GUIDANCE: 

To enable reporting of this measure at the close of the reporting period, this measure will only assess the influenza season that ends in March of the reporting period. The subsequent influenza season (ending March of the following year) will be measured and reported in the following year.


To account for the majority of reporting years' appropriate flu season duration, the measure logic will look at the first 89 days of the measurement period for the appropriate criteria and actions to be present/performed (January 1 through March 31). The measure developer believes it is best to keep the logic as static as possible from one reporting year to the next. Therefore, during leap years, only encounters that occur through March 30 will be counted in the denominator.


As a result of updated CDC/ACIP guidelines which include the interim recommendation that live attenuated influenza vaccine (LAIV) should not be used due to low effectiveness against influenza A(H1N1)pdm09 in the United States during the 2013-14 and 2015-16 seasons, the measure specifications have been updated and no longer include LAIV or intranasal flu vaccine as an option for numerator eligibility.
