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)
11.1.0.2.3.3 Cancer
  • Black men prostate CA mortality 2× white
  • Triple-negative breast CA 較常見於 Black women
11.1.0.2.3.4 COVID-19
  • Black、Hispanic、Native American hospitalization、mortality 顯著高
  • → exposed structural inequities
11.1.0.2.4 Social Determinants of Health (SDOH)

WHO + Healthy People 2030 framework:

  1. Economic stability:收入、employment、food security、housing
  2. Education access + quality
  3. Healthcare access + quality
  4. Neighborhood + built environment:safe housing、transportation、pollution
  5. Social + community context:social cohesion、discrimination

→ 估計 80% health outcome 由 SDOH + behavior 決定,只 20% 由 healthcare system

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)
11.1.0.2.8.2 Healthcare System Level
  • Diverse workforce
  • Quality metrics by race/ethnicity
  • Address access barriers
  • Patient navigation programs
  • Trauma-informed care
11.1.0.2.8.3 Society / Policy Level
  • Address SDOH(housing、food、education、jobs)
  • Affordable care policies
  • Anti-discrimination laws
  • Education funding
  • Community health workers
11.1.0.2.9 Patient-Centered Communication
  • Use teach-back
  • Avoid medical jargon
  • Use professional interpreters(not family)
  • Acknowledge cultural beliefs
  • Explore patient preferences
  • 22E 強調:「listen first

11.1.0.3 🔑 Mnemonic

11.1.0.3.15 SDOH 領域
  • Economic stability
  • Education
  • Healthcare access
  • Neighborhood
  • Social / community

口訣:「EEHNS - Easy NS

11.1.0.3.280/20 SDOH rule
  • 80% health outcome by SDOH + behavior
  • 20% by healthcare system

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
