まとめ
国際標準化比率 (INR) の高い警戒値 (> 4. 5) は,臨床研究室では受け入れられないリスクをもたらす. この研究は,患者の安全のために改善された実験室の制御措置を必要とする,頻繁な発生と重大な結果を強調しています.
科学分野:
- 臨床研究室科学
- 医療診断
- 患者の安全
背景:
- 国際標準化比率 (INR) は,ビタミンK抗体治療のモニタリングに不可欠です.
- 最適な患者ケアのためには,検査室でのINRアラート値の効率的な管理が不可欠です.
- INRアラート値に関連したリスクレベルを評価することは,臨床研究所の品質の改善に不可欠です.
研究 の 目的:
- 国際標準化比率 (INR) 警報値のリスクレベルを第三次医療病院で評価する.
- 観測されたINR警告値のリスクを,確立された基準値と比較する.
- INRアラート値に寄与する根本的な原因と故障モードを特定する.
主な方法:
- 12ヶ月の期間 (2023年9月〜2024年8月) にわたるINR値の42,799個のプラズマサンプルを分析した.
- リスク評価マトリクスを使用して,INR値 > 4.5 のリスクレベルを評価する.
- INR 警報値が発生する日当たりの確率の計算
- 臨床実験室内のサンプル輸送とドキュメンテーションの評価
主要な成果:
- 42799個のサンプルのうち347個 (0. 81%) がINR警戒値 (> 4. 5) を示した.
- INRの警戒値>4. 5は,高頻度 (毎日0. 95) と重大な結果のために,受け入れられないリスクレベルとして分類されました.
- 潜在的故障モードには,不完全な通信文書と重要な再サンプリングの遅延 (症例の30%で6時間) が含まれていた.
結論:
- INRの警戒値>4. 5は,臨床研究室の設定では,重要で受け入れられないリスクを表します.
