Bad behavior in healthcare: an insidious threat to patients, staff, and organizations.

PURPOSE OF REVIEW: 'Bad' or unprofessional behavior (UPB) destroys communication, teamwork, and professional wellbeing, presenting a significant threat to patients and staff. Understanding what constitutes 'bad' or UPB and creating broad accountability for its cessation is imperative to patient-centered care and the survival of the multidisciplinary health workforce. RECENT FINDINGS: Despite organizational and legislative commitments to provide well tolerated work environments, UPB is endemic in healthcare and continues to harm patients, staff, and organizations. Historically, categories of UPB have been researched separately which dilutes the problem. Typically, these behaviors cluster, are interchangeable, and are committed by same perpetrators. Women, junior staff, and minority groups remain the most prevalent targets. Even low intensity UPBs among health staff dramatically impacts risk to patient lives, limits quality care, and destroys staff wellbeing. Targeted interventions must address all five roles impacted by UPBs: the target, patients, bystanders, the perpetrator, and the organization to effectively eliminate UPBs. Organizational leaders must demonstrate and uphold organizational values and be swift in addressing UPB to limit the impact on teams and patients. SUMMARY: UPB in the healthcare setting presents a multifactorial threat to patients, staff, and organizations. To ensure the delivery of high-quality patient care, and the wellbeing of the health workforce it is crucial to understand the insidious impact of UPB and target interventions across all five roles.

Clinical Outcomes After Tracheostomy in Children With Single Ventricle Physiology: Collaborative Research From the Pediatric Cardiac Intensive Care Society Multicenter Cohort, 2010-2021.

OBJECTIVES: Multicenter studies reporting outcomes following tracheostomy in children with congenital heart disease are limited, particularly in patients with single ventricle physiology. We aimed to describe clinical characteristics and outcomes in a multicenter cohort of patients with single ventricle physiology who underwent tracheostomy before Fontan operation. DESIGN: Multicenter retrospective cohort study. SETTING: Twenty-one tertiary care pediatric institutions participating in the Collaborative Research from the Pediatric Cardiac Intensive Care Society. PATIENTS: We reviewed 99 children with single ventricle physiology who underwent tracheostomy before the Fontan operation at 21 institutions participating in Collaborative Research from the Pediatric Cardiac Intensive Care Society between January 2010 and December 2020, with follow-up through December 31, 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Death occurred in 51 of 99 patients (52%). Cox proportional hazard analysis was performed to determine factors associated with death after tracheostomy. Results are presented as hazard ratio (HR) with 95% CIs. Nonrespiratory indication(s) for tracheostomy (HR, 2.21; 95% CI, 1.14-4.32) and number of weeks receiving mechanical ventilation before tracheostomy (HR, 1.06; 95% CI, 1.02-1.11) were independently associated with greater hazard of death. In contrast, diagnosis of tricuspid atresia or Ebstein's anomaly was associated with less hazard of death (HR, 0.16; 95% CI, 0.04-0.69). Favorable outcome, defined as survival to Fontan operation or decannulation while awaiting Fontan operation with viable cardiopulmonary physiology, occurred in 29 of 99 patients (29%). Median duration of mechanical ventilation before tracheostomy was shorter in patients who survived to favorable outcome (6.1 vs. 12.1 wk; p < 0.001), and only one of 16 patients with neurologic indications for tracheostomy and 0 of ten patients with cardiac indications for tracheostomy survived to favorable outcome. CONCLUSIONS: For children with single ventricle physiology who undergo tracheostomy, mortality risk is high and should be carefully considered when discussing tracheostomy as an option for these children. Favorable outcomes are possible, although thoughtful attention to patient selection and tracheostomy timing are likely necessary to achieve this goal.

ALCAPA in Children with Complex Congenital Heart Disease: A Multicenter Study.

