Hospital-acquired Urinary Tract Infections in Patients with Diabetes and Urinary Catheterization

Abstract

Objective Urinary tract infection (UTI) is the most common hospital-acquired infection. Foley catheter-related UTI is associated with increased mortality, morbidity, length of hospital stay, and costs. Few studies have compared the pathogens by bacterial strains, resistance to antibiotics, comorbidities, and related risk factors in hospital-acquired UTI patients with or without diabetes and with or without a Foley catheter. The objective of this study was to compare the variables of hospital-acquired UTI between these two groups. Methods In this retrospective chart review study, we included hospital-acquired UTI patients (hospitalization time > 48 hours) with either diabetes or a Foley catheter from a medical center in Taipei (Taiwan) between January 1, 2011 and December 31, 2012. We excluded patients with positive urine culture for bacteria within 48 hours of admission. Clinically related information was collected using case data sheets. Results We analyzed 595 patients with hospital-acquired UTI; the infection rate of hospital-acquired UTI in our study was significantly higher in patients with a urinary catheter (n = 497) than in those without (p Conclusion Unlike having diabetes, having a urinary catheter was a significant risk factor for hospital-acquired UTI (p
