Hospital Harm - Severe Hypoglycemia

Receive updates on this topic

Measure Information 2023 Reporting Period
CMS eCQM ID CMS816v2
Short Name HH-01
NQF Number 3503e
Description

Inpatient hospitalizations for patients 18 years of age or older at admission, who were administered at least one hypoglycemic medication during the encounter, who suffer the harm of a severe hypoglycemic event during the encounter
Initial Population

Inpatient hospitalizations where the patient is 18 years of age or older at the start of the encounter, and at least one hypoglycemic medication was administered during the encounter.

The measure includes instances of administration of hypoglycemic medications in the emergency department or in observation status at the start of an inpatient hospitalization when assessing inclusion of encounters in the measure denominator.
Numerator

Inpatient hospitalizations where a severe hypoglycemic event occurred during the encounter, which is:

1. A blood glucose result less than 40 mg/dL

AND

2. A hypoglycemic medication administered within 24 hours prior to the start of the severe hypoglycemic event (i.e., the glucose result less than 40 mg/dL)

AND

3. No subsequent repeat test for blood glucose with a result greater than 80 mg/dL within five minutes of the start of the initial blood glucose test with result less than 40mg/dL

Only the first qualifying severe hypoglycemic event is counted in the numerator, and only one severe hypoglycemic event is counted per encounter. The 24-hour and 5-minute timeframes are based on the time the blood glucose was drawn, as this reflects the time the patient was experiencing that specific blood glucose level

Guidance

Note the measure is currently confined to using mg/dL as the unit of measurement for glucose results.

To calculate the hospital-level measure result, divide the total numerator events by the total number of qualifying inpatient hospitalizations (denominator).

Only the first qualifying severe hypoglycemic event is counted in the numerator, and only one severe hypoglycemic event is counted per encounter.

This eCQM is an episode-based measure. An episode is defined as each inpatient hospitalization or encounter that ends during the measurement period.

This version of the eCQM uses QDM version 5.6. Please refer to the QDM page for more information on the QDM.

Note the measure is currently confined to using mg/dL as the unit of measurement for glucose results.

Glucose levels are determined by laboratory or point-of-care (POC) tests, including capillary/glucometer blood glucose tests, and by interstitial fluid specimens from continuous glucose monitors. Glucose test results from urine specimens are not considered.
