APACHE II Death Risk and Length of Stay in the ICU Are Associated With Pressure Injury in Critically Ill Patients
Bibliographic record
Abstract
BACKGROUND: The aim of this study was to identify factors associated with pressure injury (PI) occurrence in critically ill patients. This was a retrospective cohort study conducted at a mixed intensive care unit (ICU). METHODS: Univariate analysis and logistic regression were used to identify which variables are associated with PI. RESULTS: Twenty-one (15%) of 142 patients developed PI. The median and the range of the variables in the groups without and with PI were as follows: Braden scale risk score, 13 (8 - 20) and 10 (8 - 14) points, respectively; Acute Physiology and Chronic Health Evaluation II (APACHE II) death risk, 39% (2 - 97%) and 75% (26 - 96%), respectively; and length of stay in the ICU, 4 (2 - 36) and 16 (5 - 29) days, respectively. The socio-demographic variables included in the logistic regression were age (P = 0.09), Braden scale risk score (P = 0.0003), APACHE II death risk (P < 0.0001), length of stay in the ICU (P < 0.0001) and reason for ICU admission (P = 0.09). Only APACHE II death risk and length of stay in the ICU presented significant differences; the odds ratios were 1.05 and 1.25, respectively, and the 95% confidence intervals were 1.01 - 1.09 and 1.12 - 1.39, respectively. CONCLUSION: APACHE II death risk and length of stay in the ICU are probably associated with PI occurrence in the study population.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
