description: For adult patients with type 1 diabetes or insulin-treated type 2 diabetes hospitalized for noncritical illness who require prandial insulin, suggest either carbohydrate counting or fixed prandial insulin dosing. Triggered by clinician queries such as "Patient is T1D or insulin-treated T2D, how should we dose prandial insulin?"

# Suggest either carbohydrate counting or no carbohydrate counting with fixed prandial insulin dosing for type 1 or insulin-treated type 2 diabetes

## STEP 1 — Gather Information
Collect diabetes type (T1D or insulin-treated T2D), confirmation of noncritical illness hospitalization, need for prandial insulin therapy, patient's carbohydrate counting proficiency and preference, availability of diabetes expertise/resources for CC, current basal insulin dose, and recent glucose trends. Proceed to determine eligibility for CC vs fixed dosing.

## STEP 2 — Rule In / Rule Out
Is the patient diagnosed with type 1 diabetes or insulin-treated type 2 diabetes and hospitalized for noncritical illness? If yes, proceed to Step 3; if no, consider noninsulin-treated T2D pathway (suggest not using carbohydrate counting per Recommendation 9.1) and exit this skill.

## STEP 3 — Classify or Stratify
Assess patient's carbohydrate counting ability, preference, and institutional resources (expertise, policies, training). If patient is proficient, prefers CC, and expertise/resources are available, classify as suitable for carbohydrate counting; otherwise classify as suitable for fixed prandial insulin dosing.

## STEP 4 — Decide
If classified for carbohydrate counting, implement CC using an individualized insulin-to-carbohydrate ratio (ICR) with adjustments for illness-related insulin resistance; if classified for fixed dosing, administer fixed prandial insulin doses (e.g., weight-based 0.2–0.4 units/kg per meal) plus correctional insulin for premeal hyperglycemia > target.

## Clinical Guardrails / Mimics / Pitfalls
CC requires a hospital policy, expertise from a diabetes professional, and adjustments to ICR may be needed due to illness, glucocorticoids, infection, or surgery; avoid CC if resources lacking. Fixed dosing should be weight-based and include correctional insulin; reduce basal insulin by 10–20% in basal-heavy regimens (≥0.6 units/kg/day) to prevent hypoglycemia. Do not use CC without expertise or policy guidance.

## Concrete Clinical Example
A 62-year-old woman with T1D admitted for cellulitis reports using CC at home, has access to a diabetes educator, and prefers to continue; her ICR is 1 unit per 10 g CHO, adjusted downward 20% during hospitalization. A 70-year-old man with insulin-treated T2D admitted for COPD exacerbation has difficulty with carb counting; fixed prandial insulin of 4 units per meal plus correctional insulin based on premeal glucose is used.
