Primary Health Care: Concept and Challenges for its Implementation
Bibliographic record
Abstract
Since the Alma-Ata (WHO) declaration of primary health in 1978 and the Ottawa Charter for Health Promotion in 1986, the concept of primary health care has become central to the definition of health care. Public health professionals have generally embraced the WHO's broadened definition of primary health care and have encouraged governments to reformulate national health policies to reflect this new orientation. However, although the rhetoric of primary health care has expanded beyond the traditional focus on general practitioners and hospitals to include a focus on community-based health care, intersectoral collaboration and community participation, a review of experiences in America and Europe suggests that national health systems are still struggling to implement this broader notion of health care.

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.
