RESUMO
BACKGROUND: An alternative surgical approach for hypoplastic left heart syndrome is the Hybrid pathway, which delays the risk of acute kidney injury outside of the newborn period. We sought to determine the incidence, and associated morbidity, of acute kidney injury after the comprehensive stage 2 and the cumulative incidence after the first two operations in the Hybrid pathway. DESIGN: A single centre, retrospective study was conducted of hypoplastic left heart patients completing the second-stage palliation in the Hybrid pathway from 2009 to 2018. Acute kidney injury was defined utilising Kidney Diseases Improving Global Outcomes criteria. Perioperative and post-operative characteristics were analysed. RESULTS: Sixty-one patients were included in the study cohort. The incidence of acute kidney injury was 63.9%, with 36.1% developing severe injury. Cumulatively after the Hybrid Stage 1 and comprehensive stage 2 procedures, 69% developed acute kidney injury with 36% developing severe injury. The presence of post-operative acute kidney injury was not associated with an increase in 30-day mortality (acute kidney injury 7.7% versus none 9.1%; p = > 0.9). There was a significantly longer median duration of intubation among those with acute kidney injury (acute kidney injury 32 (8, 155) hours vs. no injury 9 (0, 94) hours; p = 0.018). CONCLUSIONS: Acute kidney injury after the comprehensive stage two procedure is common and accounts for most of the kidney injury in the first two operations of the Hybrid pathway. No difference in mortality was detected between those with acute kidney injury and those without, although there may be an increase in morbidity.

BACKGROUND: The US Pediatric Heart Allocation Policy (PHAP) was revised in March 2016, with the goal of reducing waitlist mortality. We evaluated the hypothesis that these changes, which increased status exceptions, have worsened racial disparities in waitlist outcomes. METHODS: Children in the Pediatric Heart Transplant Study database listed for first heart transplant from January 2012 - June 2020 were included and stratified by listing before (Era 1) or after (Era 2) the PHAP revision. RESULTS: A total of 4,089 children were listed during the study period. Compared with white children (n = 2648), non-white children (n = 1441) were more likely to have an underlying diagnosis of cardiomyopathy in both eras. Waitlist mortality was similar in white and non-white children in Era 1, but comparatively worse for non-white children in Era 2. In multivariable analysis controlling for diagnosis, age, and severity markers, non-white children had a significantly higher waitlist mortality only in Era 2 (Era 1: sHR 1.22 [95%CI 0.90 - 1.66] vs. Era 2: sHR 1.57 [95%CI 1.17 - 2.10]). CONCLUSIONS: Widening racial disparities in waitlist mortality may be an unintended consequence of the 2016 PHAP revision. Additional analyses may inform the degree to which this policy vs. unrelated changes in care differentially contribute to these disparities.

The use of mechanical circulatory support (MCS) for pediatric patients who have undergone heart transplant has grown rapidly in the past decade. This includes support in the immediate post-transplant period and "rescue" therapy for patient later in their transplant course. Extracorporeal membrane oxygenation (ECMO) remains a standard modality of support for intraoperative concerns and for acute decompensation in the immediate post-transplant period. However, both pulsatile and continuous flow ventricular assist devices (VADs) have been used with increasing success in transplant patients for longer durations of support. Centers participating in the Pediatric Heart Transplant Society (PHTS) were queried to provide their internal protocols and rationale for mechanical circulatory support following heart transplant. These protocols coupled with evidence-based literature were used to provide the following description of clinical approaches to MCS in the transplant patient highlighting areas of both broad consensus and significant practice variation.

