Outline of Final Research Achievements

The aim of this study was to establish and validate risk models of mortality and morbidity associated with 12 major pediatric surgical procedures using the National Clinical Database-Pediatric (NCD-P) data. Overall, 10 and 21 variables were identified for mortality and morbidity, respectively. C-indices of mortality were 0.940 and 0.924 in the development and validation datasets, respectively. C-indices of morbidity were 0.832 and 0.830 in the development and validation datasets, respectively. Based on the NCD-P data, we developed satisfactory risk models for mortality and morbidity prediction in major pediatric surgeries. Based on the results of this study, we have determined the specifications of a risk calculator for the 12 most difficult pediatric surgery procedures in Japan.Based on this specification, we are developing a web-based system to visualize the risk of death and complications by inputting case information into the system.

Academic Significance and Societal Importance of the Research Achievements

施設や地域に,医療の質指標の数値を,全国的な数値とともに報告することで,施設や地域ごとに自らの治療方針を見直し,方針を議論する機会などを提供することを通して医療の質の向上が期待されている。手術リスクを調整した術後の死亡率・罹患率の推定モデルを構築すれば,医療の質を示す指標のひとつとなりうる。本研究では小児外科の12の高難度術式について死亡と主要な合併症のリスクモデルを構築した。それに基づいて,症例の情報を入力することで,死亡と合併症の発生リスクを可視化することが可能となる上のリスクカリキュレータシステムをウェブ上に構築する仕様を決定し実装を進め,小児外科領域の医療の質を高めることに寄与した。
