“…Standardization does not necessarily mean the uniform treatment of patients, but rather the adherence to general principles and the use of established classifications, medical ontologies, and concerted processes. The commonly used classification systems like the APACHE score for sepsis [14], the CHICAGO classification for esophageal motility [8], and the PARIS classification for gastrointestinal adenomas [13] all served as primers for the establishment of artificial neural networks in these fields. Likewise, the standardization of surgical processes, even at a very low level as proposed for cholecystectomy by Immenroth et al [15], is necessary for the computer-based interpretation of operative interventions and workflow recognition.…”
