Investigating Weekend Effect in the Management of Upper and Lower Extremity Degloving Injuries

Background

Weekend presentation has been associated with adverse outcomes in emergent conditions, including stroke, myocardial infarction, and critical limb ischemia. We examine whether a weekend effect exists in the management of and outcomes after extremity degloving injuries.

Methods

The cohort included adults presenting with open extremity degloving injuries to a tertiary level one trauma center between June 2018 and May 2022. We collected demographics, comorbidities, injury information, interventions, and complications. Propensity score weighting was used to minimize confounding differences between those presenting on weekends (Sat-Sun) versus weekdays (Mon-Fri). Weighted regressions were used to examine differences in interventions by day of presentation. Multivariable weighted regressions accounting for differences in interventions received were used to examine whether weekend presentation was associated with amputation risk, complications, or functional deficits.

Results

Ninety-five patients with 100 open extremity degloving injuries were included. In total, 39% of injuries were weekend-presenting. There was a higher rate of noninsulin-dependent diabetes among patients presenting on weekends (P = 0.03). Weekend-presenting injuries had higher median Injury Severity Scores (P = 0.04). Propensity-weighted regression analysis revealed differences in interventions received on weekends, including lower rates of pedicled and free flaps and bone graft, and increased rates of negative-pressure wound therapy (P ≤ 0.02). Multivariable regression analysis revealed weekend presentation was a significant independent risk factor for amputation of the affected extremity [odds ratio 2.27, 95% CI (1.01-5.33), P = 0.05].

Conclusion

Weekend presentation may impact interventions received and amputation risk in patients presenting with open extremity degloving injuries.

Pediatric Status Epilepticus: Treat Early and Avoid Delays

Pediatric convulsive status epilepticus (cSE) is a neurologic emergency with potential for morbidity and mortality. Rapid treatment and escalation of therapies to achieve early seizure control is paramount in preventing complications and providing the best patient outcomes. Although guidelines recommend early treatment, cessation of out-of-hospital SE is undermined by treatment delay and inadequate dosing. Logistical challenges include prompt seizure recognition, first-line benzodiazepine (BZD) availability, comfort and expertise in administration of BZD, and timely arrival of emergency personnel. In-hospital, SE onset is additionally impacted by delays to first- and second-line treatment and availability of resources. This review presents an evidence-based, clinically oriented review of pediatric cSE, including its definitions and treatments. It provides evidence and rationale for timely treatment of first-line BZD treatment followed by prompt escalation to second-line antiseizure medication therapies for established SE. Treatment delays and barriers to care are discussed, with practical considerations for opportunities for areas of improvement in the initial treatment of cSE.

Mixed-methods pilot study exploring the influence of the novel Paediatric Anaesthetic Drug Solution tool on clinician cognitive load during simulated paediatric rapid sequence intubation in the emergency department

AIM

Rapid sequence intubation (RSI) in children is a low-incidence, high-risk event associated with cognitive overload and potential errors producing unfavourable outcomes. Cognitive aids, such as charts, algorithms and flow diagrams, are prompts that externalise and structure mental processes to reduce cognitive load, thereby reducing errors. The Paediatric Anaesthetic Emergency Drug Solution (PAEDS) approach combines a colour-coded chart and medication box with a simplified mathematical system of volume-based dosing; the effect of which on cognitive load during a simulated RSI has not previously been described.

METHODS

A randomised, cross-over trial was conducted with 26 multi-disciplinary emergency medicine clinicians (doctors and nurses) allocated to four groups, performing four high-fidelity RSI simulations, two mandating the use of the PAEDS approach. This mixed methods study followed the pragmatic ontology using grounded theory methodology. Qualitative data were collected from nine individual interviews by a process of thematic analysis via an inductive approach, to allow for appropriate open and axial coding to occur. Quantitative data collected included cognitive loading using the raw NASA-Task Load Index as well as time to intubation and drug dosage details to assess for safety.