Treatment of infants with hypoplastic left heart syndrome (HLHS) remains challenging, and those affected remain with significant risks for mortality and morbidity throughout their lifetimes. The maternal-fetal environment (MFE) has been shown to affect outcomes for infants with HLHS after the Norwood procedure. The hybrid procedure, comprised of both catheterization and surgical components, is a less invasive option for initial intervention compared to the Norwood procedure. It is unknown how the MFE impacts outcomes following the hybrid procedure. This is a single-center, retrospective study of infants born with HLHS who underwent hybrid palliation from January 2009 to August 2021. Predictor variables analyzed included fetal, maternal, and postnatal factors. The primary outcome was mortality prior to Stage II palliation. We studied a 144-subject cohort. There was a statistically significant difference in mortality prior to stage II palliation in infants with prematurity, small for gestational age, and aortic atresia subtype (p < 0.001, p = 0.009, and p = 0.008, respectively). There was no difference in mortality associated with maternal diabetes, hypertension, obesity, smoking or illicit drug use, or advanced maternal age. State and national area deprivation index scores were associated with increased risk of mortality in the entire cohort, such that infants born in areas with higher deprivation had a higher incidence of mortality. Several markers of an impaired MFE, including prematurity, small for gestational age, and higher deprivation index scores, are associated with mortality following hybrid palliation. Individual maternal comorbidities were not associated with higher mortality. The MFE may be a target for prenatal counseling and future interventions to improve pregnancy and neonatal outcomes in this population.
RESUMO
OBJECTIVE: Acute kidney injury leads to worse outcomes following paediatric cardiac surgery. There is a lack of literature focusing on acute kidney injury after the Hybrid stage 1 palliation for single ventricle physiology. Patients undergoing the Hybrid Stage 1, as a primary option, may have a lower incidence of kidney injury than previously reported. When present, kidney injury may increase the risk of post-operative morbidity and mortality. METHODS: A retrospective, single centre review was conducted in patients with hypoplastic left heart syndrome who underwent Hybrid Stage 1 from 2008 to 2018. Acute kidney injury was defined as a dichotomous yes (meeting any injury criteria) or no (no injury) utilising two different criteria utilised in paediatrics. The impact of kidney injury on perioperative characteristics and 30-day mortality was analysed. RESULTS: The incidence of acute kidney injury is 13.4-20.7%, with a severe injury rate of 2.4%. Patients without a prenatal diagnosis of hypoplastic left heart syndrome have a higher incidence of kidney injury than those prenatally diagnosed, (40% versus 14.5%, p = 0.024). Patients with acute kidney injury have a significantly higher incidence of 30-day mortality, 27.3%, compared to without, 5.6% (p = 0.047). DISCUSSION: The incidence of severe acute kidney injury after the Hybrid Stage 1 palliation is low. A prenatal diagnosis may be associated with a lower incidence of kidney injury following the Hybrid Stage 1. Though uncommon, severe acute kidney injury following Hybrid Stage 1 may be associated with higher 30-day mortality.

Hepatic fibrosis is a significant complication in adult Fontan patients suggesting development as a function of time since the surgery. Children with Fontan circulation are not routinely assessed for development of liver disease. We aimed to evaluate the effectiveness of serologic biomarkers and acoustic radiation force impulse (ARFI) elastography to detect liver disease in pediatric Fontan patients. Patients ≥ 1 year after Fontan operation prospectively had hepatic US with acoustic radiation force impulse and laboratory testing. Clinical cardiac data (echocardiograms, cardiac catheterizations) were reviewed. Statistical analysis was performed using Pearson's correlation coefficient, Wilcoxon rank-sum test and Kruskal-Wallis test. Forty patients were enrolled with median age of 11 years and median time since Fontan of 6.5 years. Platelet count negatively correlated with years since Fontan (p < 0.000). Thrombocytopenia was noted in 15% of patients with the lowest platelet count of 78 K/cu mm, in a patient >10 years from the Fontan (DORV) operation. Alanine transaminase (ALT, p = 0.034) and aspartate aminotransferase (AST, p = 0.009) were higher in patients with Extracardiac Conduit Fontan and not in other Fontan operations. Heterogeneous echotexture on liver ultrasound correlated with years since Fontan (p = 0.022), however all acoustic radiation force impulse values were elevated (> 1.34 m/s) and did not correlate with age, years since Fontan, labs or imaging. FibroSure values did not correlate with years since Fontan. This suggests that ARFI may be elevated due to passive hepatic congestion, limiting its value in this patient population. Additional testing is necessary to identify reliable noninvasive screening modalities for hepatic fibrosis in Fontan patients. Our study is the largest pediatric study to evaluate ARFI in patients after the Fontan operation and showed increased shear wave speed for all patients with no correlation with time since palliation. Decreasing platelet count may indicate the development of liver fibrosis.
RESUMO
Pediatric patients awaiting heart transplant face high mortality rates due to donor organ shortages, including non-use of marginal donor hearts. We examined national trends in pediatric marginal donor heart use over time. UNOS data were queried for heart donors <18 years from 2005 to 2014. The proportion of donor hearts considered marginal was determined using previously cited marginal characteristics: left ventricular ejection fraction (LVEF) <50%, use of ≥2 inotropes, cerebrovascular death, CDC high-risk status, and eGFR < 30 mL/min/1.73 m2 . Disposition of donor hearts was determined and stratified by marginal donor status. Of 6778 pediatric hearts offered from 2005 to 2014, 2373 (35.0%) were considered marginal. Non-use of marginal donor hearts was significantly higher than that of donor hearts without any marginal characteristics (59.5% vs 20.3%, P < .001). In particular, LVEF < 50% and donor inotropes were associated with high rates of organ non-use among pediatric donors. Yet, non-use of marginal donor organs decreased from 67% to 48% from 2005 to 2014 (P < .001). Although the proportion of pediatric donor hearts used for pediatric patients has increased, more than half of donor hearts are declined for use in pediatric recipients due, in part, to perceived marginal status.

