Background:
One of the strategies of the Revised National Tuberculosis Control Programme in India to achieve tuberculosis control is by increasing case detection through a nationwide network of designated microscopy centres (DMC). Practice of standard precautions for infection control in these DMCs is very important to prevent transmission of infection not only to the laboratory personnel, but also to the general population. However, in India this has not been evaluated by an external agency.
Method:
A cross-sectional study was carried out to assess knowledge, facilities and compliance regarding infection control practices (ICP) in all 38 DMCs in Kannur district, Kerala, India, in 2015. Using observations and interviews, the investigators collected data in a structured format.
Results:
Overall knowledge about infection control was found to be satisfactory among 29% of laboratory technicians. Overall facilities for infection control were satisfactory in 61% of the DMCs, while adherence to ICP was satisfactory in 45% of the DMCs. Knowledge regarding ICP was better in government DMCs, whereas facilities for ICP and adherence to biomedical waste management guidelines were better in private DMCs.
Conclusion:
Given the higher risk of infection among laboratory technicians, there is an urgent need to address the shortcomings in infection control practices.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
