The role of stewardship in fighting drug resistance

Tears rolled down Rakshit’s* cheeks as he talked about losing his 75-year-old father six months ago. In April, his father was rushed to a top hospital after experiencing chest pain. An angiogram showed severe artery blockages, and doctors advised an urgent bypass surgery.

A week after being discharged, his father’s chest wound became infected. He was readmitted to the same hospital and treated with several antibiotics, but the wounds didn’t heal. Lab tests later showed the infection was from a bacteria resistant to most antibiotics, leaving only one or two options. The doctor suggested an expensive treatment plan but warned there were no guarantees.

"The doctor told me everything depended on my father’s response to the medicine," said Rakshit. Already deeply in debt from high-interest loans for his father’s care, Rakshit was conflicted.

Facing mounting hospital bills, Rakshit made the difficult decision to bring his father home against the doctor’s advice. “He passed away two days after we got him home. If I had enough money, I would have agreed to try the expensive medication,” he said.

Rakshit, an air conditioning mechanic, lives with his family of five on Bangalore’s outskirts. His story is not unique. Hospitals nationwide are seeing a rise in critically ill patients being discharged without medical consent, a practice known in medical terms as Discharge Against Medical Advice (DAMA) or Left Against Medical Advice (LAMA).

Experts point to antimicrobial resistance (AMR) as a key driver of this trend.

India is one of the world’s hotspots for antimicrobial resistance, primarily due to the uncontrolled use of antibiotics over the years. The AMR has disproportionately impacted healthcare access for economically and socially vulnerable populations. 

Data collection

Eight years ago, the Indian Council of Medical Research (ICMR) began efforts to collect antimicrobial resistance data from 20 major medical colleges across India. Meanwhile, the National Center for Disease Control (NCDC) collects antimicrobial resistance information from 35 labs across India. A key partner in this initiative is Kasturba Medical College, part of the Manipal Academy of Higher Education (MAHE) in Manipal.

Dr Vandana KE, professor and head of Microbiology at the college and coordinator of the Centre for Antimicrobial Resistance, and Manipal-bioMerieux Centre of Excellence in antimicrobial stewardship, said the soaring medical costs driven by antimicrobial resistance often compel patients' families to opt for discharge against medical advice. Even if they continue to receive hospital care, the health outcome is compromised. “The situation is grave, to say the least,” she said.

The centre of excellence is set up with the support of bioMerieux, a leading French firm focussing on in vitro diagnostics for more than six decades.

The recently released eighth annual antimicrobial resistance report from ICMR has shed light on rising antibiotic resistance and the decreasing effectiveness of standard treatments against common bacteria in India. The report focused on frequently used antibiotics for managing conditions such as upper respiratory infections, fever, diarrhoea, pneumonia, sepsis, community-acquired pneumonia and other bloodstream infections.

Dr Vandana said this data is invaluable for doctors to gauge the resistance levels of specific bacteria. "A few years ago, we had no comprehensive data on antimicrobial resistance. Now, things are slowly but surely improving," she said.

The report, compiled from nearly 10,000 culture-positive isolates across 21 partner hospitals, provides crucial insights. "Each of the partner hospitals collects bacterial samples, analyses their sensitivity patterns, and uploads the information to the national portal," she added.

Limited options

Rising antimicrobial resistance is making many once-common antibiotics less effective. A few decades ago, doctors prescribed antibiotics based on symptoms and physical exams. With the rise of microbiology labs and advanced tests, doctors now send patient samples to labs to identify the specific bacteria and effective antibiotics. This approach helps doctors choose the right treatment, but they’re facing a bigger problem: new antibiotics are scarce, while bacteria are becoming more resistant.

Dr Muralidhar Varma, professor and head of Infectious Diseases at the college and chairman of Antimicrobial Stewardship (AMS) programme, said the number of antibiotics that can be used for treatment has come down drastically. “For example, doctors had seven or eight drugs at their disposal some 25 years ago to treat the common E.coli (Escherichia coli) which causes urinary tract infection,” he said.

“Now, we have only one or two medicines available to treat the same urinary infection. E.coli bacteria has developed resistance to every other antibiotic. This is a huge challenge healthcare professionals are facing now,” he added.

According to experts, antimicrobial stewardship, which encourages the proper and judicious use of antibiotics, is essential in the fight against antimicrobial resistance. The focus is on educating healthcare providers to follow guidelines based on scientific evidence when prescribing and administering antibiotics. 

The Kasturba way

At Kasturba Medical College, a team of pharmacists, physicians, and microbiologists collaborates to ensure that AMS efforts are effective. Under the team’s guidelines, high-end antibiotics can only be administered to patients after receiving approval from the AMS team. “We are not about restricting antibiotic use altogether because patient safety is paramount. If healthcare professionals have a valid reason to prescribe a particular antibiotic, we authorise it,” said Dr Varma. “Similarly, hospital pharmacies must seek AMS team approval before dispensing any new antibiotic.”

We aim to have open conversations with doctors, explaining why certain antibiotics may not be ideal. They understand our reasoning, and we can move forward collaboratively.

The biggest challenge in implementing antimicrobial stewardship is gaining the trust of senior doctors who are accustomed to having autonomy in prescribing antibiotics.

Dr Vandana emphasised that strict mandates are unlikely to work with experienced doctors. “There are two global approaches to stewardship: restrictive and handshake. With a restrictive model, doctors must justify their rationale for using certain antibiotics, but this approach can feel intrusive and harm the programme’s success,” she said.

Dr Vandana’s team primarily relies on the handshake approach. “We aim to have open conversations with doctors, explaining why certain antibiotics may not be ideal. They understand our reasoning, and we can move forward collaboratively,” she said. “The handshake approach fosters shared responsibility.”

Diagnostics is key

“Without proper diagnosis, effective infection management is impossible. That’s why we also focus on diagnostic stewardship. Diagnostic stewardship means applying the right test for the right patient at the right time, along with accurate interpretation and effective communication between the diagnostician and prescriber,” said Dr Vandana. 

However, accurate diagnostics remain a distant dream for much of India’s population, as microbiology labs are scarce or nonexistent in rural areas.

“The lack of access deprives people in these regions of the benefits of both antimicrobial and diagnostic stewardship,” said Dr Varma. “Until we establish robust facilities, a vast majority will be left out of efforts to reduce antimicrobial resistance.”
