Previous research

This page provides information about the previous research studies within West Midlands Ambulance Service.

PARAMEDICPARAMEDIC

This study tested a mechanical chest compressor device against the manual chest compressions given by ambulance staff. The study found no patient benefit to routinely using these devices, although they may still be used in certain circumstances. It provided reassurance that ambulance staff already provide high quality CPR. Results are available here.

PARAMEDIC2PARAMEDIC 2 Logo for documents

PARAMEDIC2 tested the long-term patient outcomes of a medicine called adrenaline, which has been commonly used by ambulance services for many years. Patients with cardiac arrest were slightly more likely to survive if given adrenaline, but the drug doubled the risk of brain injury. The study showed that adrenaline is much less important as a treatment than bystanders recognising cardiac arrest, as well as early CPR and defibrillation. Results are here.

VANPicture10

Understanding variation in rates of ambulance service non-conveyance (VAN) of patients to an emergency department showed that some ambulance services are better than others at caring for patients without transporting them to an Emergency Department, and suggested ways that trusts can improve the numbers of patients cared for in their own homes, either after telephone advice (“hear and treat”) or a face-to-face visit (“see and treat”).

CLOSEDPicture7

This study looked at the impact of closing or downgrading Emergency Departments in England. The researchers found that there was no evidence of either positive or negative impacts to patients, although closures did increase the overall number of incidents attended by ambulance services.

RIGHT-2

This study tested the use of a simple skin patch to improve functional outcomes for stroke patients. Ultimately, RIGHT-2 showed that the patch was neither helpful nor harmful, but it did prove that paramedics are able to research new treatments even in very challenging circumstances.

ATLANTICATLANTIC on the left

Our first medicine trial that WMAS took part in was a study looking at a drug to help heart attack patients. It showed that ambulance crews could safely administer ticagrelor to these patients, but that this was no better for their outcomes than giving it in hospital.  To find out more about the study click here.
