Abstract

The invention relates to a communication system for the interaction between medical laboratories and medical treatment centers. Centralized laboratories already make use of data communication for transmitting analytical data, of accepting or handling orders. According to the invention, all relevant laboratories and their specialized departments on the one hand and the medical treatment centers on the other hand are interconnected via data communication devices with an integrative central laboratory data base that is provided with a server computer. The required patient- and examination-related data are entered in a data entry module of a data input device in the commissioning treatment center and are forwarded in a coordinate manner via the central laboratory data base to the respective laboratory or laboratory department via data output devices in the commissioned laboratory or laboratory department. The samples to be analyzed are characterized and/or encoded in the treatment centers by means of the data entry modules according to predetermined criteria and are forwarded to the relevant laboratory or laboratory department. The analysis orders already booked are activated once the samples arrive in the laboratory and the analytical data are stored in the central laboratory data base and are transmitted to the commissioning treatment centers via data communication devices once the analyses are completed.

Description

The invention relates to a communication system for the Interaction between medical laboratories and doctor treatment facilities.

Due to a high material and personnel A medical laboratory will usually zen effort operated tral. For resident doctors there is a such a laboratory is therefore often in the form of a laboratory shaft, while university clinics and hospitals operate a central laboratory with several departments ben.

Many laboratories have already switched to the sub to provide search results so that they from the commissioning station or doctor's office per Da transmission can be called up. The accelerate does not require the transmission of the finished examination data, the order acceptance and processing takes place but still in the traditional way. A laboratory  can therefore still do its work insufficiently plan, because only when the order arrives with the associated sample materials on the Auf contract processing, i.e. the necessary investigations that necessary equipment and materials etc. decided can be. It is not uncommon for orders to be sent to a wide audience res, specialized laboratory or can not immediately because of an increased workload be tackled what the order processing treatment, often to the detriment of a patient, is delayed.

The invention is therefore based on the object Communication system for the specified purpose ben that the acceleration of order processing and the equalization of the workload allowed.

The object is achieved by the Merk male in the characterizing part of claim 1 together work with the characteristics in the generic term. Appropriate Embodiments of the invention are in the dependent claims Chen included.

According to this, all laboratories and their laboratory departments involved in the communication system, on the one hand, and medical treatment facilities, on the other hand, are networked with a server computer via data transmission facilities with an integrated laboratory central database. Via the central laboratory database

• - the required patient and examination data a detection module of a data input device the commissioning treatment facility is recorded and Coordinates with the state via the laboratory central database own laboratory or laboratory area via data output device in the commissioned laboratory or laboratory area avi siert,  
• - The samples to be examined are in the treatment directions about the acquisition modules according to given Criteria marked and / or coded and to the delivered to a permanent laboratory or laboratory area,
• - the pre-booked investigation orders with Arrival of the samples in the laboratory or laboratory area fourth and
• - the examination data after completion of the examination stored in the laboratory central database and via Data transmission facilities to the ordering Be action facility transmitted.

The client requests the determination of Parameters. In order to be able to determine these parameters, the laboratory must carry out examinations on the Pro make materials. The samples are from the Ma distribution of materials to the respective laboratory location. Here it is checked in as available. The Untersu The client will then receive the result communicated via data transfer.

In particular, the workflow is fol to the extent:

Every commissioning station or every commissioning station Medical practice has a registration module that works with the laboratory central database is networked in the laboratory. At Order triggering will be the necessary patient and Order data entered on the registration module. This includes ren: Client, patient, all to be tested matching parameters, if necessary also those for determining the these parameters necessary examinations and devices, at de the examinations are to be carried out. From capturing data module are transferred to the laboratory. There are also direct ISDN connections, WAN connections  via ISDN, Internet connection or email. At the same time, the Eti chains printed. In addition, comments can be made here conditions for preanalytics, completion date u. Ä. be included. Preanalysis is the treatment of Samples before examination. That can affect the pure storage of the samples or on their preparation for the following tests.

