The assumption that enacting laws to shield doctors from malpractice suits will significantly alter how they deliver care is increasingly being questioned by recent research. Although policymakers often believe that reducing legal risks for physicians will decrease defensive medicine and, consequently, healthcare costs, emerging evidence suggests otherwise. A comprehensive study conducted by UCLA and RAND Corporation indicates that such legal reforms might not have the expected impact on medical decision-making or overall healthcare expenditures.
In this investigation, researchers focused on emergency physicians practicing in three states—Georgia, Texas, and South Carolina—that had recently heightened the legal standards for malpractice claims in emergency care to what is known as “gross negligence.” Under this stricter standard, plaintiffs are required to demonstrate that a physician consciously disregarded the need to exercise reasonable care, fully aware that their actions could cause serious injury. This is a notable shift from the more common “ordinary negligence” standard, which typically involves a failure to act with reasonable care.
The prevailing assumption has been that such reforms would provide physicians with a form of legal immunity, thereby reducing their fear of lawsuits and, consequently, the practice of ordering unnecessary tests or procedures, often referred to as defensive medicine. Defensive medicine is widely believed to contribute substantially to the billions of dollars spent annually on unnecessary healthcare services in the United States. Many health policy advocates argue that reforming malpractice laws is a crucial step toward controlling these costs.
To evaluate the effects of these reforms, the researchers analyzed data from 3.8 million Medicare patient records collected across 1,166 hospital emergency departments between 1997 and 2011. They compared the care provided before and after the enactment of the reforms in the three states against neighboring states that did not implement similar changes. The focus was on three specific indicators: the ordering of advanced imaging tests like CT scans or MRIs, the rate of patient hospitalization after emergency visits, and the total charges associated with these visits. These factors are significant because they often represent the most costly aspects of emergency care and are commonly associated with defensive practice patterns.
Surprisingly, the results revealed that the legal reforms had little to no impact on physicians’ ordering habits or hospitalization rates. For Texas and South Carolina, there was no statistically significant reduction in charges or medical interventions. Georgia experienced a modest decrease of about 3.6% in emergency room charges after the law change in 2005, but overall, the reforms did not lead to substantial cost savings or changes in clinical behavior.
Dr. Daniel Waxman, the study’s lead author and an emergency physician affiliated with UCLA’s David Geffen School of Medicine, explained, “Our findings suggest that even when the risk of legal repercussions decreases, physicians may still opt for resource-intensive care due to ingrained practices, cultural factors, or perceived patient expectations.” This indicates that the relationship between malpractice laws and defensive medicine is more complex than many policymakers assume.
The study’s conclusions challenge the narrative that legal reforms alone can significantly curb unnecessary healthcare spending. They imply that other factors—such as institutional policies, provider training, and patient-physician communication—may play more vital roles in influencing clinical decision-making.

Furthermore, understanding the broader context of healthcare reforms and policies can help shape effective strategies. For example, the concept of single-payer systems, which aim to simplify healthcare financing and reduce administrative costs, is gaining attention as an alternative approach.

Ultimately, this research underscores that legal protections, while important, are not a silver bullet for reducing healthcare costs or changing physician behavior. Instead, a multifaceted approach that addresses cultural, systemic, and educational factors may be necessary to achieve meaningful improvements in healthcare efficiency and quality.
