How accurate are chronic wound assessments using interactive video technology?

This project examined the accuracy of chronic wound assessments made using an interactive, video telecommunications system (Teledoc 5000, NEC America, Inc., Irving, TX) by comparing a nurse expert's in-person wound assessments with wound assessments made from taped Teledoc sessions. Wound assessments determined the absence or presence of nine wound characteristics instrumental in guiding treatment (e.g., tunneling, undermining, granulation tissue, necrotic tissue, epithelial tissue, purulent exudate, erythema, edema, induration). A sample of 13 paired wound observations was analyzed. The accuracy of the Teledoc technology was examined by calculating the amount of agreement between the in-person assessments and the taped Teledoc assessments for each of the nine characteristics. Agreement for eight of the nine wound characteristic exceeded 75%, suggesting this telehealth medium does not alter wound assessment data, which are essential in guiding treatment decisions. In addition to connecting the remotely based nurse with nursing expertise to improve patient care, telehealth technology seemed to increase the remotely-based nurses' knowledge of wound assessment and treatment as well.

A nursing application of telecommunications. Measurement of satisfaction for patients and providers.

Consumer and provider satisfaction is key to the continued use and expansion of telehealth technology. This pilot study compared satisfaction of providers and patients with wound consultations done in person with those done via real-time interactive video technology. Eleven telehealth consultations with a nurse expert were immediately followed by an in-person consultation with a second nurse expert. Satisfaction questionnaires were administered to patients, referring nurses, and the consultant nurse expert following both the in-person consultation and the telehealth consultation. The referring nurses (100%) were satisfied with both the telehealth and in-person consultations, noting the ability to provide better care for their patients. The patients (55%) were "very satisfied" with the telehealth consultations versus 40% satisfied with the in-person consultations. Difficulty in hearing for the patients was equal in both groups, which resulted in changes in the consultation process. The patients' difficulty in seeing the telehealth consultant was addressed through larger screens and strategic positioning to provide easier viewing for the patient and providers. The telehealth nurse consultant was satisfied overall but had some difficulty communicating. This pilot study helped provide useful information for both the telehealth and in-person consultations.
