Prevalence and Symptoms of Delirium Superimposed on Dementia
Bibliographic record
Abstract
Delirium is a frequent syndrome among patients who are elderly. People who are older with cognitive impairment who are institutionalized are at increased risk of developing delirium when hospitalized. In addition, their prior cognitive impairment makes detecting their delirium a challenge. This study goal was to describe the effect of severity of prior cognitive impairment on delirium prevalence and symptom presentation among patients who were older and were newly admitted to an acute care hospital. A total of 104 were included in this descriptive study and screened for delirium. The results showed that the prevalence of delirium increased according to the severity of the patients' prior cognitive impairment. Except for disorganized thinking, all symptoms of delirium were similar among patients with mild, moderate, and severe prior cognitive impairment. The study concluded that training nurses to recognize subtle changes in mental status among those patients who were older with prior cognitive impairment may prevent the underdetection of delirium.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
