NEXUS / OIM: the oncology information system

NEXUS / OIM provides a simple, user-friendly and secure oncology information system, aimed specifically at the needs of facilities in the field of radiation therapy. The solution can be modified flexibly in line with your individual requirements.


The treatment of radiotherapy patients is characterised by a large amount of different information, all of which must be collected and processed. Patient medical records, external records, complex radiation treatment plans and diagnostic images must be clearly documented. The treatment process and the interdisciplinary cooperation of physicians, physicists, chemotherapists and surgeons must be planned and coordinated effectively. In addition, large amounts of data are supplied by medical devices, and this data must be stored efficiently and safely. Media and system interruption points make it difficult to gain a quick and clear overview of all information and can compromise optimum patient treatment.


The fully integrated solution NEXUS / OIM provides the ideal basis for processing all relevant data in a radio-oncological treatment in a vendor-independent radiotherapy information system. Daily work activities in oncology are effectively supported by NEXUS / OIM and the treatment for patients is improved.

All information at a glance

The electronic patient record is the central component of the NEXUS / OIM oncology solution. All treatment-related information is documented here. Likewise, examination orders for imaging, lab orders, etc. are created directly in the electronic patient file and sent to the PACS or lab systems. Test results are automatically stored and information on the organisation of the treatment process can be viewed directly. The electronic patient record therefore becomes central information hub for oncology.

The most important elements:
  • Patient overview with the most important information on the treatment.
  • A detailed description of all diagnostic-relevant aspects, classifications, physical examinations and planned therapies.
  • In the description of EBRT and brachytherapy, the medical prescription and the result of the radiation therapy planning are combined, taking into account the organs at risk.
  • Chemotherapy schedules are stored on the system for preparing and carrying out chemotherapy treatments. The work of all involved occupational groups (doctors, pharmacy, nursing) is supported efficiently.
  • Corresponding templates are available for nuclear medicine treatment.
  • NEXUS / OIM is constantly being further developed for   the application of new forms of therapy such as IORT (Intraoperative Radiotherapy) or HIFU (High Frequency Ultrasound).
  • To be able to map the entire treatment process in the electronic patient record, the treatment protocols are transferred via the HL7 interface from the respective record-and-verify systems and displayed directly in the NEXUS / OIM.


In addition to specific oncology modules of the electronic patient file, forms are available for storing scanned documents, reports, letters and orders to the imaging system.

Advantages at a glance:
  • All patient information at a glance
  • Documentation of the entire treatment history
  • Manufacturer-independent data exchange with treatment devices
  • Simplification of lab requirements
  • Multimedia documentation of the entire treatment


Managing appointments and handling processes

The increasing requirements for fast and transparent communication in connection with paperless workflows are covered by the use of a flexible workflow module. Freely definable work lists provide a quick overview of the status of orders, open tasks etc.



Scheduling and resource planning in NEXUS / OIM provides a complete overview of all appointments for an oncology clinic. Scheduling includes doctors appointments  as  well as appointments for diagnostics and therapy. These are planned directly or created from workflow orders using drag-and-drop. Availability conflicts with patients, staff or equipment are avoided with the help of the OIM scheduler as this continually synchronises with all existing appointments.


Therapy appointments can be created in the scheduler or transferred directly from the therapy system. Special planning procedures such as regular appointments, appointment profiles or the planning of hyperfractionations facilitate time- based coordination in radio-oncological therapy planning.


Thanks to the integrated status management, the execution of appointments across multiple phases can be viewed clinic-wide.


In activity recording, predefined activity points can be directly recorded and transferred to billing. All required data for the preparation of DICOM modality worklists or for sending requests via HL7 can be automatically derived from the OIM scheduler.


Workflow functions

Orders can be sent, received, tracked and processed in the NEXUS / OIM workflow module. It is also possible to specify appointments in the OIM scheduler directly from the order. Associated elements of the patient record are always linked and can be viewed without detours.


Process loops can also be mapped via a special process level.


Typical processes with workflow support are:

  • Admission workflow
  • Order workflow
  • Workflow for letter-writing


Advantages at a glance:
  • Current and rapid overview of all resources
  • Continual clash checking of all appointments
  • Standard interfaces for import / export of appointments
  • DICOM Modality Worklist
  • All workflows managed in one system
  • Transparent overview of the processing status of



Support modules: highly flexible and accurate

For the use of OIM in oncology facilities, NEXUS offers a variety of modules from the NEXUS / HIS. These modules are highly configurable and offer great flexibility when used in different application scenarios. In this way, OIM benefits from many years of experience with the development and integration of medical information systems.


