Adult Influenza Vaccination Text Message Reminders With Electronic Health Record Alerts

Influenza infection leads to on average 3000-49,0000 deaths and 150,000 hospitalizations
annually. While vaccination is the cornerstone of preventing influenza infection,
vaccination coverage in adults is low. Latino adults have the lowest coverage rates. Text
message reminders have been used successfully for improving influenza vaccination for
children. This study will assess the use of text messaging to improve influenza vaccination
coverage rates in a largely minority, publicly insured adult population. We will also assess
if the patient having received a text message makes the patient more likely to accept
vaccination when their provider has received in electronic alert regarding need for
influenza vaccination in the electronic health record.
