An Epidemiological Profile of Previously Treated Patients Registered in Tuberculosis Units in Urban Visakhapatnam

Abstract

Background: Tuberculosis (TB) remains a major global public health problem. Retreatment patients havehigher risk of drug resistance compared with new cases. The objective of the study is to describe the typesof retreatment (previously treated) patients and assess the Socio demographic characteristics, co morbidand behavioural conditions of retreatment patients and to identify the factors associated with relapseunder Revised National Tuberculosis Control Program ( RNTCP) in the tuberculosis units located in UrbanVisakhapatnam. The main aim of the study is to study epidemiological profile of previously treated patientsto identify the factors which make tuberculosis patients prone for retreatment so that necessary action canbe taken.Methods: This is an Observational Analytical Cross-sectional study done in Tuberculosis units in GVMC. All thesubjects(193) who were registered as Previously treated patients in TUs during the second and third quarter ofthe year 2016 i.e April to September 2016. A pretested semi structured schedule was administered. Categoricaldata was analysed by Chi square test. Quantitative variables were represented as means and standard deviation.Unpaired t test was used for testing statistical significance in quantitative data.Results : Among 193 study subjects 168 (87%) were having pulmonary TB and remaining 25 (13%) were havingextra pulmonary TB. Majority of the study participants, 141 (73%) were males whereas only 52 (27%) were females.Relapse patients were 125(64.9%) Defaulters were 12 (6.2%), Treatment failure was 9 (4.6%) and Others previouslytreated were 47 (24.3%). Chi square test was used for testing statistical significance of association betweencategorical variables.Conclusion: Socio demographic factors, behavioural and co morbid factors have an effect on Relapse andmodifying these risk factors may bring about favourable outcomes. There is further need for exploring the reasonsfor high rates of relapse.
