Description

The invention relates to a method for operating a digital ward trolley which has a computer unit, a monitor and an input device, the monitor and the input device being in communication with the computer unit.

Medical trolleys in general and digital medical trolleys in particular are well known from the prior art, which is why separate printed evidence is not required at this point. It is therefore only an example of the DE 20 2021 103 339 U1 , the DE 20 2016 106 241 U1 and the DE 20 2015 106 146 U1 referred.

What the aforementioned digital ward trolleys have in common is that they have a computer unit, a monitor and an input device. The monitor and the input device are in communication with the computer unit.

In the case of intended use, the user enters data via the input device, which data can be processed by the computer unit and displayed on the monitor. In particular, a keyboard and/or a computer mouse come into consideration as possible input devices.

According to a first previously known design, the computer unit is accommodated in a cabinet body of the ward trolley. For this purpose, it can be provided, for example, that the storage space provided by the cabinet body is divided into two, with one part serving to accommodate utensils and the other part serving to accommodate the computer unit.

According to a second previously known design, the computer unit is accommodated by a housing of the monitor. In this case, a so-called all-in-one monitor is used, which not only houses the actual monitor, but also the computer unit. A particular advantage of this solution is that the storage space provided by the cabinet body can be used entirely to accommodate utensils.

Visit trolleys of the aforementioned type are used as intended to support and/or document a patient visit. The data recorded during such a visit are processed by the computer unit as patient-related data and can be displayed on the monitor if necessary. The entire file of a patient is preferably available digitally, so that it is possible during a visit to call up individual data from the patient file and, in particular, to display and discuss it in the presence of the patient. The ambulance trolley is usually operated by nursing staff or doctors.

It is the object of the invention to propose a method for operating a generic ambulance trolley that enables safe handling of patient-related data.

To solve this problem, the invention proposes a method for operating a digital ward trolley, which has a computer unit, a monitor and an input device, the monitor and the input device being in communication with the computer unit with the following steps:

• - transmission of an identifier uniquely identifying a first user of the ward trolley to an evaluation unit of the computer unit by the first user,
• - Receiving a first data set by the evaluation unit, the data set having patient-related data recorded by the user using the input device and a time stamp,
• - assignment of the data of the first data set to the user ID of the first user by the evaluation unit,
• - checking the data transmitted with the first data set for input authorization by the first user using the user ID of the first user by the evaluation unit,
• - Marking the data of the first record without input authorization,
• - Display of the data of the first data record marked as entered without input authorization,
• - transmission of an identifier uniquely identifying a second user by the second user,
• - Receiving a second data set, wherein the second data set has authorization data corresponding to the second user identifier and
• - Release of the data of the first data record marked as recorded without input authorization by means of the authorization data of the second data record.

According to a first method step, the method according to the invention provides that an identifier uniquely identifying a first user of the ward trolley is sent to the evaluation unit is transmitted to the computer unit, specifically by the first user. This can be done, for example, by the first user logging on to the computer unit with software support. Such a registration is preferably carried out using a user-selected user name in combination with a preferably user-selected or system-specified password. The user name and the password represent the unique identification of the user, so that all subsequent entries by the user can be assigned to the user made known to the computer unit through the registration.

The uniquely identifiable user ID is transmitted to the evaluation unit. The evaluation unit is part of the computer unit and is provided by it. The evaluation unit can also be mapped virtually in terms of software.

According to a second method step, a first data set is received by the evaluation unit. This data record has patient-related data recorded by the user using the input device, as well as a time stamp. Patient-related data are, in particular, data that relate to the patient and their state of health. In particular, patient-related data relates to data that is recorded by the user of the ambulance cart during a visit. Examples are data representing vital signs, such as body temperature, pulse and blood pressure. However, patient-related data in the sense of the invention also includes other data that relates to the patient, such as medication, medical history and/or data that relates to later billing.

In this context, it is of essential importance to the invention that a first data set is received by the evaluation unit, this data set including, among other things, data that the user has entered using the input device. The data record also contains a time stamp, which is preferably recorded automatically and added to the data record. The time stamp represents the point in time at which the patient-related data was recorded, so that the chronological order in which patient-related data was entered can subsequently be checked.

