Factors influencing termination of resuscitation in children: a qualitative analysis

Verification of the termination of resuscitation rules in pediatric out-of-hospital cardiac arrest cases

Aim

Pediatric out-of-hospital cardiac arrest has an unfavorable prognosis; therefore, making accurate predictions of outcomes is crucial for tailoring treatment plans. The termination of resuscitation rules must accurately predict unfavorable outcomes. In this study, we aimed to assess if the current termination of resuscitation rules for adults can predict factors associated with unfavorable outcomes in pediatric out-of-hospital cardiac arrest and examine the relationship between these factors and unfavorable outcomes.

Methods

A retrospective nationwide cohort study of pediatric cases registered in the Japanese Association for Acute Medicine Multicenter Out-of-Hospital Cardiac Arrest Registry from June 1, 2014, to December 31, 2020, was conducted. The association between the current termination of resuscitation rules and outcomes, such as 30-day mortality and unfavorable 30-day neurological outcomes following out-of-hospital cardiac arrest, was evaluated.

Results

A total of 1,216 participants were included. The positive predictive value for predicting 30-day mortality for each termination of resuscitation rule exceeded 0.9. The specificity and positive predictive value for predicting unfavorable 30-day neurological outcomes were 1.00, indicating that no rules identified favorable outcomes. Factors such as no bystander witness, no return of spontaneous circulation before hospital arrival, no automated external defibrillator or defibrillator use, and no bystander cardiopulmonary resuscitation were associated with poor 30-day mortality and neurological outcomes.

Conclusion

Adult termination of resuscitation rules had a high positive predictive value for predicting pediatric out-of-hospital cardiac arrest. However, surviving cases make it challenging to use these rules for end-of-resuscitation decisions, indicating the need for identifying new rules to help predict neurological outcomes.

Characteristics of Pediatric In-Hospital Cardiac Arrests and Resuscitation Duration

Importance

Cardiopulmonary resuscitation (CPR) duration is associated with cardiac arrest survival.

Objectives

To describe characteristics associated with CPR duration among hospitalized children without return of circulation (ROC) (patient-level analysis) and determine whether hospital median CPR duration in patients without ROC is associated with survival (hospital-level analysis).

Design, Setting, and Participants

This retrospective cohort study of patients undergoing pediatric in-hospital CPR between January 1, 2000, and December 31, 2021, used data from the Get With the Guidelines-Resuscitation registry. Children receiving chest compressions for at least 2 minutes and/or defibrillation were included in the patient-level analysis. For the hospital-level analysis, sites with at least 20 total events and at least 5 events without ROC were included. Data were analyzed from December 1, 2022, to November 15, 2023.

Exposures

For the patient-level analysis, the exposure was CPR duration in patients without ROC. For the hospital-level analysis, the exposure was quartile of median CPR duration in events without ROC at each hospital.

Main Outcomes and Measures

For the patient-level analysis, outcomes were patient and event factors, including race and ethnicity and event location; we used a multivariable hierarchical linear regression model to assess factors associated with CPR duration in patients without ROC. For the hospital-level analysis, the main outcome was survival to discharge among all site events; we used a random intercept multivariable hierarchical logistic regression model to examine the association between hospital quartile of CPR duration and survival to discharge.

Results

Of 13 899 events, 3859 patients did not have ROC (median age, 7 months [IQR, 0 months to 7 years]; 2175 boys [56%]). Among event nonsurvivors, median CPR duration was longer in those with initial rhythms of bradycardia with poor perfusion (8.37 [95% CI, 5.70-11.03] minutes; P < .001), pulseless electrical activity (8.22 [95% CI, 5.44-11.00] minutes; P < .001), and pulseless ventricular tachycardia (6.17 [95% CI, 0.09-12.26] minutes; P = .047) (vs asystole). Shorter median CPR duration was associated with neonates compared with older children (-4.86 [95% CI, -8.88 to -0.84] minutes; P = .02), emergency department compared with pediatric intensive car7 e unit location (-4.02 [95% CI, -7.48 to -0.57] minutes; P = .02), and members of racial or ethnic minority groups compared with White patients (-3.67 [95% CI, -6.18 to -1.17]; P = .004). Among all CPR events, the adjusted odds of survival to discharge differed based on hospital quartile of median CPR duration among events without ROC; compared with quartile 1 (15.0-25.9 minutes), the adjusted odds ratio for quartile 2 (26.0-29.4 minutes) was 1.22 (95% CI, 1.09-1.36; P < .001); for quartile 3 (29.5-32.9 minutes), 1.23 (95% CI, 1.08-1.39; P = .002); and for quartile 4 (33.0-53.0 minutes), 1.04 (95% CI, 0.91-1.19; P = .58).