RESULTS

Qualitative results showed that the PAEDS approach reduced cognitive loading through the use of both the labelled medication box and colour-coded medication charts. The PAEDS approach also showed improved perceived time pressure without feeling rushed, and with no recorded drug errors. Differences in the quantitative data for total cognitive load, error and time were not statistically significant, likely due to sample size.

CONCLUSION

The PAEDS approach is a multifaceted system which is not inferior to current practice, with some components described as an improvement. Further research on a larger sample size needs to be conducted to assess the aspects of the PAEDS approach both collectively and independently.

Factors Influencing Medication Errors in the Prehospital Paramedic Environment: A Mixed Method Systematic Review

INTRODUCTION

There is limited research available on safe medication management practices in EMS practice, with most evidence-based medication safety guidelines based on research in nursing, operating theatre and pharmacy settings. Prevention of errors requires recognition of contributing factors across the spectrum from the organizational level to procedural elements and patient characteristics. Evidence is inconsistent regarding the incidence of medication errors and multiple sources also state that errors are under-reported, making the true magnitude of the problem difficult to quantify. Definitions of error also vary, with the specific context of medication errors in prehospital practice yet to be established. The objective of this review is to identify the factors influencing the occurrence of medication errors by EMS personnel in the prehospital environment.

METHODS AND ANALYSIS

The review included both qualitative and quantitative research involving interventions or phenomena related to medication safety or medication error by EMS personnel in the prehospital environment. A search of multiple databases was conducted to identify studies meeting these inclusion criteria. All studies selected were assessed for methodological quality, however this was not used as a basis for exclusion. Each stage of study selection, appraisal and data extraction was conducted by two independent reviewers, with a third reviewer deciding any unresolved conflicts. The review follows a convergent integrated approach, conducting a single qualitative synthesis of qualitative and "qualitized" quantitative data.

RESULTS

56 articles were included in the review, with case reports and qualitative studies being the most frequent study types. Qualitative analysis revealed seven major themes: organizational factors (with reporting as a sub-theme), equipment/medications, environmental factors, procedure-related factors, communication, patient-related factors (with pediatrics as a sub-theme) and cognitive factors. Both contributing factors and protective factors were identified.

DISCUSSION

The body of evidence regarding medication errors is heterogenous and limited in both quantity and quality. Multiple factors influence medication errors occurrence; knowledge of these is necessary to mitigate the risk of errors. Medication error incidence is difficult to quantify due to inconsistent measure, definitions and contexts of research conducted to date. Further research is required to quantify the prevalence of identified factors in specific practice settings.

Optimized Benzodiazepine Treatment of Pediatric Status Epilepticus Through a Standardized Emergency Medical Services Resuscitation Tool

BACKGROUND

Optimized benzodiazepine (BZD) dosing decreases morbidity and mortality in children with status epilepticus (SE), but previous studies have documented widespread underdosing. Prior interventions have focused on in-hospital SE treatment, although more than 75% of pediatric patients with SE are initially treated by emergency medical services (EMS). Our goal was to assess whether an EMS-focused, collaboratively developed dosing resuscitation aid (Medic One Pediatric [MOPed] cards) and training could improve BZD dosing and pediatric SE outcomes.

METHODS

We conducted a retrospective review of patients aged 12 years and younger treated by EMS for SE and transferred to Seattle Children's Hospital during the 1 year before and immediately after MOPed card training. The primary outcome was the percentage of patients receiving underdosed BZD treatment. Secondary outcomes included time to second-line antiseizure medication (ASM), intubation, and intensive care unit (ICU) admission.

RESULTS

The 44 children before and 33 after MOPed implementation were similar with respect to age, gender, and pre-existing epilepsy diagnosis. The percentage of children receiving underdosed BZDs fell from 52% to 6% after MOPed implementation (P < 0.001). There was no significant decrease in requirement for intubation and ICU admission. The interval to treatment with a second-line ASM remained prolonged.

CONCLUSIONS

EMS-focused training significantly increased the percentage of outpatient pediatric patients with SE who received recommended initial BZD treatment. This improvement in management of SE did not significantly alter the rate of intubation or ICU admission, suggesting the need for further optimization of out-of-hospital SE care, particularly access to and timely use of second-line ASMs.
