Abstract
ObjectiveTo evaluate risk factors for developing latent tuberculosis (LTB) in Thai nurses. MethodsA comparison study was conducted at Srinagarind Hospital, Khon Kaen, Thailand. Clinical factors were compared between persons with tuberculin conversion and those without tuberculin conversion identified by tuberculin skin test. ResultsThere were 173 eligible persons with the LTB (34.7%). There were five workplaces where participants worked regularly including the general ward, surgical ward, pediatric ward, medical ward and critical care ward. In a multivariate model, two factors were significantly associated with LTB including age and history of tuberculosis in colleagues. The adjusted odds ratio (95% confidence interval) of both variables were 1.056 (1.004–1.104) and 0.202 (0.044–0.941). ConclusionsOlder age is associated with latent tuberculosis in nurses. LTB should be screened routinely and treated if diagnosed for nurses.
