During its recent quarterly call with investors, WebMD teased a small acquisition it made last month, and MobiHealthNews found out they’ve bought TheraSim.

According to WebMD VP of Corporate Communication Michael Heinley, TheraSim offers patient simulation technology that replicates physicians’ real-world experiences in clinical decision making, and drives application of learning into clinical practice. The acquisition will allow WebMD’s Medscape to “further evolve and enhance the Medscape experience for health care professionals participating in continuing education.”

At the same time, WebMD also discussed its numbers, saying that revenues grew 12% year-over-year to hit $140.4 million and adjusted EBITDA increased by 30% to $37.9 million. The traffic to WebMD sites reached an average of 179.4 million unique users per month who generated 3.46 billion views. Those made for a 43% and 31% increase, respectively, year-over-year.

Meanwhile, WebMD’s provider-facing offering, Medscape, also saw an increase in traffic during the quarter: the site and app has 6.1 million physician sessions overall per month, making for an 11% increase year-over-year. About 625.000 registered US physicians are active on Medscape, according to the company.