BACKGROUND: Music therapy (MT) can relieve distressing end-of-life symptoms, but little is known regarding its effect on caregivers who are at risk for emotional distress as their loved ones approach death. MEASURES: Quality of life (Linear Analogue Self-Assessment), depressive and anxiety symptoms (Patient Health Questionnaire for Depression and Anxiety), and stress (Role Overload Measure) pre-MT, post-MT and at 6-month follow-up, as well as a satisfaction survey post-MT. INTERVENTION: Single MT session for 20-45 minutes OUTCOMES: 15/20 completed MT intervention, 14 also completed pre-MT and post-MT assessments, and 9 completed assessments at all 3 timepoints. Post-MT satisfaction survey (n=14) showed 100% of caregivers were very satisfied with MT and would recommend to others, and found MT very effective for emotional support (85.7%), stress relief (78.6%), spiritual support (71.4%), general feeling of wellness (71.4%), relaxation (69.2%), and pain relief (33.3%). CONCLUSIONS: Research on MT is feasible for caregivers of inpatient hospice patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03322228.

Children with congenital heart disease who undergo cardiac surgery are vulnerable to acute kidney injury (AKI). This study sought to evaluate the role of angiotensin-converting enzyme (ACE) inhibitors and other nephrotoxic medications in the risk for the development of AKI in neonates and children undergoing cardiac surgery. A retrospective review of all patients younger than 2 years admitted to the cardiac intensive care unit after cardiac surgery from March 2007 to September 2008 was conducted. Patients were included in the review if they received furosemide alone or in combination with an ACE inhibitor. Creatinine clearance was calculated, and the patient's maximal degree of AKI was classified by pRIFLE. A P value less than 0.05 was considered significant. Of the 319 patients who met the inclusion criteria, 149 (47%) received furosemide therapy alone and 170 (53%) received a combination of furosemide and an ACE inhibitor. Patients in the furosemide-only group (age, 5 months) were older than the patients who received both furosemide and an ACE inhibitor (age, 3.8 months; P = 0.024). Despite statistically higher Aristotle scores in the ACE-inhibitor group, the intraoperative variables did not differ between the two groups. Postoperatively, the ACE-inhibitor group had a decreased creatinine clearance (55.3 ml/min/1.73 m(2)) compared with the furosemide group (64.4 ml/min/1.73 m(2); P = 0.015) and an increased incidence of a pRIFLE maximal score of "F" (odds ratio [OR], 1.75; P = 0.033). However, after adjustment for additional risk factors, no difference in the occurrence of AKI resulted (OR, 0.939; P = 0.85) when patients received an ACE inhibitor. More than half of the study population received ACE inhibitors, but this treatment was not associated with an increase in AKI.

