Description

Title: Computer-implemented method and system for monitoring hand hygiene compliance

description

The present invention relates to a computer-implemented method for monitoring hand hygiene compliance of personnel, in particular medical personnel, in a health care facility.

The invention also relates to a system for monitoring hand hygiene compliance of personnel, in particular medical personnel, in a health care facility.

The invention also relates to a computer program and a computer-readable data carrier.

State of the art

In the field of hospital hygiene, correct hand disinfection is the most important individual measure for interrupting the transmission of pathogens and thus not only serves to protect employees, but also, in particular, to protect patients. This also applies to other health care facilities, such as rehabilitation facilities, outpatient medical facilities, medical centers, old people's homes or nursing homes.

For the assessment of whether hand disinfection is carried out during patient care at the right moment in order to effectively interrupt transmission paths, five indications are recorded in the literature and in the recommendations of the Robert Koch Institute.

These indications define at what point in patient care hand disinfection is necessary. Compliance is the extent to which a recommendation Order or rule is followed. In connection with the present application, the extent to which a hand disinfection following these five indications is carried out is referred to as “hand hygiene compliance”. The hand hygiene compliance can be shown as a percentage, whereby 100% hand hygiene compliance would correspond to a situation in which the affected employees of the health care facility always disinfect their hands for the five indications mentioned. In practice, hand hygiene compliance is usually well below 100%, for example 30%.

Hand disinfection according to the indications can be carried out in particular by washing hands (with soap and water) or by means of a hand disinfectant solution (usually an alcoholic solution). A hand disinfectant solution can be taken from the dispensers usually present in the patient area. Frequently the staff, in particular the medical staff, also carry so-called smock bottles from which a hand disinfectant solution can be removed.

Monitoring, i.e. the monitoring of hand hygiene compliance, has played an increasingly important role in recent years. On the one hand, monitoring the status quo of the quality of hand hygiene can be determined, which has become more and more important in the quality management of clinics in recent years. On the other hand, feedback based on monitoring is intended to achieve a permanent change in behavior towards very high hand hygiene compliance, so that patients are protected from avoidable complications caused by antibiotic-sensitive, but also antibiotic-resistant germs.

Hand hygiene monitoring is usually carried out through direct observation. This is due in particular to the fact that, according to the current state of the art, all five indications for hand hygiene can only be reliably recorded through direct observation and only then can statements on hand hygiene compliance be made possible.

At the same time, however, the implementation of direct observations is very time-consuming. This is particularly true when random samples are to be achieved, the number and composition of which allow a reliable determination of hand hygiene compliance and its development over time.

In the meantime, commercially available hand disinfectant dispensers with a counting function solve the problem of sample size and composition, since they are one Closely approximate the full survey of hand hygiene activity. However, such counting dispensers do not allow a statement to be made about hand hygiene compliance, as the indications relating to the respective donor activation would have to be recorded for this. Furthermore, the counting dispensers do not record if the hand disinfection was carried out by washing or using a smock bottle, although this is also an adequate hand disinfection measure.

EP 1 913892 B1 discloses a system that enables a person to monitor compliance with hand hygiene. The system includes a data reader that can be carried by the person, an entry trigger located at each doorway of a room, which entry trigger can activate the reader to record an entry event when the person enters the room , and a dispenser trigger located on each detergent dispenser.

The dispenser is located in the room or at the entrance of the room, wherein the dispenser trigger can activate the reader in such a way that it records a dispenser event when the person causes the dispenser to dispense detergent, the reader having a display device with which display a number of donor events and a number of entry events.

DE 102012 105368 A1 discloses a system for monitoring the use of hygiene devices. A portable identification means is to be carried on a user, the portable identification means having a means for storing at least one unique piece of information which allows the identification of the portable identification means. A hygiene device has a dispenser configured to dispense a disinfectant to a user and device control means coupled to the hygiene device.

The portable identification means includes a first capacitive coupling means coupled to the first receiving means for receiving electromagnetic signals via the first coupling means. The first receiving means is coupled to the control means in order to produce an electrical capacitive coupling between the control means and the body of the user.

The device control means is coupled to a first transmission means, and the first transmission means is coupled to a second capacitive coupling means to a establish electrical capacitive coupling between a user's body and the device control means.

