â€Ē H. pylori screening methods have not been included in the UHC benefit package,

Why do we have to conduct this research?

â€Ē In 2011, The research was submitted by researchers from health academics groups

To explore the cost-effectiveness of five different screening methods for H. pylori infection: 1)endoscopic gastric biopsy and rapid urease test (RUT) + Histology (If RUT is negative) ;2)urea breath test (UBT); 3)serology; 4)stool polymerase chain reaction (PCR); and 5)therapeutic diagnosis

Methods Advantage/Disadvantage

Endoscopic gastric biopsy and RUT (and histology if needed)

The gold standard of H. pylori screening is recommended by the Gastroenterological Association of Thailand

UBTSimple screening method, widely used in developed countries, but not in Thailand due to its high costs (2,500 Baht/case)

Serology Convenient for epidemiological investigation

Stool PCR Complicated sampling techniques which can be inconvenient in clinical practice

Therapeutic diagnosis Based on personal judgment of the physicians
