Abstract
BACKGROUND
At the U.S. Food and Drug Administration (FDA), the mission of the Center for Devices and Radiological Health (CDRH) is to ensure that all patients and providers have timely and continued access to safe, effective, and high-quality medical devices and safe radiation-emitting products. Although the CDRH has observed enrollment differences in some clinical trials, no systematic analysis has been conducted regarding enrollment differences in baseline demographics, to our knowledge.
METHODS
The CDRH has summarized information on study participants and their baseline demographics in public-facing documentation for all authorized medical devices that involved orthopaedic clinical studies from 1985 to 2020. Descriptive analyses and exploratory statistical testing have been conducted to investigate the reported percentages by sex and race compared with those reported in the U.S. National Census and the American Joint Replacement Registry (AJRR), respectively.
RESULTS
We identified 94 submissions and corresponding combined clinical trials from 261 original clinical study arms with 34,193 participants. Most of the submissions reported age and sex, while only 36 submissions (38.3%) reported racial demographics. Among the 88 trials providing enrollment by sex, the female enrollment percentage ranged from 22.2% to 88.7%, with a mean of 55.0%. In the submissions that reported racial data (38.3%), White and Black patients had a mean enrollment of 89.2% (range, 64.8% to 98.7%) and 6.2% (range, 0.4% to 20.7%), respectively. The enrollment for other minority groups ranged from 0% to 3.0%. These clinical trials have shown numerically lower female representation (55.0%) but higher White representation (89.2%) than what has been reported in the AJRR. The other racial groups have participated much less than their corresponding percentages in the U.S. population, but they are similarly represented in the AJRR.
CONCLUSIONS
The clinical trials supporting the FDA's authorization of orthopaedic devices had a wide range of sex and racial enrollments. It appears that female enrollment mirrors the percentage of women in the U.S. population. However, despite prior efforts, some racial groups are still underrepresented. The FDA has made a commitment to advancing health equity as part of the 2022-2025 Strategic Priorities of the CDRH. We hope that the results of this study will help health-care professionals make informed clinical decisions when using medical devices.
