Apple’s Health App, a native app on all iPhones, is a localized personal health record aggregating tracking, fitness, and health related information from a growing number of applications and devices. Since 2018 with the release of iOS 10, the Health app has been able to download data from a patient’s health-system medical records using the persons active patient portal as validation and conduit. The iOS 15.x upgrade now enables the patient to select items in the Health app to share with their physicians.  Physicians are then able to open an Apple Designed and maintained Physician Dashboard in their electronic record. This functionality opens many clinical, regulatory, financial, and management questions.

Apple’s native iPhone Health app is a personal health record enabling user to passively collect and aggregate data from an ever-expanding number of tracking apps and connected devices into one source for the user to review. Since 2018, the health app has been able to connect with healthcare systems and reference laboratories to pull in clinical information, labs, test results, and office-based measurements. The only requirement was the patient had an active portal account with the source and the healthcare system had enabled the download capability, which over a thousand had done so in the United States. User satisfaction with this capability was quite high in at least one report.

With iOS 15 and higher, people could now begin sharing select data in their Health App to share with other people and their physicians. Some feel this may be the sleeper hit of iOS 15.[2] Simultaneously, Apple released application programing interfaces (“APIs”) that enabled providers in healthcare organizations to open a Physician’s Dashboard to view the patient’s self-reported information found in the Health app. The current version includes three views of the patient: a summary of data over the last year (Figure 1); a more detailed wellness view (Figure 2); and a lab view (Figure 3).

The summary view provides a high-level view what’s happened to the patient over the last year and has tiles that contain notifications, most recent labs, historical medications, and immunizations if the connected person chooses to share those items with their physicians. The Wellness section contains notifications, activity, steps, heart rate, weight, blood pressures, sleep, and menstrual cycles. Finally, there’s a lab section that will show all labs the person has received from any healthcare system or reference lab into which they have an active, connected portal account. This information can be very useful in helping patients with their chronic conditions since most chronic conditions have a large lifestyle component and many patients with chronic conditions receive medical care from disparate healthcare systems, physicians, and reference labs dependent on their insurance plans.

Surprisingly, this capability has not been widely advertised and many patients and physicians are totally unaware of this type of connectivity. This is true even for organizations, like the one I work in, where most physicians do not even thing to look or select an item called “Self-Reported Data” when reviewing a chart in preparation for a patient visit. Every physician sees a growing number of iPhone patients are using many lifestyle and activity related apps and even wearing devices and have devices at home that track a variety of activities, record weights, blood pressures, blood sugars, and sleeping patterns that would be extremely useful in managing their patient’s chronic diseases but are often totally blind to the type of devices their patients are seen using in the exam rooms. Likewise, very few iPhone using patients are aware of the native Health app, let alone its ability to connect with their physician’s healthcare system.

Smart phones are the predominant connectivity device most patients use. This is especially true at University Health Kansas City, one of Missouri’s safety net hospitals serving both the Kansas City inner core and eastern Jackson County. A large percentage of our patients are underserved on several levels and nearly half of our patients either have no insurance or covered by Medicaid. Yet very few patients we see do not carry with them a smart phone. Seventy-six percent (67 percent) of University Health Kansas City’s active portal accounts are reached using mobile devices and 50 percent of those users are using Apple’s iPhones with the remainder using one of many types of devices running one of several Android software versions. (Figure 4)[3] We have also seen a growing number of patients wearing Apple watches that significantly enhance the data available in the Health App for sharing.

Over the last year we have introduced many patients to the Physician’s Dashboard and the sharing capabilities of the Health App. It’s not unusual for most patients to say they were neither aware of the app, nor its ability to get daily feeds from their healthcare providers. Many also were not aware this app, a native iOS app on all iPhones, could be configured to communicate with many other applications and devices they were using including fitness trackers, watches, scales, thermometers, home blood pressure monitors, and other consumer devices.  Often, when these applications were installed, the default setting was to connect with the Health app and were already populating the Health app with data. Most patients that could turn on the sharing feature of the Health app (i.e. those with active portal accounts) were pleasantly surprised at how much information they could see without having to do any further customization.

Additionally, most of the patients, even some that were using the app were not taking advantage of its ability to download a host of information from over thousands of hospitals, clinics, and labs if the user has an active patient portal that has been connected to Apple Health.  They usually express surprise and relief at not having to log into their portal accounts in order to review their most recent labs.

This lack of knowledge on both the patients and the physicians contributes to the inefficient and time-consuming interactions that are crammed into ever decreasing office visit schedules.

Over the last year most iPhone touting patients introduced to this capability have turned this feature on. For those with existing active portal accounts, this process takes just a few minutes and then enables the physician and the patient to look at a very simple dashboard that has the potential to greatly enhance the office visit experience. This has led to some very interesting anecdotes.

