Effect of hospital characteristics on outcomes from pediatric cardiopulmonary resuscitation: a report from the national registry of cardiopulmonary resuscitation

Social Drivers of Health and Pediatric Extracorporeal Membrane Oxygenation Outcomes

BACKGROUND

Relationships between social drivers of health (SDoH) and pediatric health outcomes are highly complex with substantial inconsistencies in studies examining SDoH and extracorporeal membrane oxygenation (ECMO) outcomes. To add to this literature with emerging novel SDoH measures, and to address calls for institutional accountability, we examined associations between SDoH and pediatric ECMO outcomes.

METHODS

This single-center retrospective cohort study included children (<18 years) supported on ECMO (2012-2021). SDoH included Child Opportunity Index (COI), race, ethnicity, payer, interpreter requirement, urbanicity, and travel-time to hospital. COI is a multidimensional estimation of SDoH incorporating traditional (eg, income) and novel (eg, healthy food access) neighborhood attributes ([range 0-100] higher indicates healthier child development). Outcomes included in-hospital mortality, ECMO run duration, and length of stay (LOS).

RESULTS

540 children on ECMO (96%) had a calculable COI. In-hospital mortality was 44% with median run duration of 125 hours and ICU LOS 29 days. Overall, 334 (62%) had cardiac disease, 92 (17%) neonatal respiratory failure, 93 (17%) pediatric respiratory failure, and 21 (4%) sepsis. Median COI was 64 (interquartile range 32-81), 323 (60%) had public insurance, 174 (34%) were from underrepresented racial groups, 57 (11%) required interpreters, 270 (54%) had urban residence, and median travel-time was 89 minutes. SDoH including COI were not statistically associated with outcomes in univariate or multivariate analysis.

CONCLUSIONS

We observed no significant difference in pediatric ECMO outcomes according to SDoH. Further research is warranted to better understand drivers of inequitable health outcomes in children, and potential protective mechanisms.

Outcome of interhospital pediatric foreign body transfers

BACKGROUND

Children with foreign bodies are often transferred from general emergency departments (EDs) to children's hospitals for optimal management. Our objective was to describe the outcomes of interhospital pediatric foreign body transfers and examine factors associated with potentially avoidable transfers (PATs) in this cohort.

METHODS

We conducted a retrospective cohort study of children aged <18 years transferred to our hospital for the primary complaint of foreign body from January 1, 2020, to September 30, 2022. Data collected included demographics, diagnostic studies and interventions performed, and disposition. A transfer was considered a PAT if the patient was either discharged from the pediatric emergency department (PED), or from inpatient care within 24 h, did not require procedural sedation and any procedural intervention by a pediatric sub-specialist (other than a pediatric ED physician). Logistic regression analysis was performed to evaluate factors associated with PATs.

RESULTS

A total of 213 patients were analyzed based on eligibility criteria. The majority of patients were male (51.2%), pre-school age (59.2%), symptomatic (55.8%), and transferred from academic EDs (61%). Coins were the most common foreign bodies (30%), with the gastrointestinal tract (63.8%) being the most common location. Half of the non-respiratory and non-gastrointestinal foreign bodies were successfully removed in the PED. Over half (57.3%) of the patients were discharged from PED. Operative intervention was required in 82 (38.5%) patients, most commonly for coins (50%). 41.8% of transfers were deemed PATs. Presence of foreign body in the esophagus or respiratory tract (OR: 0.071, 95% CI: 0.025-0.200), symptoms at presentation (OR: 0.265, 95% CI: 0.130-0.542), magnet ingestions (OR: 0.208, 95% CI: 0.049-0.886) and transfers from community EDs (OR: 0.415, 95% CI: 0.194-0.885) were less likely associated with PATs. Button battery-related transfers were more likely associated with an avoidable transfer (OR: 6.681, 95% CI: 1.15-39.91).

CONCLUSIONS

PATs are relatively common among children transferred to a children's hospital for foreign bodies. Factors associated with PATs have been identified and may represent targets for interventions to avoid low value pediatric foreign body transfers.

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.

A Regional Intervention to Appoint Pediatric Emergency Care Coordinators in New England Emergency Departments

OBJECTIVE

The aim of this study was to describe our expansion of a Massachusetts grassroots initiative-to increase the appointment of pediatric emergency care coordinators (PECCs) in emergency departments (EDs)-to all 6 New England states.

METHODS

We conducted annual surveys of all EDs in New England from 2015 to 2020 regarding 2014 to 2019, respectively. Data collection included ED characteristics. The intervention from 2018 to 2019 relied on principles of self-organization and collaboration with local stakeholders including state Emergency Medical Services for Children agencies, American College of Emergency Physician state chapters, and Emergency Nursing Association state chapters to help encourage appointment of at least 1 PECC to every ED. Most ED leadership were contacted in person at regional meetings, by e-mail and/or telephone. We reached out to each individual ED to both educate and encourage action.

RESULTS

Survey response rates were greater than 85% in all years. From 2014 to 2016, less than 30% of New England EDs reported a PECC. In 2017, 51% of EDs in New England reported a PECC, whereas in 2019, 91% of New England EDs reported a PECC. All other ED characteristics remained relatively consistent from 2014 to 2019.

CONCLUSIONS

We successfully expanded a Massachusetts grassroots initiative to appoint PECCs to all of New England. Through individual outreach, and using principles of self-organization and creating collaborations with local stakeholders, we were able to increase the prevalence of PECCs in New England EDs from less than 30% to greater than 90%. This framework also led to the creation of a New England-wide PECC network and has fostered ongoing collaboration and communication throughout the region.

Risk Factors and Neurologic Outcomes Associated With Resuscitation in the Pediatric Intensive Care Unit

In the pediatric intensive care unit (PICU), cardiac arrest (CA) is rare but results in high rates of morbidity and mortality. A retrospective chart review of 223 patients who suffered from in-PICU CA was analyzed from January 2017 to December 2020. Outcomes at discharge were evaluated using pediatric cerebral performance category (PCPC). Return of spontaneous circulation was attained by 167 (74.8%) patients. In total, only 58 (25%) patients survived to hospital discharge, and 49 (21.9%) of the cohort had good neurologic outcomes. Based on multivariate logistic regression analysis, vasoactive-inotropic drug usage before CA, previous PCPC scale >2, underlying hemato-oncologic disease, and total time of CPR were risk factors associated with poor outcomes. Furthermore, we determined the cutoff value of duration of CPR in predicting poor neurologic outcomes and in-hospital mortality in patients caused by in-PICU CA as 17 and 23.5 min respectively.

Racial disparities in survival outcomes following pediatric in-hospital cardiac arrest

BACKGROUND

Among adults with in-hospital cardiac arrest (IHCA), overall survival is lower in black patients compared to white patients. Data regarding racial differences in survival for pediatric IHCA are unknown.

METHODS

Using 2000-2017 data from the American Heart Association Get With the Guidelines-Resuscitation® registry, we identified children >24 h and <18 years of age with IHCA due to an initial pulseless rhythm. We used generalized estimation equation to examine the association of black race with survival to hospital discharge, return of spontaneous circulation (ROSC), and favorable neurologic outcome at discharge.

RESULTS

Overall, 2940 pediatric patients (898 black, 2042 white) at 224 hospitals with IHCA were included. The mean age was 3.0 years, 57% were male and 16% had an initial shockable rhythm. Age, sex, interventions in place at the time of arrest and cardiac arrest characteristics did not differ significantly by race. The overall survival to discharge was 36.9%, return of spontaneous circulation (ROSC) was 73%, and favorable neurologic survival was 20.8%. Although black race was associated with lower rates of ROSC compared to white patients (69.5% in blacks vs. 74.6% in whites; risk-adjusted OR 0.79, 95% CI 0.67-0.94, P = 0.016), black race was not associated with survival to discharge (34.7% in blacks vs. 37.8% in whites; risk-adjusted OR 0.96, 95% CI 0.80-1.15, P = 0.68) or favorable neurologic outcome (18.7% in blacks vs. 21.8% in whites, risk-adjusted OR 0.98, 95% CI 0.80-1.20, p = 0.85).

