简要总结
ABC PICU is a randomized clinical trial that will compare the clinical consequences of RBC storage duration in 1538 critically ill children. Laboratory and observational evidence points to serious concerns about the lack of safety and effectiveness of older RBCs, especially in more vulnerable populations. Physicians and institutions have been systematically transfusing fresh RBCs to some pediatric patients primarily because of beliefs that the use of fresh RBCs improve outcomes. Conversely, the standard practice of blood banks is to deliver the oldest RBC unit in order to decrease blood wastage. To provide much needed high quality evidence to answer the question "do RBCs of reduced storage duration improve outcomes?" The ABC PICU Trial will conduct a RCT comparing development of New or Progressive Multiple Organ Dysfunction Syndrome (NPMODS) in critically ill children transfused with either RBCs stored ≤ 7 days or standard issue RBCs (expected mean RBC storage duration of 17-21 days).

结局指标
主要结局
Number of Participants With New or Progressive Multiple Organ Dysfunction Syndrome (NPMODS)
时间窗: 28 days after randomization
The primary outcome measure of this RCT is NPMODS defined as the proportion of patients who die during the 28 days after randomization or who develop NPMODS. For patients with no organ dysfunction at randomization, New MODS is the development of ≥ 2 concurrent organ dysfunctions during the 28 days after randomization. For patients with 1 organ dysfunction at randomization, New MODS is the development of at least 1 other concurrent organ dysfunction after randomization. Patients with MODS (ie concurrent dysfunction of ≥ 2 organ systems) at randomization can develop Progressive MODS defined as development of at least 1 additional concurrent organ dysfunction at during the 28 days after randomization. All deaths will be considered Progressive MODS. NPMODS will be monitored up to 28 days or ICU discharge because it is almost never observed beyond this time in children.