A special focus is the combination of data and functions for the implementation of customer-specific processes. Through “one-click-to-information”, users are guided step by step through predefined workflows.


Progress notes module

In addition to the therapy documentation, NEXUS / OIM also includes a module for the capturing of progress notes that supports the interdisciplinary work of doctors, therapists and nurses. In addition to manually recorded entries, important information such as findings or information on medication and care management are automatically transferred to the progress notes module.


Patient management

NEXUS / OIM offers a separate module for patient registration and recording related data. Patient management can be adapted to country-specific requirements. Alternatively, patient data can be taken from existing hospital information systems.


Lab data

For the integration of laboratory systems, NEXUS / OIM offers a module for requesting lab tests as well as for displaying the lab results. Lab labels can be printed directly from within the system. An integrated status monitor provides information at all times on open and completed lab tests.


The laboratory values taken from the lab information system are displayed in an integrated laboratory data viewer.


Service recording

The integrated Charge Capture module enables the capture of any service items based on tariff-neutral services. Here, preliminary information from   scheduling,   documentation or interfaces is used to derive service items automatically. NEXUS / OIM provides its own billing system for Germany, Austria and Switzerland. HL7 and SAP interfaces enable the transfer of service data to external billing systems.


Letter generation

An integrated letter-writing tool enables the automatic creation of predefined reports using data from the electronic patient records. The correction and consignment process is supported by the workflow module and the option to send   a message directly by e-mail or fax.


Advantages at a glance:
  • Available modules for a wide range of clinical processes
  • One-click-to-information: All modules are fully interlinked
  • Flexible, customer-specific adaptation
  • Automated letter-writing
  • Simplified billing functions


OIM PACS: Easy picture management incl. RT-VIEW

The NEXUS / PACS covers the entire spectrum of medical multimedia communication, storage and diagnosis across institutions.


In addition to the high-performance DICOM archive, the OIM PACS also offers high-end and web viewers as well as special viewers for displaying RT plan files. Functionalities for importing images are also available, as are telemedicine modules for rapid image transfer or for forwarding images to other attendants or follow-up medical staff.


Optimum care on ward and outpatient

The NEXUS / OIM care management supports all clinical care processes and thus the communication and task management between nurses and doctors.


Care management covers the following tasks:

  • Regulation and implementation of care measures
  • Delivery of prescribed medication
  • Care documentation with status and care assessments
  • Standardised progress documentation
  • Ward management with order and bed management


NEXUS / OIM care management follows a universal approach for mapping different nursing models.



The medication module enables the implementation of continuous electronic medication from the prescription to the administration. The regulations for unit-dose medication are covered as well as for infusions. The delivery of prescribed drugs can be carried out via a delivery list or alternatively via the ward chart.





Great all-round care

The optimal care of oncological patients on the ward places high demands on care management and on the communication between nursing staff and doctors. NEXUS / OIM supports nurses in care planning, the provision of medication and wound documentation. In addition, organisational tasks such as bed planning, food ordering and service recording are covered.


Ward chart

The NEXUS ward chart is an integrated module that permits the simple recording and visualising of vital signs, fluid balance and data from the medication and care management modules. In addition, the ward chart can be individually expanded with other components as needed, e.g. catheters and drains, ventilation and scores. The ward chart allows the direct processing of drugs and care without detour via the appropriate modules.


Ward management

Bed management from NEXUS consists of the bed planning and ward overview modules. Bed planning permits the long-term occupancy planning of the ward beds and controls the associated procedures in patient administration. The ward overview is used for the coordination of the current assignments.


Bed overview

The OIM bed overview provides a quick overview of the occupancy situation of a ward. Patients can be relocated within a ward using drag-and-drop. Transfer to other wards is dialogue-controlled.


Bed planning

First, a temporary bed allocation is carried out for patients in the planning phase and at registration. The actual assignment of beds is fixed during the admission of patients. The individual steps are distinguished graphically and by colour. Patients without a bed allocation can be included in the planning using what are known as “corridor beds”. In the event of bottlenecks, extra beds can be displayed and assigned for each ward.


Advantages at a glance:
  • Overview of medical and nursing information in a time-based context
  • Digital bed management with graphic display of the assigned and free beds
  • Very easy assignment using drag-and-drop



The data hub

The NEXUS / INTEGRATION SERVER is the central element for data exchange between NEXUS / OIM and connected medical devices or peripheral systems such as Mosiaq, ARIA and laboratory systems. The integration server documents the data transfer and gives the system administrator a transparent overview of the entire data traffic. Data transfer analysis and automatic notification capabilities for interface issues make it easy to monitor overall system communication.
