Management of Hyperglycemia and Diabetes in the Hospital: Case Studies Bruce W. Bode, MD, FACE Atlanta Diabetes Associates Atlanta, Georgia Hyperglycemia in Hospitalized Patients • Hyperglycemia occurred in 38% of hospitalized patients — 26% had known history of diabetes — 12% had no history of diabetes • Newly discovered hyperglycemia was associated with: — Longer hospital stays — Higher admission rates to intensive care units — Less chance to be discharged to home (required more transitional or nursing home care) Umpierrez GE, et al.

If the current BG Tier has dropped, stay in the same column to determine the new drip rate (ml/hr). 2. If the current BG Tier has not changed or is higher, move 1 column to the right to determine the new drip rate (ml/hr). c) When hourly BG is 80-110, remain in the current column and adjust the rate according. d) When hourly BG is less than 80, move 1 column to the left to calculate new drip rate and refer to Figure 2. 6) Treatment for hypoglycemia (BG less than 80) a) Move 1 column to the left and give D50 by IV push using dosing chart provided (see Figure No. 2) b) Recheck BG in 15 minutes (repeat 6a above if BG is still less than 80) c) Resume hourly BG monitoring and insulin drip adjustments 7) Notify physician If: a) BG is less than 60 for 2 consecutive BG measurements. b) BG reverts back to levels greater than 200 for 2 consecutive BG measurements. c) Insulin requirement exceeding 24 units per hour does not result in a lower BG level. d) Patient’s K+ level drops to less than 4. e) Continuous enteral feedings, TPN, or IV insulin infusion is stopped or interrupted. 8) Transition to subcutaneous insulin a) BGs should be within target range for at least 4 hours before IV insulin is discontinued b) Calculate total daily insulin (TDI) = (units of insulin for the last 4 hours of IV drip) x (6) for patients on D5W c) Begin glargine = 50% TDI (for pregnant patients use NPH twice daily) d) Begin fast acting analog = 50% TDI divided by 3 (give 3 times a day immediately before meals). e) Continue IV insulin infusion for 2 hours after initiation of subcutaneous therapy. f) Refer to Subcutaneous Insulin Standing Orders for administration times and dosage adjustments. g) Refer patient for diabetes education, nutritional services, and discharge planning (to ensure the patient can afford medications/supplies and has follow-up disease state management after discharge).

Juice with sugar added 2. 50% IV dextrose (1 amp or 50cc) 3. 50% IV dextrose (1/2 amp or 25cc) 4. 50% IV dextrose (based on glucose level) Protocol for Insulin in Hospitalized Patient Treatment of hypoglycemia • Any BG <80 mg/dL: D50 IV = (100 - BG) x 0.4 • If eating, may use 15 gm of rapid CHO (prefer glucose tablets) • Do not hold insulin when BG normal Hospital Diabetes Plan What can we do for patients admitted to the hospital? • Protocols for all diabetes/hyperglycemic patients • Finger stick BG AC QID on all admissions • Check all steroid-treated patients • Diagnose diabetes — FBG >126 mg/dL — Any BG >200 mg/dL Hospital Diabetes Plan (cont’d) What can we do for patients admitted to the hospital? • Document diagnosis in chart — Hyperglycemia is diabetes until proven — Bring to all physicians’ attention — Note on problem list and face sheet • Check hemoglobin A1C • Hold metformin; Hold TZD with CHF, liver dysfunction • Start insulin in all hospitalized patients with BG >140 mg/dL Defining and Identifying Hyperglycemic Patients Goal: Studies have proven that the outcomes of hospitalized patients are greatly enhanced when steps are taken to improve the patient’s glycemic state. Therefore, all patients presenting with hyperglycemia will be identified using the patient’s initial “basic metabolic profile.” Patient Presents with Hyperglycemia Previously diagnosed DM Diabetic Ketoacidosis Hyperglycemic Crisis Follow DKA Protocol No Previous Diagnosis DM And BG > 140 Begin BG testing Modification of therapy And referral for dietary And educational consult BG is >140 for a critically ill patient, notify physician for consideration to initiate therapy BG is > 180 for a non- , critically ill patient, notify physician for initiation of Subcutaneous therapy When adult blood glucose levels > 140 still occur after initiation/modification of therapy, consideration should be given to begin IV insulin infusion (see patient and departmental special consideration listed below). Insulin Pump Pregnancy Peri-Operative ICU Pediatrics DKA Abrupt or unplanned alteration of pump regimen can result in rapid deterioration of metabolic control resulting in acute complications, (DKA, hypoglycemia) and adverse outcome. Accordingly, any change in regimen should only be ordered by or in consultation with the primary diabetes physician. Lack of optimal glycemic control in pregnancy has been shown to cause significant and life-threatening complications for both mother and child. Consultation should be obtained with any admissions of pregnant patient with diabetes.* Preprandial BG goal of 60-90 and post-prandial BG goal of <120 has been shown to enhance outcomes of this populace. Optimal glycemic control will reduce post-operative complications and therefore patients with hyperglycemia may benefit from consultation and the use of IV insulin infusion. Maintaining BG levels of 80-140 has been shown to be effective in this setting. Optimal glycemic control reduces both morbidity and mortality rates in the ICU setting. Maintaining BG levels of 80-110 have been shown to benefit patients in the ICU area of care. The tendency toward labile blood sugars and special considerations related to managing diabetes in pediatric patients may result in compromised outcomes and therefore may well benefit from consultation. Since DKA is a serious condition which requires intensive management, consultation with the patient’s primary diabetes physician should be considered.* Hospital Diabetes Plan (cont’d) Protocol for insulin in hospitalized patient • Treat any patient with BG >140 mg/dL with insulin — Treat any BG >140 mg/dL with rapid-acting insulin (BG-100) / (3000 / wt [kg]) or 1700 / total daily insulin — Treat any recurrent BG >180 mg/dL with IV insulin if failing SC therapy or >140 mg/dL if NPO, acute MI, perioperative, ICU, or >100 mg/dL if pregnant • If >0.5 U/h IV insulin required, start long-acting insulin Hospital Diabetes Plan (cont’d) Protocol for insulin in hospitalized patient • Daily total: Pre-admission or weight (kg) x 0.5 U — 50% as glargine (basal) — 50% as total rapid-acting insulin (bolus) • Give in proportion to meal’s CHO eaten • BG >140 mg/dL: (BG-100) / CF — CF = 1700 / total daily insulin or 3000 / wt (kg) • Do not use sliding scale as only diabetes management Hospital Diabetes Plan (cont’d) What can we do for patients admitted to the hospital? • Get diabetes education consult • Instruct patient in monitoring and recording — See that patient has meter on discharge • Decide on case-specific program for discharge • Arrange early follow-up with PCP Questions • For a copy or viewing of these slides, contact or hospital protocols, go to: www.adaendo.com www.gha.org
