Detailed Description
The standard of care published by the American Association for the Study of Liver Disease, (AASLD) do not recommend screening of asymptomatic patients for liver fibrosis so it is common that the first a patient learns of the disease is when they are diagnosed with cirrhosis. Detection at early stages of the disease process is mostly accidental as a result of other procedures.
Research has clearly established the health risks associated with liver disease and comorbidity with a wide range of other illnesses. FibroScan has been shown to be a useful test to identify asymptomatic liver disease.
The FibroScan device (Echosens) works by measuring shear wave velocity. In this technique, a 50 megahertz wave is passed into the liver from a small transducer on the end of an ultrasound probe. The probe also has a transducer on the end that can measure the velocity of the shear wave (in meters per second) as this wave passes through the liver. The shear wave velocity can then be converted into liver stiffness, which is expressed in kilopascals. Essentially, the technology measures the velocity of the sound wave passing through the liver and then converts that measurement into a liver stiffness measurement; the entire process is often referred to as liver ultrasonographic elastography. The procedure is non-invasive and presents no bio-chemical hazards as it uses only well understood ultrasound technology.
The goal of this screening study is to gather FibroScan data from the at-risk but undiagnosed population on a self-selection basis so that incidence rates can be calculated and the economics of a single function screening service can be evaluated.
The objective is to develop evidence based information to determine if noninvasive screening of at risk, comorbid people is feasible with this modality.
Furthermore, a secondary goal is to educate all participants about liver disease, lifestyle, healthy diets, organ donation, and clinical trials as part of the Foundation's larger mission of being patient advocates.
Questions Posed by this Study:
- What population demographics justify routine screening on a cost benefit basis?
- What operating cost burden is required to sustain a mobile screening project and what is the minimum utilization required to justify it?
- What portion of the asymptomatic patient with advanced disease will be willing to learn about clinical trials?
All patients will receive education about liver disease as part of the intake process. From the patient perspective, the key result will be that they receive the printed output from their FibroScan test. Interpretation of that result requires expert support. The investigators will direct patients to local medical resources where their questions can be answered, but the ideal route will be a triage through telemedicine with a hepatologist as a way to quickly direct them to proper resources. Patients with test results indicating no active disease will be offered connections to nutrition and dietary support. In all cases patients will be offered enrollment in online educational tools.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Calculate the frequency distribution and severity of steatosis stage (S0, S1, S2, S3) and liver fibrosis stage (F0, F1, F2, F3, F4) in the test population.
Time Frame: The test period will be six months and results will be reported 3 months after end of testing.
|
The frequency distribution is the percentage each stage represents of the total. Severity is described by the disease staging. Staging is not measured directly so test scores are normalized to a stage using cutoff values. The results are fat content (steatosis) and liver fibrosis (steatohepatitis) derived from test measurements of CAP score (controlled attenuation parameter) and LSM (liver stiffness measure). These are used to calculate the frequency distribution and staging of steatosis stage (S0, S1, S2, S3) and liver fibrosis stage (F0, F1, F2, F3, F4). The resulting dataset will then be assigned to a disease stage according to the breakpoints below. CAP S0 (<225) S1 (225-275), S2 (276-300), S3 (>300) LSM F0 (<7.0) F1 (7.0-7.4) F2 (7.5-9.9) F3 (10.0-13.9) F4 (>13.9) The distribution of the normalized dataset will be calculated as the percentage each bracket is of the total number of tests in that subset. |
The test period will be six months and results will be reported 3 months after end of testing.
