この研究はハイインパクトの可能性があります。 OEのAI駆動型ハイインパクト指標は、論文が掲載されたジャーナルと論文自体の科学的内容の両方からのシグナルを統合することで、論文が持つ可能性の高い影響力を推定します。 最先端の自然言語処理を用いて開発されたOEハイインパクトモデルは、ジャーナルのインパクトファクターのみよりも、研究の将来の引用実績をより正確に予測します。 これにより、臨床的に意義のある研究をより早く認識することが可能になり、読者は将来の診療を形成する可能性が最も高い論文に集中することができます。

161 patients presenting to the emergency department with a hip fracture were randomized to administration of a femoral nerve block in the ED followed by a fascia iliac block within 24 hours, or to standard intravenous and oral analgesia during the perioperative stay. Patients were followed up for preoperative and postoperative pain, opioid consumption, functional ability, and the incidence of opioid-related adverse events up to 3 days postoperatively. Results demonstrated that the peripheral nerve block regimen was associated with significantly lower pain scores and analgesic requirement preoperatively and after 3 days postoperatively, as well as a longer distance walked over a 2 minute period on the third postoperative day when compared to standard oral and IV analgesics.
