Color-Coded Prefilled Medication Syringes Decrease Time to Delivery and Dosing Error in Simulated Emergency Department Pediatric Resuscitations

Fixed dose ketamine for prehospital management of hyperactive delirium with severe agitation

INTRODUCTION

Patients exhibiting signs of hyperactive delirium with severe agitation (HDSA) may require sedating medications for stabilization and safe transport to the hospital. Determining the patient's weight and calculating the correct weight-based dose may be challenging in an emergency. A fixed dose ketamine protocol is an alternative to the traditional weight-based administration, which may also reduce dosing errors. The objective of this study was to evaluate the frequency and characteristics of adverse events following pre-hospital ketamine administration for HDSA.

METHODS

Emergency Medical Services (EMS) records from four agencies were searched for prehospital ketamine administration. Cases were included if a 250 mg dose of ketamine was administered on standing order to an adult patient for clinical signs consistent with HDSA. Protocols allowed for a second 250 mg dose of ketamine if the first dose was not effective. Both the 250 mg initial dose and the total prehospital dose were analyzed for weight based dosing and adverse events.

RESULTS

Review of 132 cases revealed 60 cases that met inclusion criteria. Patients' median weight was 80 kg (range: 50-176 kg). No patients were intubated by EMS, one only requiring suction, three required respiratory support via bag valve mask (BVM). Six (10%) patients were intubated in the emergency department (ED) including the three (5%) supported by EMS via BVM, three (5%) others who were sedated further in the ED prior to requiring intubation. All six patients who were intubated were discharged from the hospital with a Cerebral Performance Category (CPC) 1 score. The weight-based dosing equivalent for the 250 mg initial dose (OR: 2.62, CI: 0.67-10.22) and the total prehospital dose, inclusive of the 12 patients that were administered a second dose, (OR: 0.74, CI: 0.27, 2.03), were not associated with the need for intubation.

CONCLUSION

The 250 mg fixed dose of ketamine was not >5 mg/kg weight-based dose equivalent for all patients in this study. Although a second 250 mg dose of ketamine was permitted under standing orders, only 12 (20%) of the patients were administered a second dose, none experienced an adverse event. This indicates that the 250 mg initial dose was effective for 80% of the patients. Four patients with prehospital adverse events likely related to the administration of ketamine were found. One required suction, three (5%) requiring BVM respiratory support by EMS were subsequently intubated upon arrival in the ED. All 60 patients were discharged from the hospital alive. Further research is needed to determine an optimal single administration dose for ketamine in patients exhibiting signs of HDSA, if employing a standardized fixed dose medication protocol streamlines administration, and if the fixed dose medication reduces the occurrence of dosage errors.

Is there evidence that length-based tapes with precalculated drug doses increase the accuracy of drug dose calculations in children? A systematic review

OBJECTIVE

The use of pediatric length-based weight estimation tapes with precalculated drug doses is advocated by major Advanced Life Support organizations, but concerns have been raised on the accuracy of these systems. The objective of this systematic review was to collect, review, evaluate, and create a synthesis of the current literature to establish whether there is high-quality evidence for use of length-based tapes in accurate drug dose administration. A further objective was to compare these tapes with other dosing aids.

METHODS

Eligible studies were identified and analyzed if they were peer reviewed, full text articles containing original data. Studies including any form of length-based precalculated drug dosing methodology in children aged 0 to 18 years were included.

RESULTS

Eighteen studies met the inclusion criteria. The most studied of the tapes was the Broselow tape in 16 studies (88.9%). When these tapes were used on their own without additional reference material, they produced a substantial number of potentially harmful dosing errors (>20% error). No tape was superior to another. Using the tapes was better than using no dosing aid but was inferior to using both comprehensive drug dosing guides and novel color-coded medication administration systems.

CONCLUSION

There was no high-quality evidence that the use of length-based tapes with precalculated drug doses leads to accurate drug dosing. However, comprehensive drug dosing systems were more effective at reducing dosing errors than were length-based tapes on their own. The confounding effect of weight estimation accuracy on drug dosing accuracy has not been sufficiently studied.

Preparation/administration of push-dose versus continuous infusion epinephrine and phenylephrine: A simulation

BACKGROUND

Hypotension is a common problem in the emergency department (ED) and intensive care unit (ICU) and can increase risk for poor outcomes. Many EDs/ICUs utilize epinephrine and phenylephrine to treat hypotension and these medications are most often administered as a continuous infusion (CI). Push-dose (PD) is the administration of small medication doses as intermittent intravenous pushes (IVPs). There is limited information comparing the time required to prepare and administer PD versus CI and errors have been reported when preparing and administering these medications at bedside. This simulation study sought to estimate preparation and administration times and preparation and errors with PD and CI epinephrine and phenylephrine when prepared by an ED/ICU pharmacist.

METHODS

This crossover simulation study took place in a simulation center at an academic medical center and utilized a multi-venous intravenous training arm kit equip with an 18-gauge intravenous line, an extension tubing set, and a luer-lock adapter. The primary outcome was total preparation and administration time in seconds. The secondary outcome was major preparation and administration errors, defined as errors causing a five-fold or greater overdose.

RESULTS

In total, 16 pharmacists participated, including nine ED and seven ICU pharmacists. PD had faster total preparation and administration time and administration time, but not preparation time; PD showed an approximate 70 s decrease in total preparation and administration time versus CI. PD had more major preparation and administration errors and six PD preparations (18.8%, 6/32) had at least one major preparation and administration error. CI, on the other hand, had no major preparation and administration errors.

DISCUSSION

This simulation found faster total preparation and administration time with PD versus CI epinephrine and phenylephrine, but also found that PD had more major preparation and administration errors. Dilutional errors during medication preparation were the cause of 83.3% (5/6) of our overdoses.

CONCLUSION

This simulation study showed that ED/ICU pharmacists had faster median total preparation and administration times for PD epinephrine and phenylephrine versus CI, but PD also had more preparation and administration errors.

Creating an evidence-based economic model for prefilled parenteral medication delivery in the hospital setting

OBJECTIVES

Prefilled syringes (PFS) may offer clinical and economic advantages over conventional parenteral medication delivery methods (vials and ampoules). The benefits of converting from vials and ampoules to PFS have been explained in previous drug-specific economic models; however, these models have limited generalisability to different drugs, healthcare settings and other countries. Our study aims to (1) present a comprehensive economic model to assess the impact of switching from vials to PFS delivery; and (2) illustrate through two case studies the model's utility by highlighting important features of shifting from vials to PFS.

METHODS

The economic model estimates the potential benefit of switching to PFS associated with four key outcomes: preventable adverse drug events (pADE), preparation time, unused drugs, and cost of supplies. Model reference values were derived from existing peer-reviewed literature sources. The user inputs specific information related to the department, drug, and dose of interest and can change reference values. Two hypothetical case studies are presented to showcase model utility. The first concerns a cardiac intensive care unit in the United Kingdom administering 30 doses of 1 mg/10 mL atropine/day. The second concerns a coronavirus (COVID-19) intensive care unit in France that administers 30 doses of 10 mg/25 mL ephedrine/day.

