A 58-year-old man with a 15-year history of type 2 diabetes mellitus (HbA1c 8.2%) and hypertension (on amlodipine 5 mg daily, BP 138/86 mmHg) presents for elective laparoscopic cholecystectomy. He denies chest pain, dyspnea, or palpitations. Fasting blood glucose is 156 mg/dL. ECG shows normal sinus rhythm with no ischemic changes. Echocardiography performed 2 years ago was normal. What is his ASA Physical Status classification?

## ASA Physical Status Classification **Key Point:** This patient has multiple systemic diseases (diabetes with suboptimal control, hypertension) that are well-controlled on medication but impose functional limitations. He meets criteria for ASA III. ### Classification Criteria | ASA Class | Definition | Examples | | --- | --- | --- | | **ASA I** | Healthy, no systemic disease | Young, fit, no comorbidities | | **ASA II** | Mild systemic disease, no functional limitation | Controlled HTN, well-controlled DM, mild obesity | | **ASA III** | Severe systemic disease with functional limitation | Poorly controlled DM, HTN with end-organ damage, CAD, COPD | | **ASA IV** | Severe systemic disease with constant threat to life | Unstable angina, recent MI, severe sepsis, decompensated heart failure | | **ASA V** | Moribund, not expected to survive without surgery | Massive trauma, ruptured AAA, septic shock | | **ASA VI** | Brain-dead organ donor | — | ### Why ASA III? 1. **Multiple systemic diseases present:** Type 2 diabetes (HbA1c 8.2% = suboptimal control) + hypertension 2. **Functional implications:** Diabetes with HbA1c >8% indicates inadequate glycemic control, increasing perioperative risk (infection, hyperglycemia, delayed healing) 3. **Well-controlled on medication but still at risk:** Although BP is near-target and patient is asymptomatic, the presence of two chronic conditions with one being poorly controlled (HbA1c 8.2%) places him in the "severe systemic disease" category 4. **No acute life threat:** Excludes ASA IV (would require unstable angina, recent MI, or symptomatic cardiac disease) **High-Yield:** The distinction between ASA II and ASA III hinges on **functional limitation or severity of disease control**. HbA1c >8% in a diabetic patient undergoing surgery is considered inadequately controlled and elevates risk; this patient therefore has "severe systemic disease" (ASA III) rather than "mild systemic disease" (ASA II). **Clinical Pearl:** ASA classification is **not** based on age alone, comorbidity count, or lab values in isolation—it is a **holistic assessment** of the patient's physiologic reserve and disease severity. A 58-year-old with well-controlled HTN alone might be ASA II; add poorly controlled diabetes and he becomes ASA III.
