A pilot trial of a home-based peer support program after coronary artery bypass graft surgery
Bibliographic record
Abstract
Coronary artery bypass graft (CABG) surgery is performed more frequently on individuals who are older and sicker than in previous years. Increased patient acuity and reduced hospital length of stays leave individuals ill prepared for their recovery following discharge. Individuals experience pain, functional impairment and depressive symptoms; which predispose them to adverse events and impaired HRQOL. The objectives of this pilot trial were to test the feasibility of all procedures, specifically to determine: (1) an estimate of patient and peer recruitment rates, (2) peer compliance and dose of the intervention, (3) peer satisfaction with orientation, (4) peer support activities offered to patients, and (5) patients' satisfaction with peer support. Additionally, exploratory research questions were used to determine indicators of the effects of peer support on HRQOL, pain, pain-related interference with activities, function, depressive symptoms, and enrolment in cardiac rehabilitation.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
