7.3 🩺 內科專科考前版

對象:R2-R3 / Fellow,準備台灣內科專科考。專科考會考 IOM reports + Donabedian + 台灣 TJC 認證 + 健保 P4P。


7.3.0.1 📌 一頁重點整理

  • IOM 1999 / 2001 / 2015 三大 reports 是 modern patient safety 起源
  • Reason’s Swiss Cheese Model + Donabedian SPO 是質量管理理論基礎
  • Evidence-based interventions:CPOE -55% med error、Pronovost bundle 大幅降 CRBSI
  • 22E 強調 transition / handoff 是 inpatient/outpatient adverse event 高風險點
  • 2023 NEJM Bates et al.:2 decades since IOM,progress mixed
  • 📍 台灣:醫策會(TJC)、TJCHA 認證、健保 P4P、病安通報系統 (TPR)

7.3.0.2 📜 22E vs 21E 主要差異

項目 21E 22E
AE rate Harvard MPS 3.7% 強化「近年 1/4 admissions」
2023 Bates NEJM 引述(2 decades since IOM)
Diagnostic errors 強化(cross-ref Ch 10)
AI safety risk 新增(automation bias)
Health equity in safety 強化

7.3.0.3 🧠 深度概念

7.3.0.3.1 Reason’s Swiss Cheese Model 應用

每層 defense: 1. Hard defenses:physical(locked room、interlocks) 2. Soft defenses:human factors(checklist、protocol) 3. System defenses:culture、reporting

Latent failures」(潛在錯誤): - 系統設計缺陷 - 平時無症狀 - 一旦對齊 → catastrophe - 例:藥房擺位、ED 流量、人力配置

Active failures」(active errors): - 個人在現場做錯 - 多有 latent contributing factors

7.3.0.3.2 James Reason’s 「Just Culture」
  • Distinguish:
    • Human error(不該罰)
    • At-risk behavior(教育)
    • Reckless behavior(懲處)
  • 平衡 accountability vs blame-free
7.3.0.3.3 High Reliability Organization (HRO) Principles

借鑑核能、航空: 1. Preoccupation with failure 2. Reluctance to simplify 3. Sensitivity to operations 4. Commitment to resilience 5. Deference to expertise

→ Hospital 朝 HRO 模式發展

7.3.0.3.4 Safety Culture Survey
  • AHRQ Hospital Survey on Patient Safety Culture
  • Domains:teamwork、communication、handoffs、management support
  • 連結 outcome:高 safety culture 醫院 → 低 AE rate

7.3.0.4 🩺 22E 提到的 Quality Improvement Tools 詳解

7.3.0.4.1 Plan-Do-Check-Act (PDCA / PDSA)
  • 「Tests of change」鼓勵小範圍 iteration
  • Statistical Process Control charts 監測效果
7.3.0.4.2 Chronic Care Model (Wagner et al.)

6 components: 1. Self-management support 2. Delivery system design 3. Decision support 4. Clinical information systems 5. Community resources 6. Health system organization

→ 對 DM HbA1c 改善:team changes + case manager 最有效(meta-analysis)

7.3.0.4.3 Bundles 應用實例
Bundle 措施 Outcome
CRBSI Pronovost Hand hygiene、full barrier、chlorhexidine、avoid femoral、daily review Michigan ICU CRBSI 大幅降
VAP HOB 30°、SBT、DVT prevention、PUD prevention、daily sedation VAP rate ↓
WHO Surgical Safety Pre-induction、pre-incision、pre-departure Surgical mortality ↓
Sepsis Lactate、blood culture、broad-spectrum、IV fluid 1h Sepsis mortality ↓
7.3.0.4.4 SCAMPs (Standardized Clinical Assessment and Management Plans)
  • Clinician-developed
  • Continuous data feedback loop
  • 不同於 rigid guidelines
  • 例:Boston Children’s Hospital 應用於多 condition
7.3.0.4.5 I-PASS Handoff Tool
  • Illness severity
  • Patient summary
  • Action list
  • Situation awareness
  • Synthesis
  • 證據:medical errors -23%, preventable AE -30%

7.3.0.5 🔍 特殊情境

7.3.0.5.1 1. ECQM (Electronic Clinical Quality Measures) Migration
  • 從 claims-based → EHR-based
  • CMS 2024+ 主推
  • 優點:real-time、accurate
  • 限制:interoperability、data quality
7.3.0.5.2 2. AI in Patient Safety
  • ML for sepsis prediction(Epic Sepsis Model)
  • Limitations:bias、generalizability、alert fatigue
  • 22E:「emerging, validation needed」
7.3.0.5.3 3. Diagnostic Errors as 主要 patient safety issue
  • IOM 2015 把 diagnostic error 列為 major patient safety
  • 估計每人一生至少 1 次
  • Solutions:decision support、second opinion culture、checklists
7.3.0.5.4 4. Health Equity in Safety
  • BIPOC 病人 AE rate 較高
  • Language barrier、health literacy
  • 22E 強調 systemic intervention
7.3.0.5.5 5. Patient Engagement in Safety
  • “Patient-and-family-centered care”
  • Encourage speak up
  • Discharge teach-back
  • Open notes / records sharing
7.3.0.5.6 6. Hospital-Acquired Conditions (HACs)
  • CMS no longer pays for some preventable HACs
  • 包括:CAUTI、CRBSI、pressure ulcer stage III/IV、surgical site infection、retained foreign object 等
  • 強烈經濟誘因 → 大幅降低 rate
7.3.0.5.7 7. Burnout & Safety
  • Provider burnout → patient safety risk
  • ACGME 工時、wellness programs
  • WHO 將 burnout 列為 occupational phenomenon (2019)

