Differences in Efficacy between Short- and Long-Course Antibiotic Agents for Joint Prosthesis Infection: A Systematic...

Area of Science:

• Orthopedic Surgery
• Infectious Diseases
• Pharmacology

Background:

• Prosthetic joint infections (PJIs) are a significant complication following joint replacement surgery.
• Optimal antibiotic treatment duration for PJIs remains a subject of clinical debate.

Purpose of the Study:

• To systematically evaluate and compare the failure rates of short-course versus long-course antibiotic therapy for PJIs.
• To determine if extended antibiotic durations offer improved outcomes in PJI management.

Main Methods:

• A comprehensive literature search was conducted across PubMed, Embase, and Cochrane Library databases up to April 2022.
• Meta-analysis of 14 controlled studies (12 observational, 2 RCTs) involving 1,971 participants was performed using Stata 11.0.
• Surgical failure rate post-antibiotic treatment was the primary outcome, with heterogeneity assessed via I² test and meta-regression.

Main Results:

• The meta-analysis revealed no statistically significant difference in surgical failure rates between short-course and long-course antibiotic regimens (RR, 1.08; 95% CI, 0.89-1.32).
• Subgroup analyses confirmed no significant differences across various study areas, treatment modalities, or joint locations.
• Short-term antibiotic therapy (4-6 weeks) demonstrated comparable safety and efficacy to longer durations.

Conclusions:

• Current evidence suggests that patients with PJIs may not necessitate prolonged or lifelong antibiotic therapy post-surgery.
• Short-term antibiotic courses (4-6 weeks) appear to be a safe and effective strategy for managing PJIs.
• These findings support de-escalation of antibiotic duration in PJI treatment protocols.
