IM11.7-10 | Diabetes Clinical Evaluation — Summary & Reflection

KEY TAKEAWAYS

The diabetic clinical evaluation is structured around four NMC competencies: (1) History (IM11.7) — seven domains: presenting complaint, type differentiation (T1DM vs T2DM vs MODY vs secondary), risk factors, complications screen (eyes, kidneys, neuropathy, CVS), medications, lifestyle, and patient understanding. (2) Examination (IM11.8) — general inspection (BMI, waist circumference, acanthosis nigricans), BP (bilateral, supine/standing for orthostasis), cardiovascular, fundoscopy (grade retinopathy), peripheral pulses (all four limb pulses), and complete foot examination (monofilament, vibration, ankle jerks, inspection, Wagner grading). (3) Emergency recognition (IM11.9) — DKA: young T1DM, Kussmaul breathing, ketotic breath, dehydrated, abdominal pain; HHS: elderly T2DM, profound dehydration, no Kussmaul, neurological features, no ketotic breath; Hypoglycaemia: on insulin/SU, adrenergic symptoms then neuroglycopenia. (4) Differential diagnosis (IM11.10) — emergency first, then type classification by age/BMI/onset/ketonuria/family history, screen for secondary causes.

REFLECT

Mohan, from the opening hook, walked in with a single glucose result. After working through this module, think through what a structured 30-minute evaluation would have revealed: his family history might suggest MODY or familial T2DM; acanthosis nigricans on examination would confirm insulin resistance; absent ankle jerks would tell you he has had diabetes longer than he thinks; a hard exudate near the macula would send him urgently to ophthalmology today. A single number triggered a cascade of clinical reasoning. Reflect on this: the examination you perform today is the only window into the patient's prior decade of undetected hyperglycaemia. What would you feel if, at a follow-up visit in six months, you discovered he had already lost vision in one eye from proliferative retinopathy — retinopathy you would have found with a dilated fundoscopy on his first visit? The structured diabetic evaluation is not a checklist exercise — it is the mechanism by which you protect your patient's sight, kidneys, and limbs.
