| description | In adults with diabetes treated with diet or noninsulin medications before admission, suggest initial therapy with correctional insulin or scheduled insulin to maintain glucose targets of 100–180 mg/dL. Trigger phrase: "Patient on diet or noninsulin meds before admission, start with correctional or scheduled insulin?" |
Initiate correctional insulin or scheduled insulin therapy for patients with diabetes treated with diet or noninsulin medications prior to admission
STEP 1 — Gather Information
- Confirm diabetes treated with diet or noninsulin medications prior to admission (no insulin use).
- Obtain admission point-of-care blood glucose (POC-BG).
- Assess for persistent hyperglycemia (≥2 POC-BG ≥180 mg/dL in 24h) after starting therapy.
STEP 2 — Rule In / Rule Out
Is the patient on diet or noninsulin diabetes medications before admission?
- Yes → Proceed to Step 3.
- No (patient was on insulin prior) → Follow different pathway (not covered here).
STEP 3 — Classify or Stratify
- If admission POC-BG ≥180 mg/dL → Consider initiating scheduled insulin (basal or basal-bolus) plus correctional insulin.
- If admission POC-BG <180 mg/dL → Start with correctional insulin alone, then monitor for persistent hyperglycemia.
STEP 4 — Decide
- For admission POC-BG ≥180 mg/dL: Initiate scheduled insulin (e.g., basal insulin) plus correctional insulin before meals.
- For admission POC-BG <180 mg/dL: Start correctional insulin alone; if persistent hyperglycemia develops (≥2 POC-BG ≥180 mg/dL in 24h), add scheduled insulin therapy.
Clinical Guardrails / Mimics / Pitfalls
- Do not rely solely on sliding scale insulin for persistent hyperglycemia; escalate to scheduled insulin.
- Avoid delaying insulin initiation when admission BG ≥180 mg/dL.
- Do not use noninsulin therapies as first-line in this population per guideline (they are less effective).
- Monitor for hypoglycemia, especially when adding scheduled insulin.
Concrete Clinical Example
A 65-year-old with type 2 diabetes on metformin prior to admission has admission POC-BG 158 mg/dL. Start correctional insulin (rapid-acting) before meals and at bedtime. After 24 hours, two POC-BG readings are 195 mg/dL and 202 mg/dL (≥180 mg/dL). Add basal insulin (e.g., glargine 10 units nightly) while continuing correctional insulin.
