IBIDA (Inpatient Basal Insulin Dosing Assistant) — v1.4 (26Jan2026)

Offline tool for an initial once-daily insulin glargine PFS dose and next-day adjustment using weight, last 06:00 FBS, and renal function. Optional: HbA1c, previous Total Daily Insulin (TDD). Excludes shock/hypothermia.
Perioperative fasting here means: total fasting time (pre-op + post-op) expected to be > 12 hours. [Author & Copyright: © Prof J Kirtania, 2026]

1) Mandatory inputs

Actual body weight (kg) *

Last 06:00 AM FBS (mg/dL) *

Age (years) *

Sex *

Serum creatinine *

If µmol/L: app converts to mg/dL (divide by 88.4).

Height (cm) (optional; for BMI display only)

2) Optional inputs

HbA1c (%) (optional)

Previous Total Daily Insulin (TDD, units/day) (optional)

If provided (>0), app uses it only to estimate total glargine dose. No subtraction/balance is performed.

Perioperative fasting (pre-op + post-op total) expected > 12 hours

No shock & no hypothermia (required)

Show caveats

Clinical caveats (minimum):
• For DKA/HHS, shock, vasopressors, severe sepsis, hypothermia, pregnancy → follow critical care / IV insulin protocols.
• If type 1 diabetes or pancreatogenic diabetes: basal insulin is mandatory; avoid under-dosing; monitor closely.
• CKD (eGFR < 60) increases hypoglycemia risk → conservative dose and closer monitoring.
• Steroids, infection, enteral/TPN feeds can increase insulin requirement substantially.
• Hypoglycemia treatment in this order uses D25 100 mL IV stat;ensure local availability.
