癌症自1982年起已蟬聯國人十大死因第一位多年，因此衛生福利部至1979年起以行政命令要求50床以上醫院申報癌症登記資料至國民健康署，以建立本土性的癌症登記資料庫，做為癌症篩檢與診療之政策推動與監測參考，因此癌症登記資料正確率實為重要，癌症登記審查機制為確保癌症登記資料品質之必要工作，為縮短癌症登記審查文書作業流程、減少人工輸入錯誤及配合全球綠色資訊無紙化趨勢，建置癌症登記審查系統，並利用執行過程之經驗持續優化並整合相關作業系統，最後，成功將癌症登記審查作業時間從平均508分鐘/季降低至171分鐘/季，也落實作業流程無紙化的目標，透過此專案改善後所節省的時間，癌症登記師能更專注於癌症登記病歷摘錄及數據分析，提供完整且正確的癌症登記大數據資料，以利癌症相關研究及公共衛生政策之實施，增進國人健康福祉。

In Taiwan, cancer has been ranked first among the top ten causes of death among for many years since 1982. Therefore, the Ministry of Health and Welfare issued an executive order in 1979 to require hospitals with more than 50 beds to report cancer registration data to the Bureau of Health Promotion, Department of Health, Executive Yuan to establish a local cancer registration database. As a policy promotion and monitoring reference for cancer screening and diagnosis and treatment, the accuracy of cancer registration data is really important. The cancer registration review mechanism is a necessary work to ensure the quality of cancer registration data. However, for shortening the process of cancer registration review paperwork and avoid typing mistakes and in line with the global trend of green information paperless, built a cancer registration review system, and continued to optimize and integrate related operating systems using the experience of the implementtation process. Finally, the cancer registration review operation time was successfully reduced from an average of 508 minutes per quarter to 171 minutes per quarter, the goal of paperless operation process is also implemented. Through the time saved by the improvement of this project, cancer registrars can focus more on the extraction and data analysis of cancer registration medical records, and provide complete and accurate cancer registration big data. To facilitate the implementation of cancer-related research and public health policies, and to improve the health and well-being of the people.
