E. et al. Diabetes Care 2013;36:3430-3435 23 CHALLENGES TO ORAL DIABETES THERAPIES IN THE HOSPITAL Many restrictions to use of orals in the hospital: Renal or hepatic impairment (e.g. metformin, sulfonylureas, TZD, SGLT-2) Volume overload (TZD) Changing nutritional status or malnutrition (insulin secretagogues) Contrast dye for imaging or procedures (metformin) Slow pharmacokinetic profiles of oral agents infective for rapid changes in glucose and insulin requirements Risk of hypoglycemia is unclear in the hospital setting 24 8
CURRENT GUIDELINES FOR GLUCOSE TARGETS Non ICU Patients: Premeal glucose targets <140 mg/dl Random blood glucose (BG) <180 mg/dl To avoid hypoglycemia, reassess insulin regimen if BG levels fall below 100 mg/dl Some patients may be maintained with a glucose range below and/or above these cut-points Hypoglycemia = BG <70 mg/dl Severe hypoglycemia = BG <40 mg/dl Umpierrez et al, Management of Hyperglycemia in Hospitalized Patients in Non-Critical Care Settings: An Endocrine Society Clinical Practice Guideline.

Continue metformin and pioglitazone but increase glyburide dose 2. Discontinue all oral agents and start Sliding Scale insulin therapy Q 4-6 hours 3. Start a basal (intermediate or long acting) + bolus (rapid acting ) insulin regimen 27 9
KEY CONCEPTS OF EFFECTIVE INSULIN THERAPY Basal insulin Controls hepatic glucose production Food(prandial prandial) insulin Based on meal carbohydrate content Correction(supplemental supplemental) insulin Treats acute elevation in blood glucose 28 INITIATING A BASAL BOLUS INSULIN REGIMEN No clue where to start??? 29 WEIGHT BASED INSULIN DOSING INITIAL DOSING FOR BASAL + BOLUS INSULIN REGIMEN Actual Body Weight (kg): 50 60 70 80 90 A: Basal (Lantus (insulin glargine) once daily) Insulin Sensitive (BMI less than 20, ESRD) 5 6 7 8 9 Insulin Average (BMI 20-30, less than 2 agents, admit blood glucose (BG) less than 200mg/dL) 10 12 14 16 18 Insulin Resistant (BMI more than30, on more than 2 agents, admit BG more than 200, on steroid therapy 15 18 21 24 27 Adjust: if fasting BG greater than 140mg/dL and none less than 70mg/dL +2 +2 +3 +4 +5 Adjust: if fasting BG less than 70mg/dL -2-3 -4-5 -5 B: Mealtime TID--Humalog (insulin lispro) (Caution if poor appetite; may use different dose each meal) Insulin Sensitive 2 2 3 3 3 Insulin Average 3 4 5 5 6 Insulin resistant 5 6 7 8 9 Adjust: if fasting BG greater than 140mg/dL and none less than 70mg/dL +1 +1 +2 +2 +3 Adjust: if premeal BG less than 70mg/dL -2-2 -2-3 -3 C: Corrective Humalog (Insulin lispro): Start algorithm #2 (unless ESRD, then start #1) Total Daily Dose (TDD) calculations above are based on: Choose patients level of insulin resistance Insulin sensitive 0.2 units/kg/day Insulin Average 0.4 units/kg/day (sensitive/average/resistant) and match to Insulin Resistant 0.6 units/kg/day patient s weight in kg to find the dose of Lantus and Lispro with meals. 30 10
WEIGHT BASED INSULIN DOSING Basal Insulin Dosing Prandial Insulin Dosing EHR will auto calculate the basal and prandial insulin dosing with weight based dosing option 31 CORRECTION INSULIN 32 ADMISSION #1 READY FOR DISCHARGE Patient has been treated with basal bolus insulin regimen Glucose has been between 100-180 mg/dl Uncomplicated postop recovery Cr is 1.8 What should the discharge regimen be? Reassess pre-admission regimen: Outpatient DM Meds: metformin 1000mg bid, glyburide 5mg bid, sitagliptin 100mg daily Labs: Admission glucose 220 mg/dl HgbA1c 9.2%, creatinine 1.6, 33 11
CONSIDERATIONS WITH NON- INSULIN DIABETES MEDICATIONS Renal Insufficiency: Metformin: Cr > 1.5 (egfr < 60 cc/min) in men and > 1.4 in women for metformin Sulfonylureas (exception of glipizide) Reduce doses for some DPP4 Inhibitors, GLP1-RA agonists and SGLT-2 inhibitors Hepatic Insufficiency: Metformin and TZD: LFT s >2-3x upper normal Volume Overload: TZDs: Renal failure, liver failure, heart failure 34 DISCHARGE REGIMENS A1c Preadmission Regimen <7% Continue previous regimen 7-8% Increase doses of previous agents or add additional oral on non-insulin agent. If already on max dose of 2 oral agents, consider basal insulin 8-9% Add basal insulin to previous oral or non-insulin regimen or if already on basal insulin, change to multiple daily injections >9% Multiple daily injections What is the A1c? Other Considerations for Patient Centered Approach: Financial Patient cognition, literacy, ability to comply Risks of hypoglycemia Weight management Follow up as outpatient 35 ADMISSION #2: SOB 56 year old male admitted to the floor with pneumonia and COPD exacerbation History of T2DM for 6 years DM Meds: Metformin 1000mg BID, canagliflozin 300mg daily Labs: Glucose 190 mg/dl, Cr= 1.0, HgbA1c = 6.7% Started on antibiotics and solumedrol 60mg iv daily How should we treat his diabetes? 1. Continue metformin and canagliflozin 2. Discontinue orals and start sliding scale insulin therapy every 4-6 hours 3. Start basal + bolus insulin therapy 36 12
INSULIN REGIMENS FOR CORTICOSTEROIDS Insulin Requirement High a.m. dose corticosteroids 8 12 6 10 Consider NPH with rapid acting regimens Dose basal insulin higher during the day than overnight Dose prandial insulin higher towards the end of the day May need a ratio of higher prandial than basal insulin (60-70% prandial vs. 30-40% basal) 37 SUGGESTED INSULIN DOSING FOR STEROID TAPER Prednisone Dosage (mg/day) 40 0.4 30 0.3 20 0.2 10 0.1 Insulin Dosage (U/kg) Consider other comorbid conditions that would increase or decrease insulin resistance and adjust the ratio Clore J, Thurby-Hay L.

