Initiate scheduled insulin therapy for patients with confirmed admission blood glucose ≥180 mg/dL
STEP 1 — Gather Information
Collect admission blood glucose (BG) measurement and confirm it is ≥180 mg/dL on repeat testing; obtain history of diabetes (type, prior insulin use, diet/noninsulin medications, or no prior diabetes); assess nutritional status and severity of illness; check renal function and hypoglycemia risk factors.
STEP 2 — Rule In / Rule Out
Is the admission BG confirmed ≥180 mg/dL?
- No: Do not initiate scheduled insulin based on this criterion; consider other glycemic management approaches.
- Yes: Proceed to classification.
STEP 3 — Classify or Stratify
Classify by prior diabetes therapy:
- Insulin-treated prior to admission: Continue scheduled insulin regimen, adjusting basal and prandial doses for nutritional status and illness severity to maintain BG 100‑180 mg/dL.
- Diet or noninsulin medications prior to admission: Initiate either correctional insulin or scheduled insulin; if persistent hyperglycemia (≥2 POC‑BG ≥180 mg/dL in 24 h on correctional insulin alone), add scheduled insulin.
- No prior history of diabetes: Initiate correctional insulin or scheduled insulin; if persistent hyperglycemia (≥2 POC‑BG ≥180 mg/dL in 24 h), add scheduled insulin.
STEP 4 — Decide
Initiate scheduled insulin therapy (basal‑bolus or basal with correctional insulin) targeting glucose concentrations 100‑180 mg/dL; adjust doses based on ongoing BG monitoring, nutritional intake, and clinical status.
Clinical Guardrails / Mimics / Pitfalls
Avoid using sliding‑scale insulin alone for persistent hyperglycemia; monitor BG frequently to prevent hypoglycemia; do not delay initiation in patients with confirmed admission BG ≥180 mg/dL; be cautious in patients with renal impairment or high hypoglycemia risk; this recommendation does not override individualized plans for patients with known hypoglycemia unawareness.
Concrete Clinical Example
A 68‑year‑old woman with type 2 diabetes managed on metformin is admitted with admission BG 210 mg/dL confirmed on repeat. She has no prior insulin use. Start scheduled insulin (basal bolus) with basal insulin 0.15 U/kg and prandial insulin 0.05 U/kg per meal, plus correctional insulin for BG >180 mg/dL, aiming for BG 100‑180 mg/dL.
