Assess the Acute Physiology and Chronic Health Evaluation IV (Apache IV) Score in Predicting Hospital Mortality Rate Among Critically ill Patients in Intensive Care Unit

Abstract

Background: Clinical evaluation is an important part of medical practice in which it predicts the prognosis of patients admitted to Intensive Care Units that can help in the definition of strategies, outlining plans for improving care, helping to prevent complications and achieving better quality indicators. Purpose: The purpose of the study is to assess the level of mortality among critically ill patients in association with their selected demographic variables. Materials and methods: Descriptive research design was conducted in the host institution of Saveetha Medical College and Hospitals with 60 samples who met the inclusion criteria were selected by convenience sampling technique.Demographic variables were collected by using multiple choice questionnaires. Acute physiology and chronic health evaluation IV score used for assessing the systolic and diastolic blood pressure, body temperature, heart rate, respiratory rate, glucose, blood urea nitrogen, serum sodium, creatinine, blood hematocrit, white blood cells, serum albumin and bilirubin, urine output during the first 24 h of ICU admission, pH, fraction of inspired oxygen, partial pressure of carbon dioxide, partial pressure of oxygen, and bicarbonate. Results:The study results concluded that, out of 60 samples ,that 52(86.7%) were under the estimated mortality between 0-25% and 8(13.3%) were under the estimated mortality rate between 26-50% and depicted that study findings shows patient with mechanical ventilator support, GCS had shown statistically significant association with APACHE IV score at p