CONCLUSIONS

In contrast to adults, we did not find evidence for racial differences in survival outcomes following IHCA among children.

The landscape of paediatric in-hospital cardiac arrest in the United Kingdom National Cardiac Arrest Audit

AIM

To report the patient characteristics and clinical outcome of paediatric in-hospital cardiac arrest in the United Kingdom (UK) National Cardiac Arrest Audit (NCAA) database.

METHODS

Analysis of all recorded paediatric cardiac arrests in the NCAA dataset over a seven-year period ending on 31 December 2018, within acute children's hospitals (including standalone paediatric hospitals and hospitals with tertiary paediatric services) and acute general hospitals participating in NCAA. In this period 1456 patients (with 1580 events), 1 month to 16 years of age, received chest compressions and/or defibrillation and were attended by a hospital-based resuscitation team in response to an emergency call. The main outcome measure was survival to discharge.

RESULTS

For this cohort of paediatric in-hospital cardiac arrest patients the overall rates of sustained return of spontaneous circulation (ROSC) were 69.1% with unadjusted survival to hospital discharge of 54.2%. The presenting rhythm was shockable in 4.3% of events and non-shockable in 82.1% (remainder undetermined); rates of survival to hospital discharge associated with these rhythms were 63.9% and 51.7%. A difference in outcomes was observed between Children's hospitals and acute general hospitals with ROSC rates of 79.1% and 55.5% respectively and survival to hospital discharge rates of 57.7% and 49.3% respectively.

CONCLUSIONS

These first results from the NCAA database describing the outcome of paediatric in-hospital cardiac arrest in UK hospitals will serve as a benchmark from which to assess the future impact of changes in service delivery, organisation and treatment for in-hospital cardiac arrest in young people. Outcomes for specialist paediatric centres should be studied further as higher rates of ROSC and survival to hospital discharge were observed.

Characterizing Avoidable Transfer Admissions in Infants Hospitalized for Bronchiolitis

OBJECTIVES

The appropriateness of interfacility transfer admissions for bronchiolitis to pediatric centers is uncertain. We characterized avoidable transfer admissions for bronchiolitis. We hypothesized that a higher proportion of hospitalized infants transferred from a community emergency department (ED) or hospital (transfer admission) would be discharged within 48 hours with little or no intervention, compared with direct admissions from an enrolling ED (nontransfer admission).

METHODS

We analyzed a 17-center, prospective infant cohort (age <1 year) hospitalized for bronchiolitis (2011-2014). An avoidable transfer admission (primary outcome) was hospitalization for <48 hours without an intervention for severe illness in which a pediatric specialist could be beneficial (oxygen, advanced airway management, life support). Parenteral fluids and routine medications were excluded. We compared admissions by patient, ED, inpatient, and transferring hospital characteristics to identify factors associated with avoidable transfer admissions. Multivariable logistic regression was used to identify predictors of avoidable transfer admission.

RESULTS

Among 1007 infants, 558 (55%) were nontransfer admissions, 164 (16%) were transfer admissions, and 204 (20%) were referrals from clinics; 81 (8%) were missing referral type. Significantly fewer transferred infants were hospitalized for <48 hours with little or no intervention (40 of 164; 24% [95% confidence interval 18%-32%]) than nontransferred infants (199 of 558; 36% [95% confidence interval 32%-40%]; P = .007). Avoidable transfer admissions were more likely to be children of color, have nonprivate insurance, receive fewer ED interventions, and originate from small EDs. A multivariable model revealed that minority race and/or ethnicity, normal oxygenation, and small ED transfers increased odds of avoidable transfer admission.

CONCLUSIONS

Although most transferred infants hospitalized for bronchiolitis required interventions for severe illness, 1 in 4 admissions were potentially avoidable.

Lidocaine versus amiodarone for pediatric in-hospital cardiac arrest: An observational study

BACKGROUND

Lidocaine and amiodarone are both included in the pediatric cardiac arrest guidelines as treatments of shock-refractory ventricular fibrillation or pulseless ventricular tachycardia, although there is limited evidence to support this recommendation.

METHODS

In this cohort study from the Get With The Guidelines - Resuscitation registry, we included pediatric patients (≤18 years) with an in-hospital cardiac arrest between 2000 and 2018, who presented with an initial or subsequent shockable rhythm (ventricular fibrillation and pulseless ventricular tachycardia). Patients receiving amiodarone were matched to patients receiving lidocaine based on a propensity score, calculated from multiple patient, event, and hospital characteristics.

RESULTS

A total of 365 patients were available for the analysis, of which 180 (49%) patients were matched on the propensity score. The median age in the raw cohort was 6 (quartiles, 0.5-14) years, 164 (45%) patients were female, and 238 (65%) patients received an antiarrhythmic for an initial shockable rhythm. In the matched cohort, there were no statistically significant differences between patients receiving lidocaine compared to amiodarone in return of spontaneous circulation (RR, 0.99 [95%CI, 0.82-1.19]; p = 0.88), survival to 24 h (RR, 1.02 [95%CI, 0.76-1.38]; p = 0.88), survival to hospital discharge (RR, 1.01 [95%CI, 0.63-1.63]; p = 0.96), and favorable neurological outcome (RR, 0.65 [95%CI, 0.35-1.21]; p = 0.17). The results remained consistent in multiple sensitivity analyses.

CONCLUSIONS

In children with cardiac arrest receiving antiarrhythmics for a shockable rhythm, there was no significant difference in clinical outcomes between those receiving lidocaine compared to amiodarone.

Outcomes of paediatric out-of-hospital cardiac arrest according to hospital characteristic defined by the annual number of paediatric patients with invasive mechanical ventilation: A nationwide study in Japan

AIM

We examined whether outcomes of paediatric out-of-hospital cardiac arrest (OHCA) are associated with a hospital characteristic defined by the annual number of invasive mechanical ventilation cases, suggesting hospitals' experience in caring for severely ill paediatric patients.

METHOD

We analysed the Japanese Diagnosis Procedure Combination database from 2010 to 2017. We identified children (<18 years) with OHCA and post-resuscitation intensive care (defined as invasive mechanical ventilation and/or catecholamine infusion). Hospitals were divided into four groups by mean annual number of paediatric cases involving invasive mechanical ventilation. The primary outcome was in-hospital mortality, and the secondary outcome was unfavourable outcomes (death or medical care dependency at discharge). Multivariable logistic regression analyses were conducted to examine the relationship between hospitals' experience and outcomes.

RESULTS

We included 2540 paediatric OHCA patients from 385 institutions. Overall in-hospital mortality was 62.4%, with rates of 69.6%, 61.3%, 61.8%, and 57.0% in hospitals with low (≤48 cases/year), low-intermediate (48-110), high-intermediate (110-164), and high (>164) experience levels (P < .001), respectively. Compared to hospitals with low experience, adjusted odds ratios (95% confidence interval) for hospitals with low-intermediate, high-intermediate, and high experience were as follows: primary outcome: 0.64 (0.40-1.01), 0.67 (0.42-1.05), and 0.46 (0.31-0.70), respectively; secondary outcome: 0.93 (0.55-1.57), 0.95 (0.63-1.43), and 0.67 (0.46-0.96), respectively.

CONCLUSION

Japanese hospitals with higher experience in caring for severely ill paediatric patients showed lower mortality for paediatric OHCA. This fact should be considered by the Emergency Medical Systems when deciding transport strategy.

