glucose)

Risk Factors

• Testing should be considered in all adults who are overweight (BMI ≥25 kg/m2*) and have additional risk factors: • physical inactivity• first-degree relative with diabetes• high-risk race/ethnicity (e.g., African American, Latino, Native American, Asian American, Pacific Islander)• women who delivered a baby weighing >9 lb or were diagnosed with GDM• hypertension (≥140/90 mmHg or on therapy for hypertension)• HDL cholesterol level <35 mg/dl (0.90 mmol/l) and/or a triglyceride level >250 mg/dl (2.82 mmol/l)• women with polycystic ovarian syndrome (PCOS)• A1C ≥5.7%, IGT, or IFG on previous testing• other clinical conditions associated with insulin resistance (e.g., severe obesity, acanthosis nigricans)• history of CVD

______________________________________________________________________________________________

• In the absence of the above criteria, testing for diabetes should begin at age 45 years.______________________________________________________________________________________________

• If results are normal, testing should be repeated at least at 3-year intervals, with consideration of more frequent testing depending on initial results and risk status.

↵*At-risk BMI may be lower in some ethnic groups.

Normal Insulin Secretion

Fig. 49-1. Normal endogenous insulin secretion. In the first hour or two after meals, insulin concentrations riserapidly in blood and peak at about 1 hour. After meals, insulin concentrations promptly decline toward preprandial values as carbohydrate absorption from the gastrointestinal tract declines. After carbohydrate absorption from the gastrointestinal tract is complete and during the night, insulin concentrations are lowand fairly constant, with a slight increase at dawn.

Diagnostic Tests Used to Assess and Manage

Diabetes

A patient screened for diabetes at a clinic has a fasting plasma glucose of 120 mg/dL (6.7 mmol/L). The nurse explains to the patient that this value:

1. Is diagnostic for diabetes. 2. Is normal, and diabetes is not a problem.3. Reflects impaired glucose tolerance, which is an early stage of diabetes. 4. Indicates an intermediate stage between normal glucose use and diabetes.

management ability Assessment and management of

complications Client education

Nursing Role

Diabetes Control & Complications Trial (DCCT) Compared intensive treatment to standard treatment in 1,441 people with type 1 diabetes 60% reduction in risk between intensively treated group and standard group for retinopathy,

nephropathy, neuropathy (New England Journal of Medicine, 1993). Strict glucose control in type 1 diabetes reduces the risk of atherosclerosis (New England

Journal of Medicine, 2003).

Hyperglycemia is an independent marker of in-hospital mortality in patients with undiagnosed diabetes (Guillermo et. al.,2002).

Patients who are encouraged to become actively involved in managing their diabetes and feel they are competent to do so tend to be less depressed, more satisfied and have lower blood sugar levels (Williams et al., 2005).

NICE-SUGAR study

Evidenced-Based Practice

Plasma glucose (venous) Capillary blood glucose – some

meters have a 15% difference between capillary and venous blood. Capillary blood glucose is lower.

Continuous blood glucose monitoring – subcutaneous sensor

Testing new non-invasive methods,eg.wristband.

Blood Glucose Monitoring

Goals for Glycemic Control

A1C* < 7.0%** Only 43% achieve goal

Pre- Prandial glucose

90-130 mg/dl

Postprandial plasma glucose

< 180 mg/dl

*For non-pregnant individuals ** goal for patients in general; <6% for individual patients if feasible/safe

Management Principles for Older Adults with Complex

Illness/Frailty Overall treatment goals need to be individualized

Potential for hypoglycemic to occur from over aggressive treatment or from undesired adverse effects of medications or inadequate meal plans

In the case of frail older adults, where the risk of hypoglycemia exceed benefit from tight control, the HgbA1c value can be used as a means of monitoring treatment without a target goal

frail older adults with functional impairment and

limited life expectancy

Critically ill patients:- glucose results 140-180 mg/dl- tighter control for some populations (CABG)

Non-critically ill patients:- glucose results < 180 mg/dl

ADA Recommendations: Hospital Care

Identify in record as having DM and have order for blood glucose monitoring

Sliding scale insulin NOT recommended Hypoglycemia plan established and episodes

racked HbA1c drawn if none available form previous 2-3

months Education plan and follow-up developed New hyperglycemia - plans for follow-up testing

documented Assess: Pneumococcal and yearly influenza

Non-pharmacological Medical

Therapy for Type 2 Diabetes

Optimize BG Control Improve blood lipids Control blood pressure

Consistent carbohydrate intake

Monitor blood glucose to adjust therapy

Moderate weight loss –Bariatric surgery

Increase physical activity

Space meals

Modify fat and calorie content

Improve glucose and lipid levels Consistent day-to-day food intake. Weight management. Provide adequate nutrition across lifespan.

