Recipient clinical risk factors predominate in possible transfusion-related acute lung injury.

Background: Possible transfusion-related acute lung injury (pTRALI) cases by definition have a clear temporal relationship to an alternative recipient risk factor for acute respiratory distress syndrome (ARDS). We questioned whether transfusion factors are important for the development of pTRALI.

Study Design And Methods: In this nested case-control study, we prospectively identified 145 consecutive patients with pTRALI and randomly selected 163 transfused controls over a 4-year period at the University of California at San Francisco and the Mayo Clinic (Rochester, Minnesota).

A cross-sectional pilot study of blood utilization in 27 hospitals in Northern California.

Objectives: To gather benchmarking data on blood utilization so as to inform blood management strategies at regional hospitals.

Methods: We conducted a cross-sectional pilot study of 40 regional hospitals in Northern California using a paper-based survey designed to capture blood component utilization and transfusion management practices. The data were analyzed based on size and complexity of the respondent hospitals.

Prospective study on the clinical course and outcomes in transfusion-related acute lung injury*.

Objective: Transfusion-related acute lung injury is the leading cause of transfusion-related mortality. A prospective study using electronic surveillance was conducted at two academic medical centers in the United States with the objective to define the clinical course and outcomes in transfusion-related acute lung injury cases.

Design: Prospective case study with controls.

Cancer Incidence and Mortality in a Cohort of US Blood Donors: A 20-Year Study.

Blood donors are considered one of the healthiest populations. This study describes the epidemiology of cancer in a cohort of blood donors up to 20 years after blood donation. Records from donors who participated in the Retroviral Epidemiology Donor Study (REDS, 1991-2002) at Blood Centers of the Pacific (BCP), San Francisco, were linked to the California Cancer Registry (CCR, 1991-2010).

Transfusion-related acute lung injury: incidence and risk factors.

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality. To determine TRALI incidence by prospective, active surveillance and to identify risk factors by a case-control study, 2 academic medical centers enrolled 89 cases and 164 transfused controls. Recipient risk factors identified by multivariate analysis were higher IL-8 levels, liver surgery, chronic alcohol abuse, shock, higher peak airway pressure while being mechanically ventilated, current smoking, and positive fluid balance.
