Investments in the Veterans Health Information Systems and Technology Architecture (VistA) between 2001 and 2007 led to fewer unnecessary or redundant tests and better care, which added up to $3.09 billion in overall net benefits after investment costs, according to a study recently published in Health Affairs. Part of the reason for such results was the high adoption rate of VistA components since 2004, which was found to be nearly 100 percent. By comparison, adoption of health IT in the private sector has been lacking; among other statistics, the study points out that adoption of inpatient EHRs is at 61 percent, while CPOE use is only at 16 percent.
