FDA Posts 483 of iRhythm’s CA Facility
A just-posted, four-item Form FDA-483 provides more detail on medical device reporting (MDR) and other violations cited in a 2022 inspection of iRhythm’s Cypress, CA manufacturing facility that led to a recent Warning Letter on its ZIO AT arrhythmia monitoring system. The inspection form cited the firm for 28 complaints about patient episodes that should have been reported to their physicians but were blocked due to the device reaching its maximum threshold for report transmission.
FDA’s inspection also reviewed 39 patient tickets where physician-reportable episodes occurred, but report transmission did not process because the patient registration was incomplete. During the inspection, the tickets were still opened and the records did not show follow up on the patient status to determine the impact of any delayed physician notifications, according to the 483. Additionally, the firm was cited for failing to submit an MDR to FDA no later than 30 calendar days after the day that iRhythm received or otherwise became aware of information that reasonably suggested that its device a may have caused or contributed to a death or serious injury.
