India's antibiotic usage patterns are a cause for concern, according to a recent study published in The Lancet Public Health. The research reveals a complex interplay of over- and under-prescription, highlighting the need for a nuanced approach to antibiotic management in the country.
The study estimates that India ideally requires 14.7 defined daily doses (DID) of antibiotics per 1,000 people per day, with a breakdown of 7.8 DID of 'access' antibiotics, 6 DID of 'watch' antibiotics, and 0.99 DID of 'reserve' antibiotics. However, the actual consumption data paints a different picture. India currently uses 18.3 DID overall, with a significant imbalance in the distribution of antibiotic types.
One of the key findings is the overuse of 'watch' antibiotics, which are broad-spectrum drugs reserved for specific infections when simpler alternatives are ineffective. This overuse suggests that some patients are being unnecessarily exposed to these powerful antibiotics, potentially contributing to the development of antimicrobial resistance. The study also highlights the underuse of 'access' antibiotics, which are first-choice drugs for common infections, and 'reserve' antibiotics, which are last-resort treatments for multidrug-resistant infections.
This imbalance in antibiotic usage has broader implications. High-income countries currently consume the most 'watch' and 'reserve' antibiotics, but the study reveals that the majority of the world's need for these medicines lies in lower-income countries, where infectious disease burdens are highest. This disparity underscores the global challenge of ensuring equitable access to appropriate antibiotics while addressing overuse in some regions.
The study's findings are not isolated to India. The National Centre for Disease Control's survey in 2021-22 revealed similar patterns, with nearly three-quarters of hospitalised patients receiving antibiotics, and a significant proportion prescribed 'watch' antibiotics. This data further emphasizes the need for improved antibiotic stewardship and awareness in India.
The implications of these findings are far-reaching. Overuse of 'watch' antibiotics can lead to the development of resistant bacteria, compromising the effectiveness of these drugs in the future. Underuse of 'access' and 'reserve' antibiotics can leave patients with drug-resistant infections without adequate treatment options. Addressing these imbalances is crucial for preserving the efficacy of antibiotics and ensuring patient outcomes.
The study's authors, including Prof. Ramanan Laxminarayan, stress the importance of ensuring populations have access to the right antibiotics at the right time while reducing unnecessary use. This requires a multi-faceted approach, including improved antibiotic stewardship, awareness campaigns, and policy interventions to balance the use of 'access', 'watch', and 'reserve' antibiotics.
In conclusion, India's antibiotic usage patterns, as revealed by the Lancet study, highlight a complex interplay of over- and under-prescription. Addressing these imbalances is essential for preserving antibiotic efficacy, ensuring patient outcomes, and tackling the global challenge of antimicrobial resistance.
