Knowledge about tuberculosis among pulmonary tuberculosis patients: A cross-sectional study from Uttarakhand

Background: Tuberculosis (TB) is a major health problem in India. The Revised National TB Control Programme (RNTCP) is working towards elimination of TB in the country by 2025. As the RNTCP relies on passive case finding, it is crucial for the success of the RNTCP that TB patients have knowledge about their disease. The present study aimed to assess the knowledge of TB among pulmonary TB (PTB) patients. Materials and Methods: A cross-sectional questionnaire based study using a pretested semi-structured questionnaire among new and previously treated PTB patients at Haldwani Block of Nainital District of Uttarakhand State of North India. Data was analyzed using the software Epi Info version 7.2.0.1. Results: A total of 111 PTB patients with mean age of 36.3 years were included for final analysis. Only 43.2% PTB patients were aware that TB is caused by germs, 48.6% knew that it is not a hereditary disease. Only 13.5% PTB patients knew that vaccine is available and majority (68.5%) were aware of covering mouth and nose while coughing and sneezing for prevention of the disease. Overall, only two-third (65%) patients had good knowledge about TB. Conclusions: About one-third of PTB patients had poor knowledge about TB. This highlights that to achieve elimination of TB, RNTCP needs to change the present information, education, and communication (IEC) system which is based on a bio-medical framework, and to design a culturally sensitive health education system. Alternatively, the Programme needs to shift from passive case finding to active case finding strategy.