RESULTS

Total cost savings per hospital per year, associated with reductions in pADEs, unused drugs, drug cost and cost of supplies were £34 829 for the atropine example and €104 570 for the ephedrine example. Annual preparation time decreased by 371 and 234 hours in the atropine and ephedrine examples, respectively.

CONCLUSIONS

The model provides a generalisable framework with customisable inputs, giving hospitals a comprehensive view of the clinical and economic value of adopting PFS. Despite increased costs per dose with PFS, the hypothetical case studies showed notable reductions in medication preparation time and a net budget savings owing to fewer pADEs and reduced drug wastage.

Nanoparticulate impurities in the pharmaceutical excipient trehalose induce an early immune response

BACKGROUND

Pharmaceutical excipients are an important part of biological products. However, few attempts have been made to distinguish between the risk of inflammation associated with the biological products themselves and that associated with excipients. The analysis of early immune response risk associated with excipients added to biological products is an important step in exploring the complex mechanism of side effects in susceptible patients.

METHODS AND RESULTS

In this study, nanoparticle impurities (NPIs) were extracted from trehalose and characterized. A mouse popliteal lymph node cell (PLNA) model, a mouse spleen lymphocyte model, a human peripheral blood mononuclear cell cytokine release model, and a macrophage complement activation model were established to comprehensively evaluate the early immune risk related to impurities in the trehalose excipient. Although popliteal lymph node cell counts in mice did not show significant differences, all other models indicated possible immune risk. In the PLNA model, NPIs caused significant toe thickening in mice, whereby the content of IgE and MCP-1 increased significantly. NPIs significantly increased the proliferation and differentiation of spleen lymphocytes according to the CCK-8 assay and flow cytometry. After treatment with NPIs, the release of IgE and a variety of cytokines (MIP-1α, IFN-γ, IL-2, IL-8, TNF-α, IL-6, IL-1α) in human peripheral blood cells was significantly increased according to ELISA, while a concomitant increase of C3a/C5a as well as C4a/Bb proved that NPIs activated the complement system.

CONCLUSION

NPIs from trehalose elicited an immune response in vitro, and the immune response to trehalose may be related to NPIs and not the excipient itself. Different batches of trehalose showed different immune response effects. The currents research suggests that when trehalose is applied in high-risk administration routes, NPIs should be assessed and reasonably controlled.

The influence of the simulation environment on teamwork and cognitive load in novice trauma professionals at the emergency department: Piloting a randomized controlled trial

INTRODUCTION

This pilot study aimed to test the feasibility of conducting a randomized controlled trial to examine how simulation environments (in situ versus laboratory) influence teamwork skills development and cognitive load among novice healthcare trauma professionals in the emergency department.

METHOD

Twenty-four novice trauma professionals (nurses, medical residents, respiratory therapists) were assigned to in situ or laboratory simulations. They participated in two 15-minute simulations separated by a 45-minute debriefing on teamwork. After each simulation, they completed validated teamwork and cognitive load questionnaires. All simulations were video recorded to assess teamwork performance by trained external observers. Feasibility measures (e.g., recruitment rate, randomization procedure and intervention implementation) were recorded. Mixed ANOVAs were used to calculate effect sizes.

RESULTS

Regarding feasibility, several difficulties were encountered, such as a low recruitment rate and the inability to perform randomization. Outcome results suggest that the simulation environment does not affect novice trauma professionals' teamwork performance and cognitive load (small effect sizes), but a large effect size was observed for perceived learning.

CONCLUSION

This study highlights several barriers to conducting a randomized study in the context of interprofessional simulation-based education in the emergency department. Suggestions are made to guide future research in the field.

Intravenous therapy device labeling in Intensive Care Units: an integrative review

OBJECTIVES

to synthesize the evidence on intravenous device labeling used to identify medications administered to patients in Intensive Care Units, with a view to preventing medication errors.

METHODS

an integrative review, in the LILACS, IBECS, Embase, MEDLINE, Scopus, Web of Science and CINAHL databases, from November to December 2021, using descriptors and selection criteria. Data were collected in 11 articles and subsequently classified, summarized and aggregated.

RESULTS

pre-designed labels, with pre-defined colors and information, help to prevent medication identification errors. There is still a lack of standardization in the practice of labeling syringes, intravenous lines, infusion pumps and saline solution bags. There are errors related to the lack of labeling devices or to their performance with incomplete information.

CONCLUSIONS

device labeling is a barrier to defending the medication system safety and should be standardized.

Conclusões: a rotulagem dos dispositivos é uma barreira para a defesa da segurança do sistema de medicação, devendo ser padronizada.

Comparison Between a Color-only Method and a Food and Drug Administration-approved Validation Method for a Pediatric Color-coded Syringe Using Midazolam: A Randomized Crossover Trial

OBJECTIVE

The objective of this study was to assess the use of a color-only method syringe for accuracy and timeliness when administrating midazolam. This method was compared with a U.S. Food and Drug Administration (FDA)-approved validation method.

METHODS

A prospective, randomized, crossover trial was conducted to compare the dosing accuracy and timeliness of the color-only syringe method versus the validation method. Twenty-five participants prepared pediatric midazolam doses according to their preferred method, a FDA-approved validation method, and a color-only method. Primary endpoints included dosing accuracy and time to medication administration.

RESULTS

The preferred 3-kg calculations had a median margin of error of 5.6% and a median time to completion of 55.6 seconds. The color-only method took less time to complete than the validation method (median time: 29.5 seconds vs 58.2 seconds). There was no statistically significant difference in errors between the color-only method and the validation method. None of the participants reported a mistake using the color-only method, whereas 25% (5/20) reported a mistake using the validation method. Only 20% (4/20) of participants believed that the validation method found or eliminated any mistakes. There were 8 medication errors identified when participants used the method of choice, 4 with the validation method, and 1 with the color-only method.

CONCLUSIONS

There was no significant difference in dosing errors between the FDA-approved validation method and the color-only method. Use of a color-only method did reduced time to medication administration when compared with a preferred method and an FDA-approved validation method.

Variation in Prehospital Protocols for Pediatric Seizure Within the United States

OBJECTIVE

The objective of this study was to compare statewide prehospital protocols for the management of pediatric seizures.

METHODS

We performed a descriptive analysis comparing statewide protocols for emergency medical services management of pediatric seizures within the United States, excluding states for which no statewide protocol/model was available. We compared antiepileptic drugs (AEDs), routes and doses of administration, and differences in febrile seizure management.

RESULTS

Of 50 states, 34 had either statewide protocols or models and were included. All had a protocol for the management of seizures and provided specific recommendations for the management of pediatric seizures. Twelve states (35%) preferentially recommended midazolam over other benzodiazepines. Thirty-two (94%) of 34 allowed for use of midazolam, with variable use of other AEDs. All allowed for use of intramuscular AED. Twenty-six (77%) allowed for intranasal AED. Nine (27%) allowed emergency medical services to administer a patient's own abortive AED, and 6 (18%) allowed for use of a patient's vagal nerve stimulator, when present. There was a wide variability with respect to dosing ranges for medications. Thirty-two (94%) of 34 included blood glucose measurement within the protocol. Twenty-one protocols (62%) provided recommendations for febrile seizures, including recommending active/passive cooling (8/34, 24%) and antipyretic administration (9/34, 26%).

