Higher resuscitation guideline adherence in paramedics with use of real-time ventilation feedback during simulated out-of-hospital cardiac arrest: A randomised controlled trial.

ABSTRACT:

Objectives

To investigate whether real-time ventilation feedback would improve provider adherence to ventilation guidelines.

Design

Non-blinded randomised controlled simulation trial.

Setting

One Emergency Medical Service trust in Copenhagen.

Participants

32 ambulance crews consisting of 64 on-duty basic or advanced life support paramedics from Copenhagen Emergency Medical Service.

Intervention

Participant exposure to real-time ventilation feedback during simulated out-of-hospital cardiac arrest.

Main outcome measures

The primary outcome was ventilation quality, defined as ventilation guideline-adherence to ventilation rate (8-10 bpm) and tidal volume (500-600 ml) delivered simultaneously.

Results

The intervention group performed ventilations in adherence with ventilation guideline recommendations for 75.3% (Interquartile range (IQR) 66.2%-82.9%) of delivered ventilations, compared to 22.1% (IQR 0%-44.0%) provided by the control group. When controlling for participant covariates, adherence to ventilation guidelines was 44.7% higher in participants receiving ventilation feedback. Analysed separately, the intervention group performed a ventilation guideline-compliant rate in 97.4% (IQR 97.1%-100%) of delivered ventilations, versus 66.7% (IQR 40.9%-77.9%) for the control group. For tidal volume compliance, the intervention group reached 77.5% (IQR 64.9%-83.8%) of ventilations within target compared to 53.4% (IQR 8.4%-66.7%) delivered by the control group.

Conclusions

Real-time ventilation feedback increased guideline compliance for both ventilation rate and tidal volume (combined and as individual parameters) in a simulated OHCA setting. Real-time feedback has the potential to improve manual ventilation quality and may allow providers to avoid harmful hyperventilation.

Project description:ImportanceMortality from pediatric out-of-hospital cardiac arrest (OHCA) is high and has not improved in decades, unlike adult mortality. The low frequency of pediatric OHCA and weight-based medication and equipment needs may lead to lower quality of pediatric resuscitation compared with adults.ObjectiveTo compare the quality of pediatric and adult resuscitation from OHCA in a controlled simulation environment and to evaluate whether teamwork, knowledge, experience, and cognitive load are associated with resuscitation performance.Design, setting, and participantsThis cross-sectional in-situ simulation study was conducted between September 2020 and August 2021 in the metropolitan area of Portland, Oregon, and included engine companies from fire-based emergency services (EMS) agencies.ExposuresParticipating EMS crews completed 4 simulation scenarios presented in random order: (1) adult female with ventricular fibrillation; (2) adult female with pulseless electrical activity; (3) school-aged child with ventricular fibrillation; and (4) infant with pulseless electrical activity. All patients were pulseless on EMS arrival. Data were captured by the research team in real time during the scenarios.Main outcomes and measuresThe primary outcome was defect-free care, which included correct cardiopulmonary resuscitation depth, rate, and compression to ventilation ratio, time to bag-mask ventilation, and time to defibrillation, if applicable. Outcomes were determined by direct observation by an experienced physician. Secondary outcomes included additional time-based interventions and the use of correct medication doses and equipment size. We measured teamwork using the clinical teamwork scale, cognitive load with the National Aeronautics and Space Administration task load index (NASA-TLX), and knowledge using advanced life support resuscitation tests.ResultsAmong the 215 clinicians (39 crews) who participated in 156 simulations, 200 (93%) were male, and the mean (SD) age was 38.7 (0.6) years. No pediatric shockable scenario was defect free and only 5 pediatric nonshockable scenarios (12.8%) were defect free, while 11 (28.2%) adult shockable scenarios and 27 adult nonshockable scenarios (69.2%) were defect free. The mental demand subscale of the NASA-TLX was higher in the pediatric compared with the adult scenarios (mean [SD] pediatric score, 59.1 [20.7]; mean [SD] adult score, 51.4 [21.1]; P = .01). Teamwork scores were not associated with defect-free care.Conclusions and relevanceIn this simulation study of OHCA, resuscitation quality was significantly lower for pediatric than adult resuscitation. Mental demand may have been a contributor.

