Effectiveness of Installing Overhead Ceiling Lifts
Bibliographic record
Abstract
The effectiveness of replacing floor lifts with mechanical ceiling lifts was evaluated in the extended care unit of a British Columbia hospital. Sixty-five ceiling lifts were installed between April and August 1998. Injury data were abstracted from injury reports for all staff musculoskeletal injuries (MSI) occurring in the unit during a 3 year period prior to installation and a 1.5 year follow up period. Descriptive statistics were calculated for injuries pre- versus post-installation. Rates were calculated as number of injuries per 100,000 worked hours. Rates for three pre- and three post-installation intervals were compared using Poisson regression. The rate of MSI caused by lifting/transferring patients was significantly reduced (58% reduction, p = .011) after installation, but rates of all MSI and MSI caused by repositioning did not statistically decline (p > .05). Further follow up is necessary to determine whether or not ceiling lifts also can be effective for decreasing injuries related to repositioning patients on this unit.

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.
