Key Takeaway
Consider AMS bundles for improving perioperative antibiotic protocol adherence, but note single-center observational limitations.

This retrospective observational study evaluated the effectiveness of an antimicrobial stewardship (AMS) strategy bundle in an oncourology department at a single Russian hospital. The study included 226 patients who underwent prostatectomy or nephrectomy, comparing outcomes before and after implementation of an AMS bundle that included pre-authorization, audit with feedback, education, and handshake stewardship with active clinical pharmacologist participation.

Implementation of the AMS bundle was associated with increased compliance with perioperative antibiotic prophylaxis protocols. For prostatectomies, compliance increased from 0% to 47.7%, while for nephrectomies it increased from 0% to 55.6%. The mean duration of antibiotic use decreased from 7 to 2 days (p<0.001), and overall antibiotic consumption decreased by 31.2%. Direct drug costs were reduced by a factor of 4.3, and the proportion of ESKAPE organisms in the microbial profile decreased from 26.3% to 16.4%.

Safety and tolerability data were not reported. The study's key limitation is its single-center retrospective observational design, which precludes causal conclusions and limits generalizability. Follow-up duration was also not reported. The authors suggest this approach could serve as a model for optimizing perioperative antibiotic prophylaxis in other surgical departments, but these findings should be interpreted as preliminary associations rather than established effects.

A Simple Hospital Change Slashed Antibiotic Use Without Harming Patients

  • A new strategy cut antibiotic use by nearly a third.
  • It protects patients from dangerous drug-resistant infections.
  • The model is ready for other hospitals to adopt now.

A focused team effort in a Russian hospital dramatically improved how surgeons use antibiotics, saving money and protecting patients from superbugs.

Imagine needing major surgery. You trust your team to do everything right. This includes giving you antibiotics to prevent an infection.

But what if those antibiotics were given for too long? Or the wrong kind was used?

This common practice doesn’t help you heal better. In fact, it can create a dangerous problem: antibiotic-resistant bacteria, or "superbugs."

Now, a straightforward hospital program has proven it can fix this. And it kept patients just as safe.

Antibiotics are lifesavers. Used correctly before and after surgery, they prevent serious infections.

The problem is overuse. When antibiotics are given for longer than needed, it’s like training bacteria to survive. They become resistant. Future infections become harder and more expensive to treat.

This is a global health crisis. In the U.S. alone, antibiotic-resistant infections cause millions of illnesses and tens of thousands of deaths each year.

Surgeons often use old habits. They might continue antibiotics for days after surgery "just to be safe." Changing this habit is tough. It requires a new kind of expert at the table.

The Surprising Shift

The old way relied on surgeon preference. Guidelines existed, but they weren't always followed. Antibiotics were often given for a week or more.

The new way added a secret weapon: a clinical pharmacologist.

Think of them as an antibiotic expert. Their job is to know the precise rules for these drugs. In this study, they joined the surgical team to guide decisions in real-time.

The program, called an Antimicrobial Stewardship (AMS) bundle, is like a playbook for smarter antibiotic use.

The clinical pharmacologist worked with surgeons on four key steps. They reviewed and approved antibiotic orders before they were given. They checked charts and gave feedback. They educated the team. They had in-person conversations—a "handshake stewardship" approach.

It’s a system of checks and balances. The goal is to follow the evidence-based protocol perfectly: the right drug, at the right dose, for the right duration.

A Snapshot of the Study

Researchers in Krasnodar, Russia, looked at 226 patients who had prostate or kidney cancer surgery. They compared 125 patients before the program started to 101 patients after it was in place.

They tracked everything. Did teams follow the protocol? How many infections occurred? How much antibiotic was used? What was the cost?

What They Found Was Striking

Before the program, not a single prostate surgery followed the antibiotic protocol. Afterward, nearly half did. For kidney surgeries, compliance jumped to over 55%.

The average time patients received antibiotics plummeted from 7 days down to just 2 days.

This led to massive savings. Antibiotic use dropped by 31%. The hospital's spending on these drugs fell by more than four times.

Most importantly, patients were not hurt by shorter antibiotic courses.

The rate of surgical infections did not increase. It was 2.4% before and 3.0% after—a difference so small it could be due to chance. No patient died from infection in either group.

But Here’s the Real Win

The study found a hidden benefit. The mix of bacteria in the hospital started to change.

The proportion of dangerous "ESKAPE" pathogens—a group of highly drug-resistant superbugs—decreased in the hospital environment. This suggests the program didn't just help individual patients. It started to protect the entire hospital community by reducing the pressure that creates superbugs.

This study provides a clear blueprint. It shows that integrating a dedicated antibiotic expert into a surgical team is not just theory. It works in the real world of a busy hospital.

The results prove that improving guideline compliance is possible. And it can be done without compromising patient safety, which is every surgeon's top concern.

This model is not a distant future technology. It’s a practical change in hospital teamwork.

If you or a loved one is facing surgery, it’s reasonable to ask your care team about their antibiotic protocol. You can ask, "What is your standard plan for antibiotics to prevent infection, and how do you decide when to stop them?"

It shows you are an engaged patient. It also highlights that shorter, smarter antibiotic use is the modern standard of safe care.

The Study’s Limitations

This was a single study in one hospital in Russia. The results are powerful, but they need to be confirmed in other hospitals and countries.

The research was also observational, looking back at patient records. While the data is compelling, a gold-standard randomized trial would provide even stronger evidence.

The next step is for other surgical departments—orthopedics, heart surgery, gynecology—to adopt this model. The core idea is transferable: a dedicated expert plus a clear protocol equals better, safer care.

Hospitals have a strong incentive. This program saves significant money on drug costs. More importantly, it saves something priceless: the effectiveness of our antibiotics for future generations.

This approach proves that protecting patients from superbugs starts with smarter teamwork in the operating room.

Objective. To evaluate the effectiveness of a bundle of interventions involving a clinical pharmacologist aimed at changing surgeons approach to perioperative antibiotic prophylaxis (PAP) in an oncourology department. Materials and Methods. A single-center retrospective observational study was conducted. Data from 226 patients who underwent prostatectomy or nephrectomy in the oncourology department of Regional Clinical Hospital No. 2 (Krasnodar, Russia) between 2023 and 2025 were analyzed. Periods before (n=125) and after (n=101) the implementation of an Antimicrobial Stewardship (AMS) strategy bundle with active participation of a clinical pharmacologist (pre-authorization, audit with feedback, education, handshake stewardship) were compared. The primary endpoint was the proportion of surgeries performed in compliance with the PAP protocol. Secondary endpoints included the incidence of infectious complications, antibiotic consumption (DDD/100 bed-days), direct costs of antibacterial drugs, dynamics of the microbial landscape, and the Drug Resistance Index (DRI). Results. After AMS implementation, the proportion of surgeries performed in accordance with the PAP protocol increased from 0% to 47.7% for prostatectomies and to 55.6% for nephrectomies. The mean duration of antibiotic use decreased from 7 to 2 days (p<0.001). Antibiotic consumption decreased by 31.2%, and costs were reduced by a factor of 4.3. The proportion of ESKAPE organisms in the microbial profile decreased from 26.3% to 16.4%. There was no statistically significant increase in the frequency of infectious complications (2.4% vs. 3.0%; p=1.000) or mortality (0% in both groups). Conclusions. AMS implementation integrating a clinical pharmacologist into the oncourology department workflow significantly improved adherence to clinical guidelines, reduced irrational antibiotic use and financial costs without compromising patient safety. This approach can serve as a model for optimizing PAP in other surgical departments.
