ICU Admission Preferences in the Hypothetical Event of Acute Critical Illness: A Survey of Very Old Norwegians and Their Next-of-Kins
Bibliographic record
Abstract
OBJECTIVES: To explore older patients' ICU admission preferences and their next-of-kins' ability to predict these preferences. DESIGN: Self-administered survey. SETTING: Three outpatient clinics, urban tertiary teaching hospital, Norway. PATIENTS: Purposive sample of outpatients 80 years old or older regarded as potential ICU candidates and their next-of-kins. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We asked about the patients' ICU admission preferences in three hypothetical scenarios of acute critical illness. Next-of-kin respondents were asked to make a proxy statement regarding the older respondents' wishes regarding ICU admission. For each treatment choice, all respondents could provide their level of confidence. Additionally, we sought to identify demographic and healthcare-related characteristics that potentially influenced ICU admission preferences and proxy accuracy. Of 202 outpatients 80 years old or older, equal proportions opted for (39%; CI, 33-45%) and against (40%; CI, 34-46%) ICU admission, and one in five (21%; CI, 17-26%) did not wish to engage decision-making. Male gender, religiosity, and prior ICU experience increased the likelihood of older respondents opting for ICU admission. Although next-of-kins' proxy statements only weakly agreed with the older respondents' true ICU admission preferences (52%; CI, 45-59%), they agreed with the next-of-kins' own ICU admission preferences (79%; CI, 73-84%) to a significantly higher degree. Decisional confidence was high for both the older and the next-of-kin respondents. CONCLUSIONS: In this purposive sample of Norwegian potential ICU candidates 80 years old or older, we found substantial variation in the ICU admission preferences of very old patients. The next-of-kins' proxy statements did not align with the ICU admission preferences of the older respondents in half of the pairs, but next-of-kins' and older respondents' confidence levels in rendering these judgments were high.

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; a candidate call from one teacher head, not a consensus.
