OpenFDA is releasing information on medical devices that could spur innovation and advance scientific research.

OpenFDA’s Application Programming Interface (API) expands on the previous openFDA resources concerning medical device-related adverse events and recalls by incorporating information from the medical device product life cycle. This includes current data on device classification (6,000 records), 24,000 registrations of device companies and establishments, and the companies’ listings of more than 100,000 devices.

OpenFDA is a project that provides easy access to the many large, important, health data sets collected by FDA. Data since 1976 on 30,000 device premarket approvals (PMAs) and approval supplements, and 141,000 device clearances through premarket notifications (510(k)s) and granted de novo requests are now available on openFDA. Additionally, more details about device recalls (9,500 records going back to 2002) and adverse event reports (4.2 million records since 1991) were added. Although this information has been available in our public databases for many years, now developers can more easily access and use the data.

The flexible openFDA interface works well even when greater demands are made on it and is designed on a common platform so developers can harmonize and integrate data from various sources and build their own applications. For example, developers could develop a smartphone app to search all the recalls associated with a particular type of device or find all companies that manufacture certain types of devices.

However, there are some important safeguards to the data released. For instance, the information doesn’t contain anything that potentially could be used to identify individuals or reveal confidential commercial information.

Everything available in these datasets should be understood in the appropriate context. FDA has harmonized the data, but there may be instances when a query does not return a full and complete result. For example, if the name of a manufacturer is listed with different spellings, some variations may not be captured in the result.

Some datasets are snapshots in time. The 510(k) dataset, for instance, shows who submitted the 510(k), the device name, and other information at the time of clearance. Moreover, the types of information that FDA has collected has changed over the years, which can make it difficult to look at data over time. Also, the data may not have enough information to establish cause and effect, incidence, or prevalence.

By design, openFDA is a research and development project that draws on community involvement. We are active in the openFDA communities on GitHub and StackExchange, and encourage researchers, scientists, and developers to participate in those communities. This API is the latest in a series of openFDA releases that has made publicly available data easier to access. FDA believes that you can use these tools to create innovative products that could help protect and promote public health. In fact, over the last year, there have been dozens of tools created using openFDA resources. We hope these enhanced device data will be put to similar advantageous use. Together, we can make openFDA an even more useful and powerful resource for all.

Gottlieb wants to fix clinical trials before departing FDA
The FDA has issued new draft guidance to protect human subjects of clinical trials and the data these trials generate. The draft guidance on using a risk-based approach to conducting clinical trials is one of a handful of guidances promulgated by the agency since FDA commissioner Dr. Scott Gottlieb announced his upcoming departure. In a… […]
Toray touts polymer for regenerative medicine
Toray Industries (Tokyo) recently announced that it has created a novel bioabsorbable polymer with skin-like flexibility. Proprietary functional polymer design technology allows the polymer to recover its original shape even after being stretched 10 times the original length, the company explained in a March 14 announcement. Toray also has identified a way to improve the… […]
Thornhill Medical’s ‘simple’ device may save lives
Thornhill Medical’s device to help patients suffering from carbon monoxide poisoning has won de novo clearance from the FDA. Carbon monoxide poisoning occurs when carbon monoxide attaches to the hemoglobin in the blood exactly where oxygen is supposed to attach, reducing the amount of oxygen carried to the brain and other tissues. Toronto-based Thornhill Medical’s… […]
Theranos whistleblower Tyler Shultz to participate in keynote interview at DeviceTalks Boston
At DeviceTalks Boston, Tyler Shultz will give attendees an inside look at Theranos and how he was able to sound the alarm after he realized the company was falling apart. DeviceTalks is excited to announce that Tyler Shultz will be the closing keynote speaker at DeviceTalks Boston. Shultz will take attendees behind the story that everyone… […]
Study shows catheter ablation for Afib significantly boosts quality of life
Patients who had catheter ablation for atrial fibrillation (Afib) had fewer symptoms, a significant long-term improvement in quality of life and fewer recurrences and hospitalizations than those who received drug therapy alone, according to a government-funded study. The same study showed that catheter ablation appeared no more effective than drugs in preventing strokes, deaths, and… […]
Medical device cybersecurity: It’s time to get real
Medical device makers, regulators and healthcare delivery organizations are increasingly working together to strengthen cybersecurity. But are they doing enough? Almost no one in the medtech industry disputes the vulnerability posed by cyberattacks. How to go about boosting security is another matter – one on which those stakeholders have recently stepped up their collaboration. One… […]
Can a lifetime guarantee boost value-based care?
Swiss orthopedics company Medacta International and Geisinger Health System have said they will pilot a lifetime guarantee program for knee replacement surgeries. The program will cover full costs for screened Geisinger Health Plan members who receive knee replacement surgery while also ensuring reimbursement for any associated future care the patients may incur throughout their lifetimes.… […]
