1. Discussion Abstract The implications of our findings will be related to hospital use and previous studies. Possible room for error or skew in the results due to limitation of resources will be addressed as well (ie. single hospital population). Results Data will be examined by using categorical data analysis, and judged on the basis of sensitivity and specificity. We hope that the results of this experiment reflect that specificity and sensitivity increase when the Neutrophil Lymphocyte Ratio data is combined with the Standard Early Warning Score data, rather than using just the Standard Early Warning Score data. We still need to determine what a positive test score is, or perhaps truncate ranges and do a more involved statistical analysis. True Positive False Positive TitleLuke Espina and Patrick Kettyle //Lets say that >5 is a positive test result. //lets say that < 5 is a negative test. True negative Sensitivity Conclusion False Negative Introduction The Neutrophil to Lymphocyte Ratio (NLR), a value representing the ratio of two different types of white blood cells in a patient, has been shown to be a good predictor of mortality given certain conditions. In this experiment we examine the ability of NLR to predict mortality in critically ill or injured patients, which has not been done before. When a hospital patient is admitted into the Intensive Care Unit (ICU), they are assessed to determine a diagnosis and their urgency of care. The accuracy of this initial assessment is vital for every patient so that there is a flow in triage that will allow all patients have attention in the right amount of time. A standard method used by doctors in the United Kingdom in triage is the Standard Warning Score (SEWS), assessing a patient’s temperature, systolic blood pressure, pulse rate, respiratory rate, oxygen saturation, and alertness, and determines a numeric score on a scale from Another test that has been researched and has been show to predict future mortality is the Neutrophil Lymphocyte Ratio. This ratio takes into account values of specific types of White Blood Cell counts and the ratio of these values is indicative of future mortality. Our experiment is to determine if these two independent tests can be combined to determine if a more accurate prediction of a patients future mortality can be made. Specificity SEWS Test SEWS + NLR Test Methods Patients that are included in this study are patients between the ages 20-80 that were transferred into the ICU within 2 days after admission, and/or patients that passed away within 30 days after admission. Exclusions from this study are patients who have any of the underlying conditions such as auto-immune disease, hematological disease, HIV and AIDS, or patients who are on an immunosuppressant, receiving chemotherapy, or cortical steroids.
