Temporal Variability in the Sampling of Vital Sign Data Limits the Accuracy of Patient State Estimation.
Physiologic signals are typically measured continuously in the critical care unit, but only recorded at intermittent time intervals in the patient health record. Low frequency data collection may not accurately reflect the variability and complexity of these signals or the patient's clinical state. We aimed to characterize how increasing the temporal window size of observation from seconds to hours modifies the measured variability and complexity of basic vital signs. ⋯ In critically ill children, the temporal variability of physiologic signals supports higher frequency data capture, and this variability should be accounted for in models of patient state estimation.

Age-Specific Distribution of Diagnosis and Outcomes of Children Admitted to ICUs: A Population-Based Cohort Study.
Although several studies have reported outcome data on critically ill children, detailed reports by age are not available. We aimed to evaluate the age-specific estimates of trends in causes of diagnosis, procedures, and outcomes of pediatric admissions to ICUs in a national representative sample. ⋯ Admission patterns, diagnosis, management, and outcomes of pediatric patients admitted to ICUs varied by age groups. Strategies to improve critical care qualities of pediatric patients need to be based on the differences of age and may need to be targeted at specific age groups.
