This might work... But not because astrology works, but because enough people believe in it.
If someone believes in their horoscope and says today should be a good day to be adventurous, they may use that day to take more risks, and injure themselves in the process. Or the fact that particular stars are visible during different seasons. So while Orion is visible, then there is a higher chance to get the flu.
Astrology isn't science, but it is just a bunch of data loosely correlated with results. These data correlations could be used to predict higher health care activity.
