Vaccination Coverage of Adolescents With Chronic Medical Conditions.

Introduction: Adolescents with chronic medical conditions (CMCs) are at increased risk of vaccine-preventable infections. Little is known about their vaccine uptake.

Methods: This retrospective cohort study included 3,989 adolescents aged 11-17 years receiving care at academically affiliated pediatric clinics between August 2011 and June 2013.

Text message reminders for vaccination of adolescents with chronic medical conditions: A randomized clinical trial.

Background: Many adolescents with chronic medical conditions (CMCs) are at risk of vaccine-preventable infection, yet are frequently under-vaccinated. Text message reminders, particularly those with embedded educational information, have been shown to increase general pediatric vaccination. Their use has not been studied specifically among adolescents with CMCs.

Text message reminders for timely routine MMR vaccination: A randomized controlled trial.

Objective: Measles-mumps-rubella (MMR) vaccination is important for preventing disease outbreaks, yet pockets of under-vaccination persist. Text message reminders have been employed successfully for other pediatric vaccines, but studies examining their use for MMR vaccination are limited. This study assessed the impact of text message reminders on timely MMR vaccination.

Impacting delayed pediatric influenza vaccination: a randomized controlled trial of text message reminders.

Background: Influenza vaccination coverage is low, especially among low-income populations. Most doses are generally administered early in the influenza season, yet sustained vaccination efforts are crucial for achieving optimal coverage. The impact of text message influenza vaccination reminders was recently demonstrated in a low-income population.

Registry-linked electronic influenza vaccine provider reminders: a cluster-crossover trial.

Objective: To determine the impact of a vaccination reminder in an electronic health record supplemented with data from an immunization information system (IIS).

Methods: A noninterruptive influenza vaccination reminder, based on a real-time query of hospital and city IIS, was used at 4 urban, academically affiliated clinics serving a low-income population. Using a randomized cluster-crossover design, each study site had "on" and "off" period during the fall and winter of 2011-2012.

Text message reminders for second dose of influenza vaccine: a randomized controlled trial.

Objective: To determine whether provision of vaccine-health-literacy-promoting information in text message vaccine reminders improves receipt and timeliness of the second dose of influenza vaccine within a season for children in need of 2 doses.

Methods: During the 2012-2013 season, families of eligible 6-month through 8-year-old children were recruited at the time of their first influenza vaccination from 3 community clinics in New York City. Children (n = 660) were randomly assigned to "educational" text message, "conventional" text message, and "written reminder-only" arms.

MoSAIC: Mobile Surveillance for Acute Respiratory Infections and Influenza-Like Illness in the Community.

Surveillance for acute respiratory infection (ARI) and influenza-like illness (ILI) relies primarily on reports of medically attended illness. Community surveillance could mitigate delays in reporting, allow for timely collection of respiratory tract samples, and characterize cases of non–medically attended ILI representing substantial personal and economic burden. Text messaging could be utilized to perform longitudinal ILI surveillance in a community-based sample but has not been assessed.

Influenza vaccine text message reminders for urban, low-income pregnant women: a randomized controlled trial.

Objectives: We evaluated the impact of influenza vaccine text message reminders in a low-income obstetric population.

Methods: We conducted a randomized controlled trial that enrolled 1187 obstetric patients from 5 community-based clinics in New York City. The intervention group received 5 weekly text messages regarding influenza vaccination starting mid-September 2011 and 2 text message appointment reminders.

Effect of a text messaging intervention on influenza vaccination in an urban, low-income pediatric and adolescent population: a randomized controlled trial.

Context: Influenza infection results in substantial costs, morbidity, and mortality. Vaccination against influenza is particularly important in children and adolescents who are a significant source of transmission to other high-risk populations, yet pediatric and adolescent vaccine coverage remains low. Traditional vaccine reminders have had a limited effect on low-income populations; however, text messaging is a novel, scalable approach to promote influenza vaccination.
