Percentage of cases with glucose < 70mg/dL, treated with administration of dextrose containing solution or glucose recheck within 30 minutes of original glucose measurement.

The American Diabetes Association uses an outpatient hypoglycemia definition of <70 mg/dL^6,7. Severe hypoglycemia in inpatients is considered <40mg/dL⁶. Acute hypoglycemia in the perioperative period can lead to inadequate supply of glucose to the brain, resulting in seizures, permanent brain damage, and death.  In hospitalized diabetic patients, hypoglycemia has been associated with increased length of stay and mortality.⁵ The risk of negative sequelae related to hypoglycemia is reduced with early recognition and treatment of mild to moderate hypoglycemia (40-69mg/dL)^6,8,9. The common signs/symptoms of hypoglycemia are masked by general anesthesia, making vigilance and quick treatment especially important.¹ Fasting patients with or without diabetes and diabetic patients treated with oral glycemic agents or insulin are at increased risk of perioperative hypoglycemia.^2-3

Perioperative hypoglycemia is a rare event typically caused by the following: ⁴

1. Insulin overdose, either by patient taking higher than normal doses on the morning of surgery or by providers giving more insulin than necessary
2. Septic or circulatory shock
3. Failure to monitor

Anesthesia Start to Anesthesia End.

• All patients with glucose level less than 70 mg/dL between Anesthesia Start and Anesthesia End
• Patients with and without diagnosis of diabetes

• ASA 5 & 6 including Organ Procurement (CPT: 01990)
• Glucose measurements < 70 mg/dL within 30 minutes before Anesthesia End  
• Labor Epidurals (determined by the Obstetric Anesthesia Type value codes: 3&6 including obstetric non-operative procedures - CPT: 01958) 

• Administration of dextrose containing solution within 30 minutes (IV)  OR

• Recheck of glucose level within 30 minutes

• All values mapped to glucose MPOG concepts with SI units (mmol/L) will be converted to mg/dL (mmol/L * 18.018 = mg/dL)

*This measure will include valid MPOG cases defined by the Is Valid Case MPOG phenotype.

Not applicable

Provider(s) signed in at the first glucose recheck or first administration of dextrose. If neither occurred, then the provider(s) signed in 30 minutes after the low glucose measurement.
