Brief Summary

This study is a retrospective record review conducted among adult patients hospitalized in the intensive care unit of a tertiary hospital between October 10, 2020, and October 10, 2025. The aim of the study is to predict the risk of pressure injury development using demographic, clinical, laboratory, and nursing care-related variables by applying multiple data mining algorithms. No intervention, treatment, or patient contact will occur. All data will be extracted from existing electronic and paper-based medical records and will be fully anonymized prior to analysis. The study poses no risk to participants and will be conducted with approval from the institutional review board or ethics committee.

Outcome Measures

Primary Outcomes (1)

• Prediction accuracy of pressure injury development

  The primary outcome is the predictive accuracy of data mining algorithms in identifying the risk of developing pressure injury among patients hospitalized in the intensive care unit (ICU). Accuracy metrics such as the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, precision, recall, and F1-score will be calculated using retrospective medical record data.

ICU Patient Cohort

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

Adult patients aged 18 years and older who were hospitalized in the intensive care unit (ICU) of a tertiary public hospital between October 10, 2020, and October 10, 2025 will be included in this retrospective observational study. The study population includes patients with a minimum ICU stay of 24 hours and complete, accessible electronic or paper-based medical records. Patients with missing or inconsistent medical record data or with a pressure injury diagnosed before or at the time of ICU admission will be excluded. All data will be collected retrospectively from existing medical records.

You may qualify if:

• Patients hospitalized in the intensive care unit between October 10, 2020, and \* October 10, 2025
• Adult patients aged 18 years and older
• Length of intensive care unit stay of at least 24 hours
• Availability of complete and accessible electronic or paper-based medical records

You may not qualify if:

• Patients younger than 18 years
• Intensive care unit stay shorter than 24 hours Incomplete, missing, or inconsistent electronic or paper-based medical records
• Presence of a pressure injury diagnosed before or at the time of intensive care unit admission
• Inability to extract pressure injury-related data from medical records