Conclusions and Relevance

In this retrospective cohort study of pediatric in-hospital CPR, several factors, including age and event location, were associated with CPR duration in event nonsurvivors. The odds of survival to discharge were lower for patients at hospitals with the shortest and longest median CPR durations among events without ROC. Further studies are needed to determine the optimal duration of CPR during pediatric in-hospital cardiac arrest and to provide training guidelines for resuscitation teams to eliminate disparities in resuscitation care.

Pediatric Cardiac Arrest and Resuscitation

Pediatric cardiac arrest in the emergency department is rare. We emphasize the importance of preparedness for pediatric cardiac arrest and offer strategies for the optimal recognition and care of patients in cardiac arrest and peri-arrest. This article focuses on both prevention of arrest and the key elements of pediatric resuscitation that have been shown to improve outcomes for children in cardiac arrest. Finally, we review changes to the American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care that were published in 2020.

Evolution of European Resuscitation and End-of-Life Practices from 2015 to 2019: A Survey-Based Comparative Evaluation

Background: In concordance with the results of large, observational studies, a 2015 European survey suggested variation in resuscitation/end-of-life practices and emergency care organization across 31 countries. The current survey-based study aimed to comparatively assess the evolution of practices from 2015 to 2019, especially in countries with “low” (i.e., average or lower) 2015 questionnaire domain scores. Methods: The 2015 questionnaire with additional consensus-based questions was used. The 2019 questionnaire covered practices/decisions related to end-of-life care (domain A); determinants of access to resuscitation/post-resuscitation care (domain B); diagnosis of death/organ donation (domain C); and emergency care organization (domain D). Responses from 25 countries were analyzed. Positive or negative responses were graded by 1 or 0, respectively. Domain scores were calculated by summation of practice-specific response grades. Results: Domain A and B scores for 2015 and 2019 were similar. Domain C score decreased by 1 point [95% confidence interval (CI): 1–3; p = 0.02]. Domain D score increased by 2.6 points (95% CI: 0.2–5.0; p = 0.035); this improvement was driven by countries with “low” 2015 domain D scores. In countries with “low” 2015 domain A scores, domain A score increased by 5.5 points (95% CI: 0.4–10.6; p = 0.047). Conclusions: In 2019, improvements in emergency care organization and an increasing frequency of end-of-life practices were observed primarily in countries with previously “low” scores in the corresponding domains of the 2015 questionnaire.

Pediatric Resuscitation

This article describes evidence-based nursing practices for detecting pediatric decompensation and prevention of cardiopulmonary arrest and outlines the process for effective and high-quality pediatric resuscitation and postresuscitation care. Primary concepts include pediatric decompensation signs and symptoms, pediatric resuscitation essential practices, and postresuscitation care, monitoring, and outcomes. Pediatric-specific considerations for family presence during resuscitation, ensuring good outcomes for medically complex children in community settings, and the role of targeted temperature management, continuous electroencephalography, and the use of extracorporeal membrane oxygenation in pediatric resuscitation are also discussed.

[Ethics of resuscitation and end of life decisions]

These European Resuscitation Council Ethics guidelines provide evidence-based recommendations for the ethical, routine practice of resuscitation and end-of-life care of adults and children. The guideline primarily focus on major ethical practice interventions (i.e. advance directives, advance care planning, and shared decision making), decision making regarding resuscitation, education, and research. These areas are tightly related to the application of the principles of bioethics in the practice of resuscitation and end-of-life care.
