With the announcement that the FDA granted 510(k) approval for the AliveCor EKG case for the iPhone 4/4s, the device became available to “licensed U.S. medical professionals and prescribed patients to record, display, store, and transfer single-channel electrocardiogram (ECG) rhythms.”
While this sounds nice, how, exactly, does one become a “prescribed patient?” Once a doctor “prescribes” such a device, what are his responsibilities? Does this obligate the physician to 24/7/365 availability for EKG interpretations? How are HIPAA-compliant tracings sent between doctor and patient? How are the tracings and medical care documented in the (electronic) medical record? What are the legal risks to the doctor if the patient transmits OTHER patient’s EKG’s to OTHER people, non-securely?
At this point, no one knows. We are entering into new, uncharted medicolegal territory.
But the legal risks for prescribing a device to a patient are, sadly, probably real, especially since the FDA has now officially sanctioned this little iPhone case as a real, “live” medical device. But I must say, I am not a legal expert in this area and would defer to others with more legal expertise to comment on these thorny issues.
This issue came up because a patient saw the device demonstrated in my office and wanted me to prescribe it for them. So I sent AliveCor’s Dr. Dave Alpert a tweet and later received this “how to” e-mail response from their support team:
Dear Dr. Fisher,
Thank you for your interest in the AliveCor Heart Monitor. I’m writing in response to your tweet to Dr. Dave (Alpert) yesterday. Below are the instructions; in addition these instructions can be found at www.alivecor.com (click on the “Buy Now” link in the upper right corner).
To obtain a monitor for your patients, please follow these steps:
1. Write a prescription for the “AliveCor Heart Monitor for iPhone 4/4S”
2. Ask your patient to go to here and submit the following:
a. The prescriber’s information – your name, address, phone number, license number and license state or NPI (National Provider Identifier)
b. A copy of the prescription (attach a scanned copy or photo)
3. Go to www.alivecor.com and click on the “Buy Now” link in the upper right to purchase the monitor
a. In the “NPI/State Medical Lic #” enter “Prescription”
NOTE: The patient’s credit card will be charged once they place their order, however we can’t process their order unless we have received their prescription.
Please know that at this time AliveCor does not provide any ECG interpretation, diagnosis or analysis of the data obtained with the monitor. Patients will be instructed to contact you, their physician, regarding any questions they may have regarding their recordings.
Please let me know if you have any questions.
It is clear AliveCor wants to provide the device and its app, but will not be responsible for the interpretation of EKG’s. That is up to the doctor and their patient how to manage the clinical expectations of this technology. While some patients could probably perform EKG interpretation basics, I would guess most don’t really understand what that wavy line means. Hence, this is where a discussion should be held with a patient BEFORE prescribing this device and the expectations defined before its use.
For me, I am happy to provide interpretations free of charge when needed as long as it is convenient and non-disruptive to my clinical responsibilities and personal life. There are only so many hours of the day and since I must value that time, cannot bill for this EKG-reading service, and have no quality control over the caliber of the recordings submitted, I consider my interpretations of tracings sent to me to be provided to the patient as a “good Samaritan” in every legal sense of the term. Patients who have clinically worrisome symptoms and need emergent analysis of their heart rhythm should seek help in an emergency department or call 911 and not expect a doctor to provide an immediate interpretation of their tracing, unless such an arrangement is defined clearly between doctor and patient before issuing the device. Expecting a doctor to make urgent clinical decisions based on this single-lead EKG app is of limited utility, in many (and maybe most) instances in my view, so patients should look at this device as a convenient adjunct to more conventional medical care. While it might come one day, the AliveCor iPhone EKG has simply has never been tested for emergency use as of the time of this writing.
So I may do a test run to see how it goes on a test basis but I can already see some legal concerns for doctors who prescribe this device. Until a clear interpretation workflow is established that can provide comprehensive coverage of interpretations paired with a well-defined and easy-to-use interface with a medical record system, patients should understand doctors’ possible hesitation to prescribing this device to a multitude of patients for personal use.