7.3.0.6 🔬 22E 提到的新進展

7.3.0.6.1 EHR-based Safety Surveillance
  • Trigger-based active surveillance
  • Replaces sporadic reporting
  • 例:unexpected ICU transfer、naloxone use、Vit K admin
7.3.0.6.2 Patient-Generated Data
  • Wearables、apps
  • Continuous monitoring → outpatient safety
7.3.0.6.3 Telemedicine Safety
  • Remote monitoring 對 chronic disease quality
  • 但 isolation 增加 missed signals 風險
7.3.0.6.4 Predictive Analytics
  • Sepsis prediction
  • Readmission prediction
  • AKI prediction
  • 但 alert fatigue + false positive 仍 issue

7.3.0.7 📍 台灣 Context 專區

7.3.0.7.1 醫策會(TJCHA / Joint Commission of Taiwan)
  • 1999 年成立
  • 醫院評鑑(Joint Commission Taiwan)
  • 與 USA Joint Commission 接軌
  • 認證制度(醫學中心、區域醫院、地區醫院)
7.3.0.7.2 TJCHA 病人安全 8 大目標(依年度更新)
  • 跨院年度目標:手術安全、用藥安全、跌倒、感染、handoff 等
  • 各醫院須符合 + 通報
7.3.0.7.3 病人安全通報系統 (TPR)
  • 台灣病人安全通報系統(衛福部 + 醫策會)
  • 2004 年起
  • 跨院共享 lessons learned
  • Safety II」哲學:學習成功,不只報失敗
7.3.0.7.4 健保 P4P 計畫
  • DM、HTN、CKD、Asthma、COPD、HBV/HCV、TB
  • 強調 process + outcome metrics
  • 比例:~5-10% reimbursement
  • 證據:HbA1c 改善但 cost-effectiveness 待 evaluation
7.3.0.7.5 TMA 醫師執業守則
  • 與 Charter on Medical Professionalism 一致
  • 強調 patient welfare、autonomy、social justice
7.3.0.7.6 工時規範
  • ACGME 在台灣不直接適用
  • 衛福部 + TMA 自訂:PGY < 80 hr/wk(與 ACGME 一致)
  • 主治醫師工時無上限(爭議)
7.3.0.7.7 醫療糾紛調解
  • 2017 起 「醫療糾紛調解先行」
  • 防止 defensive medicine 蔓延
  • 與 medical error reporting 相關

7.3.0.8 🌟 Clinical Pearls (8 條)

  1. 「Don’t blame the individual」:error 多源於 system;個人懲處 → 隱匿
  2. Discharge transition 是 highest-risk period:要 active follow-up + medication reconciliation
  3. Sentinel event reporting:每個 unexpected death / serious harm 都要 root cause analysis
  4. Bundles 是 all-or-none:80% compliance ≠ 80% benefit;要全套執行
  5. Speak-up culture:低階員工敢挑戰高階決策 → safer
  6. Alert fatigue 真實:CPOE alert 太多 → 醫師自動 dismiss
  7. Workplace burnout = patient safety issue:必須 system-level intervention
  8. Health equity is patient safety:BIPOC 病人 AE 較高,需 specific 介入

7.3.0.9 ⚠️ 老闆地雷區

  1. 個人責怪文化:error → 罵人 → 隱匿
  2. 不報 near-miss:失去 learning opportunity
  3. Workaround culture:跳過 safety check 「速度優先」
  4. Alert fatigue 不認:自動 dismiss 重要 alert
  5. Bundles 只做部分:失去 effectiveness
  6. Discharge 不教 medication:30-day readmission 高
  7. Communication failure 不重視:handoff 不結構化

7.3.0.10 🎓 內科專科考重點預測

7.3.0.10.1 高機率題型
  1. IOM reports(年代 + 主題)
  2. Donabedian 三層
  3. Swiss cheese model
  4. Slip vs Mistake 區辨
  5. Bundles 應用(CRBSI、VAP、sepsis)

  • Ch 1 The Practice of Medicine
  • Ch 4 Decision-Making:cognitive errors
  • Ch 10 Diagnosis Errors
  • Ch 9 Physician Well-Being:burnout & safety
7.3.0.10.3 易答錯
  • Safety = Quality(錯)
  • Spontaneous reporting > 50% sensitivity(錯,~5%)
  • 80-hr workweek 解決所有 fatigue(錯,extended-duty shifts 仍問題)
