Despite being common, healthcare-associated infections are potentially deadly and carry a significant financial cost. Of healthcare associated infections, catheter-associated urinary tract infections (CAUTIs) are one of the most common, despite most instances of CAUTI being preventable.
As CAUTI was determined to be one of the top five influential factors in the publicly reported quality scores, Piedmont Healthcare looked to infection data for more visibility into factors that were contributing to CAUTIs in an effort to permanently reduce the number of infections. By engaging clinical and quality staff for compliance with CAUTI prevention best practices, Piedmont has seen sustainable improvements.
Healthcare-associated infections (HAIs) are a common, costly, and potentially deadly occurrence. Catheter-associated urinary tract infections (CAUTI) are one of the most common HAIs.1
Piedmont Healthcare is an integrated healthcare system of seven hospitals with nearly 100 physician and specialist offices across greater Atlanta and North Georgia. Piedmont looked to the reduction of CAUTIs as an opportunity to improve quality outcomes and reduce costs. Evidence-based practice guidelines are available to inform prevention activities that would lead to a reduction in CAUTIs. However, ensuring compliance with the guidelines is challenging in the complex healthcare environment.2,3,4
Piedmont had attempted efforts to reduce CAUTIs for more than two years. Despite instituting several recommended prevention activities, the health system was unable to make any sustainable gains. As a result, publicly reported quality scores influenced by CAUTI SIR did not portray Piedmont in a favorable light.
Previous prevention activities were focused solely on the outcome measure (CAUTI rate) rather than the factors that impacted infection rates, such as insertion or maintenance of the indwelling urinary catheter. In order to prevent CAUTIs, Piedmont understood it would be necessary to shift focus to monitoring and measuring CAUTI prevention process metrics (insertion and maintenance bundle compliance) and engage providers and nursing staff in the shift in culture. Additionally, the health system knew it needed to move away from the resource-intensive manual chart review they were performing. Thousands of hours were used each year to perform surveillance, hindering improvement efforts by leaving data unavailable in time for care revisions. This also carried with it a significant cost.
Piedmont made CAUTI reduction a top priority. Understanding that clinician ordering practices and care processes contribute to infection risks, the health system established an interdisciplinary CAUTI team with a clear goal of achieving a SIR of less than one through 80 percent compliance with insertion and maintenance bundle components.
Members of the team included urologists, physicians, registered nurses, infection preventionists, quality improvement professionals, and laboratory staff. Physician advisors and nurse champions helped to advocate for change with their peers, and, along with other members of the interdisciplinary team, provided expert guidance for developing policy, decision support algorithms, and care procedures.
To facilitate improvement, Piedmont defined standard work and process metrics for insertion and maintenance of indwelling urinary catheters, and clearly defined the roles and responsibilities for executive leaders, quality leaders, nursing staff, educators, safety coaches, and laboratory staff in preventing CAUTIs.
To ensure easy access to the standard workflow and evidence-based guidelines for indwelling urinary catheters, Piedmont’s interdisciplinary team developed a comprehensive toolkit, referred to as the “promise package.” The toolkit provides frontline staff access to all CAUTI prevention information in one location on the Piedmont intranet. The information includes goals, insertion criteria, policy and procedure links, EHR documentation instructions, and information about the analytics application.
The collaborative efforts resulted in evidence-based guidelines with standard workflow for indwelling urinary catheters, including the following:
Initial improvement efforts focused on prompt discontinuation of indwelling urinary catheters. These efforts did help to decrease the number of CAUTIs slightly; however, to obtain substantial improvement, Piedmont needed insight into the factors contributing to CAUTI. The Piedmont team made the decision to use the Health Catalyst® Analytics Platform, including the Late-Binding™ Data Warehouse and broad suite of analytics applications, implementing the Catheter Associated Urinary Tract Infection (CAUTI) Prevention Advanced Application™ (see Figure 1).
The CAUTI application provides infection prevention specialists, clinical and operational directors, and quality improvements staff easy visualization of various process metrics, supporting the monitoring of catheter days, insertion bundle compliance, and maintenance bundle compliance. Using the analytics application, Piedmont can drill down to the facility, unit, service, or patient level when analyzing performance. This data provides Piedmont the ability to review the effectiveness of quality improvement interventions and provide supporting feedback to nursing staff and providers as appropriate.
The increased visibility of maintenance bundle components (see Figure 2) made it clear that indwelling urinary catheter care was inconsistent across hospital units. Nursing procedures for catheter care varied between units, with some demonstrating effective catheter care and a low number of CAUTIs while others did not.
With better understanding of performance and existing opportunities for improvement, maintenance bundle compliance became the focus of improvement activities.
Nurses are empowered to apply best practice interventions for patients, minimizing the use of urinary catheters and discontinuing indwelling urinary catheters when appropriate. To support nursing staff in managing discussions with providers regarding catheter discontinuation, the comprehensive toolkit includes recommended scripting, and an escalation process should a disagreement arise that cannot not be immediately resolved. Physician advisors provide further support to the nursing staff by delivering education to the nursing staff and sharing changes with physician peers through presentations at medical staff meetings.
It was determined that some CAUTI attributed to the hospital as HAIs at Piedmont were likely inaccurately attributed due to the over-ordering of urinalysis (UA), including some ordering of UA days into the inpatient stay for patients who did not have symptoms of infection. This made it difficult to identify if a patient’s infection was present upon arrival or developed during their hospital stay. To reduce over-ordering of UAs, Piedmont developed standard criteria to diagnose an infection, including when to send the specimen for culture.
Historically, when patients did not empty their bladder for a prolonged period of time, nursing staff would insert a catheter. This was appropriate for some patients, as they were experiencing urinary retention. However, for others the insertion of a catheter increased the risk of infection without benefit to the patient, as their bladders were not full. To ensure that patients at Piedmont were not catheterized more often than necessary, additional bladder scanner equipment was purchased, allowing the nursing staff to assess the volume of urine in the bladder prior to catheterization, decreasing unnecessary catheterization.
By using the standard workflows and evidence-based guidelines for indwelling urinary catheters outlined in the comprehensive toolkit, Piedmont achieved dramatic improvements in less than one year:
“Analytics provided insight into the process metrics rather than outcomes alone, enabling us to reduce the number of CAUTIs through preventive best practices.”– Jeremiah Bame, MBA, BSN, RN

Piedmont continues ongoing monitoring of CAUTI prevention performance. Leaders conduct purposeful rounds, engaging in conversations with nursing providers and answering any questions that staff have, all in an effort to encourage discontinuation of indwelling catheters within 48 hours and to encourage adherence to the standard work and evidence-based practices in the comprehensive toolkit.
