Effect of Pre-existing Medical Conditions on In-Hospital Mortality: Analysis of 20,257 Trauma Patients in Japan

Abstract

The existence of certain PMCs or of 2 or more PMCs increases in-hospital mortality from injury. This effect is particularly conspicuous in middle-aged patients and people with minor injuries, but was not found to be a problem among elderly people. The increased mortality from injury in elderly people in Japan is therefore not affected by the existence of PMCs.
