Due to the introduction of a variety of new features to the German health system, such as a new reimbursement system for inpatient work based on diagnosis-related groups, an obligation to detailed documentation for total quality management, as well as due to the continuing increase in the amount of imaging and other data within invasive cardiology, the use of electronic databases for documentation in the cardiac cath lab is of significant importance. The user friendliness and robustness of the software system for daily clinical practice is crucial for the acceptance of electronic documentation systems by physicians, nurses and technicians. This survey was aimed to explore the current practice and experiences of German cardiac catheterization labs with electronic databases particularly designed for documentation in invasive cardiology, including report generation of cath studies, risk and complication management and logistics for medical material ordering for the cath lab. Of the 176 hospitals and practices having agreed in taking part in this surveillance 165, are currently using an electronic database for administration of medical data and study reports. In 64% of the cath labs, a sub-specialized software system for detailed documentation of the course and the results of an invasive procedure, the human and material resources used, generation of the cath report, and documentation of procedural and post-procedural complications for total quality management is used. The acceptance and satisfaction with the software solutions currently available reveals to be rather inhomogeneous. While user-friendliness and flexibility of a number of software products were positively mentioned, main issues, such as missing hardware of software interfaces with the hospital information system for patient administration, missing stability of several systems, image management too complex and report configuration too inconvenient for daily clinical practice, were criticized. In general, in the light of continuing increase of the amount of clinical and imaging data as well as due to the legal obligation of detailed procedural documentation in all areas of invasive cardiology, a documentation system based on electronic databases bears the potential of an enormous economization of the daily workload of a cardiac cath lab. Prerequisites for the acceptance of such a system in clinical practice is not only the stability and reliability of the system but also the ability to link such a sub-system to existing databases via suitable interfaces and the flexibility of the system for modification of its features to meet the individual requirements of each user.
