Methodology: A prospective pilot clinical trial in which 46 primary care nurses in Osakidetza will be randomly assigned to two parallel groups: experimental group and control group. Each nurse will recruit at least 1 new patient in home care with PU in stage II-III. The intervention will consist of a telematic advice from the reference nurse regarding chronic wound management in relation to a specific PU. Patients will be monitored for 8 weeks with a minimum of 4 repeated measurements of the Resvech Index 2.0. To evaluate the effectiveness of the intervention, multilevel models or linear mixed models to take into account the auto-correlation at the individual level and nurse, will be used
