Common Antibiotic Linked to Higher Risk of Death in Major Review

Researchers urge caution after a large analysis found cefepime may be associated with increased mortality in adult patients.

Health News Antibiotics Infectious Diseases Patient Safety

Key Findings: A major review of more than 22,000 patients found that cefepime, a commonly prescribed broad-spectrum antibiotic, was associated with a slightly higher risk of death compared with other β-lactam antibiotics. The increased risk was observed primarily in adults, while no similar increase was seen in children.

What Is Cefepime?

Cefepime is a fourth-generation cephalosporin antibiotic widely used in hospitals to treat serious bacterial infections. It is often prescribed when physicians require broad antibacterial coverage while awaiting laboratory identification of the infecting organism.

What Did Researchers Find?

The systematic review found that patients receiving cefepime experienced a slightly higher overall mortality rate compared with patients treated with other β-lactam antibiotics.

Cefepime Group

11,726 patients

778 deaths recorded

Mortality Rate: 6.6%

Other β-Lactam Antibiotics

Comparison Group

Mortality Rate: 6.2%

Lower observed death rate

Clinical Perspective: Although the difference was relatively small, researchers estimated approximately four additional deaths per 1,000 patients when cefepime was compared with other β-lactam antibiotics.

Adults Appeared More Affected Than Children

A notable finding was the difference between adult and pediatric patients. Adults receiving cefepime showed a higher risk of mortality, while children did not appear to experience increased risk compared with alternative antibiotics.

Adults

The review reported an approximately 18% higher mortality risk among adults treated with cefepime.

Children

Researchers found no evidence that cefepime increased mortality risk among pediatric patients.

Conditions With the Strongest Mortality Signal

The review identified several clinical situations in which cefepime was associated with higher observed mortality.

Febrile Neutropenia

Approximately 19% higher observed mortality risk.

Severe Bacterial Infections

Approximately 19% higher observed mortality risk.

Pneumonia

Approximately 11% higher observed mortality risk.

Meningitis

Approximately 10% higher observed mortality risk.

Urinary Tract Infections

Approximately 33% higher observed mortality risk.

Hospitalized Patients

Researchers recommend further investigation and monitoring.

Experts Urge Careful Interpretation

Infectious disease specialists stress that the findings should be interpreted cautiously. The review included diverse patient populations, different medical conditions, and studies conducted across multiple countries. Therefore, the observed increase in mortality does not necessarily prove that cefepime itself directly causes deaths.

Important: Cefepime remains an important treatment option for severe infections and continues to be used worldwide. Physicians often rely on it when treating critically ill patients who require immediate broad-spectrum antimicrobial coverage.

Should Clinical Practice Change?

Researchers believe the findings should encourage healthcare professionals to carefully consider antibiotic selection, particularly in hospitalized adults. However, experts emphasize that cefepime still has a valuable role in treating complex infections, especially in an era of increasing antimicrobial resistance.

For Healthcare Professionals

Review antibiotic choices carefully.
Balance potential risks and benefits.
Follow antimicrobial stewardship principles.
Monitor patients receiving broad-spectrum therapy.

For Patients

Take antibiotics only when prescribed.
Never stop treatment without medical advice.
Ask about the intended purpose of prescribed antibiotics.
Help reduce antibiotic resistance through responsible use.

The Growing Importance of Antibiotic Stewardship

Healthcare experts warn that antimicrobial resistance continues to increase globally. The responsible use of antibiotics remains essential to preserve the effectiveness of existing treatments. Studies such as this highlight the need for ongoing research to ensure that patients receive the safest and most effective therapies available.

Bottom Line

A large review suggests that cefepime may be associated with a slightly higher risk of death in adults compared with other β-lactam antibiotics. While the findings warrant attention, experts emphasize that cefepime remains an important treatment for serious infections and should continue to be used when clinically appropriate.
