Title: Olive Oil's Cream Effectiveness in Prevention of Pressure Ulcers in Immobilized Patients in Primary Care.A Cluster Randomized Clinical Trial.
Brief Summary: Pressure ulcers (UPP) represent an important sanitary problem affecting mostly elderly immobilized persons, increasing the burden of care to professionals in the health system, as well as pharmaceutical spending. There are studies of the effectiveness of various products in the prevention of the UPP, most made in hospitals and using fundamentally composed based on oily hyperbecome oxygenated acids (AGHO).

There do not exist studies realized specifically with cream of olive oil.

AIMS:

Principal: To verify the efficiency of a new intervention of UPP's prevention in immobilized patients consisting in the application of cream of olive oil. Secondary: To evaluate the cost - efficiency of this new intervention opposite to AGHO's application.

To value the degree of satisfaction of the patient and his keeper with regard to the use of cream of olive oil.

METHODOLOGY DESIGN: clinical Test randomized with two parallel branches. AREA: Population consultant of the health centers in the province of Malaga. SUBJECTS OF STUDY: Patients immobilized at the risk of developing UPP. INTERVENTION: Administration of cream of olive oil to the group of intervention and AGHO's administration to the group control. Follow-up for one year. VARIABLES. Principal variable: UPP's appearance. Secondary: Demographic and clinical data, presence of technical supports, information of the caragiver and questionnaire of satisfaction. STATISTICAL ANALYSIS: Test. Exact of Fischer. Odds's calculation ratio. Shapiro-Wilk's test. Parametric test t- student or test U of Mann-Whitney. Reason of the increase cost efficiency (ICER). Logistic regression model multivariant.


Options:
A: * Major trauma patients and/or critically ill patients (e.g. with cardiac arrest) admitted to the emergency department and being transferred and/or admitted directly to a surgical or internal ICU
* Being at "high" or "very high" PU risk according to the Charité PU prevention standard:

  - Category 3 (= partly care dependent/limited mobility in bed), 4A (= care depended, limited mobility in bed), 4B (= totally immobile) according to the Jones classification modified by Charité
* Expected minimum length of stay at least three days
* Informed consent (or by legal representative)
B: Inclusion criteria:

* Patients with nursing diagnosis "risk of impaired skin integrity. "To determine this risk assessment tool we will use as the Braden scale. We will include only patients immobilized with increased risk of pressure ulcers (score less than or equal to 16).
* Patients with malnutrition or suspected malnutrition. To determine this state as an instrument we will use Mini Nutritional Assessment Scale "MNA" (score 10 points or less)
* Over 18 years.

Exclusion criteria:

* Patients refusal to participate in the study.
* Moved (patient no habitual residence in the health center where they make the study).
* Patients with plans to be out of the study area during the monitoring year.
* Hospitalized during the uptake phase of the sample
* Patient-terminal.
* Patient with the presence of pressure ulcers.
C: Inclusion Criteria:

* 18 years of age or older,
* Having written permission from relatives and / or him / her,
* A nasogastric tube is inserted after admission to the Intensive Care Unit,
* In accordance with the literature reporting that nasogastric tube-induced pressure injuries occur on the second day after nasogastric tube, patients with a planned nasogastric tube stay of at least 48 hours will be included.

Exclusion Criteria:

* Do not sign the informed consent form,
* A nasogastric tube inserted during admission to the Intensive Care Unit,
* If there is irritation or wound in the nasal mucosa, nasal arch, nasal wings and surrounding tissue before the nasogastric tube is inserted,
* A rash that does not fade with pressure on the nasal arch, nose wings and surrounding tissue before the nasogastric tube is inserted,
* Nasogastric tube position change is contraindicated.
* Nasal intubation is applied before the nasogastric tube is inserted,
* If nasogastric tube stay is planned to be shorter than 48 hours, patients will not be included.
D: Inclusion Criteria:

* Patients at risk to develop Pressure Ulcer (Braden scale \<17)
* without sacrum Pressure Ulcer
* Patients or legal guardians who give their consent to take part in the study

Exclusion Criteria:

* Patients with known allergy to the product being tested or dermatological diseases that prevent the use of topical products
