Increasing hand-hygiene compliance in clinical settings using a baby-eyes sticker: A field study

Abstract

This double-blind field study tested the effectiveness of a baby-eyes image in promoting healthcare workers’ hand-hygiene compliance in a hospital setting. Adults are inclined to take care of babies and aspire to be their role models; therefore, they should wash their hands thoroughly when being watched by babies. Participants were healthcare workers from the obstetrical and neonatology units of a women’s hospital in Hangzhou. We recorded and coded 3,360 hours and 10,325 hand-hygiene events over a five-week period—from 16 October to 20 November 2018. Three types of stickers, depicting baby eyes, adult eyes, or flowers, were placed above handwashing basins to compare hand-hygiene behavior between the three conditions. Each condition continued for one week, and experimenters interchanged the stickers in each unit to control for the location and sequence effects. Participants in the baby-eyes condition (72.9%) were more likely to use sanitizer than those in the flowers condition (69.4%; χ2 = 9.74, p