CONCLUSIONS

All statewide protocols carried specific guidelines for the prehospital management of pediatric seizures; however, there was wide variability with respect to specific AEDs, routes of administration, and drug dosages. In addition to broader availability of statewide guidance, areas of potential protocol improvement and research include AED dose optimization, reprioritization of blood glucose, and greater emphasis on intranasal or intramuscular medication dosing.

Systemic Defenses to Prevent Intravenous Medication Errors in Hospitals: A Systematic Review

OBJECTIVES

Intravenous medication delivery is a complex process that poses systemic risks of errors. The objective of our study was to identify systemic defenses that can prevent in-hospital intravenous (IV) medication errors.

METHODS

A systematic review adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted. We searched MEDLINE (Ovid), Scopus, CINAHL, and EMB reviews for articles published between January 2005 and June 2016. Peer-reviewed journal articles published in English were included. Two reviewers independently selected articles according to a predetermined PICO tool. The quality of studies was assessed using the Grading of Recommendations Assessment, Development and Evaluation system, and the evidence was analyzed using qualitative content analysis.

RESULTS

Forty-six studies from 11 countries were included in the analysis. We identified systemic defenses related to administration (n = 24 studies), prescribing (n = 8), preparation (n = 6), treatment monitoring (n = 2), and dispensing (n = 1). In addition, 5 studies explored defenses related to multiple stages of the drug delivery process. Systemic defenses including features of closed-loop medication management systems appeared in 61% of the studies, with smart pumps being the defense most widely studied (24%). The evidence quality of the included articles was limited, as 83% were graded as low quality, 13% were of moderate quality, and only 4% were of high quality.

CONCLUSIONS

In-hospital IV medication processes are developing toward closed-loop medication management systems. Our study provides health care organizations with preliminary knowledge about systemic defenses that can prevent IV medication errors, but more rigorous evidence is needed. There is a need for further studies to explore combinations of different systemic defenses and their effectiveness in error prevention throughout the drug delivery process.

Interventions to Reduce Problems Related to the Readability and Comprehensibility of Drug Packages and Labels: A Systematic Review

OBJECTIVE

The aim of the study was to evaluate the effectiveness of interventions designed to reduce problems with readability and comprehensibility in drug labels.

METHODS

A systematic review of observational and experimental studies was conducted using MEDLINE (via PubMed), Embase, and Scopus databases. Two independent reviewers selected articles and collected data about study design, interventions, and outcomes.

RESULTS

Of 1786 studies screened, 17 were included in this systematic review. The main findings were described according to the type of intervention in the drug package or label: color-coded labels (7 studies); changes in information layout (5 studies); changes in font size (3 studies); and interventions involving look-alike/sound-alike (LASA) drugs (3 studies). Color changes were important both for healthcare professionals to improve safety in hospital practice and for medication users to differentiate between the types of insulin. Layout changes were effective and included highlighting key information, such as medication name, dose, and instructions. Increased font size yielded good results in the recognition and identification of medications mainly for the population with impaired vision. This review was limited by the heterogeneity of interventions and populations studied, as well as the small number of high-quality studies, which prevented meta-analysis across any one intervention or outcome.

CONCLUSIONS

All studies reported positive results for the proposed interventions. In the case of LASA drug names, the use of resources beyond Tall Man lettering (such as color and highlighting) reduced recognition errors, which may contribute to the development of new strategies to improve safety in the use of LASA drugs.

Impact of a Mobile App on Paramedics' Perceived and Physiologic Stress Response During Simulated Prehospital Pediatric Cardiopulmonary Resuscitation: Study Nested Within a Multicenter Randomized Controlled Trial

BACKGROUND

Out-of-hospital cardiac arrests (OHCAs) are stressful, high-stake events that are associated with low survival rates. Acute stress experienced in this situation is associated with lower cardiopulmonary resuscitation performance in calculating drug dosages by emergency medical services. Children are particularly vulnerable to such errors. To date, no app has been validated to specifically support emergency drug preparation by paramedics through reducing the stress level of this procedure and medication errors.

OBJECTIVE

This study aims to determine the effectiveness of an evidence-based mobile app compared with that of the conventional preparation methods in reducing acute stress in paramedics at the psychological and physiological levels while safely preparing emergency drugs during simulated pediatric OHCA scenarios.

METHODS

In a parent, multicenter, randomized controlled trial of 14 emergency medical services, perceived and physiologic stress of advanced paramedics with drug preparation autonomy was assessed during a 20-minute, standardized, fully video-recorded, and highly realistic pediatric OHCA scenario in an 18-month-old child. The primary outcome was participants' self-reported psychological stress perceived during sequential preparations of 4 intravenous emergency drugs (epinephrine, midazolam, 10% dextrose, and sodium bicarbonate) with the support of the PedAMINES (Pediatric Accurate Medication in Emergency Situations) app designed to help pediatric drug preparation (intervention) or conventional methods (control). The State-Trait Anxiety Inventory and Visual Analog Scale questionnaires were used to measure perceived stress. The secondary outcome was physiologic stress, measured by a single continuous measurement of the participants' heart rate with optical photoplethysmography.

RESULTS

From September 3, 2019, to January 21, 2020, 150 advanced paramedics underwent randomization. A total of 74 participants were assigned to the mobile app (intervention group), and 76 did not use the app (control group). A total of 600 drug doses were prepared. Higher State-Trait Anxiety Inventory-perceived stress increase from baseline was observed during the scenario using the conventional methods (mean 35.4, SD 8.2 to mean 49.8, SD 13.2; a 41.3%, 35.0 increase) than when using the app (mean 36.1, SD 8.1 to mean 39.0, SD 8.4; a 12.3%, 29.0 increase). This revealed a 30.1% (95% CI 20.5%-39.8%; P<.001) lower relative change in stress response in participants who used the app. On the Visual Analog Scale questionnaire, participants in the control group reported a higher increase in stress at the peak of the scenario (mean 7.1, SD 1.8 vs mean 6.4, SD 1.9; difference: -0.8, 95% CI -1.3 to -0.2; P=.005). Increase in heart rate during the scenario and over the 4 drugs was not different between the 2 groups.

CONCLUSIONS

Compared with the conventional method, dedicated mobile apps can reduce acute perceived stress during the preparation of emergency drugs in the prehospital setting during critical situations. These findings can help advance the development and evaluation of mobile apps for OHCA management and should be encouraged.

Investigation of interventions to reduce nurses' medication errors in adult intensive care units: A systematic review

BACKGROUND

Medication errors in adult intensive care units (ICUs) are both frequent and harmful. For nurses, these errors may be multifactorial and multidisciplinary, extending from prescription stage to monitoring of patient response to medication. Therefore, diverse interventions have been developed to optimise the medication process to prevent such errors.

