What is the surgical risk level for a 62-year-old male with a history of substance dependence (including cannabis and alcohol), essential hypertension, macrocytic anemia, thrombocytopenia, liver cirrhosis, and coagulopathy, who is undergoing hip surgery?

Surgical Risk Assessment for Hip Surgery

This patient is at intermediate-to-high surgical risk for hip surgery, primarily driven by liver cirrhosis with associated coagulopathy, thrombocytopenia, macrocytic anemia, and alcohol dependence—all of which significantly increase perioperative morbidity and mortality.

Primary Risk Factors

Liver Cirrhosis and Coagulopathy

• The presence of liver cirrhosis is the dominant risk factor, as operative risk correlates directly with the severity of underlying liver disease and the nature of the surgical procedure 1
• The INR of 1.3 is mildly elevated but acceptable for surgery (guideline threshold is INR <2 for surgery) 2
• However, the albumin of 3.0 g/dL suggests compromised hepatic synthetic function, indicating more advanced disease 1
• Patients with cirrhosis undergoing major orthopedic surgery face hemodynamic instability that can worsen liver function perioperatively 1

Thrombocytopenia

• The platelet count is not provided in the labs but is documented as present, which is critical for risk stratification 2
• If platelets are 50-80 × 10⁹/L, this represents a relative contraindication to neuraxial anesthesia 2
• Thrombocytopenia in cirrhosis is multifactorial (portal hypertension, hypersplenism, reduced thrombopoietin production) and indicates advanced disease 3, 4
• Up to 84% of cirrhotic patients have thrombocytopenia, and it is an independent predictor of poor prognosis 4

Anemia

• Hemoglobin of 9.8 g/dL requires pre-operative transfusion consideration, as the guideline recommends transfusion when Hb <9 g/dL or <10 g/dL with ischemic heart disease 2
• Hip surgery typically causes a hemoglobin drop of approximately 2.5 g/dL, which would bring this patient to 7.3 g/dL postoperatively—a critical threshold 2
• The macrocytic anemia (MCV 99.9) likely reflects chronic alcohol use and nutritional deficiency 2
• Two units of blood should be crossmatched given the Hb of 10-12 g/dL range 2

Alcohol Dependence

• Alcohol dependence is explicitly identified as a risk factor for significant perioperative morbidity 2
• Patients with substance abuse disorders undergoing hip arthroplasty have high rates of postoperative withdrawal delirium and psychosis (46%), late complications (25%), and poor compliance (27%) 5
• The combination of alcohol dependence and cirrhosis creates compounded risk, as these patients may experience withdrawal, have poor nutritional status, and demonstrate unpredictable perioperative behavior 5, 6

Risk Stratification Using Clinical Scoring

Model for End-Stage Liver Disease (MELD) Considerations

• While the complete MELD score cannot be calculated without creatinine and bilirubin values, the available data (INR 1.3, albumin 3.0) suggest compensated cirrhosis without ascites 1
• The MELD score provides reasonable estimation of perioperative mortality and should be calculated 1
• Surgery may be contraindicated if MELD score is very high, though the absence of ascites is favorable 1

ASA Physical Status

• This patient is ASA 3-4 based on multiple comorbidities (cirrhosis, thrombocytopenia, anemia, hypertension, substance dependence) 2
• Approximately 70% of hip fracture patients are ASA 3-4, placing this patient in a high-risk category 2

Pre-operative Optimization Requirements

Hematologic Management

• Pre-operative transfusion is strongly recommended to achieve Hb ≥10 g/dL before surgery to prevent critical postoperative anemia 2
• Platelet transfusion may be required if platelet count is <50 × 10⁹/L 2
• Coagulation parameters (PT, INR, PTT) should be optimized, though current INR of 1.3 is acceptable 2
• Avoid neuraxial anesthesia if platelets are 50-80 × 10⁹/L due to bleeding risk 2

Alcohol Withdrawal Prophylaxis

• Implement alcohol withdrawal prophylaxis protocol immediately, as withdrawal delirium occurs in nearly half of patients with substance abuse disorders 5
• Close monitoring for withdrawal symptoms, psychosis, and delirium is mandatory perioperatively 5

Anesthetic Considerations

• General anesthesia with invasive blood pressure monitoring is preferred over neuraxial techniques given thrombocytopenia and coagulopathy 2
• Avoid hypotension, as hemodynamic instability worsens liver function 1

Common Pitfalls to Avoid

• Do not proceed without calculating MELD score and Child-Pugh classification, as these guide surgical candidacy 1
• Do not assume normal bleeding risk based on "acceptable" INR alone—the combination of cirrhosis, thrombocytopenia, and coagulopathy creates multifactorial bleeding risk 2, 4
• Do not underestimate alcohol withdrawal risk—implement prophylaxis before symptoms emerge 5
• Do not delay surgery for minor INR elevation (current INR 1.3 is acceptable), but do optimize anemia and thrombocytopenia 2
• Do not use restrictive transfusion triggers in this patient—the combination of cirrhosis and expected surgical blood loss mandates higher hemoglobin targets 2

Postoperative Monitoring

• Intensive monitoring for bleeding, hemodynamic instability, and hepatic decompensation is essential 1
• Monitor for alcohol withdrawal, delirium, and psychosis for 48-72 hours postoperatively 5
• Recheck hemoglobin within 24 hours and maintain Hb >7-8 g/dL, with lower threshold for transfusion given cirrhosis 2, 7
• Early detection of complications is critical for improving outcomes in cirrhotic patients 1
