OBJECTIVE: To evaluate the effectiveness of an automated hand hygiene compliance system (AHHCS) audible alert and vibration for increasing hand hygiene compliance.

DESIGN: A nonrandomized, before-and-after, quasi-experimental study of an AHHCS was implemented in several inpatient units. Over a 51-day period, the system’s real-time audible alert was turned on, off, and back on. Overall, hand hygiene compliance was compared between days with activated and deactivated alerts and vibration.

SETTING: This study was conducted at a level 1 trauma center, a regional academic health system with 1,564 beds.

PARTICIPANTS: The AHHCS was implemented in 9 inpatient units: 3 adult medical-surgical step-down units, and 6 adult intensive care units. The AHHCS badges were assigned to patient care assistants, registered nurses, physical therapists, occupational therapists, speech therapists, respiratory therapists, and physicians.

INTERVENTION: In the 9 inpatient units, selected healthcare staff were issued wearable badges that detected entry into and exit from a patient room. The audible alert was turned on for 16 days, turned off for 17 days, and then turned back on for 18 days, for a total of 51 days.

RESULTS: Utilization of the AHHCS real-time audible alert reminder resulted in sustained HH compliance ≥90%. When the alert and vibration were deactivated, HH compliance dropped to an average of 74% (range, 62%-78%). Once the alert resumed, HH compliance returned to ≥90%.

CONCLUSION: Utilization of an AHHCS with real-time reminder audible alerts may be an effective method to increase healthcare worker HH compliance to ≥90%. Users of AHHCSs should consider the use of real-time reminders to improve HH compliance.
