よくある質問

医師の診察で最も重要な英語フレーズは何ですか?

最も重要なのは症状を説明するフレーズです:「I have a sharp pain in...」(〜に鋭い痛みがあります)、「It started about... days ago」(約〜日前から始まりました)、「The pain is constant / comes and goes」(痛みは持続的/断続的です)。また理解を確認するフレーズも大切です:「Could you explain that again?」(もう一度説明していただけますか?)。症状と現在服用中の薬を英語でリストにして持参すると、医療従事者とのコミュニケーションが大幅に改善します。

医師に英語で痛みをどのように説明すればよいですか?

医師は標準的なシステムを使います。場所(「in my chest」—胸の中)、種類(「sharp」—鋭い、「dull」—鈍い、「throbbing」—脈打つ、「burning」—灼熱感)、1〜10の強度、タイミング(「constant」—持続的、「comes and goes」—断続的)、悪化・改善する要因を説明してください。「it radiates to my arm」(腕に放射する)や「it gets worse when I breathe in」(息を吸うと悪化する)などのフレーズは診断に重要な情報を提供します。

英国または米国の処方箋を理解するにはどのような語彙が必要ですか?

重要な用語:dosage(投与量)、frequency(頻度 — 「twice daily」は12時間ごと)、route(投与経路 — 「oral」経口、「topical」局所)、duration(期間 — 「for 7 days」7日間)。「PRN」は必要に応じて、「QD」または「OD」は1日1回を意味します。完全に理解できない指示があれば、必ず薬剤師に確認してください。

英語圏の医療従事者はスティグマを取り除く臨床的言語を使います:「I've been experiencing low mood」(気分が落ち込んでいます)、「I've been feeling overwhelmed」(圧倒されています)、「I've been struggling with anxiety」(不安と闘っています)。「I've not been feeling myself lately」(最近、気分が優れません)という穏やかな切り出し方も使えます。希望する場合は、心配事を書き留めて診察開始時に医師に渡すこともできます。

英語の健康保険用語について何を知っておくべきですか?

最も重要な用語:premium(月払い保険料)、deductible(保険が費用をカバーし始める前に自己負担する金額)、co-payment/co-pay(1回の受診ごとの定額負担)、out-of-pocket maximum(1年間の自己負担上限額)、in-network(保険会社と合意した料金を持つ医療機関)。英国では保険語彙よりも、GPの紹介、NHSの待機リスト、NHSと私的医療の違いを理解することが重要です。