The request module recognizes after entering Ver thought diagnoses or diagnoses according to the classification lCD 9 and lCD 10 (International Criteria of disease) stored laboratory diagnostic guidelines and strikes standard according to main and secondary diagnoses based requirement behavior of laboratory tests in front. This leads to a verifiable process fixed quality standard in prevention and Disease detection. Not with the chosen Er disease-induced analyzes are avoided. For the Prevention, diagnosis and therapy absolutely necessary Analyzes are not forgotten. This continues Patient identification system the function of Check yourself at a set interval changed laboratory results. The requester is about already known results, even if he was not the initiator of the analyzes. Findings everyone is therefore "online" for co-treatment participating medical institution for Available.

The acquisition module expediently runs on an IBM-kom patible PC. Documents accompanying the order can be found at be scanned for example.  

After entering the order can be confirmed immediately or be deferred. Deferred orders are collected in a job queue and can be confirmed later. If necessary, another laboratory can be selected that can take on the job. Appropriately he label printing only follows after the order confirmation supply, so that all laboratory data are taken into account can be.

The laboratory activates the when the material arrives pre-booked order. Samples, e.g. B. for a clinical or hematological laboratory can be directed directly to the appropriate laboratory space become.

A sample is required to be checked in to the laboratory just held the label in front of a barcode reader to what the data associated with the sample is based on be displayed on a monitor.

The transferred patient data are transferred to a patient identification module. This module can return several results:

• - If the patient has been clearly identified, the Order processed immediately.
• - If no patient has been identified, they will be The patient data contained in the contract are complete checked. If the data is sufficient, a new patient record created and the order processed immediately. If the data are not sufficient accordingly, there is a message so that first a individual data acquisition in the laboratory, e.g. B. after te telephone demand, must be made.

After the investigations have been carried out, the results nisse to the communication system and one Subjected to delta check. During the delta check, the ge measured value with the patient's previous value, the norm value range and / or a fixed technical limit compared. If errors occur, they will occur special jobs processed immediately. Under Um can automatically stand during the delta check Follow-up examination can be scheduled. All results, which, on the other hand, are in a release area Approved. Some results also require medical validation by a specialist doctor.

The laboratory doctor should do this via the communication system Have access to the patient's medical record because the Medical history of the patient important infomatio about the possible diagnosis and the treatment path tegie delivers. At least data on diagnoses, Medicines and chronic diseases of the patient be accessible.

The examination result expediently contains an edi animal part into which the laboratory doctor inserts comments can.

For some parameters, the result is ei an investigation decided whether and which other Investigations are necessary, which may then automatically can be set on the table.

Some diseases are reportable by law. Becomes such a disease of a patient in the laboratory reports to the health department and to the attending doctor. The same applies to  highly infectious germs. If these are proven, he follows a message to the ward or doctor to order to be able to initiate preventive measures.

The data transmission from the laboratory central database follows via email, network printer, fax or LDT. The About Transfer via LDT should be attached to an email or di can be made directly via ISDN. It can too several transmission paths can be provided in parallel. All transmissions of the findings are appropriately logged. The time, laboratory area, Type of finding u. Ä. are recorded.

An indivi duelle findings layout are defined, in which z. B. a certain order and arrangement of the findings pa rameter is selected.

The communication system has the advantage that both the requester as well as the laboratory always have a current one Overview of the status of upcoming, activated and have finished inspection orders and accordingly can react in time. With material problems can be traded close to the patient.

The database responds to critical investigators results after appropriate technical approval auto automatic, reports immediately to the laboratory requester and may initiate further investigations. Together can be a complex subject with the clinically active colleague Find across locations on the screen, if necessary immediately bar at the patient bed.  

Repeat examinations are avoided. The sy stem also helps the flood of information and the to minimize costs associated with their control.

All data are stored centrally and stand for Follow-up examinations and presentation of the disease history, possibly also for others than the original Client, available.

A warehouse management module is integrated in the system, the consumables per examination and Reagents "debited" and the delivery of the Ar workplace on the management of minimum storage managed according to workplaces. Network-wide order volume and order height discounts can be opti managed. In addition, the Mon dul supplying the laboratory requester with blood draw measuring systems and other aids. The delivery the station is done by checking in the materials per sender. In this way, movement data can be automatically generated be witnessed and the inventory at the client be determined.
