Influenza and Text Messaging in Pregnancy

University of Pittsburgh216 enrolled

Overview

A randomized, controlled clinical trial to assess whether text messaging to an outpatient obstetric population can improve maternal influenza vaccine uptake.

History and the 2009 H1N1 influenza pandemic suggest that both seasonal and pandemic influenza infections impart disproportionate morbidity and mortality among gravidas. The influenza vaccine represents a viable, preventive health intervention to mitigate disease burden for gravidas and their neonates. Despite the safety and efficacy of influenza vaccines, suboptimal maternal vaccination rates (13-24%) persist nationwide. Barriers to influenza vaccination during pregnancy include patient concerns about vaccine safety and unappreciated risk of influenza infection. Cellular phone text messaging has emerged as an innovative technology with advantages of ubiquity, rapid, confidential information transmission, and low cost. Text messaging may represent an effective way to educate pregnant women about their particular vulnerability to influenza infection and enhance influenza vaccine uptake. We propose a randomized, controlled clinical trial to assess whether text messaging to an outpatient obstetric population can improve maternal influenza vaccine uptake.

Subjects assigned to the influenza information group will receive health text messages from the time they enroll until they deliver. These messages will contain general health information as well as information regarding influenza and the importance of vaccination during pregnancy.

Outcomes

Primary Outcomes

To assess the ability of direct communication and education to patients using modern technology (cellular text messaging) to enhance vaccine uptake.

To assess the ability of direct communication and education to patients using modern technology (cellular text messaging) to enhance vaccine uptake. We hypothesize that text messaging will improve the timing (earlier in flu season) and rate of receipt of influenza vaccination in pregnancy.

Time frame: at participant post-partum visit

Secondary Outcomes

To assess the ability of direct education via text messaging to enhance knowledge about influenza infection and vaccination in pregnancy.

To assess the ability of direct education via text messaging to enhance knowledge about influenza infection and vaccination in pregnancy. We hypothesize that women receiving text messages will be more likely than controls to have accurate knowledge about pregnant women's increased susceptibility to influenza and about the vaccine's safety and efficacy in pregnancy.

Time frame: at participant post-partum visit
