About this study

In May 2010 the first danish physician-staffed Helicopter Emergency Medical Service (PS-HEMS) was implemented in Region Zealand and the Capital Region (excluding Bornholm) of Denmark.

In relation to the introduction of PS-HEMS, a team of collaborators lead by Rasmus Hesselfeldt, conducted an observational study to investigate the possible effects on time to definitive care, secondary transfers and 30-day mortality in a "before" and "after" design.

Results showed reduced time from first dispatch to arrival at the trauma centre from 218 min to 90 min. Secondary transfers to the trauma centre dropped from 50 % to 34 % and 30-day mortality significantly reduced from 29 % to 14 % in the year after implementation.

The present study is an observational cohort study with long-term follow-up of the same trauma population as mentioned above. Patients were followed until may 1st, 2014.

Primary outcome is early retirement and secondary outcomes are quality of life and mortality.

The investigators hypothesize that a greater proportion of trauma patients in the "after" period will remain in occupation after approx. 3 to 4.5 years compared with trauma patients treated in the "before" period.

What participants receive

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

Questions about this trial

What is this clinical trial studying?

An observational study of Wounds and Injuries, run by Copenhagen University Hospital, Rigshospitalet at 1 site in Denmark.

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 2 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 28 Oct 2015. 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 Denmark. 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?

Labor market attachment (time frame: 3 - 4.5 years after trauma). 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 NCT02175862, which also lists 7 linked publications.

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 28 Oct 2015.
