Health Professions Act Revised Hypoglycemia Protocol Insulin Subcutaneous Sliding Scale Anar Dossa BScPharm CDE September 14, 2007 HPA-Health Professions Act What is it? Regulatory framework for health professionals Basic requirements for regulating every health profession are similar Accountability for standards of practice Quality assurance measurements Rigorous registration process Mechanism to review public concerns HPA-Health Professions Act Nursing Implications Increase in scope of practice for registered nurses effective July 1, 2006 Allows registered nurses to initiate certain patient care activities without a doctor’s order HPA-RN Scope of Practice WITHIN SCOPE CRNBC CERTIFIED PRACTICE OUT OF SCOPE Nursing practice activities Vital signs Not reserved actions Current Practice Reserved actions Reserved Reserved without an order actions with actions for an order CRNBC certified Hypoglycemia: practice initiate IV access & medications Section 8 July 1, 2006 Reserved actions outside scope of practice NP & Section 9 Section 10 Delegated July 1, August Fn 2006 2007 CRNBC Standards, Limits & Conditions crnbc 2006 Controls on Practice CRNBC 2006 Provincial Pilots •VCH: Hypoglycemia, Wound Care, IV, Tylenol, Oxygen,Catheter •IHA: Venipuncture initiation •NHA: Catheter initiation •VIHA: Oxygen initiation •FH Wound Care Hypoglycemia Protocol Hypoglycemia is defined as blood sugar less than… Hypoglycemia Protocol Risk factors for hypoglycemia Nutritional status Missed meals, delayed meals Heart failure, renal or liver disease Malignancy Sudden reduction of steroid dose Altered ability of patient to report symptoms Vomiting Hypoglycemia Protocol Risk factors for hypoglycemia New NPO status Reduction in IV dextrose Unexpected interruption of feeds/TPN Altered consciousness from anesthesia Advanced age Previous history of severe hypoglycemia Symptoms Variable from patient to patient Assess patient for his/her individual symptoms Symptoms Trembling Palpitations Sweating Anxiety Nausea Hunger Tingling Clinical Practice Guidelines Can J Diabetes Dec 03 www.diabetes.ca Symptoms Confusion Difficulty concentrating Weakness Drowsiness Vision changes Difficulty speaking Headache Dizziness Tiredness Clinical Practice Guidelines Can J Diabetes Dec 03 www.diabetes.ca Symptoms Night Crying out Night sweats Morning headache Nightmares Symptoms-severe Unresponsive Unconscious Coma Seizure Hypoglycemia Unawareness No warning signals First sign may be loss of consciousness Confusion Hypoglycemia in the Elderly Reduced release of epinephrine and glucagon Cognitive impairment May not be able to communicate in timely manner Beta-blockers and Hypoglycemia What is the concern? Not an absolute contraindication Hypoglycemia Protocol Section A Conscious and able to swallow Section B Conscious but NPO or unable to swallow Tube fed/TPN Section C Unresponsive, unconscious, seizuring Where will these items be kept? D10W D50W Omnicell machine Glucagon Stores item, units to order via stores Omnicell machine Dextrosol Stores item NIA Section 8: Hypoglycemia Section 8 (1) Perform venipuncture for the purpose of: Establishing intravenous access, maintaining patency or managing hypoglycemia Administer a solution by instillation parenterally. RN Assess Pt. Diagnose Condition Condition: Hypoglycemia Policy/Patient Care Guideline Nurse Initiated Activity: Document Assessment Initiate Glucagon or IV insertion IV Solution Contraindications: PCG Contact Physician Pharmacy: Processes NIA Records Glucagon or D50W on MAR RN accountable to anticipate & monitior outcomes Physician aware within 4 hrs Follow Up Why did hypoglycemia occur? Should the dose of insulin or oral agent be adjusted? Insulin Subcutaneous Sliding Scale Refer to pre-printed order When should an insulin sliding scale be used? Supplement regularly scheduled insulin or oral diabetes medications May be used as a dose finding strategy Goal is to use as little sliding scale insulin as possible When should this sliding scale not be used? Diabetic ketoacidosis Intravenous insulin Insulin Sliding Scale Scheduled insulin plus Supplemental insulin Correction-dose insulin Dose-finding strategy Accommodate rapid changes in insulin requirements If correction doses are frequently required, change scheduled dose Which sliding scale? Low Intermediate High Custom Low Low or unknown insulin resistance High or unknown insulin sensitivity How do you determine this? Insulin Resistance Determination Insulin Dose (Total Daily Dose) < 0.5 units/kg Resistance Level 0.5 – 1 unit/kg Intermediate > 1 unit/kg High Low Low Resistance Thin NPO Renal Failure Elderly High Resistance Obese Insulin Sliding Scale Always use regular insulin Do not give at hs Why? Exception See protocol Follow Up Evaluate total dose q24-48hrs Does the basic dose need to be adjusted? New Insulins on Formulary Insulin Aspart NovoRapid® Rapid acting insulin analogue Bolus insulin Insulin Glargine Lantus® Long acting insulin analogue Basal insulin Insulin Aspart Must be given immediately prior to meals Within 15 minutes Risk of hypoglycemia if meal is delayed Can be mixed with NPH as long as the manufacturer is the same Inject immediately after mixing Cannot be given IV Insulin Glargine Cannot be given IV Clear solution Do not confuse with regular or aspart Cannot be mixed with anything Formulary Status Both insulins are restricted Endocrinology For Type 1 patients who experience hypoglycemia or inadequate control on Regular/NPH For patients on these insulins prior to admission Action Profiles of Bolus & Basal Insulins lispro/aspart 4–6 hours regular 6-10 hours BOLUS INSULINS BASAL INSULINS NPH 12–20 hours detemir ~ 6-23 hours (dose dependant) glargine ~ 20-26 hours Hours Note: action curves are approximations for illustrative purposes.
