A systematic review, meta-analysis, and meta-regression of patient education for secondary prevention in patients with coronary heart disease: impact on psychological outcomes
Bibliographic record
Abstract
BACKGROUND: Patient education is a cardiac rehabilitation core component and is associated with improvements in self-management of patients with coronary heart disease (CHD). However, the efficacy of such interventions on psychosocial outcomes and relative impact of duration is less clear. OBJECTIVES: This study aimed to assess the efficacy of patient education for secondary prevention related to behaviour change and risk factor modification on psychological outcomes in CHD patients. DESIGN: A systematic review and meta-analysis. DATA SOURCES: PsycINFO, CINAHL, Embase, EmCare, MEDLINE, PubMed, and the Cochrane Central Register of Controlled Trials were searched from inception to February 2021. ELIGIBILITY CRITERIA FOR STUDY SELECTION: Randomized controlled trials (RCTs) evaluating patient education in CHD patients, or following myocardial infarction, or revascularization compared with usual care were identified. Outcomes included depression and anxiety at <6 and 6-12 months of follow-up. RESULTS: A total of 39 RCTs and 8748 participants were included. Patient education significantly improved participants' depressive symptoms at <6 (SMD -0.82) and 6-12 months (SMD -0.38) of follow-up and anxiety level at <6 (SMD -0.90), and 6-12 months (SMD -0.32) of follow-up. Patient education also reduced the risk for having clinical depression by 35% and anxiety by 60%. Longer patient education of ≥3 months, resulted in more improvement in depressive symptoms at 6-12 months (coefficient -0.210) compared to shorter duration. CONCLUSIONS: Patient education for secondary prevention reduces anxiety and depressive symptoms in CHD patients. Regardless of intensity, longer patient education improves depression more than short duration. More information is needed on the relative impact of other intervention components. DATA REGISTRATION: PROSPERO (CRD42020200504).

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.
