Enhancing self-care and personal health monitoring with smart phones

ahoccc | 29 September, 2006 23:05

Imagine the case where your doctor has prescribed you to take e.g. blood pressure measurements at home regularly for some time period. You should write down all the measurement results and bring the result log to the doctor after monitoring period.

 

Ok, you take the measurements and write them down. Few times you perhaps forgot to write measurement down and you write it down later trying to remember what the measurement result was. Then you take them to your doctor. Doctor looks results and perhaps types them into clinic information system and then gives you a feedback.

 

So, what’s the point here? This is just normal routine to do.

I would like to introduce alternative way to do this using today’s smart phones.

 

In my opinion, the combination of self-monitoring devices with mobile technology offers several advantages in comparison with traditional monitoring methods. In personal health monitoring with smart phones accurate measurement results are available to health care professionals in almost real time regardless of your location. Your personal treatment can be monitored and quickly adapted to a change in health status. Furthermore, by being able to follow the progress of your own treatment, you are more motivated to follow the prescribed therapy.

 

Smart phones can offer mobile solutions to collect measurements results automatically and wirelessly from the measuring devices and seamlessly transfer the collected data to the healthcare personnel for further analysis. Since smart phones today have well enough storage and processing capabilities they can be used to collect, store and transfer information from different measuring devices at a same time. For example, a blood pressure monitor, a weighing scale and a glucometer can be used to collect and register key information in diabetes care.

Results from different measurement devices are linked together and immediately forwarded by using mobile networks like GPRS and 3G to the healthcare provider, where they are available for review. Following the analysis, the healthcare professionals can send feedback back to your mobile phone. As a result, you not only remain informed about your health status via the information displayed on your mobile, but you can also quickly adapt your treatment, diet or exercise programme in response to the medical advice you receive from your healthcare provider.

 

In addition to this, you can even view the results on a list or have them displayed in a clear graphical form directly on the screen of the mobile device. This gives you an immediate overview of your treatment progress.

Sounds quite far fetched? Not really, this is actually reality today and the presented eHealthMonitor application exists commercially for the Series40, Series60 and Series80 devices.

tote_b5 Arto,

I'm just wondering when those commonly used devices, like blood pressure meter, weighing scale, etc. will be capabile of communicating with wireless devices. That's one thing that eHealthMonitor is available for the public, but what about the aforementioned devices. I think _that_ would be a big step towards getting this system work.

ahoccc Tote,

You are correct that connection to the measuring devices should be wireless to enable the full use of eHealthMonitor. My answer to this is easy since the eHealthMonitor already communicates wirelessly with every device it supports. There are already measuring devices "off-the-shelf" that can communicate wirelessly using Bluetooth or infrared. There are Bluetooth blood pressure meters, scales, ECG devices, EMG devices, pulseoximeters, peakflow meters etc. But of course these Bluetooth devices are quite new phenomena in the medical device markets and there are some problematic issues how medical device manufacturers have implemented the Bluetooth. I have presented these issues in two of my previous blogs:

- Connectivity with medical POC devices, background (https://blogs.forum.nokia.com/view_entry.html?id=87)

- Connectivity with medical POC devices, bluejacking? (https://blogs.forum.nokia.com/view_entry.html?id=90)

Also many of the measuring devices still communicate with RS-232 or serial-converted-USB or infrared. These devices cannot be directly plugged to today's smart phones. But for these kind of meters an adapter module must be used that converts serial and infrared to Bluetooth. I have been involved in one this kind of module called eLink. You can find presentation of eLink here http://www.ehit.fi/resources/userfiles/File/Brochure_eLink.pdf. Using eLink, eHealthMonitor can support cable measurement devices as well as infrared devices even that the smart phone supports only Bluetooth.

Very interesting post.

i have been working on a similar issue two years ago in denmark, the Aalborg university was, and may be still is busy with a very large scale PAN project, within which a small part was devoted to self-care, and especially for diabetes patients.
it was .net devel, and connected to a computer with a very precise model of glucose evolution in blood, in order to help the patient with his self-medication. All that was to help reduicing the number of visits at the doctor's office.
One of the point was to replace the doctor at the clinic, most of the time, i.e. as long as the blood glucose remains in acceptable values, by this model, and to contact immediatly a doctor as soon as the blood glucose level reachs a potentially dangerous value, with all previous measurement available easily.

All this is certainly going to change our vision of medication