Pulmonary arterial hypertension (PAH) is a complex disease involving increased resistance in the pulmonary arteries and subsequent right ventricular (RV) remodeling. Ventricular-arterial interactions are fundamental to PAH pathophysiology but are rarely captured in computational models. It is important to identify metrics that capture and quantify these interactions to inform our understanding of this disease as well as potentially facilitate patient stratification. Towards this end, we developed and calibrated two multi-scale high-resolution closed-loop computational models using open-source software: a high-resolution arterial model implemented using CRIMSON, and a high-resolution ventricular model implemented using FEniCS. Models were constructed with clinical data including non-invasive imaging and invasive hemodynamic measurements from a cohort of pediatric PAH patients. A contribution of this work is the discussion of inconsistencies in anatomical and hemodynamic data routinely acquired in PAH patients. We proposed and implemented strategies to mitigate these inconsistencies, and subsequently use this data to inform and calibrate computational models of the ventricles and large arteries. Computational models based on adjusted clinical data were calibrated until the simulated results for the high-resolution arterial models matched within 10% of adjusted data consisting of pressure and flow, whereas the high-resolution ventricular models were calibrated until simulation results matched adjusted data of volume and pressure waveforms within 10%. A statistical analysis was performed to correlate numerous data-derived and model-derived metrics with clinically assessed disease severity. Several model-derived metrics were strongly correlated with clinically assessed disease severity, suggesting that computational models may aid in assessing PAH severity.
RESUMO
We sought to analyze the outcome of hemodynamically significant acute graft rejection in pediatric heart transplant recipients from a single-center experience. Acute graft rejection remains a major cause of morbidity and mortality for patients who undergo orthotopic heart transplantation and has been associated with the severity of the rejection episode. A retrospective review of all children experiencing a hemodynamically significant rejection episode after orthotopic heart transplantation was performed. Fifty-three patients with 54 grafts had 70 rejection episodes requiring intravenous inotropic support. Forty-one percent of these patients required high-dose inotropic support, with the remaining 59% of patients requiring less inotropic support. Overall graft survival to hospital discharge was 41% for patients in the high-dose group compared to 94% in the low-dose group. Six-month graft survival in patients who required high-dose inotropes remained at 41% compared to 44% in the low-dose group. Hemodynamically significant acute graft rejection in pediatric heart transplant recipients is a devastating problem with poor short- and long-term outcomes. Survival to hospital discharge is dismal in patients who require high-dose inotropic support. In contrast, survival to discharge is quite good in patients who require only low-dose inotropic support; however, six-month graft survival in this group is low secondary to a high incidence of graft failure related to worsening or aggressive transplant coronary artery disease.

BACKGROUND: Tricuspid valve (TV) and right ventricular (RV) function are major determinants of morbidity and mortality in patients with hypoplastic left heart syndrome (HLHS). We sought to retrospectively evaluate these parameters throughout the hybrid palliation strategy. METHODS: From 2002 to 2018, 203 patients with HLHS and variants presented for hybrid stage I (HS1). Echocardiographic evaluation of tricuspid regurgitation (TR) and RV function was assessed at multiple time points. Clinical outcomes including tricuspid valvuloplasty, transplantation, and death were reviewed. RESULTS: The most prevalent HLHS subtype was aortic atresia/mitral atresia. The presence of significant TR and/or RV dysfunction was 14.78% and 9.36%, respectively, at the time of initial HS1. There were 185 survivors following HS1 (91.13%, n = 185/203), while 147 patients underwent comprehensive stage II or bidirectional Glenn shunt (72.41%, n = 147/203). Tricuspid valvuloplasty was undertaken in nine patients (4.86%, n = 9/185). Ultimately, 100 patients underwent the Fontan procedure. The odds of development of significant TR and/or RV dysfunction were not statistically different throughout the stages of palliation (TR: odds ratio [OR] = 0.14-0.25, P = .5260; RV dysfunction: OR = 0.02-0.13, P = .3992). However, the risk of death and/or transplant was 2.5- to 3.8-fold when either were present alone or in combination (TR: OR = 2.58, P = .0356; RV dysfunction: OR = 3.84, P = .0262). Transplant-free survival at 15 years was 44.8%. CONCLUSION: Following hybrid palliation for HLHS, the majority of survivors have normal RV and TV functions. Tricuspid valvuloplasty was required in few patients. Once significant TR and/or RV dysfunction ensues, there is a two- to three-fold risk of death and/or transplant.

