As someone that both loves technology and has spent considerable time consulting for healthcare companies, the prospect of whichever buzz word you chose to use - Digital Health / e-Health / Health 2.0 - is very exciting. I am talking about the use of web applications, mobile devices, and other gadgets to record, monitor, and analyze personal health information. Not only are these tools efficient and effective ways of collecting health data, but they enable consumers to capture and access their information in new ways.
Generally speaking, there are a few major categories of consumer-oriented digital health tools: web-enabled gadgets, mobile applications, online services, and electronic health platforms. Some of the entrants into these categories are fairly new (e.g., the Fitbit) whereas others have been around for years (e.g., Weight Watchers Online). But whatever their age or level of maturity, they represent a new era for consumer health, where we now have the tools to take the ephemeral concept of fitness and record it, track it, and monitor it. In this post I will profile some of the cool gadgets and services I’ve come across.
Gadgets for Tracking Your Activity-Level and Health
The first device I observed in this space was the Nike+, a sensor that could be worn in a shoe or on a wristband that paired with an iPod to track runs. The data from the sensor could be uploaded to a special website created by Nike for runners that serves as a social network and personal data repository. When it first launched it seemed like just another nifty gadget, but it has been tremendously successful, attracting over a million runners and recording millions of miles run on top of billions of calories consumed. Following on this innovation, many new entries have come upon the digital health scene, including the Fitbit, Philips DirectLife, Wakemate, and Withings Scale. While pedometers have been around for some time, the Fitbit and DirectLife bring some nifty web-enabled features that do much more than any normal pedometer.
The Fitbit records your level of activity (e.g., steps taken, calories burned, distance traveled), measures the quality of your sleep (e.g., time to go to sleep, times awakened, etc.) and automatically transmits this information to a website via a base station / charger. You can use the website to view this data, see trends, or even enter calorie consumption information to get an idea of your overall nutritional intake.
The DirectLife fulfills a similar need, tracking level of activity and uploading it to a personal website. Where it differs from the Fitbit is that is has a feedback display which can be used to determine if you have met your activity goals for the day, and also in how the data it records is used. Philips actually provides a coaching service where your progress is tracked by professionals and they provide advice and guidance on how to adjust your goals.
The Wakemate is a dedicated sleep monitor coupled with an iPhone application.With a special wristband, it records your sleep patterns and uploads it to a website for analysis, informing you of how well you slept and providing data that can be used to do a more thorough analysis. You can also use the gadget to determine the optimal point within a 20-minute window for you to be awakened, ensuring that you will feel better rested in the morning.
The Withings Scale is a well-designed and Internet-connected scale that automatically records your weight, BMI, and level of lean mass vs. fat. This data is sent to a website where it (of course) can be monitored and tracked over time. This saves you from the inconvenience of doing the tracking yourself in a spreadsheet, and allows you to quickly spot patterns in your weight.
Mobile Health and Fitness Applications
What happens when you combine mobility and robust applications? Why, you have the ability to create convenient and highly functional fitness services. Which is what has been done with applications such as Men’s Health and iFitness (though there are dozens more like them). These applications allow you to fulfill your weight management or fitness objectives while on the move, making it easier to accurately record activity and diet information, while also enabling you to view historical information or get tips of workouts. Let’s take a look at the apps themselves to see how they’re designed.
Men’s Health, an interesting play by the magazine of the same type, offers information on specific exercises as well as workouts which are designed to meet different objectives, all illustrated by some nice photography. You can record your repetitions, monitor your rest periods, and export your results via email. This is a very focused application without a lot of distracting features.
iFitness is a very similar application, offering exercises, routines (e.g., workouts), and logging. However, it also allows you to create your own workout program, making it easier to follow a set routine and track progress. In addition to these features, it also has a weight monitor, BMI calculator, and body measurements log. These capabilities allow you to gain a fuller perspective of your level of fitness and changes over time.
I briefly tested these services on my iPhone and found that it is easy to use them. However, you have to be fairly dedicated to incorporate this technology into your routine. It isn’t easy to consistently keep track of your information, especially on the small screen of a mobile device.
