Thank you for your inquiry specific to CMS816v2/v3 Hospital Harm - Severe Hypoglycemia. To clarify, the measure logic does not require that a repeat glucose test be performed. As documented in the ‘Definition’ of the eCQM specification, located on the eCQI Resource Center ( https://ecqi.healthit.gov/): The measure does not count a severe hypoglycemic event (harm) in the numerator if there is a repeat test for glucose with a result greater than 80 mg/dL within five minutes of this initial low glucose test. The purpose of the repeat test within 5 minutes is to eliminate false positives that can occur in POC testing. The 5-minute timeframe extends from the start of the severe hypoglycemic test to the time of the repeat hypoglycemic test. The measure intent is to identify and remove false positives that can occur in POC testing to ensure hospitals are not penalized for erroneous results that can occur from POC testing. The expectation is that in most cases of severe hypoglycemia, the clinical team will be treating the patient and will not immediately repeat the test. However, if the severe hypoglycemic event (i.e., glucose level < 40 mg/dL) is suspected to be a false positive, for example if the patient is clinically asymptomatic, and a repeat test is performed which results in a blood glucose level of >80 mg/dL (i.e., not a severe hypoglycemic event), this will confirm that suspicion, and the numerator will not be met. The 5-minute window extends from the time that the initial blood glucose test was drawn to the time that the repeat blood glucose test was drawn, as the draw time (not the time of the result) reflects the time the patient was experiencing a specific blood glucose level. We hope this provides greater clarity for you and your team.