BACKGROUND: The Berlin Heart EXCOR Pediatric (EXCOR) ventricular assist device (VAD) was introduced in North America nearly 2 decades ago. The EXCOR was approved under Humanitarian Device Exemption status in 2011 and received post-market approval (PMA) in 2017 from Food and Drug Administration. Since the initial approval, the field of pediatric mechanical circulatory support has changed, specifically with regard to available devices, anticoagulation strategies, and the types of patients supported. This report summarizes the outcomes of patients supported with EXCOR from the Advanced Cardiac Therapies Improving Outcomes Network (ACTION) registry. These data were part of the PMA surveillance study (PSS) required by the Food and Drug Administration. METHODS: ACTION is a learning collaborative of over 40 pediatric heart failure programs worldwide, which collects data for all VAD implantations as one of its initiatives. All patients in North America with EXCOR implants reported to ACTION from 2018 to 2020 (nâ¯=â¯72) who had met an outcome were included in the EXCOR PSS group. This was compared with a historical, previously reported Berlin Heart EXCOR study group (Berlin Heart study [BHS] group, nâ¯=â¯320, 2007â2014). RESULTS: Patients in the PSS group were younger, were smaller in weight/body surface area, were more likely to have congenital heart disease, and were less likely to receive a bi-VAD than those in the BHS group. Patients in the PSS group were less likely to be in Interagency Registry for Mechanically Assisted Circulatory Support Profile 1 and were supported for a longer duration. The primary anticoagulation therapy for 92% of patients in the PSS group was bivalirudin. Success, defined as being transplanted, being weaned for recovery, or being alive on a device at 180 days after implantation, was 86% in the PSS group compared with 76% in the BHS group. Incidence of stroke was reduced by 44% and the frequency of pump exchange by 40% in the PSS group compared with those in the BHS group. Similarly, all other adverse events, including major bleeding, were reduced in the PSS group. CONCLUSIONS: The PSS data, collected through ACTION, highlight the improvement in outcomes for patients supported with EXCOR compared with the outcomes in a historical cohort. These findings may be the result of changes in patient care practices over time and collaborative learning.

Decreasing practice variation and following evidence-based clinical guidelines improve patient outcomes and often reduce cost. Essentially all postsurgical cardiac patients require diuretics. The approach to diuresis in the pediatric cardiothoracic intensive care unit (CTICU) is not standardized. Our objective was to develop and implement guidelines for diuretic utilization in the CTICU to reduce high charge medication utilization while maintaining the delivery of high-quality care. METHODS: Two of the top 10 medications by charge in the CTICU during 2016 were diuretics [fenoldopam and intravenous (IV) chlorothiazide]. Standardized diuretic utilization guidelines were developed to reduce the utilization of fenoldopam and IV chlorothiazide. We implemented guidelines in April 2017. The utilization of fenoldopam and IV chlorothiazide, as well as overall diuretic charges, before and after guideline implementation were compared. RESULTS: We normalized all comparisons to 100 CTICU patient-days. Fenoldopam starts were reduced from 1.1 in 2016 to 0.03 in 2019 (through February); days of fenoldopam use were reduced from 4 in 2016 to 0.15 days in 2019 (through February); IV chlorothiazide doses decreased from 20 in 2016 to 8 in 2019 (through February). These changes reduced the mean charges for diuretics from $25,762 in 2016 to $8,855 in 2019 (through February). CTICU average daily census did not change significantly during the study period (12.8 in 2016 vs 11.8 in 2018). CONCLUSION: Value-added implementation of standardized diuretic utilization guidelines in the CTICU successfully reduced the use of high-charge diuretics without unfavorably impacting the quality of care delivery.

OBJECTIVE: Interstage readmissions are common in infants with single ventricle congenital heart disease undergoing staged surgical palliation. We retrospectively examined readmissions during the interstage period. DESIGN: Retrospective analysis. SETTING: The Heart Center at Nationwide Children's Hospital, Columbus, Ohio. PATIENTS: Newborns undergoing hybrid stage 1 palliation from January 2012 to December 2016 who survived to hospital discharge and were followed at our institution. INTERVENTIONS: All patients underwent hybrid stage 1 palliation. OUTCOME MEASURES: Outcomes included (1) reason for interstage readmission; (2) feeding modality during interstage period; (3) major interstage adverse events; and (4) interstage mortality. RESULTS: Study group comprised 57 patients. Five patients only admitted once during the interstage period for scheduled cardiac catheterization were included in the no readmission group. Therefore, 43 patients (75%) had a total of 87 interstage readmissions. Fourteen patients had 15 major interstage adverse events accounting for 17% of total readmissions. Stroke (n = 1); sepsis (n = 1); pericardial effusion requiring drainage (n = 1); mesenteric ischemia (n = 1); shock (n = 1); and cardiac catheterization requiring intervention (n = 11)-ductal stent balloon angioplasty (n = 3), enlargement of atrial septal defect/stent placement (n = 3), retrograde aortic arch stenosis (n = 4). Thirty-three readmissions were secondary to gastrointestinal/feeding issues; 15 cyanosis; 15 work of breathing; and 9 asymptomatic patients. Four patients suffered interstage deaths (7%). Five patients (9%) spent >30 days in the hospital during the interstage period. Of the 47 newborns (82%) discharged exclusively orally feeding, 74% remained all orally feeding throughout interstage period. No patient discharged with tube feedings learned to eat during the interstage period. CONCLUSION: Interstage readmissions are common in the hybrid patient population. Seventeen percent were secondary to major adverse events. Interstage mortality was 7%. Future studies to identify interventions aimed at decreasing feeding issues and viral bronchiolitis in this tenuous patient population will hopefully improve quality outcomes, reduce readmissions, and lessen health care costs.

