Metadata Title NHSN Glycemic Control, Hypoglycemia Initial Population Version 0.000.01 Identifier nhsnglycemiccontrolhypoglycemicinitialpopulation Experimental true Steward (Publisher) NHSN Description All inpatient encounters (including ED/Observation visits that end within 1 hour of the start of the inpatient encounter) for patients of all ages where at least one ADD was ordered or administered during the encounter that is during the measurement period. Purpose This measure has been developed to support improvement in clinical care. Copyright This measure and specifications are subject to further revisions. This performance measure is not a clinical guideline, does not establish a standard of medical care and has not been tested for all potential applications. THE MEASURES AND SPECIFICATIONS ARE PROVIDED “AS IS” WITHOUT WARRANTY OF ANY KIND. Measure Scoring Cohort Measure Type Outcome Rationale The NHSN Glycemic Control, Hypoglycemia module provides a mechanism for facilities to report inpatient medication-related hypoglycemia events, and to provide analytic reports based on these data to inform glycemic control quality improvement efforts and patient safety events. The primary objective of the NHSN Glycemic Control, Hypoglycemia module is to facilitate measurement and benchmarking of medication-related hypoglycemia events within a facility. As additional data are collected by NHSN, an additional objective will be to facilitate inter-facility benchmarking and evaluate national-level trends of medication-related hypoglycemia over time. The IP dQM provides the initial population and FHIR line-level data necessary for calculating the module metrics. Measure Group (Rate) Initial Population ID: initial-population-01 Description: All inpatient encounters, as well as ED and OBS encounters that end within 1 hour of the start of the inpatient encounter, for patients of all ages where at least one antidiabetic drug (ADD) was ordered or administered during the encounter that is during the measurement period.

NHSN Glycemic Control, Hypoglycemia Initial Population
All inpatient encounters (including ED/Observation visits that end within 1 hour of the start of the inpatient encounter) for patients of all ages where at least one ADD was ordered or administered during the encounter that is during the measurement period.
This measure has been developed to support improvement in clinical care.
This measure and specifications are subject to further revisions. This performance measure is not a clinical guideline, does not establish a standard of medical care and has not been tested for all potential applications. THE MEASURES AND SPECIFICATIONS ARE PROVIDED “AS IS” WITHOUT WARRANTY OF ANY KIND.
The NHSN Glycemic Control, Hypoglycemia module provides a mechanism for facilities to report inpatient medication-related hypoglycemia events, and to provide analytic reports based on these data to inform glycemic control quality improvement efforts and patient safety events. The primary objective of the NHSN Glycemic Control, Hypoglycemia module is to facilitate measurement and benchmarking of medication-related hypoglycemia events within a facility. As additional data are collected by NHSN, an additional objective will be to facilitate inter-facility benchmarking and evaluate national-level trends of medication-related hypoglycemia over time. The IP dQM provides the initial population and FHIR line-level data necessary for calculating the module metrics.
Antidiabetic Drug Days (ADD): Aggregate number of inpatient encounter days within the facility in which at least one injectable or oral ADD was received. All patients who received ADDs during the hospitalization contribute to the initial population regardless of whether the patient experienced a hypoglycemic event.
Emergency Department (ED) or Observation (OBS) encounters: ED or observation encounters that ended within an hour of the inpatient admission are included when calculating the start and stop times of the hospitalization. Only Metric 1 includes ED and OBS encounters.
Hypoglycemia Day: An inpatient day with at least one documented hypoglycemia event.
Hypoglycemia Event includes the following during an inpatient hospitalization: A hypoglycemic blood glucose (BG) result during the encounter and ADD administered within 24 hours prior to the start of the hypoglycemic BG result and no subsequent test for blood glucose with a result ≥80 mg/dL within five minutes of the start of the initial low blood glucose test.
Inpatient Encounter: A hospitalization in any inpatient facility that meets the criteria for reporting to the NHSN Glycemic Control Hypoglycemia Module (refer to CDC Locations and Descriptions manual).
Measurement Period: From the first day of each calendar month through the last day of that calendar month. Mild hypoglycemia: Blood glucose 54 mg/dL to 69 mg/dL as identified on central laboratory device (CLD) or prescription point-of-care (POC) device.
Moderate hypoglycemia: Blood glucose 40 mg/dL to 53 mg/dL as identified on CLD or prescription POC device.
Severe hypoglycemia Blood glucose < 40 mg/dL as identified on CLD or prescription POC device.
All inpatient encounters, as well as ED and OBS encounters that end within 1 hour of the start of the inpatient encounter, for patients of all ages where at least one antidiabetic drug (ADD) was ordered or administered during the encounter that is during the measurement period.