Pediatric cardiac arrest in the emergency department: Outcome is related to the time of admission

Objectives:

Nights and weekends represent a potentially high-risk time for pediatric cardiac arrest (CA) patients in emergency departments. Data regarding night or weekend arrest and its impact on outcomes is controversial. The purpose of this study was to determine the relationship between cardiopulmonary resuscitation during the various emergency department shifts and survival to discharge.

Methods:

We conducted a retrospective, observational study of patients who had visited our Emergency Department for CAs from January 2014 to December 2016. Medical records and patient characteristics of 67 children with CA were retrieved from patient admission files.

Results:

The mean age was 54.7±7.3 months and 59% were male. Rates of survival to discharge 35% (11/31) within working hours’ vs. out of working hours 3% (1/36). Among the CAs presenting to the emergency department, the survival rates were higher for working hours than for non-working hours (OR: 37.6 (2.62-539.7), p: 008). The rate of return of spontaneous circulation within working hours was higher than that of non-working hours (71% vs.19%) (p<0.001). Patients who received chest compression for more than 10 minutes had the lowest survival rate (2%) (p<0.001), whereas better outcome was associated with in-hospital CA, younger age (less than 12 months) and respiratory failure.

Conclusion:

Survival rates from pediatric CAs were significantly lower during non-working hours. Poor outcome was associated with prolonged cardiopulmonary resuscitation, out of hospital CA and older age.

The Association of Hospital Rate of Delayed Epinephrine Administration With Survival to Discharge for Pediatric Nonshockable In-Hospital Cardiac Arrest

OBJECTIVES

To evaluate the variation of hospital rates of delayed epinephrine administration in pediatric patients with nonshockable in-hospital cardiac arrest, and the association of those rates with event, 24-hour, and overall survival to hospital discharge.

DESIGN

A retrospective evaluation was performed. Delayed epinephrine was defined as greater than 5 minutes between the time the need for chest compressions was identified and epinephrine was administered. The main outcome was the association of hospital rate of delayed epinephrine administration with survival to hospital discharge. Secondary outcomes were event and 24-hour survival. Evaluation used hierarchical logistic regression and included 13 patient/event-level and seven hospital-level factors.

SETTING

Hospitals with greater than 6 months data in the American Heart Association's Get With the Guidelines-Resuscitation registry (2000-2016) and greater than or equal to five total pediatric cardiac arrests with nonshockable rhythm.

PATIENTS

Children less than 18 years old with index nonshockable in-hospital cardiac arrest treated with greater than or equal to one epinephrine dose.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

One-thousand four-hundred sixty-two patients at 69 hospitals were included: 218 patients (14.9%) had epinephrine delay rates ranging from 0% to 80% of events (median, 15.6%; interquartile range, 7-25%). The median and interquartile range of hospital level delay was 16% (7-25%). Patient/event-level predictors of delayed epinephrine were asystole (odds ratio, 1.54 [95% CI, 1.10-2.16]) and insertion of an endotracheal tube (odds ratio, 1.86 [95% CI, 1.27-2.73]). Hospital size less than 200 compared with greater than or equal to 500 beds (odds ratio, 3.07 [95% CI, 1.22-7.73]) and ICU location (odds ratio, 0.51 [95% CI, 0.36-0.74]) were associated with epinephrine delay rates. After adjustment, increasing quartiles of epinephrine delay were associated with lower patient and hospital-level return of spontaneous circulation (p = 0.019, p = 0.006) and 24-hour survival (p = 0.018, p = 0.002) respectively, but not survival to discharge (p = 0.20, p = 0.24).

CONCLUSIONS

Delayed epinephrine administration following pediatric nonshockable in-hospital cardiac arrest varies significantly between hospitals. Hospitals with higher rates of delayed epinephrine administration had worse patient- and hospital-level outcomes after adjusting for multiple patient- and hospital-level factors. Delayed epinephrine administration may directly contribute to increased mortality risk and/or may be a marker of unmeasured elements of hospital resuscitation performance.

Dispatcher-assisted cardiopulmonary resuscitation for paediatric out-of-hospital cardiac arrest: A structured evaluation of communication issues using the SACCIA® safe communication typology

AIM

To evaluate communication issues during dispatcher-assisted cardiopulmonary resuscitation (DACPR) for paediatric out-of-hospital cardiac arrest in a structured manner to facilitate recommendations for training improvement.

METHODS

A retrospective observational study evaluated DACPR communication issues using the SACCIA^® Safe Communication typology (Sufficiency, Accuracy, Clarity, Contextualization, Interpersonal Adaptation). Telephone recordings of 31 cases were transcribed verbatim and analysed with respect to encoding, decoding and transactional communication issues.

RESULTS

Sixty SACCIA communication issues were observed in the 31 cases, averaging 1.9 issues per case. A majority of the issues were related to sufficiency (35%) and accuracy (35%) of communication between dispatcher and caller. Situation specific guideline application was observed in CPR practice, (co)counting and methods of compressions.

CONCLUSION

This structured evaluation identified specific issues in paediatric DACPR communication. Our training recommendations focus on situation and language specific guideline application and moving beyond verbal communication by utilizing the smart phone's functions. Prospective efforts are necessary to follow-up its translation into better paediatric DACPR outcomes.

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.

Association Between Time to Defibrillation and Survival in Pediatric In-Hospital Cardiac Arrest With a First Documented Shockable Rhythm

IMPORTANCE

Delayed defibrillation (>2 minutes) in adult in-hospital cardiac arrest (IHCA) is associated with worse outcomes. Little is known about the timing and outcomes of defibrillation in pediatric IHCA.

OBJECTIVE

To determine whether time to first defibrillation attempt in pediatric IHCA with a first documented shockable rhythm is associated with survival to hospital discharge.

DESIGN, SETTING, AND PARTICIPANTS

In this cohort study, data were obtained from the Get With The Guidelines-Resuscitation national registry between January 1, 2000, and December 31, 2015, and analyses were completed by October 1, 2017. Participants were pediatric patients younger than 18 years with an IHCA and a first documented rhythm of pulseless ventricular tachycardia or ventricular fibrillation and at least 1 defibrillation attempt.

EXPOSURES

Time between loss of pulse and first defibrillation attempt.

MAIN OUTCOMES AND MEASURES

The primary outcome was survival to hospital discharge. Secondary outcomes were return of circulation, 24-hour survival, and favorable neurologic outcome at hospital discharge.

RESULTS

Among 477 patients with a pulseless shockable rhythm (median [interquartile range] age, 4 years [3 months to 14 years]; 285 [60%] male), 338 (71%) had a first defibrillation attempt at 2 minutes or less after pulselessness. Children were less likely to be shocked in 2 minutes or less for ward vs intensive care unit IHCAs (48% [11 of 23] vs 72% [268 of 371]; P = .01]). Thirty-eight percent (179 patients) survived to hospital discharge. The median (interquartile range) reported time to first defibrillation attempt was 1 minute (0-3 minutes) in both survivors and nonsurvivors. Time to first defibrillation attempt was not associated with survival in unadjusted analysis (risk ratio [RR] per minute increase, 0.96; 95% CI, 0.92-1.01; P = .15) or adjusted analysis (RR, 0.99; 95% CI, 0.94-1.06; P = .86). There was no difference in survival between those with a first defibrillation attempt in 2 minutes or less vs more than 2 minutes in unadjusted analysis (132 of 338 [39%] vs 47 of 139 [34%]; RR, 0.87; 95% CI, 0.66-1.13; P = .29) or multivariable analysis (RR, 0.99; 95% CI, 0.75-1.30; P = .93). Time to first defibrillation attempt was also not associated with secondary outcome measures.

CONCLUSIONS AND RELEVANCE

In contrast to published adult IHCA and pediatric out-of-hospital cardiac arrest data, no significant association was observed between time to first defibrillation attempt in pediatric IHCA with a first documented shockable rhythm and survival to hospital discharge.

