まとめ
eConsult (eConsult) へのトライアジング・レファレンス (TReC) は,カナダの3つの病院で成功裏に拡大され,スペシャリストの待ち時間を大幅に短縮し,ケアへのアクセスを改善しました. この革新的なシステムは,高い提供者および患者の満足度を示し,医療の課題に対する費用対効果の高いソリューションを提供しています.
科学分野:
- 医療サービス 研究 医療サービス
- デジタルヘルスの実施について
- 医療へのアクセスと公平性
背景:
- カナダの保健医療は,専門医療へのアクセスで重大な課題に直面しており,その結果,長期の待ち時間と非最適の患者のアウトカムがもたらされています.
- オタワ病院は,既存の健康情報システム (HIS) と紹介ワークフローに専門家の助言を統合するために,eConsult (TReC) へのトライアージング・リファレルを開発しました.
- RE-AIMの枠組みは,複数の医療環境におけるTReCの実施と影響を体系的に評価するために選択されました.
研究 の 目的:
- カナダの3大病院におけるeConsult (eConsult) へのトライアージング・リファール (TReC) システムの実装,有効性,およびスケーラビリティの評価.
- TReCが専門医療へのアクセス,対応時間,コスト,ユーザーへの受け入れ能力に与える影響を評価する.
- TReCが専門家のコンサルティングに適時かつ公平なアクセスを改善する可能性を決定する.
主な方法:
- RE-AIMの枠組みが評価の指針となり,リーチ,有効性,採用,実施,維持を評価した.
- オタワ病院 (TOH),女子大学病院 (WCH),オンタリオ東部児童病院 (CHEO) の患者と医療従事者に管理された行政記録と調査を通じてデータを収集した.
- 重要な指標には,専門家の参加数,eConsultの量,平均応答時間,ケースあたりのコスト,およびアドバイスの実行可能性とアクセス改善の認識に関するユーザー満足度評価が含まれています.
主要な成果:
- TReCは,TOHで160,WCHで22,CHEOで26の重要な専門家の参加と,TOHで1万件以上のeConsultの大量の実施を成功裏に実施しました.
- eConsultsの平均応答時間は2〜8日間で,オンタリオ州の専門家の個人訪問の23週間の平均よりも大幅に短かった.
- このシステムは高い受け入れ率を示しており,医療従事者の84~91%がアドバイスが実行可能であると認め,患者の70%が懸念事項が解決されたと感じ,専門家の91%が改善されたアクセス感を示しており,そのすべては1症例あたり37 CADの低コストで実現している.
結論:
- トライアージング・レファレンス・トゥ・eコンサルト (TReC) システムは,複数の病院で成功裏に拡大され,専門医のケアへのタイムリーなアクセスを大幅に改善しました.
- 紹介する提供者,患者,および専門家の間で高いレベルのユーザー受け入れは,TReCの有効性とより広範な採用の可能性を強調しています.
- この発見は,オンタリオ全域の医療へのアクセスと公平性を改善する戦略としてTReCの拡大を支持し,同様の課題に直面している他の地域にも可能性が高い.

An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
