New England Baptist Hospital, Boston, MA
Objectives
Demonstrate how one hospital used the new CDI surveillance definitions to identify an increase of CDI on one nursing unit.
Describe enhanced environmental controls to reduce transmission of CDI
Describe the new Clostridium difficile Infection (CDI) Collaborative Definition
June 2008
Received the CDI Surveillance Working Group CDI definitions at the APIC Conference
Presented the new surveillance definitions to the Infection Control Committee
Reclassified cases in July 2008 Identified one nursing unit with 76% of the
cases of HA-CDI Several of the patients had also been in the
ICU and were transferred in an ICU bed rather than stretcher, and often went back and forth between the two units in the same bed
Patients were being removed from Special Contact Precautions after diarrhea stopped, prior to discharge – housekeeping didn’t know the room needed to be cleaned with bleach or cubicle curtains changed
New Surveillance Definitions
Initial Investigation August 2008 •FY08 = 24 Patients with positive C.difficile
titers – 3 from outpatient locations –21 from inpatients (87.5%)
•Nursing Unit - Developed Signs and Symptoms: –J4 East 16/21 cases (76%) –L 5 1/21 cases ( 5%) –5 East 3/21 cases (14%) –ICU 1/21 cases ( 5%)
3 of 16 Jenks4East cases were in room 465
- 2 of the CA-CDI (community-acquired) cases were in room 465
Poster we presented at APIC 2007 showing CDI with room association – 28 patients had been in 42 rooms!

FY2008 - NEBH Cases Per New Definitions
C.Difficile Team - August 08
Formation of C.Difficile Team: Dr. Camer (Chief of Surgery) Dr.
Lui (Chief of Gastroenterology), Sharon Connolly, RN – Nurse Manager, Sue Cohen,MT (ASCP) Microbiology Supervisor, Pam Dejoie, Maureen Spencer, RN, Infection Control
Met weekly, reviewed literature, formulated control measures, designed a retrospective case review, and educational offerings
Instituted Use of Chlorox Bleach Wipes
Enhanced Education for Staff Changed patient transfer
procedure Stretcher (not in bed)
Retrospective Case Review of all CDI cases
Enhanced Education
Transfers between units on stretchers versus contaminated bed Green tag flagging system for cleaned
equipment
Dinamap baskets with sanicloths and not allowed in precautions rooms
Spatial Separation of precaution cases Bleach wipes for all precaution rooms Enhanced cleaning of equipment
Nursing Unit Decontamination Decontaminated 19 rooms with dri-mist particle
generator that breaks down disinfectant into microscopic, negatively charged ion particulates.
These particulates are smaller than one micron in diameter and can access ALL surfaces of a room.
Particulates are negatively charged and stick to positively charged contaminants
Some evidence it will kill spores
Three day period – lease arrangement with company
Cost: ~$5000.00 for 19 rooms Issues: set off smoke detectors, prep time to seal
ventilation and doors

A case of C. difficile is defined as a case with the symptom of diarrhea without other known etiology. The stool sample will yield a positive result for laboratory assay for C. difficile toxin A and/or B. For purposes of this collaborative, C. difficile is limited to laboratory confirmed cases. This collaborative will track healthcare facility associated C. difficile
C. difficile (CDI) Collaborative Definition
C. difficile (CDI) Collaborative Definition
A patient classified as having a case of healthcare facility associated C. difficile is defined as a patient who develops diarrhea more than 48 hours after admission
ORA patient classified as having any symptoms that develop within 48 hours after discharge to another healthcare facility.
ORA patient discharged to home with lab confirmed C.diffIcile within 28 days from the day of discharge and no intervening admissions. . (Day of discharge counts as day 0) Also counts if C.difficile is identified on readmission to your facility.
If the time of admission and/ or the time of diarrhea onset and/or the time stool was collected are not available, CDI can be considered to be healthcare facility onset if onset of diarrhea, with a positive stool occurs on or after the third calendar day after the day of admission (which is day zero).
EACH PATIENT ONLY COUNTS ONCE
Within 8 weeks of index diagnosis
C. difficile (CDI) Collaborative Definition
A patient readmitted after 8 weeks counts as a new patient /case
(E.g. Monday admit, day 4 = Thursday)
FACILITY HA-CDI RATE
# HA CDI cases / 10,000 Patient Days
(exclude NICU days)
