TI  - [Calibration of clinical databanks with "virtual patients"].
PG  - 35-41
AB  - The scientific value of multicenter studies is still questionable, as there are 
      no methods available that allow to determine whether in fact identical items are 
      recorded in the same way in different centers. Subjective classifications (for 
      example according to the New York Heart Association (NYHA)), definitions of 
      items, documentation habits and procedures may not be comparable in different 
      hospitals. For that reason the concept of a "virtual patient" for calibration of 
      database systems was developed as a new methodological approach. The "virtual 
      patients" describes a computer program that includes and uses multimedia-tools to 
      represent an exactly defined patient. A sound card enables a patient to talk and 
      to represent intracardial and intrapulmonary sounds. Additional information 
      including echocardiographic sequences, perioperative video sequences, x-ray 
      analysis, angiograms, etc. is represented in the program. Thus during the 
      perioperative course of a patient the complete relevant pre-, intra- and 
      postoperative information regarding the patient is provided. Any physician 
      participating in a multicenter study is asked to record the data of this virtual 
      patient and to store it in a database system using the sheets applied in a 
      multicenter study. As the patient is exactly defined (virtual patient) incorrect 
      classifications and incomplete recordings, etc. can easily be detected and 
      discussed. The virtual patient is a tool that allows calibration of database 
      systems by direct comparison of the documentation technique between different 
      physicians and different hospitals participating in multicenter studies. It is 
      thus a multimedia-instrument to support standardization and quality assurance of 
      database systems.
