Analysis of Prosthetic Joint Infections Following Invasive Dental Procedures in England.

Area of Science:

• Orthopedics and Dental Medicine
• Infectious Disease Epidemiology
• Public Health Policy

Background:

• Patients with prosthetic joints often receive antibiotic prophylaxis before invasive dental procedures (IDP) to prevent late prosthetic joint infection (LPJI).
• This practice is common despite a lack of robust evidence supporting its efficacy or demonstrating a causal link between IDP and LPJI.
• Concerns also exist regarding antibiotic resistance, adverse drug reactions, and healthcare costs.

Purpose of the Study:

• To investigate the temporal association between invasive dental procedures (IDP) and subsequent late prosthetic joint infection (LPJI).
• To provide evidence-based guidance on the necessity of antibiotic prophylaxis for patients with prosthetic joints undergoing dental work.

Main Methods:

• A large-scale cohort study utilizing a case-crossover and time trend design was conducted in England.
• Data from 9427 hospital admissions for LPJI between 2011 and 2017 were analyzed, with a focus on dental records.
• The incidence of IDP in the 3 months preceding LPJI admission was compared to the 12 months prior, in a setting where antibiotic prophylaxis for LPJI prevention is not standard practice.

Main Results:

• No significant temporal association was found between invasive dental procedures and late prosthetic joint infection.
• The incidence of IDP was actually lower in the 3 months immediately preceding LPJI hospital admission (IRR, 0.89; 95% CI, 0.82-0.96).
• These findings challenge the established clinical practice of routine antibiotic prophylaxis.

Conclusions:

• The study provides no evidence to support the routine administration of antibiotic prophylaxis before invasive dental procedures in patients with prosthetic joints.
• Current practices may not be effective in preventing late prosthetic joint infections and could contribute to antibiotic resistance.
• Clinical guidelines should be re-evaluated based on this evidence to optimize patient care and antimicrobial stewardship.