In a further method step, the data of the first data record is then assigned to the user ID of the first user by the evaluation unit. It is therefore determined which user has recorded the data of the first data set. The assignment is made via the user ID, which is known to the system from the previous user registration. As a result, it is documented which user recorded, recorded and entered which patient-related data.

In a further step, the data transmitted with the first data record is checked for input authorization by the first user using the user ID of the first user by the evaluation unit. According to this method step, it is checked whether the user who recorded the data of the first data record was actually authorized to enter this data. This check is carried out using the user ID, which is made possible due to the previous assignment of user ID and data.

It is therefore of essential procedural importance that an input can take place independently of the input authorization, i.e. an input is not refused due to a lack of authorization, but on the procedural side it is determined whether an input has been made with the corresponding authorization or not. In this way, it is ensured in any case that data entry is possible and that there is no unintentional loss of data due to a lack of entry authorization. Whether further processing of the entered data is possible depends on the input authorization.

For example, it can be provided that an entry for the prescription of a medication is only authorized if the stored user ID is that of a medical staff. However, the user ID of a nurse is not sufficient to be able to record a medication to be administered to the patient with a corresponding input authorization. Nevertheless, the nurse can record the medication to be administered and document it in such a way that an actual release for the administration of this medication is still required.

In the simplest case, for example, a nurse acts on the instructions of a doctor. The nurse then writes down the medication to be administered in the digital patient record, which is done in the sense of the method according to the invention in that she records data via the input device of the ward trolley, which is then received as a data record by the evaluation unit. This means that, on the instructions of the doctor, the system knows which medication a patient should receive. However, the medication is then not actually administered, not because the entry was made by a nurse who is not authorized to do so. However, the medication to be administered is recorded in terms of data and is therefore not lost to the patient's benefit.

According to a further method step, the data of the first data record is marked without an input authorization. Procedurally, sorting is therefore carried out between data for which there was an input authorization and data for which there was no input authorization. For example, if during a visit the nurse logged into the system enters patient-related data such as temperature, pulse and blood pressure on the one hand and the medication to be administered on the other hand, the data representing the temperature, pulse and blood pressure are entered with input authorization, the medication to be administered but without permission. Due to the identification of the data of the first data set provided according to the invention without an input authorization, the entered data can be sorted accordingly. Preferably, the data marked as having no authorization can be kept in a separate list, so that there is a simple overview of which data has already been entered without corresponding authorization.

According to a further method step, it is provided that the data of the first data record identified as being recorded without input authorization is displayed. This can be done in a separate dialog box or by simply identifying the data, for example with a special color marking. For example, the data entered can be displayed on a data form on the monitor, with data entered without authorization having a special color marking, for example red. It is thus easily possible to visualize data recorded without input authorization and thus to make it recognizable.

According to a further method step, it is provided that an identifier uniquely identifying a second user, for example of the ambulance trolley, is preferably transmitted to the evaluation device by a second user. After the entry has been made by a first user, a second user with a second identifier logs on to the ward trolley, for example. The registration can take place directly on the doctor's trolley or from another computer unit which is in communication with the doctor's trolley or a central data management system, for example via a radio link. In this context, it is of course also possible to use a server solution, according to which the software required to carry out the procedure is managed and called up at a central location, with the software being accessed remotely, for example via radio, also using the computer unit provided by the ambulance trolley. However, the sole decisive factor for carrying out the method according to the invention is that a second user can register with a second user ID, the second user ID being different from the first user ID.

According to a further method step, a second data record is received, for example by the evaluation unit, the second data record having authorization data corresponding to the second user identifier. With the second data set, no user-related or patient-related data is transmitted, but rather authorization data.

According to a last procedural step, the authorization data are used to release the data of the first data set identified as having been entered without an input authorization.

This removes the initial lack of input authorization for the recorded data and the data now appear as having been entered with input authorization. It is still documented on the system side that the initially unauthorized first user made an entry without authorization, but then released the second authorized user who was authorized to do so.

