RESUMO
SETTING: The penitentiary system of the ex-USSR state of Georgia. OBJECTIVES: To measure the prevalence of active pulmonary tuberculosis and drug-resistant disease among prisoners. To identify factors associated with active tuberculosis and multidrug resistance (MDR). DESIGN: A comprehensive multiphasic screening survey for tuberculosis. RESULTS: The prevalence of smear- or culture-positive tuberculosis was 5995 per 100,000 prisoners (n = 448 cases among 7473 inmates). Of all the strains, 215 (77.9%) were resistant to at least one drug and 37 (13.0%) were MDR. Independent risk markers associated smear- or culture-positive tuberculosis with included prison stay of 2 years or more, body mass index <20 kg/m2, accommodation in a large size prison, previous anti-tuberculosis treatment, cough of 2 weeks or more and loss of appetite. Risk markers associated with MDR were a prison stay of less than 2 years and being over 25 years of age. CONCLUSIONS: In Georgia, the excess risk for tuberculosis among prisoners is unprecedented, suggesting that prisons represent a significant reservoir of tuberculosis. Only a comprehensive strategy for tuberculosis control in prisons, including prison reform, control of anti-tuberculosis drugs, and prompt and efficient diagnosis and treatment of patients can have an impact on the tuberculosis burden in the prison system.
