Numerous studies reported on the frequency of, and factors associated with inappropriate or unnecessary emergency department (ED) visits using clinician judgment as the gold standard of appropriateness. This study evaluated the reliability of clinician judgment for assessing appropriateness of pediatric ED visit.

We conducted a retrospective cohort study comparing 3 clinicians’ determination of ED visit appropriateness with and without guidance from a three-question structured algorithm. We used a cohort of scheduled ED return visits deemed appropriate by the index treating clinician between May 1, 2012, and April 30, 2013. We measured the level of agreement among three clinician investigators with and without use of the structured algorithm.

A total of 207 scheduled ED return visits were reviewed by the primary clinician reviewer who agreed with the index treating clinician for 79/207 visits (38.2%). Among a random subset of 90 return visits reviewed by all three clinicians, agreement was 67% with a Fleiss’ Kappa of 0.30 (0.17–0.44). Using a three-question algorithm based on objective criteria, agreement with the index treating provider increased to 115/207 (55.6%).

Although an important contributor to pediatric ED overcrowding, unnecessary or inappropriate visits are difficult to identify. We demonstrated poor reliability of clinician judgment to determine appropriateness of ED return visits, likely due to variability in clinical decision-making and risk-tolerance, social and systems factors impacting access and use of health care. We recommend that future studies evaluating the appropriateness of ED use standardized, objective criteria rather than clinician judgment alone.

Cricothyrotomy is an intervention performed to salvage “can't intubate, can't ventilate” situations. Studies have shown poor accuracy with landmarking the cricothyroid membrane, particularly in female patients by surgeons and anesthesiologists. This study examines the perceived versus actual success rate of landmarking the cricothyroid membrane by resident and staff emergency physicians using obese and non-obese models.

Five male and female volunteers were models. Each model was placed supine, and a point-of-care ultrasound expert landmarked the borders of each cricothyroid membrane; 20 residents and 15 staff emergency physicians were given one attempt to landmark five models. Overall accuracy and accuracy stratified by sex and obesity status were calculated.

Overall landmarking accuracy amongst all participants was 58% (SD 18%). A difference in accuracy was found for obese males (88%) versus obese females (40%) (difference = 48%, 95% CI = 30–65%, p < 0.0001), and non-obese males (77%) versus non-obese females (46%) (difference = 31%, 95% CI = 12–51%, p = 0.004). There was no association between perceived difficulty and success (correlation = 0.07, 95% CI = −0.081–0.214, p = 0.37). Confidence levels overall were higher amongst staff physicians (3.0) than residents (2.7) (difference = 0.3, 95% CI = 0.1–0.6, p = 0.02), but there was no correlation between confidence in an attempt and its success (p = 0.33).

We found that physicians demonstrate significantly lower accuracy when landmarking cricothyroid membranes of females. Emergency physicians were unable to predict their own accuracy while landmarking, which can potentially lead to increased failed attempts and a longer time to secure the airway. Improved training techniques may reduce failed attempts and improve the time to secure the airway.

Our objective was to examine the performance characteristics of a bladder stimulation technique for urine collection among infants presenting to the emergency department (ED).

This prospective cohort study enrolled a convenience sample of infants aged ≤ 90 days requiring urine testing in the ED. Infants were excluded if critically ill, moderately to severely dehydrated, or having significant feeding issues. Bladder stimulation consisted of finger tapping on the lower abdomen with or without lower back massage while holding the child upright. The primary outcome was successful midstream urine collection within 5 minutes of stimulation. Secondary outcomes included sample contamination, bladder stimulation time for successful urine collection, and perceived patient distress on a 100-mm visual analog scale (VAS).

We enrolled 151 infants and included 147 in the analysis. Median age was 53 days (interquartile range [IQR] 27–68 days). Midstream urine sample collection using bladder stimulation was successful in 78 infants (53.1%; 95% confidence interval [CI] 45–60.9). Thirty-nine samples (50%) were contaminated. Most contaminated samples (n = 31; 79.5%) were reported as “no significant growth” or “growth of 3 or more organisms”. Median bladder stimulation time required for midstream urine collection was 45 seconds (IQR 20–120 seconds). Mean VAS for infant distress was 22 mm (standard deviation 23 mm).