Labs: Glucose= 225 mg/dl, repeat was 253 mg/dl HgbA1c = 5.9% Creatinine = 1.8 AST/ALT = normal Managed with pressors, corticosteroids, antibiotics and vent support Excellent glycemic control was achieved with intravenous insulin infusion 39 13
ADMISSION #3 CONTINUED Over the next few days, the patient improves significantly. Pressors are weaned off and steroids are reduced. She is extubated. Tube feedings were started and titrated to goal rate 24 insulin requirements from insulin infusion while on stable TF rates are 65 units Renal and liver function returning to normal Ready for transfer to floor on current TF regimen with plans for swallow study in a few days. What should we do with the insulin regimen? 1. D/C insulin infusion and start sliding scale insulin only 2. Transition to a basal + SC insulin regimen with sliding scale 3. Start metformin 500mg bid and Glyburide 5mg daily 40 SUBCUTANEOUS INSULIN REGIMENS FOR NPO, PARENTERAL OR ENTERAL NUTRITION Options for Insulin Regimen: 1.

Hydrocortisone is tapered off The TF are discontinued at 10 am Last NPH dose was at 8 am as scheduled At 1 pm, she has a hypoglycemia to 45 mg/dl What happened? 42 14
HYPOGLYCEMIA WITH SUDDEN INTERRUPTION IN CALORIES D10% IVF readily available for patients and start at the same rate as the nutritional rate if on TPN or tube feeds Continue D10% until tube feeds resumed or effect of long acting insulin is worn off ADJUST THE INSULIN THERAPY OR NOTIFY THE PRIMARY PROVIDER 43 SPECIAL REGIMENS FOR CONTINUOUS TPN OR TUBE FEEDS For patients on continuous tube feeds or TPN, recommend a regimen of NPH Q 8 hours with lispro Q 4 hours Special nursing instructions: Start Dextrose 10% IV during any interruption in tube feeds or TPN up to a max of 40 cc/hr. HOLD next insulin dose and notify prescriber for further orders. 44 ADMISSION # 3 DISCHARGE REGIMEN Blood sugars have been normal without additional insulin on stable oral diet Ready for discharge Does the patient need insulin or oral agents for discharge? Reminder: Admission HgbA1c = 5.9% 45 15
HOSPITAL HYPERGLYCEMIA REQURIES DISCHARGE FOLLOW UP In those with previously diagnosed diabetes, newly diagnosed diabetes, or elevated A1c Initiate therapy or revise preadmission regimen as required In those without previously diagnosed diabetes Differentiation between hospital-related hyperglycemia and undiagnosed diabetes requires follow-up testing (FBG, 2h OGTT, A1c) once metabolically stable using established criteria 46 DISCHARGE TRANSITION Diabetes Education Survival Skills Nutrition counseling for carbohydrate and calorie restriction Reassessment of admission treatment regimen Transition to non insulin therapy, if appropriate Outpatient follow-up and referrals for on going care Clear, written medication instructions for patients 47 ADMISSION #4: HOSPITAL ACQUIRED CONDITION 32 year old male admitted for Left femoral-popliteal bypass H/o Type 1 DM for >20 years on an insulin pump at home and on admission. HgbA1c was 6.7% on this regimen On admission he was placed NPO after midnight and insulin pump was removed and sliding scale was ordered On the morning of surgery, patient was found to be confused, tachypneic with shallow respirations Labs: Glucose =426, Potassium = 5.6, ph =7.2 Bicarb=14, anion gap of 16, positive serum ketones What happened??? 48 16
DANGERS OF SLIDING-SCALE INSULIN REGIMENS Sliding Scale Insulin is a reactive therapy provides supplemental insulin after hyperglycemia occurs No basal (long term) insulin coverage which is critical for patients with Type 1 diabetes Iatrogenic DKA! 49 DIABETES TECHNOLOGY IN THE HOSPITAL Increasing utilization of outpatient technology will follow patients into the hospital Continuous Subcutaneous Insulin Infusion (CSII) or Insulin Pump therapy Continuous Glucose Monitoring (CGM) Advantages: less severe glycemic excursions, programmed to avoid hypoglycemia, patient satisfaction Disadvantages: not well studied or approved in the hospital, unfamiliarity with non-endocrine trained staff, not proven to be more efficacious in inpatient settings 50 TYPES OF TECHNOLOGY 51 17
