Can improving patient hand hygiene impact Clostridium difficile infection events at an academic medical center?

      Highlights

      • An educational intervention study was completed to improve patient hand hygiene opportunities for patients at a large academic medical center.
      • After the intervention, it was possible to study the effects of improved patient hand hygiene on health care facility–onset Clostridium difficile infection events.
      • C difficile infection events decreased significantly (P ≤ .05) for 6 months after the intervention.
      • Patient hand hygiene may be an underused prevention measure for C difficile disease; successful implementation requires staff to engage the patient with opportunities, reminders, and encouragement to keep their hands clean.

      Background

      Hand hygiene plays an important role in the prevention of Clostridium difficile (CD) infection (CDI). Patient hand hygiene (PHH) may be a potentially underused preventative measure for CDI. Patient mobility and acuity along with a lack of education present obstacles to PHH for the hospitalized patient. Surveys of patients at our institution showed a need for increased PHH opportunities. The objective of this study was to increase PHH and to examine if PHH affected CDI at our hospital.

      Methods

      A biphasic, quasi-experimental study was performed to increase PHH through education for staff and to provide education, assistance, and opportunities to the patient for hand cleaning. PHH practice was assessed by patient surveys and analyzed by χ2 test. PHH effect on CDI was determined by following health care facility–onset CD laboratory–identified events data analyzed by National Healthcare Safety Network standardized infection ratios (SIRs).

      Results

      PHH opportunities improved significantly (P < .0001) after staff and patient education. CD SIRs deceased significantly for 6 months (P ≤ .05) after the PHH intervention.

      Conclusions

      PHH opportunities can be increased by providing education and opportunities for patients to clean their hands. PHH should be considered a relevant preventative measure for CDI in hospitalized patients.