The aforementioned solutions of the prior art have in common that the monitoring of the use of hygiene devices is carried out with technically complex means such as personal wireless communication means and / or in addition to the disinfection dispenser of a device arranged at the room entrance for detecting the entry of a user into the room. Furthermore, the above-mentioned solutions have the disadvantage that they ignore the indications for hand hygiene compliance or are not able to record them. Furthermore, the solutions mentioned cannot detect hand disinfection by washing hands or using smock bottles carried along, although these measures also contribute to indication-related hand hygiene compliance.

Accordingly, there is a need to provide a reliable method of monitoring hand hygiene compliance that can be technically implemented as simply as possible and that is able to monitor indication-related hand hygiene compliance.

The object is achieved according to the invention by a computer-implemented method for monitoring hand hygiene compliance of personnel, in particular medical personnel, in a health care facility according to claim 1, a system for monitoring hand hygiene compliance of personnel, in particular medical personnel, in a Health care facility according to claim 15, a computer program according to claim 17 and a computer-readable data carrier according to claim 18.

The invention relates to a computer-implemented method for monitoring hand hygiene compliance (HHC _T 2, hereinafter also referred to as _“hand hygiene compliance rate”) of personnel in a health care facility. The personnel are in particular medical personnel such as nursing staff or doctors. The health care facility (hereinafter also referred to as “facility”) is in particular a medical facility, in particular a hospital, a rehabilitation facility, an outpatient medical facility, a medical center, an old people's home or a nursing home . The method comprises recording a number of actuations (SpEi2) of at least one electronic disinfectant dispenser in a predetermined recording period (T2), with T2 preferably being 8 to 24 hours, in particular 24 hours.

The method further comprises transmitting the number of actuations (SpEi2) of the at least one electronic disinfectant dispenser recorded in the predetermined recording period T2 to a data processing unit connected to the at least one electronic disinfectant dispenser.

The electronic disinfectant dispenser can be a disinfectant dispenser that already includes electronic components that are permanently installed at the factory, or a disinfectant dispenser retrofitted with electronic components.

The method also includes calculating a numerical, in particular percentage, value of the hand hygiene compliance (HHC _T 2) of the staff in the health care facility for the specified recording period (T2) by means of the data processing unit by multiplying the number recorded in the specified recording period T2 of actuations SpEi2 of the at least one electronic disinfectant dispenser with a conversion factor (UF).

HHC _T2 «SpE _T2 X UF

The calculation is an estimate of the hand hygiene compliance rate HHC _T 2 on the basis of the statistically determined conversion factor UF.

The method also includes displaying the calculated numerical, in particular percentage, value of the hand hygiene compliance HHC _T 2 of the staff in the health care facility for the specified recording period T2 on a display device.

The invention also relates to a system for monitoring hand hygiene compliance (HHC _T 2) of personnel, in particular medical personnel, in a health care facility, in particular in a medical facility, with at least one electronic disinfectant dispenser which is set up to provide a Number of actuations (SpEi2) in a specified recording period T2 detect and transmit to a data processing unit connected to the at least one electronic disinfectant dispenser.

The system further comprises the data processing unit, which is set up to calculate a numerical, in particular a percentage, value of the hand hygiene compliance (HHC _T2 ) of the staff, in particular the medical staff, in the health care facility, in particular in the medical facility, by the to calculate method according to the invention.

The system also includes a display device which is set up to display the calculated numerical, in particular percentage, value of the hand hygiene compliance (HHC _T2 ) of the staff in the health care facility for the specified recording period T2.

The invention also relates to a computer program with program code in order to carry out the method according to the invention when the computer program is executed on a computer.

The invention also relates to a computer-readable data carrier with the program code of a computer program in order to carry out the method according to the invention when the computer program is executed on a computer.

One idea of the present invention is to provide an algorithm which can convert the electronically measured donor activations into a hand hygiene compliance rate.

Through this conversion, the data recorded on the at least one disinfectant dispenser, usually a plurality of disinfectant dispensers, can be significantly upgraded with regard to their use for hand hygiene monitoring. The upgrading of the counting data, which is abstract and confusing in itself, allows a user of the method to receive the upgraded information in a way that is more suitable for human understanding.

