Impact of Rotavirus Vaccination on Hospitalisations for Rotavirus Gastroenteritis in Children Aged <5 Years in Australia

June 6, 2017 updated by: GlaxoSmithKline

A Study on the Impact of Rotavirus Vaccination on Hospitalisations for Rotavirus Gastroenteritis in Children Aged <5 Years in Australia

This study aims to monitor the incidence rates and duration of hospitalisations for rotavirus gastroenteritis (RV GE) and all cause GE, compared to bronchiolitis from 1998 to 2009, in children < 5 years of age after the introduction of Rotarix in 2006 by year, both inside and outside rotavirus season in Australia. It further aims to compare the two dose regimen of Rotarix with the three dose regimen of RotaTeq from 2007 to 2009.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 5 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Australian children aged < 5 years who have been vaccinated with RotaTeq (in Queensland) and Rotarix (in New South Wales) from 2007 to 2009 as well as all children aged < 5 years hospitalised for all-cause gastroenteritis, rotavirus gastroenteritis or bronchiolitis, before and after introduction of Rotarix vaccination in New South Wales, Australian Capital Territory, Tasmania and Northern Territory, from 1998 to 2009.

Description

Inclusion Criteria:

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Study Group
Australian children aged < 5 years who have been vaccinated with RotaTeq or Rotarix from 2007 to 2009 as well as all children aged < 5 years hospitalised for all-cause gastroenteritis, rotavirus gastroenteritis or bronchiolitis.
Other: Database analysis
Existing computerised administrative databases from the Australian Institute of Health and Welfare (AIHW) will be reviewed to retrieve data on all-cause gastroenteritis/ rotavirus enteritis and bronchiolitis hospitalisations of children <5 years in all the states using Rotarix from 1998 to 2009. Data from Australian Childhood Immunisation Register (ACIR) post introduction of rotavirus vaccines in the National Immunisation Program (2007 to 2009) will also be used.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.

The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