Cardiopulmonary Resuscitation in Infants and Children With Cardiac Disease: A Scientific Statement From the American Heart Association

Cardiac arrest occurs at a higher rate in children with heart disease than in healthy children. Pediatric basic life support and advanced life support guidelines focus on delivering high-quality resuscitation in children with normal hearts. The complexity and variability in pediatric heart disease pose unique challenges during resuscitation. A writing group appointed by the American Heart Association reviewed the literature addressing resuscitation in children with heart disease. MEDLINE and Google Scholar databases were searched from 1966 to 2015, cross-referencing pediatric heart disease with pertinent resuscitation search terms. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. The recommendations in this statement concur with the critical components of the 2015 American Heart Association pediatric basic life support and pediatric advanced life support guidelines and are meant to serve as a resuscitation supplement. This statement is meant for caregivers of children with heart disease in the prehospital and in-hospital settings. Understanding the anatomy and physiology of the high-risk pediatric cardiac population will promote early recognition and treatment of decompensation to prevent cardiac arrest, increase survival from cardiac arrest by providing high-quality resuscitations, and improve outcomes with postresuscitation care.

Cardiac Arrest Survival in Pediatric and General Emergency Departments

BACKGROUND AND OBJECTIVES

Pediatric out-of-hospital cardiac arrest (OHCA) has a low rate of survival to hospital discharge. Understanding whether pediatric emergency departments (EDs) have higher survival than general EDs may help identify ways to improve care for all patients with OHCA. We sought to determine if OHCA survival differs between pediatric and general EDs.

METHODS

We used the 2009-2014 Nationwide Emergency Department Sample to study children under 18 with cardiac arrest. We compared pediatric EDs (those with >75% pediatric visits) to general EDs on the outcome of survival to hospital discharge or transfer. We determined unadjusted and adjusted survival, accounting for age, region, and injury severity. Analyses were stratified by nontraumatic versus traumatic cause.

RESULTS

The incidences of nontraumatic and traumatic OHCA were 7.91 (95% confidence interval [CI]: 7.52-8.30) and 2.67 (95% CI: 2.49-2.85) per 100 000 person years. In nontraumatic OHCA, unadjusted survival was higher in pediatric EDs than general EDs (33.8% vs 18.9%, P < .001). The adjusted odds ratio of survival in pediatric versus general EDs was 2.2 (95% CI: 1.7-2.8). Children with traumatic OHCA had similar survival in pediatric and general EDs (31.7% vs 26.1%, P = .14; adjusted odds ratio = 1.3 [95% CI: 0.8-2.1]).

CONCLUSIONS

In a nationally representative sample, survival from nontraumatic OHCA was higher in pediatric EDs than general EDs. Survival did not differ in traumatic OHCA. Identifying the features of pediatric ED OHCA care leading to higher survival could be translated into improved survival for children nationally.

Can Telemedicine Improve Adherence to Resuscitation Guidelines for Critically Ill Children at Community Hospitals? A Randomized Controlled Trial Using High-Fidelity Simulation

OBJECTIVES

Children transferred from community hospitals lacking specialized pediatric care are more seriously ill than those presenting to pediatric centers. Pediatric consultation and adherence to management guidelines improve outcomes. The aims of the study were (1) to assess whether telemedicine consultation in critical situations is feasible and (2) to compare the impact of pediatric critical care medicine (PCCM) consultation via telemedicine versus telephone on community hospital adherence to resuscitation guidelines through a randomized controlled telemedicine trial.

METHODS

In situ, high-fidelity simulation scenarios of critically ill children presenting to a community hospital and progressing to cardiopulmonary arrest were performed. Scenarios were randomized to PCCM consultation via telephone (control) or telemedicine (intervention). Primary outcome measure was proportion of teams who successfully defibrillated in 180 seconds or less from presentation of pulseless ventricular tachycardia.

RESULTS

The following 30 scenarios were completed: 15 control and 15 intervention. Only 11 (37%) of 30 teams, defibrillated in 180 seconds or less from presentation of pulseless ventricular tachycardia; control: 6 (40%) of 15 versus intervention: 5 (33%) of 15, P = 0.7. Request for or use of backboard during cardiopulmonary resuscitation occurred in 24 (80%) of 30 scenarios; control: 9 (60%) of 15 versus intervention: 15 (100%) of 15, P = 0.006. Request for or use of stepstool during cardiopulmonary resuscitation occurred in 6 (20%) of 30 scenarios; control: 1 (7%) of 15 versus intervention: 5 (33%) of 15, P = 0.07.

CONCLUSIONS

This study demonstrates the feasibility of using telemedicine to support acute management of children who present to community hospitals. Neither study arm adhered to current resuscitation guidelines and telemedicine consultation with PCCM experts was not associated with improvement. However, further research on optimizing telemedicine impact on the quality of pediatric care at community hospitals is warranted.

Association Between Tracheal Intubation During Pediatric In-Hospital Cardiac Arrest and Survival

IMPORTANCE

Tracheal intubation is common during pediatric in-hospital cardiac arrest, although the relationship between intubation during cardiac arrest and outcomes is unknown.

OBJECTIVE

To determine if intubation during pediatric in-hospital cardiac arrest is associated with improved outcomes.

DESIGN, SETTING, AND PARTICIPANTS

Observational study of data from United States hospitals in the Get With The Guidelines-Resuscitation registry. Pediatric patients (<18 years) with index in-hospital cardiac arrest between January 2000 and December 2014 were included. Patients who were receiving assisted ventilation, had an invasive airway in place, or both at the time chest compressions were initiated were excluded.

EXPOSURES

Tracheal intubation during cardiac arrest .

MAIN OUTCOMES AND MEASURES

The primary outcome was survival to hospital discharge. Secondary outcomes included return of spontaneous circulation and neurologic outcome. A favorable neurologic outcome was defined as a score of 1 to 2 on the pediatric cerebral performance category score. Patients being intubated at any given minute were matched with patients at risk of being intubated within the same minute (ie, still receiving resuscitation) based on a time-dependent propensity score calculated from multiple patient, event, and hospital characteristics.

RESULTS

The study included 2294 patients; 1308 (57%) were male, and all age groups were represented (median age, 7 months [25th-75th percentiles, 21 days, 4 years]). Of the 2294 included patients, 1555 (68%) were intubated during the cardiac arrest. In the propensity score-matched cohort (n = 2270), survival was lower in those intubated compared with those not intubated (411/1135 [36%] vs 460/1135 [41%]; risk ratio [RR], 0.89 [95% CI, 0.81-0.99]; P = .03). There was no significant difference in return of spontaneous circulation (770/1135 [68%] vs 771/1135 [68%]; RR, 1.00 [95% CI, 0.95-1.06]; P = .96) or favorable neurologic outcome (185/987 [19%] vs 211/983 [21%]; RR, 0.87 [95% CI, 0.75-1.02]; P = .08) between those intubated and not intubated. The association between intubation and decreased survival was observed in the majority of the sensitivity and subgroup analyses, including when accounting for missing data and in a subgroup of patients with a pulse at the beginning of the event.

CONCLUSIONS AND RELEVANCE

Among pediatric patients with in-hospital cardiac arrest, tracheal intubation during cardiac arrest compared with no intubation was associated with decreased survival to hospital discharge. Although the study design does not eliminate the potential for confounding, these findings do not support the current emphasis on early tracheal intubation for pediatric in-hospital cardiac arrest.

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.

Association Between Facility Type During Pediatric Inpatient Rehabilitation and Functional Outcomes

OBJECTIVE

To compare functional outcomes between children receiving inpatient rehabilitation at children's hospitals and those at other facilities.

DESIGN

Retrospective cohort study.

SETTING

Inpatient rehabilitation facilities.