CSII - BASICS Pump Feature Basal Rates Ex: 00:00 0.95 U/h, 06:00 0.5 U/h, 17:00 0.6 U/h Bolus Insulin to carbohydrate ratio (ICR) or Carb Ratio (CR) Ex: 00:00 10 grams, 08:00 12 grams Insulin Sensitivity Factor (ISF) or Correction Factor (CF) Ex: 00:00 50 mg/dl, 12:00 35 mg/dl Description Rateof continuous infusion of a rapid acting insulin (lispro, aspart, glulisine, or Regular U500) Set by time of day Multiple rates throughout the day Can be set to hundredths of a unit per hour Amountof carbs for a unit of insulin Individualized for each patient Accurate dosing of insulin for the carbs Amountof decrease in glucose per unit of insulin Individualized for each patient Target Glucose Ex: 00:00 90-120 mg/dl; 12:00 100-130 mg/dl Insulin on Board (IOB) or Active Insulin Time (AIT) Ex: 4 hours Glucose level above which a correction dose is given Duration of time betweensuccessive correction doses, avoids stacking 52 CONTINUOUS SUBCUTANEOUS INSULIN PUMPS (CSII) Some small, single center studies have shown that continuing CSII is safe in the hospital Standardized hospital protocols, order sets and patient consents are strongly recommended Key is to identify that the patient is using their own supplied insulin pump and has mental capacity to continue the therapy Protocol should include safety parameters that address the frequency of glucose monitoring, daily pump site and patient assessment, and hypoglycemia treatment Noschese et al. Endo Prac 2009; 15(5): 415-424 Nassar et al. J Diabetes Sci Techbol. 2010;4(4):863-72 53 PERIOPERATIVE MANAGEMENT OF CSII Retrospective review of patients with CSII preoperatively for elective surgeries 49 patients undergoing 57 surgeries Protocol in place for CSII management Efficacy: 63% had postop CBG of 200 mg/dl, Safety: No intraoperative or postoperative hypoglycemia <70 mg/dl Lower mean postoperative glucose if surgery was less than 120 minutes, more patients met this endpoint CSSI is safe and efficacious, especially for surgery <120 min Sabel et al. Endo Prac 2015, 21(111):1269-1276 54 18
CSII SURGERIES AND PROCEDURES Plan ahead before elective surgeries Can continue CSII during short procedures at discretion of surgeon and anesthesiologist if pump site does not interfere with surgical field May use short acting SQ insulin if CSII is held for 1-2 hours. If CSII is to be held for > 3 hours, start basal bolus insulin regimen Can reduce basal rates with the temp basal function by a 20-50% of the usual rate AACE Consensus Panel on Insulin Pump Management Endo Prac 2010 16(5): 746-762 55 CONTINUOUS GLUCOSE MONITORING (CGM) Currently not FDA approved in the hospital setting Most studies are in ICU patients or postoperative patients Accuracy is a concern due to interference with medications (e.g. Tylenol) and physiological changes during acute illness (ph, volume overload, etc.) No guidelines or protocols available to incorporate this data into management More research is needed in the inpatient setting 56 CHALLENGES TO GLYCEMIC CONTROL IN THE HOSPITAL SETTING 19
BARRIERS IN THE HOSPITAL Diabetes/hyperglycemia often overlooked on admission and throughout the hospitalization if it is not the primary diagnosis Hypoglycemia feared and often over-treated Lack of familiarity with the increasing types of diabetes therapies currently available Traditional sliding scale protocols continue to prevail due to ease and lack of education 58 BARRIERS IN THE HOSPITAL Increased workload on nursing Timing of insulin with the glucose check and meals may still be problematic Lack of coordination between departments, e.g., nutrition, radiology, nursing, etc. Frequently changing nutritional status, medications and organ function that affects glycemic control Complexity of individualized dosing + need to make daily adjustments 59 CONDITIONS PREDISPOSING PATIENTS TO HYPOGLYCEMIA Advanced age Sepsis/shock Malnutrition Burns Gastrointestinal malabsorption Cerebrovascular accident Hypoglycemia unawareness Altered Mental Status Goldberg PA et al. Diabetes Spectrum. 2005;18:28-33. Congestive heart failure Renal insufficiency Adrenal/pituitary insufficiency Liver disease Pregnancy Alcoholism Polypharmacy (drug interactions) 60 20
