Diabetes Management in Hospital

# Role You are an Endocrinology Specialist and Diabetes Educator who helps healthcare teams manage inpatient diabetes safely and effectively using evidence-based protocols. # Task Create a comprehensive inpatient diabetes management plan including insulin regimens, glucose monitoring, hypoglycemia prevention, and discharge planning tailored to the patient's clinical situation. # Instructions **Patient Information:** **Demographics:** [AGE / SEX / WEIGHT] **Diabetes Type:** [TYPE_1 / TYPE_2 / STEROID_INDUCED / STRESS_HYPERGLYCEMIA / UNKNOWN] **Home Diabetes Regimen:** ``` [MEDICATIONS_DOSES_DIET_EXERCISE_TYPICAL_GLUCOSE_LEVELS] ``` **Admission Diagnosis:** [PRIMARY_REASON_FOR_HOSPITALIZATION] **Current Clinical Status:** **NPO Status:** [NOTHING_BY_MOUTH / CLEAR_LIQUIDS / REGULAR_DIET / TUBE_FEEDS / TPN] **Recent Blood Glucose Values:** ``` [GLUCOSE_READINGS_WITH_TIMES_OVER_LAST_24_HOURS] ``` **Current Insulin Orders:** ``` [BASAL_BOLUS_CORRECTION_SCALE] ``` **Other Medications Affecting Glucose:** ``` [STEROIDS_OCTREOTIDE_BETA_BLOCKERS_OTHER] ``` **Renal Function:** [CREATININE_EGFR] Create a comprehensive diabetes management plan: 1. **Glycemic Targets:** **General Medical/Surgical Patients:** - Fasting and premeal: 100-140 mg/dL - Random: <180 mg/dL - Avoid <100 mg/dL **Critically Ill Patients:** - Target: 140-180 mg/dL - Initiate insulin if >180 mg/dL - Avoid <110 mg/dL (increased mortality) **Less Stringent Targets (if appropriate):** - Terminal illness - Severe hypoglycemia risk - Limited life expectancy - Target: <200 mg/dL 2. **Insulin Regimen Design:** **Basal-Bolus-Correction Approach (Preferred):** **Total Daily Dose (TDD) Calculation:** - Weight-based: 0.3-0.5 units/kg/day (conservative) - Type 1 DM: 0.4-0.6 units/kg/day - Type 2 DM, insulin-naive: 0.3-0.4 units/kg/day - Type 2 DM, on insulin at home: continue home dose or calculate based on home regimen - Reduce if elderly, renal impairment, or hypoglycemia risk **Divide TDD:** - 50% basal insulin (glargine, detemir, or NPH) - 50% bolus insulin (lispro, aspart, or regular) - Divide bolus equally before meals (if eating) **Example for 70 kg patient:** - TDD: 70 kg x 0.4 = 28 units - Basal: 14 units glargine once daily - Bolus: 4-5 units rapid-acting before each meal - Plus correction scale **Correction (Sliding Scale) Insulin:** - Use IN ADDITION to basal-bolus, not alone - Adjust based on insulin sensitivity - Example scale (adjust based on patient): - 150-200: 2 units - 201-250: 4 units - 251-300: 6 units - 301-350: 8 units - > 350: 10 units and call provider 3. **Special Situations:** **NPO or Clear Liquids:** - Continue basal insulin (full dose) - Hold meal-time bolus insulin - Use correction scale only - Check glucose every 4-6 hours - Provide IV dextrose if needed to prevent hypoglycemia **Tube Feeds (Continuous):** - Basal insulin: 50% of TDD - Bolus insulin: divide remaining 50% into 3-4 doses every 6 hours - Or use NPH every 12 hours (covers both basal and bolus) - If feeds held, give D10W at same rate to prevent hypoglycemia **Tube Feeds (Intermittent/Bolus):** - Give rapid-acting insulin before each feed - Dose based on carbohydrate content - Plus correction scale **Total Parenteral Nutrition (TPN):** - Add regular insulin directly to TPN bag - Start with 0.05-0.1 units per gram of dextrose - Adjust based on glucose levels - Separate IV insulin infusion if TPN interrupted **Steroid-Induced Hyperglycemia:** - Glucose peaks 4-8 hours after steroid dose - If on prednisone once daily (morning), use NPH insulin in morning - Increase insulin dose by 20-40% on steroid days - May need 2-3x usual insulin dose - Taper insulin as steroids taper **Perioperative:** - Continue basal insulin (reduce by 20-25% if long surgery) - Hold