Abstract:
Risk factors for multidrug-resistant bacteria (MDRB) in nosocomial urinary tract infection (UTI) have been widely studied. However, these risk factors have not been analyzed in community-acquired urinary sepsis (US), nor have its outcomes been studied. The aim of our study is to determine risk factors for MDRB in community-acquired US and its influence on outcomes. Prospective observational study of patients with community-acquired US admitted to a university hospital. We compared epidemiological and clinical variables and outcomes of US due to MDRB and non-MDRB. Independent risk factors for MDRB were analyzed using logistic regression. A total of 193 patients were included, 33.7% of them with US due to MDRB. The median age of patients was 82 years. Hospital mortality was 17.6%, with no difference between the MDRB and non-MDRB groups. The length of hospital stay was 5 (4-8) days, with a non-significant tendency to longer hospital stays in the MDRB group (6 (4-10) vs. 5 (4-8) days, p = 0.051). Healthcare-associated US was found to be an independent risk factor for MDR bacteria by multivariate analysis. In conclusion, the impact of MDR bacteria on the outcomes of community-acquired urinary sepsis was mild. Healthcare-associated US was an independent risk factor for MDR bacteria.
Insights
This study identified healthcare-associated urinary sepsis (US) as a key risk factor for multidrug-resistant bacteria (MDRB) in community-acquired US. While MDRB did not worsen hospital mortality, it showed a trend toward longer hospital stays.
Area of Science:
- Infectious Diseases
- Critical Care Medicine
- Urology
Background:
- Multidrug-resistant bacteria (MDRB) are a growing concern in healthcare settings.
- Risk factors and outcomes for community-acquired urinary sepsis (US) due to MDRB remain understudied.
- Understanding these factors is crucial for effective patient management and infection control.
Purpose of the Study:
- To identify independent risk factors for MDRB in community-acquired US.
- To evaluate the influence of MDRB on patient outcomes, including mortality and length of hospital stay.
- To compare clinical characteristics and outcomes between MDRB and non-MDRB US cases.
Main Methods:
- Prospective observational study involving 193 patients with community-acquired US admitted to a university hospital.
- Comparison of epidemiological and clinical variables and outcomes between patients with MDRB and non-MDRB US.
- Logistic regression analysis to determine independent risk factors for MDRB.
Main Results:
- 33.7% of patients had US caused by MDRB, with a median age of 82 years.
- Hospital mortality was 17.6% and did not differ significantly between MDRB and non-MDRB groups.
- Healthcare-associated US was identified as an independent risk factor for MDRB; a non-significant trend towards longer hospital stays was observed in the MDRB group.
Conclusions:
- The impact of MDRB on outcomes in community-acquired urinary sepsis was found to be mild.
- Healthcare-associated urinary sepsis is a significant independent risk factor for developing MDRB infections.
- Further research may be needed to explore optimal management strategies for MDRB in this patient population.
