About this study

Official title: A Randomized, Controlled Trial to Compare the Effectiveness of SMS Text Message Reminders Compared to Usual Care to Increase Adherence to the Gardasil Vaccine Dosing Schedule (GCC 1063GCC).

Human papillomavirus (HPV) is the most common sexually transmitted disease among adolescent females in the United States. Our primary objective is to determine if Short Message Service (SMS) text message reminders increase adherence to the recommended 3 dose schedule for Gardasil compared to usual care in an outpatient clinic setting. Secondary objectives of this study are: 1) to demonstrate the feasibility of using SMS text message reminders to increase adherence with Gardasil vaccination; and 2) to assess satisfaction and acceptability of text message reminders compared to telephone reminders among women who receive the text message arm of the intervention. The investigators hypothesize that receiving SMS text message reminders will increase adherence to the recommended 3 dose schedule for Gardasil compared to usual care.

Read the detailed description

Technological innovations such as Short Message Service (SMS) text messages reminders are one strategy that may be used to increase adherence to the Gardasil dosing schedule. Although the literature in this area is in its infancy, several studies have demonstrated that SMS text reminders are an effective strategy for reducing nonattendance with medical appointments. Further, SMS text message reminders have been shown to be popular with patients and more cost-effective than paper or telephone-based reminder strategies. The investigators believe SMS text message reminders can be used as a feasible and cost-effective strategy to increase adherence to the Gardasil vaccine schedule, thus reducing risk of cervical cancer.

Women who are enrolled will be randomly assigned to one of 2 study groups (Usual Care v. SMS Text Message group). For women in the SMS Text Message group, text message reminders will be sent once per day for each of the seven days prior to the scheduled date for each of their follow up vaccinations. Participants follow the usual practices for scheduling their follow up visit(s) for vaccination at the clinic. Participants in both the Usual Care group and the SMS Text Message group will receive the standard reminder from the clinic for their scheduled appointment(s) (phone call, letter, etc, as appropriate). At enrollment, the participant will answer questions regarding social and demographic history, cell phone use patterns, attitudes and acceptance of HPV vaccine, gynecologic and sexual history.

All participants will be sent a packet of self-report measures to complete regarding attitudes toward HPV vaccination at the completion of the study. Participants in the SMS Text Message group will also receive rating scales to assess acceptability of text message reminders and preference for text message reminders over telephone reminders.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SMS Text MessageBehavioural

    Also called Usual care, Text message

    Women in the SMS Text Message group that reschedule a vaccination visit will receive text message reminders one per day for each of the seven days prior to the rescheduled visit (or as many days as possible depending on when the rescheduled visit will take place - for example, if they call in and reschedule the visit to take place in 4 days, they will receive text messages for the 3 days prior to the rescheduled visit). Participants in both the Usual Care group and the SMS Text Message group will receive the standard reminder from the clinic for their re-scheduled appointment(s).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants That Adhered to Vaccine Schedule

    Our primary objective is to determine if Short Message Service (SMS) text message reminders increase number of participants that adhered to the recommended 3 dose schedule for Gardasil compared to usual care in an outpatient clinic setting.

    Measured: at the end of the study (30 days after the third vaccination or 360 days after the first vaccination, whichever comes first)
