  • 3. According to one of the recent study published
    in an International report, the cost of medical
    malpractice in the United States is USD 55.6
    billion a year, which is approximately 2.4
    percent of US annual health-care spending. An
    earlier research report published in 2011, in the
    New England Journal of Medicine revealed that,
    during the period 1991 to 2005, 7.4 percent of
    all physicians licensed in the US had a
    malpractice claim. These staggering numbers not
    only contribute to the high cost of health care,
    but the size of successful malpractice claims
    also contributes to high premiums for medical
    malpractice insurance. The table below contains a
    sample of data set of claim payments made in a
    years time and other information about the
