STEP 1 — Gather Information
Collect patient diabetes type (type 1 vs type 2), insulin treatment status (insulin-treated vs noninsulin-treated), and requirement for prandial insulin therapy.
STEP 2 — Rule In / Rule Out
Determine if the patient is noninsulin-treated type 2 diabetes requiring prandial insulin. If yes, rule out carbohydrate counting; proceed to fixed dosing. If no (i.e., type 1 diabetes or insulin-treated type 2 diabetes), proceed to consider carbohydrate counting.
STEP 3 — Classify or Stratify
For patients where carbohydrate counting is an option, assess hospital readiness: presence of a carbohydrate counting policy and availability of a healthcare professional expert in diabetes management. If both are present, classify as eligible for carbohydrate counting; otherwise, classify as requiring fixed prandial insulin dosing.
STEP 4 — Decide
If eligible for carbohydrate counting, implement carbohydrate counting using an individualized insulin-to-carbohydrate ratio; if not eligible, use fixed prandial insulin dosing based on weight or standard meal plan.
Clinical Guardrails / Mimics / Pitfalls
Do not apply carbohydrate counting in noninsulin-treated type 2 diabetes patients requiring prandial insulin; avoid carbohydrate counting when hospital lacks policy or trained expertise; adjust insulin-to-carbohydrate ratios for illness-related insulin resistance; never use carbohydrate counting without verifying meal carbohydrate content and timing.
Concrete Clinical Example
A 62-year-old woman with type 1 diabetes admitted for cellulitis requires prandial insulin. The hospital has a carbohydrate counting policy and a diabetes care and education specialist. She uses an insulin-to-carbohydrate ratio of 1 unit per 15 grams of carbohydrate. For a lunch containing 60 grams of carbohydrate, she receives 4 units of prandial insulin.