The technical extension of the conversion not only enables statements about the status quo of hand hygiene compliance. Rather, subsequent feedback can thereby also be displayed in or by the display device, which Feedback for the staff, for example for clinic employees, is meaningful in terms of content.

Further embodiments of the present invention are the subject matter of the further dependent claims and the following description with reference to the figures.

According to one aspect of the invention, the method further comprises that the conversion factor UF is calculated using statistically determined data (in an observation method carried out before the predetermined recording period T2), the statistically determined data by observing hand disinfection behavior of the staff in the health care facility are collected within an observation period T1 of n time units, in particular of n days. The observation is preferably carried out by human observers who are in the patient area and observe and record the hand disinfection behavior of the staff. According to a further preferred embodiment, cameras are present in the patient area so that the human observers can observe and record the hand disinfection behavior of the staff at a location remote from the patient area. According to a third preferred embodiment, cameras are present in the patient area, the monitoring and recording of the hand disinfection behavior taking place automatically using methods of artificial intelligence. For example, a “deep learning” algorithm can be used for this, which is initially trained on the basis of the observation and evaluation of the hand disinfection behavior of the staff carried out by human observers.

The use of surveillance cameras requires the approval of the staff and the patient for camera surveillance in the area.

According to a further preferred embodiment, the hand disinfection behavior of the staff can be observed by means of sensors which are attached to the at least one disinfectant dispenser and / or to a person belonging to the staff. The sensors can be sensor wristbands with acceleration sensors and / or position sensors.

The length (ΪZE) of each of the n time units of the observation period (T1) is preferably 8 to 24 hours, particularly preferably 24 hours. For example, it is possible to use the observation period (T1) on 10 consecutive days and here to be scheduled between 6 a.m. and 2 p.m. The length (ΪZE) of each of the 10 time units of the observation period (T1) in this example is 8 hours and n is 10. Preferably, time units of a length (ΪZE) of 24 hours are provided for the observation period (T1), so that in a single Time unit, all encounters usually occurring within a whole day between the staff and the patients or residents will occur and can thus be observed. In particular, it is proposed to set 24 hours for the observation period T1, with the 24 hours covering the period from midnight to midnight.

To calculate the conversion factor UF, the data collected in the observation period T1 can thus be used in an advantageous manner in order to effectively convert the recorded number of actuations (SpEi2) of the at least one electronic disinfectant dispenser in the specified recording period T2 into a numerical, in particular percentage, Value of the hand hygiene compliance HHC _T 2 of the personnel in the health care facility for the specified recording period T2.

According to a further aspect of the invention, the method further comprises that the statistically determined data by section-by-section observation of the hand disinfection behavior of the staff in the health care facility in a number z of randomly selected time windows (T 11 ... T 1 _z ) within the observation period T1 are raised.

The random selection of the time windows within the observation period T 1 thus advantageously enables the most accurate possible mapping of an actual hand disinfection behavior of the staff in the health care facility.

According to a further aspect of the invention, the method further comprises that in the number z of randomly selected time windows (T 11 ... T 1 _z ) within the observation period T1, a number of indication-related hand hygiene actions (HHAIND) by the staff and a number of hand hygiene opportunities (HDGn) of the staff are recorded, and a total number of actuations (SpEn) of the at least one electronic disinfectant dispenser carried out in the entire predetermined observation period T1, in particular by an electronic device of the electronic disinfectant dispenser, being recorded. Furthermore, the following data can be recorded during the specified observation period T 1:

- the number (HDzam) of hand hygiene actions of the electronic disinfectant dispensers in the patient area

- the number of patient _{encounters {Pat B i} h) _> which are observed in the specified observation period T 1 during a period of 24 hours,

- the number of patient encounters (Pat _{B T1} ) over the entire observation period T 1,

- the patient's day (PT _T1 ) in the specified observation period (T1), where (PT _T1 ) is defined as shown below,

- the number (MAh _{Tl 24h} ) of the average employee hours worked per time unit during the specified observation period (T1), whereby the number (MAh _T124h ) of the average employee hours is defined as shown below, and

- the average, station have supply effort (P _{stat, 71.24 / 1)} _{(, 71.24 / 1} V _stat) wi ^e is defined presented below all the patient per unit time during the predetermined monitoring period (T1), wherein the average, station as utility costs .