We sought to report characteristics and outcomes of children with complex anomalous left coronary artery from the pulmonary artery (ALCAPA) and to compare the outcomes to children with isolated ALCAPA. We performed a retrospective data analysis of children with ALCAPA who underwent cardiac surgery between 1/2009 and 3/2018 at 21 centers. Characteristics and outcomes of patients with complex ALCAPA are provided using descriptive statistics. Outcomes were compared between complex ALCAPA and isolated ALCAPA using Fisher's exact test. We reviewed 258 patients who underwent surgical repair of ALCAPA at 21 centers. We identified 10 patients (3.9%) with complex ALCAPA. Median age at initial cardiac surgery was 49 days (range: 4 days, 12.8 years). Cardiac lesions associated with ALCAPA were HLHS (n = 3); scimitar syndrome (n = 2); VSD with aortic coarctation (n = 2); VSD with right pulmonary artery discontinuity (1); DORV with mitral atresia (n = 1); and ToF (n = 1). ALCAPA was diagnosed prior to surgical intervention in 1 patient; during the initial cardiac surgery in 4 patients; in the early postoperative period via cardiac catheterization in 3 patients; and later in childhood after initial surgical repair in 2 patients. Following ALCAPA repair, patients with complex ALCAPA, as compared to patients with isolated ALCAPA, were more likely to be placed on ECMO (50% vs 12%, p = 0.002), receive CPR (30% vs 6%, p = 0.017), or suffer operative mortality (50% vs 3%, p < 0.001). Complex ALCAPA is uncommon. All but one with complex ALCAPA was not diagnosed preoperatively and postoperative morbidity and mortality were significantly greater in these complex patients compared to patients with isolated ALCAPA.

Anomalous Origin of the Left Coronary Artery From the Pulmonary Artery: A Retrospective Multicenter Study.

OBJECTIVES: We aimed to describe characteristics and operative outcomes from a multicenter cohort of infants who underwent repair of anomalous left coronary artery from the pulmonary artery. We also aimed to identify factors associated with major adverse cardiovascular events following anomalous left coronary artery from the pulmonary artery repair. DESIGN: Retrospective chart review. SETTING: Twenty-one tertiary-care referral centers. PATIENTS: Infants less than 365 days old who underwent anomalous left coronary artery from the pulmonary artery repair. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Major adverse cardiovascular events were defined as the occurrence of postoperative extracorporeal membrane oxygenation, cardiopulmonary resuscitation, left ventricular assist device, heart transplantation, or operative mortality. Factors independently associated with major adverse cardiovascular events were identified using multivariable logistic regression analysis. We reviewed 177 infants (< 365 d old) who underwent anomalous left coronary artery from the pulmonary artery repair between January 2009 and March 2018. Major adverse cardiovascular events occurred in 36 patients (20%). Twenty-nine patients (16%) received extracorporeal membrane oxygenation, 14 (8%) received cardiopulmonary resuscitation, four (2%) underwent left ventricular assist device placement, two (1%) underwent heart transplantation, and six (3.4%) suffered operative mortality. In multivariable analysis, preoperative inotropic support (odds ratio, 3.5; 95% CI, 1.4-8.5), cardiopulmonary bypass duration greater than 150 minutes (odds ratio, 6.9 min; 95% CI, 2.9-16.7 min), and preoperative creatinine greater than 0.3 mg/dL (odds ratio, 2.4 mg/dL; 95% CI, 1.1-5.6 mg/dL) were independently associated with major adverse cardiovascular events. In patients with preoperative left ventricular end-diastolic diameter measurements available (n = 116), left ventricular end-diastolic diameter z score greater than 6 was also independently associated with major adverse cardiovascular events (odds ratio, 7.6; 95% CI, 2.0-28.6). CONCLUSIONS: In this contemporary multicenter analysis, one in five children who underwent surgical repair of anomalous left coronary artery from the pulmonary artery experienced major adverse cardiovascular events. Preoperative characteristics such as inotropic support, creatinine, and left ventricular end-diastolic diameter z score should be considered when planning for potential postoperative complications.

Multicenter Analysis of Truncal Valve Management and Outcomes in Children with Truncus Arteriosus.

Truncal valve management in patients with truncus arteriosus is a clinical challenge, and indications for truncal valve intervention have not been defined. We sought to evaluate truncal valve dysfunction and primary valve intervention in patients with truncus arteriosus and determine risk factors for later truncal valve intervention. We conducted a retrospective cohort study of children who underwent truncus arteriosus repair at 15 centers between 2009 and 2016. Multivariable competing risk analysis was performed to determine risk factors for later truncal valve intervention. We reviewed 252 patients. Forty-two patients (17%) underwent truncal valve intervention during their initial surgery. Postoperative extracorporeal support, CPR, and operative mortality for patients who underwent truncal valve interventions were statistically similar to the rest of the cohort. Truncal valve interventions were performed in 5 of 64 patients with mild insufficiency; 5 of 16 patients with mild-to-moderate insufficiency; 17 of 35 patients with moderate insufficiency; 5 of 9 patients with moderate-to-severe insufficiency; and all 10 patients with severe insufficiency. Twenty patients (8%) underwent later truncal valve intervention, five of whom had no truncal valve intervention during initial surgical repair. Multivariable analysis revealed truncal valve intervention during initial repair (HR 11.5; 95% CI 2.5, 53.2) and moderate or greater truncal insufficiency prior to initial repair (HR 4.0; 95% CI 1.1, 14.5) to be independently associated with later truncal valve intervention. In conclusion, in a multicenter cohort of children with truncus arteriosus, 17% had truncal valve intervention during initial surgical repair. For patients in whom variable truncal valve insufficiency is present and primary intervention was not performed, late interventions were uncommon. Conservative surgical approach to truncal valve management may be justifiable.

