In-hospital pediatric cardiac arrest in Spain

Trends in Incidences and Survival Rates in Pediatric In-Hospital Cardiopulmonary Resuscitation: A Korean Population-Based Study

Background Although the outcome of cardiopulmonary resuscitation (CPR) is still unsatisfactory, there are few studies about temporal trends of in-hospital CPR incidence and mortality. We aimed to evaluate nationwide trends of in-hospital CPR incidence and its associated risk factors and mortality in pediatric patients using a database of the Korean National Health Insurance between 2012 and 2018. Methods and Results We excluded neonates and neonatal intensive care unit admissions. Incidence of in-hospital pediatric CPR was 0.58 per 1000 admissions (3165 CPR/5 429 471 admissions), and the associated mortality was 50.4%. Change in CPR incidence according to year was not significant in an adjusted analysis (P=0.234). However, CPR mortality increased significantly by 6.6% every year in an adjusted analysis (P<0.001). Hospitals supporting pediatric critical care showed 37.7% lower odds of CPR incidence (P<0.001) and 27.5% lower odds of mortality compared with other hospitals in the adjusted analysis (P<0.001), and they did not show an increase in mortality (P for trend=0.882). Conclusions Temporal trends of in-hospital CPR mortality worsened in Korea, and the trends differed according to subgroups. Study results highlight the need for ongoing evaluation of CPR trends and for further CPR outcome improvement among hospitalized children.

Predictors and outcome of cardiac arrest in paediatric patients presenting to emergency medicine department of tertiary hospitals in Tanzania

Background

The survival of children who suffer cardiac arrest is poor. This study aimed to determine the predictors and outcome of cardiac arrest in paediatric patients presenting to an emergency department of a tertiary hospital in Tanzania.

Methodology

This was a prospective cohort study of paediatric patients > 1 month to ≤ 14 years presenting to Emergency Medicine Department of Muhimbili National Hospital (EMD) in Tanzania from September 2019 to January 2020 and triaged as Emergency and Priority. We enrolled consecutive patients during study periods where patients’ demographic and clinical presentation, emergency interventions and outcome were recorded. Logistic regression analysis was performed to identify the predictors of cardiac arrest.

Results

We enrolled 481 patients, 294 (61.1%) were males, and the median age was 2 years [IQR 1–5 years]. Among studied patients, 38 (7.9%) developed cardiac arrest in the EMD, of whom 84.2% were ≤ 5 years. Referred patients were over-represented among those who had an arrest (84.2%). The majority 33 (86.8%) of those who developed cardiac arrest died. Compromised circulation on primary survey (OR 5.9 (95% CI 2.1–16.6)), bradycardia for age on arrival (OR 20.0 (CI 1.6–249.3)), hyperkalemia (OR 8.2 (95% CI 1.4–47.7)), elevated lactate levels > 2 mmol/L (OR 5.2 (95% CI 1.4–19.7)), oxygen therapy requirement (OR 5.9 (95% CI 1.3–26.1)) and intubation within the EMD (OR 4.8 (95% CI 1.3–17.6)) were independent predictors of cardiac arrest.

Conclusion

Thirty-eight children developed cardiac arrest in the EMD, with a very high mortality. Those who arrested were more likely to present with signs of hypoxia, shock and acidosis, which suggest they were at later stage in their illness. Outcomes can be improved by strengthening the pre-referral care and providing timely critical management to prevent cardiac arrest.

Survival of pediatric patients after cardiopulmonary resuscitation for in-hospital cardiac arrest: a systematic review and meta-analysis

BACKGROUND

In-hospital cardiac arrest is a major public health issue. It is a serious condition; most probably end up with death within a few minutes even with corrective measures. However, cardiopulmonary resuscitation is expected to increase the probability of survival and prevent neurological disabilities in patients with cardiac arrest. Having a pooled prevalence of survival to hospital discharge after cardiopulmonary resuscitation is vital to develop strategies targeted to increase probability of survival among patients with cardiac arrest. Therefore, this systematic review and meta-analysis was aimed to assess the pooled prevalence of survival to hospital discharge among pediatric patients who underwent cardiopulmonary resuscitation for in-hospital cardiac arrest.

METHODS

PubMed, Google Scholar, and Cochrane review databases were searched. To have current (five-year) evidence, only studies published in 2016 to 2020 were included. The weighted inverse variance random-effects model at 95%CI was used to estimate the pooled prevalence of survival. Heterogeneity assessment, test of publication bias, and subgroup analyses were also employed accordingly.

RESULTS

Twenty-five articles with a total sample size of 28,479 children were included in the final analysis. The pooled prevalence of survival to hospital discharge was found to be 46% (95% CI = 43.0-50.0%; I2 = 96.7%; p < 0.001). Based on subgroup analysis by "continent" and "income level", lowest prevalence of pooled survival was observed in Asia (six studies; pooled survival =36.0% with 95% CI = 19.01-52.15%; I2 = 97.4%; p < 0.001) and in low and middle income countries (six studies, pooled survival = 34.0% with 95% CI = 17.0-51.0%, I2 = 97.67%, p < 0.001) respectively.

CONCLUSION

Although there was an extremely high heterogeneity among reported results (I2 = 96.7%), in this meta-analysis more than half of pediatric patients (54%) who underwent cardiopulmonary resuscitation for in-hospital cardiac arrest did not survived to hospital discharge. Therefore, developing further strategies and encouraging researches might be crucial.

