Lately, there has been a lot of press about handheld devices and how they will revolutionize healthcare. Call me the iDinosaur because I’m having a hard time seeing how anyone has yet to put together the right mix of tools to really make a handheld any more productive than the good old fashioned tablet PC!
Case in point: several months ago, a colleague eagerly acquired an iPad and proclaimed that printed media was a thing of the past. He could do all he needed to do with his iPad and didn’t need his laptop any longer. Interestingly enough, the last time I saw him, he was using his laptop. When I inquired about the iPad, he said it was for sale on eBay! It seems once the novelty wore off, it wasn’t as robust as he thought it was.
What are the primary things a handheld should offer a physician?
- Ability to document patient encounters (notes, history, etc.)
- Ability to order studies and tests (CPOE)
- Ability to prescribe medications
- Ability to access prior patient records and test results
- Ability to search the web for specific disease or medication information
- Ability to access reference material
- Ability to communicate with other clinicians or the patient (email, instant messaging, etc.)
- Ability to place/receive phone calls from staff, physicians, patients, and facilities
What technologies exist to enable the physician to do these things?
- Textual information input in the form of dedicated keyboards or pseudo keyboards
- Voice input in the form of voice and speech recognition applications for command and speech-to-text entry
- Visual display of information through some form of screen
- Content manipulation through various devices such as cursor movement devices or finger gestures on the display
- Internet, Wi-Fi, and wireless connectivity
- Bluetooth connectivity
So what’s lacking with the current lot of devices?
- Smart phones offer an effective means for voice entry, Wi-Fi and wireless connectivity, and information interaction (cursor movement and finger gestures), but typically the form factor makes textual entry difficult, and viewing area is limited.
- Tablet devices offer a good form factor in terms of a larger viewing area, along with similar capabilities to the smart phone, but may present a bulky approach to telephone conversations without something like Bluetooth technology.
- Tablet PC’s can usually offer similar capabilities but in a bulkier form factor, and typically do not offer telephone service, or as sophisticated finger gesturing control.
- Wearable PC’s were once the rage, but that idea seems to have faded, and I doubt many physicians would be attracked to the idea!
Perhaps the problem is packaging. The smart phone probably packs all the necessary capability, but is not the best form factor for effective entry and viewing of information. The tablet and tablet PC’s are better form factors for viewing and data entry, but they do not lend themselves to effective communication.
If one were to consider splitting functionality, it could provide the best of all worlds in terms of the “iDoc.” Wireless technology enables wireless keyboard and mice, and streaming technology enables wireless displays. Such technology is already creeping into consumer products with the latest trend by Google, Amazon, and others to create internet devices that can stream movies to one’s TV. LCD TV technology already allows internet connectivity for similar purposes, and along with wireless keyboard devices can enable interactivity over the internet from one’s favorite recliner.
So why not similar technology in the physician’s office? Why not a smart phone device that handles network connectivity and communication that can then stream to larger displays, handles telephone communication through Bluetooth, and accepts input from input devices such as a keyboard and mouse? This could perhaps enable proliferation of component devices such as displays and keyboards to be spread around facilities to enhance entry and visualization, while enabling the key device to mobile and self-sufficient when the physician is away from his/her office. With proximity sensing, the device could link and unlink from devices as the physician goes about their business.
I’m all for experimentation with today’s technology. But, perhaps in a few more years’ time, a whole new crop of consumer technology will be available to apply to healthcare’s needs and truly create the “iDoc.” As usual, I welcome your perspective.
