title: The relative efficacy of telephone and email reminders to elicit blood donation.
abstract: The aim of the study was to test the relative efficacy of telephone and email reminders to trigger blood donation. A sample of 3454 donors was randomized to one of three conditions: phone only (n = 1176), email only (n = 1091) and phone + email (n = 1187). There was a higher proportion of donors who registered to give blood in the phone + email condition (18·45%) compared to the other two conditions (phone: 15·73%, P < 0·05; email: 13·20%; P < 0·001); this effect was apparent only in men. The phone and email conditions did not differ significantly (P = 0·16), suggesting equivalent efficacy.
