An International Survey Comparing Different Physician Models for Health Care Delivery to Critically Ill Children With Heart Disease.

OBJECTIVES: To explore relationships between the training background of cardiac critical care attending physicians and self-reported perceived strengths and weaknesses in their ability to provide clinical care. DESIGN: Cross-sectional observational survey sent worldwide to ~550 practicing cardiac ICU attending physicians. SETTING: Hospitals providing cardiac critical care. SUBJECTS: Practicing cardiac critical care physicians. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We received responses from 243 ICU attending physicians from 82 centers (14 countries). The primary training background of the respondents included critical care (62%), dual training in critical care and cardiology (16%), cardiology (14%), and other (8%). We received 49 responses from medical directors in nine countries, who reported that the predominant training background for attending physicians who provide cardiac intensive care at their institutions were critical care (58%), dual trained (18%), cardiology (12%), and other (11%). A greater proportion of physicians trained in either critical care or dual-training reported feeling confident managing multiple organ failure, neurologic conditions, brain death, cardiac arrest, and performing procedures like advanced airway placement and inserting chest- and abdominal-drains. In contrast, physicians with cardiology and dual-training reported feeling more confident managing intractable arrhythmias, understanding cardiopulmonary interactions, and interpreting echocardiogram, electrocardiogram, and cardiac catheterization. Overall, only 57% of the respondents felt comfortable based on their current training background to manage patients with complex cardiac issues without collaboration with other specialists. CONCLUSIONS: Our survey demonstrates that intensivists trained in critical care are more comfortable with critical care skills, cardiology-trained intensivists are more comfortable with cardiology skills, and dual-trained physicians are comfortable with both critical care skills and cardiology skills. These findings may help inform future efforts to optimize the educational curriculum and training pathways for future cardiac intensivists. These data may also be used to shape continuing medical education activities for cardiac intensivists who have already completed their training.

Criteria for Critical Care Infants and Children: PICU Admission, Discharge, and Triage Practice Statement and Levels of Care Guidance.

OBJECTIVES: To update the American Academy of Pediatrics and Society of Critical Care Medicine's 2004 Guidelines and levels of care for PICU. DESIGN: A task force was appointed by the American College of Critical Care Medicine to follow a standardized and systematic review of the literature using an evidence-based approach. The 2004 Admission, Discharge and Triage Guidelines served as the starting point, and searches in Medline (Ovid), Embase (Ovid), and PubMed resulted in 329 articles published from 2004 to 2016. Only 21 pediatric studies evaluating outcomes related to pediatric level of care, specialized PICU, patient volume, or personnel. Of these, 13 studies were large retrospective registry data analyses, six small single-center studies, and two multicenter survey analyses. Limited high-quality evidence was found, and therefore, a modified Delphi process was used. Liaisons from the American Academy of Pediatrics were included in the panel representing critical care, surgical, and hospital medicine expertise for the development of this practice guidance. The title was amended to "practice statement" and "guidance" because Grading of Recommendations, Assessment, Development, and Evaluation methodology was not possible in this administrative work and to align with requirements put forth by the American Academy of Pediatrics. METHODS: The panel consisted of two groups: a voting group and a writing group. The panel used an iterative collaborative approach to formulate statements on the basis of the literature review and common practice of the pediatric critical care bedside experts and administrators on the task force. Statements were then formulated and presented via an online anonymous voting tool to a voting group using a three-cycle interactive forecasting Delphi method. With each cycle of voting, statements were refined on the basis of votes received and on comments. Voting was conducted between the months of January 2017 and March 2017. The consensus was deemed achieved once 80% or higher scores from the voting group were recorded on any given statement or where there was consensus upon review of comments provided by voters. The Voting Panel was required to vote in all three forecasting events for the final evaluation of the data and inclusion in this work. The writing panel developed admission recommendations by level of care on the basis of voting results. RESULTS: The panel voted on 30 statements, five of which were multicomponent statements addressing characteristics specific to PICU level of care including team structure, technology, education and training, academic pursuits, and indications for transfer to tertiary or quaternary PICU. Of the remaining 25 statements, 17 reached consensus cutoff score. Following a review of the Delphi results and consensus, the recommendations were written. CONCLUSIONS: This practice statement and level of care guidance manuscript addresses important specifications for each PICU level of care, including the team structure and resources, technology and equipment, education and training, quality metrics, admission and discharge criteria, and indications for transfer to a higher level of care. The sparse high-quality evidence led the panel to use a modified Delphi process to seek expert opinion to develop consensus-based recommendations where gaps in the evidence exist. Despite this limitation, the members of the Task Force believe that these recommendations will provide guidance to practitioners in making informed decisions regarding pediatric admission or transfer to the appropriate level of care to achieve best outcomes.

