HPV Centralized R/R RCT #2 - New York State
|ClinicalTrials.gov Identifier: NCT03294551|
Recruitment Status : Active, not recruiting
First Posted : September 27, 2017
Last Update Posted : June 5, 2019
The work done in this trial builds off of the work previously conducted by this same research group in clinicaltrials.gov ID: NCT03057379. Due to some changes in study design, protocol, and cohort of interest, a new registration was warranted.
The overarching goal of this study is to evaluate the effectiveness, cost-effectiveness, and sustainability of utilizing statewide immunization information systems (IISs) to conduct centralized reminder recall (R/R) to improve human papillomavirus (HPV) vaccination rates among adolescents 11-14 years of age.
The latest recommendations from the ACIP, as of February 2017, modified the vaccination schedule for the HPV series for eligible adolescents ages 11-14. Adolescents who receive dose #1 between the ages of 11 and 14 are now eligible for their second and final dose 6-12 months after their initial dose. Despite U.S. guidelines for vaccinating all adolescents starting at age 11 with the HPV vaccine, in 2012 only 53% of 13-17 year old females had >1 dose and 35% had 3 doses; 21% of teen males had a vaccination. Modeling studies predict marked reduction in HPV associated cancers and in disparities in these cancers if high HPV vaccination rates can be achieved.
With this new dosing schedule for adolescents, the research team proposes to conduct a randomized control trial (RCT) utilizing the capabilities of the State Immunization Information System (IIS), and create a HPV-specific R/R autodialer and text message to be delivered to the parents of patients ages 11-14 of randomly selected practices within New York State (excluding NYC). Upon conclusion of this trial, researchers will develop a toolkit for dissemination so that other state IIS systems may replicate these centralized reminder recall procedures.

The overarching goal is to evaluate the effectiveness, cost effectiveness, and sustainability of statewide immunization systems (IISs) to conduct reminder/recall (R/R) to improve human papillomarvirus (HPV) vaccination rates among adolescents ages 11-14.
Each year, 6.2 million persons are newly infected with HPV and 26,000 new HPV-related cervical, genital, and oropharyngeal cancers are diagnosed, resulting in >$4 billion in annual medical costs. Despite U.S. guidelines for vaccinating all adolescents starting at age 11 with the HPV vaccine, in 2012 only 53% of 13-17 year old females had >1 dose and 35% had 3 doses; 21% of teen males had a vaccination.
The most effective strategy for improving vaccination rates is patient reminder/recall (R/R). Recent literature from Melissa Stockwell found that utilization of a new R/R modality, i.e. text messaging, positively impacted influenza vaccination rates among the adolescents enrolled in the study. Although R/R is already considered a "best practice" for improving vaccination rates, very few practices use reminder/recall for any vaccinations because of costs and lack of personnel time; and even fewer use reminder/recall for HPV vaccine.
Furthermore, since the Advisory Committee on Immunization Practices (ACIP) modified the schedule for the HPV series for adolescents' age 11-14 years, those who receive dose #1 between ages of 11 and 14 years are now eligible for their second and final dose 6-12 months after their initial dose. This change in dosing schedule could influence HPV vaccine visit scheduling procedures within Family Practice and/or Pediatric Clinics, and would therefore effect timing and frequency of any R/R strategies currently in place. Therefore, the UCLA (overseeing the work to be done in NY) and University of Colorado at Denver research teams unite to understand how the use of centralized R/R to disseminate reminders, via text messages and autodialer calls, to patients eligible for the 2-dose HPV vaccine could impact vaccination rates among adolescents ages 11-14. This will be the first head-to-head RCT comparing text message vs. autodialer reminders to standard of care control
The aim of the study is as follows:
To assess the impact and cost-effectiveness of autodialer IIS R/R versus text message based IIS R/R versus standard-of-care control (no reminder recall) in increasing initiation and completion of the 2-dose HPV vaccine series among adolescents 11-14 years of age. The investigators will use a within-practice randomized control trial, randomizing patients within 150 practices to the aforementioned intervention arms.
Hypothesis 1: All centralized IIS R/R modalities will be more effective than usual care
Hypothesis 2: Text messaging will be more cost-effective than other modalities
Upon completion of the study, the investigators will have a feasible, sustainable, cost-effective model for HPV vaccination reminders that could be scaled up on the national level to help prevent HPV-related cancers. Additionally, this research will be adding significant new knowledge to the field as no such studies exist examining the impact of educational text message R/R on HPV vaccination rates among adolescents eligible for the 2-dose series.

No Intervention: Standard of Care Control
Usual source of care
Experimental: HPV Vaccine Reminder Recall - Autodialer
HPV Vaccine Reminder Recall - Autodialer: Receive up to 4 reminders via telephone (live call or voicemail) - includes brief educational message + providers name + providers telephone number
Behavioral: HPV Vaccine Reminder Recall - Autodialer
Investigators will send out HPV vaccine reminder recall notices via autodialer message to the parents of adolescents 11-14 years of age who are eligible to receive a dose of the HPV vaccine per the records in the New York State Immunization Information System (NYSIIS). The investigators will be testing the effectiveness and cost effectiveness of the various modalities or reminders as compared to the standard of care control (no reminders)
Experimental: HPV Vaccine Reminder Recall - Texting
HPV Vaccine Reminder Recall - Texting: Receive up to 4 reminders via text message - includes brief educational message + providers name + providers telephone number
Behavioral: HPV Vaccine Reminder Recall - Texting
Investigators will send out HPV vaccine reminder recall notices via text message to the parents of adolescents 11-14 years of age who are eligible to receive a dose of the HPV vaccine per the records in the New York State Immunization Information System (NYSIIS). The investigators will be testing the effectiveness and cost effectiveness of the various modalities or reminders as compared to the standard of care control (no reminders)
- Initiation of the HPV 2-dose series [ Time Frame: 5 months from the first reminder received for the first dose of HPV vaccine ]Receipt and documentation of the initial dose of the vaccine within the series as recorded in the NYSIIS database. Investigators are allowing 5 months after the initial reminder recall was sent as the timeline of attributing vaccination status to the intervention
- Completion of the HPV 2-dose series [ Time Frame: 5 months from the first reminder received for the last dose of HPV vaccine ]Receipt and documentation of the final dose of the vaccine series as recorded within the NYSIIS database. Investigators are allowing up to 5 months after the first reminder recall for the second dose was received. If vaccination is received after that 5 month period, investigators will not attribute change in vaccination status to the reminder.
- Cost of the R/R intervention - autodialers and texting [ Time Frame: 17 months - entirety of the trial ]A cost-effectiveness analysis will be conducted to determine which modality of R/R (autodialer or text message) is the most cost-effective in relation to improving HPV vaccination rates among 11-14 year old adolescents as compared to the control, as well as comparing the two interventions arms to one another.
