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

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.

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

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.

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.

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%.

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.

To determine whether feedback on antimicrobial use improves physician compliance with local hospital guidelines on antimicrobial prescribing.

In this time series analysis, in which a historical control period was compared with an intervention period, all orders for antimicrobials (except those for surgical prophylaxis) placed from November 1, 2002, through April 30, 2004, were prospectively evaluated by an antimicrobial management team (AMT) for compliance with local hospital guidelines. During the control period, orders were evaluated to determine compliance with hospital guidelines before and after recommendations by the AMT were provided to physicians. Feedback was given for the second 9-month period in the form of a weekly report to prescribing physicians, a monthly hospital newsletter, and a quarterly report to various hospital committees. During the intervention period, orders were evaluated to determine compliance with hospital guidelines before and after recommendations by the AMT were provided to physicians.

The Veterans Affairs Medical Center, a 110-bed facility, in Louisville, Kentucky.

Internal medicine physicians and general surgeons.

A total of 2,807 antimicrobial courses were evaluated. Compliance with hospital guidelines before AMT recommendations was 70% during the control period and 74% during the intervention period (P = .02). Compliance after AMT recommendations was 90% during the control period and 93% during the intervention period (P ≤ .01).

The use of feedback had a significantly favorable impact on physician compliance with the hospital's guidelines on antimicrobial prescribing. Use of feedback should be added to the list of interventions that promote appropriate antimicrobial use in the hospital setting.
