BACKGROUND: There is scant research concerning the prediction of imminent death, and current studies simply list events "that have already occurred" around 48 h of the death. We sought to determine what events herald the onset of dying process using the length of time from "any change" to death. METHODS: This is a prospective observational study with chart audit. Inclusion criteria were terminal cancer patients who passed away in a palliative care unit. The analysis was limited to 181 patients who had medical records for their final week. Commonly observed events in the terminally ill were determined and their significant changes were defined beforehand. We selected the statistically significant changes by multiple logistic regression analysis and evaluated their predictive values for "death within 48 h." RESULTS: The median age was 67 years and there were 103 male patients. After adjusting for age, sex, primary cancer site, metastatic site, and cancer treatment, multiple logistic regression analyses for association between the events and "death within 48 h" revealed some significant changes: confused mental state, decreased blood pressure, increased pulse pressure, low oxygen saturation, death rattle, and decreased conscious level. The events that had higher predictability for death within 48 h were decreased blood pressure and low oxygen saturation, and the positive and negative predictive values of their combination were 95.0 and 81.4%, respectively. CONCLUSION: The most reliable events to predict impending death were decreased blood pressure and low oxygen saturation.
