Recruitment & Eligibility

• Status: Ongoing
• Sex: All
• Target Recruitment: 362

Inclusion Criteria

1. Users are subject to nursing assessment over 18 years of age
2. Nursing assessment performed in the first 24 hours after admission
3. Expected hospital stay of more than 48 hours
4. Agree to participate in the study and sign the Informed Consent
5. Nursing assessments including the use of the instruments under study (Barthel index, Braden index, Downton scale and VALENF Instrument)

Exclusion Criteria

Users who come from transfers from other units of the same hospital and other hospitals will be excluded, since their care process is still in progress and their admission assessment does not correspond to that of the hospital.

Study & Design

• Study Type: Observational
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Diagnostic accuracy will be analyzed through the sensitivity, specificity and positive and negative predictive values of the VALENF Instrument to detect patients at risk of pressure injuries, falls and functional loss using the Barthel, Braden and Downton indices as reference tests within the first 24 hours after admission

Secondary Outcome Measures

Name	Time	Method
The cumulative incidence and the period incidence of pressure injuries, falls and patients with functional loss will be estimated by units and globally. A survival analysis will be carried out considering the appearance of pressure injury, falls or functional loss as dependent variables and the other study variables as independent variables.<br>Finally, the VALENF Instrument cut-off points will be established to detect the risk of pressure injuries, falls, and functional gain through simple linear regressions with the original instruments, cluster analysis to categorize patients, and analysis of the area under the ROC curve.
