MedWatcher is a mobile application trying to streamline this process, and increase public (patient) participation in pharmacovigilence. FYI- it’s not out yet (some sources projected Aug 2010 release, but I couldn’t find it in iTunes), so all that is known is intended functionality.

The application will serve two major purposes. First, users can receive drug-related alerts through it, based on FDA MedWatch and less-formal sources (news, media etc.). FDA MedWatch may be a treasure-trove of information, but it’s not easy to use. You can subscribe to an RSS feed, get email or text messages about all drug-related warnings. With tens of thousands of drugs on the market, that is like drinking from a fire hose.

If you are a patient worried about your cholesterol-lowering Zocor or a cardiologist who wants to stay informed about statins in general, there needs to be a way to subscribe to only what you care about. I’m hoping that MedWatcher leverages a comprehensive drug-database like FDB, Medi-Span, Red Book etc. to lets users do exactly that.

The second major functionality is for users (both patients and provider) to submit side-effects through a lean process. They mention that serious side-effects will ‘automatically’ be submitted to FDA (rest probably become discussion topics on MedWatcher itself). The current FDA MedWatch online reporting process is cumbersome and a bit disconnected (who remembers to submit voluntary information after they have seen/experienced a side-effect?).  Having a user-friendly mobile application form would solve some of that.

I think the direct patient engagement is very promising in this niche space. The concept may run the risk of becoming yelp for drugs, but even yelp reviews hold useful information once you figure out how to get rid of the noise. By opening direct communication channel with patients, it has the potential to provide the same disintermediation that TrialX provides for clinical trials.

Seems like there are three components of the overall offering:

1. A hardware device called “Spiroscout” – a small add-on that mounts the inhaler canister. Every time it is pushed, the location and time-stamp data is recorded.
2. Mobile app – a ‘diary’ to keep track of symptoms, triggers, medications, etc. Can also be used to view map of data received from Spiroscout, and to get sms reminders for taking medication.
3. Online website – a ‘dashboard’ of sorts. Can help summarize submitted data to figure out disease patterns and trends.

The hardware device is not out yet (website says it’ll be out this summer), and the mobile app is currently in private beta. So there is not much of real world testing that has happened. But I’m still positive about Asthmapolis, for a number of reasons.

First, it’s the right kind of ‘focused’ monitoring solution that can potentially be transformative for managing a specific disease (kinda like Regina Herzlinger‘s argument about ‘Focused Factories‘ as one of the ways to salvage the entire healthcare system). It’s better than trying to find a solution that can monitor multiple conditions (example 1, example 2). I think the mobile diary and online dashboard would be key engagement tools in this regard. The more focused and customizable, the better.

Second, it helps in medication adherence which is a big issue irrespective of the medical condition. I think that knowing whether you took your medications and getting reminders if you didn’t,  is more powerful than knowing when/where you took it. The mobile app reminders would be a great resource there (automated calls to landlines may be good too…for seniors).

Third, it helps understand the individual triggers and community impact of asthma. For successful asthma management, a patient should know his/her triggers and avoid getting exposed to them. That is not an easy task for a number of reasons. My initial reaction was that GPS may be a bit of an overkill. But with rapidly decreasing cost of location-aware technology, why not? Much better than using it to check-in to nearby McDonalds.

Rochester, NY based Logical Images is the company behind VisualDx. Understandably enough, it was founded by two dermatologists from University of Rochester in 1999. At its core lies a pretty big repository of clinical images (they claim > 60K) that are tagged with clinical metadata like symptoms, location, history etc. A user can browse through diagnosis domains or input findings to reach a relevant set of images.

There is a 15-day trial for non-enterprise users, and individual subscription pricing ranges from $49.99 (Pediatric) to $99.99 (Adult) for a year. Student discounts brings it down to a very reasonable level ($29.99 and $49.99 respectively) in my view. The company has leveraged their content to create an online consumer health resource called Skinsight. Besides the clever name, I really liked their slick ‘Skin Condition Finder‘ tool. Overall, it’s a smart approach for gaining market recognition and expanding services.

