      Thank you for your inquiry about CMS117v12, Childhood Immunization Status. The intent of the measure is to include patients who have had either the HiB 3 dose regimens or Hib 4 dose regimens. The logic for the "Has Appropriate Number of Hib Immunizations" will first check to see if a patient has at least 4 doses of either the 4-dose or 3-dose HiB vaccine. If a patient does not have at least 4 doses of the HiB vaccine, the logic will then evaluate to see if the patient has at least 3 doses of the 3-dose HiB vaccine. We will consider updates to the measure logic in a future annual update cycle.

    • Disconnect between measure definition and logic provided to Epic resulting in patients not meeting the metric for Hib non-compliance when patients did complete the appropriate # of Hib vaccines. Resulting in overall decreased (and inaccurate) performance

      Percentage of children 2 years of age who had four diphtheria, tetanus and acellular pertussis (DTaP); three polio (IPV), one measles, mumps and rubella (MMR); three or four H influenza type B (Hib); three hepatitis B (Hep B); one chicken pox (VZV); four pneumococcal conjugate (PCV); one hepatitis A (Hep A); two or three rotavirus (RV); and two influenza (flu) vaccines by their second birthday
       
      Pt DOB 3/13/2022.
      HiB (Pedvax Hib LIM 86)- administered 5/20/2022
      Hib (Pedvax Hib LIM 86)- administered 7/22/2022.
      Dtap/IPV/Hepb/Vaxelis (LIM 43)- administered 8/4/2023
      The 8/4/2023 dose is the booster dose, Vaxelis. As per CDC guidelines, a booster dose can be any licensed conjugate HIB vaccination adminstered at age 12-15 months. The booster dose will be dose 3 or 4 depending on vaccine type used in primary series. THis patient's primary series was the 2-dose series of PedvaxHIB. Therefore the 3rd Vaxelis HIB dose should complete their HIB series (3-doses).
       
      However, the CMS CQL logic is written in a way that it would not consider the previous two dose series of PedvaxHIB because they have received a vaccination that is a part of a 4 dose series (under the CVX code associated with the LIM record).
       
      The CMS CQL logic first checks all the unique Hib administrations a patient has received. If any of those administrations is linked to a CVX code defined as a 4 dose series , then there must be 4 unique administrations. Otherwise, 3 will be passing criteria.
      It seems to be the logic should look at the CVX code of the first chronological dose (of the primary series). Not ANY of the doses.