Assuring Sustainable Gains in Interdisciplinary Performance Improvement: Creating a Shared Mental Model During Operating Room to Cardiac ICU Handoff.

OBJECTIVE: To understand sustainability and assure long-term gains in multidisciplinary performance improvement using an operating room to cardiac ICU handoff process focused on creation of a shared mental model. DESIGN: Performance improvement cohort project with pre- and postintervention assessments spanning a 4-year period. SETTING: Twenty-six bed pediatric cardiac ICU in a tertiary care children's hospital. PATIENTS: Cardiac surgery patients admitted to cardiac ICU from the operating room following cardiac surgery. INTERVENTIONS: An interdisciplinary workgroup overhauled our handoff process in 2010. The new algorithm emphasized role delineation, standardized communication, and creation of a shared mental model. Our "I-5" mnemonic allowed validation and verification of a shared mental model between multidisciplinary teams. Staff orientation and practice guidelines were revised to incorporate the new process, visual aids were distributed and posted at each patient's bedside, and lapses/audit data were discussed in multidisciplinary forum. MEASUREMENTS AND MAIN RESULTS: Audits assessing equipment and information transfer during handoff were performed 8 weeks following implementation (n = 29), repeated at 1 year (n = 37), 3 years (n = 15), and 4 years (n = 50). Staff surveys prior to implementation, at 8 weeks, and 4 years postintervention assessed satisfaction. Comprehensiveness of information transfer improved in the 4 years following implementation, and staff satisfaction was maintained. At 4 years, discussion of all elements of information transfer was 94%, increased from 85% 8 weeks following implementation and discussion of four or more information elements was 100% increased from 93%. Of the 73% of staff who completed the survey at 4 years, 91% agreed that they received all necessary information, and 87% agreed that the handoff resulted in a shared mental model. CONCLUSIONS: Our methods were effective in creating and sustaining high levels of staff communication and adherence to the new process, thus achieving sustainable gains. Performance improvement initiatives require proactive interdisciplinary maintenance to be successful long term.

The Pediatric Heart Center Melting Pot: Sharing Recipes for Success: Proceedings from the 8th World Congress of Pediatric Cardiology and Cardiac Surgery.

The challenges of present-day healthcare are urgent; there is a shortage of clinicians, patient care is increasingly complex, resources are limited, clinician turnover seems ever-increasing, and the expectations of providers and patients are monumental. To transform problems into innovative opportunities, diverse perspectives and a sense of possibility are needed. The following is a collaborative manuscript authored by the speakers of the 8th World Congress of Pediatric Cardiology and Cardiac Surgery session, "Teamwork, Culture Change, and Strategy." Although this panel was diverse in the clinical roles, nationalities, and genders represented, several consistent themes emerged which are explored in this work.

Contemporary Multicenter Outcomes for Truncus Arteriosus With Interrupted Aortic Arch.

BACKGROUND: Truncus arteriosus with interrupted aortic arch (TA-IAA) is a rare congenital heart defect with historically poor outcomes. Contemporary multicenter data are limited. METHODS: A retrospective cohort study of children who underwent repair of TA-IAA between 2009 and 2016 at 12 tertiary care referral centers within the United States was performed. Major adverse cardiac events (MACE) were defined as postoperative extracorporeal membrane oxygenation, cardiopulmonary resuscitation, or operative mortality. TA-IAA patients were compared with TA patients who underwent repair during the study period from the same institutions. RESULTS: We reviewed 35 patients with TA-IAA. MACE occurred in 12 patients (34%). Improvement over time was observed during the study period with 11 events (92%) occurring in the first half of the study period (P = .03). Factors associated with MACE included moderate or severe truncal valve insufficiency (P < .01), concomitant truncal valve repair (P = .04), and longer cardiopulmonary bypass duration (P = .02). In comparison with 216 patients who underwent TA repair, patients with TA-IAA had a higher rate of MACE, but this finding was not statistically significant (34% vs 20%, respectively; P = .07). Additionally no differences between TA-IAA and TA groups were observed for unplanned reoperations (14% vs 22%, respectively; P = .3), hospital length of stay (24 vs 23 days, P = .65), or late deaths (7% vs 7%, P = 1.00). CONCLUSIONS: In this contemporary, multicenter cohort the rate of MACE after repair of TA-IAA was high but improved during the study period. Early childhood outcomes of patients with TA-IAA were similar to those with TA.

