OBJECTIVE: The purpose of study was to increase the case detection and treatment
success rate of tuberculosis through DOTS strategy.
DESIGN: This is an ongoing prospective study.
SETTINGS: The study was carried out at DOTS section of Chandka Medical College
Hospital (CMCH) Larkana From 1st January 2004 to 30th June 2005 .
PATIENTS AND METHODS: The patients visited the DOTS section of CMCH, Larkana
from 1st January 2004 to 30th June 2005 with the history of cough for 03 or more
weeks, less than 03 weeks or of uncertain duration with haemoptysis or history of
contact with sputum positive (+ve) TB patients, were registered for the study.
RESULTS: Out of the registered 951 TB cases, 537 (56.5%) were males and 414
(43,5%) females . The male to female ratio was 1.2:1. The 358 (83%) cases were noted
between the 15-54 years of age. The case detection rate of TB patients was 78%. The
over all treatment success rate of pulmonary TB cases was 78% with 11% defaulted
and 6% transferred (outstation) cases.
CONCLUSION: In order to achieve the targets for TB control in the face of new
challenges, implementation of DOTS strategy is the one of the best mode which provide
the patients all necessary requirements needed for the cure.
KEY WORDS: TB, DOTS.
Tuberculosis (TB) is an important health problem and nearly one third of world population
is either infected or at risk of developing the disease.1 Each year, it is estimated that
03 million people die of tuberculosis and that 08 million new cases occur.2 Keeping
in view of its importance as a major public health problem World Health Organisation
(WHO) declared TB a global emergency in 1993.3 The resurgence of TB in the past
decade has been largely associated with poverty. 4 It remains the most frequent infection
observed in socio-economically deprived populations within which effective long term
treatment is difficult to accomplish.5 The co-infection with the human immunodeficiency
virus (HIV) significantly increases the risk of developing TB.6 The data
