The A1c That Won't Move
Ms. Tran, 46, has type 2 diabetes (A1c 10.4%), obesity (BMI 38), hypertension, and a history of one depressive episode five years ago. She attends every appointment, fills her metformin and insulin reliably, and her glucose log shows fasting readings of 160-200. She works night shifts as a hospital aide and eats one large meal after her shift. She says, 'I'm doing everything right and nothing works. Maybe I'm just broken.' She has stopped checking her glucose on work days. She has not seen a behavioral health provider since her depression episode. PHQ-2 is positive. She has no transportation on weekends and no childcare for her two children on weekdays.
1. What is your differential for the stalled A1c, and how do you prioritize?
Read the worked answer
Do not accept 'nonadherence' - she fills prescriptions and attends visits. Consider:
- Circadian/night-shift mismatch: one large post-shift meal, altered cortisol and insulin sensitivity at night, and a dosing schedule built for a day-shift life can produce high fasting glucose despite adherence.
- Depression: positive PHQ-2, prior episode, and the language 'maybe I'm just broken' suggest low mood driving self-care fatigue (stopped checking on work days).
- Regimen fit: insulin timing may not match her sleep/eat pattern; fasting 160-200 suggests basal insulin or metformin dosing is inadequate for her physiology.
- Social barriers: no weekend transport, no weekday childcare - these block the very visits and education that would help.
Prioritize depression screening (full PHQ-9) and regimen-timing review together, because mood and schedule are the two modifiable drivers she can act on. Chasing adherence harder would be both wrong and alienating.
2. Design a plan that fits her actual life.

Anchor changes to her real schedule and constraints:
- Meal/insulin timing: work with her (and prescriber) to align basal insulin and the large post-shift meal - e.g., shift the meal earlier or adjust timing so the dose matches when she eats and sleeps.
- Glucose monitoring: make it low-burden on work days - check at one consistent point (e.g., before the post-shift meal) rather than multiple times she won't do.
- Behavioral health: refer for depression treatment; offer telehealth to work around transport and childcare. Frame it as treating a condition, not a character flaw.
- Access: weekend transport and weekday childcare are real barriers - connect to transportation benefits and childcare resources rather than scheduling around them.
- Language: replace 'you need to try harder' with 'your schedule and your mood are working against you; let's fix those.'
Reasoning standard: the plan must be feasible within her constraints, or it is not a plan - it is a wish.
3. She says, 'Maybe I'm just broken.' How do you respond, and why does it matter clinically?
Read the worked answer
Respond directly and without minimizing: reflect that she has been working hard and still seeing high numbers, name that this is exhausting, and separate her worth from her glucose. Then connect it to action: 'Feeling broken is a symptom worth treating - and it may be part of why the numbers won't move.'
Why it matters clinically: that statement plus a positive PHQ-2 and prior depression is a depression signal, and depression is independently associated with worse glycemic control and self-care. If you treat it as a motivational problem, you miss a treatable driver and reinforce her shame, which further erodes adherence.
Judgment point: the exam tests whether you hear a psychosocial cue inside a medical complaint and act on it, rather than pushing more education.
