About this study

Official title: Randomized Controlled Trial of an Automated, Managed Care-based Reminder/Recall System on Improving Rates of Immunization and Preventive Care Visits for Publically Insured Adolescents

The investigators will design and implement a randomized clinical trial to test, on a community-wide level, the effectiveness of managed care based tracking/reminder/recall on improving vaccination coverage among adolescents.

The investigators propose a randomized controlled trial to evaluate the effectiveness of reminder/recall for adolescents: 10,599 adolescents within the managed care organization (MCO) will be randomized into one of three arms: 1) mailed reminders, 2) autodialer telephone messages or 3) standard of care of their practice (no messages from the intervention).

Hypothesis 1: Reminder/recall will increase the receipt of immunizations and preventive services

Hypothesis 2: Telephone (autodialer) reminders will be more effective than mailed reminders

Hypothesis 3: The impact of reminders will be greatest for the most high-risk subgroups which have low baseline immunization rates.

Hypothesis 4: Mailed reminders will be more costly (and less effective) than telephone reminders.

Questions about this trial

What is this clinical trial studying?

A study testing Autodialer and Letters in people with Immunization Status and Well Child Care Visit, run by University of California, Los Angeles.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 20 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Fully Vaccinated (Tdap, Menactra and 3 Doses of HPV (if Female)) (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jan 2016.