The concept of Diagnostic Decision Support (DDS) often comes with the implicit notion of text-based query, so I really like the ‘visual’ DDS approach. Dermatology, Pathology are obvious choices to implement such an approach and situations like ER, bioterrorism, infectious diseases are prime contexts since there is not enough time to engage a pure text-based knowledge base. Also, some conditions are rare enough that most practicing physicians and non-specialists haven’t actually seen one in real life. Other factors like dark skin, atypical presentation can be confounding. It’s handy to have a this as a medical education tool and as a care delivery aid in facilities where specialists are not available all the time.

I’m bit surprised why it’s not a widely subscribed resource in hospitals, public health entities, medical education and general EMR vendor products. Anyway, it’d be interesting to see this visual content embedded in other consumer tools (like iTriage, FreeMD) and enterprise offerings (Isabel Healthcare, SimulConsult, Curbside.MD etc.). Wonder which firms are competitors for VisualDx today…

The Life Pebble hardware includes a single lead ECG, skin thermometer, and an accelerometer. The data collected by the system is streamed wirelessly to a USB Network Adapter over short distances. According to MobiHealthNews, the device is currently in clinical trials are few US hospitals and Toumaz has declared an intention to submit for FDA clearance in 2011. This continuous physiological monitoring capability is currently marketed for assisted living, rehabilitation and professional sports applications by the company.

If we can put aside the “who will pay for this?” question for a minute, this kind of technology has myriad applications in both consumer and provider space. What is chunky hardware today, will almost surely be a disposable, thin patch tomorrow. If we can have a reliable way to do real-time monitoring of key vitals, disease management is no longer confined to interactions in the healthcare setting.

What intrigues me is how the trend of medical-grade remote monitoring (which is moving outside of hospital setting with technologies like Sensium) will interact with the trend of consumer-oriented remote monitoring (FitBit, DirectLife, BodyMedia, Zeo, etc.). There will be a shakeout, obviously. My guess is that the winners then will be not be defined by which way and how much data they gather, but what they do with that data. Analytics and interpretation will be the differentiators.

With that background, Corventis becomes an interesting entrant to the MCOT space. Their technology platform consists of a bandaid-size wireless sensor patch called (“PiiX”) that detects, records and transmits physiological data to a portable hub (called “zLink”). zLink is a cellphone-size device that sends the data over wireless network to ‘Corventis Monitoring Center’, which is a staffed to do preliminary interpretation and urgent physician notification. They offer these capabilities in two forms: NUVANT (ECG based continuous arrhythmia monitoring) and AVIVO (non-ECG physiological paramters monitoring). Corventis has some big venture names behind it: KPCB, Mohr Davidow, DAG ventures. They recently got FDA clearance for NUVANT in January 2010.

Cardiac diseases are certainly the prime target for any wireless remote monitoring startup. Corventis is not alone. iRhythm’s Zio Patch is designed to diagnose cardiac arrhythmia by providing  up to 14 days of continuous recording. Once done, the Zio Patch can be mailed back to the company for analysis. Unfortunately, the Achilles heel for all of these companies is reimbursement. So far, private insurance companies and CMS are not convinced that such services are worth paying for. MobiHealthNews has an interesting post about this trend here.

I’ve written about a number of consumer-oriented ‘wellness’ services by startups that are using wireless sensors to detect simple metrics like activity and help you achieve a healthy lifestyle. Corventis, iRhythm are good examples of medical-grade services utilizing the same basic technical framework and abilities for managing life-threatening conditions. Once we get over the barrier for reimbursement, you can bet on the remote monitoring market for serious medical conditions exploding. We can wait for that to happen, but I’m personally convinced that as consumers take more charge in managing their conditions (and health insurance continues to spiral the drain from a cost and outcome perspective), there is a growing scope for remote monitoring services that consumers will pay for themselves.

PS: I had a discussion with Corventis founder, Darryl Drinan a few weeks ago. He had three insightful comments for anyone thinking about getting into the remote monitoring space:

• If you have a choice, focus on therapeutic service, not diagnostic
• Product alone is not enough, always tie it to a service
• Patient education is a big problem (if you need to do it for them to use your device, you are hosed)

ScanAvert is an interesting paid application of the same functionality. It allows users to scan the usual UPC barcode information on their supermarket items and cross-check the ingredients with their health profile. Consumers register and create their profile with facts like allergies, prescriptions, diagnoses, dietary needs, etc. ScanAvert uses data provided by Gladson (a major CPG product images and information provider) to do real-time checks on the ingredients of the item to detect incompatibilities. Now I know the usual critique would be that why wouldn’t the consumer just read the ingredient list or package label? And the counter would be that an average consumer may not find the information easily readable or understandable.

