Percentage of patients aged 6 months and older seen for a visit between October 1 and March 31 who received an influenza immunization OR who reported previous receipt of an influenza immunization


The timeframe for the visit during the "Encounter, Performed: Encounter-Influenza" or "Procedure, Performed: Peritoneal Dialysis" or "Procedure, Performed: Hemodialysis" in the Population Criteria-Denominator, refers to the influenza season defined by the measure: October through March (October 1 for the year prior to the start of the reporting period through March 31 during the reporting period). The "Encounter-Influenza" Grouping OID detailed in the data criteria section below is comprised of several individual OIDs of different encounter types. The individual OIDs are included in the value set and should be reviewed to determine that an applicable visit occurred during the timeframe for "Encounter, Performed: Encounter-Influenza" as specified in the denominator. 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.

Annual influenza vaccination is the most effective method for preventing influenza virus infection and its complications. Influenza vaccine is recommended for all persons aged >=6 months who do not have contraindications to vaccination.

Clinical Recommendation Statement

Routine annual influenza vaccination is recommended for all persons aged >= 6 months who do not have contraindications. Optimally, vaccination should occur before onset of influenza activity in the community. Health care providers should offer vaccination by October, if possible. Vaccination should continue to be offered as long as influenza viruses are circulating. (CDC/ACIP, 2015)


Previous Receipt - receipt of the current season's influenza immunization from another provider OR from same provider prior to the visit to which the measure is applied (typically, prior vaccination would include influenza vaccine given since August 1st)
