IM11.19-20 | Diabetes Patient Skills and Counselling — Summary & Reflection

KEY TAKEAWAYS

Patient skills in diabetes encompass two core competencies. (1) Insulin injection technique (IM11.19): Subcutaneous injection targeting 3–4 mm SC depth; 4 mm pen needle at 90° (most adults); 8 mm requires skinfold or 45°; sites — abdomen fastest, thigh/buttock slowest; systematic rotation prevents lipohypertrophy; 10-second hold prevents dose leakage; prime pen before each injection; cloudy insulin roll ×10/invert ×10 before use; never mix glargine/detemir; store in-use at room temperature (≤30°C, 28–42 days depending on product). (2) SMBG technique (IM11.20): Wash hands first; use lateral fingertip; new lancet; gentle proximal pressure; log time and context; frequency depends on regimen (T1DM/MDI: 4–7 times/day; basal insulin only: fasting daily; oral agents: 2–3 days/week). SMBG patterns: elevated fasting → titrate basal insulin; elevated postprandial → adjust meal or prandial insulin; <70 mg/dL → apply 15–15 rule and review regimen; 3 am check to distinguish Somogyi (nocturnal hypo + rebound) from insufficient basal insulin.

REFLECT

Saraswathi, from the opening hook, came back with erratic glucose and a walnut-sized lipohypertrophy because no one had examined her injection sites or taught her rotation at the time of insulin initiation. Think about what you would do differently in the same situation: at the moment of prescribing insulin, you would now know to dedicate 10 minutes of the first visit to demonstrated technique training — show the injection step-by-step, have the patient do it back to you, give her a rotation grid, explain the 10-second hold, and schedule a follow-up in 2 weeks to review SMBG data and re-inspect the sites. This is the difference between a prescription that works and one that fails through no fault of the patient. The best pharmacological decision in the world is undone by a 2-second needle withdrawal. Patient skills education is clinical pharmacology applied.