Those and other evident arguments aside, the service has obvious value for people with serious dietary issues (think gluten allergy, Celiac, Diabetes, Obesity, Prescription drug interactions). But I’m more excited about another aspect of the service- ScanAvert users can specify custom limits on a labels nutritional box values (calories, carbs, fat…) and get instant recommendation. To me, that is pretty useful for the rest of the population that doesn’t deal with any significant dietary restrictions. In fact, most of us end up buying food items without paying much attention to what it means nutritionally. Even those few that give a thought to the nutritional box items, the mental calculation done is only at a high level (“100 Cal drink…sounds low….I’ll try that”) and inconsistent (how many times have you checked the fat vs. saturated fat numbers?). I doubt most of the ‘normal’ population even knows what is their actual average dietary intake in terms of calories, fat, proteins, etc.

So if someone can setup a profile that puts a limit on the daily fat/protein/cal intake and have a real-time summary report given to them while they were grocery shopping, that would be an darn useful service, I think. Seems like currently ScanAvert can also suggest alternatives (if it detects incompatibility) and send alerts about scanned items that have been recalled. That makes the service even more useful.

It’s intriguing to think about expanding this service into a space where it can potentially be the long-term dietary record for an individual. Suppose one could combine that with a personal activity monitor like FitBit.  That would make a great ‘wellness solution’ for an individual to record, analyze, set goals and then get guidance on two important aspects:

1. Energy input (your food intake)
2. Energy output (your daily activity)

I also found some other apps that help manage food allergies (FoodContentAlerts, iCanEat/iEatOut), although they don’t have bar code scanning ability. This space just keeps getting more interesting every day.

At the core is a symptom-checker that lets users do a high-level categorization of what could be wrong with them, and how serious/not can it be. That functionality is nothing special, since there are multiple services that do that both online and mobile. Also included is a nationwide directory of care facilities (including urgent care, retail clinics, pharmacies and physician offices) and nurse advice phonelines (sorted by insurance provider). Your smartphone knows where you are, so the neat service is to be able to find directions to the nearest facility with few clicks. It may not sound like much; but when you are away from home, it’s pretty useful to be able to quickly figure out the nearest urgent care or retail clinic. iTriage is also trying to take this service to another level with the addition of ‘ER wait times‘ functionality in select cities. That way a user can further filter out the facilities based on wait times. Even if this is not really present/reliable in your area today, I think it’s a brilliant extension of a service like iTriage. Because its not a question of if this will be useful, but when. Once there is a critical mass of hospitals in an area submitting their ER-time feed to iTriage, the rest will find it hard not to do the same. There is a need for public to have a near real-time pulse on ER utilization, and services like iTriage provide a good platform for it.

The other interesting aspect is their partner service integration. Healthgrades provides the physician/hospital quality reports within iTriage, although users need to pay to get info beyond minimal basic report. Teladoc provides the 24×7 physician advise service (its phone consultations are for under 40$ mostly). They also partner with a claims adjudication organization (name?) that helps consumers negotiate thier medical bills. One can argue that a lot of the above functionality can be accomplished with a mobile browser or search app. But the value-add of a dedicated app is to provide fast, context-relevant info and be a steady companion as the user traverses the acute healthcare system.

I heard Paul Hudson, MD (co-founder) speak at the Mobile Health 2010 conference last month. He used an intriguing term to describe their technology: “symptom-to-provider technology”. Guess that is one way to think about a IT service that holds your hand from beginning to end of an acute care episode. He placed iTriage in the “multi-billion $ self-referral market”, and gave couple of interesting factoids about it’s current utilization:

• Around 89% iTraige members are commercially insured
• It’s use has gone beyond Emergency care in some cases- people have used the Healthgrades info to switch providers

Both of those underscore the fact that consumers need a trusted guide in handling how they interact with the acute care system. ERs, Urgent Care centers are the way most people experience care delivery most of the time, and having insurance doesn’t really help in making a good choice. With mobile phones getting smarter, the ‘self-referral’ market is ripe for innovative services.

