Description

This measure assesses the number of inpatient hospital days for patients age 18 and older with a hyperglycemic event (harm) per the total qualifying inpatient hospital days for that encounter

Measure Scoring Ratio measure
Measure Type Outcome
Stratification

None

Risk Adjustment

None

Rationale

Hyperglycemia, i.e., elevated glucose level, is common among hospitalized patients, especially those with preexisting diabetes (Umpierrez et al., 2012) and accounts for over 30% of noncritically ill hospitalized patients (Korytkowski et al., 2022). Hyperglycemia can also affect...

Clinical Recommendation Statement

Multiple guidelines address recommended levels of glycemic control, though these do not define severe hyperglycemia:

From Section 16, Diabetes Care in the Hospital, in the Standards of Care in Diabetes by the American Diabetes Association (American Diabetes Association Professional...

Improvement Notation

Decreased score indicates improvement

Definition

Inpatient hospitalizations: Includes time in the emergency department (ED) and observation when the transition between these encounters (if they exist) and the inpatient encounter are within an hour or less of each other.

This measure defines a day with a hyperglycemic event (harm) as...

Guidance

The measure is using mg/dL as the unit of measurement for glucose results. Millimoles per liter (mmol/L) should be converted to milligrams per deciliter (mg/dL) for reporting this measure.

When evaluating for days with a glucose level >300 mg/dL, the first 24-hour period after admission...

Initial Population

Inpatient hospitalizations for patients age 18 and older that end during the measurement period, as well as either:

- A diagnosis of diabetes that starts before the end of the encounter; or

- Administration of at least one dose of insulin or any hypoglycemic medication that starts during...

Denominator

Equals Initial Population

Denominator Exclusions

Inpatient hospitalizations for patients with a glucose result of >600 mg/dL anytime between 1 hour prior to the start of the encounter to 6 hours after the start of the encounter.

-Inpatient hospitalizations for patients who have comfort care measures ordered or provided during the...

Numerator

Inpatient hospitalizations with a hyperglycemic event within the first 10 days of the encounter minus the first 24 hours, and minus the last period before discharge from the hospital if less than 24 hours.

A hyperglycemic event is defined as:

- A day with at least one glucose value >300...
