A recent report from RNCOS called the US Healthcare IT Market Analysis indicates that it may be. The report estimates that the mobile health market will have a 17 percent year-over-year growth rate between 2010 and 2011. The research firm estimates the market will be worth $2.1 billion by the end of 2011, InformationWeek reports. RNCOS expects the market to grow 22 percent from 2012 to 2014.

RNCOS sees mobile health playing a key role in "healthcare delivery, including education and awareness, remote data collection, remote monitoring, disease and epidemic outbreak tracking, and diagnostic and treatment support," according to the report.

"The buzz surrounding mobile healthcare has steadily grown during the past two years. There's no question that this area holds enormous potential in terms of improving patient care in the U.S.," the RNCOS report concludes.

We have noted in the past how difficult it is to peg a total market value on mobile health because that depends entirely on how it's defined. Around this time last year we compared the various billion dollar estimates research firms had offered up for the mobile health market, remote monitoring, and the like. What was true for each was that the estimate was in the billions of dollars.
