency department (ED) at a tertiary hospital in a major urban centre. Individual interviews were conducted (n=15), and a thematic analysis of interview transcripts was completed using a hybrid inductive/deductive approach.

Five major themes were identified and described: 1) caregiver management strategies; 2) reasons for going to the ED; 3) treatment and management of AGE in the ED; 4) caregivers’ information needs; and 5) additional factors influencing caregivers’ experiences and decision-making. A number of subthemes within each major theme were identified and described.

This qualitative descriptive study has identified caregiver information needs, preferences, and priorities regarding pediatric AGE. This study also identified inconsistencies in the treatment and management of pediatric AGE at home and in the ED that influence health care utilization and patient outcomes related to pediatric AGE.

Patients who are tobacco users present to the emergency department (ED) with many medical conditions that are causally or potentially causally related to smoking. Previous studies have shown increased cessation rates for patients who accurately perceive that their ED visit is smoking-related. Our study goals were 1) to determine the prevalence of potential smoking-related conditions among tobacco users at a tertiary care academic ED, and 2) to determine which medical conditions are more or less likely to be perceived by patients as smoking-related.

We included adults≥19 years of age who reported smoking within 30 days of their ED visit, and were enrolled in a randomized controlled trial (ClinicalTrials.gov, NCT01454375) from December 1, 2011 to August 31, 2012. Patients were asked whether they perceived their ED visit to be related to smoking. ED discharge diagnoses were coded as smoking-related or not smoking-related based on the 2004 U.S. Surgeon General’s Report.

We included 893 patients (62% male; mean age=40±15), of which 120 (13%) had a visit for a potential smoking-related condition: 6 (5%) of neoplasm, 18 (15%) of cardiovascular disease, 67 (56%) of respiratory disease, 3 (3%) of reproductive complication, 7 (6%) of postoperative complication, 9 (8%) of dental disease, 9 (8%) of peptic ulcer disease, 0 (0%) of eye condition, and 1 (1%) of bony condition. Of the potential smoking-related conditions, 46 (38%) were perceived by patients to be possibly smoking-related: 61% of cardiovascular disease, 33% of neoplasm, 43% of respiratory disease, 22% of dental disease, 14% of postoperative complication, 11% of peptic ulcer disease, and 0% of the remaining conditions.

In this study, 13% of all ED visits among smokers were for a potential smoking-related condition, of which 38% were perceived by patients to be smoking-related. Education to increase awareness of smoking-related conditions may increase cessation rates.

The main objective of this study was to evaluate the feasibility of emergency department (ED) point-of-care ultrasound (PoCUS) for rib fracture diagnosis in patients with minor thoracic injury (mTI). Secondary objectives were to 1) evaluate patients’ pain during the PoCUS procedure, 2) identify the limitations of the use of PoCUS technique, and 3) compare the diagnosis obtained with PoCUS to radiography results.

Adult patients who presented with clinical suspicion of rib fractures after mTI were included. All patients underwent PoCUS performed by emergency physicians (EPs) prior to a rib view X-ray. A visual analogue scale (VAS) ranging from 0 to 100 was used to ascertain feasibility, patients’ pain and clinicians’ degree of certitude. Feasibility was defined as a score of more than 50 on the VAS. We documented the radiologists’ interpretation of rib view X-ray. Radiologists were blinded to the PoCUS results.

Ninety-six patients were included. A majority (65%) of EPs concluded that the PoCUS technique to diagnose rib fracture was feasible (VAS score > 50). Median score for feasibility was 63. Median score was 31 (Interquartile range [IQR] 5–57) for patients’ pain related to the PoCUS. The main limiting factor of the PoCUS technique was pain during patient examination (15%).

PoCUS examination appears to be a feasible technique for a rib fracture diagnosis in the ED.
