Access to Ontario Midwifery Care by Neighbourhood-Level Material Deprivation Quintile, 2006–2017: A Retrospective Cohort Study
Bibliographic record
Abstract
Objective: To describe access to Ontario midwifery care based on socio-economic status.Design: Two retrospective cohort studies.Setting: Ontario, Canada.Participants: (1) All Ontario midwifery billable courses of care discharged between April 1, 2006, and March 31, 2017 (N = 187,009), and (2) all Ontario residents who gave birth (≥ 20 weeks) in Ontario between April 1, 2012, and March 31, 2017 (N = 699,843). Data Sources: The Ontario Midwifery Program Legacy Database and the Better Outcomes Registry & Network’s Ontario perinatal registry.Measurements and Findings: We used residential postal codes to assign socio-economic status quintiles, using the Ontario Marginalization Index’s material deprivation measure. Between 2006 and 2017, the proportion of midwifery clients in the two least-marginalized quintiles was consistently greater than the proportion of midwifery clients in the two most-marginalized quintiles. Between 2012 and 2017, physicians cared for a larger proportion of people in the most-marginalized quintile than midwives, while midwives cared for a larger proportion of people in the least-marginalized quintile. Key Conclusions: People of low socio-economic status in Ontario are less likely to receive midwifery care than people of high socio-economic status. There was little change in this pattern over an 11-year period from 2006 to 2017.Implications: Efforts to reduce inequities in access to midwifery care should be prioritized and will require a multi-pronged approach that is supported by practicing midwives, government, midwifery stakeholder organizations, and other health care professionals.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