PARTICIPANTS

Children (N=28,793) aged 6 months to 18 years who received initial inpatient rehabilitation.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Total, cognitive, and motor developmental functional quotients (DFQs; which is the WeeFIM score divided by age-adjusted norms and multiplied by 100) at discharge from inpatient rehabilitation and WeeFIM efficiency (the change in WeeFIM score from admission to discharge divided by the length of the rehabilitation stay), adjusting for age, sex, race, insurance, region, admission function, impairment type, discharge year, and length of stay.

RESULTS

A total of 12,732 children received rehabilitation at 25 children's hospitals and 16,061 at 36 other facilities (general hospitals or freestanding rehabilitation hospitals). Adjusting for clustering by facility, patients at children's hospitals had a lower cognitive DFQ at admission (difference between children's hospitals and other facility types, -3.8; 95% confidence interval [CI], -7.7 to -0.1), a shorter length of stay (median, 16d vs 22d; P<.001), and a higher WeeFIM efficiency (difference, 0.63; 95% CI, 0.25-1.00) than did children at other facility types. Rehabilitation in a children's hospital was independently associated with a higher discharge cognitive DFQ (regression coefficient, 2.3; 95% CI, 0.3-4.2) and more efficient rehabilitation admissions (regression coefficient, 0.3; 95% CI, 0.1-0.6).

CONCLUSIONS

Children who receive inpatient rehabilitation at children's hospitals have more efficient inpatient rehabilitation admissions, a shorter median length of stay, and a slight improvement in cognitive function than do children at other facility types.

Cardiopulmonary Resuscitation in Children With In-Hospital and Out-of-Hospital Cardiopulmonary Arrest: Multicenter Study From Turkey

OBJECTIVES

The objectives of this study were to determine the causes, location of cardiopulmonary arrest (CPA) in children, and demographics of cardiopulmonary resuscitation (CPR) in Turkish pediatric emergency departments and pediatric intensive care units (PICUs) and to determine survival rates and morbidities for both in-hospital and out-of-hospital CPA.

METHODS

This multicenter descriptive study was conducted prospectively between January 15 and July 15, 2011, at 18 centers (15 PICUs, 3 pediatric emergency departments) in Turkey.

RESULTS

During the study period, 239 children had received CPR. Patients' average age was 42.4 (SD, 58.1) months. The most common cause of CPA was respiratory failure (119 patients [49.8%]). The location of CPA was the PICU in 168 (68.6%), hospital wards in 43 (18%), out-of-hospital in 24 (10%), and pediatric emergency department in 8 patients (3.3%). The CPR duration was 30.7 (SD, 23.6) minutes (range, 1-175 minutes) and return of spontaneous circulation was achieved in 107 patients (44.8%) after the first CPR. Finally, 58 patients (24.2%) were discharged from hospital; survival rates were 26% and 8% for in-hospital and out-of-hospital CPA, respectively (P = 0.001). Surviving patients' average length of hospital stay was 27.4 (SD, 39.2) days. In surviving patients, 19 (32.1%) had neurologic disability.

CONCLUSION

Pediatric CPA in both the in-hospital and out-of-hospital setting has a poor outcome.

Time to Epinephrine and Survival After Pediatric In-Hospital Cardiac Arrest

IMPORTANCE

Delay in administration of the first epinephrine dose is associated with decreased survival among adults after in-hospital, nonshockable cardiac arrest. Whether this association is true in the pediatric in-hospital cardiac arrest population remains unknown.

OBJECTIVE

To determine whether time to first epinephrine dose is associated with outcomes in pediatric in-hospital cardiac arrest.

DESIGN, SETTING AND PARTICIPANTS

We performed an analysis of data from the Get With the Guidelines-Resuscitation registry. We included US pediatric patients (age <18 years) with an in-hospital cardiac arrest and an initial nonshockable rhythm who received at least 1 dose of epinephrine. A total of 1558 patients (median age, 9 months [interquartile range [IQR], 13 days-5 years]) were included in the final cohort.

EXPOSURE

Time to epinephrine, defined as time in minutes from recognition of loss of pulse to the first dose of epinephrine.

MAIN OUTCOMES AND MEASURES

The primary outcome was survival to hospital discharge. Secondary outcomes included return of spontaneous circulation (ROSC), survival at 24 hours, and neurological outcome. A favorable neurological outcome was defined as a score of 1 to 2 on the Pediatric Cerebral Performance Category scale.

RESULTS

Among the 1558 patients, 487 (31.3%) survived to hospital discharge. The median time to first epinephrine dose was 1 minute (IQR, 0-4; range, 0-20; mean [SD], 2.6 [3.4] minutes). Longer time to epinephrine administration was associated with lower risk of survival to discharge in multivariable analysis (multivariable-adjusted risk ratio [RR] per minute delay, 0.95 [95% CI, 0.93-0.98]). Longer time to epinephrine administration was also associated with decreased risk of ROSC (multivariable-adjusted RR per minute delay, 0.97 [95% CI, 0.96-0.99]), decreased risk of survival at 24 hours (multivariable-adjusted RR per minute delay, 0.97 [95% CI, 0.95-0.99]), and decreased risk of survival with favorable neurological outcome (multivariable-adjusted RR per minute delay, 0.95 [95% CI, 0.91-0.99]). Patients with time to epinephrine administration of longer than 5 minutes (233/1558) compared with those with time to epinephrine of 5 minutes or less (1325/1558) had lower risk of in-hospital survival to discharge (21.0% [49/233] vs 33.1% [438/1325]; multivariable-adjusted RR, 0.75 [95% CI, 0.60-0.93]; P = .01).

CONCLUSIONS AND RELEVANCE

Among children with in-hospital cardiac arrest with an initial nonshockable rhythm who received epinephrine, delay in administration of epinephrine was associated with decreased chance of survival to hospital discharge, ROSC, 24-hour survival, and survival to hospital discharge with a favorable neurological outcome.

Pediatric Extracorporeal Membrane Oxygenation: An Introduction for Emergency Medicine Physicians

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) therapy has supported critically ill pediatric patients in the intensive care unit setting with cardiac and respiratory failure. This therapy is beginning to transition to the emergency department setting.

OBJECTIVE OF REVIEW

This article describes the fundamentals of ECMO and familiarizes the emergency medicine physician with its use in critically ill pediatric patients.

DISCUSSION

ECMO can be utilized as either venoarterial (VA) or venovenous (VV), to support oxygenation and perfusion in respiratory failure, sepsis, cardiac arrest, and environmental hypothermia.

Cardiopulmonary resuscitation for in-hospital events in the emergency department: A comparison of adult and pediatric outcomes and care processes

OBJECTIVES

To compare outcomes from in-hospital cardiopulmonary resuscitation (CPR) in the emergency department (ED) for pediatric and adult patients and to identify factors associated with differences in outcomes between children and adults.

METHODS

Retrospective analysis of the Get With The Guidelines--Resuscitation database from January 1, 2000 to September 30, 2010. All patients with CPR initiated in the ED requiring chest compressions for ≥ 2 min were eligible; trauma patients were excluded. Patients were divided into children (<18 yo) and adults (≥ 18 yo). Patient, event, treatment, and hospital factors were analyzed for association with outcomes. Univariate analysis was performed comparing children and adults. Multivariate analysis was used to determine factors associated with outcomes.

RESULTS

16,834 events occurred in 608 centers (16,245 adult, 537 pediatric). Adults had more frequent return of spontaneous circulation (53% vs 47%, p = 0.02), 24h survival (35% vs 30%, p = 0.02), and survival to discharge (23% vs 20%, p = NS) than children. Children were less frequently monitored (62% vs 82%) or witnessed (79% vs 88%), had longer duration (24 m vs 17 m), more epinephrine doses (3 vs 2), and more frequent intubation attempts (64% vs 55%) than adults. There were no differences in time to compressions, vasopressor administration, or defibrillation between children and adults. On multivariate analysis, age had no association with outcomes.

