Health Care Industry

I am looking for some information on the healtcare industry (specifically IT in healthcare) such as growth prospects, current market size, top companies etc. Just general statistics on the industry. Anyone know where I can get such information?

hmcq, look to gartnber and forrester research, there wasa lot of analysis done for Healthcare I/T when the HIPAA regulations were being outlined back in 2000, i think since then they have covered the industry fairly well.
