According to new research from The Doctors Company, the nation’s largest physician-owned medical malpractice insurer and part of TDC Group, social inflation accounted for between $2.4 and $3.5 billion, or 8 to 11 percent, of all medical malpractice losses incurred by physician-focused insurers in the decade ending in 2021.

Moore Actuarial Consulting, LLC was hired by The Doctors Company to conduct the study, “Medical Malpractice Claims-Made Social Inflation and Loss Development Report,” in order to determine the level of social inflation in the U.S. physician medical malpractice claims-made market. When an insurer’s average claim amount grows faster than the overall inflation rate, this is referred to as social inflation. When this occurs, insurers are forced to raise rates and/or reduce coverage to keep up.

“As an organization led by physicians, we know that commissioning important industry research is part of our mission to serve those who provide care. The study we are releasing today shows that physicians are affected by social inflation,” said Robert E. White, Jr., President of TDC Group. “Our research shows that the pace of settlements larger than $1 million has accelerated, and large settlements are a significant driver of social inflation. It is a reason malpractice premiums are rising for many physicians.” Independently practicing advanced practice clinicians, such as some nurse practitioners, may also be affected.

The study examined loss development factors (LDFs), a standard actuarial metric, across more than a decade for physician-focused medical malpractice insurers. In theory, these factors should change little except for random variation. Instead, they have been rising. The study uses the increase in LDFs to estimate the impact of social inflation. In addition, the study examines data from the National Practitioner Data Bank (NPDB), a federal dataset that collects information on, among other things, malpractice payments.
