- 臨床データマイニング
背景:
- 病院での圧力傷害 (PI) は,医療の質の重要な指標です.
- 病院で発症するPIの流行は増加傾向にあります.
- PIの効果的な予測は,適切な介入に不可欠です.
研究 の 目的:
- 病院で受けた圧力傷害の予測指標を特定する.
- 電子医療記録システムからこれらの指標を自動的に抽出するシステムを開発する.
主な方法:
- 専門家インタビュー,文献レビュー,調査を含む,修正されたデルフィの方法が指標開発に使用されました.
- 特徴の選択は,SQLを使用してヘルスケア情報システム (HIS) からインジケーターを抽出することでした.
- ランダムフォレスト技術が指標の選択に用いられました.
主要な成果:
- 3つのカテゴリーと14の指標を備えた予測指標システムが確立されました.
- すべての指標で高い専門家のコンセンサスが達成された (合意率は83.30%~100.00%).
- 自動予測モデルは手動抽出と自動抽出との良好な一致性 (95.26%) を示した (コーエン κ 0.64-1.00).
結論:
- 開発された予測インジケーターシステムは,HIS内の圧迫傷害の自動予測に適しています.