Cardiac Arrest in Children Following Cardiac Surgery: A Scoping Review of Contributing Factors.

Nearly half of children experiencing cardiac arrest following cardiac surgery do not survive hospital discharge and patients who survive often experience significant neurological impairment. Additionally, increased resource utilization following cardiac arrest translates into adverse logistical and financial consequences. Although some studies have identified patient characteristics that increase the risk of cardiac arrest after pediatric cardiac surgery, modifiable risk factors, which could provide a foundation for effective prevention strategies, have been elusive. This scoping review explores the current knowledge surrounding risk factors associated with cardiac arrest in children following cardiac surgery and provides recommendations for future research.

Evaluation of Pediatric Cardiac Intensive Care Advanced Practice Provider's Leadership Education and Experience During Emergencies.

BACKGROUND: The number of advanced practice providers (APPs) in pediatric critical care has increased dramatically over recent years, leading to increased opportunities to lead resuscitation teams during pediatric emergent events. OBJECTIVES: The aim of this study was to better understand the emergency leadership experience, training, and education that pediatric cardiac intensive care unit APPs receive. METHODS: This study was a cross-sectional descriptive studying using survey responses. The self-administered survey was administered to APP and attending physician members of the Pediatric Cardiac Intensive Care Society. Survey results were analyzed. RESULTS: One hundred seven pediatric cardiac intensive care unit APPs (n = 53) and attending physicians (n = 54) responded to the survey. Half of APPs felt that attendings allowed APPs to lead emergent events, and 50.9% had never functioned in the team leader role. Most respondents (77.5%) rated their comfort functioning in the role during emergent situations as moderate or lower. Increased APP experience level was associated with a higher number of codes led, increased comfort leading codes, and improved mental model sharing (all Ps < .0001). The number of codes an APP had previously led was associated with increased comfort leading codes (P < .0001) and mental model sharing (P = .0002). One-third of attendings said they allow APPs to lead codes in their unit. Half of attendings who do not allow APPs to function as the team leader would follow formal training. DISCUSSION: Opportunities for APPs to function as team leaders during emergent events continue to increase. A leadership educational program would be beneficial to pediatric critical care APPs. It may also have the additional benefit of improving physician comfort with APPs leading code events and patient outcomes.

Shifting the Paradigm: A Quality Improvement Approach to Proactive Cardiac Arrest Reduction in the Pediatric Cardiac Intensive Care Unit.

INTRODUCTION: Children with cardiac conditions are at higher risk of in-hospital pediatric cardiopulmonary arrest (CA), resulting in significant morbidity and mortality. Despite the elevated risk, proactive cardiac arrest prevention programs in the cardiac intensive care unit (CICU) remain underdeveloped. Our team developed a multidisciplinary program centered on developing a quality improvement (QI) bundle for patients at high risk of CA. METHODS: This project occurred in a 26-bed pediatric CICU of a tertiary care children's hospital. Statistical process control methodology tracked changes in CA rates over time. The global aim was to reduce CICU mortality; the smart aim was to reduce the CA rate by 50% over 12 months. Interprofessional development and implementation of a QI bundle included visual cues to identify high-risk patients, risk mitigation strategies, a new rounding paradigm, and defined escalation algorithms. Additionally, weekly event and long-term data reviews, arrest debriefs, and weekly unit-wide dissemination of key findings supported a culture change. RESULTS: After bundle implementation, CA rates decreased by 68% compared to baseline and 45% from the historical baseline. Major complications decreased from 17.1% to 12.6% (P < 0.001) and mortality decreased from 5.7% to 5.0% (P = 0.048). These results were sustained for 30 months. CONCLUSIONS: Cardiac arrest is a modifiable, rather than inevitable, metric in the CICU. Reduction is achievable through the interprofessional implementation of bundled interventions targeting proactive CA prevention. Once incorporated into widespread efforts to engage multidisciplinary CICU stakeholders, these patient-focused interventions resulted in sustained improvement.

