# Es Basal Insulin Dose Reduction

> Consider reducing basal insulin dose by 10% to 20% at hospitalization for patients on basal heavy insulin regimens (≥0.6–1.0 units/kg/day) to prevent over‑coverage of meal‑related glucose excursions. Trigger phrases include “Patient on high basal insulin dose, should we reduce it during hospital stay?” and “Basal insulin dose ≥0.6 U/kg/day, consider reduction on admission.”

# Consider reducing basal insulin dose by 10% to 20% at hospitalization for patients on basal heavy insulin regimens

## STEP 1 — Gather Information
Collect patient weight, current basal insulin dose (units/day), calculate basal dose per kg, assess if basal heavy (≥0.6 U/kg/day), note recent inpatient glucose trends, nutritional status (NPO vs eating), and any planned changes in caloric intake or glucocorticoids. If basal dose ≥0.6 U/kg/day proceed to Step 2; otherwise maintain current basal dose.

## STEP 2 — Rule In / Rule Out
Determine if the patient is NPO or has significantly reduced carbohydrate intake compared to home. If yes (reduced intake), rule in for dose reduction; if no (normal or increased intake), rule out reduction and maintain basal dose.

## STEP 3 — Classify or Stratify
For patients ruled in, stratify reduction magnitude: 10% if mild reduction in intake or short stay, 20% if marked reduction (e.g., NPO, nil per os, or anticipated low oral intake) or expected prolonged hospitalization. Select the appropriate percentage reduction.

## STEP 4 — Decide
Calculate new basal dose = current basal dose × (1 – reduction fraction). Write order for reduced basal insulin at admission, monitor glucose q4‑6h and adjust as needed. Implement the reduced basal dose and set glucose monitoring plan.

## Clinical Guardrails / Mimics / Pitfalls
Do not reduce basal insulin in patients with persistent hyperglycemia (>180 mg/dL) or those on glucocorticoids that increase insulin needs; avoid reducing basal in patients with type 1 diabetes or those on glucocorticoids that increase insulin needs; avoid reducing basal in patients with type 1 diabetes or hypoglycemia unawareness; do not apply reduction if receiving enteral/parenteral nutrition with substantial carbohydrates; monitor for hypoglycemia and be prepared to increase dose if glucose falls <70 mg/dL.

## Concrete Clinical Example
78‑year‑old woman with T2D weighing 70 kg takes glargine 45 U daily (0.64 U/kg/day). Admitted for hip surgery, expected NPO for 24 h then clear liquids. Basal heavy → rule in. Marked intake reduction → 20% reduction. New dose = 45 U × 0.8 = 36 U glargine daily. Order written, glucose checked q6h; after first day glucose 110‑150 mg/dL, dose maintained.
