Implementation of mifepristone medical abortion in Canada: pilot and feasibility testing of a survey to assess facilitators and barriers
Bibliographic record
Abstract
BACKGROUND: Direct primary care provision of first-trimester medical abortion could potentially address inequitable abortion access in Canada. However, when Health Canada approved the combination medication Mifegymiso® (mifepristone 200 mg/misoprostol 800 mcg) for medical abortion in July 2015, we hypothesized that the restrictions to distribution, prescribing, and dispensing would impede the uptake of this evidence-based innovation in primary care. We developed and pilot-tested a survey related to policy and practice facilitators and barriers to assess successful initiation and ongoing clinical provision of medical abortion service by physicians undertaking mifepristone training. Additionally, we explored expert, stakeholder, and physician perceptions of the impact of facilitators and barriers on abortion services throughout Canada. METHODS: In phase 1, we developed a survey using 2 theoretical frameworks: Greenhalgh's conceptual model for the Diffusion of Innovations in health service organizations (which we operationalized) and Godin's framework to assess the impact of professional development on the uptake of new practices operationalized in Légaré's validated questionnaire. We finalized questions in phase 2 using the modified Delphi methodology. The survey was then tested by an expert panel of 25 nationally representative physician participants and 4 clinical content experts. Qualitative analysis of transcripts enriched and validated the content by identifying these potential barriers: physicians dispensing the medication, mandatory training to become a prescriber, burdens for patients, lack of remuneration for mifepristone provision, and services available in my community. To assess the usability and reliability of the online survey, in phase 3, we pilot-tested the survey for feasibility. RESULTS: We developed and tested a 61-item Mifepristone Implementation Survey suitable to study the facilitators and barriers to implementation of mifepristone first-trimester medical abortion practice by physicians in Canada. CONCLUSIONS: Our team operationalized Greenhalgh's theoretical framework for Diffusion of Innovations in health systems to explore factors influencing the implementation of first-trimester medical abortion provision. This process may be useful for those evaluating other health system innovations. Identification of facilitators and barriers to implementation of mifepristone practice in Canada and knowledge translation has the potential to inform regulatory and health system changes to support and scale up facilitators and mitigate barriers to equitable medical abortion provision.

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.
