Long-term Evaluation of Patients Treated by an Emergency Medical Helicopter
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.
