Abstract

Objective:

To determine if the spread of Clostridium difficile-associated diarrhea is related to the use of electronic thermometers in an acute hospital and a chronic healthcare facility.

Design:

After finding that a significant percentage (20.8%) of electronic rectal thermometer handles were contaminated with C difficile, all electronic thermometers were replaced with disposables. A before/after trial was conducted to determine if the change to disposable thermometers would reduce the incidence of C difficile-associated diarrhea.

Setting:

The study took place in a 343-bed acute hospital and a 538-bed skilled nursing facility.

Patients:

All patients who underwent routine microbiological evaluation for nosocomially acquired diarrhea over a l-year period were included in the study. Nosocomial diarrhea was defined as 3 or more loose stools per day for 2 consecutive days and/or abdominal findings such as pain, distention, and ileus occurring 3 or more days after admission.

Results:

During the 6-month postintervention period, the incidence of C difficile-associated diarrhea was reduced from 2.71/ 1,000 patient days to 1.76/ 1,000 patient days in the acute hospital and from 0.41/1,000 patient days to 0.1 1/1,000 patient days in the skilled nursing facility The protective effect of the intervention was statistically significant for both facilities.

Conclusions:

Replacement of electronic thermometers with single-use disposables significantly reduced the incidence of C difficile-associated diarrhea in both acute care and skilled nursing care facilities. Data suggest that the rectal route may be important in the transmission of C difficile in these settings.
