An exemplary device or badge for a hygiene compliance system includes a housing; a processor located in the housing; memory in circuit communication with the processor; wireless communication circuitry in circuit communication with the processor; and an additional time input in circuit communication with the processor. ## Claims ### Claim 1 A method of determining hand hygiene compliance rate for hospital staff comprising: providing a sensor configured to determine an entry event that is a function of a person's entry into a room; wherein the sensor comprises wireless communication circuitry for transmitting a signal indicative of the entry event; obtaining information related to a room status of the room; obtaining information indicative of an entry event indicating a person has entered the room; determining whether the entry event creates a hand hygiene opportunity; providing a dispenser for dispensing a product; obtaining information indicative of a dispense event indicating product has been dispensed; determining whether to credit the person with a dispense event; wherein determining whether the entry event created a hand hygiene opportunity is a function of the information related to the room status. ### Claim 2 (depends on 1) The method of claim 1 further comprising obtaining information about a role of the person, and wherein determining whether the entry event created a hand hygiene opportunity is a function of the role of the person. ### Claim 3 (depends on 1) The method of claim 1 further comprising obtaining a signal that the person has exited the room and determining whether the exit event created a hand hygiene opportunity, wherein determining whether the exit event created a hand hygiene opportunity is a function of the information related to the room status. ### Claim 4 (depends on 3) The method of claim 3 further comprising obtaining information about a role of the person, and wherein determining whether the exit event created a hand hygiene opportunity is a function of the role of the person. ### Claim 5 (depends on 1) The method of claim 1 wherein the information related to room status comprises information indicative of contact precautions. ### Claim 6 (depends on 5) The method of claim 5 wherein the contact precautions are indicative of a C-Difficile infection. ### Claim 7 (depends on 6) The method of claim 6 wherein determining whether to credit the person with a dispense event is a function of whether the dispense event is a soap dispense. ### Claim 8 (depends on 1) The method of claim 1 wherein the information related to room status comprises information indicative of occupancy of the room. ### Claim 9 (depends on 1) The method of claim 1 further comprising determining an additional hand hygiene opportunity is created as a function of a period of time. ### Claim 10 (depends on 1) The method of claim 1 further comprising determining a compliance rate that is a function of one or more opportunities and one or more dispense events. ### Claim 11 A method of determining hand hygiene compliance rate for staff comprising: providing a sensor configured to determine an entry event that is a function of a person's entry into a room in a hospital; wherein the sensor comprises circuitry for transmitting a signal indicative of the entry event; obtaining information related to a room status of the room; obtaining a signal that a person has entered the room; determining whether the entry event into the room creates a hand hygiene opportunity; providing a dispenser for dispensing a product; determining a dispense event has occurred as a function of the dispenser dispensing product; determining whether to credit the person with a dispense event; wherein determining whether the entry event created a hand hygiene opportunity is a function of the information related to the room status; and determining a compliance rate as a function of opportunities and dispense events. ### Claim 12 (depends on 11) The method of claim 11 further comprising obtaining information about a role of the person, and wherein the compliance rate is a function of the role of the person. ### Claim 13 (depends on 11) The method of claim 11 further comprising obtaining a signal that the person has exited the room and determining whether the exit event caused a hand hygiene opportunity, wherein determining whether the exit event triggered a hand hygiene opportunity is a function of the information related to the room status. ### Claim 14 (depends on 13) The method of claim 13 further comprising obtaining information about a role of the person, and wherein determining whether the exit event created a hand hygiene opportunity is a function of the role of the person. ### Claim 15 (depends on 11) The method of claim 11 wherein the information related to room status comprises information indicative of contact precautions. ### Claim 16 (depends on 15) The method of claim 15 wherein the contact precautions are indicative of a C-Difficile infection. ### Claim 17 (depends on 16) The method of claim 16 wherein determining whether to credit the person with a dispense event is a function of whether the dispense event is a soap dispense. ### Claim 18 (depends on 11) The method of claim 11 wherein the information related to room status comprises information indicative of occupancy of the room. ### Claim 19 (depends on 11) The method of claim 11 further comprising determining an additional hand hygiene opportunity is created as a function of a period of time. ### Claim 20 A method of determining hand hygiene compliance rate for staff comprising: providing a sensor configured to determine an entry event that is a function of a person's entry into a room; wherein the sensor comprises circuitry for transmitting a signal indicative of the entry event; obtaining information related to a room status of the room; obtaining a signal that a person has entered the room; determining whether the entry event into the room creates a hand hygiene opportunity; determining a role of the person; providing a dispenser for dispensing a product; determining if a dispense event has occurred; determining whether to credit the person with a dispense event; wherein determining whether the entry event that created a hand hygiene opportunity is a function of the information related to the room status and the role of the person; and determining a compliance rate as a function of opportunities and dispense events.
