2792 Hospital outcomes following hip fracture in older adults: does frailty matter?
Bibliographic record
Abstract
Abstract Objectives Older adults hospitalised with a hip fracture are at risk for adverse health outcomes depending on their level of frailty. This study examined how frailty levels prior to admission impacted length of stay (LOS), requirement for alternative level of care (ALC), returning home post-discharge, and mortality. Methods A random sample was generated from all hip fracture patients aged 65 and older admitted to a Level One Trauma Centre in New Brunswick, Canada from 2015–2019. This sample had their frailty level determined retrospectively using the Pictorial Fit-Frail Scale and the patients’ hospital electronic health record. Results Our study included 189 patients (mean age: 83.2 ± 8.2, 73.0% female), representing 91 not frail to mildly frail (48.2%; NF-MF), 32 moderately frail (16.9%; ModF), and 66 severely frail (34.9%; SF) patients. The ModF patients had a longer LOS (median: 20.0 days, IQR = 22.5) compared to NF-MF patients (median: 11.0 days, IQR = 10.0, p = 0.039, Kruskal-Wallis test) and SF patients (median: 8 days, IQR = 5.5, p < 0.0001, Kruskal-Wallis test). More ModF patients (56.3%) required an ALC stay in acute care compared to NF-MF (30.8%) and SF (28.8%) patients (p = 0.016, Chi-square test). More SF patients (28.8%) died in hospital or within six months post-discharge compared to NF-MF (8.8%) patients (p = 0.005, Chi-square test). Logistic regression revealed that both NF-MF (OR = 8.11, 95% CI: [3.12–21.06], p < 0.001) and ModF (OR = 5.18, 95% CI: [0.85–0.95], p = 0.007) patients had greater odds of returning home compared to SF patients when accounting for sex, age, and time to surgery. Conclusions A patient’s level of frailty prior to hospital admission impacts various health outcomes following a hip fracture and may provide helpful information for guiding treatment as well as discussions about health care.

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.
