Esоphаgeаl Vаrices 1. Backgrоund Definitiоn: Dilated submucosal veins in the distal esophagus resulting from portal hypertension, most commonly due to cirrhosis. Pathophysiology: Portal venous pressure increases → blood diverted through collateral veins between the portal and systemic circulation (especially via the left gastric → esophageal veins). These veins become engorged and fragile, predisposing to life-threatening upper GI bleeding. Epidemiology: Occurs in ~50% of patients with cirrhosis; risk increases with severity of liver disease (Child-Pugh class). First bleed carries a 30–50% mortality rate if untreated. Major causes: Cirrhosis (alcoholic, viral, NAFLD/MASH). Portal vein thrombosis (less common). 2. History Symptoms: Often asymptomatic until rupture. Acute bleeding presentation: Hematemesis, melena, hematochezia (massive bleed), syncope, or shock. May have preceding signs of portal hypertension (ascites, jaundice, splenomegaly). Risk factors for bleeding: Large varices, high portal pressure gradient, alcohol use, infection, coagulopathy, poor liver function. 3. Exam Findings General: Tachycardia, hypotension, pallor (if active bleeding). Abdomen: Ascites, hepatomegaly, splenomegaly, caput medusae. Skin: Spider angiomas, jaundice, palmar erythema (signs of chronic liver disease). Mental status: Possible hepatic encephalopathy. 4. Making the Diagnosis Gold standard: Upper endoscopy (EGD) — identifies and grades varices; can perform therapy (band ligation or sclerotherapy). Initial evaluation: Suspected variceal bleed → resuscitate first, then perform urgent endoscopy within 12 hours. Adjunct testing: CBC (anemia, thrombocytopenia), CMP (liver function), INR, and type/crossmatch. Ultrasound or CT may show portal hypertension but do not diagnose varices directly. 5. Management A. Acute Bleeding (Emergency) Stabilization: IV fluids, blood transfusion (goal Hgb ~7–8 g/dL), correct coagulopathy. IV octreotide (splanchnic vasoconstriction to reduce portal pressure). IV ceftriaxone for infection prophylaxis. Definitive therapy: Endoscopic band ligation (preferred) or sclerotherapy during EGD. Refractory bleeding: TIPS (transjugular intrahepatic portosystemic shunt) to decompress portal system. B. Secondary Prophylaxis Nonselective beta-blockers (propranolol or nadolol) ± repeat band ligation to prevent rebleeding. Avoid alcohol and manage underlying cirrhosis. C. Primary Prophylaxis (No prior bleed) Screen all cirrhotic patients with EGD. Start nonselective beta-blockers or schedule prophylactic band ligation if medium/large varices are found. Question A 54-year-old man with a history of alcoholic cirrhosis presents to the emergency department with vomiting of bright red blood. His blood pressure is 90/60 mm Hg and pulse is 112/min. Physical examination shows jaundice, spider angiomas, and mild ascites. After two large-bore IV lines are placed and blood is sent for type and crossmatch, which of the following is the most appropriate next step in management?

Which оf the fоllоwing is аn operаtionаl element that should be included in a migration path for a hospital with an existing EHR and wishing to improve its population health data for value-based care reimbursement?
The depаrtment оf surgery hаs аcquired an analytics engine tо enable it tо provide predictive information at the point of care via the EHR. However, the department is struggling to get physicians to use the functionality because it does not have support staff to program or train users. This situation refers to the fact that the project plan did not illustrate _____.
