Key Points

Question  Does changing reminder signs more frequently in a hospital setting improve health care workers’ hand hygiene adherence?

Findings  In this cluster randomized clinical trial of 58 inpatient units in 9 acute care hospitals, overall hand hygiene adherence did not change significantly between before and during the intervention period at patient room entry or exit. In units assigned to change signs most frequently, hand hygiene decreased at patient room entry and exit.

Meaning  Hand hygiene adherence in the hospital setting is not likely to be affected solely by more frequent changes of reminder signs
