Experiences of Screening for Human Immunodeficiency Virus, Viral Hepatitis B, and Viral Hepatitis C Infections at a Hospital in Thailand: Test Utilization and Outcomes

Abstract

BACKGROUND To prevent the transmission of HIV and hepatitis B and C viruses, early detection is necessary; however, in the early stage, most infected people are symptomless. Screening for these infections should be targeted to certain clinical settings to increase the early detection rate. MATERIAL AND METHODS This retrospective study was conducted by analyzing data from patients' medical records to determine how the screening tests for these viral infections were utilized and what the clinical outcomes from the test utilization were. RESULTS From 11 676 collected records, the screening tests for HIV, HBV, and HCV infections were utilized in 871, 556, and 236 cases, respectively. The tests for HIV and HCV were utilized the most in people with chronic non-infectious diseases, while the test for HBV infection was utilized the most in pregnant women. The positive results of these tests were highly found in the group of patients with acute non-infectious diseases. HIV infection was newly detected in 1.38% of patients, and HBV and HCV infections were newly detected in 5.58% and 2.12%, respectively. CONCLUSIONS Screening for HIV and HBV infections was performed according to the guidelines of the national HIV and HBV programs. The Outpatient Department (OPD) and medical ward may be the most appropriate clinical settings for HIV screening because most patients are there and blood tests are often ordered there, too. The national programs helped slow the rates of HIV and HBV infections in this community.
