100 patients suffering from pressure ulcer
100 subjects were having at least one wound of pressure ulcer (74 men and 26 women) middle-aged (55.5±20 years) and were recruited from many services of three University Regional hospitals of Tunisia.

|
213 healthy subjects
213 healthy subjects (125 men and 88 women) middle-aged (51.5±17 years).
Although, healthy individuals, were included as controls, followed in the outpatient services of the University Hospital Farhat Hached and they considered clinically free of pressure ulcer and tissue necrosis.

Nutritional status
Zeitfenster: 3 hours
|
- Nutritional Risk Index (NRI) was originally derived from the serum albumin concentration and the ratio of present to usual weight [NRI = (1.489
x albumin, g/L) + (41.7 x present weight/ideal body weight)] and categorized as follows: severe risk (NRI < 83.5), moderate risk (83.5 < NRI < 97.5) and no risk (NRI > 97.5).

Nutritional risk
Zeitfenster: 3 hours
|
- Prognostic Inflammatory and Nutritional Index (PINI) is a simple clinical [PINI = AAG x CRP / albumine x prealbumin] and classificated as follows: normal (1<PINI score <10), mild malnutrition (11<PINI score<20), severe malnutrition (21<PINI score<30) and risk for death when PINI score >30. These scores gained in popularity as it uses an objective rather than subjective measurements to determine nutritional risk in hospitalized patient populations. |

A microbiological diagnosis
Zeitfenster: 3 days
|
The bacterial colonization of a wound is a recognized detrimental factor in the multifactorial process of wound healing. wound per patient suffering from pressure ulcer was cultured by swab to determine the bacterial species of the infection and helps guide antibiotic therapy. The representative sample is collected before topical or systemic antibiotics are initiated and pain assessment should be conducted prior to wound procedures such as dressing changes and debridement. Bacterial swabs provide information on the predominant flora. |
