RESUMO
An audit of blood donation at the University Hospital of the West Indies (UHWI) was performed between January 1995 and December 1998. During these four years, 21,733 persons attended the blood collection centre and 6,711 (30.8 percent) were rejected as donors. Females accounted for 3, 054 (45.6 percent) of rejected donors while 3,647 (54.4 percent) were males. Females were rejected primarily because of low haemoglobin levels, while rejection was most frequently attributed to symptoms of the common cold and recent drug use. One hunderd and two rejected donors (1.5 percent) admitted to recent treatment of a sexually transmitted disease, and 138 (2.0 percent) presented within 16 weeks of a prior donation. Of 15,022 units donated, altruistic voluntary donations accounted for 307 (2 percent) and 53 (0.3 percent) were autologous donations. Seven hundred and four units (4.6 percent) were discarded because of positivity on initial testing for a marker of transmissible infection. Overall prevalence for markers of infection was 2.5 eprcent for HTLV-1, 0.9 percent for Hepatitis B and 0.4 percent for HIV I/II. Donations at the University Hospital of the West Indies (UHWI) collection centre contributed 15.8 percent of the national blood supply for the period under study.
