Early warning scoring systems are used by medical staff to determine the risk of a patient experiencing severe health
deterioration. They use physiological variables such as blood pressure, heart rate, respiratory rate, core body
temperature and blood oxygen saturation for calculating a score which determines a patient’s risk of health collapse.
Limited research exists on the relationship that might exist between these variables. This study presents the results
from a correlation and a regression analysis. Studying the correlations between vital signs will allow for a better
understanding of early warning scoring systems because it will explore the possibility of inflated scores that result
from the inclusion of vital signs in their calculation that have high correlation.
