Development of Persistent Respiratory Morbidity in Previously Healthy Children After Acute Respiratory Failure.

OBJECTIVES: Acute respiratory failure is a common reason for admission to PICUs. Short- and long-term effects on pulmonary health in previously healthy children after acute respiratory failure requiring mechanical ventilation are unknown. The aim was to determine if clinical course or characteristics of mechanical ventilation predict persistent respiratory morbidity at follow-up. DESIGN: Prospective cohort study with follow-up questionnaires at 6 and 12 months. SETTING: Ten U.S. PICUs. PATIENTS: Two-hundred fifty-five children were included in analysis after exclusion for underlying chronic disease or incomplete data. One-hundred fifty-eight and 130 children had follow-up data at 6 and 12 months, respectively. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Pulmonary dysfunction at discharge a priori defined as one of: mechanical ventilation, supplemental oxygen, bronchodilators or steroids at 28 days or discharge. Persistent respiratory morbidity a priori defined as a respiratory PedsQL, a pediatric quality of life measure, greater than or equal to 5 or asthma diagnosis, bronchodilator or inhaled steroids, or unscheduled clinical evaluation for respiratory symptoms. Multivariate backward stepwise regression using Akaike information criterion minimization determined independent predictors of these outcomes. Pulmonary dysfunction at discharge was present in 34% of patients. Positive bacterial respiratory culture predicted pulmonary dysfunction at discharge (odds ratio, 4.38; 95% CI, 1.66-11.56). At 6- and 12-month follow-up 42% and 44% of responders, respectively, had persistent respiratory morbidity. Pulmonary dysfunction at discharge was associated with persistent respiratory morbidity at 6 months, and persistent respiratory morbidity at 6 months was strongly predictive of 12-month persistent respiratory morbidity (odds ratio, 18.58; 95% CI, 6.68-52.67). Positive bacterial respiratory culture remained predictive of persistent respiratory morbidity in patients at both follow-up points. CONCLUSIONS: Persistent respiratory morbidity develops in up to potentially 44% of previously healthy children less than or equal to 24 months old at follow-up after acute respiratory failure requiring mechanical ventilation. This is the first study, to our knowledge, to suggest a prevalence of persistent respiratory morbidity and the association between positive bacterial respiratory culture and pulmonary morbidity in a population of only previously healthy children with acute respiratory failure.

Exploring the scope of post-intensive care syndrome therapy and care: engagement of non-critical care providers and survivors in a second stakeholders meeting.

BACKGROUND: Increasing numbers of survivors of critical illness are at risk for physical, cognitive, and/or mental health impairments that may persist for months or years after hospital discharge. The post-intensive care syndrome framework encompassing these multidimensional morbidities was developed at the 2010 Society of Critical Care Medicine conference on improving long-term outcomes after critical illness for survivors and their families. OBJECTIVES: To report on engagement with non-critical care providers and survivors during the 2012 Society of Critical Care Medicine post-intensive care syndrome stakeholder conference. Task groups developed strategies and resources required for raising awareness and education, understanding and addressing barriers to clinical practice, and identifying research gaps and resources, aimed at improving patient and family outcomes. PARTICIPANTS: Representatives from 21 professional associations or health systems involved in the provision of both critical care and rehabilitation of ICU survivors in the United States and ICU survivors and family members. DESIGN: Stakeholder consensus meeting. Researchers presented summaries on morbidities for survivors and their families, whereas survivors presented their own experiences. MEETING OUTCOMES: Future steps were planned regarding 1) recognizing, preventing, and treating post-intensive care syndrome, 2) building strategies for institutional capacity to support and partner with survivors and families, and 3) understanding and addressing barriers to practice. There was recognition of the need for systematic and frequent assessment for post-intensive care syndrome across the continuum of care, including explicit "functional reconciliation" (assessing gaps between a patient's pre-ICU and current functional ability at all intra- and interinstitutional transitions of care). Future post-intensive care syndrome research topic areas were identified across the continuum of recovery: characterization of at-risk patients (including recognizing risk factors, mechanisms of injury, and optimal screening instruments), prevention and treatment interventions, and outcomes research for patients and families. CONCLUSIONS: Raising awareness of post-intensive care syndrome for the public and both critical care and non-critical care clinicians will inform a more coordinated approach to treatment and support during recovery after critical illness. Continued conceptual development and engagement with additional stakeholders is required.

Development of an observational tool on computer use during rounds.

We present an observational tool to capture computer usage patterns during rounds to inform designs of information and communication technology to support clinical discourse during rounds. The tool captures choreography and logistics of information exchanges supported by clinical information systems during rounds. We developed the tool as part of an ongoing video-recording study of communication to under-stand how, when, and why computers are used during multidisciplinary clinical rounds.

The value of autopsy in pediatric cardiology and cardiovascular surgery.

Autopsy has been considered extremely helpful in determining the accuracy of the premorbid diagnosis. With recent advances in diagnostic imaging, the value of the autopsy has been called into question. The aim of this study was to assess the value of the pediatric autopsy in the current era of advanced diagnostic technology and sophisticated surgical intervention for congenital heart disease (CHD) and also to determine the autopsy's potential impact on clinical management. We compared the data from the postmortem examination of 29 children with CHD with the data obtained before death and evaluated for the accuracy of the diagnosis of the cardiac anatomy as well as the cause of death. The diagnosis of the anatomy was confirmed in 13 cases (45%), additional cardiovascular abnormalities with potential clinical impact were found in 11 cases (38%), and additional abnormalities without clinical impact were found in 5 cases (17%). The cause of death was confirmed in 15 cases (52%), determined by autopsy in 12 cases (41%), and uncertain in 2 cases (7%). We conclude that the pediatric autopsy continues to provide clinically relevant information with a potential impact on patient management and to reveal unexpected causes of death in a significant proportion of patients with CHD.

Influenza B infection associated with encephalitis: treatment with oseltamivir.

Encephalitis associated with acute influenza infection is unusual in nonepidemic years. A case of a 10-year-old child with influenza B encephalitis and profound weakness who was treated with oseltamivir is presented. This case illustrates several of the unusual findings associated with influenza infections and the result of treatment of influenza B encephalitis with oseltamivir.