Child Count is an mHealth platform developed by the Millennium Villages Project aimed at empowering communities to improve child survival and maternal health. It facilitates the activities of field-based community health care workers in Africa.  Using any standard phone, these workers are able to use text messages to register patients and report their health status to a central web dashboard that provides a real-time view of the overall community health. This enables an automated system that helps reduce gaps in treatment (sms-based rapid diagnosis, follow-up reminders etc.).

ChildCount is open-source. It’s built with RapidSMS, a  framework that manages data collection, complex workflows, and group coordination using basic mobile phones. This short video does a good job of explaining the overall project and technology.

Public Health interventions are often based on simple logic, but have far-reaching effects. Screening regularly for malnutrition, malaria, diarrhea, etc. requires relatively simple documentation and measurements- making it perfect for sms-based communication. Even keeping a simple registry of births, deaths, immunization status enables local health teams and organizations optimize their efforts. Care delivery organizations in developed countries should also think about integrating the mobile platform into their services- its a great way to interact and keep in touch with patients. Medication adherence is a good example. NCPIE‘s 2007 report states that poor medication adherence is almost a crisis, costing $177B annually. Almost any population care management topic (outreach, screening, compliance, etc) would be a good use case.

Child Count is in good company -there are many interesting mHealth applications out there that deserve mention. The mHealth wikipedia page has a good running list of some applications. I’ll continue to post about what I discover and like.

Remote motion-sensor based alarm clocks are probably a nerdy gizmo for now. But it does provide a good use case of how everyday appliances are getting smarter and generating volumes of data. It’ll be very interesting to see how such data can be leveraged to further sleep disorder research- as I wrote in my Zeo post.

Note that there are other products out there that offer the same functionality: FitBit, WakeMate, SleepTracker, and the somewhat unique Zeo.

GlowCaps fits the standard pill container, and uses short-range wireless communication to talk to a gateway hub at home that is connect to the internet. There is also a reminder light (looks like a night light) that plugs into any standard power outlet. If the bottle isn’t opened at the appointed time, the cap and night light start blinking to remind the owner to take the medication. If after an hour, the pill is still not taken, GlowCap starts start playing jingles as well. After yet another hour, it’ll send a message to Vitality’s system which can then place an automated phone call or send a text message with a reminder. Brilliant.

Beyond having a ‘smart lid’ for bottles, Vitality has integrated functionality that keeps caregivers in loop. There are social support features (shareable weekly email reports), refill facilitation (refill reminder calls) and physician interaction tools (printed monthly reports to you/doctor). So it hits all the major interaction points for a patient’s medication regimen. Last month AT&T put out a press release about GlowCaps running on its wireless network. So the Vitality gateway now has mobile phone technology, and I assume that precludes the need for an ethernet connection.

Every clinician knows that medication adherence is a huge problem ($100B figure has been thrown around as the cost of poor adherence in US). More than a consumer product, this is a fantastic service that can change medication packaging in general. And looking at the Managed Care (enhance the personal/medical record), Research (change patient behavior) and Pharma (reduce brand-switching) focused pages of their website, I think Vitality knows that. It’s definitely the next stage in evolution of the standard pill dispensers (like ePill, Philips).

Their CEO David Rose has an interesting background in creating internet-connected everyday devices at his last company, Ambient Devices. Somewhere in a press release I read his quote about “…providing minute-by-minute adherence data to motivate healthy behavior.” If you take the word ‘adherence’ out, that may be a basis for a lot of future medical solutions and an adage for next-generation of medical device companies.

gDitty is targeted towards promoting physical activity in kids. The product combines an activity meter device (on belt or in pocket) with an online rewards program that motivates kids to move more. The program is in a private research trial mode, so details are unavailable. But it seems that data recorded by the device is uploaded to a custom website, and translated into points of some sort. Points can be then redeemed for certain virtual and real-world rewards like avatars, gift cards, etc.

Trends in childhood obesity are alarming, to say the least. Although I’m a bit skeptical about promoting reward-seeking behavior in younger generation. There is a lot of that going on already. Maybe induce loss aversion instead? We are wired to strongly prefer avoiding losses to making gains, Kahneman & Tversky proved that.

