In addition to choosing the right software for the collection of patient information, it's important to choose the right hardware as well. Here are some commonly used hardware devices, their advantages and disadvantages.
1. Stationary Computer with Keyboard and Mouse
good: good for typing large amounts of data, particularly free-text clinical notes and discussions
bad: using a keyboard and mouse is a learned skill - not everybody can do it
best for: entry of large amounts of data
2. Computer with Touchscreen Monitor
good: easy to use - anybody can point
bad: less screen real estate (some is taken by on-screen keyboard/keypad), touchscreen isn't always accurate
best for: entry of shorter forms, and where user is less likely to be skilled typist
3. Mobile Phone
good: very portable, low-power, population saturation (everybody has one), cheap
bad: very small screen, hard to type words/sentences
best for: simple data collection while on the move
4. Smartphone
good: very portable, low-power, can run applications that make data capture easier or more accurate
bad: very small screen, more expensive that regular phone, less prevalent than regular phone
best for: relatively simple data collection while on the move
What other devices are out there that can help facilitate patient data capture?

We are experimenting with smart tag-enabled patient health posters that can be read by an affordable reader, such as an NFC-enabled cell phone, to aggregate health information based on 'taps' on a common symptom grid. These guides to diseases and symptoms are often found in held posts in the form of a wall poster, or graphical flip books. They provide a quick reference for workers. Since are already used to referring to them, we think they can provide a natural gateway for us to capture passive information about the patient.

Dear ALL,
Recently I tried HTC 4350. Key advantages are:
- notes in notepad, word is possible. One can store data in excel
- uploading softwares is possible
- minutes can be sound recorded
- font size can be increased even though screen is small
Can anyone inform me any statistics software for windows mobile phone available for free use?
Best wishes
Singh

Dear Jose,
Season Greetings
I plan to introduce similar approach in community based MDR TB project. Could you please tell me where from I can download relevant software program for low cost mobile phones, preferably nokia sets and windows mobile.
Best regards,
Dr. Singh

Hi all, I think Christian's covered the general spectrum of devices we can use. To take this further, it helps to determine what data we want to capture and what technology we're using to capture that data.
expand commentRight now I can think of two general groups:
1. Electronic identification of anything. For example, if patients are identified using smart cards/ RFID tags, barcodes, or biometrics, a device that has the capability to capture that information without manual entry might be in order. This type of identification like Jose mentioned, might not be limited to patient identification, but could be given to a flip chart of symptoms, or lab results and that data can be electronically captured without physical entry by a user. Here's an example of one project where we've used this in Pakistan as some food for thought. http://www.youtube.com/watch?v=lWl9TNOqZog
2. GPS/image/video/voice - Do we need a device that captures GPS as well? This could be useful for community care in areas that don't have street addresses, or a geographic plot of disease prevalence might be useful, etc. Or maybe you need an image/sound/video recording ...

Hi all, I'm aware of a pretty decent open source, web-based application for keeping track of information like this. LabKey Server is used actively by folks in the field of HIV/AIDS research. I pulled this detailed case study from their web site, which describes how the Bill and Melinda Gates Funded SCHARP organization uses their system to manage clinical and scientific data collects across literally hundreds of labs and data collection points. http://labkey.com/resources/LabKey_SCHARP_Case_Study_Full_Document.pdf. Something like this should do the job if folks like the open source approach and data needs to be collected and easily shared.
