Influenza and Text Messaging in Pregnancy

Not Applicable

Completed

• Conditions: Pregnancy
• Interventions: Other: general health information; Other: influenza and general health information

• Registration Number: NCT01248520
• Lead Sponsor: University of Pittsburgh

Brief Summary

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

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
General health information	general health information	Pregnant women receiving text messages containing general health messages without including information regarding the importance of the influenza vaccination
Influenza and general health information	influenza and general health information	Pregnant women receiving text messages with influenza facts and the importance of the influenza vaccination, as well as general health messages Intervention: Text messages with influenza facts

Primary Outcome Measures

Name	Time	Method
To assess the ability of direct communication and education to patients using modern technology (cellular text messaging) to enhance vaccine uptake.	at participant post-partum visit	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.

Secondary Outcome Measures

Name	Time	Method
To assess the ability of direct education via text messaging to enhance knowledge about influenza infection and vaccination in pregnancy.	at participant post-partum visit	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.
