Trends in the incidence and outcome of paediatric out-of-hospital cardiac arrest: A 17-year observational study

Heart Disease and Stroke Statistics-2020 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports on the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2020 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population, metrics to assess and monitor healthy diets, an enhanced focus on social determinants of health, a focus on the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors, implementation strategies, and implications of the American Heart Association's 2020 Impact Goals.

RESULTS

Each of the 26 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, healthcare administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

A descriptive analysis of the epidemiology and management of paediatric traumatic out-of-hospital cardiac arrest

AIM

Paediatric traumatic out-of-hospital cardiac arrest (OHCA) is a rare event with few survivors. We examined long-term trends in the incidence and outcomes of paediatric traumatic OHCA and explored the frequency and timing of intra-arrest interventions.

METHODS

We retrospectively analysed data from the Victorian Ambulance Cardiac Arrest Registry for cases involving traumatic OHCA in patients aged ≤16 years arresting between January 2000 to December 2017. Trends were assessed using linear regression and a non-parametric test for trend.

RESULTS

A total of 292 cases were attended by emergency medical services (EMS), of which 166 (56.9%) received an attempted resuscitation. The overall incidence of EMS-attended cases was 1.4 cases per 100,000 person-years, with no significant changes over time. Unadjusted outcomes also remained unchanged, with 23.5% achieving return of spontaneous circulation and 3.7% surviving to hospital discharge. The frequency of trauma-specific interventions increased between 2000-2005 and 2012-2017, including needle thoracostomy from 10.5% to 51.0% (p trend <0.001), crystalloid administration from 31.6% to 54.9% (p trend = 0.004) and blood administration from 0.0% to 6.3% (p trend = 0.01). The median time from emergency call to the delivery of interventions were: 12.9 min (IQR: 8.5, 20.0) for cardiopulmonary resuscitation, 19.7 min (IQR: 10.7, 39.6) for external haemorrhage control, 29.8 min (IQR: 22.0, 35.4) for crystalloid administration and 31.5 min (IQR: 21.0, 38.0) for needle thoracostomy.

CONCLUSION

The incidence and outcomes of paediatric traumatic OHCA remained unchanged over an 18 year period. Early correction of reversible causes by reducing delays to the delivery of trauma-specific interventions may yield additional survivors.

Relationship between institutional case volume and one-month survival among cases of paediatric out-of-hospital cardiac arrest

AIM

To evaluate volume-outcome relationship in paediatric out-of-hospital cardiac arrest (OHCA).

METHODS

This post hoc analysis of the SOS-KANTO 2012 study included data of paediatric OHCA patients <18 years old who were transported to the 53 emergency hospitals in the Kanto region of Japan between January 2012 and March 2013. Based on the paediatric OHCA case volume, the higher one-third of institutions (more than 10 paediatric OHCA cases during the study period) were defined as high-volume centres, the middle one-third institutions (6-10 cases) were defined as middle-volume centres and the lower one-third of institutions (less than 6 cases) were defined as low-volume centres. The primary outcome measurement was survival at 1 month after cardiac arrest. Multivariate logistic regression analysis for 1-month survival and paediatric OHCA case volume were performed after adjusting for multiple propensity scores. To estimate the multiple propensity score, we fitted a multinomial logistic regression model, which fell into one of the three groups as patient demographics and prehospital factors.

RESULTS

Among the eligible 282 children, 112, 82 and 88 patients were transported to the low-volume (36 institutions), middle-volume (11 institutions) and high-volume (6 institutions) centres, respectively. Transport to a high-volume centre was significantly associated with a better 1-month survival after adjusting for multiple propensity score (adjusted odds ratio, 2.55; 95% confidence interval, 1.05-6.17).

CONCLUSION

There may be a relationship between institutional case volume and survival outcomes in paediatric OHCA.
