The mobile seniors’ clinic - an innovative transition of care for frail older adults
Bibliographic record
Abstract
BACKGROUND: This study aims to evaluate the impact of Quebec's first hospital-at-home-inspired mobile Seniors' Clinic, the "Clinique des Ainés (CDA)", on frail older adults' returns to the Emergency Department (ED), mortality, and hospital Length Of Stay (LOS) and rehospitalizations. METHODS: Design: Quasi-experimental pre-post implementation cohort study. POPULATION: Patients aged ≥ 75 years admitted to the short-term geriatric unit after an ED consultation (control) or included by the CDA (intervention). OUTCOMES: return to ED (RtoED), mortality, ED & hospital LOS, and rehospitalizations. STATISTICAL ANALYSES: Multivariable regression modelling. RESULTS: Overall, 891 patients were included. At the intervention site (CDA) (n = 437), RtoED were similar at 30 (17.5% & 19.5%, p = 0.58), 90 (34.4% & 37.3%, p = 0.46) and 180 days (47.2% & 54.0%, p = 0.07) in the pre and post-implementation phases. No mortality differences were found. The hospitalization LOS was significantly shorter (28.26 and 14.22 days, p < 0.01). At 90 days, rehospitalization LOS was decreased by 8.51 days (p = 0.02) and by 6.48 days at 180 days (p = 0.03). Compared to the control site (n = 454) in the post-implementation phase, RtoED was 54% at the intervention site compared to 44.1% (p = 0.02) at 180 days. The CDA had a lower adjusted probability of mortality at 90 days compared to the control site (4.8% VS 11.7%, p = 0.03). No rehospitalization LOS differences were noted. CONCLUSIONS: The Clinique des Ainés showed effectiveness in caring for frail older patients in their homes by decreasing their hospital LOS by half and 90 days mortality risk. It was a safe care trajectory without a clinically significant increase in ED returns or mortality.

How this classification was reachedexpand
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.