In connection with the present invention, “movement data” refers to data that are recorded by a sensor and provide information on the location, speed and / or acceleration of a person or an object. The object is preferably an electronically detectable marking (also referred to as “tags”) that is carried by a person.

Light barriers, television cameras or capacitive sensors, for example, can serve as motion sensors. Tags that are carried by people can include inclination sensors or acceleration sensors, for example.

Hand hygiene actions include, in particular, hand disinfection using the electronic disinfectant dispenser available in the patient area, hand disinfection using a smock bottle carried by the staff, and hand disinfection by washing hands. In connection with the present invention, indication-related hand hygiene actions are those hand hygiene actions which are carried out in accordance with the five indications mentioned at the outset, based on the recommendations of the Robert Koch Institute.

The expression “patient _{encounter” (Pat B} ) means an intended meeting of an employee (staff) of the health care facility with a patient or resident of the facility, the encounter being in connection with a care or treatment campaign. For example, a coincidental encounter between the staff and the patient in the hallway is not a patient encounter within the meaning of the present application.

A patient day (PT _T1 ) is understood to mean a day on which a bed was occupied by a patient on a fully in-patient basis. Patient days are the day of admission and each additional day of the hospital stay without the day of transfer or discharge from the hospital. If a patient is admitted and transferred or discharged on the same day, this day counts as the admission day.

The average, ward-wise care expenditure of all patients per unit of time during the given observation period (T1) is _{denoted by (V stat,} ri _{, 24 i} ). The average, ward-wise care expenditure (V _stat, ri _{, 24 i} ) can be determined, for example, using the Therapeutic Intervention Scoring System (TISS) or the Simplified Acute Physiology Score (SAPS).

Further proximity data and movement data can also be recorded and evaluated.

In connection with the present invention, “proximity data” is understood to be data that reproduce the relative distance between a user and a sensor or between an electronic marker and a sensor. In a preferred embodiment, the user (staff) carries an electronic marker with them, while the sensor is attached in a stationary manner.

The proximity data are recorded by proximity sensors and the movement data by movement sensors. The proximity sensors are, for example, inductive or capacitive proximity switches, whereby also magnetic or optical proximity switches are conceivable. Alternatively, proximity switches or light barriers based on ultrasound can be used.

Hand hygiene opportunities are those events during a patient encounter in which hand disinfection is necessary or indicated according to the five indications based on the recommendations of the Robert Koch Institute. For example, provides entering the patient room is a first indication for hand disinfection. The hand hygiene opportunities detected by observation in the randomly selected time windows (T1i ... T1 _z) within the observation period T 1 products are referred to herein as HDGn.

The indication-related hand hygiene actions recorded overall by means of observation in the randomly selected time windows (T1i ... T1 _z ) within the observation period T1 are referred to here as (HHAIND).

As a result of the observation, the observation data obtained in the randomly selected time windows (T1i ... T1 _z ), in particular the number of indication-related hand hygiene actions (HHAIND) and the number of hand hygiene opportunities (HDGn), can advantageously be related to the actuations carried out on the at least one electronic disinfectant dispenser be put in relation.

In addition to the data collected during the observation period T 1, data can be recorded during the collection period T2. In addition to the number of actuations (SpEi2) of at least one electronic disinfectant dispenser in a given recording period (T2), the collected data can include the number of patient encounters (Patß _{24 / li} ) for one day during the given recording period (T2) and the patient's day (PT _{2ih, i} ) during the specified recording period (T2).

The data obtained during T2 is called dynamic data.

The dynamic data can also include the employee hours during the specified recording period (T2) (MAh _T2 ) and the care costs for all patients in the given recording period (T2) (P _stat, r2).

If dynamic data are included in the calculation of the conversion factor (UF), this conversion factor changes over the recording period (T2). According to a further, particularly preferred aspect of the invention, the method further comprises that the conversion factor UF is calculated by forming a quotient from a first multiplication result and a second multiplication result, the first multiplication result being multiplied by the number of recorded indication-related hand hygiene actions (HHAIND) the number of n time units is formed, and the second multiplication result is formed by multiplying a total number of the total number of actuations (SpEn) of the at least one electronic disinfectant dispenser carried out in the predetermined observation period T1 by the number of detected hand hygiene opportunities (HDGn). The length (ΪZE) of each of the n time units of the observation period must correspond to the length of the specified recording period T2.