OBJECTIVES

The objective of this systematic review was to identify research investigating interventions that may be effective in reducing the rate of nurses' medication errors in adult ICUs.

METHODS

A systematic search was undertaken of three databases: Cumulative Index of Nursing and Allied Health Literature, Medical Literature Analysis and Retrieval System Online, and EMCARE using a combination of key terms related to "medication errors", "nurses", "interventions", and "intensive care units". The search was limited to studies published in English between 2009 and 2019. Independent screening, quality appraisal, and data extraction were undertaken by two reviewers.

RESULTS

A total of 464 records were identified from database searches. Eleven studies met inclusion criteria: ten were quasi-experimental designs and one was a randomised controlled trial. Studies examined six types of interventions: prefilled syringes, barcode-assisted medication administration, an automated dispensing system, nursing education programs, a protocolised program logic form, and a preventive interventions program with protocols and pharmacist-supported supervision and monitoring. Findings revealed that a prefilled syringe, nurses' education programs, and the protocolised program logic form were most effective in reducing medication errors. For the barcode-assisted medication administration, automated dispensing systems, and a preventive interventions program with protocols and pharmacist-supported supervision and monitoring, results showed wide variability in effectiveness.

CONCLUSION

This review found that the evidence for effective interventions to reduce nurses' medication errors in adult ICUs is limited, due largely to inconsistencies in research design and methods. Therefore, further studies such as randomised controlled trials focusing on a single intervention are required to provide robust evidence of the effectiveness of interventions.

The Effect of Numbered Jerseys on Directed Commands, Teamwork, and Clinical Performance During Simulated Emergencies

ABSTRACT

Communication and teamwork are essential during inpatient emergencies such as cardiac arrest and rapid response (RR) codes. We investigated whether wearing numbered jerseys affect directed commands, teamwork, and performance during simulated codes. Eight teams of 6 residents participated in 64 simulations. Four teams were randomized to the experimental group wearing numbered jerseys, and four to the control group wearing work attire. The experimental group used more directed commands (49% vs. 31%, p < .001) and had higher teamwork score (25 vs. 18, p < .001) compared with control group. There was no difference in time to initiation of chest compression, bag-valve-mask ventilation, and correct medications. Time to defibrillation was longer in the experimental group (190 vs. 140 seconds, p = .035). Using numbered jerseys during simulations was associated with increased use of directed commands and better teamwork. Time to performance of clinical actions was similar except for longer time to defibrillation in the jersey group.

A study of medication errors during the prescription stage in the pediatric critical care services of a secondary-tertiary level public hospital

Background

Medication Errors (MEs) are considered the most common type of error in pediatric critical care services. Moreover, the ME rate in pediatric patients is up to three times higher than the rate for adults. Nevertheless, information in pediatric population is still limited, particularly in emergency/critical care practice. The purpose of this study was to describe and analyze MEs in the pediatric critical care services during the prescription stage in a Mexican secondary-tertiary level public hospital.

Methods

A cross-sectional study to detect MEs was performed in all pediatric critical care services [pediatric emergency care (PEC), pediatric intensive care unit (PICU), neonatal intensive care unit (NICU), and neonatal intermediate care unit (NIMCU)] of a public teaching hospital. A pharmacist identified MEs by direct observation as the error detection method and MEs were classified according to the updated classification for medication errors by the Ruíz-Jarabo 2000 working group. Thereafter, these were subclassified in clinically relevant MEs.

Results

In 2347 prescriptions from 301 patients from all critical care services, a total of 1252 potential MEs (72%) were identified, and of these 379 were considered as clinically relevant due to their potential harm. The area with the highest number of MEs was PICU (n = 867). The ME rate was > 50% in all pediatric critical care services and PICU had the highest ME/patient index (13.1). The most frequent MEs were use of abbreviations (50.9%) and wrong speed rate of administration (11.4%), and only 11.7% of the total drugs were considered as ideal medication orders.

Conclusion

Clinically relevant medication errors can range from mild skin reactions to severe conditions that place the patient’s life at risk. The role of pharmacists through the detection and timely intervention during the prescription and other stages of the medication use process can improve drug safety in pediatric critical care services.

A Cognitive Aid for Neonatal Epinephrine Dosing

OBJECTIVES

Errors are common when preparing epinephrine for neonatal resuscitation. Epinephrine is available in two concentrations (1 mg/mL and 1 mg/10 mL) and requires weight-based calculations, which increases the risk of dosing errors. We developed a printed cognitive aid to assist with dose preparation. We hypothesized that the cognitive aid would result in a 25% difference in errors in preparing the dose of epinephrine during simulated neonatal resuscitation.

METHODS

Nurses (N = 100) in a large academic and community hospital were randomly assigned to calculate the intended dose and prepare epinephrine for neonatal resuscitation with or without the cognitive aid. Scenarios were video recorded and timed. Secondary outcomes included errors in the written intended dose, errors in choosing the correct epinephrine concentration, and time required to prepare the final dose. Proportions were compared by using Fisher's exact test. Variables influencing dosing errors were investigated by using logistic regression.

RESULTS

Using the cognitive aid significantly decreased the proportion of doses prepared incorrectly (24% vs 50%; P = .01). The aid also decreased errors in choosing the correct epinephrine concentration (12% vs 44%; P < .001), but there was no difference in the written intended dose or the time to prepare the dose. Years of experience, self-perceived math comfort, and anxiety were not predictive of dosing errors.

CONCLUSIONS

A simple cognitive aid decreased epinephrine dosing errors during simulated neonatal resuscitation but did not improve efficiency. Despite the effectiveness of the cognitive aid, errors were not completely eliminated. This is a serious safety risk for newborns and requires additional interventions.

Drug dosing errors in simulated paediatric emergencies - Comprehensive dosing guides outperform length-based tapes with precalculated drug doses

BACKGROUND

The accuracy of drug dosing calculations during medical emergencies in children has not been evaluated extensively. The objectives of this study were to evaluate the accuracy of drug dose calculations using the Broselow tape, the PAWPER XL tape plus its companion drug-dosing guide, a custom-designed mobile phone app and no drug-dosing aid (control group).

METHODS

This was a prospective study in which 32 emergency medicine volunteers participated in eight simulations of common paediatric emergency conditions, using children models. The participants used the three methods to estimate the children's weight and calculate drug doses. The accuracy of and time taken for the drug dose determinations were then evaluated for each of the methods.

RESULTS

The overall accuracy of drug dose determinations was extremely and potentially dangerously low in the control group in which no dosing guide was used as well as in the Broselow tape group (<20% of doses were correct). The accuracy was significantly higher with the PAWPER XL tape group and the mobile app group (47% and 31% respectively). The times taken to obtain the required information did not differ in a clinically meaningful magnitude.