Behavioral psychology argument aside, I realize that encouraging movement through rewards is probably more applicable to kids age-group than adults. I recently met someone from Green Goose- it’s a startup in pre-launch beta mode with similar offering for adults. They deploy tiny activity sensors in way that helps track your daily activities (biking, brushing, water bottle, shower-head, key chain etc.). The recorded data is converted into points, and you get the incentive to transfer money into savings or compete with your friends.

It’s a public private partnership that provides this educational program. The list  is impressive: CTIA,  HMHB, Johnson & Johnson, WellPoint, Pfizer and CareFirst BCBS, BabyCenter, George Washington University and MTV Networks among others. U.S. government partners include the White House Office of Science and Technology Policy, the Department of Health and Human Services and the Department of Defense Military Health System. The mobile health platform is provided by Voxiva and fifteen U.S. carriers have agreed to carry the program’s text messages at no cost for two full years.

91% of US residents have a cellphone, compared to 22% that have internet connectivity. Educating pregnant women and new moms with information they need to take care of own and baby’s health is a powerful preventive measure. So there is reach and utility in this idea, no doubt.

Note: Found interesting background about Voxiva. They started in 1999 with the idea that mobile phones were going to play an important part in health going forward. They now have a technology platform and provide mobile health solutions in about 14 countries (mostly developing countries like India, Mexico, Rwanda, Peru). They market and sell to public health agencies and government providers usually, but are moving into phara and provider networks now. An insightful interview with thier founder here.

Yes, I’m thinking the same thing. Why would you want to tweet something like that? And who the heck wants to be spammed by other peoples weight info?

Those obvious questions aside, its the trend that I find interesting. As the commodity devices that measure one or more of our vitals become web-enabled, ‘wellness’ goes beyond just being about purchase of a product. It gets transformed into a service. Withings is already compatible with a growing list of partners like DailyBurn, FitOrbit that provide fitness and personal training services. They also integrate with the big PHR platforms – Google Health and Microsoft Healthvault. So in theory, someone struggling with obesity could very well use the regular measurements from Withings device, social support from twitter followers, professional coaching through FitOrbit and health record from Google to try and achieve their ideal weight.

‘Connected Appliances’ are what Withings team envisions. They are not alone. I’ve written about several  analogous monitoring devices with some sort of web-integrated service (Read about Zeo, FitBit, Directlife, BodyMedia…). Although most of these focus on ‘wellness’ currently, they are setting an important precedent for managing ‘health’ conditions in a similar way. Consider the ‘how-does-work’ visual from the Withings website:

Now replace ‘weight’ with ‘Blood Pressure’ or ‘HbA1c‘ and you get the framework for managing health conditions (hypertension or diabetes, respectively). Take J&J’s spinoff, SymCare, for example. They are following the same framework for evolving the traditional glucometer. Lookout for more medical devices to move in the same direction.

In an effort to understand what is unique about Zumi Life, I stumbled upon this interview with its CEO. Crunchbase tells me that they started with $700k seed funding in 2007 and got a Series A infusion of $1M in April 2008. With that context, several questions come to mind. Zume Life needs manual input for all the data it needs from the user- and that assumes the user to be reliable enough to put it in. If Zuri had a sensor to automatically capture the critical vitals (like Zeo, Bodymedia, DirectLife, FitBit, LifeShirt and scores of other devices), that would make it infinitely more useful. But I understand that there is no automatic sensor for your mood or for what you just ate, so somethings need to be captured manually. Which is why there are services like RememberItNow, Reqall, Zealog, Polka etc. Still, why not get the medication list for Zuri from PHR platforms like Google Heath? If we assume that the chronically ill and overworked individual remembers to input their care regimen in one place, why wouldn’t they use a simple paper sticky note or a smartphone reminder app? Even a simple Google Calendar or 30Boxes event can be configured to deliver reminder emails that show up as audible, sms alerts on your phone. So is there really a need for a dedicated hardware device in a world that is slowly converging mobile computing platforms? Zuri reminds me of the device that is made to do twitter only.

The price tag was also a bit of surprise. Although there is no official mention of pricing on the Zume Life website, I found a PCmag article from Sept’09 that quotes $35/month or $300/year for the service, and $4.99 for the iPhone app. That sounds way too much money for a basic alerting and journal-keeping service that is 100% manual entry based.

