RT Journal A1 Gabel RA T1 PAtient registries, predictive models, and optimal care JF JAMA JO JAMA YR 2009 FD December 23 VO 302 IS 24 SP 2662 OP 2662 DO 10.1001/jama.2009.1098-a UL http://dx.doi.org/10.1001/jama.2009.1098-a AB To the Editor: In their Commentary, Drs Dreyer and Garner1 extolled the virtues of real-time data from patient registries as an important supplement to data derived from clinical trials. They advocated for methodological research to increase understanding of what constitutes quality and a more directed effort to evaluate the strengths and limitations of different types of evidence. However, they did not acknowledge powerful predictive modeling tools that are available to transform real-time data into evidence defining optimal care.