CONCLUSIONS

Both an accurate weight estimation and a dosing guide with comprehensive information were necessary to produce an accurate prescription. The information on the Broselow tape was not sufficient for this purpose. The current guidelines recommending the use of tapes with limited information should be revised. The results from the comprehensive dosing guides were substantially better, but still had a lower proportion of accurate prescriptions than desirable. The role of training in every aspect of the emergency paediatric weight estimation and drug dosing procedure cannot be underestimated and should be routine in any environment where emergency care may be needed.

Intubation drug pack containing pre-filled syringes reduces the time to endotracheal intubation in a simulated paediatric emergency

To determine if an intubation drugs pack containing pre-filled syringes can reduce the time to endotracheal intubation compared with standard care during a simulated paediatric emergency. Twenty doctors (10 consultants and 10 registrars) who worked in the paediatric intensive care unit or anaesthetic department of a tertiary paediatric hospital were asked to participate in an in situ simulated emergency paediatric intubation scenario. The participants were instructed to prepare and administer intubation medications. They were randomised to either an intubation drug pack, containing pre-filled syringes or to standard care where each of the drugs had to be individually drawn-up. The mean time to intubation when using the pre-filled syringes of 159.5 s was over three times faster than with standard care of 497.5 s (p<0.001), allowing intubation to occur on average 5 min and 38 s earlier. Utilising an intubation drug pack containing pre-filled syringes significantly reduced the time from decision to intubate to intubation in a simulated paediatric emergency. This applied irrespective of clinical experience with registrars utilising the pre-filled syringes outperforming consultant anaesthetists when they used standard care.

Medication errors during simulated paediatric resuscitations: a prospective, observational human reliability analysis

INTRODUCTION

Medication errors during paediatric resuscitation are thought to be common. However, there is little evidence about the individual process steps that contribute to such medication errors in this context.

OBJECTIVES

To describe the incidence, nature and severity of medication errors in simulated paediatric resuscitations, and to employ human reliability analysis to understand the contribution of discrepancies in individual process steps to the occurrence of these errors.

METHODS

We conducted a prospective observational study of simulated resuscitations subjected to video microanalysis, identification of medication errors, severity assessment and human reliability analysis in a large English teaching hospital. Fifteen resuscitation teams of two doctors and two nurses each conducted one of two simulated paediatric resuscitation scenarios.

RESULTS

At least one medication error was observed in every simulated case, and a large magnitude (>25% discrepant) or clinically significant error in 11 of 15 cases. Medication errors were observed in 29% of 180 simulated medication administrations, 40% of which considered to be moderate or severe. These errors were the result of 884 observed discrepancies at a number of steps in the drug ordering, preparation and administration stages of medication use, 8% of which made a major contribution to a resultant medication error. Most errors were introduced by discrepancies during drug preparation and administration.

CONCLUSIONS

Medication errors were common with a considerable proportion likely to result in patient harm. There is an urgent need to optimise existing systems and to commission research into new approaches to increase the reliability of human interactions during administration of medication in the paediatric emergency setting.

A mobile device app to reduce prehospital medication errors and time to drug preparation and delivery by emergency medical services during simulated pediatric cardiopulmonary resuscitation: study protocol of a multicenter, prospective, randomized controlled trial

BACKGROUND

Emergency drug preparation and administration in children is both complex and time-consuming and places this population at a higher risk than adults for medication errors. Moreover, survival and a favorable neurological outcome from cardiopulmonary resuscitation are inversely correlated to drug preparation time. We developed a mobile device application (the pediatric Accurate Medication IN Emergency Situations (PedAMINES) app) as a step-by-step guide for the preparation to delivery of drugs requiring intravenous injection. In a previous multicenter randomized trial, we reported the ability of this app to significantly reduce in-hospital continuous infusion medication error rates and drug preparation time compared to conventional preparation methods during simulation-based pediatric resuscitations. This trial aims to evaluate the effectiveness of this app during pediatric out-of-hospital cardiopulmonary resuscitation.

METHODS/DESIGN

We will conduct a multicenter, prospective, randomized controlled trial to compare the PedAMINES app with conventional calculation methods for the preparation of direct intravenously administered emergency medications during standardized, simulation-based, pediatric out-of-hospital cardiac arrest scenarios using a high-fidelity manikin. One hundred and twenty paramedics will be randomized (1:1) in several emergency medical services located in different regions of Switzerland. Each paramedic will be asked to prepare, sequentially, four intravenously administered emergency medications using either the app or conventional methods. The primary endpoint is the medication error rates. Enrollment will start in mid-2019 and data analysis in late 2019. We anticipate that the intervention will be completed in early 2020 and study results will be submitted in late 2020 for publication (expected in early 2021).

DISCUSSION

This clinical trial will assess the impact of an evidence-based mobile device app to reduce the rate of medication errors, time to drug preparation and time to drug delivery during prehospital pediatric resuscitation. As research in this area is scarce, the results generated from this study will be of great importance and may be sufficient to change and improve prehospital pediatric emergency care practice.

Volume Versus Mass Dosing of Epinephrine for Neonatal Resuscitation: A Randomized Trial

BACKGROUND

Intravenous epinephrine for neonatal resuscitation requires weight-based calculations. Epinephrine is available in 2 different concentrations, increasing the risk of dosing errors. Expert panels have conflicting recommendations for the ordering method. The Neonatal Resuscitation Program recommends the volume (milliliters per kilogram) method, whereas the Institute for Safe Medication Practices recommends the mass (milligrams per kilogram) method. In this study, we aim to determine if the mass method is more accurate and efficient than the volume method.

METHODS

In a randomized crossover simulation study, 70 NICU and pediatric emergency department nurses calculated the intended dose then prepared epinephrine using both the mass and volume methods. Both epinephrine concentrations were available. Scenarios were video recorded and timed. The primary outcome was the proportion of epinephrine doses prepared correctly. Variables associated with correct dosing were analyzed by using logistic regression.

RESULTS

Of 136 total doses, 77 (57%) were prepared correctly. The correct intended dose was calculated more frequently by using the mass method (82% vs 68%; risk difference 15%; 95% confidence interval 3% to 26%), but there was no difference in the proportion of doses that were actually prepared correctly (53% of mass method doses versus 60% of volume method doses; risk difference -7%; 95% confidence interval -24% to 9%). There was no difference between methods in the time required to prepare the dose. Selecting the correct epinephrine concentration was the only variable associated with correct dosing.

CONCLUSIONS

The mass method was neither more accurate nor more efficient. Nurses made frequent errors when using both methods. This is a serious patient safety risk. Additional educational and medication safety interventions are urgently needed.

Drug preparation and administration errors during simulated paediatric resuscitations

INTRODUCTION

Very few studies have assessed drug preparation and administration errors during paediatric resuscitation. Current evidence suggests that medication errors in paediatrics are a serious problem. The aim of this study was to evaluate drug preparation and administration errors incurred during the simulated resuscitation of paediatric patients.

METHODS

This was a prospective observational study performed in the emergency department of a tertiary-level hospital. Teams consisting of two emergency doctors were tasked with preparing and delivering medication during simulated emergency scenarios. Preparation processes were video recorded. All phials, syringes and administered volumes were collected and analysed to determine the accuracy of drug preparation and delivery. Deviations from intended volumes were calculated.

