Use of gloves and handwashing behaviour among health care workers in intensive care units. A multicentre investigation in four hospitals in Denmark and Norway.

Glove use and handwashing frequencies (HW) were observed in intensive care units (ICU) in two university hospitals in Denmark and two in Norway. The study included a total of 1632 patient procedures performed by 325 persons. Handwashing (HW) has become an important part of general barrier precautions. Earlier studies have shown that health care workers (HCW) far too often neglect to wash their hands after patient procedures when handwashing is strongly recommended. Despite earlier claims that increased glove use in hospitals would discourage handwashing, our results showed that HCW washed their hands more often after glove use (57%) than when gloves had not been used (40%). This significant difference in HW frequency was also noted when similar procedures were carried out by HCW with or without gloves. This might be a matter of personal discomfort after wearing gloves, but could also be due to differences in awareness of hygienic aspects of patient care. In the two countries gloves were used on average at 17% of the procedures, but were not used appropriately for dirty procedures. The results of this study indicate that more effective methods for the implementation of appropriate glove use and HW should be emphasized.
