Objective:
To study incidence and death among previous paid blood-donated AIDS sufferers.
Methods:
A retrospective cohort study was adopted to study incidence and death of 373 previous paid blood-donated HIV sufferers and its effect factors.
Results:
Previous paid blood-donated HIV infection was serious and the infection rate in blood-donated crowd was 35.87% (373/1040); the mean incubation period of AIDS was 8.87 years (95% CI: 8.76 - 8.99, Kaplan-Meier method); the cumulative incidence of AIDS (10 years) was 92.23% (344/373), and the incidence of total sufferers was 11.64/100 person-year; the cumulative probability of survival of one-year, three-year, five-year AIDS sufferers was separately 94.48% (325/344), 85.76% (295/344) and 83.14% (286/344), median survival time was over 5 years; the anti-virotic treatment days (960.29 +/- 486.38), infection age (33.39 +/- 9.08) disease age (41.98 +/- 8.88) had significant effects on AIDS sufferers' survival time/survival rate (chi(2) = 61.355, P = 0.000; chi(2) = 6.555, P = 0.010; chi(2) = 3.969, P = 0.046).
Conclusion:
The survival time of previous paid blood-donated HIV cases was longer, and their survival rate was higher, remarkably higher than the UNAIDS' research findings.
