A Randomized Controlled Trial of an Individualized Preoperative Education Intervention for Symptom Management After Total Knee Arthroplasty
Bibliographic record
Abstract
Pain and nausea limit recovery after total knee arthroplasty (TKA) patients. The aim of this study was to determine the effect of a preoperative educational intervention on postsurgical pain-related interference in activities, pain, and nausea. Participants (n = 143) were randomized to intervention or standard care. The standard care group received the usual teaching. The intervention group received the usual teaching, a booklet containing symptom management after TKA, an individual teaching session, and a follow-up support call. Outcome measures assessed pain, pain interference, and nausea. There were no differences between groups in patient outcomes. There were no group differences for pain at any time point. Respondents had severe postoperative pain and nausea and received inadequate doses of analgesia and antiemetics. Individualizing education content was insufficient to produce a change in symptoms for patients. Further research involving the modification of system factors affecting the provision of symptom management interventions is warranted.

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.