Surprisingly, it turned out that a conversion factor UF, which can be formed from the aforementioned quotient, represents a particularly realistic relationship between the actuations (SpEi2) of the at least one electronic disinfectant dispenser and hand hygiene compliance HHC _T 2 carried out in a period T2.

Mathematically, the conversion factor UF in connection with a preferred embodiment can be represented as

HHA _ind X n

UF = - - -

SpE _T1 X HDG _T1 where the variables have the meanings given above.

The length of the predefined acquisition period T2 and thus also the length (ΪZE) of each of the n time units is preferably 24 hours. _{A 24-hour compliance HHC24 h} can then be estimated for any point in time T2 using the data processing unit connected to the at least one electronic disinfectant dispenser and preferably recorded on a data carrier. The estimate can be made on the basis of the following formula: HHC24h «SpEi2 x UF S _P E

^ _T2 X ^HHA ^ xn SpE _T1 xHDG _T1

The determined value of HHC24 _h is preferably shown as a percentage. To do this, the result of the equation shown above is multiplied by 100.

In a further preferred embodiment, the conversion factor UF can be represented as

HHA _ind PT _T1

UF = SpE _{T i} HDG _T1 PT _{24h i} where the variables have the meanings given above. The patient day PT _{24h i} is recorded during the predetermined recording period T2. The other parameters which are included in the determination of the UF are recorded in this embodiment during the predetermined observation period T1.

In another preferred embodiment, the conversion factor UF is calculated according to

where the variables have the meanings given above. The number of patient encounters Pat _{B 24h i} is recorded during the recording period T2, while the other parameters of the UF are recorded in this embodiment during the predetermined observation period T1.

According to a further preferred embodiment, the variables have the meanings given above and the conversion factor is calculated from

The patient day PT _{24h i} is recorded during the predetermined recording period T2. In this embodiment, the other parameters of the UF are recorded during the predetermined observation period T 1. Pat _{B T1} is the number of patient encounters over the entire observation period T1, which are recorded as movement data via a sensor.

For a preferred embodiment, the length of the predetermined acquisition period T2 and also the length (ΪZE) of each of the n time units is 24 hours.

The numerical, in particular percentage, value of the hand hygiene compliance HHC _T 2 of the personnel in the health care facility for the past 24 hours can thus be calculated and displayed by the data processing unit.

The hand hygiene compliance HHC _T2 (general) or HHC _T 2-24 _h (in the case of T2 = 24 hours) calculated by the conversion factor thus represents a linear transformation of the number of actuations of the at least one electronic disinfectant dispenser in the specified recording period T2 .

The use of the conversion factor thus advantageously enables the randomly selected time window (T 11 ... T 1 _z ), in which the above parameters were observed, to be extrapolated to the hand hygiene compliance in a desired period of time T2, for example per day .

Assuming that a changed frequency of the donor events (SpEi2) results from a change in hand hygiene compliance, which is the case, for example, with an essentially constant bed occupancy in the health care facility, one based on the observed hand hygiene behavior of the staff can be used Estimation of hand hygiene compliance (HHC _T 2) can be carried out on the basis of the recorded actuations of the disinfectant dispenser (SpEi2).

According to a further aspect of the invention, the method further comprising that the number z of randomly selected time window (T1i ... T1 _z) within the n time units having the observation period between two and ten time slots per unit time, and wherein a length of the time window between 10 and 30 minutes, preferably 15 minutes. Such a selection of the number and length of the time windows thus advantageously enables an effective estimation of the actual hand hygiene behavior of the staff, in particular the medical staff, in the health care facility. According to a further aspect of the invention, the method further comprises that the specified recording period T2 is twenty-four hours, the specified observation period T 1 being greater than or equal to twenty-four hours, preferably at least 7 days, particularly preferably at least 10 days. An observation period T1 of at least seven days makes it possible to collect observation data from every weekday.

