in patient treatment of diabetes mellitus Flashcards
Blood Glucose Classifications
Hospital hyperglycemia:
hypoglycemia:
Severe hypoglycemia
Stress hyperglycemia:
Blood Glucose Classifications
Hospital hyperglycemia: BG>140
hypoglycemia: <70 mg/dL
Severe hypoglycemia <40 mg/dL
Stress hypoglycemia: elevation in BG in a patient with no history of dm (AND AN A1C <5.5%
ASSESSMENT on Admission
ASSESSMENT on Admission
- determine patient history. either type 1 or type 2
- obtain laboratory blood glucose testing
- recommend to obtain A1c for all pts with a hx of DM or BG>140
a. if no A1C from the past 3 mo.
b. if no hx of DM but BG>140 mg/dL
c. A1C >/= 6.5% indicates DM - If pt. has hx of DM or A1C comes back >/= 6.5%-> regular POC blood glucose monitoring
Point of Care Blood Glucose Mintoring
Point of Care Blood Glucose Mintoring
Point of Care (POC) BG monitoring: mentoring glucose at beside. preffered method for testing BG in the hospital setting
if eating: recommend before meals and at betime
if NPO or not reacieving ocntinuous enteral feeds, recommended q4-6hr

BG Targets
Non Critical Patients
Pre meal: BG <140 mg/dL
Random BG: <180 mg/dL
when to modify: <100 mg/dL
Overview of pharmacologic therapy
Overview
- hold all oral antidiabetics (holding metformin is controversial. put in flash cards why)
- SQ insulin recommended for most patients (Work horse)
- continous insulin infusion recommended for some patients
Insulin regimen: The preffered approach
Insulin: The preffered approach
- Basal Insulin; manages fasting BG (ex. glargine)
- nutritional regimen : prevents the rise in glucose after eating meals (short or rapid)
- correctional: extra insulin beyond the schedules regimensto help correct bG that is still above target
Dosing of Insulin
I.Type 1
II.Type 2
Dosing of Insulin
I. Type 1
1. obtain patient weight in kg
- calculate total daily dose: 0.2-0.4 units/kg/day
- choose dosing schedule:
a. 50-60% basal
b. 40-50% as nutritional insulin
c. use correctional insulin for BG values above goal
adjust based on BG values, change in clinical status, or made NPO
II.Type 2
- D/C all oral and non insulin injectable antidiabetics on admission
- calculate total daily dose:
insulin naive patient: 0.3-0.5 units/kg/day. use lower doses in elderly and in renal impaired.
if patient has Outpatient use of insulin: reduce outpatient dose by 20-25% due to dietary changes while in patient
- choose dosing schedule:
a. 50% basal
b. 50% as nutritional insulin
c. use correctional insulin for BG values above goal
Drug induced alterations of blood glucose
increase HYPER:
Drug induced alterations of blood glucose
increase HYPER: corticosteroids atypical antipsychotics fluroquinolon ABX calcineurin inhibitors protease inhibitors thiazide diuretics
Drug induced alterations of blood glucose
increase HYPO:
Drug induced alterations of blood glucose
increase HYPO: beta blockers fluoroquinolone ABX alcohol pentamidine
Risk reductio strategies:
Risk reductio strategies:
calla with hospital dietitians to adjust nutrition components for a diabetic patient
coordinate BG testing ih insulin administration and meal delivery
use good communication skills during patient transfer between floor, shifts
double check orders for completion and accuracy before prescribing prescribers and verifying (pharmacy)
performing best practices to avoid medications errors with insulin
stocking ily one concentration of insulin infusion bags
sadradize insulin protocol for various situations
adjust insulin regimen appropriately based on glucose reading.
fasting and primal glucose >140, increase dose of glargine by 20%
For hypoglycemia
protocols to manage hypoglycemia
anticipate scenarios that may require a decrease in insulin dosing (Enteral feeds r TPN D/C, reduction of food intake or change to NPO status, reduction/ D/C of meds that can increase BG (including IV dextrose)
