FRIDAY, June 17 (HealthDay News) -- Use of a glowing gel that
reveals microscopic germs on the skin may help children improve
their hand hygiene, according to new research.
The researchers said their findings, published in the June issue
Infection Control and Hospital Epidemiology, could have a lasting impact on efforts to reduce the spread of communicable disease.
"We found that using the gel alone to illustrate the areas of hands that may not be getting clean, even without verbal education, improves children's hand hygiene," said the study's principal investigator, Dr. Mary Groll of Northwestern University Children's Memorial Hospital in Chicago, in a journal news release.
For the study, researchers asked 60 children waiting in an
emergency room to apply Glo Germ Gel to their hands. The kids then
placed their hands under a black light, which highlighted any dirt
or bacteria with a yellow glow. Next, the children were asked to
wash their hands with soap and water before placing them back under
the black light. Based on the before and after results, researchers
scored the kids' hand hygiene.
"Waiting for the doctor is usually a tiresome and unproductive experience, but we were able to turn the waiting room into an interactive education center to help kids improve their hand hygiene," said the study's lead author, Dr. Anna Fishbein, a physician and researcher at Children's Memorial Hospital in the news release.
Following the test, about half the children received a brief
lesson in proper hand-washing techniques, such as washing for at
least 20 seconds, cleaning between fingers and washing finger
nails. The other children received no additional education.
Two to four weeks later, about three-quarters of the original
participants returned to have their hand washing re-evaluated.
Every child who followed up scored significantly higher on the
hygiene scale, regardless of whether they received extra
instruction on how to wash their hands.
"Considering the importance of hand hygiene in disease prevention, the implications of this study will have lasting impact in this community's effort to decrease the spread of illness," Groll said.
