The Frugal Diagnostician

Facilitator Instructions:

Divide the group into 2-4 teams. Provide each team with identical patient. Each team discusses the case and can order a round of tests each “day”, during up to 3 “days” of hospitalization. For each test the team orders on a particular day, the facilitator will provide the team with the charge for each test and test result. This information is to be shared prior to decision-making and orders for the “next hospital day”.

Each day of hospitalization also incurs a room charge. If a team feels they have reached a diagnosis prior to day 3, they may discharge the patient to prevent additional hospital charges.

The goal is to correctly diagnose the patient in the most cost efficient manner. Thus, the team that arrived at the diagnosis with the lowest bill (by adding up their charges) wins.

Charges should be obtained from the chargemaster of the trainee’s hospital.

The Frugal Diagnostician #1

Your task is to correctly diagnose the patient in the most cost effective manner. Please read the history and physical below. Then, make a list of laboratory/imaging tests you would like to order. The test results will be given to you along with a charge for one night in the hospital. At that point, you can submit a diagnosis and discharge your patient, or keep them in the hospital another night and order more testing. After 3 nights in the hospital, the patient must be discharged and a diagnosis submitted. Upon discharge, your patient’s total bill will be calculated. The team that correctly diagnoses the patient with the lowest bill, will be crowned the frugal diagnostician.

Conclusion:

2. Reversed flow demonstrated within the main and right portal veins, suggestive of portal hypertension.

3. Large ascites.

CT Triple Phase Abdomen

Impression:

1. Innumerable hepatic masses which show enhancement characteristics compatible with diffuse multifocal hepatocellular carcinoma. Probable tumor thrombus within the right portal vein and multiple branches.

2. Hepatic artery-portal venous shunt, likely related to intratumoral shunt from the dominant right hepatic lobe mass.

3. Findings of cirrhosis and portal hypertension with large volume of ascites.

MRI Abdomen:

1. Multifocal hepatic masses likely hepatocellular carcinoma.

2. Cirrhosis and portal venous hypertension.

Diagnosis: Cirrhosis (from Hepatitis C with Hepatocellular Carcinoma)
