A preliminary study of the, feasibility of wound telecare ford the elderly

We have developed a method for remote wound assessment in the elderly. Wound images were taken with a digital camera at a resolution of 640 x 480 pixels. JPEG compression was then used to produce images of about 100 kByte. Selected clinical data were transmitted by email, together with standardized digital images of wounds. The remote physician then read the clinical data and viewed the digital images on a 38 cm colour display monitor, at a resolution of 800 x 600 pixels, in 16-bit colour, using standard software. Three elderly inpatients with pressure sores or leg ulcers had both, bedside and remote examinations, by different physicians. The diagnosis and therapeutic recommendations proposed after each of the two examinations were compared qualitatively. There was reasonable agreement between the two physicians in the assessment of wound size, anatomical classification, wound bed and status of infection. However, the lack of palpation represented a major limitation to remote wound assessment, despite the use of probes to delineate the depth of any opening in the wound bed.