Thus, for example, it can be provided that data collection relating to a medication that has taken place without input authorization is subsequently authorized by the doctor responsible and this authorization can also be displayed in the system. The time stamp can also be used to reconstruct the point in time at which data was recorded and later released.

As can be seen from the above description of the invention, the method according to the invention allows patient-related data to be documented securely insofar as it is ensured that data can be recorded independently of authorization, but that a lack of authorization is displayed during data recording and the data collected in this way can subsequently be released, provided this is done by a user authorized for this purpose. This ensures data security and application security.

According to a further feature of the invention, it is provided that a plurality of data of the first data record identified as being recorded without input authorization and/or a plurality of re datasets can be released at the same time. It is thus possible to carry out the process in a simplified and rapid manner. This is because individual data does not have to be released separately in a respective method step, rather it is possible to release data that is preferably bundled into individual packets in just one method step at the same time. For example, it can be provided that all data on the topic of medication can be summarized and thus easily checked and released at the same time by a user responsible for this.

According to a further feature of the invention, it is provided that the patient-related data is recorded by means of a graphically supported input. This enables intuitive and therefore simplified data entry. In addition, the graphically supported input can ensure that possible errors in data entry are avoided.

"Graphically supported input" within the meaning of the invention means in particular that a graphical support, for example in the form of a diagram or other pictorial representations, is required for data input. For example, a so-called fever curve can be provided for entering data that represents the body temperature of a patient. A new temperature point can be marked in this fever curve with a simple mouse click and the associated data entered. As an alternative to this, it is of course also possible to enter the temperature value via the keyboard. However, the graphical support has the advantage of allowing immediate visualization of the entered data, which promotes perception and understanding of the entered data.

Of particular advantage in this context is the ability to represent the human body as a graphic input support. It is thus made possible to select specific body parts and/or regions for which data is then to be entered. In this context, it can also be helpful to provide a selection menu for predefined, possible data entries. A simplified input is also achieved in this way.

According to a further feature of the invention, it is provided that the input is made using a central data document. Redundant input and the input errors that may be associated with it are thus effectively avoided. A large number of different data documents are preferably provided for the data display, which serves for clarity and offers the possibility of summarizing data from specific subject areas. If a new entry has to be made within a topic complex, there is an automatic switch to the central data document that is intended for data entry. After the data has been entered, an automatic return to the data document originally used for display can then take place. This ensures that although different data documents can be used for a display, an input always takes place at a central point, so that the data entered here can be used in different data documents for display in the same way.

The method according to the invention is distinguished in particular by the fact that it enables simplified handling both during data input and during data output. There is always documentation regarding the recorded data, regardless of whether or not there is an input authorization. The input authorization can be made up for in the manner described above, which makes it possible to release data originally entered without input authorization, which are then also marked accordingly as such.

Further features and advantages of the invention result from the following description based on the figures. show it

• 1 in a schematic representation of a possible mode of operation of the method according to the invention and
• 2 a schematic representation of an exemplary processing of the method according to the invention.

1 shows the functioning of the method according to the invention in a purely schematic representation. A ward trolley 1, a central data management system 5 and a further computer device 6 are shown. The ward trolley 1 and the central data management 5 as well as the central data management 5 and the computer device 6 are each connected via radio for communication purposes, for example via a WLAN network. Accordingly, the ward trolley 1 and the computer device 6 can each communicate with the central data management system 5 and, in particular, can exchange data.

The ward trolley 1 in turn has a computer unit 2 , a monitor 3 and an input device 4 , the monitor 3 and the input device 4 being in communication with the computer unit 2 .

According to a typical application, a user enters data on the ward trolley 1, for example during a ward round. Both medical staff and nursing staff can be considered as users.

In the exemplary embodiment shown, the data recorded using the ward trolley 1 is transferred to the central data management system 5 . This can be done in real time or at a later time after prior user confirmation. The data stored in the central data management 5 are available for retrieval both for the ward trolley 1 and for a further computer device 6 . The additional computer device 6 can be a workstation computer, a digital terminal device such as a smartphone, for example, or some other computer device. The sole decisive factor is that the data stored by the data manager 5 can be accessed by the computer device 6 , ie it is possible for the data provided by the data manager 5 to be both displayed and changed by the computer device 6 .

