Diabetes Guideline Overview and Treatments Flashcards
Two Guidelines
what are the two main diabetes guidelines?
Two Guidelines
- American Diabetes Association (ADA)-clinical practice Recommendations (updates annually (in january)
1.American Assocication of Clinical Endocrinologists (AACE)
updates periodically
What are the 2023 AACE guideline diabetes goals ?
A1C:
preprandial:
post prandial
2023 AACE guideliens
- A1C <6.5%
- pre prandial (FBG) < 110 mg/dL
- 2 hour post prandial: <140 mg/dL
If pt has any of these, less stringent a1c goal of 7-8% is recommended.
1.limited life expectancy
2. hx of severe hypoglycemia
3. hypoglycemia unawareness
- advanced renal disease
- pother severe comorbid conditions w. high risk for cvd event
- long t2d disease duration w. difficulty to attain an a1c goal
prohibitive cognitive and or psychological status
Complications-Centric Algorithm for Glycemic control
2023 AACE guidelines
Purpose
Pts. w. T2DM are at an increased risk of ASCVD and experience significant morbitdity and mortality (leading cause of mortality) despite contemporary therapy w. lipid modifying, antiplatelet, and antihypertensie agents.
need for a paradigm shift from an exclusively glucose-centric approach to a complications centric approach.
What are the ADA guideline diabetes goals ?
(NEW 2023 GUIDELINES GOALS)
A1C:
Pre prandial (FBG)
Post prandial:
NEW METRICS
TIR:
TBR:
Time <54 mg/dL:
(NEW 2023 GUIDELINES GOALS)
A1C: <7% (<8% for individuals with limited life expectancy or greater risk of hypoglycemia)
Pre prandial (FBG):80-130mg/dL
Post prandial: <180 mg/dL
New Metrics
TIR: >70%
TBR: <4%
Time <54 mg/dL: <1%
in this class. when to use each guideline?
if patient is <65 years old and without clinical ASCVD:STRICT TARGETS
use AACE guidelines
If patient is >/= 65 years old OR <65 with clinical ASCVD: LOOSE TARGETS
use ADA guidelines
according to AACE and ADA, what are the T1DM treatment
Treatment of T1DM
ADA and AACE recommendations
Multiple-dose insulin (MDI) 3-4 injections per day, or continuous subcutaneous insulin infusion (insulin pump)
educate patient on how to match prandial insulin based on carb intake, pre-meal blood glucose and anticipated
Pivotal TRials
DCCT:
UKPDS:
ACCORD TRIAL:
ADVANCE TRIAL:
VADT:
Pivotal Trials
(DCCT):
for type 1 diabetics. microvascular complications were reduced remarkably with intensive insulin treatment and A1C lowering and CV (macrovascular) benefit won’t be realized until years down the line
UKPDS
for type 2 diabetics. shows microvascular outcomes benefits are improved with intensive therapy.
ACCORD trial
focued individualize goals.intensive glycemic treatment strategyy was associated wuth a higher risk of death in older people with preexisting conditions.
ADVANCE. saw decreased ;microvssc with lower blood glucose, but did not see increase risk in mortality like accord
VADT Trial: saw decreased ;microvssc with lower blood glucose, but did not see increase risk in mortality like accord
