Parameters

Inpatient Basal-Bolus & Correction Insulin Sliding Scale Calculator Result

Formula

TDD (units/day) = Weight (kg) × Factor (0.3 to 0.8)
Basal = 50% TDD | Prandial = 50% TDD divided by 3 meals
ISF (Rule of 1800) = 1800 / TDD | Correction = (BG - Target BG) / ISF

Clinical Pearls

Replaces dangerous isolated sliding-scale monotherapy with physiological basal-bolus-correction regimen, dramatically reducing inpatient glycemic variability and surgical site infections.

Limitations

Correction scale must be adjusted downward in severe acute renal failure or acute liver injury due to prolonged insulin half-life.