Clinical practice parameters for hemodynamic support of pediatric and neonatal septic shock: 2007 update from the American College of Critical Care Medicine.

BACKGROUND: The Institute of Medicine calls for the use of clinical guidelines and practice parameters to promote "best practices" and to improve patient outcomes. OBJECTIVE: 2007 update of the 2002 American College of Critical Care Medicine Clinical Guidelines for Hemodynamic Support of Neonates and Children with Septic Shock. PARTICIPANTS: Society of Critical Care Medicine members with special interest in neonatal and pediatric septic shock were identified from general solicitation at the Society of Critical Care Medicine Educational and Scientific Symposia (2001-2006). METHODS: The Pubmed/MEDLINE literature database (1966-2006) was searched using the keywords and phrases: sepsis, septicemia, septic shock, endotoxemia, persistent pulmonary hypertension, nitric oxide, extracorporeal membrane oxygenation (ECMO), and American College of Critical Care Medicine guidelines. Best practice centers that reported best outcomes were identified and their practices examined as models of care. Using a modified Delphi method, 30 experts graded new literature. Over 30 additional experts then reviewed the updated recommendations. The document was subsequently modified until there was greater than 90% expert consensus. RESULTS: The 2002 guidelines were widely disseminated, translated into Spanish and Portuguese, and incorporated into Society of Critical Care Medicine and AHA sanctioned recommendations. Centers that implemented the 2002 guidelines reported best practice outcomes (hospital mortality 1%-3% in previously healthy, and 7%-10% in chronically ill children). Early use of 2002 guidelines was associated with improved outcome in the community hospital emergency department (number needed to treat = 3.3) and tertiary pediatric intensive care setting (number needed to treat = 3.6); every hour that went by without guideline adherence was associated with a 1.4-fold increased mortality risk. The updated 2007 guidelines continue to recognize an increased likelihood that children with septic shock, compared with adults, require 1) proportionally larger quantities of fluid, 2) inotrope and vasodilator therapies, 3) hydrocortisone for absolute adrenal insufficiency, and 4) ECMO for refractory shock. The major new recommendation in the 2007 update is earlier use of inotrope support through peripheral access until central access is attained. CONCLUSION: The 2007 update continues to emphasize early use of age-specific therapies to attain time-sensitive goals, specifically recommending 1) first hour fluid resuscitation and inotrope therapy directed to goals of threshold heart rates, normal blood pressure, and capillary refill 70% and cardiac index 3.3-6.0 L/min/m.

Executive Summary: Criteria for Critical Care of Infants and Children: PICU Admission, Discharge, and Triage Practice Statement and Levels of Care Guidance.

This is an executive summary of the 2019 update of the 2004 guidelines and levels of care for PICU. Since previous guidelines, there has been a tremendous transformation of Pediatric Critical Care Medicine with advancements in pediatric cardiovascular medicine, transplant, neurology, trauma, and oncology as well as improvements of care in general PICUs. This has led to the evolution of resources and training in the provision of care through the PICU. Outcome and quality research related to admission, transfer, and discharge criteria as well as literature regarding PICU levels of care to include volume, staffing, and structure were reviewed and included in this statement as appropriate. Consequently, the purposes of this significant update are to address the transformation of the field and codify a revised set of guidelines that will enable hospitals, institutions, and individuals in developing the appropriate PICU for their community needs. The target audiences of the practice statement and guidance are broad and include critical care professionals; pediatricians; pediatric subspecialists; pediatric surgeons; pediatric surgical subspecialists; pediatric imaging physicians; and other members of the patient care team such as nurses, therapists, dieticians, pharmacists, social workers, care coordinators, and hospital administrators who make daily administrative and clinical decisions in all PICU levels of care.

Improving communication in a pediatric intensive care unit using daily patient goal sheets.

PURPOSE: The aim of the study was to determine if a pediatric intensive care unit (PICU) daily patient goal sheet would improve communication between health care providers and decrease length of stay (LOS). MATERIALS AND METHODS: We evaluated a daily patient goal sheet's impact on questionnaire-based measures of effectiveness of communication, nurses' knowledge of physicians in charge, and on LOS in the PICU. RESULTS: Four hundred nineteen questionnaires were completed by nurses and physicians before goal sheet implementation and 387 after implementation. Nurses and physicians perceived an improved understanding of patient care goals (P < .001), reported increased comfort in explaining patient care goals to parents (P < .001), and listed a higher number of patient care goals after goal sheet implementation (P < .01). Nurses identified the patient's attending physician and fellow with increased accuracy after goal sheet implementation (P < .001). Median PICU LOS was unchanged; however, mean LOS trended toward a reduction after goal sheet implementation (4.1 vs 3.7 days, P = .36). Seventy-six percent of respondents found the goal sheets helpful. CONCLUSIONS: Using a PICU daily patient goal sheet can improve communication between health care providers, help nurses identify the in-charge physicians, and be helpful for patient care. By explicitly documenting patient care goals, there is enhanced clarity of patient care plans between health care providers.

