What this trial studies

This study aims to assess whether a stakeholder-informed, standardized inpatient vaccination program can enhance influenza vaccination rates among hospitalized children in various U.S. pediatric health systems. Initially, a multidisciplinary team will be formed to create a best practice implementation guide for the vaccination program. Following this, the program will be piloted across three sites, and its effectiveness will be evaluated using an adaptive trial design across 12 health systems. The study will utilize established frameworks to measure the program's impact on vaccination rates.

Why it matters

Potential benefit: If successful, this program could significantly increase influenza vaccination rates among hospitalized children, leading to better health outcomes.

How similar studies have gone: Other studies have shown success with similar vaccination programs, indicating potential for positive outcomes in this approach.
