Product Liability Defense: Adequate Warning
Manufacturer Liability for Duty to Warn: When Does Responsibility Transfer?
Manufacturers of medical devices have a legal obligation to provide warnings about known risks, complications, and proper usage in accordance with multiple FDA regulations. These requirements require that warnings be clear, visible, and easily understood while outlining potential risks and side effects. Warnings must also be appropriate to the intended user of the medical device – whether the over-the-counter product is being used by a layperson, or if the prescription device is being administered by a healthcare provider.
Even if a patient is harmed, the medical device manufacturer may argue that the injury was not caused by the lack of warning, or the patient (or physician) did not follow provided instructions. Specifically, for prescribed medical devices, manufacturers satisfy their duty to warn by informing the prescribing physician about the device’s risks (“learned intermediary doctrine”). In the 2013 case Taylor v. Intuitive Surgical, Inc., the Washington State Supreme Court examined the extent of a medical device manufacturer’s duty to warn. The plaintiff alleged that Intuitive Surgical failed to adequately warn both the hospital and the patient about the risks associated with its surgical robot. The court held that the manufacturer’s duty to warn extended to the purchasing hospital, not directly to the patient, thereby reinforcing the learned intermediary doctrine.
Even when adequate warnings are provided to the prescribing physician or the end user, there is a reasonable expectation that these warnings will be followed. Additionally, dangers that are open and obvious may require less warning. But what is considered a “reasonable expectation”? What is considered “adequate”? What is considered “open and obvious”? These terms are subjective, making them open to interpretation, debate, and defense in a court of law.
The Role of Medical Device Quality Expert Witness Services
Having a medical device expert witness with a strong background in FDA regulations, including labeling and risk disclosures requirements, is crucial when utilizing this defense. The medical device expert witness can help a manufacturer defend against failure-to-warn claims by demonstrating that adequate labeling and warnings were applied and that the organization meets ISO 13485 requirements for quality management of medical devices.
Specifically, the medical device expert witness can:
- Conduct a comparative analysis of the manufacturer’s warnings versus industry standards to prove they were efficient.
- Review warnings, labels, instructions for use, and other materials against the organization’s risk management file.
- Review the manufacturer’s risk management file to ensure elements of ISO 14971 (the international standard for risk management in medical devices) have been appropriately applied.
- Provide post-market surveillance analysis such as complaints, adverse event reports, advisory and safety notices.
Looking Ahead: The Future of Medical Device Litigation
By leveraging regulatory compliance, risk management practices, and industry standards, a medical device expert witness can help manufacturers prove that they provided adequate warnings and fulfilled their legal obligations, ultimately strengthening their defense against failure-to-warn claims. Enlisting an independent medical device quality systems expert to help build your case could be key to winning and demonstrating that the manufacturer is not liable.
