An Example of Bad Design: This App’s Interface for Entering Blood Pressure

Screen Shot 2014-04-14 at 7.24.01 PM

Here’s a design approach that I really, really dislike: the scrolling wheel that is often used for number entry in iOS apps:

I find that the scrolling wheel makes it very tiresome to enter numbers, and much prefer apps that offer a number pad, or another way to touch the number you need. (Or at least decrease the number at hand in sensible increments.)

You may think I’m being too picky, but I really think our ability to leverage technology will hinge in part on these apps and devices being very usable.

And that usability has to be considered for everyone involved: patients, caregivers, and clinicians.

Why am I looking at an app to enter blood pressure?

Let me start by saying that ideally nobody should be entering vitals data manually. (Not me, not the patient, not the caregivers, not the assisted-living facility staff.)

Instead, we should all be surrounded by BP machines that easily send their data to some computerized system, and said system should then be able to display and share the data without too much hassle.

But, we don’t yet live in this world, to my frequent mild sorrow. This means that it’s still a major hassle to have regular people track what is probably the number one most useful data for us in internal medicine and geriatrics: blood pressure (BP) & pulse.

Why is BP and pulse data so useful, so often?

To begin with, we need this data when people are feeling unwell, as it helps us assess how serious things might be.

And of course, even when people aren’t acutely ill, we often need this data. That’s because most of our patients are either:

  • Taking medication that affects BP and pulse (like cardiovascular meds, but many others affect as well)
  • Living with a chronic condition that can affect BP and pulse (such as a-fib)
  • All the above

As we know, the occasional office-based measurement is a lousy way to ascertain usual BP (which is relevant for chronic meds), and may not capture episodic disturbances.

The Apple Has Landed

 

Apple transformed portable music players. It redefined what we expect from cell phones. It brought tablet computing to the masses.

Is the company planning to do the same for mobile health?

Some industry watchers think so.

This isn’t a small venture. Apple executives suggest that Healthbook is being positioned as perhaps the key selling point when the company releases its next operating system for iPhone, likely later this year. And the app also may pair with a new “iWatch” that’s under development and will contain biometric sensors.

In his lengthy post, Gurman further details how Healthbook is expected to work. Its interface is “largely inspired” by an existing iPhone application called Passbook, which is intended to centralize a user’s boarding passes, loyalty coupons, and so on in one place. Beyond fitness and diet, the app also has sections devoted to tracking physical activity, our sleeping habits, and hydration.

And Healthbook will offer blood monitoring features—”perhaps the most unique and important elements of the application,” Gurman writes—although it’s unclear exactly what it will track beyond oxygen saturation and glucose levels.

App’s appearance not unexpected

The long-awaited screenshots of Healthbook follow months of reports that Apple’s readying a push into the health care space. While the company’s interest in the sector is nothing new—my team has spent years covering its health-related innovations—Apple’s recent focus has been much more discrete.

Clinic: A Cautionary Note About the Risks of Blood Pressure Treatment in the Elderly

When it comes to high blood pressure treatment in the elderly, the plot continues to thicken.

Last December, a minor controversy erupted when the JNC hypertension guidelines proposed a higher blood pressure (BP) treatment target (150/90) for adults aged 60+.

And now this month, a study in JAMA Internal Medicine reports that over 3 years, among a cohort of 4961 community-dwelling Medicare patients aged 70+ and diagnosed with hypertension, those on blood pressure medication had more serious falls.

Serious falls as in: emergency room visits or hospitalizations for fall-related fracture, brain injury, or dislocation of the hip, knee, shoulder, or jaw. In other words, we talking about real injuries and real patient suffering. (As well as real healthcare utilization, for those who care about such things.)

How many more serious falls are we talking? The study cohort was divided into three groups: no antihypertensive medication (14.1%), moderate intensity treatment (54.6%), and high-intensity treatment (31.3%).

Over the three year follow-up period, a serious fall injury happened to 7.5% of those in the no-antihypertensive group, 9.8% of the moderate-intensity group, and 8.2% of the high-intensity group. In a propensity-matched subcohort, serious falls happened to 7.1% of the no-treatment group, 8.6% of the moderate-intensity group, and 8.5% of the high-intensity group. (Propensity-matching is a technique meant to adjust for confounders – such as overall illness burden — between the three groups.)

The methodologists in the audience should certainly read the paper in detail and go find things to pick apart. For the rest of us, what are the practical take-aways?

Blood Pressure Monitoring, Telemedicine, and Automated Hovering: A Future Model for Disease Management?

Use of an at-home telemonitoring blood pressure device significantly reduced out-of-control high blood pressure, according to a recent study in the Journal of the American Medical Association. It’s another data point showing the potential of telemedicine to have a profound effect on American medicine, by positively modifying health behaviors, providing real-time data to clinicians through “automated hovering,” and helping Americans get and stay healthy – all of which holds the promise of bending the cost curve.

Led by Karen Margolis, MD, MPH, a Senior Investigator at Health Partners Institute for Education and Research, the cluster-randomized study investigated whether using a cloud-connected, at-home blood pressure monitor paired with pharmacist and case manager support would lead to controlled blood pressure more than typical care, which involved check-ups with a physician.

Those using the telemonitoring device were 90% more likely to have controlled blood pressure at both the six and twelve-month checkups than the control group (57.2% and 30%, respectively), and had, on average, statistically significant lower systolic and diastolic readings.

Tele-what?

As a journalist who for the last decade has covered the use of information technology in health care, I’m rather disgusted at some of my brethren in the mass media. I’m none too happy with the medical establishment, either. Both seem hopelessly stuck in the past, refusing to look beyond the status quo. And the public suffers because of it.

This fall, for example, the Los Angeles Times and other news outlets covered a Yale University study that sought to determine whether or not “telemonitoring” heart failure patients recently discharged from the hospital would reduce heart attacks or readmission. The study, published in the New England Journal of Medicine and presented at a November meeting of the American Heath Association, concluded that that telemonitoring, which involved patients calling in their weight measurements and health symptoms after being discharged, made virtually no difference in the outcome. The Times called the trial “a good, commonsense idea that simply didn’t work out.”

Was it, really?

Keeping in touch with one’s physician on a frequent basis after being hospitalized for heart failure is a fine idea, as is monitoring one’s weight. But, as happened in the Yale study, patients generally don’t stick with the program. One in seven study participants never called their doctors, while just 55 percent of patients were making at least three calls per week six months after discharge.Continue reading…
