Abstract:
We have investigated prospectively the incidence of urinary tract infection (UTI) in 5320 orthopaedic patients. There were 74 UTIs (1.39%). Enterobacteriaceae was the most frequent etiological agent. Each infection increased the length of stay in hospital by more than 8 days. Statistically independent risk factors for the development of urinary infection were a preoperative stay of more than 4 days, inadequate preoperative preventive measures, central venous catheterization and urinary catheterization. Sex, age, or type of surgery had no statistical influence on the development of infection.
Insights
Urinary tract infections (UTIs) occurred in 1.39% of 5320 orthopaedic patients, increasing hospital stays. Key risk factors included prolonged preoperative stays and catheterization.
Area of Science:
- Orthopaedic surgery
- Infectious disease epidemiology
- Healthcare-associated infections
Background:
- Urinary tract infections (UTIs) are common healthcare-associated infections.
- Orthopaedic patients represent a significant population at risk for UTIs.
- Understanding UTI incidence and risk factors is crucial for patient care and resource management.
Purpose of the Study:
- To prospectively investigate the incidence of UTIs in a large cohort of orthopaedic patients.
- To identify the primary etiological agents responsible for UTIs in this population.
- To determine independent risk factors associated with UTI development in orthopaedic surgical patients.
Main Methods:
- Prospective investigation of 5320 orthopaedic patients.
- Data collection on UTI incidence, causative agents, and patient characteristics.
- Statistical analysis to identify independent risk factors for UTI development.
Main Results:
- A UTI incidence of 1.39% (74 cases) was observed.
- Enterobacteriaceae was the most frequent etiological agent.
- Each UTI episode prolonged hospital stay by over 8 days.
- Independent risk factors included prolonged preoperative stay (>4 days), inadequate preventive measures, and both central venous and urinary catheterization.
- No statistically significant influence of sex, age, or surgery type on UTI development was found.
Conclusions:
- UTIs represent a significant complication in orthopaedic surgery, impacting patient outcomes and hospital length of stay.
- Prolonged preoperative stays and the use of catheters are key modifiable risk factors.
- Targeted preventive strategies focusing on these risk factors are essential to reduce UTI incidence in orthopaedic patients.
