There've been a few digital dictation questions in the past week or so (both here and on the Main Forum) and I'm thinking this might be a good place to pool our resources and compare and contrast. I count six distinct pieces to the Internet-enabled digital dictation situation. 1. The doctor's method of dictation and brand/type of digital recorder.
2. Encryption technology.
3. Delivery to the MT.
4. Transcription and dictation playback once the MT gets the audio.
5. A way for the doctor to retrieve and print his report.
6. Online storage/search of both the dictated voice file and the finished transcription. (I mentioned this last one because some people might want to keep documents and audio files online for a little while so their doctors, not to mention other doctors in the practice, can refer to them later if necessary.)
#1 Capturing dictation: There are the various handhelds from Olympus (DS-150, 2000, and 3000), the Uher DH-10, and the ability for the doctor to dictate directly to his PC.
#2 Encryption. This is necessary! If you don't do this third parties will be able to read the patient reports and listen to the dictated audio. PGP is very good and free.
#3 Delivery of audio files, can be solved with encryption and e-mail, if the files are small enough, or with encryption and FTP if they are larger. FTP software: Send-It, WS-FTP, CuteFTP, BulletProof FTP.
#4 Playback and transcription of audio. There is the ByteScribe player, the GearPlayer, Start-Stop, PlayAll Xtra, and DSS Player Pro. There must be others out there but I can't think of any more off the top of my head.
#5 Retrieval by the doctor, can be accomplished the same way that delivery to the MT is done. You can encrypt and e-mail the files or encrypt and FTP them.
#6 Online storage. FTP will work. So will something like HyperSend.
ADDITIONAL NOTES:
* An ASP (Application Service Provider) will take care of these various pieces for you and add some features as well as streamlining, but at an additional charge.
* Most people get some amount of FTP/web space when they open an account with an Internet Service Provider like Earthlink or AOL. If you have a fast connection to the Internet and a static IP address, there is free software you can get that will turn certain directories on your computer into an FTP server. Search for WarFTP.
* Don't leave out the encryption piece!!
Okay, I'm done and out of ideas.
Please everyone add your suggestions and any additional info.
