まとめ
長期にわたる静脈注射による抗菌薬の使用は 重要な臨床廃棄物と炭素排出を生成します 抗生物質管理 (AMS) を最適化することで,環境への影響を軽減し,抗生物質耐性に対抗することができます.
科学分野:
- 環境科学
- 感染症
- 公衆衛生
背景:
- 長期にわたる静脈注射 (IV) 抗菌薬の投与は,患者の安全を脅かし,環境汚染に貢献します.
- 抗生物質管理 (AMS) プログラムは,抗生物質の使用を最適化し,耐性を軽減するために不可欠です.
- 医療の環境への影響,特に抗菌薬の処方については 徹底的な評価が必要である.
研究 の 目的:
- 長時間投与された抗菌薬の環境への影響を定量化する.
- 廃棄物と排出量を削減するためのAMSの改善の機会を特定する.
- 病院でのIV抗菌薬の使用に関連する炭素フットプリントを評価する.
主な方法:
- アイルランド・ダブリンにある高等病院 (2023年1月~2024年12月) の AMS 病棟全体のデータを分析したレトロスペクティブ・クロスセクション研究.
- データには,IV抗菌剤の処方,AMSの推奨 (中止またはIVから口服への切り替え - IVOS),および処方者の承認が含まれていた.
- 出版された文献に基づいたライフサイクル評価で,IV抗菌剤の使用による炭素フットプリントが推定されました.
主要な成果:
- 1929年に審査された抗菌薬の処方箋の58%はIVであった.
- 229件のIV処方箋に対するAMSの推奨の受け入れにより,106. 5kgの臨床廃棄物と261.2kgのCO2eが削減されました.
- 残りの206の長時間IV処方薬は98. 8kgの廃棄物と245. 8kgのCO2eを生成し,ピペラシリンタゾバクタムは主な原因である.
結論:
- 長期にわたる注射抗菌剤の使用は 環境に大量の廃棄物と炭素排出を 引き起こします
- AMSの実践に持続可能性の目標を組み込むことで 抗菌剤耐性や気候変動の両方に対処できます
- 医療の環境負担を減らすために 抗菌剤の処方量を最適化することが不可欠です
