Framework
Learning Outcomes
To describe the epidemiology of CAUTI To overview the SSHAIP CAUTI surveillance programme To apply the data definitions for CAUTI correctly To evaluate the data collection processes available To maximise the potential for reduction of HAI through surveillance activities
Background to CAUTI surveillance What is the problem?
Most common infection in acute hospitals and long-term care facilities
2.5% of hospital patients acquire a UTI
Length of hospitalisation (average 5-6 days)
(Plowman et al, 1999)
Cost to the patient
• Pain and discomfort • Complicated upper urinary tract infection • Bacteraemias

Background to CAUTI surveillance Risk Factors
Major predisposing factor
• indwelling urinary catheter
• average of 26% of hospitalised patients are catheterised (Glynn et al, 1997)
• risk of CAUTI is 1-2% per procedure
Risk ↑ for each additional day of catheterisation
Common in long-term catheterised patients
Associated Risk Factors
A history of previous catheter use Duration the catheter is in situ Length of stay in hospital prior to catheter insertion
Location of catheter insertion
SSHAIP CAUTI SURVEILLANCE PROGRAMME
Surveillance ……….
“Surveillance is the ongoing systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice, closely integrated with the timely dissemination of these data to those who need to know. The final link of the surveillance chain is the application of these data to prevention and control”.
(Centers for Disease Control and Prevention 1988)
Why CAUTI surveillance?
The HAI Task Force have prioritised urinary catheterisation
Best Practice Statement
Prepared by NHS Quality Improvement Scotland
CAUTI Surveillance
Carried out by SCIEH
Aims of CAUTI Surveillance
Collect surveillance data and describe trends in catheter use and CAUTI Evaluate the impact of Best Practice in terms of:
• patient practice • infection rates
Assist hospitals in of CAUTI
Essential elements of a successful HAI surveillance system
Defining what outcomes to measure Ensuring everyone involved is aware of the outcomes Reliably collecting the data in a standardised/defined manner Analysing data for comparison Using the data locally in a timely manner to improve quality of care
Gaynes and Solomon. J Quality Improvement (1996) 22:457-67
Patient Population
17 specialties have been chosen for CAUTI surveillance
Each participating hospital will chose ONE of the listed specialties for surveillance Specialities represent:
Medicine Surgery Gynaecology & Obstetrics Primary care
Paediatrics are included
Who is included?
Patients with a urinary catheter inserted in the • chosen specialty • emergency room • theatre
Who is excluded?
Patients are excluded if:
•
The indwelling urethral catheter was inserted before the start of the UTI surveillance period Catheter is in situ on admission to the hospital (e.g. from the community or transferred from another hospital).
•
Exclusions cntd………
Patients are excluded if:
•
The indwelling catheter is inserted in a specialty out with the chosen specialty (with the exception of the operating theatre and emergency department)
•
They are nursed on wards not allocated to that specialty
They are not from the chosen specialty but are nursed in a ward designated to the chosen specialty
•
Exclusions cntd……………
Patients are excluded if:
• •
They have a single in-and-out catheter The indwelling catheter has been in place for less than 6 hours The catheterisation is intermittent (i.e.
•
insertion and removal of a catheter into the bladder every 3-6 hours for the drainage of urine)
•
They have suprapubic catheterisation
Exclusions cntd……………
Patients are excluded if:
•
They are undergoing treatment for a UTI when the catheter is inserted
•
They are nursed on an ICU/HDU associated with the specialty, unless the patient population has been defined to include these wards when the surveillance started
Patient Pathways for CAUTI surveillance
Admission to chosen specialty
Catheter inserted in
theatre or A&E
Catheter Inserted
Admission to chosen specialty
Catheter removed 3-day follow-up
UTI
Catheter in-situ to day 30
Discharge
Transfer
Death
End of Surveillance
Data collection methods
Electronic data collection on Tablet PC or laptop
An electronic data collection tool for CAUTI surveillance has been developed
Paper data collection
Paper forms sent to SCIEH for scanning and entry to database OR Data entered to database at local level
Data collection methods
Data
collection- Who? Designated data collector
e.g. ICN; surveillance nurse; member of ICT or trained ward staff
Data transferred by data collector or data manager/IT staff
Data collection- What?
What data?
Admission data • Total no. of admissions to chosen specialty in the surveillance period • Total number of patient days Catheter use • Total number of catheter days
Infection details • onset date/symptoms and signs/causative organism and risk factors
Data collection- How?
Admission data –System of your choice • Medical Records • Ward Admission worksheet

Data collection- How?
Catheter use (identify patients eligible for surveillance)
Daily
• Visit wards and identify catheterised patients from nursing records, medical records and ward staff
CAUTI details
Daily
• Check urine microbiology reports for specialty under surveillance
• Review medical and nursing records temperature and treatment charts
CAUTI DATA DEFINITIONS
CAUTI Data Definitions
A healthcare associated UTI considered to be catheter associated if:
An indwelling catheter is in situ at time of onset of UTI (Criterion 1)
OR
An indwelling catheter was removed within 3 days prior to the onset of UTI (Criterion 2)
AND
The first positive urine specimen is taken or the physician makes a diagnosis more than 48 hours after the catheter was inserted
CAUTI Data Definitions
CAUTI Criterion 1 Definition
For patient’s with an indwelling catheter
in situ
AND ≥104 micro-organisms per ml from a catheter specimen of urine AND
CAUTI Data Definitions
CAUTI Criterion 1 cntd….
ONE or more of the following with no other recognised cause: Loin Pain Loin or suprapubic tenderness Fever (≥38oC skin temp) Pyuria (≥104WBC per ml)

CAUTI Criterion 1 cntd….
OR…..
The physician diagnoses UTI, institutes antibiotic therapy
AND
CAUTI Data Definitions
CAUTI Criterion 1 cntd….
The patient has TWO or more of the following with no other recognised cause: Loin Pain Loin or suprapubic tenderness Fever (≥380C skin temp) Pyuria (≥104WBC per ml)
CAUTI Data Definitions
CAUTI Criterion 2 Definition
For patient’s who had catheter removal within 3 days before the onset of CAUTI AND ≥ 105 micro-organisms from a mid stream specimen AND
CAUTI Data Definitions
CAUTI Criterion 2 cntd….
ONE or more of the following with no other recognised cause:
Urgency Frequency Dysuria Loin Pain Loin or suprapubic tenderness Fever (≥ 38oC skin temp) Pyuria (≥ 104WBC per ml)
CAUTI Data Definitions
CAUTI Criterion 2 cntd…. OR……..
The physician diagnoses UTI, institutes antibiotic therapy

The patient has TWO or more of the following with no other recognised cause:
Urgency Frequency Dysuria Loin Pain Loin or suprapubic tenderness Fever (≥ 38oC skin temp) Pyuria (≥ 104WBC per ml)
CAUTI Definitions
• CAUTI must meet one of the criteria 1 or 2
as described
• Patients with asymptomatic
bacteriuria/bacteria in their urine are NOT considered to have a CAUTI
Definitions state that quantitative bacterial counts should be recorded.
“Light, Medium or Heavy Growth” may be recorded if these terms are defined to SSHAIP prior to starting surveillance.
In conclusion
What am I looking for?
Does the patient have an indwelling catheter?
Does the patient have a CAUTI?
– Are there defined signs and symptoms?
What is the infection onset date?
– Signs and symptoms should be recorded on form
when first noticed
