As a project manager who works in clinical research, I know how important patient recruitment is for successful clinical trials. IBM’s recent partnership with Mayo Clinic to leverage IBM Watson’s cognitive analytics abilities to match patients with the appropriate clinical trials is a potential game-changer in the research community where many trials fail due to lack of enrollment.

Clinical trials recruitment is an vital aspect of research. For you statistics nerds, you know that by having a higher "n" (population size), you will have a greater confidence level (better results). Well sometimes, clinical trials do not have the "n" that they would like for their study so need to recruit additional participants.
“Matching is such a hard and cumbersome process,” Sean Hogan, IBM vice president of healthcare told Fox News. For anyone who has worked in clinical trials recruitment, they will tell you that this is a very manual, data-driven process. I have worked first hands with principal investigator's and know that recruitment takes so many man hours that could be better served on actual research. And in worst case scenario's some research studies can fail due to not recruiting enough participants.
If IBM can leverage cognitive analytics to help automate this manual process, this will mean a higher population size for clinical trials and lead to better results. Definitely a good thing as research moves forward into the 21st century.
