Summary
Most Chinese-speaking patients were underscreened for hepatitis B virus (HBV) infection, despite 65% receiving screening. Provider knowledge and awareness of HBV risks in this population need improvement.
Area of Science:
- General Medicine
- Hepatology
- Public Health
Background:
- Hepatitis B virus (HBV) infection poses a significant risk to specific ethnic groups.
- The screening practices for HBV among Chinese-speaking patient populations in academic general medicine settings are not well-documented.
Purpose of the Study:
- To determine the HBV screening rates among Chinese-speaking patients.
- To identify factors associated with HBV screening in this demographic.
- To assess general medicine providers' knowledge and screening practices for HBV.
Main Methods:
- A retrospective cohort study was conducted to analyze HBV screening status in Chinese-speaking patients.
- A survey was administered to general medicine providers to evaluate their knowledge of HBV and screening behaviors.
Main Results:
- 65% of Chinese-speaking patients received HBV screening.
- Screening was associated with marital status and duration of clinic visits.
- Providers with Asian language proficiency and better knowledge of HBV risk factors/guidelines were more likely to perform screening.
Conclusions:
- Chinese-speaking patients are underscreened for HBV in this academic general medicine setting.
- Providers often underestimate the HBV risks associated with Chinese ethnicity.
- Educational interventions are necessary to enhance provider risk assessment and adherence to HBV screening guidelines.

01:25Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.

01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
01:22Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
01:17Transmission-based Precautions I: Contact, Enteric, and Droplets
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
