Telephone Follow-Up by Nurse After Total Knee Arthroplasty
Bibliographic record
Abstract
BACKGROUND/PURPOSE: Because of shorter hospitalizations, patients now have to take responsibility for their recovery period at a very early stage. We evaluated the effects of structured, nurse-managed telephone follow-up (TFU) after discharge from the hospital following total knee arthroplasty (TKA). METHOD/DESIGN: The design was a single-center, unblinded, parallel-group randomized clinical trial. The primary outcome was self-reported physical function according to the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index. Secondary outcomes were stiffness and pain according to the WOMAC Index; health-related quality of life, measured with the Medical Outcomes Study Short Form (SF-36); general self-efficacy, measured with the General Self-Efficacy Scale; and number of acute visits to the orthopaedic outpatient clinic. In total, 117 patients were randomized to 2 groups: an intervention group receiving TFU 4 and 14 days after discharge in addition to conventional treatment, and a control group receiving conventional treatment. The TFUs were structured by key subjects for health status, as defined by the VIPS model (the Swedish acronym for the concepts of Well-being, Integrity, Prevention, and Safety). The effect was measured 1 and 3 months postsurgery. RESULTS: No significant effects on physical function in the disease-specific WOMAC Index were identified. However, significant differences in scores were identified in favor of the intervention group on general self-efficacy (p = .014) and physical function (p = .031), measured with the Medical Outcomes Study Short Form 1 month after TKA, but this effect was not seen at 3 months. A positive improvement in several dimensions of health status and health-related quality of life was identified in favor of the intervention group, but patients who had TFU had more unscheduled visits to the outpatient clinic. CONCLUSIONS: Telephone follow-up did not improve physical function compared with conventional treatment, as measured with the WOMAC Index. A short-term effect was identified, improving general self-efficacy and physical function as dimensions of health-related quality of life.

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.
