Purpose:To replace the paper records, we designed an electronic records function for plan checked meeting in our in‐house developed radiotherapy information management system(RTIMS).Methods:Since 2007, the RTIMS has been developed on a database and web service of Apache+PHP+MySQL, and almost all computers and smartphones could access the RTIMS through IE browser, to input, search, count, and print the data. In 2012, we also established an radiation therapy case conference multi‐media system(RTCCMMS) based on Windows Remote Desktop feature. Since 2013, we have carried out the treatment plan checked meeting of the physics division in every afternoon for about half an hour. In 2014, we designed an electronic records function, which includes a meeting information record and a checked plan record. And the meeting record includes the following items: meeting date, name, place, length, status, attendee, content, etc. The plan record includes the followings: meeting date, meeting name, patient ID, gender, age, patient name, course, plan, purpose, position, technique, CTsim type, plan type, primary doctor, other doctor, primary physicist, other physicist, difficulty, quality, score, opinion, status, note, etc.Results:In the past year, the electronic meeting records function has been successfully developed and implemented in the division, and it could be accessed from an smartphone. Almost all items have the corresponding pull‐down menu selection, and each option would try to intelligently inherit default value from the former record or other form. According to the items, we could do big data mining to the input data. It also has both Chinese and English two versions.Conclusion:It was demonstrated to be user‐friendly and was proven to significantly improve the clinical efficiency and quality of treatment plan. Since the RTIMS is an in‐house developed system, more functions can be added or modified to further enhance its potentials in research and clinical practice.Project supported by the National Natural Science Foundation of China (Grant No.81101694).
