Experimental: Increasing flu vaccination
Collect from billing records in the 10 intervention practice sites to test for an increase in the rate of receipt of ≥1 influenza vaccine during the post-intervention year compared to the pre-intervention year among children 6 months to 18 years during the season. The interventions include: 1. Develop practice-based intervention strategies (like use of reminder-recall of children due for influenza,2. Develop Private/public collaboration to increase flu vaccination between the intervention practices, their county public health department and visiting nursing associations, and 3. Implement both practice-based and private-public collaborative strategies in the intervention practices while monitoring only in the control practices
Behavioral: Private/public collaboration to increase flu vaccination
Intervention practices will develop office-based interventions including methods to identify high-risk patients within their practices and methods of maximizing the immunization of these children within the practice, use of patient reminders, after-hours influenza clinics, walk-in provision of influenza vaccine and increased focus on education regarding the need for immunization. The practices will also collaborate with their county public health departments and visiting nursing associations to develop private-public collaborative interventions that may include large clinics for school-aged children for multiple practices and tracking of influenza supplies and redistribution of influenza vaccine between practices when supplies are delayed or inadequate.
Patients in control practices will continue to receive usual care with no change in practice regarding influenza immunization delivery.
Other: Usual care
This group will continue administering influenza vaccine to their patients in their practice as they normally do.
- Evaluate the effectiveness of collaborations between public and private entities to increase influenza vaccination in children 6 mos to 18 yrs in 10 intervention sites in 3 counties throughout the state of CO during the '10-11 & '11-12 flu seasons. [ Time Frame: Up to 4 months post intervention (December 2012) ]Primary outcome measure is to increase the rate of receipt of ≥1 influenza vaccine during the post-intervention year(s) compared to the pre-intervention year among children 6 mos.-18 yrs in 10 intervention sites. Intervention practices will collaborate with their respective health departments and/or the VNA to help assist with the increase in volume of patients needing to be vaccinated against flu in the 2010-2011 and the 2011-2012 flu seasons. Billing data will be obtained from all 20 sites (intervention+control) and compared to evaluate the effectiveness of this collaboration.
- high-risk children receipt of influenza vaccination [ Time Frame: baseline and intervention years 1 and 2 ]increase in the rate of receipt of ≥1 influenza vaccine during the post-intervention year compared to the pre-intervention year among high-risk children
- high-risk children fully immunized during influenza season [ Time Frame: baseline and intervention years 1 and 2 ]increase in the rate of high-risk children who were fully immunized during the season.
