ObjectivesAfter this session, the attendee should be able to:
• Recognize patients with MDRO and/or Clostridium
difficile infections (or colonization)
• Conduct surveillance (track and monitor reports) within
the facility
• Explain the role of data feedback
• Identify best practices during transfer of a patient to
another facility

Our facility… Yes No Don’t know
1. uses standard definitions (such as McGreer criteria or CDC NHSN definitions) to determine if a resident has an infection
2. reviews provider notes to determine if a resident has an infection
3. maintains a list of residents with healthcare-associated infections in a log book
4. keeps a record of healthcare-associated infections in an electronic spreadsheet or database
5. performs house-wide surveillance of infections among our residents
6. performs targeted surveillance for specific infections among our residents
7. tracks rates of infection over time to identify trends ,e.g., monthly rate, quarterly rate, annual rate
8. creates summary reports (e.g., trends) of healthcare-associated infections
9. reports rates of infections by device days (e.g., # UTIs/1000 urinary catheter days/month)
10. shares infection surveillance data with facility Board members
11. shares infection surveillance data with facility leadership (i.e., CEO, DON, ADON, Medical director)
12. shares infection surveillance data with unit managers
13. shares infection surveillance data with all facility nursing staff
14. shares infection surveillance data with all physicians providing care to residents

Definition of Infection for Surveillance
The following 3 conditions must apply:
• All symptoms must be new or acutely worse
• Non-infectious causes of signs and symptoms
should always be considered before a diagnosis
of infection is made
• Identification of infection should not be based on
a single piece of evidence

Some Infection Prevention and Control Policies and its Impact on Surveillance
• Infection surveillance - either ‘whole-house’ (i.e. all
residents) or ‘targeted’ toward high risk/high
volume…
• Note disease trends
• Report data internally – weekly, monthly, quarterly
and as needed

• a stool test result positive for the presence of toxigenic C. difficile or its toxins or colonoscopic or histopathologic findings demonstrating pseudomembranous colitis.

Infection Rate
Represents infection during a period of time in relation to a unit of population (percent or per n population)
PERCENTAGE OF RESIDENTS WITH INFECTION
= # of infection x 100 = Rate of Infectionave. resident census(for the month)
= 4 CDI on WEST x 100 = 4% of residents had CDI in April 100 residents (on WEST)
![Page 22: Long-term Care Facility: Surveillance of MDRO and Clostridium difficile Infections](https://reader036.vdocuments.site/reader036/viewer/2022062309/568147a4550346895db4df9c/html5/thumbnails/22.jpg)
Resident-days as a Denominator
• Who records resident-days in your facility?• At the same time each day, the total number
of residents is recorded.• At the end of the month, the total is added up
for the month = resident days.

Estimation of Infection Rate
INFECTION (INCIDENCE) RATE= Number of xxx infections x 1,000 days
Number of resident days in the month
Rate of CDI on WEST Unit:= 4 x 1,000 = 1.33 CDI per 1000 resident-days
(3000)
