The consequences of temporary deferral on future whole blood donation.

摘要: BACKGROUND: The consequences of temporary deferral are not well understood. This study sought to investigate blood donor return after expiration. STUDY DESIGN AND METHODS: A retrospective cohort analysis allogeneic whole-blood donation was conducted. All deferred donors and a random sample eligible were identified from the year 2000, with subsequent center visits through December 2005 captured. Stratified results reported as percentage returning, rates return, time return. Measures statistical association Cox regression modeling reported. RESULTS: For first-time (FT) donors, 25 percent temporarily returned during 5-year follow-up period compared 47 (p < 0.0001); for repeat 81 86 returned, respectively 0.0001). Depending on category, 14 31 FT 58 90 returned. Rates (per year) successful 0.09 index-deferred 0.28 1.0 1.45 donors.
