We aimed to evaluate the role of National early warning score in detecting and decreasing cardiorespiratory arrest amongst patients with acute coronary syndrome. Materials and Methods: a retrospective cohort study was undertaken on 60 patients with Acute Coronary Syndrome (ACS) at Coronary Care Unit (CCU). Data collection occurred over 3 phases. Phase I (Pre-NEWS data collection); physiological parameters were extracted retrospectively between 1 May 2019 and 30 July 2019 using Electronic Health Intelligence System (HIS). Phase II: one-month (1st -30th August, 2019); introduction and training of critical care nurses and doctors in CCU about NEWS. Phase III: Post NEWS data collection; physiological parameters were collected directly from the patients with ACS between 1 September 2019 and 30 November 2019. Results: the mean of NEWS, was 1.42 and 5.52 for the Post NEWS and Pre NEWS groups respectively with a statistically significant difference between them (p<0.001). It was noticed that a significant decrease in cardiorespiratory arrest and death in Post NEWS group (36.6%, 20%) versus Pre NEWS group (66.7%, 56.7%) respectively. Conclusion: The NEWS was significantly effective in decreasing occurrence of cardiorespiratory arrest and death. So, the NEWS is a useful tool to identify patients with ACS at greatest risk of cardiorespiratory arrest. Therefore, applying the NEWS as a part of routine nursing assessment for all patients with ACS is highly recommended. http://pubs.sciepub.com/ajnr/8/3/11/ajnr-8-3-11.pdf warning signs cardiorespiratory arrest early warning score and acute coronary syndrome
