Urinary Tract Infections and
Catheter-Associated Urinary Tract Infections
A urinary tract infection (UTI) is an infection of the bladder, kidneys, ureters, or urethra that occurs when bacteria enter the urinary system. As a result of the infection, a person’s urine, which is normally sterile, will contain bacteria. This type of infection occurs more often in females versus males, due to the anatomy of the bladder and urethra.
A urinary catheter is a thin tube placed in the bladder to drain urine. Urine drains through the tube into a bag that collects the urine. Catheter-associated urinary tract infections (CAUTIs) are infections caused by bacteria that have entered the urinary tract during the catheter's insertion, through the catheter tube, or through the catheter’s external surface.
Common symptoms of UTIs may include burning during urination, burning and pain in the lower abdomen, fever, and cloudy or bloody urine. In some cases, a person may have a CAUTI and not experience any symptoms.
Some patients may be at higher risk for developing a UTI due to older age, poor hygiene, or poor hydration (not drinking enough fluids). Female sex, older age, method of catheterization, duration of catheterization, and quality of catheter care are risk factors for CAUTI. (citation) It is important that both the patient and the healthcare providers take the appropriate steps to help prevent an infection.
Estimated burden of CAUTIs in healthcare facilities in the United States:
- UTIs are the fourth most common type of HAI in the United States (citation)
- 13% of HAIs reported, comprising an estimated 93,300 infections annually.
- Approximately two-thirds (68%) of UTIs in acute care hospital settings are estimated to be catheter-associated.
- According to the 2012 CDC National and State HAI Progress Report, in 2012, an estimated 54,500 catheter-associated urinary tract infections occurred in hospital critical care units and inpatient wards.
- CAUTIs lead to longer length of hospital stay.
- CAUTI is the leading cause of secondary bloodstream infection.
- Using antibiotics to treat UTIs without symptoms contributes to antibiotic resistance and can lead to the development of Clostridium difficile infection
- Urinary catheters and UTIs
- An estimated 15-25% of hospitalized patients will have a urinary catheter at some time during their hospital stay. (citation)
- Catheter use is less common in long-term care facilities (~5%). (citation)
- Studies have found a strong correlation between catheter use greater than six days and the development of a CAUTI. (citation)
- An estimated 13,000 deaths (mortality rate 2.3%) are attributed to UTIs annually in the United States. (citation)
- The mortality rate increases to approximately 10% when the patient also has a secondary bacteremia (bloodstream infection as a result of the UTI). (citation)
- Costs (citation)
- Estimated cost per infection ranges from $750-$1,000
- Estimated total cost in the United States ranges from $340 million - $450 million annually

In January 2012, the Centers for Medicare and Medicaid Services (CMS) will begin requiring acute care hospitals participating in their Inpatient Prospective Payment System (IPPS) to report CAUTIs in adult and pediatric intensive care units. In October 2012, CMS will also begin requiring reporting of CAUTIs in inpatient rehabilitation facilities. These data will be made publicly available on Hospital Compare.
VDH HAI Program activities to address CAUTIs and UTIs:
- UTI prevention collaborative (June 2011 – November 2011): Twelve nursing homes in the Eastern region participated in this project that focused on sharing strategies for effective prevention, treatment, and surveillance of UTIs and CAUTIs. Implemented by VDH in partnership with the Virginia Health Care Association (VHCA). Piloted surveillance using a form developed by VDH and the collaborative participants. Gerontology and infectious disease experts from the Eastern Virginia Medical School (EVMS) engaged to provide education to collaborative facility staff and local physicians.
- March 21, 2012: How to Use the Successful Strategies for the Prevention of Urinary Tract Infections in Long-Term Care Toolkit (webinar slides)
- In this one-hour webinar, Carol Jamerson (Nurse Epidemiologist, VDH) provided an overview of each of the documents in the UTI toolkit and how they may be used in long-term care facilities. Adriana Agnew (Director of Quality Management/Infection Preventionist, Fairfax Nursing Center) described how her facility has used and plans to use the tools to enhance current policies and practices.

Prevention Strategies for Healthcare Providers
To prevent CAUTIs, doctors, nurses, and other healthcare providers should follow CDC infection prevention guidelines including:
- Insert catheters only for appropriate indications.
- Remove the catheter as soon as it is no longer needed. The sooner a catheter is removed, the less likely the chance of infection.
- Ensure that only properly trained persons insert and maintain catheters.
- Insert catheters using aseptic technique and sterile equipment (acute care setting).
- Properly secure catheters after insertion to prevent movement.
- Following aseptic insertion, maintain a closed drainage system.
- Maintain unobstructed urine flow.
- Keep catheter and collecting tube free from kinking.
- Keep collecting bag below level of bladder at all times.
- Empty collecting bag regularly using a separate, clean container for each patient.
- Comply with CDC hand hygiene recommendations and Standard Precautions

Successful Strategies for the Prevention of Urinary Tract Infections in Long-Term Care TOOLKIT (Fall 2011)
This urinary tract infections (UTI) toolkit contains infection prevention presentations, resources, and tools that have been adapted for long-term care facilities (LTCFs). The toolkit was developed as a result of a collaborative effort between 12 nursing homes in the Eastern region of Virginia, the Virginia Department of Health (VDH) Healthcare-Associated Infections (HAI) Program, and the Virginia Health Care Association (VHCA) to impart best practices in the prevention of UTIs within the long-term care (LTC) population.
These documents have been developed from published literature reviews, evidence-based research, standards of practice, or recommendations obtained from the Centers for Disease Control and Prevention (CDC), Healthcare Infection Control Practices Advisory Committee (HICPAC), Centers for Medicare and Medicaid Services (CMS), licensing agencies, professional organizations, or other recognized sources. Materials and information from other organizations in this toolkit that use hospital-centered language also apply to LTC settings.
UTIs are very common in residents in long-term care facilities and consequently result in a significant amount of antimicrobial use within the resident population. It is our hope that the toolkit will be used to support best practices for the prevention of urinary tract infections and promote strategies to improve resident care including the judicious use of antimicrobials.
The toolkit is meant to introduce and summarize guidelines and best practices, and does not replace published standards and regulations. Refer to the toolkit component, “UTI Prevention Resources and References”, to help access the official guidelines and regulations and contact the VDH HAI Program with questions.
We would appreciate any feedback on the materials including which resources are most helpful and which have areas for improvement. Please check our website periodically for updates on toolkit materials.
