Here’s a guest post by Dr. Henry Feldman from BIDMC’s Division of Clinical Informatics:
I am writing this from the Apple Worldwide Developer Conference (WWDC) today here in San Francisco, where I got to substitute for John Halamka at the Keynote (now I keep having urges to raise Alpacas); John missed the most amazing seats [front row center!]. There were many, many, many (I can not recall a set of software announcements of this scale from Apple) new technologies that were announced, demoed and discussed, but I will limit this entry to a few technologies that have implications for healthcare.
If you remember the state of digital music, prior to the introduction of the iPod and iTunes music store, that is where I feel the current state of the healthcare app industry is at; there is no common infrastructure between any of the offerings, and consumers have been somewhat ambivalent towards them as everything is a data island; switching apps causes data loss and is not a pleasant experience for patients. Amazingly there are 40,000+ apps on the App store at Apple alone, showing huge demand from users, but probably a handful can talk to each other in a meaningful way; this is both on the consumer and professional side of healthcare.
Individual vendors such as Withings have made impressive strides towards data consolidation on the platform, but these are not baked into the OS, so will always have a lower adoption rate. If we take the music industry example further, Apple entering a market with a full push of an ecosystem at their scale, legitimizes the technology in ways that other vendors simply can’t match. In their introduction, Apple introduced 2 healthcare specific items, the Health App and HealthKit Framework.
The Health app is a central data repository on your phone that any HealthKit enabled app can deposit data into or read data from, under user control; it also serves as a display dashboard for the user of this data repository if they don’t want to use the source app. This will allow patients to aggregate their fitness and health data from a myriad of sensors (e.g. FitBit) and sources (say a PHR app) into a single place.
They showed using this as a gateway to broker between health goals, such as blood pressure control, set up by a physician on the Mayo Clinic’s EHR and then tying that back to the patient via the PHR app/Health App linkage. Since the patient can push data back once they grant permission to an app, you can imagine as a physician who is titrating blood pressure medications in the home, getting objective data from the patient electronically (the last mile problem). Engaging our patients is both our sworn duty as physicians and over time as we learn to use these tools effectively, will help us help our patients to be more self sufficient; as our mentor Warner Slack always says “the least utilized resource in the healthcare system is the patient!”
HealthKit is to me in some …read more