Characteristics and Risk Factors for Mortality in Paediatric In-Hospital Cardiac Events in Singapore: Retrospective Single Centre Experience

Introduction: There is limited data on paediatric resuscitation outcomes in Asia. We aimed to describe outcomes of paediatric in-hospital cardiac arrests (IHCA) and peri-resuscitation factors associated with mortality in our institution. Materials and Methods: Using data from our hospital’s code registry from 2009 to 2014, we analysed all patients younger than 18 years of age with IHCA who required cardiopulmonary resuscitation (CPR). Exposure variables were obtained from clinical demographics, CPR and post-resuscitation data. Outcomes measured were: survival after initial CPR event and survival to hospital discharge. We analysed categorical and continuous variables with Fisher’s exact and Wilcoxon rank-sum tests respectively. Statistical significance was taken as P <0.05. Results: We identified 51 patients in the study period. Median age of patients was 1.9 (interquartile range [IQR]: 0.3, 5.5) years. Twenty-six (51%) patients had bradycardia as the first-recorded rhythm. The most common pre-existing medical condition was respiratory-related (n = 25, 48%). Thirty-eight (75%) achieved sustained return of spontaneous circulation, 24 (47%) survived to paediatric intensive care unit (PICU) discharge and 23 (45%) survived to hospital discharge. Risk factors for hospital mortality included: age, duration of CPR, adrenaline, calcium or bicarbonate administration during CPR, Paediatric Index of Mortality (PIM)-II scores, first recorded post-resuscitation pH and hyperglycaemia within 24 hours of resuscitation. Conclusion: We demonstrated an association between clinical demographics (age, PIM-II scores), CPR variables (duration of CPR and administration of adrenaline, calcium or bicarbonate) and post-resuscitation laboratory results (first recorded pH and hyperglycaemia within 24 hours) with PICU survival. The availability and quality of post-resuscitation care may have implications on survival after paediatric IHCA. Key words: Cardiopulmonary resuscitation, Child, Infant

The Success Rate of Pediatric In-Hospital Cardiopulmonary Resuscitation in Ahvaz Training Hospitals

Research Objective. This study determined the outcome of cardiopulmonary resuscitation (CPR) after in-hospital cardiac arrest and factors influencing it in two training hospitals in Ahvaz. Method. Patients hospitalized in the pediatric wards and exposed to CPR during hospital stay were included in the study (September 2013 to May 2014). The primary outcome of CPR was assumed to be the return of spontaneous circulation (ROSC) and the secondary outcome was assumed to be survival to discharge. The neurological outcome of survivors was assessed using the Pediatric Cerebral Performance Category (PCPC) method. Results. Of the 279 study participants, 138 patients (49.4%) showed ROSC, 81 patients (29%) survived for 24 hours after the CPR, and 33 patients (11.8%) survived to discharge. Of the surviving patients, 16 (48.5%) had favorable neurological outcome. The resuscitation during holidays resulted in fewer ROSC. Multivariate analysis showed that longer CPR duration, CPR by junior residents, growth deficiency, and prearrest vasoactive drug infusion were associated with decreased survival to discharge (p < 0.05). Infants and patients with respiratory disease had higher survival rates. Conclusion. The rate of successful CPR in our study was lower than rates reported by developed countries. However, factors influencing the outcome of CPR were similar. These results reflect the necessity of paying more attention to pediatric CPR training, postresuscitation conditions, and expansion of intensive care facilities.

Systematic review and meta-analysis of outcomes after cardiopulmonary arrest in childhood

BACKGROUND

Cardiopulmonary arrest in children is an uncommon event, and often fatal. Resuscitation is often attempted, but at what point, and under what circumstances do continued attempts to re-establish circulation become futile? The uncertainty around these questions can lead to unintended distress to the family and to the resuscitation team.

OBJECTIVES

To define the likely outcomes of cardiopulmonary resuscitation in children, within different patient groups, related to clinical features.

DATA SOURCES

MEDLINE, MEDLINE in-Process & Other non-Indexed Citations, EMBASE, Cochrane database of systematic reviews and Cochrane central register of trials, Database of Abstracts of Reviews of Effects (DARE), the Health Technology Assessment database, along with reference lists of relevant systematic reviews and included articles.

STUDY ELIGIBILITY CRITERIA

Prospective cohort studies which derive or validate a clinical prediction model of outcome following cardiopulmonary arrest.

PARTICIPANTS AND INTERVENTIONS

Children or young people (aged 0 - 18 years) who had cardiopulmonary arrest and received an attempt at resuscitation, excluding resuscitation at birth.

STUDY APPRAISAL AND SYNTHESIS METHODS

Risk of bias assessment developed the Hayden system for non-randomised studies and QUADAS2 for decision rules. Synthesis undertaken by narrative, and random effects meta-analysis with the DerSimonian-Laird estimator.

RESULTS

More than 18,000 episodes in 16 data sets were reported. Meta-analysis was possible for survival and one neurological outcome; others were reported too inconsistently. In-hospital patients (average survival 37.2% (95% CI 23.7 to 53.0%)) have a better chance of survival following cardiopulmonary arrest than out-of-hospital arrests (5.8% (95% CI 3.9% to 8.6%)). Better neurological outcome was also seen, but data were too scarce for meta-analysis (17% to 71% 'good' outcomes, compared with 2.8% to 3.2%).

LIMITATION

Lack of consistent outcome reporting and short-term neurological outcome measures limited the strength of conclusions that can be drawn from this review.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

There is a need to collaboratively, prospectively, collect potentially predictive data on these rare events to understand more clearly the predictors of survival and long-term neurological outcome.
