RESUMO
BACKGROUND AND OBJECTIVES: It takes considerable time and effort to make an operation record for the chronic otitis media. Also there are risks of incorrectness or omission of data. We developed an automatic operation recording system in order to reduce the burden of the resident keeping the record and to give completeness to the operation data. SUBJECTS AND METHOD: The model-view-controller (MVC) pattern isolates the domain logic (controller) from the user interface (data model-view), permitting independent development. We used the MVC pattern to design the program it since it matched with the feature of the operation recording system. RESULTS: We implemented this system using the Python programming language, which is composed of 98 fields and 4 different types of widgets linked to those fields. The outputs of the 4 views can be easily copied and pasted to the word processor and the electronic medical recorder. In the pilot test, this system reduced significant amount of time and effort needed for operation recording. CONCLUSION: The automatic operation recording system reduces the resident's works and the operation data loss. Furthermore, it could be applied to other types of operation records.
