A Pilot Programme for Tuberculosis Screening in Immigrants at Primary Care

Abstract

Immigrants from countries with a high prevalence of Tuberculosis (TB) may constitute a source of infection. The aim of the present study was to describe a Tuberculosis (TB) screening programme at a primary health care centre directed at immigrants from countries with a high prevalence of TB. This was a descriptive study conducted at a primary health centre in Barcelona between 2009 and 2012 for immigrants from countries with a TB incidence > 100/100,000. They were invited to join the TB detection programme on registering at the primary health care centre when a reference nurse conducted a survey on socio-health data, performed a Tuberculin Skin Test (TST) and requested a chest X-ray. Interferon Gamma Release Assays (IGRA) were applied in individuals with positive TST or an abnormal X-ray. Ninety-one (70.5%) of 129 individuals, aged 29.8 ± 9.8 years, who entered the programme, were men, 60 (46.5%) were from Pakistan and 3 reported previous TB. Eighty-six (66.7%) immigrants completed the study protocol. Three cases (2.3%) of TB were diagnosed and 29 (30.5%) had latent TB infection. Seven chest X-rays yielded other non-TB radiological changes. This TB screening programme should aid early detection of TB and LTBI among immigrants from high-TB prevalence countries on first registering at the primary health care centre.