Rapid Identity and Quantity CQA Test for Multivalent mRNA Drug Product Formulations.

The COVID-19 pandemic highlighted mRNA as a promising platform for vaccines and therapeutics. Many of the analytical tools used to characterize the critical quality attributes of mRNA are inherently singleplex and are not necessarily optimal from a labor and cost perspective. Here, we demonstrate the feasibility of a multiplexed platform (VaxArray) for efficient identity verification and concentration determination for both monovalent and multivalent mRNA formulations. A model system comprising mRNA constructs for influenza hemagglutinin and neuraminidase was used to characterize the analytical performance metrics for a VaxArray mRNA assay. The assay presented herein had a time to result of less than 2 h, required no PCR-based amplification nor extraction of mRNA from lipid nanoparticles, and exhibited high construct specificity that enabled application to the bivalent mixture. The sensitivity for influenza hemagglutinin and neuraminidase mRNA was sub-µg/mL, which is vaccine-relevant, and the average accuracy (%recovery of a check standard) and precision were 104 ± 2% and 9 ± 2%, respectively.

Characteristics and Surgical Outcomes of Patients With Late Presentation of Anomalous Left Coronary Artery From the Pulmonary Artery: A Multicenter Study.

We sought to describe the clinical course and outcomes of patients who are diagnosed with anomalous left coronary artery from the pulmonary artery (ALCAPA) after infancy. We conducted a retrospective evaluation of patients who underwent ALCAPA surgery between January 2009 to March 2018 at 21 US centers. Clinical presentation, inpatient management, and postoperative outcomes of patients repaired ≥1 year of age were described. To characterize this cohort, we compared these data to patients repaired before 1 year of age. Of 248 ALCAPA patients, 71 (29%) underwent repair ≥1 year of age. Among this subset, the median age at diagnosis was 8.3 years. Chronic arrhythmia occurred in 7%. Patients had good postoperative recovery of left ventricle (LV) dysfunction (90%) and LV dilation (75%), although a low incidence of recovery of mitral regurgitation (40%). Compared to infants, older patients were more likely to present with cardiac arrest (11% vs 1%) and less likely to have moderate or worse LV dysfunction or mitral regurgitation. Older patients had significantly less postoperative extracorporeal membrane oxygenation use, and shorter ICU and hospital stay. In the older cohort, operative mortality occurred in only 1 patient and no patient died after discharge (median follow-up 2.7 years). Survival of patients who presented with ALCAPA beyond infancy was excellent, although chronic mitral regurgitation and chronic arrhythmia were not uncommon. Patients who underwent ALCAPA repair ≥1 year of age were less likely to present with LV dysfunction but more likely to present with cardiac arrest than younger patients.

Multicenter Analysis of Early Childhood Outcomes After Repair of Truncus Arteriosus.

BACKGROUND: Literature describing morbidity and mortality after truncus arteriosus repair is predominated by single-center reports. We created and analyzed a multicenter dataset to identify risk factors for late mortality and right ventricle-to-pulmonary artery (RV-PA) conduit reintervention for this patient population. METHODS: We retrospectively collected data on children who underwent repair of truncus arteriosus without concomitant arch obstruction at 15 centers between 2009 and 2016. Cox regression survival analysis was conducted to determine risk factors for late mortality, defined as death occurring after hospital discharge and greater than 30 days after operation. Probability of any RV-PA conduit reintervention was analyzed over time using Fine-Gray modeling. RESULTS: We reviewed 216 patients with median follow-up of 2.9 years (range, 0.1 to 8.8). Operative mortality occurred in 15 patients (7%). Of the 201 survivors there were 14 (7%) late deaths. DiGeorge syndrome (hazard ratio [HR], 5.4; 95% confidence interval [CI], 1.6 to 17.8) and need for postoperative tracheostomy (HR, 5.9; 95% CI, 1.8 to 19.4) were identified as independent risk factors for late mortality. At least one RV-PA conduit catheterization or surgical reintervention was performed in 109 patients (median time to reintervention, 23 months; range, 0.3 to 93). Risk factors for reintervention included use of pulmonary or aortic homografts versus Contegra (Medtronic, Inc, Minneapolis, MN) bovine jugular vein conduits (HR, 1.9; 95% CI, 1.2 to 3.1) and smaller conduit size (HR per mm/m2, 1.05; 95% CI, 1.03 to 1.08). CONCLUSIONS: In a multicenter dataset DiGeorge syndrome and need for tracheostomy postoperatively were found to be independent risk factors for late mortality after repair of truncus arteriosus, whereas risk of conduit reintervention was independently influenced by both initial conduit type and size.