Of course, it’s easy to criticize others idea. I don’t have the complete facts on the service, its utilization and its founder’s vision. The overall trend of using patient-oriented hardware devices integrated with web and mobile dashboard/analytics to manage chronic conditions is for real. I just think sensors are a key aspect of such devices and that pricing can be Achilles heel for adoption.

Zeo system consists of a wearable headband that measure brain’s natural electrical activity. Although their blog has a high-level explanation of how it works, my understanding is that its a single-channel EEG, which seems to be a reasonable way to do sleep analysis in healthy individuals. That data is wirelessly transmitted to a bedside display and stored on an SD card.

Algorithms based on proprietary logic churn out a personal sleep score (called ZQ) to quantify the type of sleep you get. The display unit looks like a bedside alarm clock and shows current and past 2 weeks worth of sleep analysis. Also has some smart alarm clock features like SmartWake alarm that wakes you up at the most suitable time within half-hour of set time. You could upload the data to an online sleep journal through the SD card. The website gives graphs, trends and the ability log other supplementary lifestyle data that can affect your sleep. All that for $249. An additional $100 would get lifetime access to a personal sleep coaching program, which includes regular assessments, goal tracking, email tips etc.

There is no question that Sleep Science is a serious, mature field. Zeo can find its place as a useful adjunct for plenty of sleep-related disorders that affect people who are otherwise healthy. It’s not an FDA approved 11 channel medical grade polysomnogram, and it’d be a mistake to compare it to one. It’s perhaps a closer analog to Actigraphy where a wearable sensor measures overall motor activity during sleep. An actigraph unit is an accelerometer based device like the FitBit, WakeMate, SleepTracker or Axbo.

Accurate or not, Zeo is yet another proof that healthcare is slowly being transformed by sensor-based, portable devices that are capable of analyzing data in a consumer-oriented way to enable individual patient to manage their conditions better.

April ’10 Update: I ordered a Zeo from Amazon in March’10. Been using it for couple of weeks now. The hardware looks and performs well, but I have my complaints. The sensor in headband is bit bulky to sleep with, and I don’t think I’ll get used to the headband anytime soon. The fact that I need to replace the sensor pad every 90 days feels like a hidden cost (they are $24.95  for a pair without S&H) that was not disclosed completely in the marketing.

Software-wise, it’s bit less intuitive than I expected. I’m still wondering what the data tells me. I know Z-score is a overall indicator, but what about the breakdown? Are my 49 minutes of deep sleep enough?  The fact that I woke up 7 times – is that normal? In the end, I’m asking the question- what does this $250 device do for me…  Probably not much because I’m not the target audience for it. People suffering from sleep disorders would perhaps be more receptive.

May’10 Update: Returned it. Sorry Zeo. Still feels like I’m missing out on something… just don’t know what exactly.

June’10 Update: Learned about the Zeo API. Mobile fitness companies RunKeeper and Daily Burn are the first to integrate their services with Zeo. Neat strategy to promote it as a platform.

July’10 Update: Found out about NeuroVigil: another startup in the sleep-monitoring space. Their technology is also based on a single-channel EEG wireless sensor. They claim to be able to send the data (and its analysis) to any mobile device. NeuroVigil’s founder, Philip Low gave an interesting talk at TEDMED in 2009.

FreeMD is the free online version of the same underlying triage application. It  uses video to conduct the interview, ask questions and then generates a custom web page that contains care instructions and suggested next steps. I tested it with a few hypothetical cases (from benign nose bleed to serious UTI) and it seemed to do fine for basic diagnosis. With vague complaints like diffuse abdominal pain and vomiting, it stayed roughly in the right categories at a high-level (appendicitis, pancreatitis, kidney stones, gallbladder disease, intestinal obstruction).

Is the underlying logic based on hierarchical structured programming or a more sophisticated expert system with forward and backward chaining algorithms? I don’t know. My interest in FreeMD spiked when I saw the 100K+ unique visitors/month statistic. They are consistently generating a lot of traffic, so there’s got to be fairly comprehensive content and at least some utility in the service. My personal impression is that as a patient-oriented triage tool, it does well. Of course, provider-oriented decision support is tougher and I don’t expect it to hold up like Mcyin or DXplain.

I’m also intrigued why DSHI systems chose to make their application available for free, when the revenue model seems to be based on licensing/co-branding with partners. I was half-expecting to see a feedback loop on FreeMD (like “Was this the right diagnosis? Let us know”) since one of the major reasons for open-sourcing anything is to leverage wisdom of crowds. But there isn’t anything like that, so maybe its all about gaining awareness and marketing the application.

