TL;DR

This study examines the factors influencing latent tuberculosis infection rates among hospitalized patients in Suzhou, China.

Contribution

Identifies specific demographic and clinical factors affecting latent TB infection detection in a Chinese hospital setting.

Findings

39.05% of 6692 hospitalized patients were diagnosed with latent tuberculosis infection.

Sex, age, AIDS status, testing time, lymphocyte count, and neutrophil count significantly influence LTBI detection.

Hepatitis B, diabetes, hypertension, silicosis, and monocyte count did not significantly affect LTBI detection.

Abstract

China is a country with a high burden of tuberculosis (TB). It is vital to reduce the number of new cases of TB in China. We aimed to examine and investigate the distribution and affecting factors of the latent tuberculosis infection (LTBI) detection rate in hospitalized patients in Suzhou, Jiangsu Province.

We analyzed the link between LTBI and patients’ information, disease diagnosis, and blood routine indices of hospitalized patients at the Fifth People’s Hospital in Suzhou from January 1, 2018, to March 31, 2024.

Results indicated that of the 6692 patients included in the study, 39.05% of them were diagnosed with LTBI. Multivariate analysis revealed that sex, AIDS status, testing time, age, lymphocyte count, and neutrophil count were influencing factors for the detection of LTBI ( p < 0.05). However, hepatitis B, diabetes, hypertension, silicosis and monocyte count did not significantly influence LTBI detection.

Sex, AIDS status, testing time, age, lymphocyte count, and neutrophil count were influencing factors for the detection of LTBI.