Effect of a rapid response team on hospital-wide mortality and code rates outside the ICU in a Children's Hospital.

CONTEXT: Introduction of a rapid response team (RRT) has been shown to decrease mortality and cardiopulmonary arrests outside of the intensive care unit (ICU) in adult inpatients. No published studies to date show significant reductions in mortality or cardiopulmonary arrests in pediatric inpatients. OBJECTIVE: To determine the effect on hospital-wide mortality rates and code rates outside of the ICU setting after RRT implementation at an academic children's hospital. DESIGN, SETTING, AND PARTICIPANTS: A cohort study design with historical controls at a 264-bed, free-standing, quaternary care academic children's hospital. Pediatric inpatients who spent at least 1 day on a medical or surgical ward between January 1, 2001, and March 31, 2007, were included. A total of 22,037 patient admissions and 102,537 patient-days were evaluated preintervention (before September 1, 2005), and 7257 patient admissions and 34,420 patient-days were evaluated postintervention (on or after September 1, 2005). INTERVENTION: The RRT included a pediatric ICU-trained fellow or attending physician, ICU nurse, ICU respiratory therapist, and nursing supervisor. This team was activated using standard criteria and was available at all times to assess, treat, and triage decompensating pediatric inpatients. MAIN OUTCOME MEASURES: Hospital-wide mortality rates and code (respiratory and cardiopulmonary arrests) rates outside of the ICU setting. All outcomes were adjusted for case mix index values. RESULTS: After RRT implementation, the mean monthly mortality rate decreased by 18% (1.01 to 0.83 deaths per 100 discharges; 95% confidence interval [CI], 5%-30%; P = .007), the mean monthly code rate per 1000 admissions decreased by 71.7% (2.45 to 0.69 codes per 1000 admissions), and the mean monthly code rate per 1000 patient-days decreased by 71.2% (0.52 to 0.15 codes per 1000 patient-days). The estimated code rate per 1000 admissions for the postintervention group was 0.29 times that for the preintervention group (95% likelihood ratio CI, 0.10-0.65; P = .008), and the estimated code rate per 1000 patient-days for the postintervention group was 0.28 times that for the preintervention group (95% likelihood ratio CI, 0.10-0.64; P = .007). CONCLUSION: Implementation of an RRT was associated with a statistically significant reduction in hospital-wide mortality rate and code rate outside of the pediatric ICU setting.

The hemophagocytic syndrome: titrating continuous hemofiltration to the degree of lactic acidosis.

In 3 cases of severe multiple organ failure due to hemophagocytic lymphohistiocytosis (HLH) in children, the authors demonstrate the utility of continuous hemofiltration in attenuating the consequences of excess cytokine activity, with therapy titrated to the degree of lactic acidosis. HLH was diagnosed in 3 encephalopathic children with multiple organ failure, elevated ferritin (49,396-237,582 pmol/L; or 21,983-105,733 ng/mL), elevated serum triglyceride, and depressed cell lines. One had a known malignancy, one had EBV-associated lymphoproliferative disease, and one was previously healthy. Continuous hemofiltration was initiated, with the ultrafiltrate production rate and countercurrent dialysate flow titrated to metabolic acidosis as reflected by the serum lactate (maximum 3.5 mmol/L or 31.6 mg/dL). Hemofiltration was titrated upward until lactic acidosis resolved, through clearance of lactate or interruption of excess cytokine-driven activity; maximum prescription was 2000 mL/h ultrafiltrate production plus 2500 mL/h dialysate flow. Stability was achieved with hemofiltration, then substantial resolution occurred with treatment according to the HLH-94 protocol (dexamethasone, cyclosporin, VP-16, intrathecal methotrexate). One child succumbed to candidiasis. Another made a full recovery. A third succumbed to his primary malignancy. HLH should be suspected in unexplained or unresolving multiple organ failure. Titration of hemofiltration based on measurable parameters of cellular metabolism (e.g., lactate, base deficit) may stabilize the child with metabolic acidosis long enough to allow proper diagnosis and institution of definitive therapy. Hemofiltration is not a panacea but rather a stabilizing mechanism, with poorly understood effects on interstitial water and solute flux, that facilitates recovery over weeks, not days.

Identification of Epstein-Barr virus-specific CD8+ T lymphocytes in the circulation of pediatric transplant recipients.

