Barriers to accessing weight-loss interventions for patients with class II or III obesity in primary care: a qualitative study
Bibliographic record
Abstract
BACKGROUND: Over 1 million Canadians have class II or III obesity; however, access to weight-loss interventions for these patients remains limited. The purpose of our study was to identify the barriers to accessing medical and surgical weight-loss interventions from the perspectives of 3 groups: family physicians, patients who were referred for weight-loss intervention and patients who were not referred for weight-loss intervention. METHODS: Between November 2017 and May 2018, we conducted a qualitative exploratory research study using focus groups with family physicians and interviews with patients with class II or III obesity from 1 region in southern Ontario. We conducted a thematic analysis to identify emergent themes and used the barriers to change theory to classify the similarities and differences between the perspectives of family physicians, referred patients and nonreferred patients in first- and second-order barriers. RESULTS: Seventeen family physicians participated in 7 focus groups (1-4 participants/group), and we interviewed 8 referred patients and 7 nonreferred patients. We identified lack of resource supports, logistics and lack of knowledge about weight-loss interventions as first-order barriers to change, and lack of knowledge about root causes of obesity, lack of patient readiness for change and family physicians' perceptions about surgical weight loss as second-order barriers to change. Family physicians and patients had similar perceptions regarding lack of resource supports in the community, logistical issues, family physicians' lack of knowledge regarding weight-loss interventions, patients' lack of motivation and family physicians' perceptions of bariatric surgery as being high risk. They differed regarding the root cause of obesity, with family physicians attributing obesity to multiple extrinsic and intrinsic causes, whereas patients believed obesity was largely due to intrinsic causes alone. INTERPRETATION: It is important to address first- and second-order barriers to accessing weight-loss interventions through continuing professional development activities for family physicians to help ensure effective and timely treatment for patients with class II or III obesity and related comorbidities.

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.
