Study of Streptococcus Pneumoniae Types in Adults Hospitalized with Community-Acquired Pneumonia in Hong Kong Using a Urine Test

What this Trial Is About

This research aims to understand how common different types of pneumococcus pneumoniae are in adults hospitalized with community-acquired pneumonia CAP. It is a non-interventional, observational study conducted at a single center. The study focuses on identifying pneumococcal serotypes using a urinary antigen test to better inform treatment approaches. Participants who are admitted to medical wards with suspected pneumonia, chest infection, or fever will be invited to join. Those who consent will provide a urine sample of about 40 ml. This urine will be tested locally and then sent to a commercial lab for detecting pneumococcal pneumoniae and determining its serotypes using a urinary antigen assay. Patients will continue to receive usual care from their clinical teams, with the study team only collecting urine samples and not interfering with treatment. Any positive findings will be shared with clinical teams for appropriate management. During the study, participants will be involved mainly in providing urine samples for testing. Researchers will track the presence and types of pneumococcal bacteria using these samples over two years. The study will observe patients data without altering their treatment and aims to determine the prevalence of pneumococcal serotypes in hospitalized adults with CAP. The total participation time varies depending on hospital admission and care.
