Description
Vaccine hesitancy is on the rise in the United States due to multiple factors. Causes of vaccine hesitancy in pediatric patient populations include fear of harmful side effects due to misinformation and social media (Lafnitzegger, A) as well as questioning the necessity of vaccination (Cataldi, J). Previous efforts to increase rates of pediatric vaccination include community efforts such as partnering with faith-based organizations in an attempt to campaign for increased vaccination rates (Crosby, L), as well as acknowledging the need to tackle the pain and fear of needles associated with vaccinations in pediatric populations (Taddio, A).
In the city of Philadelphia, Vaccines For Children publishes yearly data on vaccine rates. The vaccination rate for children ages 2 months to 3 years old is 68%, PCOM Lancaster Healthcare Center’s rate is 29%. The population of PCOM Healthcare Center is predominantly African-American and low socioeconomic status. We aim to improve vaccination rates in our patient population by placing telephone call reminders to schedule well visits and become up to date on vaccines. We performed telephone call reminders for patients from December 2025-November 2025. The study included patients that were between the ages of 2 months to 35 months as of November 1, 2024 and had repeated visits at the PCOM Lancaster Clinic between November 1, 2024 and November 1, 2025. Patients were excluded from the study if they were fully up to date on their vaccine schedule prior to the study start, did not receive a phone call from the office inviting them to come in to get vaccinated, or were only seen in office once between November 1, 2024 and November 1, 2025.
This study will elucidate the efficacy of phone call interventions in increasing vaccine compliance rates in our patient population and also across pediatric clinics in the United States. This study will allow clinicians to assess and potentially implement a similar phone calling strategy to increase the vaccine compliance rates of their clinic.
