Abstract Modern surgical departments are characterized by a high degree of automation supporting complex procedures. It recently became apparent that integrated operating rooms can improve the quality of care, simplify clinical workflows, and mitigate equipment-related incidents and human errors. Particularly using computer assistance based on data from integrated surgical devices is a promising opportunity. However, the lack of manufacturer-independent interoperability often prevents the deployment of collaborative assistive systems. The German flagship project OR.NET has therefore developed, implemented, validated, and standardized concepts for open medical device interoperability. This paper describes the universal OR.NET interoperability concept enabling a safe and dynamic manufacturer-independent interconnection of point-of-care (PoC) medical devices in the operating room and the whole clinic. It is based on a protocol specifically addressing the requirements of device-to-device communication, yet also provides solutions for connecting the clinical information technology (IT) infrastructure. We present the concept of a service-oriented medical device architecture (SOMDA) as well as an introduction to the technical specification implementing the SOMDA paradigm, currently being standardized within the IEEE 11073 service-oriented device connectivity (SDC) series. In addition, the Session concept is introduced as a key enabler for safe device interconnection in highly dynamic ensembles of networked medical devices; and finally, some security aspects of a SOMDA are discussed.

AbstractThe new medical device communication protocol known as IEEE 11073 SDC is well-suited for the integration of (surgical) point-of-care devices, so are the established Health Level Seven (HL7) V2 and Digital Imaging and Communications in Medicine (DICOM) standards for the communication of systems in the clinical IT infrastructure (CITI). An integrated operating room (OR) and other integrated clinical environments, however, need interoperability between both domains to fully unfold their potential for improving the quality of care as well as clinical workflows. This work thus presents concepts for the propagation of clinical and administrative data to medical devices, physiologic measurements and device parameters to clinical IT systems, as well as image and multimedia content in both directions. Prototypical implementations of the derived components have proven to integrate well with systems of networked medical devices and with the CITI, effectively connecting these heterogeneous domains. Our qualitative evaluation indicates that the interoperability concepts are suitable to be integrated into clinical workflows and are expected to benefit patients and clinicians alike. The upcoming HL7 Fast Healthcare Interoperability Resources (FHIR) communication standard will likely change the domain of clinical IT significantly. A straightforward mapping to its resource model thus ensures the tenability of these concepts despite a foreseeable change in demand and requirements.

Abstract Today’s landscape of medical devices is dominated by stand-alone systems and proprietary interfaces lacking cross-vendor interoperability. This complicates or even impedes the innovation of novel, intelligent assistance systems relying on the collaboration of medical devices. Emerging approaches use the service-oriented architecture (SOA) paradigm based on Internet protocol (IP) to enable communication between medical devices. While this works well for scenarios with no or only soft timing constraints, the underlying best-effort communication scheme is insufficient for time critical data. Real-time (RT) networks are able to reliably guarantee fixed latency boundaries, for example, by using time division multiple access (TDMA) communication patterns. However, deterministic RT networks come with their own limitations such as tedious, inflexible configuration and a more restricted bandwidth allocation. In this contribution we overcome the drawbacks of both approaches by describing and implementing mechanisms that allow the two networks to interact. We introduce the first implementation of a medical device network that offers hard RT guarantees for control and sensor data and integrates into SOA networks. Based on two application examples we show how the flexibility of SOA networks and the reliability of RT networks can be combined to achieve an open network infrastructure for medical devices in the operating room (OR).

Rest Api

Abstrak: Semakin berkembang perusahaan apalagi instansi kesehatan maka di butuhkan lebih banyak pegawai yang dibutuhkan untuk menunjang kegiatannya, akan tetapi pihak manajemen seringkali kesulitan untuk menentukan penambahan pegawai dikarenakan harus mempertimbangkan upah, karir dan kesejahteraan dari pegawai yang akan direkrut. Untuk itu diperlukan sistem informasi untuk mendukung kebutuhan pelayanan agar keterbatasan tenaga tidak menjadi penghambat pekerjaan dan mutu pada instansi kesehatan terutama pada rumah sakit. Meskipun sudah ada sistem informasi terkadang instansi kesehatan memiliki sistem informasi lebih dari satu. Hal itu tidaklah efektif dalam hal pelayanan terutama pada pemeriksaan laboratorium hal itu rentan terjadinya human error pada saat pengisian nilai hasil laboratorium dan waktu pelayanan yang lama karena harus input dua kali pada sistem informasi. Maka dari itu penulis membangun sebuah Rest-Api yang dapat mengintergrasikan kedua sistem informasi tersebut. Kedua sistem tersebut adalah sistem informasi manajemen rumah sakit (SIMRS) dengan sistem informasi laboratorium (LIS) dengan menggunakan metode Service Oriented Architecture (SOA). Untuk pengujiannya sendiri penulis menggunakan metode grey box testing. Dengan adanya integrasi kedua sistem tersebut diharapkan dapat meminimalisir terjadinya human error dan waktu pelayanan yang lama pada laboratorium. Hasil yang diujikan terdapat error ketika ada data yang salah diinput kemudian tidak terbaca pada SIMRS. Hal tersebut dapat di atasi dengan maping ulang antara kode pemeriksaan yang ada pada SIMRS dengan LIS sehingga minim terjadi error pada saat mengirim hasil pemeriksaan dari LIS ke SIMRS.   Kata kunci: integrasi sistem, laboratorium, Sistem Informasi Laboratorium, Sistem Informasi Rumah Sakit, rumah sakit.   Abstract: The more developed the company, especially the health agency, the more employees are needed to support its activities, but the management often finds it difficult to determine the addition of employees because they have to consider the wages, careers, and welfare of the employees to be recruited. For this reason, an information system is needed to support service needs so that limited manpower does not become an obstacle to work and quality in health agencies, especially in hospitals. Even though there is already an information system, sometimes health agencies have more than one information system. This is not effective in terms of service, especially in laboratory examinations, it is prone to human errors when filling out laboratory results and long service times because they have to be inputted twice into the information system. Therefore, the author builds a Rest-API which can integrate the two information systems. The two systems are a hospital management information system (SIMRS) and a laboratory information system (LIS) using the Service Oriented Architecture (SOA) method. For the test itself, the author uses the gray box testing method. With the integration of the two systems, it is expected to minimize the occurrence of human errors and long service times in the laboratory. The results tested have an error when there is incorrect data entered and then it is not read on the SIMRS. This can be overcome by re-mapping between the existing inspection codes on SIMRS and LIS so that there are minimal errors when sending inspection results from LIS to SIMRS.   Keywords: system integration, laboratory System, LIS, Hospital System, hospital.

Enterprise Collaboration

Current CAD systems only support interactive geometry generation, which is not ideal for distributed engineering services in enterprise-to-enterprise collaboration with a generic thin-client service-oriented architecture. This paper proposes a new feature-based modeling mechanism, document-driven design, to enable batch mode geometry construction for distributed CAD systems. A semantic feature model is developed to represent informative and communicative design intent. Feature semantics is explicitly captured as trinary relation, which provides good extensibility and prevents semantics loss. Data interoperability between domains is enhanced by schema mapping and multi-resolution semantics. This mechanism aims to enable asynchronous communication in distributed CAD environments with case of design alternative evaluation and reuse, reduced human errors, and improved system throughput and utilization.
