This study evaluates the use of the Teler system tool in assessing the effectiveness of dressings used in patients with fungating malignant wounds. The Teler system of clinical evaluation was adapted for the study. This system measures outcomes for the key variables of symptom control, dressing performance and impact of the wound on the patient's daily life by tracing change or lack of change. Data are presented from one patient, and summarised data from 16 additional patients, relating to number of dressing changes, control of exudate and dressing fit.
