Indwelling Urinary Catheters: Prevention of catheter-associated urinary tract infections (CautiS)

Presented By:April Beresford, Benjamin Kasper, and Kara Elkins

ProblemCatheter associated urinary tract infections (CAUTI) are the cause of many hospital acquired infections.

Nearly 25% of hospitalized patients are catheterized annually, and 10% of these patients develop infections (Oman et al. 2011, p. 1).

40% of all nosocomial infections are due to CAUTIs (Andreessen et al., 2012, p. 209).

ProblemPatients have increased pain and discomfort due to CAUTIs.

CAUTIs are an unnecessary added expense to healthcare costs.

EvidenceArticle One

Preventing Catheter-Associated Urinary Tract Infections in Acute Care

Conducted by Andreessen et al.

Development of bundle plan to assist nurses in insertion techniques and maintenance or urinary catheters

Daily assessment of need by nurse and physician

Requirement of orders q24 hours to continue catheter use

Changing practice and adding

meticulous computer

documentation

Reducing

use and duration of

catheters

Percentage of CAUTIs experienced by patients should decrease

EVIDENCEArticle One – Literature Review

The “bundle” that they created to decrease percentage of CAUTI was put together based on the information gathered in the review of literature“

The strongest predictor for CAUTI is the duration of catheterization, and catheterization lasting more than six days increases the risk for CAUTI seven times” (Andreessen et al. 2012, p. 210).

EVIDENCEArticle One – Hypothesis

Dependent variable: duration of urinary catheterizationIndependent variables: urinary catheter bundle, which included proper insertion and assessment techniques to be utilized, computerized documentation, and ordering templates

.

The population

defined in

this case is “acutely hospitalized patients” (Andreessen et al., 2012, p. 211).The study was performed using an experimental pretest and posttest design.Andreessen et al.

performed an

evaluation before and after the introduction of the urinary catheter bundle.

EVIDENCEArticle One – Data Collection

Evaluation of 1,200 charts to collect baseline data over three weeksMonths of collecting data after the urinary catheter bundle and other policies were put into

place

Ended

with another three-week post program evaluation

and review of 1,385 computerized medical charts to collect the outcome data (Andreessen et al., 2012, p. 211).Documentation review was performed by registered nurses, physicians, and infection control nurses, along with the other members of the research team (Andreessen et al., 2012, p. 211).

EVIDENCEArticle One – Sample

“The research project took place at a VA (veterans affairs) medical center, and included patients with acute placement (less than thirty days) of an indwelling urinary catheter” (Andreessen et al., 2012, p. 211).Only

male patients were included

due to patient majority being male at this VA facility.

EVIDENCEArticle One – Sample

All charts were reviewed for those male, and eighteen and older (Andreessen et al., 2012, p. 211).Patients

who needed long-term catheterization, or were diagnosed with a urinary tract infection within 24 hours of admission were excluded from the study to protect from misinformation in the data collected (Andreessen et al., 2012, p. 211).

EVIDENCEArticle One – Limitations

Conducted at a single site which causes limitation in the results

“The project also lacked CAUTI rates for comparison because the hospital had not collected this rate before this project began” (Andreessen et al., 2012, p. 211).

EVIDENCEArticle One – Conclusion

It was discovered at the end of the study that “the implementation of a set of guidelines (the urinary catheter bundle) for catheter use and care resulted in a reduction of catheter use by 57% and a significant decrease in catheter duration by 70%” (Andreessen et al., 2012, p. 216).

EVIDENCEArticle Two

Nurse-directed interventions to reduce catheter-associated urinary tract infections

Conducted by Oman et al.

Oman

et al directed a study at the University of Colorado in 2011 to evaluate the effectiveness of nursing interventions at avoiding CAUTI

.

“Catheters may be inappropriately retained for days because of convenience, misunderstanding of their necessity, or lack of clear orders for removal. Therefore, efforts to reduce CAUTI prevalence must focus on evidence-based use of IUCs during insertion, maintenance and removal” (Oman et al, 2011, p. 1

).

EVIDENCEArticle Two – Purpose / Framework

Oman et al used a pre/post quasi-experimental design to test incidence rates of CAUTI in a pulmonary and a general medical surgical unit at a Colorado hospital, using nurses as champions of change. Dependent variables: incidence rates of CAUTI, catheter duration, LOS, bladder scanner usage, and product streamlining

.

Independent variables: solidified as “nursing interventions” but was broken down into a series of interventional options presented to nurses who were participating in the study

(Oman et al, 2011, p. 2-3)

EVIDENCEArticle Two – Framework / Data Collection

Study was divided into three phasesPHASE ONE: baseline data on IUC duration and CAUTI rates was obtained

PHASE TWO: intervention begins hospital-wide, including new protocols, updated training for staff, and product evaluation was performed

.

PHASE THREE: interventions targeted the targeted units, including: more education and journal review with staff nurses, purchase of 2 new bladder scanners and additional bedside commodes, charge nurse catheter rounds, and posting of flyers throughout the department outlining facets of evidence based best practice techniques and interventions

.

(Oman et al, 2011, p. 2-3)

EVIDENCEArticle Two – Framework / Data Collection

Electronic patient records were used to identify patients with CAUTI and to determine the length of catheterizations. CAUTIs were reported as an absolute number and a number of infections per 1,000 catheter-days for eligible patients.

(Oman et al, 2011, p. 2-3)

EVIDENCEArticle Two – Results

It was found that nursing based interventions did result in a decrease of CAUTI within the designated units, although it was beyond the scope of the study to determine which interventions were most and least effective.

“This project suggests that a focused unit intervention may be indicated when there is inadequate response to hospital-wide strategies” (Oman et al, 2011, p. 5

)

EVIDENCEArticle Three

Reducing use of indwelling catheters and associated urinary tract infections

Conducted by

Eplern

et al.

CAUTIs remain an ongoing battle

Guidelines for indwelling catheter use can reduce CAUTIs (

Elpern

et al. 2009).

Quality improvement indicators determine CAUTI rates

EVIDENCEArticle Three – Purpose/Framework

Intervention theory which consisted of the followingRemoval of inappropriate catheters Assessment for need for cathetersEarly removal of indwelling catheters

“This study was a before-and-after evaluation of a low-technology intervention to reduce duration of urinary catheterization and occurrence of CAUTIs in an MICU” (

Elpern

et al. 2009 p. 537).

EVIDENCEArticle Three – Data Collection

Subjects included in this study consisted of all MICU patients during a six month periodData collected during intervention phaseDuration of catheterization

Appropriateness of catheterization

Reasons for inappropriate catheter use

CAUTI rates based upon surveillance by nurse epidemiologists

Elpern et al. (2009)

EVIDENCEArticle Three – Findings

Pre – Post intervention data analysis showed a decrease in catheter useEleven months previous to intervention, 15 CAUTIs occurred during 3,429 device daysDuring the intervention phase, zero CAUTIs occurred in 1,432 device days.

Implications for practice / recommendationsUrinary catheterization is necessary in many patient situations

Overuse has been demonstrated to be a significant contributor to increased infection ratesQuestioning attitudes about catheter use assist in CAUTI reductionDaily reassessment for catheter needCatheter use based on patient need not nurse preference

Education for proper catheter care

Development of practice policies
