- the method further comprises that the number of actuations (SpEn) of the at least one electronic disinfectant dispenser observed in the specified observation period is stored individually in a data memory of the data processing unit for a respective day of the week and / or for respective stations of the facility.
- observation data for respective days of the week and / or respective stations or areas of the facility advantageously enables a more precise estimate of the hand hygiene compliance value, since these data, for example, indicate different bed occupancy in the facility on different days of the week and / or individual hand hygiene behavior of the staff in different wards of the facility, which, for example, require more or less indicated hand hygiene actions by the medical staff depending on the subject area.
- correction factor k a it would be conceivable and advantageous to improve the accuracy of the estimated compliance rate to use a correction factor k a in order to compensate for different numbers of patient receipts in the recording period T2 (compared to the observation phase T1).
- the correction factor k a would then have to be multiplied by the compliance value HHCT2.
- the correction factor k a must be less than 1.0 in the case of an above-average number of receipts (compared to the observation phase T1), since more patient encounters (and thus donor activities) will take place with an above-average occupancy and the actual compliance is overestimated as a result.
- the correction factor k a if the number of receipts is below average compared to the observation phase T1, the correction factor k a must be greater than 1.0.
- a further correction factor k b could be used in a corresponding manner in order to compensate for a change in the personnel code compared to the situation in observation phase T1.
- the correction factor k b would have to be less than 1.0 in the case of an improved staff situation (more staff per patient compared to the observation phase T1), since with With above-average staffing, more patient encounters can take place and the actual compliance is overestimated as a result.
- the correction factor k a can be determined, for example, by forming the quotient from the number of patient receipts in the observation phase T1 and the number of patient receipts in the respective acquisition phase T2.
- the correction factor k b can be determined on the basis of the personnel equipment in phases T 1 and T2.
- the correction factor k a can be the ratio of the employee hours during the specified recording period (T2) (MAh) to the average employee hours per time unit during the specified observation period (T1) (MAh Tl 24 h ).
- the correction factor k a can be determined by the ratio of the ward-wise care expenditure of all patients in the specified recording period (T2) (V stat ) to the average, ward-wise care expenditure of all patients per unit of time during the given observation period (T1) (V statTl 2 4n ) are formed.
- Combinations of two or more quotients by means of multiplication to form a single correction factor k a are also possible and advantageous, for example:
- the method also includes that the data processing unit is connected to the disinfectant dispenser via a network. Due to the fact that the health care facility has a large number of disinfectant dispensers, usually in each treatment or patient room, a centralized recording of the counting data of the respective actuations of the electronic disinfectant dispenser can be made possible.
- the method further comprises that the calculated numerical, in particular percentage, value of the hand hygiene compliance (HHC T 2) of the staff and the number of actuations (SpEi2) of the at least one electronic disinfectant dispenser in the health care facility for the predetermined recording period is stored in the data memory of the data processing unit and provided with a time stamp.

- SpEi2 number of actuations
- the storage of the hand hygiene compliance values (HHC T 2) in the data memory of the data processing unit has the advantage that, for example, a historical Evaluation or a course of the hand hygiene compliance of a relevant target group, for example the staff of a specific ward, can be carried out. Likewise, for example, a comparison of the hand hygiene compliance of the staff at different stations or areas of the health care facility can be carried out.
- the method further comprises that, if there is a discrepancy between an, in particular average, observed numerical, in particular percentage, value of the hand hygiene compliance (HHCn) of the staff in the healthcare facility for an observation period T1 and the recorded numerical, in particular percentage, value of the hand hygiene compliance (HHC T 2) of the staff in the health care facility for the predetermined recording period T2 is greater than or equal to a predetermined threshold value (for example greater than or equal to 20%), a first warning message is displayed on the display device becomes that an observation data set of the data processing unit should be updated.
- a predetermined threshold value for example greater than or equal to 20%
- An average value of the hand hygiene compliance (HHCn) of the staff for an observation period T1, based on a statistical survey, can be estimated, for example, by observing the number of all indication-related hand hygiene actions (HHAIND) observed in observation period T1 by the number of all in observation period T1 Hand hygiene opportunities (HDGn) are shared.
- HHAIND indication-related hand hygiene actions
- HDGn Hand hygiene opportunities
- the display of the warning message thus advantageously indicates to the user that the displayed or calculated hand hygiene compliance values differ significantly from the observed values and that there could be a change in the conditions on the basis of which the observed values were created.
- the method also includes that if the calculated numerical, in particular percentage, value of the hand hygiene compliance of the staff in the facility is less than or equal to a predetermined threshold value, a second warning message is displayed on the display device that the hand hygiene compliance value per patient encounter has fallen short of.
- the staff of the facility can thus be informed in an advantageous manner by the warning message that a current level of hand hygiene compliance of the relevant target group, for example station or area of the facility, is not currently available has been achieved and therefore measures to improve hand hygiene compliance should be taken.
- the compliance determined over a longer period of time, for example over the past seven days, can advantageously be displayed to the staff. This can be done by setting as seven days as the recording period T2 for the donor activities (SpEi2).
- Any type of display device such as monitors, displays or lamps, is suitable for displaying hand hygiene compliance.
- acoustic displays would also be conceivable.
- a display device designed in the manner of a traffic light would also be conceivable, whereby, for example, red could indicate an inadequate hand hygiene compliance rate, yellow an acceptable hand hygiene compliance rate and green a desirable hand hygiene compliance rate.
- the method further comprises that the electronic disinfectant dispenser has a wireless communication device for communication with the data processing unit, and wherein the display device is formed by a signal device, a screen and / or a mobile device, in particular a mobile radio terminal.
- Equipping the electronic disinfectant dispenser with a wireless data communication device thus advantageously enables effective communication with the data processing unit.

- a conversion factor UF could be calculated from the values obtained for HHAI N D, SpEn and HDGn using the calculation method shown above:
- the conversion factor (UF), the value of which is 0.00268 in the present example, can now be used to obtain a hand hygiene compliance rate (generally HHC T 2 or HHC T 2-24 h for any period T2 following the observation period) for a period of 24 h as in the present example)) on the basis of the donor events (SpEi2) recorded by the at least one electronic disinfectant dispenser in period T2.
- the length of the time period T2 must correspond in its length to the time unit t ze that was used during the statistical determination of the conversion factor (UF), i.e. 24 hours in the present example.
- the hand hygiene compliance rate (HHC T 2) on the selected day is 37.5% higher than the determined hand hygiene compliance rate (HHCn) of the observation phase T1.