CONCLUSIONS

Survival following CPR in the ED is similar for adults and children. While univariate differences exist between children and adults, neither age nor specific processes of care are independently associated with outcomes.

Review of Simulation in Pediatrics: The Evolution of a Revolution

Recent changes in medical education have highlighted the importance of experiential learning. Simulation is one model that has gained significant attention in the last decade and has been widely adopted as a training and assessment tool in medical education. Pediatric simulation has been utilized to teach various skills including resuscitation and trauma management, procedural skills, and team training. It is also a valuable tool for health care educators, as it allows learners to achieve competence without putting patients at risk. Recent literature demonstrates increased retention of knowledge and skills after simulation-based training. Further research is required to improve current simulation curriculums, develop validated assessment tools, and to demonstrate improved clinical outcomes after simulation-based training. We conducted an online search of original and review articles related to simulation and pediatric medical education and provide an overview of the role and utility of simulation in pediatrics. Key PointsSimulation in pediatrics has been widely accepted and adapted as a training and assessment tool in medical education.Simulation in pediatrics has been utilized to teach various skills including resuscitation and trauma management, procedural skills, and team training.Further research is required to improve current simulation curriculums, to develop validated assessment tools, and to demonstrate improved clinical outcomes after simulation-based training.

In-hospital pediatric cardiac arrest in Honduras

OBJECTIVES

The objective of this study was to analyze the characteristic and the prognostic factors of in-hospital pediatric cardiac arrest (CA) in a public hospital Honduras.

METHODS

A prospective observational study was performed on pediatric in-hospital CA as a part of a multicenter international study. One hundred forty-six children were studied. The primary end point was survival at hospital discharge. Univariate and multivariate logistic regression analyses were performed to assess the influence of each factor on mortality.

RESULTS

Cardiac arrest occurred in the emergency department in 66.9%. Respiratory diseases and sepsis were predominant causes of CA. Return of spontaneous circulation was achieved in 60% of patients, and 22.6% survived to hospital discharge. The factors related with mortality were nonrespiratory cause of CA (odds ratio [OR], 2.55; P = 0.045), adrenaline administration (OR, 4.96; P = 0.008), and a duration of cardiopulmonary resuscitation more than 10 minutes (OR, 3.40; P = 0.012).

CONCLUSIONS

In-hospital CA in children in a developing country has low survival. Patients with nonrespiratory causes and those who need adrenaline administration and prolonged resuscitation had worse prognosis.

Post return of spontaneous circulation factors associated with mortality in pediatric in-hospital cardiac arrest: a prospective multicenter multinational observational study

INTRODUCTION

Most studies have analyzed pre-arrest and resuscitation factors associated with mortality after cardiac arrest (CA) in children, but many patients that reach return of spontaneous circulation die within the next days or weeks. The objective of our study was to analyze post-return of spontaneous circulation factors associated with in-hospital mortality after cardiac arrest in children.

METHODS

A prospective multicenter, multinational, observational study in 48 hospitals from 12 countries was performed. A total of 502 children aged between 1 month and 18 years with in-hospital cardiac arrest were analyzed. The primary endpoint was survival to hospital discharge. Univariate and multivariate logistic regression analyses were performed to assess the influence of each post-return of spontaneous circulation factor on mortality.

RESULTS

Return of spontaneous circulation was achieved in 69.5% of patients; 39.2% survived to hospital discharge and 88.9% of survivors had good neurological outcome. In the univariate analysis, post- return of spontaneous circulation factors related with mortality were pH, base deficit, lactic acid, bicarbonate, FiO2, need for inotropic support, inotropic index, dose of dopamine and dobutamine at 1 hour and at 24 hours after return of spontaneous circulation as well as Pediatric Intensive Care Unit and total hospital length of stay. In the multivariate analysis factors associated with mortality at 1 hour after return of spontaneous circulation were PaCO2 < 30 mmHg and >50 mmHg, inotropic index >14 and lactic acid >5 mmol/L. Factors associated with mortality at 24 hours after return of spontaneous circulation were PaCO2 > 50 mmHg, inotropic index >14 and FiO2 ≥ 0.80.

CONCLUSIONS

Secondary in-hospital mortality among the initial survivors of CA is high. Hypoventilation, hyperventilation, FiO2 ≥ 0.80, the need for high doses of inotropic support, and high levels of lactic acid were the most important post-return of spontaneous circulation factors associated with in-hospital mortality in children in our population.

Outcomes associated with amiodarone and lidocaine in the treatment of in-hospital pediatric cardiac arrest with pulseless ventricular tachycardia or ventricular fibrillation

AIM

To determine the association between amiodarone and lidocaine and outcomes in children with cardiac arrest with pulseless ventricular tachycardia (pVT) and ventricular fibrillation (VF).

BACKGROUND

Current AHA guidelines for CPR and emergency cardiovascular care recommend amiodarone for cardiac arrest in children associated with shock refractory pVT/VF, based on a single pediatric study and extrapolation from adult data.

METHODS

Retrospective cohort study from the Get With the Guidelines-Resuscitation database for in-patient cardiac arrest. Patients<18 years old with pVT/VF cardiac arrest were included. Patients receiving amiodarone or lidocaine prior to arrest or whose initial arrest rhythm was unknown were excluded. Univariate analysis was performed to assess the association between patient and event factors and clinical outcomes. Multivariate analysis was performed to address independent association between lidocaine and amiodarone use and outcomes.

RESULTS

Of 889 patients, 171 (19%) received amiodarone, 295 (33%) received lidocaine, and 82 (10%) received both. Return of spontaneous circulation (ROSC) occurred in 484/889 (54%), 24-h survival in 342/874 (39%), and survival to hospital discharge in 194/889 (22%). Lidocaine was associated with improved ROSC (adjusted OR 2.02, 95% CI 1.36-3), and 24-h survival (adjusted OR 1.66, 95% CI 1.11-2.49), but not hospital discharge. Amiodarone use was not associated with ROSC, 24h survival, or survival to discharge.

CONCLUSIONS

For children with in-hospital pVT/VF, lidocaine use was independently associated with improved ROSC and 24-h survival. Amiodarone use was not associated with superior rates of ROSC, survival at 24h. Neither drug was associated with survival to hospital discharge.

In-hospital pediatric cardiac arrest in Spain

INTRODUCTION AND OBJECTIVES

The objective was to analyze the characteristics and prognostic factors of in-hospital pediatric cardiac arrest in Spain.

METHODS

A prospective observational study was performed to examine in-hospital pediatric cardiac arrest. Two hundred children were studied, aged between 1 month and 18 years, with in-hospital cardiac arrest. Univariate and multivariate logistic regression analyses were performed to assess the influence of each factor on survival to hospital discharge.

RESULTS

Return of spontaneous circulation was achieved in 74% of the patients and 41% survived to hospital discharge. The survival rate was significantly higher than that reported in a previous Spanish study 10 years earlier (25.9%). In the univariate analysis, the factors related to mortality were body weight higher than 10 kg; continuous infusion of vasoactive drugs prior to cardiac arrest; sepsis and neurological disorders as causes of cardiac arrest, the need for treatment with adrenaline, bicarbonate, and volume expansion, and prolonged cardiopulmonary resuscitation. In the multivariate analysis, the factors related to mortality were hematologic/oncologic diseases, continuous infusion of vasoactive drugs prior to cardiac arrest, cardiopulmonary resuscitation for more than 20 min, and treatment with bicarbonate and volume expansion.

CONCLUSIONS

Survival after in-hospital cardiac arrest in children has significantly improved in recent years. The factors related to in-hospital mortality were hematologic/oncologic diseases, continuous infusion of vasoactive drugs prior to cardiac arrest, the duration of cardiopulmonary resuscitation, and treatment with bicarbonate and volume expansion.

