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.
Insights
Infection control practices in Indian tuberculosis microscopy centers show gaps. Addressing these shortcomings is crucial to protect laboratory staff and the public from infection transmission.
Area of Science:
- Public Health
- Infectious Disease Control
- Laboratory Science
Background:
- The Revised National Tuberculosis Control Programme in India aims to increase tuberculosis case detection via designated microscopy centers (DMCs).
- Standard precautions for infection control in DMCs are vital for preventing disease transmission to laboratory personnel and the public.
- External evaluation of infection control practices in Indian DMCs has been limited.
Purpose of the Study:
- To assess knowledge, facilities, and compliance with infection control practices (ICP) in DMCs.
- To identify areas for improvement in infection control within tuberculosis diagnostic settings.
Main Methods:
- A cross-sectional study was conducted in 2015, evaluating all 38 DMCs in Kannur district, Kerala, India.
- Data were collected using structured observations and interviews with laboratory technicians.
- The study assessed knowledge, available facilities, and adherence to infection control protocols.
Main Results:
- Only 29% of laboratory technicians demonstrated satisfactory knowledge of infection control.
- Satisfactory infection control facilities were present in 61% of DMCs, with adherence observed in 45%.
- Government DMCs showed better knowledge, while private DMCs excelled in facilities and biomedical waste management.
Conclusions:
- Significant shortcomings exist in infection control practices within designated microscopy centers.
- Urgent interventions are needed to improve infection control, particularly given the high-risk environment for laboratory technicians.
- Enhancing infection control is essential for safeguarding healthcare workers and preventing community-wide disease spread.

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,...
