Abstract
The prevalence of diabetes continues to rise, making inpatient management of diabetes an increasingly relevant issue. In teaching hospitals such as those affiliated with the University of Calgary, inpatient management of diabetes is often the responsibility of learners including residents and medical students. Several studies have demonstrated that learners lack knowledge and confidence in inpatient insulin management. To improve the way learners are taught about inpatient insulin titration, we sought to elucidate what contextual factors and mechanisms of an educational intervention are more likely to improve glycemic outcomes, and what factors, both conscious and subconscious, learners consider when making decisions about insulin titration. To determine the contextual factors and mechanisms of successful diabetes educational interventions, we conducted a realist synthesis. After analysing 21 studies, we found that interventions that improve the insulin prescribing process are necessary but not sufficient to improve glycemic outcomes. In-person, group, prescriber-specific interventions with a reinforcing intervention are more likely to be successful. To study the factors that learners consider when titrating insulin, we conducted a mixed methods study using a case-based survey loosely modelled on script concordance testing. We found that medical students prescribed insulin with greater concordance with staff endocrinologists than residents, yet residents had more confidence than medical students in their prescribing practices. Overall, the residents prescribed larger doses of insulin. The residents were susceptible to the subconscious influence of the seniority of the nurse asking for an insulin dose, yet the medical students were not. Both groups of learners prescribed more insulin in the presence of ketones and less when the patient had hypoglycemia unawareness. Residents prescribed less insulin when patients had T2DM compared to T1DM and medical students prescribed more when the blood sugar crossed the 20mmol/L threshold. We concluded that patient, prescriber, and systems factors ultimately influenced insulin prescribing practices. Overall, we concluded that a successful educational intervention to improve inpatient glycemic control would likely need to address prescribing practices in a prescriber-specific fashion and be followed with a reinforcing intervention. We proposed that medical students and residents may need different teaching methods to address possibly different cognitive processing methods.

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 it