Project description:Background Hospitals participating in the national Get With The Guidelines-Resuscitation registry receive an award for high rates of adherence to quality metrics for in-hospital cardiac arrest. We sought to evaluate whether awards based on these quality metrics can be considered a proxy for performance on cardiac arrest survival. Methods and Results Among 195 hospitals with continuous participation in Get With The Guidelines-Resuscitation between 2012 and 2015, we identified 78 that received an award (Gold or Silver) for ≥85% compliance for all 4 metrics for in-hospital cardiac arrest-time to chest compressions, ≤1 minute; time to defibrillation, ≤2 minutes; device confirmation of endotracheal tube placement; and a monitored/witnessed arrest-for at least 12 consecutive months during 2014 to 2015. Award hospitals had higher cardiac arrest volumes than nonaward hospitals but otherwise had similar site characteristics. During 2014 to 2015, award hospitals had higher rates of return of spontaneous circulation for in-hospital cardiac arrest than nonaward hospitals (median [interquartile range], 71% [64%-77%] versus 66% [59%-74%]; Spearman ρ, 0.19; P=0.009). However, rates of risk-standardized survival to discharge at award hospitals (median, 25% [interquartile range, 22%-30%]) were similar to nonaward hospitals (median, 24% [interquartile range, 12%-27%]; Spearman ρ, 0.13; P=0.06). Among hospitals in the best tertile for survival to discharge in 2014 to 2015, 55.4% (36/65) did not receive an award, with poor discrimination of high-performing hospitals by award status (C statistic, 0.53). Similarly, there was only a weak association between hospitals' award status in 2014 to 2015 and their rates of survival to discharge in the preceding 2-year period (Spearman ρ, 0.16; P=0.03). Conclusions The current recognition mechanism within a national registry for in-hospital cardiac arrest captures hospital performance on return of spontaneous circulation but is not well correlated with survival to discharge. This suggests that current awards for resuscitation quality may not adequately capture hospital performance on overall survival-the outcome of greatest interest to patients.

Project description:BackgroundIn out-of-hospital cardiac arrest (OHCA), decisions to terminate resuscitation or transport the patient to hospital are ethically fraught. However, little is known about paramedics' ethical concerns in these decision-making processes.ObjectiveTo develop an understanding of how paramedics experience ethical concerns in OHCA decision-making processes, and how this relates to the ethical concerns of patients' relatives.DesignA qualitative study using semi-structured interviews with paramedics and relatives of OHCA non-survivors.SettingTwo ambulance trusts in England.ParticipantsThirty-one paramedics, identified as decision-makers in adult OHCA events in which cardiopulmonary resuscitation (CPR) had been initiated, were interviewed. Fourteen interviews with relatives of OHCA non-survivors were also conducted.AnalysisThe interviews were analysed thematically, using a coding framework and following an empirical ethics approach.ResultsFour themes were developed: preventing harm to patients, best interests, caring for the patient's family and moral distress. Paramedics conceptualised preventing harm both as saving lives and as preventing an undignified death or a life with severe brain damage. Paramedics' and relatives' views of best interests were influenced by values such as patient dignity and assumptions about age and quality of life. Paramedics expressed a duty of care towards the patient's family. Relatives conveyed the importance of clear communication and acts of care performed by the ambulance crew, underscoring the ethical commitment that paramedics had towards patients' families. Paramedics described decision-making processes that relied on clinical guidelines, rather than personal values and beliefs; this sometimes led to moral distress.ConclusionNon-protocolised ethical considerations are important in paramedic decision-making about terminating CPR in OHCA events. While paramedics use established guidelines and processes to reach decisions that prevent patient harm, they experience moral distress when personal convictions clash with guidelines. Training around ethical reasoning and decision making may help paramedics reduce their moral distress and provide consistent and transparent decisions for patients and their families.

