Well-Child Visits in the First 30 Months of Life (W30)

This Healthcare Effectiveness Data and Information Set (HEDIS®)1 measure looks at the percentage of members who had well-child visits with a primary care provider during the previous 15 months. The following rates are reported:

  • Well-child visits for children who turned age 15 months during the measurement year and had six or more well-child visits
  • Well-child visits for children who turned age 30 months during the measurement year and had two or more well-child visits

Who was measured?
PrimeWest Health members ages 0 – 30 months during the measurement year who were continuously enrolled during the measurement year with no more than one 45-day gap in enrollment were measured. 

What can providers do?
If a child comes in for a sick/problem-based visit, providers are encouraged to turn it into a full child well-care visit that includes a health history, physical and mental developmental histories, a physical exam, and anticipatory guidance. A good resource for anticipatory guidance at specific ages is the Bright Futures website sponsored by Georgetown University.
