Telemedicine system

The data such as photographs can be collected simply using built-in cameras installed in smart-phones that used the standard touch-screen user interface (UI) and camera installed in the iPhone3GS and iPhone4 using iOS 3.0 and iOS 5.0, respectively. Subjects were instructed to transmit the photographs of the wounds then investigator performed the photography in such a manner that the size of pressure ulcer should be automatically measured based on a 1 cm x 1 cm-sized indicator on the screen.

1. Data collection

   • The measurement of the size of pressure ulcer
   • Medical examination;the degree of recovery of pressure ulcer

2. Remote physician monitoring

   - The patient data was transmitted from the smart-phone to the website via open application programming interface (API)

3. Prescription

4. Data analysis - One plastic surgeon, one Wound Ostomy Continence Nurse(WOCN) and one researcher grossly examined the wound sites of each patient and assessed the pressure ulcer using the revised PSST based on a 4-6 point scale.