MAIN RESULTS

A total of 96 dosages were recorded from 24 participants. Most errors were identified in the withdrawal of drug phase (prior to dilution) (13 of 96 doses had a >20% error), and the administration of medication phase (20 of 96 doses had a >20% error). Overall the median time taken to deliver each drug was 79 s (IQR 59, 100 s). The largest percentage errors were seen when a large syringe was used to withdraw or administer a small volume of medication.

CONCLUSION

The study clearly demonstrated that there were significant errors in the preparation and administration of medication. Training in the preparation and administration of paediatric medications should be available for all emergency nurses and doctors. Correct syringe choice may reduce these errors-smaller syringes should be used for withdrawing or administering smaller volumes.

Efficacy of low-dose nebulized epinephrine as treatment for croup: A randomized, placebo-controlled, double-blind trial

OBJECTIVE

Croup treatment usually involves a single dose of systemic dexamethasone combined with nebulized epinephrine. However, the optimal dose of l-epinephrine remains unclear. We examined whether a low dose (0.1 mg/kg) was inferior to the conventional dose (0.5 mg/kg) of 1:1000 nebulized l-epinephrine in patients with moderate to severe croup.

METHODS

This randomized double-blind clinical non-inferiority trial was conducted in three pediatric emergency departments from May 2015 to October 2017. Children 6 months to 5 years old with moderate to severe croup (Westley scale scores 3-11) were eligible. Subjects were randomly assigned to the conventional dose (0.5 mg/kg: maximum 5 mg) or low dose (0.1 mg/kg; maximum 1 mg) group. All subjects received 0.6 mg/kg dexamethasone. Croup scores and other vital signs were measured before and at 30, 60, 90, and 120 min after nebulized l-epinephrine administration. The primary outcome was the change in croup score after 30 min.

RESULTS

The final analysis included 84 patients. The groups did not differ significantly in terms of demographic parameters. At 30 min after treatment with nebulized l-epinephrine, the croup scores in both groups were significantly reduced from the baseline values (p < 0.05) and did not differ between the two groups (p = 0.42). Neither blood pressure nor heart rate differed between the two groups.

CONCLUSIONS

Low-dose 1:1000 l-epinephrine was not inferior in croup score reduction to the conventional dose in patients with moderate to severe croup. Clinical trial No: NCT01664507, KCT0002318.

A systematic review of epinephrine stability and sterility with storage in a syringe

Background

Epinephrine is a lifesaving medication in the treatment of anaphylaxis. Epinephrine auto-injectors are the preferred method of epinephrine administration, but are not universally available or affordable. Little is known about the effects on epinephrine when it is drawn up in advance and stored as prefilled syringes.

Objective

To study the stability and sterility of epinephrine when stored in syringes.

Methods

We searched Embase, Medline, and Web of Science in June 2016 for all studies of epinephrine stored in syringes in concentrations between 0.1 and 1 mg/mL that measured epinephrine stability and/or sterility over time, regardless of date published or language.

Results

Three studies were included, one testing two concentrations of epinephrine. Only one study tested epinephrine 1 mg/mL, the concentration clinically relevant for intramuscular use during anaphylaxis. Neither this study nor the one study testing 0.7 mg/mL epinephrine found significant degradation after 56 and 90 days, respectively. One of the two studies testing epinephrine at a concentration of 0.1 mg/mL found significant degradation by 14 days; the other found no degradation up to 168 days. Two studies tested for bacterial growth, with none detected after 28 and 90 days, respectively. One study tested for fungal growth, with none detected after 90 days.

Conclusions

Limited evidence suggests that syringes filled with 1 mg/mL epinephrine are stable and sterile for 90 days. More research is needed testing the duration of stability and sterility of prefilled syringes with the 1 mg/mL concentration most commonly used in anaphylaxis, testing more extensively in different storage conditions and across a wider range of marketed syringe brands.

Comparing the usability of paediatric weight estimation methods: a simulation study

OBJECTIVE

Estimating weight is essential in order to prepare appropriate sized equipment and doses of resuscitation drugs in cases where children are critically ill or injured. Many methods exist with varying degrees of complexity and accuracy. The most recent version of the Advanced Paediatric Life Support (APLS) course has changed their teaching from an age-based calculation method to the use of a reference table. We aimed to evaluate the potential implications of this change.

METHOD

Using a bespoke online simulation platform we assessed the ability of acute paediatric staff to apply different methods of weight estimation. Comparing the time taken, rate and magnitude of errors were made using the APLS single and triple age-based formulae, Best Guess and reference table methods. To add urgency and an element of cognitive stress, a time-based competitive component was included.

RESULTS

57 participants performed a total of 2240 estimates of weight. The reference table was the fastest (25 (22-28) vs 35 (31-38) to 48 (43-51) s) and most preferred, but errors were made using all methods. There was no significant difference in the percentage accuracy between methods (93%-97%) but the magnitude of errors made was significantly smaller using the three APLS formulae 10% (6.5-21) compared with reference table (69% (34-133)) mainly from month/year table confusion.

CONCLUSION

In this exploratory study under psychological stress none of the methods of weight estimation were free from error. Reference tables were the fastest method and also had the largest errors and should be designed to minimise the risk of picking errors.

Videographic Assessment of the Quality of EMS to ED Handoff Communication During Pediatric Resuscitations

BACKGROUND

The National Association of Emergency Medical Services (EMS) Physicians emphasizes the importance of high quality communication between EMS providers and emergency department (ED) staff for providing safe, effective care. The Joint Commission has identified ineffective handoff communication as a contributing factor in 80% of serious medical errors. The quality of handoff communication from EMS to ED teams for critically ill pediatric patients needs further exploration.

OBJECTIVE

This study assessed the quality of handoff communication between EMS and ED staff during pediatric medical resuscitations.

METHODS/DESIGN

We conducted a retrospective review of video recordings of pediatric patients who required critical care ("resuscitation") in the ED between January 2014 and February 2016 at a Level 1 pediatric trauma center. Handoff quality between EMS and emergency department teams was assessed for completeness, timeliness, and efficiency. Institutional review board approval was obtained.

RESULTS

Sixty-eight resuscitations were reviewed; 28% presented in cardiac arrest, requiring cardiopulmonary resuscitation (CPR). Completeness of information communicated was variable and included chief complaint (88%), prehospital interventions (81%), physical exam findings (63%), medical history (59%), age (56%), and weight (20%). Completeness of specific vital sign reporting included: respiratory rate (53%), heart rate (43%), oxygen saturation (39%), and blood pressure (31%). Timeliness of communication included median patient handoff and report times of 50 seconds [IQR 30,74] and 108 seconds [IQR 62,252], respectively. Inefficient communication occurred in 87% of handoffs, including interruptions by ED staff (51%), questions from the ED physician team leader asking for information already communicated (40%), and questions by ED physician team leader requesting information not yet communicated (65%). When comparing non-CPR to CPR cases, only timeliness of patient handoff was significantly different for those patients receiving prehospital CPR.