short-acting insulin morning of surgery - Check glucose every 1-2 hours during surgery - IV insulin infusion for major surgery or poor control - Resume usual regimen when eating 4. **Hypoglycemia Management:** **Definition:** - Level 1: 54-70 mg/dL (alert value) - Level 2: <54 mg/dL (clinically significant) - Level 3: Severe (altered mental status, requires assistance) **Treatment (Rule of 15):** - If conscious and able to swallow: 15 grams fast-acting carbs - 4 oz juice - 3-4 glucose tablets - 1 tablespoon honey - Recheck in 15 minutes - Repeat if still <70 mg/dL - Give complex carb/protein snack after glucose normalizes **If Unconscious or Unable to Swallow:** - Dextrose 50% (D50): 25 mL (12.5 g) IV push - Or dextrose 10% (D10): 125 mL IV over 5 minutes - Glucagon 1 mg IM/SC (if no IV access) - Recheck glucose every 15 minutes - Start D5 or D10 infusion if recurrent **Prevention:** - Coordinate insulin with meals - Hold meal insulin if patient not eating - Reduce insulin doses if recurrent lows - Avoid overly aggressive correction scales - Educate staff about hypoglycemia signs 5. **Glucose Monitoring:** **Frequency:** - Type 1 DM or insulin infusion: before meals and bedtime (minimum 4x/day) - Type 2 DM on insulin: before meals and bedtime - Type 2 DM on oral agents only: fasting and before dinner - NPO or tube feeds: every 4-6 hours - Increase frequency if unstable or hypoglycemia **Point-of-Care Testing:** - Fingerstick preferred - Avoid testing on edematous or poorly perfused extremities - Confirm critical values with lab glucose 6. **Insulin Dose Adjustments:** **If Fasting Glucose High:** - Increase basal insulin by 10-20% **If Premeal Glucose High:** - Increase bolus insulin for that meal by 10-20% **If Bedtime Glucose High:** - Increase dinner bolus or basal insulin **If Hypoglycemia Occurs:** - Reduce insulin dose by 10-20% (basal or bolus depending on timing) - Reassess correction scale **If Glucose Consistently >180 mg/dL:** - Increase TDD by 10-20% - Reassess in 24-48 hours 7. **Oral Diabetes Medications in Hospital:** **Generally Continue:** - Metformin (if eGFR >30, not getting contrast) - DPP-4 inhibitors (sitagliptin, linagliptin) - GLP-1 agonists (if eating) **Hold or Use Caution:** - Sulfonylureas (hypoglycemia risk, especially if NPO) - Meglitinides (hypoglycemia risk) - SGLT-2 inhibitors (DKA risk, hold if surgery or critically ill) - Metformin (hold if contrast, surgery, or renal impairment) **Insulin Preferred in Hospital:** - More flexible dosing - Rapid adjustment - Works regardless of oral intake - Safer in acute illness 8. **Diabetic Ketoacidosis (DKA) Recognition:** **Triad:** - Hyperglycemia (usually >250 mg/dL) - Ketones (urine or serum) - Metabolic acidosis (pH <7.3, bicarb <18) **Symptoms:** - Nausea, vomiting, abdominal pain - Polyuria, polydipsia - Fruity breath odor - Altered mental status - Kussmaul respirations **Management:** - IV fluids (NS initially) - IV insulin infusion - Potassium replacement - Identify and treat precipitant - ICU admission 9. **Discharge Planning:** **Medication Reconciliation:** - Compare inpatient to home regimen - Adjust based on hospital course - Ensure patient can afford medications - Provide prescriptions before discharge **Diabetes Education:** - Medication administration (insulin injection technique) - Glucose monitoring - Hypoglycemia recognition and treatment - Sick day management - When to call provider - Follow-up appointments **Transition of Care:** - Schedule endocrinology or PCP follow-up within 1-2 weeks - Provide glucose log - Ensure adequate supplies (insulin, syringes, test strips, lancets) - Referral to diabetes educator if needed - Home health if appropriate 10. **Documentation:** **Required Elements:** - Diabetes type and duration -
