Comparative Study
Outcomes before and after implementation of a pediatric rapid-response extracorporeal membrane oxygenation program.
Rapid-response extracorporeal membrane oxygenation (RR-ECMO) has been implemented at select centers to expedite cannulation for patients placed on ECMO during extracorporeal cardiopulmonary resuscitation (ECPR). In 2008, we established such a program and used it for all pediatric venoarterial ECMO initiations. This study was designed to compare outcomes before and after program implementation. ⋯ Implementation of a pediatric RR-ECMO program for venoarterial ECMO initiation was associated with reduced neurologic complications but not improved survival during the first 3 years of program implementation. These data suggest that development of a coordinated system for rapid ECMO deployment may benefit both ECPR and non-ECPR patients, but further efforts are required to improve survival.

Results with selective preoperative lumbar drain placement for thoracic endovascular aortic repair.
The optimal use of lumbar cerebrospinal fluid drainage for the prevention of spinal cord ischemia (SCI) with thoracic endovascular aortic repair (TEVAR) remains unclear. Here, we report our experience with selective preoperative lumbar drain placement with TEVAR. ⋯ Restricted use of preoperative lumbar drains for patients at high-risk of SCI undergoing TEVAR appears safe and leads to low rates of SCI in nondrained patients. However, the utility of preoperative lumbar drains in preventing SCI with TEVAR remains questionable and should be weighed against the risk of drain complications.

Analyzing "failure to rescue": is this an opportunity for outcome improvement in cardiac surgery?
In the setting of a statewide quality collaborative approach to the review of cardiac surgical mortalities in intensive care units (ICUs), variations in complication-related outcomes became apparent. Utilizing "failure to rescue" methodology (FTR; the probability of death after a complication), we compared FTR rates after adult cardiac surgery in low, medium, and high mortality centers from a voluntary, 33-center quality collaborative. ⋯ Low mortality hospitals have superior ability to rescue patients from complications after cardiac surgery procedures. Outcomes review incorporating a collaborative multi-hospital approach can provide an ideal opportunity to review processes that anticipate and manage complications in the ICU and help recognize and share "differentiators" in care.

Comparative Study
Heterogeneity of lung volume reduction surgery outcomes in patients selected by use of evidence-based criteria.
Despite its benefit, lung volume reduction surgery (LVRS) is underused, partially because of the heterogeneous responses and lack of recent outcomes data. ⋯ There were durable improvements in FEV1 and exercise capacity in patients meeting the National Emphysema Treatment Trial criteria. Survival was comparable to that in similar patients from the National Emphysema Treatment Trial; response rates were higher in our cohort for FEV1 and 6-MWD. Those with lower 6-MWD, more emphysema, and more hyperinflation at baseline were most likely to respond to LVRS. Those with lowest exercise capacity at baseline may have a higher risk of death after LVRS.

Comparative Study
The Joint Council on Thoracic Surgery Education coronary artery assessment tool has high interrater reliability.
Barriers to incorporation of simulation in cardiothoracic surgery training include lack of standardized, validated objective assessment tools. Our aim was to measure interrater reliability and internal consistency reliability of a coronary anastomosis assessment tool created by the Joint Council on Thoracic Surgery Education. ⋯ Even without instruction on the assessment tool, experienced surgeons achieved high interrater reliability. Future resident training and evaluation may benefit from utilization of this tool for formative feedback in the simulated and operative environments. However, summative assessment in the operative setting will require further standardization and anchoring.