CONCLUSION

Handoff communication between EMS and ED teams during pediatric resuscitation was frequently incomplete and inefficient. Future educational and quality improvement interventions could aim to improve the quality of handoff communication for this patient population.

Randomized controlled trials of simulation-based interventions in Emergency Medicine: a methodological review

The number of trials assessing Simulation-Based Medical Education (SBME) interventions has rapidly expanded. Many studies show that potential flaws in design, conduct and reporting of randomized controlled trials (RCTs) can bias their results. We conducted a methodological review of RCTs assessing a SBME in Emergency Medicine (EM) and examined their methodological characteristics. We searched MEDLINE via PubMed for RCT that assessed a simulation intervention in EM, published in 6 general and internal medicine and in the top 10 EM journals. The Cochrane Collaboration risk of Bias tool was used to assess risk of bias, intervention reporting was evaluated based on the "template for intervention description and replication" checklist, and methodological quality was evaluated by the Medical Education Research Study Quality Instrument. Reports selection and data extraction was done by 2 independents researchers. From 1394 RCTs screened, 68 trials assessed a SBME intervention. They represent one quarter of our sample. Cardiopulmonary resuscitation (CPR) is the most frequent topic (81%). Random sequence generation and allocation concealment were performed correctly in 66 and 49% of trials. Blinding of participants and assessors was performed correctly in 19 and 68%. Risk of attrition bias was low in three-quarters of the studies (n = 51). Risk of selective reporting bias was unclear in nearly all studies. The mean MERQSI score was of 13.4/18.4% of the reports provided a description allowing the intervention replication. Trials assessing simulation represent one quarter of RCTs in EM. Their quality remains unclear, and reproducing the interventions appears challenging due to reporting issues.

Accuracy of weight estimation by the Broselow tape is substantially improved by including a visual assessment of body habitus

BackgroundThe Broselow tape (BT) has been shown to estimate weight poorly primarily because of variations in body habitus. The manufacturers have suggested that a visual assessment of habitus may be used to increase its performance. This study evaluated the ability of habitus-modified models to improve the accuracy thereof.MethodsA post hoc analysis of prospectively collected data from four hospitals in Johannesburg, South Africa, on a population of 1,085 children. Sixteen a priori models generated a modified weight estimation or drug dose based on the BT weight and a gestalt assessment of habitus.ResultsThe habitus-modified method suggested by the manufacturer did not improve the accuracy of the BT. Five dosing and four weight-estimation models were identified that markedly improved dosing and weight estimation accuracy, respectively. The best dosing model improved dosing accuracy (doses within 10% of correct dose) from 52.0 to 69.6% and reduced critical dosing errors from 16.5 to 4.3%. The best weight-estimation model improved accuracy from 59.4 to 81.9% and reduced critical errors from 11.8 to 1.9%.ConclusionThe accuracy of the BT as a drug-dosing and weight-estimation device can be substantially improved by including an appraisal of body habitus in the methodology.

The accuracy of the Broselow tape as a weight estimation tool and a drug-dosing guide - A systematic review and meta-analysis

AIMS

The Broselow tape is widely used as a weight-estimation device and drug-dosing guide aid, but concerns about its accuracy and its efficacy have emerged in the last decade. The aim of this study was to systematically review the literature to analyse the accuracy of the Broselow tape as a weight estimation device and review evidence of its utility as a drug-dosing guide.

METHODS

This was a MOOSE-driven systematic review and meta-analysis, which focused on studies evaluating the accuracy of the Broselow tape and studies reviewing its use as a drug-dosing aid.

MAIN RESULTS

The tape has undergone substantial changes over the years, but there was no evidence to show that the changes have improved weight-estimation performance. The weight-estimation accuracy of the tape was suboptimal in all populations, with just over 50% of children receiving an estimation within 10% of their actual weight. The overestimation of weight in low- and middle-income countries was often extreme. This indicated a significant potential for potentially harmful medication errors. The limited available evidence on the value of the tape as a drug-dosing guide indicated that the tape was frequently used incorrectly and contained insufficient information to function without additional resources.

CONCLUSIONS

The Broselow tape lacked sufficient accuracy as a weight estimation and drug-dosing tool when compared to other available techniques. In addition, the Broselow tape contains insufficient drug-dosing information to function as a complete resuscitation aid without additional material. The frequent rate of incorrect usage of the tape indicated that appropriate training with the tape is mandatory to reduce errors.

A Mobile Device App to Reduce Medication Errors and Time to Drug Delivery During Pediatric Cardiopulmonary Resuscitation: Study Protocol of a Multicenter Randomized Controlled Crossover Trial

BACKGROUND

During pediatric cardiopulmonary resuscitation (CPR), vasoactive drug preparation for continuous infusions is complex and time-consuming. The need for individual specific weight-based drug dose calculation and preparation places children at higher risk than adults for medication errors. Following an evidence-based and ergonomic driven approach, we developed a mobile device app called Pediatric Accurate Medication in Emergency Situations (PedAMINES), intended to guide caregivers step-by-step from preparation to delivery of drugs requiring continuous infusion. In a prior single center randomized controlled trial, medication errors were reduced from 70% to 0% by using PedAMINES when compared with conventional preparation methods.

OBJECTIVE

The purpose of this study is to determine whether the use of PedAMINES in both university and smaller hospitals reduces medication dosage errors (primary outcome), time to drug preparation (TDP), and time to drug delivery (TDD) (secondary outcomes) during pediatric CPR when compared with conventional preparation methods.

METHODS

This is a multicenter, prospective, randomized controlled crossover trial with 2 parallel groups comparing PedAMINES with a conventional and internationally used drug infusion rate table in the preparation of continuous drug infusion. The evaluation setting uses a simulation-based pediatric CPR cardiac arrest scenario with a high-fidelity manikin. The study involving 120 certified nurses (sample size) will take place in the resuscitation rooms of 3 tertiary pediatric emergency departments and 3 smaller hospitals. After epinephrine-induced return of spontaneous circulation, nurses will be asked to prepare a continuous infusion of dopamine using either PedAMINES (intervention group) or the infusion table (control group) and then prepare a continuous infusion of norepinephrine by crossing the procedure. The primary outcome is the medication dosage error rate. The secondary outcome is the time in seconds elapsed since the oral prescription by the physician to drug delivery by the nurse in each allocation group. TDD includes TDP. Stress level during the resuscitation scenario will be assessed for each participant by questionnaire and recorded by the heart rate monitor of a fitness watch. The study is formatted according to the Consolidated Standards of Reporting Trials Statement for Randomized Controlled Trials of Electronic and Mobile Health Applications and Online TeleHealth (CONSORT-EHEALTH) and the Reporting Guidelines for Health Care Simulation Research.

RESULTS

Enrollment and data analysis started in March 2017. We anticipate the intervention will be completed in late 2017, and study results will be submitted in early 2018 for publication expected in mid-2018. Results will be reported in line with recommendations from CONSORT-EHEALTH and the Reporting Guidelines for Health Care Simulation Research .

