BACKGROUND The potential effectiveness of various donation incentive programs may vary by demographics, first-time or repeat status, and collection site. STUDY DESIGN AND METHODS Attitudes toward future incentives were obtained from a 1998 anonymous survey sent to 92,581 US blood donors. Responses (encouraged, discouraged, no difference) to incentives(More)
BACKGROUND Evidence indicates that donor identity is an important predictor of donation behavior; however, prior studies have relied on diverse, unidimensional measures with limited psychometric support. The goals of this study were to examine the application of self-determination theory to blood donor motivations and to develop and validate a related(More)
We describe a 54-year-old spleen-intact man with transfusion-associated Babesia microti infection after a heart transplant. Adult respiratory distress syndrome developed in the patient, and he required mechanical ventilation. Our experiences with this patient suggest that babesiosis should be considered in the differential diagnosis of transplant patients(More)
BACKGROUND To prevent donor loss and improve retention, it is important to understand the major deterrents to blood donation and to identify factors that can be effectively addressed by blood centers. STUDY DESIGN AND METHODS A 30-item self-administered questionnaire was completed in 2003 by 1705 first-time and 2437 repeat US donors who had not donated in(More)
BACKGROUND Genetic variations of human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B virus (HBV) can affect diagnostic assays and therapeutic interventions. Recent changes in prevalence of subtypes/genotypes and drug/immune-escape variants were characterized by comparing recently infected vs more remotely infected blood donors. (More)
BACKGROUND Computer-assisted self-interviewing (CASI) has been shown to promote disclosures of sensitive information. Using CASI to screen blood-donor candidates might encourage reports of deferrable risks without discouraging eligible donors. STUDY DESIGN AND METHODS In 1998, an anonymous mail survey was sent to donors from eight blood centers. The(More)
BACKGROUND Blood donation can be described as a prosocial behavior, and donors often cite prosocial reasons such as altruism, empathy, or social responsibility for their willingness to donate. Previous studies have not quantitatively evaluated these characteristics in donors or examined how they relate to donation frequency. STUDY DESIGN AND METHODS As(More)
BACKGROUND Chagas disease is a parasitic infection by Trypanosoma cruzi, typically transmitted via infected triatomine bug fecal contamination of bite sites. Other routes of infection include congenital, oral, organ transplantation, and blood product transmission. STUDY DESIGN AND METHODS From 2007 until 2011, New York Blood Center screened donations for(More)
BACKGROUND Men who have had sex with men (MSM) since 1977 are permanently deferred from donating blood. Excluding only men who engaged in male-to-male sex within either the prior 12 months or 5 years has been proposed. Little is known about infectious disease risks of MSM who donate blood. STUDY DESIGN AND METHODS Weighted analyses of data from an(More)
BACKGROUND Differences in motivating factors that contribute to the decision to donate blood between infected and uninfected donors may help to identify areas for improving donor education. STUDY DESIGN AND METHODS As part of a risk factor study, confirmed-positive donors (cases) based on serology-only (human T-lymphotropic virus [HTLV]) or serology and(More)
