Abstract

A hand hygiene behavior management system capable of monitoring and recording information generated by the operation of dispensers as a method of assessing behavior of a group as an indication of overall hygiene performance. The system generally includes a plurality of wireless communication devices with a first number of the wireless communication devices being disposed within or adjacent dispensers and operatively configured for sensing, monitoring and reporting information about the status and operation of the dispensers. A hierarchal communication network for access to a central host database; a data processor and hygiene management application software operatively configured to create hygiene management reports based upon the monitored dispenser data and a method to provide user interface.

Claims

1. A hand hygiene rate calculation and hand hygiene performance feedback system comprising a computer network with an application software administration center, and application software operative on the computer network which allows an application software user to direct the application software to interface with and query data or data-bases at sites or locations on the network where raw hygiene data is produced or stored, and with an application software user interface which enables the application software user to enter or choose a desired hand hygiene rate metric from a list of standard metrics, and to also input a hand hygiene rate denominator value such that execution of the application software will cause mathematical operations to be performed upon raw hygiene data from locations queried as selected by the applications software user, and utilizing the hand hygiene rate metric selected by the user and the hand hygiene rate denominator value input by the applications software user, the system will output processed data in the form of hand hygiene performance data or hand hygiene rate data.

2.

5. The system of claim 4, wherein the application software is configured to perform mathematical operations on raw hygiene data such that only the raw data required to assess the hand hygiene performance or hand hygiene compliance rate of a group or team of co-workers or personnel from which the raw data originated is operated upon, and which raw data includes time stamped soap or sanitizer dispenser usage data such as the number of times and when a particular soap or sanitizer dispenser or group of particular soap or sanitizer dispensers have been used, and such that any personnel identification information and any other information which links individual personnel identification to the raw data is necessarily excluded from mathematical operation by the application software.

6. The system of claim 1, wherein the application software user interface includes:

a field (14) where the user inputs or selects from a list of standard hand hygiene performance or hand hygiene rate metrics the hand hygiene performance or hand hygiene rate metrics or units which are to be assigned to the processed and output hand hygiene performance or hand hygiene rate data, and which includes at least one of the following;

hand washes or hand wash events per employee hour, hand washes or hand wash events per meal served, hand washes or hand wash events per average opportunity, hand washes or hand wash events per hospital bed-day, hand washes or hand wash events per patient-hour, and hand washes or hand wash events per hospital patient-day;

a field (15) where a time period is defined by the user such that only the raw hygiene data belonging to the defined period will be operated upon, and therefore the application software output will be hand hygiene performance data or hand hygiene rate data belonging only to the defined time period;

a field (15) where a numerical denominator value having units or metrics which match those as chosen by the user (14) are input into the system by the user;

a field (16) where the user inputs or selects from a list the desired rendering or format of the post execution processed data output;

a field (15) from within which the application software is executed such that the application software uses the parameters which have been selected and input into the application software user interface, and which causes the post execution processed data output to be saved on a network computer (6).

7. The system of claim 6, wherein the application software accepts the definition of a time period with an end point in the future such that the application software will automatically continue to operate upon raw hygiene data until such future end point is reached, and so that the application software output will be hand hygiene performance or hand hygiene rate data which is automatically and periodically updated as new raw hygiene data becomes available.

8. The system of claim 7, wherein the application software output is hand hygiene performance or hand hygiene rate data in real-time when the raw hygiene data is available in real-time.

9. The system of claim 6, wherein when the application software has been configured by the user via the application software user interface to use one of the standard hand hygiene metrics appearing in a list within the application software user interface (14), and when the application software has been sufficiently provided with a time period and numerical denominator value (15), the execution of the application software will cause mathematical operations which are characteristic to the application software to occur and operate upon queried raw hygiene data such that the output of the system is processed hand hygiene performance, or hand hygiene rate data which is saved in a data-base on a network computer (6).

10. The system of claim 9, wherein the execution of the application software performs the mathematical operations characteristic to the application software upon raw hygiene data such that only the raw data required to assess the hand hygiene performance or hand hygiene compliance rate of a group or team of co-workers or personnel from which the raw data originated is operated upon, and which includes time stamped soap or sanitizer dispenser usage data such as the number of times and when a particular soap or sanitizer dispenser or group of particular soap or sanitizer dispensers has been used, and such that any personnel identification information and any other information which links individual personnel identification to the raw data is necessarily excluded from mathematical operation by the application software such that the post execution output of the application software is characteristic of the group or team of co-workers from which the raw data has originated.