For example, recently, a normally healthy patient presented to the clinic complaining of vague headaches and mild disorientation and came to us for diagnosis. Fortunately, this patient had turned on sharing and had religiously worn his Apple Watch. The Physician Dashboard was brought up on the examination room computer. Immediately both the patient and physician noticed a fall notification that correlated with the onset of a headache which the patient had totally forgotten (Figure 5).

Figure 5. Fall detection

This led to a quick diagnosis of post-concussion syndrome that otherwise might have been missed. Additionally, the physician’s dashboard showed other life-style changes including a change in sleeping patterns and activity following this episode including one episode of atrial fibrillation that changed the follow-up of this patient with potential optimizations of future care.

First, accuracy and integrity. The majority of tracking apps, sleep monitors, and other sundry devices that can be connected to the Health app do not fall into any of the 3 FDA health monitoring classes with only 10 percent of monitoring equipment achieving the most stringent Class 3 approval.[4] Many consumer devices do not even attempt to obtain FDA approval yet will connect and send data to the Health app. Some of these, like wrist or finger-based blood pressure cuffs have a much larger variation in results than upper arm cuffs. The same can be said for temperature monitors, many of which are contactless. These variations are offset by the ease at which many measurements can be taken so volume of data does mitigate some errors in individual measurements.

Secondly, lack of monitoring. The Health app and Physician Dashboard is not designed to provide remote monitoring services, where there is a monitoring agency that alerts clinicians to abnormal values requiring interventions. There is no Apple provided list of patients who have enabled sharing. Even when lists of patients are created, there is no guarantee the patient will not turn off sharing. In fact, this has been the case among my own patients. I did maintain a list of patients that had at one time or another turned on sharing. I stopped maintaining this list of more than 20 patients when nearly a 3rd had already turned off sharing after a few months. Does even having access to this information at the patient level increase a physician’s liability? Are patients fully instructed and reminded this data is not being monitored? Or will they assume that since their information appears in the chart there is some type of monitoring? Should we be obtaining consent forms from patients who share their information?

Third, while Apple is known for its data privacy, this cannot be assumed for the many apps a patient may use to feed the Health app. This elevates a person’s privacy risk and has been documented for some time now.[5] Misappropriation of a person’s health data and lack of access has also been constant issue, even though the Health app may mitigate some of the person’s lack of access to their own data.[6]

Fourth, financial stability. Unlike physician-ordered Remote Patient Monitoring, physicians cannot charge for reviewing this data under most regulations. The 2021 Medicare Physician Fee Schedule expanded time-based billing for patient visits that allows time spent reviewing patient-derived information, but only on the day of the visit.[7] Unlike Remote Patient Monitoring or Chronic Condition Management, the current regulations are not clear about billing for time spent reviewing and responding to this information between encounters, even though this treasure trove of data is much more robust and comprehensive than most Remote Patient Monitoring services. Will the availability and upcoming enhancements to the Health app sharing undermine current Remote Patient Monitoring and Chronic Condition Management services that, at least for Medicare Beneficiaries, are reimbursed at financially sustainable levels?

Fifth, time. The electronic medical record used by most physicians contains an overwhelming amount of information on patients that should be reviewed and reconciled on each visit according to standard best practice recommendations. But this task, done properly, would exceed the time allocated to office visits. Even medication reconciliation can be very time-consuming and complicated, particular when the patient is being seen by multiple physicians and also consuming over-the-counter medications. Nearly 100 percent of charts contain errors; 50 percent of which are errors of omission and equal 50 percent errors of commission. (Figure 6)[8]

Correcting these errors is very time-consuming and, for the most part, can only be done with the physician and patient together. Will adding access to another whole layer of data that may open up a Pandora’s Box of new sources of error add to the inaccuracies that already exist in the record due to the lack of time to review, manage, and reconcile this data?

Physicians experience a wide scope of training that enables them to see and treat most conditions patients present. We Physicians are life-long learners and are well trained to locate and learn from the scientific literature. What we are not trained to do is extract information from our EHRs and haven’t embraced using social media “big data” to enhance our ability to answer questions our patients may have. We are even less aware of nor have been trained to utilize an ever-expanding source of information derived from apps, trackers, other wearables, and even data from the patient’s beds. The ability to do so is in the hands of patients in the Apple ecosystem but will certainly advance to all platforms and may wind up being one of the more important resources available to us. In addition to paying very close attention to patients during our exams, it is also important that we pay attention to the types of devices a patient is wearing and using. They may be one of the most potent tools in our diagnostic armament soon. However, this type of patient-controlled information has the potential to overwhelm physicians, even more than they are now and raises many concerns.

Will this wind up being a game changer providing information that can be used to educate, motivate, and instruct patients to improve their management of their health and of their chronic conditions? Or will this but tool but one more layer of complexity that winds up being flotsam in the wake of our lives?
