TY - JOUR T1 - ECmo centers and mortality from influenza a(h1n1)—reply AU - Peek GJ, Rowan KM Y1 - 2012/02/01 N1 - 10.1001/jama.2012.58 JO - JAMA SP - 454 EP - 455 VL - 307 IS - 5 N2 - In the absence of these definitive respiratory values during treatment for non–ECMO-referred patients, but with a view to exploring the hypothesis that Haeck et al outline, we conducted 2 sensitivity analyses limiting comparison of the ECMO-referred patients to non–ECMO-referred patients treated in critical care units either with a higher volume of ventilated patients or with a lower standardized mortality ratio—characteristics associated with better outcomes for ventilated patients and for all patients, respectively. Our base-case results were robust to these sensitivity analyses. SN - 0098-7484 M3 - doi: 10.1001/jama.2012.58 UR - http://dx.doi.org/10.1001/jama.2012.58 ER -
