レジデントノート

米国にて内科修行中。何ができるか模索している過程を記録していく

救外より入院依頼を受けてから指示出し,ノート記載を終了するまでの経時的行動

 

ここでの主なコンセプトは入院対応におけるタイムマネージメントである

救急から入院依頼が引っ切り無しに来る場合、とても各所を行ったり来たりしている余裕はない

どこで時間をロスするかを考え、それを減らすための対策を行う

 

例えば 

・入院場所が違う

本当はICUが必要だった、そもそも病院のキャパシティーで対応できない場合、転棟・転送になるともう限りなく時間が消費されてしまう

・入院した後に追加の画像検査などが必要であったと気づく

救外で行えればスムーズであるが、一旦入院してしまうと対応が後手後手になってしまう

・問診の抜け

患者とカルテとの間を行ったり来たりする時間は大きなロスとなる

・患者が来院当日の薬を内服したかの確認

ワーファリンやlong-acting insulinなど入院後いつから開始するかが異なってくるため必要な情報だが、個人的にはこの確認のし忘れを頻回にしでかし、患者のもとに戻らなければならない事が多々ある

 

他にも大小無数にあるが、それらを如何に少なくできるか奮闘している試行過程を記す

救急外来でのバイタルサインの異常、検査値異常は基本的にすべてフォーマット右端のプロブレムリストに追加、検査値異常が新たなものか、慢性的なものか過去の情報より確認(腎機能, 貧血, 血小板数, Na, 肝酵素,・・・)、新たなものである場合でそのアセスメントのために追加検査が必要な時はPlanに追加

④過去の心エコーを確認(多量の輸液投与が予想されるとき)、右下の過去の診療録欄に心機能を記載(拡張能障害にも注意)