Characteristics and operative outcomes for children undergoing repair of truncus arteriosus: A contemporary multicenter analysis.

OBJECTIVE: We sought to describe characteristics and operative outcomes of children who underwent repair of truncus arteriosus and identify risk factors for the occurrence of major adverse cardiac events (MACE) in the immediate postoperative period in a contemporary multicenter cohort. METHODS: We conducted a retrospective review of children who underwent repair of truncus arteriosus between 2009 and 2016 at 15 centers within the United States. Patients with associated interrupted or obstructed aortic arch were excluded. MACE was defined as the need for postoperative extracorporeal membrane oxygenation, cardiopulmonary resuscitation, or operative mortality. Risk factors for MACE were identified using multivariable logistic regression analysis and reported as odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: We reviewed 216 patients. MACE occurred in 44 patients (20%) and did not vary significantly over time. Twenty-two patients (10%) received postoperative extracorporeal membrane oxygenation, 26 (12%) received cardiopulmonary resuscitation, and 15 (7%) suffered operative mortality. With multivariable logistic regression analysis (which included adjustment for center effect), factors independently associated with MACE were failure to diagnose truncus arteriosus before discharge from the nursery (OR, 3.1; 95% CI, 1.3-7.4), cardiopulmonary bypass duration >150 minutes (OR, 3.5; 95% CI, 1.5-8.5), and right ventricle-to-pulmonary artery conduit diameter >50 mm/m2 (OR, 4.7; 95% CI, 2.0-11.1). CONCLUSIONS: In a contemporary multicenter analysis, 20% of children who underwent repair of truncus arteriosus experienced MACE. Early diagnosis, shorter duration of cardiopulmonary bypass, and use of smaller diameter right ventricle-to-pulmonary artery conduits represent potentially modifiable factors that could decrease morbidity and mortality in this fragile patient population.

Utilization of inhaled nitric oxide after surgical repair of truncus arteriosus: A multicenter analysis.

BACKGROUND: Elevated pulmonary vascular resistance (PVR) is common following repair of truncus arteriosus. Inhaled nitric oxide (iNO) is an effective yet costly therapy that is frequently implemented postoperatively to manage elevated PVR. OBJECTIVES: We aimed to describe practice patterns of iNO use in a multicenter cohort of patients who underwent repair of truncus arteriosus, a lesion in which recovery is often complicated by elevated PVR. We also sought to identify patient and center factors that were more commonly associated with the use of iNO in the postoperative period. DESIGN: Retrospective cohort study. SETTING: 15 tertiary care pediatric referral centers. PATIENTS: All infants who underwent definitive repair of truncus arteriosus without aortic arch obstruction between 2009 and 2016. INTERVENTIONS: Descriptive statistics were used to demonstrate practice patterns of iNO use. Bivariate comparisons of characteristics of patients who did and did not receive iNO were performed, followed by multivariable mixed logistic regression analysis using backward elimination to identify independent predictors of iNO use. MAIN RESULTS: We reviewed 216 patients who met inclusion criteria, of which 102 (46%) received iNO in the postoperative period: 69 (68%) had iNO started in the operating room and 33 (32%) had iNO initiated in the ICU. Median duration of iNO use was 4 days (range: 1-21 days). In multivariable mixed logistic regression analysis, use of deep hypothermic circulatory arrest (odds ratio: 3.2; 95% confidence interval: 1.2, 8.4) and center (analyzed as a random effect, p = .02) were independently associated with iNO use. CONCLUSIONS: In this contemporary multicenter study, nearly half of patients who underwent repair of truncus arteriosus received iNO postoperatively. Use of iNO was more dependent on individual center practice rather than patient characteristics. The study suggests a need for collaborative quality initiatives to determine optimal criteria for utilization of this important but expensive therapy.

Continuous Capnography in Pediatric Intensive Care.

Capnography or end-tidal carbon dioxide (Etco2) monitoring has a variety of uses in the pediatric intensive care setting. The ability to continuously measure exhaled carbon dioxide can provide vital information about airway, breathing, and circulation in critically ill pediatric patients. Capnography has diagnosis-specific applications for pediatric patients with congenital heart disease, reactive airway disease, neurologic emergencies, and metabolic derangement. This modality allows for noninvasive monitoring and has become the standard of care. This article reviews the basic principles and clinical applications of Etco2 monitoring in the pediatric intensive care unit.
