Seven years ago, while assistant director of emergency medicine at NTUH, Chang Hang pushed for the hospital to build intensive care rooms for the emergency room. The ER was running out of space and there were emergency patients who could not be admitted to the intensive care units. The hospital, however, would not support him.
張珩曾是台大急診部副主任，七年前在台大推動成立急診加護病房，容納情況危急、卻又住不進加護病房的急診病患，但是在院內得不到支持。
