Insights
Tennessee faces low childhood vaccination rates, ranking in the bottom 25th percentile. The SmartSHOTS mobile app was developed to address these barriers for children aged 0-24 months, offering resources and tracking tools.
Area of Science:
- Public Health
- Health Informatics
- Mobile Health (mHealth)
Background:
- Tennessee exhibits low childhood vaccination rates, falling in the bottom 25th percentile nationally for children aged 0-24 months.
- Barriers to timely immunizations contribute to suboptimal vaccination coverage in the state.
Purpose of the Study:
- To develop and evaluate the usability of the SmartSHOTS mobile application.
- To reduce vaccination barriers for children aged 0-24 months in Tennessee.
Main Methods:
- Iterative design process informed by a needs assessment with Tennessee community members and county health council representatives.
- Usability testing of the SmartSHOTS mobile application with parents/guardians of children aged 0-24 months in Tennessee.
Main Results:
- The SmartSHOTS mobile app was developed, incorporating features such as vaccine information, due date tracking, and location services for health departments and transportation.
- Community members reviewed app wireframes, and parents/guardians evaluated the app's usability.
Conclusions:
- The SmartSHOTS mobile app presents a potential tool to mitigate vaccination barriers for young children in Tennessee.
- Further evaluation is needed to determine the app's impact on actual vaccination rates and health outcomes.
Abstract:
According to the Immunization Status Survey conducted by the Tennessee Department of Health in 2023, Tennessee ranks in the bottom 25th percentile among states for vaccination rates by the age of 24 months, based on the full series of recommended vaccines. To tackle this issue, the SmartSHOTS mobile application (mobile app) was developed to reduce vaccination barriers for children aged 0-24 months. The mobile app includes vaccine information, the ability to add and calculate vaccine due dates, and locating health departments and transportation services based on zip codes. The mobile app was developed and usability tested using an iterative design process, based on a needs assessment conducted across regions of Tennessee with community members who served on the state's county health council. These community members also reviewed the mobile app wireframes. Parents or guardians of children aged 0-24 months living in Tennessee evaluated the usability of the mobile app.
