SAP and partners: IS-H and IS-H* MED.

OBJECTIVES: The Styrian Hospital Organization with 21 hospitals including the Graz University Hospital, and the Heidelberg University Hospital implemented a new HIS based on SAP/R3, ISH, ISH* MED with the objective to have an integrated system to support patient administration and management, patient care, clinical documentation, research etc. METHODS: Heidelberg University Hospital chose a step by step method for the introduction of the system, beginning with patient administration (ISH) and proceeding with clinical functions (ISH* MED). In Styria, the full functionality was implemented--as part of the selection process--in one peripheral hospital and in the Ear, Nose and Throat (ENT) Department of the Graz University Hospital, including special documents to support the processes in the highly specialized ENTunits. RESULTS AND CONCLUSIONS: The standard modules are performant, stable and basically well accepted. Particularly in Graz, it has been shown that the requirements of highly specialized departments for work flow management, documentation and integration of subsystems and data from different sources can be fulfilled by special documents and programs--although at the expense of additional workload particularly in the initial phases of such a project.

Electronic signature for medical documents--integration and evaluation of a public key infrastructure in hospitals.

OBJECTIVES: Our objectives were to determine the user-oriented and legal requirements for a Public Key Infrastructure (PKI) for electronic signatures for medical documents, and to translate these requirements into a general model for a signature system. A prototype of this model was then implemented and evaluated in clinical routine use. METHODS: Analyses of documents, processes, interviews, observations, and of the available literature supplied the foundations for the development of the signature system model. Eight participants of the Department of Dermatology of the Heidelberg University Medical Center evaluated the implemented prototype from December 2000 to January 2001, during the course of an intervention study. By means of questionnaires, interviews, observations and database analyses, the usefulness and user acceptance of the electronic signature and its integration into electronic discharge letters were established. RESULTS: Since the major part of medical documents generated in a hospital are signature-relevant, they will require electronic signatures in the future. A PKI must meet the multitude of responsibilities and security needs required in a hospital. Also, the signature functionality must be integrated directly into the workflow surrounding document creation. A developed signature model, fulfilling user-oriented and legal requirements, was implemented using hard and software components that conform to the German Signature Law. It was integrated into the existing hospital information system of the Heidelberg University Medical Center. At the end of the intervention study, the average acceptance scores achieved were mean = 3.90; SD = 0.42 on a scale of 1 (very negative attitude) to 5 (very positive attitude) for the electronic signature procedure. Acceptance of the integration into computer-supported discharge letter writing reached mean = 3.91; SD = 0.47. On average, the discharge letters were completed 7.18 days earlier. CONCLUSION: The electronic signature is indispensable for the further development of electronic patient records. Application-independent hard and software components, in accordance with the signature law, must be integrated into electronic patient records, and provided to certification services using standardized interfaces. Signature-oriented workflow and document management components are essential for user acceptance in routine clinical use.

Using the eXtensible Markup Language (XML) in a regional electronic patient record for patients with malignant diseases.

Communication between different institutions which are responsible for the treatment of the same patient is of outstanding significance, especially in the field of tumor diseases. Regional electronic patient records could support the co-operation of different institutions by providing ac-cess to all necessary information whether it belongs to the own institution or to a partner. The Department of Medical Informatics, University of Heidelberg is performing a project in co-operation with the Thoraxclinic-Heidelberg and the Department of Clinical Radiology, University of Heidelberg with the goal: to define an architectural concept for interlinking the electronic patient record of the two clinical institutions to build a common virtual electronic patient record and carry out an exemplary implementation, to examine composition, structure and content of medical documents for tumor patients with the aim of defining an XML-based markup language allowing summarizing overviews and suitable granularities, and to integrate clinical practice guidelines and other external knowledge with the electronic patient record using XML-technologies to support the physician in the daily decision process. This paper will show, how a regional electronic patient record could be built on an architectural level and describe elementary steps towards a on content-oriented structuring of medical records.

[Clinical archiving--requirements and current solutions].

In this paper we summarize requirements for archiving in hospitals. Furthermore, we present solutions how digital archives can be built up. Archiving in hospitals requires medical documentation, which should take place preferably in a computer-based way. Requirements for electronic archiving include functionality, integration into the hospital information system, robustness, performance, usability and the ability to meet legal obligations. The latter issue is essential if the conventional archiving of paper records and non-digital images shall be abandoned.

On stepwise integrating an electronic patient record based on digital-optical archiving and multi-purpose health professional workstations: experiences at the Heidelberg University Hospital.

At the Heidelberg University Hospital the conventional paper-based medical record is currently being replaced by a "unique" electronic patient record (EPR). This paper describes the stepwise integration of an EPR based on digital-optical archiving and multi-purpose health professional workstations. If focuses on the potentials of digital optical archiving as an integral part of hospital information systems. So far, the EPR has been introduced in the central archive of the "head clinic", the Neurosurgical Clinic and the inpatient archive, the endoscopy and sonography section of the Department of Internal Medicine.

Health professional workstations and their integration in a hospital information system: the pragmatic approach MEDIAS.

Within the daily workload at a ward there is a considerable amount of information processing. It is the task of a systematic management of hospital information systems to provide health professionals with the right information in the right place at the right time. This paper deals with the consequences for the management of hospital information systems if health professional workstations are introduced as a means for this information logistic and with the experiences gained in the Heidelberg University Hospital. Health professional workstations are formally defined in the context of a three level graph-based model of hospital information systems. It is found that health professional workstations have communication needs not only on the physical level of computer systems in the hospital information system but also on the logical tool level, which is the level of application systems. On this level communication servers or brokers are of considerable importance. In Heidelberg there are about 200 health professional workstations (MEDIAS) in routine use.

Pulmonary hamartoma.

From 1973 to 1980, 9 pulmonary chondromatous hamartomas of the lung were resected at our Clinic. One of these hamartomas was a rare endobronchial chondroma. To our knowledge, 91 cases of endobronchial hamartomas have been described in the previous literature. Although a similar origin of intrapulmonary and endobronchial hamartomas is postulated, there is a difference in their clinical features. The endobronchial type of hamartoma often causes respiratory symptoms of obstructing the bronchus with consequent destruction of the distal lung, whereas patients with intra-pulmonary hamartomas are symptom-free.
