A 12-Year-Old With Type 1 Diabetes, Two DKA Admissions, and Insulin Rationing
A 12-year-old boy with type 1 diabetes diagnosed at age 8 comes for quarterly follow-up. HbA1c is 9.4%, up from 7.9% a year ago, and he has had two diabetic ketoacidosis admissions in the past six months, both after running out of insulin. He uses insulin glargine at bedtime and aspart with meals. His mother works overnights as a cleaner and has three other children; the family recently lost SNAP eligibility after a paperwork error and has been using a food pantry. He eats school lunch and often skips the lunchtime dose "because the nurse is only there Monday and Wednesday and I don't want to bother the teacher." He checks his glucose about twice a week. When you ask about diabetes he says he feels fine and does not want to talk about it. Height velocity has dropped from the 50th percentile to the 25th percentile over the past two years.
1. What are the drivers of his rising A1c, and in what order do you prioritize them?
Read the worked answer
The A1c is a symptom, not the problem. Three drivers are visible and one is hidden.
Access: two DKA admissions after running out of insulin, plus a SNAP gap and food pantry use, point to a cost and supply failure, not refusal. Insulin rationing is a safety emergency, not an adherence problem.
School: dosing depends on a nurse who is present 2 days a week, so on 3 of 5 school days he has no plan. That is a system failure the family cannot fix alone.
Monitoring: checking glucose twice weekly means there is no data to act on and no way to learn from what he actually eats.
Hidden: his flat "I don't want to talk about it" and the falling height velocity need evaluation. Screen for depression (PHQ-9A) and diabetes distress, and check TSH and tissue transglutaminase, both of which affect growth and control.
Prioritize in this order: (1) uninterrupted insulin supply, (2) a school plan that guarantees dosing, (3) monitoring he can realistically do, (4) glycemic control. Leading with the A1c will make him disengage further, and the two DKA admissions are the only outcomes that can kill him this year.
2. What specific regimen and system changes do you propose at this visit?
Read the worked answer
Supply: ask specifically about the cost of each pen and whether he has ever stretched or skipped doses; screen for insulin underuse rather than asking about adherence. Route to social work the same day for SNAP reapplication, manufacturer patient assistance and monthly cost caps, 90-day fills, and 340B pharmacy pricing. Confirm he has a full stock before the next refill.
Regimen: with twice-weekly monitoring, discuss a continuous glucose monitor and verify coverage, because it collects data passively and reduces burden. Simplify to a basal dose plus a fixed mealtime plan rather than detailed carbohydrate counting until monitoring is reliable. Change one element at a time.
School: request a 504 plan and a written diabetes medical management plan naming trained designees who may administer insulin. Federal law obliges the school to provide this; the nurse's schedule is not a valid reason to withhold it.
Food: refer to a dietitian and to a produce prescription or food-as-medicine program, and write a letter supporting expedited SNAP review.
Measurement: agree on one goal he chooses, and set a realistic individualized A1c target (many adolescents target below 7%) that gets revisited rather than announced. A plan he did not help write is the plan that fails by spring.
3. What screening and advocacy steps follow from the growth change and the utilization pattern?
Read the worked answer
Screening due: PHQ-9A or PHQ-2 with follow-up, a diabetes distress measure, TSH, tissue transglutaminase IgA with total IgA, and a review of those results as the explanation for the growth deceleration before assuming puberty alone. Add a lipid panel and urine albumin-to-creatinine ratio according to age-based guidance.
Advocacy beyond the room: two DKA admissions in six months is a preventable-utilization signal. Ask whether the practice has a diabetes care coordinator or community health worker, whether the family has after-hours contact information that actually reaches someone, and whether hospital DKA discharges include a supply check before discharge. If they do not, that is a quality gap to raise with the medical director and a candidate for a plan-do-study-act cycle.
Communication: open with what is working - he is in school, he comes to visits, and he manages his own injections. Frame the plan as removing obstacles rather than improving compliance, and ask directly, "What would make diabetes easier this month?" Build the plan from his answer. For a 12-year-old with two recent DKA admissions and a parent working nights, the most useful intervention may be a nurse who calls weekly, not another education handout.
