Examination of the Standardized Use of the Pulmonary Embolism SOP in the Clinical Routine of the Emergency Department.

Usage of a guideline-compliant SOP in each chest pain unit (CPU) is instrumental in establishing the diagnosis of a pulmonary embolism without time delay. With the integration of this SOP as a "clinical decision tool" (CDT) into the electronic database of the CPU, the standardized application of the pulmonary embolism SOP in the clinical routine of the CPU will be tested using a retro- and prospective approach.
