  1. Automation coding system on mortality in Japan Moriyo Kimura, MD MPH ICD office Ministry of Health, Labour and Welfare, Japan

  2. ACSEL Automated Coding of diagnostic expressions and SELection of underlying cause of death

  3. Characteristics of ACSEL • ACSEL’s difficult, complicated Japanese processing ability. • Neoplasm’s automation processing in Phase II.

  4. Data editing Data editing ＰＨＡＳＥⅠ ＰＨＡＳＥⅠ ＰＨＡＳＥⅡ ＰＨＡＳＥⅡ Data sheet MHLW Online Data handling OCR Dictionary Tables Municipalities Health Centres registration Manual data handling Manual data handling

  5. Data editing and phase I

  6. Data editing Difficult, Nasty Japanese Data editing ＰＨＡＳＥⅠ ＰＨＡＳＥⅡ ○　Topographical errors ○　Space, hyphenation ○　Capitalization ○　Kanji, Hiragana, Katakana adjustment

  7. Phase I Data editing Element file Element analysis ＰＨＡＳＥⅠ Various file ＰＨＡＳＥⅡ Element editing Element sorting Dictionary file Matching Condition file Confirmation ICD coding

  8. PhaseⅡ Data editing ＰＨＡＳＥⅠ Table C TUD ＰＨＡＳＥⅡ Table D Modification rules neoplasms Table E Trivial condition Japanese rules Table F Domestic code removal UCD

  9. Neoplasms Data editing 1. Systematic automation coding adopting ICD-O Example 1. a. Stomach cancer b. pancreatic cancer　　　　　→ C26.8 Example 2. a. small cell lung cancer b. HCC → C97 2. Overcoming Linguistic complicity of Japanese Example. 転移肺癌　→　lung metastasis 肺癌転移　→　metastaticlung cancer ＰＨＡＳＥⅠ ＰＨＡＳＥⅡ

  10. Coding Accuracy Total manual coding AC total Agreement 990,736 *73,683 917,049 869,362 (100%) (7.4%) (92.6%) (94.8%) 2002 data *The data for manual coding was mainly the external cause of death
