## Abstract

A hand hygiene compliance benchmark is determined for a target institution based on observations of hand hygiene opportunities in a studied institution and relationships between the number of observed hand hygiene opportunities and characteristics of the studied institution. The benchmark for the target institution is determined based on target institution characteristics and the relationships between institution characteristics and observed hand hygiene opportunities of the studied institution. The benchmark for the target institution may be adjusted based on direct observation of hand hygiene opportunities in the target institution.

## Claims

### Claim 1

A method for monitoring compliance with hand hygiene guidelines by workers in a target facility comprising:
observing workers in a studied facility during an observation period to determine a study benchmark number of hand hygiene opportunities;
observing conditions of the studied facility during the observation period;
comparing conditions of the studied facility and the study benchmark number of hand hygiene opportunities to identify facility characterizing conditions with which the study benchmark number of hand hygiene opportunities is correlated by a characterizing condition relationship;
observing facility characterizing conditions for the target facility;
determining a benchmark number of hand hygiene opportunities for the target facility based on facility characterizing conditions for the target facility and the characterizing condition relationship;
monitoring worker hand hygiene events in the target facility to determine a monitored number of hand hygiene events; and
comparing the number of monitored hand hygiene events to the benchmark number of hand hygiene opportunities for the target facility.

### Claim 2 (depends on 1)

The method for monitoring compliance with hand hygiene guidelines by workers in a target facility of claim 1, wherein the studied facility and the target facility are healthcare facilities.

### Claim 3 (depends on 2)

The method for monitoring compliance with hand hygiene guidelines by workers in a target facility of claim 2, wherein conditions of the studied facility include a ratio of the number of patients in the studied facility during the observation period to the number of nurses responsible for patient care during the observation period.

### Claim 4 (depends on 2)

The method The method for monitoring compliance with hand hygiene guidelines by workers in a target facility of claim 2, wherein the study benchmark number of hand hygiene opportunities is based on one or more of the five moments of hand hygiene identified by the World Health Organization.

### Claim 5 (depends on 1)

The method The method for monitoring compliance with hand hygiene guidelines by workers in a target facility of claim 1, wherein the studied facility and the target facility are food preparation facilities.

### Claim 6 (depends on 5)

The method The method for monitoring compliance with hand hygiene guidelines by workers in a target facility of claim 5, wherein the study benchmark number of hand hygiene opportunities is based on one or more of the FDA recommended circumstances when a food worker should wash his or her hands.

### Claim 7 (depends on 2)

The method for The method for monitoring compliance with hand hygiene guidelines by workers in a target facility of claim 2, wherein conditions of the studied facility during the observation period include a case mix characterization of healthcare activity.

### Claim 8 (depends on 1)

The method for monitoring compliance with hand hygiene guidelines by workers in a target facility of claim 1 further comprising:
observing the number of hand hygiene opportunities in the target facility;
comparing the observed number of hand hygiene opportunities in the target facility to the determined benchmark number of hand hygiene opportunities for the target facility; and
adjusting the benchmark number of hand hygiene opportunities for the target facility to be consistent with the observed number of hand hygiene opportunities in the target institution.
