11.1 🎓 醫學生版
給醫學系 M3-M6:理解 health disparities 是 21 世紀醫學核心議題。配 Harrison 22E Ch 11 原文 對照閱讀。
11.1.0.1 📌 一頁重點整理 (TL;DR)
- Health disparities = 不同族群之間 health outcome 的差異,不是隨機而是源於 social determinants of health (SDOH)
- IOM 2003 「Unequal Treatment」 是 modern disparities awareness 起點
- 美國數據:Black Americans CV mortality 高、maternal mortality 3-4× white
- Implicit bias + structural racism + socioeconomic factors 共同作用
- Social Determinants of Health (SDOH):教育、收入、住房、食物安全、neighborhood、healthcare access
- Healthcare disparities ≠ healthcare access alone:即使 access 一樣,outcome 仍差
- Implicit bias training + diverse workforce + policy reform 是 multipronged 對策
- 📍 台灣 disparities:城鄉差距、族群差距(原住民健康)、健保 coverage 但 utilization 差距
🎯 三件事必須記住 1. Disparities 不是純基因,是 social determinants 主導 2. Implicit bias 是 universal,不是「壞人」才有 3. Address SDOH 是長期解法
11.1.0.2 🧠 核心概念
11.1.0.2.1 Health Disparities 定義
WHO: differences in health outcomes between groups that are systematic, plausibly avoidable, and unfair.
要件: - Systematic(不是隨機) - Plausibly avoidable(不是不可改) - Unfair(與 ethics 相關)
11.1.0.2.2 IOM 2003 「Unequal Treatment」 Report
主要 findings: - Racial/ethnic disparities exist across all clinical settings - 即使 controlled for insurance、income、disease severity - → suggests healthcare system itself contributes
11.1.0.2.3 美國 Disparities Data(22E 引用)
11.1.0.2.3.1 CV 健康
- Black Americans CV mortality 30-40% higher than White
- Hypertension prevalence 高 + 控制率低
- Stroke incidence 2× white
11.1.0.2.3.2 Maternal Mortality
- Black women maternal mortality 3-4× white
- Native American 也高
- 原因 multifactorial(implicit bias、access、SDOH)
11.1.0.2.5 Implicit Bias
- Unconscious associations 影響 perception + behavior
- Implicit Association Test (IAT) 是評估工具
- 醫師 implicit bias 影響:pain management、specialist referral、surgical recommendation
- Universal:所有人都有,包括 minority providers
- 解法:awareness training、structured decision-making、diverse team
11.1.0.2.6 Structural Racism
- 不是個人偏見,是 system-level
- 例:redlining 歷史 → 現今 neighborhood disparities → health
- Healthcare system structure:academic vs safety-net hospitals
- Insurance system:public vs private
11.1.0.2.7 Disparities Are Not Just Access
22E 強調: - 即使有 insurance、access,outcome 仍差 - → healthcare quality 也有 disparities - → bias、communication、cultural mismatch
11.1.0.2.8 Solutions(multipronged)
11.1.0.2.8.1 Individual Provider Level
- Implicit bias awareness
- Cultural humility(不只 cultural competence)
- Structured clinical decision-making(reduce bias)
- Active language access(interpreters)
11.1.0.3 🔑 Mnemonic
11.1.0.4 💡 Case 思考
35 歲 Black F G2P1 來 OB 產檢,第一胎 placental abruption。這次妊娠 36 wk + persistent headache + BP 140/90 + epigastric pain。
SDOH + Disparities 思考: - Black F maternal mortality 3-4× higher - Severe preeclampsia / HELLP 不能漏 - Implicit bias risk:dismiss as “anxiety” - 醫師應 take symptoms seriously、aggressively work up - BP、UA、CBC、LFT、coagulation panel、fetal monitoring - 必要時 immediate delivery - → Don’t dismiss; act on objective data

11.1.0.2.4 Social Determinants of Health (SDOH)
WHO + Healthy People 2030 framework:
→ 估計 80% health outcome 由 SDOH + behavior 決定,只 20% 由 healthcare system