Project description:Background High-quality cardiopulmonary resuscitation (CPR) is associated with improved survival from out-of-hospital cardiac arrest and includes chest compression depth, chest compression rate, and chest compression fraction within international guideline recommendations. Previous studies have demonstrated divergent results of real-time feedback on CPR performance and patient outcomes. This study investigated the association between emergency medical service CPR quality and real-time CPR feedback for out-of-hospital cardiac arrest. Methods and Results This study collected out-of-hospital cardiac arrest data within the Capital Region of Denmark and compared CPR quality delivered by ambulance personnel. Data were collected in 2 consecutive phases from October 2018 to February 2020. Median chest compression depth was 6.0 cm (no feedback) and 5.9 cm (real-time feedback) (P=0.852). Corresponding proportion of guideline-compliant chest compressions for depth was 16.6% and 28.7%, respectively (P<0.001). Median chest compression rate per minute was 111 and 109 (P<0.001), respectively. Corresponding guideline adherence proportion for compression rate was 65.4% compared with 80.4% (P<0.001), respectively. Chest compression fraction was 78.9% compared with 81.9% (P<0.001), respectively. The combination of guideline-compliant chest compression depth and chest compression rate simultaneously was 8.5% (no feedback) versus 18.8% (feedback) (P<0.001). Improvements were not significant for return of spontaneous circulation (odds ratio [OR], 1.08 [95% CI, 0.84-1.39]), sustained return of spontaneous circulation (OR, 1.00 [95% CI, 0.77-1.31]), or survival to hospital discharge (OR, 0.91 [95% CI, 0.64-1.30]). Conclusions Real-time feedback was associated with improved guideline compliance for chest compression depth, rate, and fraction but not return of spontaneous circulation, sustained return of spontaneous circulation, or survival to hospital discharge.

Project description:We wanted to assess newborn life support (NLS) knowledge and guideline adherence, and provide strategies to improve (neonatal) resuscitation guideline adherence. Pediatricians completed 17 multiple-choice questions (MCQ). They performed a simulated NLS scenario, using a high-fidelity manikin. The literature was systematically searched for publications regarding guideline adherence. Forty-six pediatricians participated: 45 completed the MCQ, 34 performed the scenario. Seventy-one percent (median, IQR 56-82) of the MCQ were answered correctly. Fifty-six percent performed inflation breaths ≤ 60 s, 24% delivered inflation breaths of 2-3 s, and 85% used adequate inspiratory pressures. Airway patency was ensured 83% (IQR 76-92) of the time. Median events/min, compression rate, and percentage of effective compressions were 138/min (IQR 130-145), 120/min (IQR 114-120), and 38% (IQR 24-48), respectively. Other adherence percentages were temperature management 50%, auscultation of initial heart rate 100%, pulse oximeter use 94%, oxygen increase 74%, and correct epinephrine dose 82%. Ten publications were identified and used for our framework. The framework may inspire clinicians, educators, researchers, and guideline developers in their attempt to improve resuscitation guideline adherence. It contains many feasible strategies to enhance professionals' knowledge, skills, self-efficacy, and team performance, as well as recommendations regarding equipment, environment, and guideline development/dissemination.Conclusion: NLS guideline adherence among pediatricians needs improvement. Our framework is meant to promote resuscitation guideline adherence. What is Known: • Inadequate newborn life support (NLS) may contribute to (long-term) pulmonary and cerebral damage. • Video-based assessment of neonatal resuscitations has shown that deviations from the NLS guideline occur frequently; this assessment method has its audiovisual shortcomings. What is New: • The resuscitation quality metrics provided by our high-fidelity manikin suggest that the adherence of Dutch general pediatricians to the NLS guideline is suboptimal. • We constructed a comprehensive framework, containing multiple strategies to improve (neonatal) resuscitation guideline adherence.
