About this study

Official title: Specific Respiratory Infections as Triggers of Acute Medical Events: Time Series Analysis Using LabBase and Hospital Episode Statistics

This study will investigate whether there is a population-level association between circulating respiratory viruses and NHS hospital admissions for acute vascular events using data from national infection surveillance and Hospital Episode Statistics.

Read the detailed description

We will conduct a time series study correlating anonymised population level data on all samples from NHS laboratories testing positive for six common respiratory viruses with admissions to NHS hospitals in England for a range of cardiac and vascular outcomes over the time period 01/01/2004 to 31/12/2014. This will involve generating Poisson regression models controlling for factors such as seasonal and long-term trends, environmental temperature and humidity.

This study is funded by an Academy of Medical Sciences Starter Grant for Clinical Lecturers.

Questions about this trial

What is this clinical trial studying?

An observational study of Influenza, Human and Respiratory Syncytial Virus Infections, run by University College, London at 1 site in United Kingdom.

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 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Acute myocardial infarction (time frame: 01/01/2004 to 31/12/2014). 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?

On the ClinicalTrials.gov record for NCT02984280, which also lists 1 linked publication.

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 4 May 2017.
