Congenital diaphragmatic hernia: Observed/expected lung-to-head ratio as a predictor of long-term morbidity.

AIM: The aim of this study was to investigate the association of observed/expected (O/E) lung-to-head ratio (LHR) with long-term morbidity for isolated fetal congenital diaphragmatic hernia (CDH) patients in a single institution. METHODS: We performed a retrospective study of prenatally diagnosed CDH from 18 to 38weeks of gestation (01/2002-04/2010). Two cohorts of O/E LHR were defined (22.6-45%, 45.1-78.3%) based upon previous studies. Survivors with at least 1-year follow-up of prospectively collected long-term morbidity assessments were included. RESULTS: O/E LHR was available in 43 survivors (median 40%, range 22.8-78.3%). Follow-up data were available in 41 survivors (M:F=24:17, left CDH=39/41). Median follow-up was 6.5years (1-11years). Height/weight trajectories were similar between the two cohorts, with the majority below the 50th centile. There were no differences between the two cohorts by age 3years for Bayley scales (developmental domains) and/or REEL-3 (language development). In addition, V/Q scans in the two cohorts demonstrated similar degrees of mismatch (mean delta V/Q=35.4 versus 31.3). CONCLUSIONS: In fetuses with isolated CDH, a reduction in O/E LHR does not predict a worse outcome in long-term follow-up. There is no association between a lower O/E LHR and a reduction in REEL-3 or Bayley score nor V/Q mismatch.

The development and implementation of an inter-professional simulation based pediatric acute care curriculum for ward health care providers.

An interprofessional, simulation based, acute care course for ward health care providers was developed and implemented with the objectives of teaching identification of deteriorating patients, practicing crisis resource management and basic life support skills, and using the SBAR (Situation Background Assessment Recommendation) communication tool. Thirty-eight physicians and 51 nurses attended the four separate courses. Nine questions on a 5-point Likert scale and two open-ended questions revealed that over 95% of respondents strongly agreed/agreed that facilitators encouraged active participation, lectures were presented in an interesting manner, and that simulations were useful for practical skills and for practicing communication. Open-ended questions revealed that participants felt more confident, understood the importance of communication, roles, teamwork and valued the day. Based on this evaluation, the program was regarded as feasible and acceptable to all health care providers.

Implementation of a multicenter rapid response system in pediatric academic hospitals is effective.

OBJECTIVES: This is the first large multicenter study to examine the effectiveness of a pediatric rapid response system (PRRS). The primary objective was to determine the effect of a PRRS using a physician-led team on the rate of actual cardiopulmonary arrests, defined as an event requiring chest compressions, epinephrine, or positive pressure ventilation. The secondary objectives were to determine the effect of PRRSs on the rate of PICU readmission within 48 hours of discharge and PICU mortality after readmission and urgent PICU admission. METHODS: A PRRS was developed, implemented, and evaluated in a standardized manner across 4 pediatric academic centers in Ontario, Canada. The team responded to activations for inpatients and followed patients discharged from the PICU for 48 hours. A 2-year, prospective, observational study was conducted after implementation, and outcomes were compared with data collected 2 years before implementation. RESULTS: After PRRS implementation, there were 55 963 hospital admissions and a team activation rate of 44 per 1000 hospital admissions. There were 7302 patients followed after PICU discharge. Implementation of the PRRS was not associated with a reduction in the rate of actual cardiopulmonary arrests (1.9 vs 1.8 per 1000 hospital admissions; P=.68) or PICU mortality after urgent admission (1.3 vs 1.1 per 1000 hospital admissions; P=.25). There was a reduction in the PICU mortality rate after readmission (0.3 vs 0.1 death per 1000 hospital admissions; P=.05). CONCLUSION: The standardized implementation of a multicenter PRRS was associated with a decrease in the rate of PICU mortality after readmission but not actual cardiopulmonary arrests.

Congenital diaphragmatic hernia: lung-to-head ratio and lung volume for prediction of outcome.

OBJECTIVE: The purpose of this study was to evaluate observed/expected (O/E) lung-to-head ratio (LHR) by ultrasound (US) and total fetal lung volume (TFLV) by magnetic resonance imaging as neonatal outcome predictors in isolated fetal congenital diaphragmatic hernia (CDH). STUDY DESIGN: We conducted a retrospective study of 72 fetuses with isolated CDH, in whom O/E LHR and TFLV were evaluated as survival predictors. RESULTS: O/E LHR on US and O/E TFLV by magnetic resonance imaging were significantly lower in newborn infants with isolated CDH who died compared with survivors (30.3 ± 8.3 vs 44.2 ± 14.2; P < .0001 for O/E LHR; 21.9 ± 6.3 vs 41.5 ± 17.6; P = .001 for O/E TFLV). Area under receiver-operator characteristics curve for survival for O/E LHR was 0.80 (95% confidence interval, 0.70-0.90). On multivariate analysis, O/E LHR predicted survival, whereas hernia side and first neonatal pH did not. For each unit increase in O/E LHR, mortality odds decreased by 11% (95% confidence interval, 4-17%). CONCLUSION: In fetuses with isolated CDH, O/E LHR (US) independently predicts survival and may predict severity, allowing management to be optimized.