Nutritional Management: Goals

CHO 40-60% Protein 15-20% (reduced if client has renal

disease) Fat 30% or less

Less than 7% saturated fat No transfats

Vitamin & mineral requirements are the same as general population.

Macronutrient Recommendations

Carbohydrate counting Calorie control diet, e.g.

1800 kcal ADA diet Choose My Plate

Calories, Carbohydrates and Fat

Fruits, vegetables, fruit juice Breads, cereals, grains, pastries, starchy vegetables. Milk and yogurt If carbohydrate counting, 1 portion = 15 gm CHO Typical meal = 4-5 portions (60-75 gm) CHO

Carb counting activity Breakfast 45g CHO Lunch 60g CHO Dinner 60g CHO

Example: Carbohydrate Counting

Saturated (butter, hydrogenated fats) Polyunsaturated (vegetable oil) Monounsaturated- olive, canola Transfatty acids – in processed foods, e.g.

partially hydrogenated . . Omega 3 fatty acids – cold water fish,

walnuts

Focus on Type of Fat

Benefits Decreased blood glucose and improved insulin

sensitivity in type 2 diabetes Improved lipids Decreased blood pressure Oxygen consumption increased Improved blood flow Reduced cardiovascular risks Stress reduction Weight control

Exercise Management

Cardiovascular evaluation prior. Eye exam to r/o risk for retinal

detachment or vitreous hemorrhage with exercise.

Assess for safety concerns related to peripheral neuropathy.

Monitor CBG & B/P pre and post exercise. Consistency

Exercise Readiness Assessment:

Be knowledgeable regarding exercise plan. Monitor for safety hazards. Pre/post exercise assessment to monitor

tolerance of activity. If BG < 100 snack prior;100-150 snack after;

> 250 + ketones, no exercise.

Nursing Role: Exercise

Management of Hyperglycemia with

Pharmacologic Agents

Diabetic State

Where do hypoglycemic agents interact?

CHO Intake

Intestinal absorption

Decreased insulinsecretion

Increased hepaticglucose output Decreased peripheral

glucose uptake

Oral MedicationsClass Mechanism of Action

Sulfonylureasglipizide (Glucotrol), glyburide (Micronase, Diabeta) , glimepride (Amaryl)

Secretagogue: stimulates insulin secretion from beta cell

Meglitinidesrepaglinide (Prandin), nateglinide (Starlix)

Stimulate a rapid and short lived release of insulin from the pancreas

Biguanidemetformin (Glucophage), metformin ER (Glumetza)

Reduces hepatic glucose production; Sensitizer: increases insulin sensitivity to peripheral uptake, may cause lactic acidosis if kidneys are not functioning properly

Thiazolidineodionepioglitazone (Actos), rosiglitazone (Avandia)

Sensitizer: increases insulin sensitivity to peripheral uptake, causes edema, weight gain, not for heart failure pts.

a-glucosidase inhibitoracarbose (Precose), miglitol (Glyset)

Slows absorption of glucose, slows postprandial hyperglycemia

DPP-4 Inhibitorssitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta)

Enhances the incretin system, stimulates release of insulin from pancreatic B cells.

SGLT2 InhibitorsCanagliflozin (Invokana)dapagliflozin (Farxiga)

Sodium-glucose transporter 2 (SGLT2) works in the kidney to reabsorb glucose, and this new class of medication, SGLT2 inhibitors, blocks this action, causing excess glucose to be eliminated in the urine. Prone to UTI

Therapeutic Agents for Diabetes

Class Mechanism of Action

Bile Acid Sequestrant (BAS) colesevelam (Welchol)

A cholesterol-lowering medication that also reduces blood glucose levels in patients with diabetes

Dopamine Receptor AgonistBromocitine (Cycloset)

Increases CNS dopamine receptor activity, increases insulin sensitivity and decreases A1C by improving postprandial hepatic glucose metabolism and increasing glucose uptake

IncretinsExenatide (Byetta)Exenatide ER once-weekly (Bydureon)Liraglutide (Victoza)

Stimulates release of insulin, decrease glucagon secretion, increase satiety, decrease gastric emptyingInjectable

Amylin AnalogPramlintide (Symlin)

Decrease gastric emptying, decrease glucagon secretions and endogenous glucose output from the liver, increase satiety. For type 1 diabetes.

