Tailored interventions to introduce influenza vaccination among 6- to 23-month-old children at inner-city health centers

Am J Manag Care. 2005 Nov;11(11):717-24.

Abstract

Background: Because of high rates of hospitalization for influenza infections among very young children (< 2 years), the Advisory Committee on Immunization Practices initiated a new policy in 2002 that encouraged vaccination of healthy children aged 6 to 23 months against influenza.

Objective: To evaluate the effectiveness of implementing tailored interventions to introduce influenza vaccination of children 6 to 23 months of age in inner-city practices.

Study design: A before-after trial with historical and concurrent controls was conducted in 6 health centers in low-income urban locations.

Methods: Intervention sites were selected, and interventions (directed at 1534 patients who were 6 to 23 months old) were implemented from a menu of strategies. Vaccination rates were measured from medical record reviews. Focus groups of nursing staffs provided evaluative information on strategies.

Results: Influenza vaccination rates improved significantly at the intervention health centers compared with the control center. Preintervention (2001-2002) rates ranged from 0% to 7.6%, and intervention (2002-2003) rates ranged from 15.2% to 49.2% (P < .001). The number of interventions ranged from 6 to 11. Sites that used more interventions (odds ratio, 1.24; 95% confidence interval, 1.15-1.34) and had staff support of the vaccination effort (odds ratio, 1.91; 95% confidence interval, 1.40-2.60) had higher vaccination rates.

Conclusions: Tailored interventions resulted in successful introduction of influenza vaccination of 6- to 23-month-old children in inner-city health centers. More strategies and enthusiastic staff support may result in higher vaccination rates.