Ratio of PICU versus ward cardiopulmonary resuscitation events is increasing

OBJECTIVES

The aim of this study was to evaluate the relative frequency of pediatric in-hospital cardiopulmonary resuscitation events occurring in ICUs compared to general wards. We hypothesized that the proportion of pediatric cardiopulmonary resuscitation provided in ICUs versus general wards has increased over the past decade, and this shift is associated with improved resuscitation outcomes.

DESIGN

Prospective and observational study.

SETTING

Total of 315 hospitals in the American Heart Association's Get With The Guidelines-Resuscitation database.

PATIENTS

Total of 5,870 pediatric cardiopulmonary resuscitation events between January 1, 2000 and September 14, 2010. Cardiopulmonary resuscitation events were defined as external chest compressions longer than 1 minute.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was proportion of total ICU versus general ward cardiopulmonary resuscitation events over time evaluated by chi-square test for trend. Secondary outcome included return of spontaneous circulation following the cardiopulmonary resuscitation event. Among 5,870 pediatric cardiopulmonary resuscitation events, 5,477 (93.3%) occurred in ICUs compared to 393 (6.7%) in inpatient wards. Over time, significantly more of these cardiopulmonary resuscitation events occurred in the ICU compared to the wards (test for trend: p<0.01), with a prominent shift noted between 2003 and 2004 (2000-2003: 87-91% vs 2004-2010: 94-96%). In a multivariable model controlling for within center variability and other potential confounders, return of spontaneous circulation increased in 2004-2010 compared with 2000-2003 (relative risk, 1.08; 95% CI, 1.03-1.13).

CONCLUSIONS

In-hospital pediatric cardiopulmonary resuscitation is much more commonly provided in ICUs than in wards, and the proportion has increased significantly over the past decade, with concomitant increases in return of spontaneous circulation.

Simplified dispatcher instructions improve bystander chest compression quality during simulated pediatric resuscitation

AIM

Cardiopulmonary resuscitation (CPR) quality is associated with survival outcomes after out-of-hospital cardiac arrest. The objective of this study was to evaluate the effectiveness of simplified dispatcher CPR instructions to improve the chest compression (CC) quality during simulated pediatric cardiac arrest in public places.

METHODS

Adult bystanders recruited in public places were randomized to receive one of two scripted dispatcher CPR instructions: (1) "Push as hard as you can" (PUSH HARD) or (2) "Push approximately 2 inches" (TWO INCHES). A pediatric manikin with realistic CC characteristics (similar to a 6-year-old child), and a CPR recording defibrillator was used for quantitative CC data collection during a 2-min simulated pediatric scenario. The primary outcome was average CC depth treated as a continuous variable. Secondary outcomes included compliance with American Heart Association (AHA) CPR targets. Analysis was by two-sided unpaired t-test and Chi-square test, as appropriate.

RESULTS

128 out of 140 providers screened met inclusion/exclusion criteria and all 128 consented. The average CC depth (mean (SEM)) was greater in PUSH HARD compared to TWO INCHES (43 (1) vs. 36 (1) mm, p<0.01) and met AHA targets more often (39% (25/64) vs. 20% (13/64), p=0.02). CC rates trended higher in the PUSH HARD group (93 (4) vs. 82 (4) CC/min, p=0.06). More providers did not achieve full chest recoil with PUSH HARD compared to TWO INCHES (53% (34/64) vs. 75% (48/64), p=0.01).

CONCLUSIONS

Simplified dispatcher assisted pediatric CPR instructions: "Push as hard as you can" was associated with lay bystanders providing deeper and faster CCs on a simulated, 6-year-old pediatric manikin. However, percentage of providers leaning between CC increased. The potential effect of these simplified instructions in younger children remains unanswered.

Advances in recognition, resuscitation, and stabilization of the critically ill child

Advances in early recognition, effective response, and high-quality resuscitation before, during, and after cardiac arrest have resulted in improved survival for infants and children over the past 10 years. This review addresses several key factors that can make a difference in survival outcomes, including the etiology of pediatric cardiac arrests in and out of hospital, mechanisms and techniques of circulation of blood flow during cardiopulmonary resuscitation (CPR), quality of CPR, meticulous postresuscitative care, and effective training. Monitoring and quality improvement of each element in the system of resuscitation care are increasingly recognized as key factors in saving lives.

Pediatric cardiopulmonary arrest in the postanesthesia care unit: analysis of data from the American Heart Association Get With The Guidelines-Resuscitation registry

BACKGROUND

Nearly 20% of anesthesia-related pediatric cardiopulmonary arrests (CPAs) occur during emergence or recovery. The aims of this study were to describe (i) the nature of pediatric postanesthesia care unit (PACU) CPA and subsequent outcomes and (ii) factors associated with mortality.

METHODS

Cardiopulmonary Arrests occurring in PACU in children (<18 years) were identified from the American Heart Association Get With The Guidelines-Resuscitation, multicenter CPA registry. Demographics, underlying conditions, cause(s) of CPA, monitoring, interventions and outcomes were extracted. Descriptive statistics were used to characterize data, and odds ratios (OR) with confidence intervals (CI) were calculated as appropriate to compare survivors and nonsurvivors.

RESULTS

Twenty seven CPA events were included: 67% in children <5 years and 30% in infants (<1 year). Most children (78%) had underlying comorbidities, including 15% with congenital heart disease. Respiratory issues were the most frequent causes of CPA (44%), but cardiac/hemodynamic causes were associated with nonsurvival (P = 0.01). Nonsurvival was also associated with older age (P = 0.02), weekend occurrence (P < 0.01), nonpediatric setting (P = 0.02) and occurrence at night (P = 0.04).

CONCLUSIONS

This study identified similar risk factors and underlying causes as described in previous reports of pediatric perioperative CPA, with higher mortality following a cardiac/hemodynamic cause.

Cardiopulmonary resuscitation in hospitalized children with cardiovascular disease: estimated prevalence and outcomes from the kids' inpatient database

OBJECTIVE

Hospitalized children with cardiovascular disease may be at increased risk of cardiac arrest; however, little data exist regarding prevalence, risk factors, or outcomes of cardiopulmonary resuscitation in these patients. We sought to characterize national estimates of cardiopulmonary resuscitation and death after cardiopulmonary resuscitation for hospitalized children with cardiovascular disease.

SETTING

A total of 3,739 hospitals in 38 states participating in Kids' Inpatient Database.

DESIGN

Retrospective analysis of the 2000, 2003, and 2006 Healthcare Cost and Utilization Project Kids' Inpatient Database was performed. Sample weighting was employed to produce national estimates.

MEASUREMENTS AND MAIN RESULTS

Cardiovascular disease was identified in 2.2% of the estimated 22,175,468 (95% confidence interval 21,391,343-22,959,592) hospitalizations. Cardiopulmonary resuscitation occurred in 0.74% (3,698; 95% confidence interval 3,205-4,191) of hospitalizations of children with cardiovascular disease, compared with 0.05% (11,726; 95% confidence interval 10,647-12,805) without cardiovascular disease (odds ratio 13.8, 95% confidence interval 12.8-15.0). The highest frequency of cardiopulmonary resuscitation occurred with myocarditis (3.0% of admissions), heart failure (2.0%), and coronary pathology (2.0%). Compared with other forms of cardiovascular disease identified in this study, single-ventricle patients were the only subgroup who exhibited a higher mortality after cardiopulmonary resuscitation (mortality 65% vs. 55%; odds ratio 1.7 [95% confidence interval 1.2-2.6]), while those who had undergone cardiac surgery exhibited a lower mortality rate (mortality 48% vs. 57%; odds ratio 0.6 [95% confidence interval 0.5-0.8]).

