Thank you for your inquiry. These encounters are in the initial population/denominator because the patients either have known diabetes, an elevated glucose level, or received pharmacotherapy for hyperglycemia during the encounter. However, when the LOS is less than 2 days, these days do not contribute to the denominator measure observation (i.e., eligible days) and therefore are excluded from the performance rate calculation.

Records with LOS less than 2 day do not have a calculated measure observation due logic "The first 24-hour period after arrival is not counted. The last day before discharge is not counted if it is > than 24 hours." What is the rationale for including these records if they will not have an associated calculated measure observation?