CONCLUSIONS

This paper describes the protocol used for a clinical trial assessing the impact of a mobile device app to reduce the rate of medication errors, time to drug preparation, and time to drug delivery during pediatric resuscitation. As research in this area is scarce, results generated from this study will be of great importance and might be sufficient to change and improve the pediatric emergency care practice.

Time delays associated with vasoactive medication preparation and delivery in simulated patients at risk of cardiac arrest

PURPOSE

To compare, quantify, and describe the time-delays associated with four common methods of adrenaline administration in the simulated setting of impending cardiac arrest.

METHODS

Using sham medication and a high-fidelity simulator, experienced Nurses prepared, then delivered, adrenaline by: i) bolus, ii) lower-concentration infusion iii) higher-concentration infusion, and iv) higher-concentration infusion plus carrier-line. We recorded medication preparation and delivery time, plus administration errors and self-reported competence.

RESULTS

Median total delay was i) 120s for bolus (95% CI 112-128s); ii) 179s for lower concentration infusion (95% CI 172-186s); iii) 296s for higher concentration infusion (95% CI 285-307s); and iv) 411s for higher concentration infusion plus carrier line (95% CI 399-423s). Time to prepare/deliver a bolus was less than any infusion (p<0.001). Time to prepare/deliver a lower-concentration infusion was less than either higher-concentration infusion (p<0.001). No substantial equipment failures or medication errors were observed. Participants reported high-competence. The majority of delay was from drug preparation not delivery.

CONCLUSIONS

We highlight potentially dangerous delays with administration of life-saving medications by all four methods. We should prioritize boluses, and focus on improving drug preparation times and human performance, more than drug delivery and equipment.

Decreasing Prescribing Errors During Pediatric Emergencies: A Randomized Simulation Trial

OBJECTIVE

To evaluate whether a clinical aid providing precalculated medication doses decreases prescribing errors among residents during pediatric simulated cardiopulmonary arrest and anaphylaxis.

METHODS

A crossover randomized trial was conducted in a tertiary care hospital simulation center with residents rotating in the pediatric emergency department. The intervention was a reference book providing weight-based precalculated doses. The control group used a card providing milligram-per-kilogram doses. The primary outcome was the presence of a prescribing error, defined as a dose varying by ≥20% from the recommended dose or by incorrect route. Residents were involved in 2 sets of paired scenarios and were their own control group. Primary analysis was the difference in mean prescribing error proportions between both groups.

RESULTS

Forty residents prescribed 1507 medications or defibrillations during 160 scenarios. The numbers of prescribing errors per 100 bolus medications or defibrillations were 5.1 (39 out of 762) and 7.5 (56 out of 745) for the intervention and control, respectively, a difference of 2.4 (95% confidence interval [CI], -0.1 to 5.0). However, the intervention was highly associated with lower risk of 10-fold error for bolus medications (odds ratio 0.27; 95% CI, 0.10 to 0.70). For medications administered by infusion, prescribing errors occurred in 3 out of 76 (4%) scenarios in the intervention group and 13 out of 76 (22.4%) in the control group, a difference of 13% (95% CI, 3 to 23).

CONCLUSIONS

A clinical aid providing precalculated medication doses was not associated with a decrease in overall prescribing error rates but was highly associated with a lower risk of 10-fold error for bolus medications and for medications administered by continuous infusion.

A Mobile Device App to Reduce Time to Drug Delivery and Medication Errors During Simulated Pediatric Cardiopulmonary Resuscitation: A Randomized Controlled Trial

Background

During pediatric cardiopulmonary resuscitation (CPR), vasoactive drug preparation for continuous infusion is both complex and time-consuming, placing children at higher risk than adults for medication errors. Following an evidence-based ergonomic-driven approach, we developed a mobile device app called Pediatric Accurate Medication in Emergency Situations (PedAMINES), intended to guide caregivers step-by-step from preparation to delivery of drugs requiring continuous infusion.

Objective

The aim of our study was to determine whether the use of PedAMINES reduces drug preparation time (TDP) and time to delivery (TDD; primary outcome), as well as medication errors (secondary outcomes) when compared with conventional preparation methods.

Methods

The study was a randomized controlled crossover trial with 2 parallel groups comparing PedAMINES with a conventional and internationally used drugs infusion rate table in the preparation of continuous drug infusion. We used a simulation-based pediatric CPR cardiac arrest scenario with a high-fidelity manikin in the shock room of a tertiary care pediatric emergency department. After epinephrine-induced return of spontaneous circulation, pediatric emergency nurses were first asked to prepare a continuous infusion of dopamine, using either PedAMINES (intervention group) or the infusion table (control group), and second, a continuous infusion of norepinephrine by crossing the procedure. The primary outcome was the elapsed time in seconds, in each allocation group, from the oral prescription by the physician to TDD by the nurse. TDD included TDP. The secondary outcome was the medication dosage error rate during the sequence from drug preparation to drug injection.

Results

A total of 20 nurses were randomized into 2 groups. During the first study period, mean TDP while using PedAMINES and conventional preparation methods was 128.1 s (95% CI 102-154) and 308.1 s (95% CI 216-400), respectively (180 s reduction, P=.002). Mean TDD was 214 s (95% CI 171-256) and 391 s (95% CI 298-483), respectively (177.3 s reduction, P=.002). Medication errors were reduced from 70% to 0% (P<.001) by using PedAMINES when compared with conventional methods.

Conclusions

In this simulation-based study, PedAMINES dramatically reduced TDP, to delivery and the rate of medication errors.

An assessment of the accuracy of a novel weight estimation device for children

BACKGROUND

We sought to validate the accuracy and assess the efficacy of a newly developed electronic weight estimation device (ie, the rolling tape) for paediatric weight estimation.

METHODS

We enrolled a convenience sample of children aged <17 years presenting to our emergency department who volunteered to participate in the study. The children's heights and weights were measured, and three researchers estimated these values using the rolling tape and Broselow tape at 5 min intervals. The weight estimates of researcher 1, researcher 2 and the Broselow tape were compared with measured values, and mean percentage error (MPE), root mean square error (RMSE) and percentage of estimates within 10% of the actual measured values were calculated. For 30 randomly selected subjects, we compared the time interval from the start of the measurement to the time that orders for epinephrine, defibrillation dose and instrument size could be given in a simulated arrest scenario.

RESULTS

We enrolled 906 children (median age 4.0 years). For researcher 1, researcher 2 and the Broselow tape, MPE values were 0.11% (RMSE 2.61 kg), 1.41% (RMSE, 2.61 kg) and 1.72% (RMSE 5.41 kg), respectively, and the percentages of children with predictions within 10% of their actual weight were 75.1%, 75.7% and 60.6%, respectively. In the 30 simulated cases, the mean time for measurement to ordering was significantly shorter (25.8 s vs 35.5 s, p<0.001) for the rolling tape compared with the Broselow tape method.

CONCLUSIONS

The rolling tape is a good weight estimation tool for children compared with other methods. The rolling tape method significantly decreased the time from weight estimation to orders for essential drug dose, instrument size and defibrillation dose for resuscitation.
