Antimicrobial Resistance (AMR)
Antimicrobial resistance occurs when bacteria, viruses, fungi, and parasites evolve to resist the drugs designed to kill them, rendering standard treatments ineffective. The WHO identifies AMR as one of the top 10 global public health threats. In India, hospital-acquired infections caused by drug-resistant organisms such as Acinetobacter baumannii and Pseudomonas aeruginosa show resistance rates of 57-80% to carbapenem antibiotics in some tertiary care hospitals.
- Pseudomonas aeruginosa accounts for approximately one-fifth of hospital-acquired pneumonia cases globally.
- Ventilator-associated pneumonia (VAP) has a global prevalence of about 15.6%, with an incidence of 5-20 cases per 1,000 mechanical ventilation days.
- The prevalence of multidrug-resistant (MDR) P. aeruginosa in VAP cases is approximately 33% globally.
- MDR infections are associated with 2-3 times higher mortality compared to susceptible infections.
- India's Indian Council of Medical Research (ICMR) tracks AMR trends through the Indian Antimicrobial Resistance Surveillance Network.