BACKGROUND: Pediatric transplant recipients are at increased risk for Epstein Barr virus (EBV)-related B cell lymphomas. In healthy individuals, the expansion of EBV-infected B cells is controlled by CD8+ cytotoxic T cells. However, immunosuppressive therapy may compromise antiviral immunity. We identified and determined the frequency of EBV-specific T cells in the peripheral blood of pediatric transplant recipients. METHODS: HLA-B*0801 and HLA-A*0201 tetramers folded with immunodominant EBV peptides were used to detect EBV-specific CD8+ T cells by flow cytometry in peripheral blood mononuclear cells from 24 pediatric liver and kidney transplant recipients. The expression of CD38 and CD45RO on EBV-specific, tetramer-binding cells was also examined in a subset of patients by immunofluorescent staining and flow cytometry. RESULTS: Tetramer-binding CD8+ T cells were identified in 21 of 24 transplant recipients. EBV-specific CD8+ T cells were detected as early as 4 weeks after transplant in EBV seronegative patients receiving an organ from an EBV seropositive donor. The frequencies (expressed as a percentage of the CD8+ T cells) of the tetramer-binding cells were HLA-B8-RAKFKQLL (BZLF1 lytic antigen peptide) tetramer, range=0.96 to 3.94%; HLA-B8-FLRGRAYGL (EBNA3A latent antigen peptide) tetramer, range=0.03 to 0.59%; and HLA-A2-GLCTLVAML (BMLF1 lytic antigen peptide) tetramer, range=0.06 to 0.76%. The majority of tetramer reactive cells displayed an activated/memory phenotype. CONCLUSIONS: Pediatric transplant recipients receiving immunosuppression can generate EBV-specific CD8+ T cells. Phenotypic and functional analysis of tetramer cells may prove useful in defining and monitoring EBV infection in the posttransplant patient.

The impact of severe respiratory syncytial virus on the child, caregiver, and family during hospitalization and recovery.

OBJECTIVE: To quantify the magnitude of child, caregiver, and family distress associated with hospitalization for severe respiratory syncytial virus (RSV) and the posthospitalization recovery period. DESIGN: A prospective study of 46 RSV-hospitalized infants and children < or =30 months of age with a history of prematurity (gestational age of < or =35 weeks) and 45 age-matched control subjects was performed. RSV group data were gathered during hospitalization and on days 4, 14, 21, and 60 after discharge; control group data were collected at the end of the RSV season and 60 days thereafter. MAIN OUTCOME MEASURES: RSV severity; caregiver's rating of the child's health (100-point rating) and functional status (Functional Status IIR); caregiver health, stress (7-point rating), and anxiety (Spielberger State Anxiety Inventory); and family health and functioning (Family Adaptability and Cohesion Evaluation Scale II) were recorded. RESULTS: The mean age of the sample was 10.2 months; 51% of the subjects were male. The average duration of hospital stay for the RSV group was 5.8 +/- 8 days. Most patients received supplemental oxygen (76%) and were monitored for apnea (60%). The mean age of the caregivers (93% mothers) was 29 years. During hospitalization, the RSV-infected patients' health and functional status were significantly poorer than those of control subjects. Caregivers of RSV-infected children reported more stress, greater anxiety, poorer health, and poorer family health and functioning. As long as 60 days after discharge, caregivers of RSV-infected children reported the children's health as significantly poorer and were personally more anxious, compared with control subjects. CONCLUSIONS: RSV-related hospitalization creates significant distress for infants and children, caregivers, and families, with some effects extending as long as 60 days after discharge.

Clinical practice guidelines for the maintenance of patient physical safety in the intensive care unit: use of restraining therapies--American College of Critical Care Medicine Task Force 2001-2002.

OBJECTIVE: To develop clinical practice guidelines for the use of restraining therapies to maintain physical and psychological safety of adult and pediatric patients in the intensive care unit. PARTICIPANTS: A multidisciplinary, multispecialty task force of experts in critical care practice was convened from the membership of the American College of Critical Care Medicine (ACCM), the Society of Critical Care Medicine (SCCM), and the American Association of Critical Care Nurses (AACN). EVIDENCE: The task force members reviewed the published literature (MEDLINE articles, textbooks, etc.) and provided expert opinion from which consensus was derived. Relevant published articles were reviewed individually for validity using the Cochrane methodology (http://hiru.mcmaster.ca/cochrane/ or www.cochrane.org). CONSENSUS PROCESS: The task force met as a group and by teleconference to identify the pertinent literature and derive consensus recommendations. Consideration was given to both the weight of scientific information within the literature and expert opinion. Draft documents were composed by a task force steering committee and debated by the task force members until consensus was reached by nominal group process. The task force draft then was reviewed, assessed, and edited by the Board of Regents of the ACCM. After steering committee approval, the draft document was reviewed and approved by the SCCM Council. CONCLUSIONS: The task force developed nine recommendations with regard to the use of physical restraints and pharmacologic therapies to maintain patient safety in the intensive care unit.
