Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A cardiac arrest is often preceeded by a varying period of physiological deterioration which if acted upon may prevent the cardiac arrest. We aim to review patients presenting to the ambulance service with cardiac arrest so see if they had contacted the ambulance service in the preceeding 48 hrs to understand if warning symptoms were missed or not acted upon appropriately.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The UK ambulance services are called to attend 60,000 out-of-hospital cardiac arrests (OHCA) each year. Hospital studies have shown that many patients who suffer an in-hospital cardiac arrest (IHCA) have been deteriorating for the preceeding 48 hrs and suggest that many IHCA are potentially avoidable if this deterioration is identified and actued on promptly. No similar study has been performed to see if patients suffering OHCA have also presented with warning signs in the preceeding 48 hrs that were overlooked.

Intervention Type DIAGNOSTIC_TEST

Patients seen by ambulance crews within the preceeding 48 hrs of their cardiac arrest will have a NEWS2 score performed to assess the level of physiological deterioration at the time of thei intial assessment.
