Abstract

Excess mortality risk imparted by acute respiratory failure in children is unknown. We determined excess mortality risk associated with mechanically ventilated acute respiratory failure in pediatric sepsis. Novel ICD10-based algorithms were derived and validated to identify a surrogate for acute respiratory distress syndrome to calculate excess mortality risk. Algorithm-identified ARDS was identified with specificity of 96.7% (CI 93.0 - 98.9) and sensitivity of 70.5% (CI 44.0 - 89.7). Excess risk of mortality for ARDS was 24.4% (CI 22.9 - 26.2). Development of ARDS requiring mechanical ventilation imparts modest excess risk of mortality in septic children.

Abstract

OBJECTIVE: To conduct a process evaluation of a respiratory culture diagnostic stewardship intervention.

DESIGN: Mixed-methods study.

SETTING: Tertiary-care pediatric intensive care unit (PICU).

PARTICIPANTS: Critical care, infectious diseases, and pulmonary attending physicians and fellows; PICU nurse practitioners and hospitalist physicians; pediatric residents; and PICU nurses and respiratory therapists.

METHODS: This mixed-methods study was conducted concurrently with a diagnostic stewardship intervention to reduce the inappropriate collection of respiratory cultures in mechanically ventilated children. We quantified baseline respiratory culture utilization and indications for ordering using quantitative methods. Semistructured interviews informed by these data and the Consolidated Framework for Implementation Research (CFIR) were then performed, recorded, transcribed, and coded to identify salient themes. Finally, themes identified in these interviews were used to create a cross-sectional survey.

RESULTS: The number of cultures collected per day of service varied between attending physicians (range, 2.2-27 cultures per 100 days). In total, 14 interviews were performed, and 87 clinicians completed the survey (response rate, 47%) and 77 nurses or respiratory therapists completed the survey (response rate, 17%). Clinicians varied in their stated practices regarding culture ordering, and these differences both clustered by specialty and were associated with perceived utility of the respiratory culture. Furthermore, group "default" practices, fear, and hierarchy were drivers of culture orders. Barriers to standardization included fear of a missed diagnosis and tension between practice standardization and individual decision making.

CONCLUSIONS: We identified significant variation in utilization and perceptions of respiratory cultures as well as several key barriers to implementation of this diagnostic test stewardship intervention.

Abstract

<p><strong>OBJECTIVES: </strong>Much of the research related to pediatric acute respiratory distress syndrome has focused on inhospital mortality and interventions affecting this outcome. Limited data exist on survivors' morbidity, hospital disposition, and 1-year survival. The aim of this study was to determine new morbidity rate, discharge disposition, and 1-year mortality for survivors of pediatric acute respiratory distress syndrome.</p>

<p><strong>DESIGN: </strong>Secondary analysis of prospective cohort study.</p>

<p><strong>SETTING: </strong>Quaternary children's hospital.</p>

<p><strong>PATIENTS: </strong>Three-hundred sixteen mechanically ventilated children with pediatric acute respiratory distress syndrome (Berlin and Pediatric Acute Lung Injury Consensus Conference criteria) between July 2011 and December 2014.</p>

<p><strong>INTERVENTIONS: </strong>None.</p>

<p><strong>MEASUREMENTS AND MAIN RESULTS: </strong>We performed secondary analysis of a prospectively recruited cohort of 316 mechanically ventilated children with pediatric acute respiratory distress syndrome between July 2011, and December 2014. Preillness and hospital discharge Functional Status Scale score were determined via chart review, and factors associated with new morbidity, defined as an increase of Functional Status Scale score of 3 or more, were analyzed. Demographic variables, pediatric acute respiratory distress syndrome characteristics, and ventilator management were tested for association with development of new morbidity, discharge disposition, and 1-year mortality. Inhospital mortality of pediatric acute respiratory distress syndrome was 13.3% (42/316). Of 274 survivors to hospital discharge, new morbidity was seen in 63 patients (23%). Discharge to rehabilitation rate was 24.5% (67/274) and associated with development of new morbidity. One- and 3-year mortality of survivors was 5.5% (15 deaths) and 8% (22 deaths) and was associated with baseline Functional Status Scale, immunocompromised status, Pediatric Risk of Mortality III, and organ failures at pediatric acute respiratory distress syndrome onset, but not with pediatric acute respiratory distress syndrome severity.</p>

<p><strong>CONCLUSIONS: </strong>New morbidity was common after pediatric acute respiratory distress syndrome and appears to be intermediate phenotype between survival without morbidity and death, making it a useful metric in future interventional and outcome studies in pediatric acute respiratory distress syndrome.</p>
