Effect of a Protected Mealtime Pilot on Energy and Protein Intake in a Canadian Hospital
Bibliographic record
Abstract
Purpose: In Canada, approximately 45% of hospitalized patients are moderately or severely malnourished upon admission. The protected mealtime policy was designed to address malnutrition in institutions. This pilot study aimed to provide preliminary results examining the effect of this policy on patient energy and protein intake. Methods: A 1-group, pre–post observation design was conducted in a Canadian hospital. Pre- and post-observations included the frequency and type of interruptions, type of interrupter, and patient energy and protein intake at each meal. Results: The average number and length of interruptions decreased, and the average length of mealtime assistance provided to patients (n = 12) increased in the post-observation period. Energy and protein consumption showed a slight increase during the post-observation period. Conclusion: A protected mealtime policy may be an effective policy to address malnutrition among hospitalized Canadian adults. Further studies are warranted in Canada to determine the effects and feasibility of this policy implementation.

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.
