Abstract

Insights

For methicillin-susceptible S. aureus (MSSA) prosthetic joint infections (PJI), not following IDSA surgical guidelines increases the risk of treatment failure. Complete implant removal is recommended when implant retention is not feasible.

Area of Science:

  • Orthopedic Surgery
  • Infectious Diseases
  • Clinical Research

Background:

  • Prosthetic joint infection (PJI) management requires adherence to established guidelines.
  • The long-term outcomes of methicillin-susceptible S. aureus (MSSA) PJI treatment based on IDSA guidelines are not fully understood.

Purpose of the Study:

  • To evaluate the impact of adherence to IDSA surgical guidelines on treatment success in MSSA PJI.
  • To identify risk factors for treatment failure in patients with MSSA PJI.

Main Methods:

  • Retrospective cohort study of 89 patients with MSSA hip or knee PJI (2000-2010).
  • Univariate Cox analysis was used to assess the association between non-compliance with IDSA surgical guidelines and treatment failure.

Main Results:

  • Non-compliance with IDSA surgical guidelines was significantly associated with treatment failure (HR 2.157).
  • Mean follow-up was 2.8 years.
  • American Society of Anesthesiologists score, inadequate antimicrobial therapy, and rifampicin-based regimens did not significantly impact outcomes.

Conclusions:

  • Adherence to IDSA surgical guidelines is crucial for successful MSSA PJI treatment.
  • Complete implant removal is recommended for MSSA PJI cases where implant retention is not possible to prevent treatment failure.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Urine Studies II: Urine Culture and Sensitivity Test

A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
