The Indian Council of Medical Research and the Central Drugs Standard Control Organization have taken a giant leap towards tackling one of the biggest health threats by introducing India's first guidelines for developing high-end testing machines. This is aimed at tackling the emerging challenge of anti-microbial resistance (AMR), which has toughened infection treatment.

What is anti-microbial resistance and why it happens

Anti-microbial resistance occurs when microbes such as bacteria, viruses, fungi, and parasites adapt to resist the actions of medications; this makes the usual treatments ineffective or useless. Consequently, infections that are difficult to treat create a high potential for disease transmission, severe disease, and mortality.

The central government is focusing on combating this problem by creating a comprehensive 59-page document. This is a guide meant to assist innovators in the development and validation of new diagnostic machines. Such machines can identify pathogens—the bad guys causing infections—within a short time frame and identify medicines that will probably work against them.

What's in the guidelines

The guidelines, prepared by the AMR coordination unit of ICMR, outline a clear path for developing and testing new diagnostic tools. They explain the necessary steps to ensure these tools are accurate, reliable, and affordable. The document also shows the importance of diagnosing infections quickly to ensure the correct use of antibiotics and other treatments.

Rajeev Singh Raghuvanshi, the Drug Controller General of India, said in the document’s foreword how crucial these tools are. He noted that delays in diagnosis and the lack of affordable testing contribute to the misuse of antibiotics, worsening the problem of AMR.

How will the guidelines help

The new document will fill the gaps in the current system by providing a standardized framework for validating diagnostic tools. This will ensure that the tests are reliable and can be widely used in India's healthcare system.

According to Rajiv Bahl, Director General of ICMR, with advances in molecular techniques, the ability to design better diagnostic tests is possible, but lack of guidelines has held up their introduction in the health system. This paper intends to harmonize the process to facilitate new diagnostics in easy testing and utilization.

What is validation

Validation is testing new diagnostic tools to ensure they are working correctly. The guidelines outlined criteria such as accuracy, precision, and ability to identify the right pathogens or their resistance to drugs consistently. It also explained how to conduct cost-effectiveness studies to make these tools affordable.

The document suggests that validation studies should ideally be conducted at multiple sites across different regions of the country to ensure the tools are effective everywhere. If this isn't possible, testing should happen at least in two different locations to account for geographic variations.

The guidelines further cover anti-microbial susceptibility testing that determines whether particular antibiotics will have an effect on the pathogen or not. Each type of microorganism tests at least 100 samples from clinical cases to ensure results are reliable; this helps choose the right antibiotics when treating infections.

The introduction of these guidelines is a major stride in India's fight against anti-microbial resistance. In doing so, the ICMR and CDSCO are giving a clear direction to the development and validation of new diagnostic tools, thus giving the way for more effective treatment of infectious diseases.
