Barriers to Cardiac Rehabilitation Use in Canada Versus Brazil
Bibliographic record
Abstract
In Brief PURPOSE: Despite its well-established benefits, cardiac rehabilitation (CR) is greatly underutilized globally. Barriers to its utilization have been identified in high-income countries. Given the growing epidemic of noncommunicable diseases in low- to middle-income countries, the identification of barriers to use of these low-cost interventions is warranted. The aim of this study was to describe and compare barriers to CR use in Brazilian and Canadian cardiac outpatients. METHODS: Two cardiac samples consisting of 237 Brazilian (recruited from 2 CR centers in southern Brazil) and 1434 Canadian (recruited from 11 community and academic hospitals in Ontario) outpatients were compared cross-sectionally. Barriers were assessed by using the Cardiac Rehabilitation Barriers Scale, psychometrically validated in English and Portuguese. Mann-Whitney U tests were used to compare barriers between samples. RESULTS: Overall, 139 (58.6%) Brazilian and 779 (54.3%) Canadian respondents were enrolled in CR. The mean total barriers score for Brazilian respondents was 1.71 ± 0.63, and 2.37 ± 1.0 (P < .01) for the Canadians. For 17 of 21 barriers, Canadians reported significantly greater barriers than Brazilians (P < .02). As their greatest barriers, Canadians rated already exercising at home or in the community and personal travel, while Brazilians identified distance to and cost of the CR program. CONCLUSION: Despite the significantly lower availability of CR in Brazil and the universal health care system in Canada, cardiac outpatients in Canada perceived significantly greater CR barriers. Arguably, however, these barriers were more modifiable. This study aimed to describe and compare barriers to cardiac rehabilitation use in 2 samples consisting of Brazilian and Canadian outpatients. The Cardiac Rehabilitation Barriers Scale was used, and the results indicated that cardiac outpatients in Canada perceived significantly greater cardiac rehabilitation barriers than the Brazilians.

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.