Online Services for Logging Data and Monitoring Progress
Another type of service that has emerged over the last few years is online logging and monitoring of health, exercise, and nutrition data. Sites like Weightwatchers, DailyBurn, and The Daily Plate offer users the ability to keep track of just how much they have exercised or eaten in a given day, and also allow you to record key health measurements like weight or BMI. This is usually done by looking up a specific food or exercise, notating how much of it you indulged in, and then clicking a Save button. Just like that, you have captured another page in your health diary.
These tools allow you to capture your net calorie intake, the nutrients you consume, and the sources of your energy (e.g., fat, protein, carbohydrates). Some of these services will let you know if you’re exceeding certain thresholds with your food choices, such as too much sodium. You can easily pull up some analysis on your habits and trend it with your weight to see how effective or ineffective your efforts have been. You can even benefit just by actively monitoring your habits, which forces you to consider your choices and do the math on your diet.
These services also feature meal ideas, recipes, workout videos, and community features. For people struggling to become healthy, they can find almost everything they’ll need through these services, as long as they are comfortable with the digital format. Even in this day and age, a lot of people still prefer trainers and dieticians to help them make the right choices. However, with these tools, everything is quantifiable and its easy to tell if you’re getting results. Do you get the same accountability from your hired fitness help?
Like the mobile applications I discussed, it still takes effort to use these services. You have to be consistent to reap the full benefits. It helps if you can put yourself on a regular regimen, as this saves considerable time when entering data. Some online services have actually started integrating with personal health devices to help reduce the burden of recording information online. As these services mature and technology advances, I hope this kind of data tracking will be automatic and invisible to consumers.
Online Platforms for Consolidating and Sharing Your Information
The heavy-weights of desktop and Internet computing have tried to tackle some of the healthcare system’s problems by launching two online platforms: Google Health and Microsoft HealthVault. These platforms are actually very similar offerings, serving as online portals where you can consolidate your personal health information. You can build your personal health profile, extend it to your family, and share it with physicians. Both platforms have a number of partners that provide information or web applications on top of your data. Google’s partners include CVS Caremark, the Cleveland Clinic, Medco, and Quest Diagnostics. Microsoft has partnered up with organizations such as Aetna, the Mayo Clinic, Planned Parenthood and many others. Web applications leverage these platforms to provide customized content, assess health risks, and monitor health, among other functions.
Other companies have developed platforms to address health from a different angle by targeting employers. Services in this space include Virgin’s HealthMiles, Limeade, and RedBrick Health. These services are directed towards employers, who in some countries like the U.S. pay the majority of health insurance costs. The employers provide access to the service to employees and incenticize them to use them by sponsoring competitions or offering additional benefits and compensation. The services record employee data, provide dashboards for the employees and employers, and help manage rewards. With the help of these services, employees are given the tools to achieve better health and rewarded for the gains they make.
Finally, there is one more service I’d like to profile here: PatientsLikeMe. PatientsLikeMe is an online platform for collecting real-life patient data and outcomes. From a consumer standpoint, it is a support community where you can create a health profile, find others who have conditions or experiences similar to yours, and share knowledge. It is meant to help people cope with their condition, seek advice, or help others by providing relevant information. The founders created the site after an experience with ALS. It is a very different type of platform from the others I’ve profiled, as it helps people in a completely different way. To cover their costs, PatientsLikeMe provides anonymized data to partners and grants access to the community for medical research.
Wait, there’s more
Innovation in health care has also created some more unusual services and gadgets, including Bedpost and the Autom robot health mentor. Bedpost is a tracking site for sexual activity, a sex diary of sorts. While the site is still in beta and doesn’t list the tangible benefits of the service, I’d imagine it can be useful from a health perspective. It is a facet of people’s lives that can be indicative of health problems. The Autom, on the other hand, is similar to a nutrition and exercise log, in robot form. It captures this information and allows users to see a summary. As a tangible and cute object, it is supposed to engage users on a deeper level than health journals. I’m kind of doubtful as to how successful it’ll be, but nice try.
Conclusion
This is simply a tour of the tools and services that are out there, and more are popping up every day. They seek to address everything from obesity to diabetes, using wireless sensors, online applications, and other fancy widgets. Corporate behemoths like Google and Microsoft have entered the market along with small start-ups. Health care is an area that is ripe for innovation and I can only wonder what will come next. Judging from the finalists of the 2010 Wharton Business Plan Competition, where 6 out of 8 entries were health care related, I won’t have to wait long for more interesting ideas to emerge.