CONCLUSIONS

Cardiopulmonary resuscitation occurs in approximately 7 per 1,000 hospitalizations of children with cardiovascular disease, a rate greater than ten-fold that observed in hospitalizations of children without cardiovascular disease. Single-ventricle patients demonstrated increased mortality after cardiopulmonary resuscitation, while recent cardiac surgery was associated with a reduced odds of death after cardiopulmonary resuscitation. Further studies are needed to confirm these findings and develop techniques to prevent cardiac arrest in this high-risk population.

Characteristics and outcomes of pediatric out-of-hospital cardiac arrest by scholastic age category

OBJECTIVES

There is a paucity of data examining nationwide population-based incidences and outcomes of pediatric out-of-hospital cardiac arrest. The objective of this study is to describe the detailed characteristics of pediatric out-of-hospital cardiac arrest by scholastic age category and to evaluate the impact of bystander cardiopulmonary resuscitation and public access-automated external defibrillators on the 1-month survival and favorable neurological status of pediatric out-of-hospital cardiac arrest patients.

DESIGN

A nationwide, population-based, observational study.

SETTING

Nationwide emergency medical system in Japan.

PATIENTS

Out-of-hospital cardiac arrest patients aged ≤ 18 yr.

MEASUREMENTS AND MAIN RESULTS

We identified 7,624 pediatric out-of-hospital cardiac arrest patients (≤ 18 yr old) from a nationwide population-based out-of-hospital cardiac arrest database in Japan from 2005 to 2008 and stratified them into five categories by scholastic age. The overall rates of 1-month survival and favorable neurological outcomes were 11.0% and 5.1%, respectively. Bystander cardiopulmonary resuscitation resulted in a significant improvement in both 1-month survival (odds ratio 2.81; 95% confidence interval 2.30-3.44) and favorable neurological outcomes (odds ratio 4.55; 95% confidence interval 3.35-6.18). Performing public access-automated external defibrillators had a significant effect on the 1-month survival rate (odds ratio 3.51; 95% confidence interval 1.81-6.81) and favorable neurological outcomes (odds ratio 5.13; 95% confidence interval 2.64-9.96).

CONCLUSIONS

This study demonstrated that bystander cardiopulmonary resuscitation and public access-automated external defibrillators had a significant impact on the outcomes of pediatric out-of-hospital cardiac arrest. The improved survival associated with bystander cardiopulmonary resuscitation and public access-automated external defibrillators are clinically important and are of major public health importance for school-aged out-of-hospital cardiac arrest patients.

Personnel and unit factors impacting outcome after cardiac arrest in a dedicated pediatric cardiac intensive care unit

OBJECTIVE

To assess the impact of personnel and unit factors on outcome from cardiac arrest in a dedicated pediatric cardiac intensive care unit.

DESIGN

Retrospective medical record review.

SETTING

Dedicated cardiac intensive care unit at a quaternary academic children's hospital.

PATIENTS

Children and young adults who had cardiac arrest while cared for in the pediatric cardiac intensive care unit from January 1, 2006, to December 31, 2008.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

One hundred two index cardiac arrests over a 3-yr period in our pediatric cardiac intensive care unit were reviewed. We defined successful resuscitation as either return of spontaneous circulation or successful cannulation to extracorporeal membrane oxygenation. Differences in resuscitation rates were assessed across categorical systems variables using logistic regression. The rate of successful resuscitation was 84% (return of spontaneous circulation 74%, extracorporeal membrane oxygenation 10%). Survival to hospital discharge was 48% for patients who had a cardiac arrest. 11% of arrests during the week and 31% during weekends (odds ratio 3.8; 95% confidence interval 1.2-11.5) were not successfully resuscitated. Unsuccessful resuscitation was significantly more likely when the primary nurse had <1 yr of experience in the pediatric cardiac intensive care unit (50% <1 yr vs. 13% >1 yr; odds ratio 6.8; confidence interval 1.5-31.0). Cardiac arrest on a weekend day and <1-yr pediatric cardiac intensive care unit nursing experience were also associated with unsuccessful resuscitation in a multivariable model. Resuscitation outcomes were similar when senior intensive care unit attending physicians were on-call at the time of arrest compared with other intensive care unit staff (17% unsuccessful vs. 15%; odds ratio 1.2; confidence interval 0.4-3.7). Arrests where the attending physician was present at the onset resulted in unsuccessful resuscitation 18% of the time vs. 14% for events where the attending was not present (odds ratio 1.3; confidence interval 0.5-3.9).

CONCLUSIONS

Our data suggest that personnel and unit factors may impact outcome after cardiac arrest in a pediatric cardiac intensive care unit. Weekend arrests and less experience of the primary nurse were risk factors for unsuccessful resuscitation. Neither presence at arrest onset nor experience of the attending cardiac intensivist was associated with outcome.

The association between hospital type and mortality among critically ill children in US EDs

STUDY AIM

Little is known about the setting of care for critically ill children and whether differences in outcomes are related to the presenting hospital type. This study describes the characteristics of hospitals to which critically ill children present and explores the associations between hospital factors and mortality.

METHODS

This is a retrospective cohort study using data from the 2007 Healthcare Cost and Utilization Project National Emergency Department Sample, representative of all US ED visits. Subjects include children aged 0-18 with ICD9 codes for cardiac arrest, respiratory arrest and/or respiratory failure. Predictor variables include: age, sex, presence of chronic illness, self-pay, public insurance, trauma diagnosis, major trauma center, urban hospital, ED volume and teaching hospital. Multivariate logistic regression estimates predictors of mortality. Analyses integrate clusters, strata, and weights from the probability sample.

RESULTS

There were an estimated 29 million pediatric ED visits in 2007 including 42,036 (0.1%) visits for cardiac or respiratory failure. Teaching hospitals (OR 0.57, 95% CI 0.50-0.66), trauma centers (OR 0.76, 95% CI 0.67-0.86), and urban hospitals (OR 0.78, 95% CI 0.63-0.97) were associated with lower mortality odds. Presence of a chronic illness (OR 14.5, 95% CI 10.5-20.1), diagnosis of an injury (OR 1.2, 95% CI 1.1-1.4) and self-pay status (OR 3.6, 95% CI 2.9-4.4) were associated with increased mortality odds.

CONCLUSIONS

The majority of children with cardiac and respiratory arrest present to urban teaching hospitals and trauma centers. After accounting for important confounders, mortality is lower at teaching hospitals and/or major trauma centers.

Nurse reports on resource adequacy in hospitals that care for acutely ill children

Despite the estimated 1.8 million children admitted to hospitals annually, little is known about the quality of care and the adequacy of resources in hospitals that care for acutely ill infants and children. Using survey data from 3,819 pediatric nurses working in 498 hospitals, we found that nursing resources vary significantly across different types of hospitals that care for children. Nurses working in a children's hospital within a hospital, and on a pediatric unit in a general hospital were more likely than nurses in freestanding children's hospitals to report inadequate nursing resources. We also found that inadequate nursing resources were associated with surveillance left undone and missed changes in patients' condition. These findings have implications for the quality and safety of pediatric care.

Pediatric sudden cardiac arrest

Pediatric sudden cardiac arrest (SCA), which can cause sudden cardiac death if not treated within minutes, has a profound effect on everyone: children, parents, family members, communities, and health care providers. Preventing the tragedy of pediatric SCA, defined as the abrupt and unexpected loss of heart function, remains a concern to all. The goal of this statement is to increase the knowledge of pediatricians (including primary care providers and specialists) of the incidence of pediatric SCA, the spectrum of causes of pediatric SCA, disease-specific presentations, the role of patient and family screening, the rapidly evolving role of genetic testing, and finally, important aspects of secondary SCA prevention. This statement is not intended to address sudden infant death syndrome or sudden unexplained death syndrome, nor will specific treatment of individual cardiac conditions be discussed. This statement has been endorsed by the American College of Cardiology, the American Heart Association, and the Heart Rhythm Society.
