  • The rate of answer retrieval was 86% in UpToDate, 69% in First Consult, 49% in ACP PIER, and 45% in Essential Evidence Plus (p<0.001).
  • The mean time to answer retrieval was significantly faster with UpToDate.
  • UpToDate seems more comprehensive in content and also faster than the other three evidence-based textbooks. Thus, it may be considered as one of the best sources for answering clinicians' questions at the point of care.