The success rate of this bladder stimulation technique was lower than previously reported. The contamination rate was high, however most contaminated specimens were easily identified and had no clinical impact.

Acquired methemoglobinemia (MetHb) is an uncommon presentation of cyanosis in the pediatric emergency department (ED), making its diagnosis and management a clinical challenge. Through this case series we hope to improve clinician ability to recognize the potential for MetHb in pediatric ED patients and to avoid overlooking this important cause of cyanosis.

This was a case series using a health records review, investigating patients diagnosed with MetHb at our pediatric ED during 2007–2018. We included only cases with methemoglobin saturation ≥5%.

Ten patients were diagnosed with MetHb in our pediatric ED during the study period. Five had an underlying hematologic disease who received a pharmacologic trigger known to induce MetHb as well (four dapsone, one rasburicase). The other five patients were previously healthy, who presented with a clinical picture of hemolytic anemia, all of whom were diagnosed with previously unknown glucose-6-phosphate dehydrogenase (G6PD) deficiency. Two of the patients received methylene blue, and five patients needed packed red blood cells. All of the patients survived the acute MetHb episode.

Acquired MetHb in the pediatric ED is a rare but important cause of cyanosis. Diagnosis and management of acute, acquired MetHb in the ED requires a high level of suspicion, and a background knowledge of the common precipitants and underlying conditions associated with this condition. We hope this case series will help ED physicians to consider MetHb in pediatric patients presenting with cyanosis and persistent hypoxia. Exposure to known precipitants (e.g., medications and foods), particularly in the setting of active treatment for malignancy or with symptoms of hemolytic anemia should further increase suspicion.

Routine coagulation testing is rarely indicated in the emergency department. Our goal is to determine the combined effects of uncoupling routine coagulation testing (i.e., international normalized ratio [INR]; activated partial thromboplastin time [aPTT]), disseminating an educational module, and implementing a clinical decision support system (CDSS) on coagulation testing rates in two academic emergency departments.

A prospective pre-post study of INR-aPTT uncoupling, educational module distribution, and CDSS implementation in two academic emergency departments. All patients ages 18 years and older undergoing evaluation and treatment during the period of August 1, 2015, to November 30, 2017, were included. Primary outcome was coagulation testing utilization during the emergency department encounter. Secondary outcomes included associated costs, frequency of downstream testing, and frequency of blood transfusions.

Uncoupling INR-aPTT testing combined with educational module distribution and CDSS implementation resulted in significantly decreased coupled INR-aPTT testing, with significantly increased selective INR and aPTT testing. Overall, the aggregate rate of coagulation testing declined for both INR and aPTT testing (48 tests/100 patients/day to 26 tests/100 patients/day). There was a significant decrease in associated daily costs (median cost per day: $1048.32 v. $601.68), realizing estimated annual savings of $163,023 Canadian dollars (CAD). There was no signal of increased downstream testing or patient blood product requirements.

Compared to baseline practice patterns, our multimodal initiative significantly decreased coagulation testing, with meaningful cost savings and without evidence of patient harm. Clinicians and administrators now have a growing toolkit to target the plethora of low-value tests and treatments in emergency medicine.

Audit and feedback is widely used to improve physician performance. Many data metrics are being provided to physicians, yet most of these are driven by the regulatory environment. We sought to conduct a needs assessment of audit and feedback metrics that were most useful to clinicians within our health care region.

We conducted a Web-based survey of five clinical practice sites in our region and asked that physicians rank 49 clinical practice metrics. In addition, we assessed their readiness for audit and feedback and their preferences for data confidentiality. We collected data on duration of training, gender, and site of practice (academic v. community) allowing for comparison between groups.

A total of 104 emergency medicine physicians participated in the survey (52.3% response rate). There was a significant readiness for participation in audit and feedback activities. Top ranked metrics were emergency department return rates and colleague's assessment of collegiality and quality of care, which were common across all sites. Small yet significant differences were noted between genders and academic v. community practitioners.

This study represents the first regional analysis of physician preferences for audit and feedback activities and implementation. It demonstrates that physicians are interested in audit and feedback activities and provides a roadmap for the development of a regional audit and feedback structure. It will also be used as a guiding document for regional change management.