Update: Connected with Dr. Steven Schueler after writing this post. He correctly identified that FreeMD is a triage system, so its a bit unfair to compare it with diagnostic decision support systems like Mycin/DXplain.

I was fortunate to see a demo last month. At the core of the offering is a set of remote sensors- a heart rate monitor (worn as a strap around torso) and a stride sensor (clips on to shoes, and measures stride pattern, distance and speed). These communicate wirelessly to a central unit called ‘Pacer’ (MSRP $139.99) which connects with your mp3 player and gives audio feedback about things like calories burned, distance, workout progress etc. Another peripheral that communicates with both sensors is the ‘Zone’ (MSRP $69.99) which is worn on wrist, and gives constant visual feedback (using colors) about your heart rate zone. Pacer connects and syncs to the personalized website, zone doesn’t. Coupled with all that hardware are workout ‘plans’ for your goals like run faster, get fit, loose weight, learn to run or to reduce stress.

My initial impression is that it all sounds too complex and too expensive. But maybe this is legit functionality for people who are serious about running. For the novice consumer who wants to track daily physical activity, I like the simple approach of FitBit. For those who run regularly, the Nike+ Ipod offering is another (much) cheaper competitor. Either way, miCoach is yet another sign that consumer-oriented wellness monitoring solutions are becoming mainstream. Next logical phase would be moving similar technologies and frameworks to tackle real disease management and prevention.

• VISICU (a remote ICU monitoring technology company acquired in 2007)
• Digital Pathology (commercial offering in 2009)
• Motiva (Remote patient management and education delivered through television)
• TeleStation (In-home hub for two-way communication between provider and patients with chronic diseases, integrated with wireless measurement devices)
• LifeLine (focused on preventing falls and medication errors for seniors)

The list above is not comprehensive by any means, it’s just what I could recall right away. Without making this a post about Philips’ strategy, here is the latest addition to my personal list of innovative Philips Healthcare IT offerings- DirectLife activity monitor. It tracks your physical activity (through a triple axis accelerometer) to calculate calories burned. Results show up on a personal webpage (detailed) and on the device (simple indicator lights).

It’s like FitBit, but with some design differences – DirectLife is waterproof and needs USB-based sync (FitBit is wireless through a hub). Most importantly, DirectLife comes with a coach- a real person to provide inspiration and assistance to meet your target weight or activity level. The device (hardware) is $99, but coaching is a monthly subscription of $12.95 (first four months free).

The entry of Philips in this lifestyle-tracking arena makes the proposition more legit for mass adoption- now the HR departments of large enterprises  can think of offering it as a health benefit, maybe health insurance companies will pay attention too. FitBit is a great device in itself, but what’s needed is a “wellness service”, much like what DirectLife is starting to sound like. My prediction is that we’ll see proliferation of such services in the next few years- maybe even a lower premium option in your medical insurance if you choose an integrated activity tracking service.

Sure all this can be a simple iPhone app (maybe there is already one out there) or even a one-line cryptic entry in your google calendar. My point is not to critique the utility of an independent website to track one’s sex life. I’m reflecting on the overall trend of niche health and wellness ‘trackers’ (read my previous posts about FitBit, Proactive Sleep, ZeaLog, Qwitter). Given the myriad sexual disorders (e.g. Erectile Dysfunction) and their probable causes, an application like this could provide rich history for clinicians. Overall, it underscores the importance of web 2.0 technologies in enabling consumers to keep granular, accurate health records.

Update: Few weeks after writing this post, I found a number of mobile apps (with integrated online version) that let you count/track anything you want. Few examples: TallyZoo, Dayta, Daytum, TheCarrot. There are also multiple websites that let you track and analyze anything- Graphomatic, Kibotzer, Track-n-Graph, Me-trics, LifeMetric, DailyDiary.

The website is not currently recommended for clinical use- mainly because the images have not yet been verified by pill manufacturers. Still, it’s a smart tool that can benefit multiple care settings. Many seniors coming through the emergency room and clinics don’t remember the name of their pills, but can recall its visual characteristics. A tool like this can be a great addition to EMRs and even PHRs.
