A prospective study of early ambulation 90 minutes post-left heart catheterization using a retrospective comparison group.
Bibliographic record
Abstract
BACKGROUND: Despite a trend toward a reduction in bedrest time after left heart catheterization (LHC) in many Canadian centres, an evidence-based standard of practice has not been established. Canadian bedrest times range from two to four hours post-LHC. Two recent prospective non-randomized studies (n = 1,000) indicate safety of ambulation at 60 and 90 minutes post-LHC. PURPOSE: The purpose of this study was to determine safety of ambulating patients at 90 minutes post-LHC sheath removal compared to the current practice of ambulation at three to four hours post-sheath removal. DESIGN: The study was a prospective non-concurrent design with a retrospective control. METHOD/SAMPLE: Retrospective data from the APPROACH database and chart reviews were analyzed for a period of six months for the control group on the traditional three- to four-hour ambulation protocol (n = 402). Prospective data were gathered for six months for the experimental group (n = 193). RESULTS: There was no difference in complication rates for the two groups. CONCLUSIONS: The results suggest that early ambulation for selected patients at 90 minutes is safe and has the potential to increase both patient comfort and quality of care.

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.