As will be explained in more detail below, data can be entered using the ward trolley 1, depending on the user authorization either with input authorization or without input authorization. The data provided by the data management system 5 must therefore be distinguished according to whether they have been entered using the ward trolley 1 with or without input authorization. The data entered without input authorization can be released later, which can be done either by means of the ward trolley 1 or the computer device 6 . In particular, it is possible to have data recorded by non-medical personnel using the ward trolley 1, with this data being recorded without input authorization. At a later point in time, this data collected without input authorization can be released by authorized medical personnel. To release this data, the medical staff can use either the ward trolley 1 or the computer device 6, for example the workstation computer equipped for this purpose or the smartphone designed for this purpose.

The precise course of the method according to the invention results in particular from the schematic representation 2 , where the individual process steps are shown. The inventive method is based on 2 explained using the example of a ward round, with the ward round trolley 1 being operated by non-medical staff.

According to the first method step 10, the user of the ward trolley 1 has to register at the ward trolley 1. For this purpose, an identifier uniquely identifying the user of the ward trolley 1 is transmitted to an evaluation unit provided by the computer unit 2 of the ward trolley 1 . This unique identifier can be a user name in combination with a user password, for example.

Certain authorizations are stored in the system for every possible user of the ambulance trolley and/or for certain groups of users, as well as an input authorization for data to be subsequently entered.

According to a second method step 11, the user of the ward trolley 1 enters data, with a first data set being received by the evaluation unit. This data record has patient-related data recorded by the user using the input unit 4 on the one hand and a time stamp on the other.

The patient-related data is, for example, data that represents the body temperature of the patient on the one hand and data that represents a medication to be carried out later on the other.

Since the user of the ambulance 1 is not a medical staff, there is an input authorization for the data representing the body temperature, but not for the data relating to the medication. Nevertheless, it is possible to collect all data and entry of data relating to the medication is not refused for lack of authorization by the user. Complete data documentation is thus guaranteed.

According to a third method step 12, the data of the first data record is then assigned to the user ID of the first user by the evaluation unit. It is therefore documented which data has been recorded by which user, so that when there is a change in the user operating the ward trolley 1 it is clear which data recorded by the ward trolley 1 have been recorded by which user.

In a further method step 13, the data transmitted with the first data record is checked for input authorization by the first user using the user ID of the first user by the evaluation unit. The system therefore checks whether the user who recorded the data had user authorization for all recorded data.

In a subsequent step 14, those data are identified that have been recorded without input authorization. This data can preferably be sorted and in one be displayed in a separate list. It is therefore possible at any time to check whether and, if so, which data has been recorded for which there was no input authorization.

The data recorded without input authorization are displayed in a further method step 15 . This can be done on the ward trolley 1 itself or on another computer device 6 .

In a further method step 16, a second user logged on to the system, for example a user belonging to the group of medical personnel. Accordingly, provision is made for the second user to transmit an identifier that uniquely identifies this second user of the ambulance to the evaluation device. The transmission of the second identifier, i. H. a second user does not necessarily have to be registered with the aid of the ward trolley 1 , but can also take place via a further computer device 6 . It is crucial that a second user logs on to the system with a second ID that is different from the ID of the first user.

According to the exemplary embodiment, the second user belongs to the medical staff and is therefore authorized to release data previously entered by the first user.

It is therefore provided according to a further method step 17 that a second data set is received by the evaluation unit, the second data set having authorization data corresponding to the second user identifier. Then, in a last method step 18, the data of the first data set identified as being recorded without input authorization is released by means of the authorization data of the second data set.

In the exemplary embodiment explained, the first user has entered data relating on the one hand to the temperature of the patient and on the other hand to the medication to be administered. The data representing the temperature could be entered by the first user with input permission. The data relating to the medication, on the other hand, were recorded without input authorization, so that the data relating to the medication are now released with the last procedural step of release. This subsequent release is noted in the data administration 5, it being possible to trace which data was entered at what time, who is responsible for the data entry and who ultimately subsequently authorizes data entry that took place previously without an entry authorization, i. H. released.
