Outline of Research at the Start |
循環器救急疾患のひとつである急性大動脈解離の入院に気温・大気汚染物質等の自然環境が与える影響について、日本循環器学会の循環器疾患診療実態調査データベース(日本全国の循環器専門施設の入院データ)と気象庁の気象データ、国立環境研究所の環境数値データベースを用い検討する。

Outline of Final Research Achievements |
Using the JROAD-DPC database, we presented a conference and wrote a paper on the impact of weekend hospitalization on in-hospital mortality in acute aortic dissection (AAD).The total 33,706 patients for AAD hospitalized higher on weekdays compared to weekends, with an in-hospital mortality rate of 21.9%. Patients admitted on Sundays and holidays showed a significant increase in in-hospital mortality compared to weekdays. In particular, stratified analysis of the Stanford classification by site of dissection showed that only type A patients admitted on Sundays and holidays had a significant increase in in-hospital mortality. In conclusion, our results suggest that the risk of in-hospital mortality may be higher for AAD Stanford type A patients admitted on Sundays and holidays.

Academic Significance and Societal Importance of the Research Achievements |
急性大動脈解離の疫学研究が限られている中、全国の循環器専門施設データであるJROAD-DPCデータベースを用いて国内の急性大動脈解離の入院について網羅的に検討を行うことが可能となった。週末に入院をする急性大動脈解離、特に緊急手術など医療資源がより必要となるスタンフォードA型の急性大動脈解離では院内死亡リスクが高いことが示唆され、今後は長期予後を含めた検討や、死亡リスクが高い理由の詳細な検討が必要である。
