36.93 Physician checklist/instructions for starting Insulin
Table of Contents
Summa Health System developed this checklist for physicians who are considering prescribing insulin to a patient. It is part of the Diabetes Planned Visit Notebook.
Physician Checklist for Starting Insulin as an Outpatient
Is the patient medically stable?
- No ketosis or electrolyte abnormality.
- No acute infection requiring hospitalization.
Is the patient psychologically stable?
- Assure proper home support.
Does the patient have arrangements for patient and family education?
- Visiting Nurse, or Summa Diabetes Center, or FPC nurse.
- NB: Summa Diabetes Center has an INDIGENT program.
Does patient have these educational materials?
- Blood Glucose and Urine Ketone Testing (tells when to test and when to notify physician).
- Your Insulin Regimen (written dosage and sliding scale).
- All about Insulin (tells how to handle insulin, dispose of needles)
- Treating Insulin Reactions and Hypoglycemia (tells how to recognize and treat hypoglycemia).
- Sick Day Plan and Sick Day Record (monitoring and notification during illness).
Did you calculate the patient's insulin requirements and prescribe an initial insulin regimen? (go to section below)
Does the patient have written prescriptions for:
- Glucose monitor, test strips and lancets.
Does the patient know to call daily and update physician or nurse regarding blood glucose levels and symptoms?
Insulin Treatment Regimens
Step One: Estimate Total Daily Dose (TDD) of insulin required
- Type I = approximately 0.5-1 Unit/kg/day.
- Newly diagnosed Type I 0.3 Unit/kg/day.
- Obesity may increase TDD to > 2 Units/kg/day.
Step Two: Identify basal and mealtime needs
BASAL insulin needs = approximately 50% of TDD
- most commonly use Novolin/Humulin N or L
MEALTIME insulin needs = approximately 50% of TDD
- most commonly use Novolin/Humulin R or
- Insulin Lispro (Humalog).
Step Three: choose an insulin regimen
a. Split Basal insulin into two doses
- Bedtime N or L (with or without) AM N or L, or
- Ultralente AC breakfast and supper.
b. Mealtime regimens based on choosing among 2,3, or 4 injection regimens
Step Four: adjust insulin regimen
- If fasting BG > 140, increase evening Basal dose (by approximately 10%).
- If BG < 150mg 1 to 2 hours post breakfast but > 120mg pre-lunch, increase breakfast Basal dose.
- If BG > 150mg 1-2 hours post breakfast, but < 120mg pre-lunch, increase breakfast R dose.
Blood glucose Goals: Pre meal < 120; 1-2 hours post meal < 150; Bedtime < 140
Practical One Injection Regimens for Type 2 DM
May add to oral agents
Administer at 9 PM
- HS NPH
3 to 4 AM peak may cause hypoglycemia, duration of action may cause pre-supper hyperglycemia.
- HS Ultralente
Peaks later, lasts longer.
- HS Glargine (Lantus)
No peak lasts 24 hours.
Begin any of these 3 regimens with
- 10 to 20 units or
- Calculate 0.1-0.2 Units/kg.
Adjust dose every 3 days based on Fasting Glucose
- If FBG > 140, Increase by 4 Units.
- If FBG 110-140, Increase by 2 Units.
- May consider D/C oral agent when FBG < 110.
Glargine (same dosing and adjustment as nighttime insulin)
- Less hypoglycemia than HS dosing.
May use 70/30 N/R mix, 50/50 N/R mix, 75/25 Glargine/Lispro mix
Same dosing and adjustment as Nighttime Insulin
Multi-dose Regimens to approximate physiologic insulin peaks
3 injection regimens (recommended)
a. N or Lente before breakfast and at bedtime Plus
R before breakfast and Supper
|Breakfast||25% TDD Novolin N (or Lente) plus 25% TDD Novolin R (or lispro)|
|Supper||25% TDD Novolin R (or lispro)|
|Bedtime||25% TDD Novolin N (or Lente)|
b. Ultralente before breakfast and supper Plus
R or Lispro before each meal
|Breakfast||30% TDD Ultralente plus 15% TDD Novolin R (or lispro)|
|Lunch||15% TDD Novolin R (or lispro)|
|Supper||TDD Ultralente plus 15% TDD Novolin R (or lispro)|
30% TDD Novolin N (or Lente) before breakfast and 25% TDD Novolin N (or Lente) at bedtime plus 15% TDD Novolin R (or Lispro) before each meal
|Breakfast||30% TDD Novolin N (or Lente) plus 15% TDD Novolin R (or Lispro)|
|Lunch||15% TDD Novolin R (or Lispro)|
|Supper||15% TDD Novolin R (or Lispro)|
|Bedtime||25% TDD Novolin N (or Lente)|
