This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Glycemic Management Across the Lifespan for People With Type 1 Diabetes: A Clinical Practice Guideline. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Use physiologic insulin replacement with structured glucose monitoring and individualized education; never stop basal insulin during illness.
  • Teach hypoglycemia prevention and sick-day ketone management, with urgent assessment for suspected diabetic ketoacidosis.
  • Screen systematically for microvascular, cardiovascular, autoimmune and psychosocial complications using the current Canadian guideline.
  • Ensure access to glucose and ketone monitoring, insulin supplies, glucagon and structured education.

Practical assessment and management workflow

1
Confirm diabetes type and assess insulin regimen, technology, hypoglycemia, nutrition and injection sites.
2
Set individualized glucose and A1C goals and align basal, mealtime and correction insulin with daily life.
3
Review sick-day rules, exercise, driving, alcohol and pregnancy planning at appropriate visits.
4
Screen eyes, kidneys, feet, thyroid, celiac disease and cardiovascular risk on the Canadian schedule.

Safety, red flags and urgent escalation

  • Never stop basal insulin during illness; check ketones and escalate vomiting or acidosis symptoms.
  • Treat severe hypoglycemia immediately and review cause, awareness and driving safety afterward.
  • Have a perioperative and hospital insulin plan to prevent omission and ketoacidosis.
