The main part of the study is a retrospective analysis of 200 reports concerning patients with skin wounds and injuries :

• 50 consecutive patient reports dealing with skin lacerations
• 50 consecutive patient reports dealing with skin abrasions
• 50 consecutive patient reports dealing with skin burns
• 50 consecutive patient reports dealing with leg ulcers

The study comprises a complementary prospective segment, consisting of data collection from patients and from care delivery personnel, threw short interviews, in order to assess the validity of the retrospective recording on reports.

The retrospective part of the study consists of data collection regarding care delivered to heal skin injuries.

For procedures performed in the emergency department (wound care, dermabrasions and burns), the main source of collection data will be the computerized emergency files that are completed by the doctors and that meet our objectives. For the care of leg ulcers, the main source of collection are records from vascular medicine consultations, and will be represented by the care files that are filled in by the nurses during the consultation.

In each of the four sections of the survey (wounds, dermabrasions, burns and leg ulcers), 50 "consecutive and correctly completed" acts will be included and will be collected.

Incomplete files (missing data on the procedures performed and/or treatments administered) will be replaced by the following ones in reverse chronological order. Inclusion will start with the most recent files and extend to the oldest ones. When the investigators have doubts about the understanding and correct interpretation of the information in the source files, they will discuss them with the careproviders, on an ad hoc basis and during the scheduled structured interviews.

The prospective part of the study consists of short guided interviews with patients (10-minute conversation with specific formated questions) and with care providers (15-minute conversation). The objective of the interviews is to validate, complete and/or correct the information collected threw patient reports.
