Cross-institutional data exchange using the clinical document architecture (CDA).

PROBLEM: Although electronic communication of clinical data between various actors in the healthcare domain seems crucial for a cost-effective patient treatment, it is mostly restricted to paper based documents. In order to meet the growing need for improved data communication, it is necessary to overcome the barriers of software heterogeneity and lack of standards, especially in cross-institutional shared care communication. HL7's clinical document architecture (CDA) is a new and promising tool to exchange any clinical document. In this paper we show how CDA can be used to (1) share electronic discharge letters and other clinical data generated and stored in the hospitals electronic patient record (EPR) with general practitioners and (2) to transfer these clinical data to a personal electronic health record (EHR). The latter scenario is in routine use. Ease-of-use and data security and integrity were the main design principles in both scenarios. METHODS: Within the electronic patient record a data extraction and exporting mechanism has been built. For both scenarios appropriate data processing and transmission methods have been developed, and the receiving information systems have been prepared for the CDA based data input. RESULTS: Although there still remain technical and organizational issues to be solved, this is a promising method in order to enhance data exchange between hospital and primary care and to move towards an electronic patient record (EPR) and an electronic health record (EHR) crossing institutional borders. This paper describes the design and current implementation and discusses our experiences.

The diagnosis related groups enhanced electronic medical record.

PROBLEM: The introduction of Diagnosis Related Groups as a basis for hospital payment in Germany announced essential changes in the hospital reimbursement practice. A hospital's economical survival will depend vitally on the accuracy and completeness of the documentation of DRG relevant data like diagnosis and procedure codes. In order to enhance physicians' coding compliance, an easy-to-use interface integrating coding tasks seamlessly into clinical routine had to be developed. A generic approach should access coding and clinical guidelines from different information sources. METHODS: Within the Electronic Medical Record (EMR) a user interface ('DRG Control Center') for all DRG relevant clinical and administrative data has been built. A comprehensive DRG-related web site gives online access to DRG grouping software and an electronic coding expert. Both components are linked together using an application supporting bi-directional communication. Other web based services like a guideline search engine can be integrated as well. RESULTS: With the proposed method, the clinician gains quick access to context sensitive clinical guidelines for appropriate treatment of his/her patient and administrative guidelines for the adequate coding of the diagnoses and procedures. This paper describes the design and current implementation and discusses our experiences.