INTRODUCTION: With increasing survival of children with HLHS and other single ventricle lesions, the complexity of medical care for these patients is substantial. Establishing and adhering to best practice models may improve outcome, but requires careful coordination and monitoring. METHODS: In 2013 our Heart Center began a process to build a comprehensive Single Ventricle Team designed to target these difficult issues. RESULTS: Comprehensive Single Ventricle Team in 2014 was begun, to standardize care for children with single ventricle heart defects from diagnosis to adulthood within our institution. The team is a multidisciplinary group of providers committed to improving outcomes and quality of life for children with single ventricle heart defects, all functioning within the medical home of our heart center. Standards of care were developed and implemented in five target areas to standardize medical management and patient and family support. Under the team 100 patients have been cared for. Since 2014 a decrease in interstage mortality for HLHS were seen. Using a team approach and the tools of Quality Improvement they have been successful in reaching high protocol compliance for each of these areas. CONCLUSIONS: This article describes the process of building a successful Single Ventricle team, our initial results, and lessons learned. Additional study is ongoing to demonstrate the effects of these interventions on patient outcomes.

BACKGROUND: Interstage mortality (IM) remains significant after stage 1 palliation (S1P) for single-ventricle heart disease (SVD), with many deaths sudden and unexpected. We sought to determine whether digoxin use post-S1P is associated with reduced IM, utilizing the multicenter database of the National Pediatric Cardiology Quality Improvement Collaborative (NPCQIC). METHODS AND RESULTS: From June 2008 to July 2013, 816 infants discharged after S1P from 50 surgical sites completed the interstage to stage II palliation, transplant, or IM. Arrhythmia during S1P hospitalization or discharge on antiarrhythmic medications were exclusions (n=270); 2 patients were lost to follow-up. Two analyses were performed: (1) propensity-score adjusted logistic regression with IM as outcome and (2) retrospective cohort analysis for patients discharged on digoxin versus not, matched for surgical site and other established IM risk factors. Of 544 study patients, 119 (21.9%) were discharged on digoxin. Logistic regression analysis with propensity score, site-size group, and digoxin use as predictor variables showed an increased risk of IM in those not discharged on digoxin (odds ratio, 8.6; lower confidence limit, 1.9; upper confidence limit, 38.3; P<0.01). The retrospective cohort analysis for 60 patients on digoxin (matched for site of care, type of S1P, post-S1P ECMO use, genetic syndrome, discharge feeding route, ventricular function, tricuspid regurgitation, and aortic arch gradient) showed 0% IM in the digoxin at discharge group and an estimated IM difference between the 2 groups of 9% (P=0.04). CONCLUSIONS: Among SVD infants in the NPCQIC database discharged post-S1P with no history of arrhythmia, use of digoxin at discharge was associated with reduced IM.

OBJECTIVE: To identify a cause for clinical deterioration, examine resuscitation efforts, and identify and correct system issues (thus improving outcomes) via a multidisciplinary code-review process soon after cardiopulmonary arrest. METHODS: Retrospective analysis of code events in a tertiary pediatric heart center from September 2010 to December 2013 and review of surgical-cardiac data from January 2010 to December 2013. RESULTS: A multidisciplinary team reviewed 47 code events, 16 of which (34%) were deemed potentially preventable. At least 2 issues were identified during 66% (31/47) of cardiopulmonary arrests reviewed. Key issues identified were related to communication (62%), environment/culture/policy (47%), patient care (including resuscitation, 41%), and equipment (38%). About 60% of reviewed arrests resulted in educational initiatives (eg, mock code, in-service education) and 47% resulted in a new policy or modification of existing policy. Less common were changes in equipment (32%) or modification of staffing needs (11%). Changes most frequently occurred in the unit specific to the event (68%) but some changes occurred throughout the Heart Center (32%) or across the hospital system (13%). Survival to discharge after cardiopulmonary arrest has improved over time (P = .03) to 81% for cardiac surgical patients in our center. CONCLUSION: A multidisciplinary code-review committee can identify deficiencies and lead to educational initiatives and improvements in care. When coupled with a hospital-wide "code blue" review process, these changes may benefit the institution as a whole.