All patients with type 1 diabetes require insulin.

Many patients with type 2 diabetes will eventually need insulin.

As insulin deficiency progresses, a more physiologic multi-component insulin regimen will be required to adequately replace normal insulin secretion.

- Basal insulin - Meal-Related (prandial, bolus) insulin

Insulin Therapy in Diabetes

Insulins Onset Peak Duration Lispro* orAspart* ~15 minutes 60-90 minutes 2- 4 hours

Can you think like a pancreas ???

Basal / Bolus Concept

The use of two insulins with different characteristics to mimic the pancreas.

With the advent of long acting analogs insulin, we can mimic the pancreas by giving a slow release, virtually peakless, 24 hour basal insulin.

Rapid acting analogs are preferred over Regular for meal or prandial dose to cover carbohydrates consumed at meals.

The purpose of supplemental insulin (correction algorithm) is to bring a pre-meal elevated glucose level to target quickly and safely, used in addition to basal and bolus insulin.

Blood sugars stay in target due to the basal/bolus insulins.

Review of Basal/Bolus Concept

Basal insulins Lantus (insulin glargine) NPH

Bolus insulins Correction scale / supplemental insulin /sliding scale Humalog (lispro) Novolog (insulin aspart) Regular (best for tube feedings and hyperal)

• Monitor CBG at appropriate times based on insulin dosing, meals and activity

• Assess for hyper and hypoglycemia at appropriate times: Know when insulins are peaking

• Insulin Storage: Should be administered at room temperature. Can keep a vial of insulin at room temperature for 28-30

days. Avoid temperature extremes; maintain at 36-86 degrees

F. Unused,unopened vials should be stored in refrigerator

Impact of Comorbidities

Older adults, over age 65 and in particular, those of advanced old age, typically experience Multiple comorbidities Higher rates of physical disabilities functional

impairment Geriatric syndromes

DepressionCognitive impairmentFalls Urinary incontinence

*Used with permission from AACN GNEC Institute

Gerontologic Considerations

Prevalence increases with age. Presence of delayed psychomotor function

could interfere with treating hypoglycemia. Must consider patient’s own desire for

treatment and coexisting medical problems Recognize limitations in physical activity,

manual dexterity, and visual acuity Education based on individual’s needs, using

slower pace

80

Impact of Geriatric Syndromes

These syndromes are included in current screening recommendations for older adults with a diagnosis of Type 2 Diabetes

Further screening for these events within three to six months of a new diagnosis should accompany the initial evaluation period

82

Urinary Incontinence Older women with Type 2 Diabetes at increased

risk for urinary incontinence due to chronic hyperglycemia

Physiologically, excess glucose in the serum causes hyperosmolarity and shifts in fluid balance

Chronic hyperglycemia directly effects the genito-urinary system by causing symptoms of frequency, polyuria, nocturia and potentially urinary incontinence

Nursing Diagnoses

84

Self-Management Education Older adults with diabetes have special educational

needs secondary to sensory and other deficits related to the aging process

Educational plan: Include an assessment of the individual’s

priorities Use easily read or heard messages and proceed

at a slower pace utilizing significant others and caregivers in instruction

Elderly persons with diabetes need assistance with organization of information so they can slowly adapt it to their activities of daily living

*Used with permission from AACN GNEC Institute

Ideally, the goal of patient diabetes education is to:

1. Make all patients responsible for the management of their disease.

2. Involve the patient’s family and significant others in the care of the patient.

3. Enable the patient to become the most active participant in the management of the diabetes.

4. Provide the patient with as much information as soon as possible to prevent complications of diabetes.

Case Study 52-year-old woman was diagnosed with type 2 diabetes 6 years ago. Did not follow up with recommendations for care She works as a banking executive and gets little exercise. She has gained 18 pounds over the past year and eats a high-fat

diet. Complaining of weakness in her right foot

Began 1 month ago Difficult to dorsiflex and feels numb

Also complains of an itching rash in her groin area Has had rash on and off for many years Worse when weather is warm

Increased thirst and frequent nighttime urination Denies other weakness, numbness, changes in vision BP 162/98

Case Study

Random glucose test 253 mg/dL Hb A1C 9.1% Urine dipstick positive for glucose and

negative for protein Wet prep of smear from rash consistent with

Candida albicans ECG with evidence of early ventricular

hypertrophy by voltage

Discussion Questions

1. She wants to know why all of these changes have been happening to her body. How would you explain this to her?

2. What is the priority nursing intervention?3. What teaching should be done with her?
