The official websites of blood centers in China: A nationwide cross-sectional study

Blood collection agencies worldwide are facing ongoing and increasing medical demands for blood products.

For the 253 working official websites all the 350 blood centers in China, and the mean overall score of websites was 24.7 out of 42. 79.1% websites were rated as fair (50-75% of maximum), 5.5% as good (≥75% of maximum) and 15.4% as poor(25-50% of maximum;). Websites got very low sub-scores in information quality (mean = 3.8; range 1-8; maximum = 9) and interactive services (3.3; 0-10; 10). Higher proportions of provincial (vs. regional) blood centers and economically developed (vs. developing) blood centers had official websites (p = 0.044 and p = 0.001; respectively) with better overall quality (p