According to a further aspect of the invention, 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.

The presence of 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.

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. Correspondingly, 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. Similarly, the correction factor k _b can be determined on the basis of the personnel equipment in phases T 1 and T2.

Alternatively, 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 ). According to a further advantageous variant, 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:

, MAh V _stat k _a = - -.

MAh _{T1 2} 4h V _{stat T1 2} 4h

According to a further aspect of the invention, 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.

According to a further aspect of the invention, 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.

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.

According to a further aspect of the invention, 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. 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.

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.

According to a further aspect of the invention, 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 hand hygiene compliance of the relevant target group can be displayed to the staff on a daily basis (with T2 = 24 h), in which case the compliance rate of the previous day, for example, can be displayed on a monitor in the ward room as feedback for the staff. 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). Alternatively, an average compliance of a past period, for example the past seven days, can be displayed to the staff by averaging the daily (T2 = 24 h) compliance values of the past period.

Any type of display device, such as monitors, displays or lamps, is suitable for displaying hand hygiene compliance. In principle, 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.

According to a further aspect of the invention, 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. The display of the hand hygiene compliance values, for example on a mobile radio terminal as a display device, offers users the advantage that their hand hygiene behavior and the statistical data derived therefrom can be called up at any time via an app. Brief description of the drawings

Rather, the above summary and detailed description provides those skilled in the art with convenient guidance for implementing at least one exemplary embodiment, it being understood that various changes in the functional scope and arrangement of elements can be made without departing from the scope of the appended claims and their legal equivalents to deviate.

In general, this application is intended to cover changes, adaptations, or variations in the embodiments set forth herein. Embodiment

At a (non-intensive) station ("Station 2") of a clinic, the hand disinfection behavior of the medical staff (nursing staff and medical staff) was observed by human observers (medical students). The medical staff agreed to the observation. The observers were briefed on the recommendations of the Robert Koch Institute regarding the five indications for hand disinfection so that they could recognize the presence of one of the five indications.

The observation phase T1 lasted 10 time units (n = 10), the time units being days ( _tze = 24 h). Within these 10 days, 40 time windows (T11 ... T140) were selected at random so that there were 4 observation windows on each of the 10 days. The number z of the randomly selected time windows was a total of 40 time windows or 4 time windows per day. The length of each of the time windows (T 11 ... T 140) for observation was 15 minutes.

At least the following events were observed and noted in the selected time windows (T 11 ... T 140): The number of patient _{encounters Pat ß} , the number of hand hygiene opportunities (HDGn), the number of total hand hygiene actions (HHA), the number of Hand hygiene actions on the electronic disinfectant dispenser (HDzam) available in the patient area and the number of indication-related hand hygiene actions (HHAIND). As described above, hand hygiene actions include hand disinfection using the electronic disinfectant dispenser present in the patient area, hand disinfection using a smock bottle carried by the staff, and hand disinfection by washing hands. The total number of hand hygiene actions (HHA) also includes hand hygiene actions that are not indicated.

During the entire period T1, that is to say also outside the observation time window, the number of actuations (SpEn) of the at least one electronic disinfectant dispenser was automatically determined and electronically stored. The compliance rate (HHCn) for the observation period T1 was estimated by the quotient of the number of indication-related hand hygiene actions (H HAIND) and the number of hand hygiene opportunities (HDGn) and given as a percentage. The compliance rate (HHCn) for the observation period T 1 is therefore based on a statistical survey within the 40 time windows (TI1 ... TI40) of the observation period T 1.

The following values were obtained

The compliance rate (HHCn) for the observation period T1 was 32.7% in this example. A conversion factor UF could be calculated from the values obtained for HHAI _N D, SpEn and HDGn using the calculation method shown above:

HHA _ind xn 36 X 10

UF = - - - 0.00268

SpE _T1 X HDG _T1 1219 X 110

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.

If, for example, 140 donor events were recorded for the at least one electronic disinfectant dispenser on any period T2 of 24 hours following the observation period T1 (T2 = 24h; SpEi2 = 140), the relation shown above results in:

HHC _T2 -24 _h ^« SpE _T2 x UF = 140 x 0.00268 = 0.3752 or 37.52%

In this 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.
