Importance: There is limited evidence that the use of severity of illness scores in pediatric patients can facilitate timely admission to the intensive care unit or improve patient outcomes.Objective: To determine the effect of the Bedside Paediatric Early Warning System (BedsidePEWS) on all-cause hospital mortality and late admission to the intensive care unit (ICU), cardiac arrest, and ICU resource use.Design, Setting, and Participants: A multicenter cluster randomized trial of 21 hospitals located in 7 countries (Belgium, Canada, England, Ireland, Italy, New Zealand, and the Netherlands) that provided inpatient pediatric care for infants (gestational age ≥37 weeks) to teenagers (aged ≤18 years). Participating hospitals had continuous physician staffing and subspecialized pediatric services. Patient enrollment began on February 28, 2011, and ended on June 21, 2015. Follow-up ended on July 19, 2015.Interventions: The BedsidePEWS intervention (10 hospitals) was compared with usual care (no severity of illness score; 11 hospitals).Main Outcomes and Measures: The primary outcome was all-cause hospital mortality. The secondary outcome was a significant clinical deterioration event, which was defined as a composite outcome reflecting late ICU admission. Regression analyses accounted for hospital-level clustering and baseline rates.Results: Among 144 539 patient discharges at 21 randomized hospitals, there were 559 443 patient-days and 144 539 patients (100%) completed the trial. All-cause hospital mortality was 1.93 per 1000 patient discharges at hospitals with BedsidePEWS and 1.56 per 1000 patient discharges at hospitals with usual care (adjusted between-group rate difference, 0.01 [95% CI, -0.80 to 0.81 per 1000 patient discharges]; adjusted odds ratio, 1.01 [95% CI, 0.61 to 1.69]; P = .96). Significant clinical deterioration events occurred during 0.50 per 1000 patient-days at hospitals with BedsidePEWS vs 0.84 per 1000 patient-days at hospitals with usual care (adjusted between-group rate difference, -0.34 [95% CI, -0.73 to 0.05 per 1000 patient-days]; adjusted rate ratio, 0.77 [95% CI, 0.61 to 0.97]; P = .03).Conclusions and Relevance: Implementation of the Bedside Paediatric Early Warning System compared with usual care did not significantly decrease all-cause mortality among hospitalized pediatric patients. These findings do not support the use of this system to reduce mortality.Trial Registration: clinicaltrials.gov Identifier: NCT01260831. [ABSTRACT FROM AUTHOR]

Context: The benefits of therapeutic hypothermia as a treatment for traumatic brain injury (TBI) remain unclear. Objective: To explore the effects of depth, duration, and rate of rewarming after discontinuation of hypothermia on mortality and neurologic outcome in adults after TBI. Data Sources: An electronic search of MEDLINE (OVID), EMBASE, Current Contents, the Cochrane library and a hand search of key journals were performed. Corresponding authors of identified studies were contacted for additional unpublished or ongoing clinical trials. Study Selection: All randomized controlled trials of therapeutic hypothermia for at least 24 hours vs normothermia in adults with TBI. Data Extraction: Demographic and clinical data, hypothermia interventions and cointerventions, mortality and neurologic outcomes, and methodological quality were abstracted by 2 independent reviewers. Data Synthesis: Twelve trials met eligibility criteria and were included in the analysis. We also performed subanalyses by different hypothermia interventions (ie, depth, duration, and rapidity of rewarming after hypothermia) and methodological quality. Therapeutic hypothermia was associated with a 19% reduction in the risk of death (95% confidence interval [CI], 0.69-0.96) and a 22% reduction in the risk of poor neurologic outcome (95% CI, 0.63-0.98) compared with normothermia. Hypothermia longer than 48 hours was associated with a reduction in the risks of death and of poor neurologic outcome (relative risk [RR], 0.70; 95% CI, 0.56-0.87 and RR, 0.65; 95% CI, 0.48-0.89, respectively) compared with normothermia. Hypothermia to a target temperature between 32°C and 33°C, a duration of 24 hours, and rewarming within 24 hours were all associated with reduced risks of poor neurologic outcome compared with normothermia. Assessment of methodological quality did not reveal evidence of bias. Conclusions: Therapeutic hypothermia may reduce the risks of mortality and poor neurologic outcome in... [ABSTRACT FROM AUTHOR]
