Insights

Implementing a urinary tract infection (UTI) panel significantly reduced urine cultures and catheter-associated UTIs (CAUTIs). This positive impact on CAUTI rates persisted even during the COVID-19 pandemic.

Area of Science:

  • Infectious Diseases
  • Healthcare Quality Improvement
  • Epidemiology

Background:

  • Catheter-associated urinary tract infections (CAUTIs) represent a significant healthcare-associated infection burden.
  • Effective strategies are needed to optimize diagnostic approaches and reduce CAUTI incidence, particularly in tertiary care settings.
  • The COVID-19 pandemic introduced challenges to infection control practices and patient management.

Purpose of the Study:

  • To introduce and evaluate the impact of a novel urinary tract infection (UTI) panel on CAUTI rates.
  • To assess the effectiveness of the UTI panel in reducing urine cultures (UC) and CAUTI incidence.
  • To determine if the UTI panel's impact on CAUTI was sustained during the COVID-19 pandemic.

Main Methods:

  • A quasi-experimental design was employed, comparing three periods: pre-panel, post-panel implementation, and post-panel during the COVID-19 pandemic.
  • Data from tertiary care inpatients were analyzed using Poisson regression and interrupted time series (ITS) analysis.
  • Key metrics included catheter days (CD), urine cultures (UC), CAUTI rates per 1,000 CD and patient days (PD), and National Health Safety Network standardized infection ratios (SIRs).

Main Results:

  • Implementation of the UTI panel led to a significant decrease in UC per 1,000 PD (36.9 to 16.6).
  • CAUTI rates per 1,000 CD decreased by 40% post-panel implementation (P < .001).
  • Despite a nonsignificant 13% increase during the COVID-19 period, CAUTI rates remained 32% lower than pre-panel levels (P = .02).

Conclusions:

  • The introduction of the UTI panel was associated with substantial reductions in both UC and CAUTI.
  • The positive impact of the UTI panel on CAUTI reduction was maintained throughout the challenging period of the COVID-19 pandemic.
  • This strategy demonstrates a successful approach to improving UTI diagnostics and infection control in a hospital setting.
