Hand-Washing aka hand hygiene Remains #1 In Infection Prevention In Every Setting.
“Despite evidence to suggest that [hand hygiene] is important in preventing infection, hospitalized patients are often not provided the opportunity to clean their hands,” due to mobility and cognitive obstacles as well as lack of education, investigators wrote.
Education on patient hand hygiene significantly reduced the incidence of Clostridium difficile infection at University of Pittsburgh Medical Center Mercy Hospital.
First, they conducted baseline surveys to assess patient hand hygiene, which showed patients needed more opportunities to wash their hands. Then nurse educators provided staff with an educational presentation on the importance of patient hand hygiene for preventing infection, which included specific times they should encourage and assist patients with hand hygiene. Staff then provided education and assistance to newly admitted patients, and researchers conducted additional surveys after implementation of this intervention.
During the first phase of the study involving just four medical-surgical nursing units, patient hand hygiene education increased significantly after the intervention (P < .0001). Overall, 97 follow-up surveys showed the proportion of those who received hand hygiene education increased from 34% to 64%, the opportunities provided for hand hygiene increased from 60% to 86%, and the average number of times hand hygiene was performed daily increased from 2.7 to 3.75.
After expanding the intervention to the whole hospital in the second phase of the study, 189 follow-up surveys showed that patient hand hygiene education increased from 48% to 53%. Meanwhile, overall opportunities for hand hygiene remained unchanged from 68%, and daily frequency of patient hand hygiene did not change significantly (mean, 2.4 vs. 2.6 times per day).
Notably, CDI rates dropped significantly during the 6 months following hospital-wide implementation.
“[Standardized infection ratio] P values for Q2 and W3 (0.0157 and 0.0103, respectively) were significantly lower than expected (P .05),” investigators wrote. “The Q4 SIR, however, showed an increase to 0.3844 over the 2 preceding quarters.”
They concluded that these findings showed patient hand hygiene “should be considered a potential addition to CDI prevention measures in hospitalized patients.” – by Adam Leitenberger
