Abstract
Background. Early warning scores using physiological measurements may help identify ward patients who are, or who may become, critically ill. We studied the value of abnormal physiology scores to identify high‐risk hospital patients. Methods. On a single day we recorded the following data from 433 adult non‐obstetric inpatients: respiratory rate, heart rate, systolic pressure, temperature, oxygen saturation, level of consciousness, urine output for catheterized patients, age and inspired oxygen. We also noted the care required and given. Results. Twenty‐six patients (6%) died within 30 days. They were significantly older than survivors (PPPConclusions. Simple physiological observations identify high‐risk hospital inpatients. Those who die are often inpatients for days or weeks before death, allowing time for clinicians to intervene and potentially change outcome. Access to critical care beds could decrease mortality.
