[PC-assisted planning and documentation of the surgical schedule].
A computer program for personal computers was developed to support and control the schedule in the operation theatre. With this program a great amount of operational and medical data will be recorded (e.g. the duration of operation and anesthesia, the number of operating rooms occupied, the personnel involved, the diagnosis and surgical therapy). The screen shows up-to-date information about the ongoing events. All data can be easily evaluated for different criteria. In a four years period the program presented has proved valuable for daily routine planning and documentation in a great operation unit.

[A UNIX-based electronic data processing system for routine use in a trauma surgery department].
A computer program for a UNIX workstation has been developed to support routine activities in a surgical department. A relational database contains reports on operations, medical letters and further data imported from independent computer subsystems outside the department. Data are accessible at 15 terminals and PCs through a simple and intuitive user interface with a mouse. The patient record is organized in a hypertext fashion and permits direct access to the various types of documents in a consistent manner. The implementation is currently used to manage information on 40,000 patients and has proved valuable in daily routine over a 2-year period.

[Computer-assisted documentation of mandibular fractures].
For the registration, documentation and evaluation of patient data in cranio-maxillo-facial (cmf) trauma surgery a Windows-based application front end for relational data base systems (RDBS) has been developed. A simple-to-learn, easily reconfigurable user interface can be adjusted to the dynamically changing needs of individual departments. A graphical user interface (GUI) eases the entry of complex information like fracture positions, the location of implanted osteosynthesis material, etc. The new program also simplifies the daily routine documentation tasks. Being linked to a Hospital Information System (HIS) it makes use of the patients' individual base data stored there. Statistical data for various studies can be extracted from the database. The program has been successfully tested on a collective of 1.178 cmf trauma patients. Predefined analyses can be generated now by the simple click of a button for various case selections. New users learn to operate the program in a very short time.

[Teleconference and telesurgery].
Interchange of information has become possible independent of the user's place or time by modern telemedical services and opens up new dimensions for diagnostic and therapeutic procedures. For teleconferences and teleconsultations in surgery, the intraoperative high-quality transmission of live images is essential without disturbing the sterility and operation routine. The clinical specifications require special systems for broadband, stereoscopic online image transmission both intra- and inter-institutionally. Moreover, a telemedical concept integrates the communication equipment suitable for the different diagnostic and functional facilities of a clinic, a digital multimedia patient record and modules for cooperative working. These implementations are a prerequisite for extensive telesurgical interventions using navigational tools, guided instruments or autonomous roboter systems. The realization of such a comprehensive telesurgical concept (OP 2000) is presented.

[Computer-assisted surgery documentation in clinical routine practice].
In surgery, computer support is still of minor importance. It is the aim of this publication to outline the concept of a computer-assisted documentation system for surgical procedures, to describe the realization of the concept and to discuss the results of the evaluation. Planning of the system started in 1988 with an analysis of existing computer support at our clinic, definition of the parameters to be documented and determination of the classifications to be used, followed by a design for the system's use and a decision on hardware and software. The system is run on an IBM-compatible personal computer with three terminals, and the software used is MEDOS. The surgical procedures are documented with a four-level hierarchical classification related to the VESKA code and the internal university codes. After extensive training of the doctors, routine use commenced in 1991. Up to now 9837 operations have been documented by 35 surgeons. The system produces all necessary statistics and supports scientific studies and inquiries from individual doctors. A prospective evaluation of 300 consecutive operations demonstrated good compliance of the doctors and high data quality. To achieve optimal benefit from the use of computers it is recommended that departmental communication and documentation systems be gradually built up in surgical departments.

Recognition accuracy with a voice-recognition system designed for anesthesia record keeping.
We tested on three occasions, with anesthetists as subjects, the accuracy of two voice-recognition systems designed for anesthetic record keeping. Initially, a prototype system was tested (10 subjects); several years later the resulting commercial system was tested in a quiet environment (11 subjects) and in noisy operating rooms (10 subjects). For each test an anesthetist first trained the system to recognize his or her voice by reading aloud a list of common anesthetic terms. To determine recognition accuracy, the percentage of words recognized correctly by the computer, each subject repeated the vocabulary words ten times. Although accuracy was similar during the three tests, it was slightly higher with the laboratory test (mean percent of words recognized correctly, 96.5%; range of accuracy for individual anesthetists, 91.6 to 98.8%) than with the prototype test (95.9%; range, 89.1 to 99.6%). Accuracy was lowest with the operating room test (95.3%; range, 87.8 to 98.4%). Twenty-four words caused particular difficulty during the laboratory test and were eliminated from the vocabulary of the subsequent operating room test. Omitting these 24 words from the laboratory vocabulary list allowed a more nearly direct comparison with the results from the operating room list; recognition accuracy improved in the former to 97.5% (range, 92.1 to 98.9%). Two anesthetists--one each from the laboratory and operating room tests--performed poorly, and eliminating their scores changed the respective overall scores to 98.2% (range, 96.7 to 98.9%) and 96.5% (range, 94.3 to 98.4%). Thus, the corrected difference between the laboratory accuracy and the operating room accuracy was 1.7%.(ABSTRACT TRUNCATED AT 250 WORDS)

[The Würzburg Ear Forms: a system to document surgery and follow-up evaluation].
BACKGROUND: About a decade ago a PC based system to document surgery and follow up evaluation was installed. At that time the wide spread DOS systems provided only inputs via the keyboard. However, we believed that to assure the system would be accepted by the user, a graphical user interface would be necessary. Such an interface provides greater user-comfort and ensures the validity of entered data. METHODS: A simple graphical platform was installed, which provided all the necessary functions without being too complex. Several forms were designed for data collection. The first form implemented was designed for ear surgery. It comprises 356 items. The relevant data in the form are selected by a mouse click from possible alternatives. Although a large number of items are provided, it takes only one to two minutes to fill in the form. RESULTS: At present, September 2001, the database contains 10 453 records related to ear operations, 9633 preoperative audiograms and the results from 16 140 follow up evaluations. A special language and an interpreter for analyzing the data were added to complete the system. CONCLUSIONS: The large number of cases stored in the database allows data analysis with a high level of statistical confidence for any conclusions based upon the data. It also allows investigations of the simultaneous influence of a large number of variables on the results.

Advanced telepresence surgery system development.
SRI International is currently developing a prototype remote telepresence surgery system, for the Advanced Research Projects Agency (ARPA), that will bring life-saving surgical care to wounded soldiers in the zone of combat. Remote surgery also has potentially important applications in civilian medicine. In addition, telepresence will find wide medical use in local surgery, in endoscopic, laparoscopic, and microsurgery applications. Key elements of the telepresence technology now being developed for ARPA, including the telepresence surgeon's workstation (TSW) and associated servo control systems, will have direct application to these areas of minimally invasive surgery. The TSW technology will also find use in surgical training, where it will provide an immersive visual and haptic interface for interaction with computer-based anatomical models. In this paper, we discuss our ongoing development of the MEDFAST telesurgery system, focusing on the TSW man-machine interface and its associated servo control electronics.

[IOL and aniseikonia calculation combined with documentation of surgical data and IOL inventory].
The exact recording of operation data is a precondition for keeping the standards high in cataract surgery, but surgeons are reluctant to answer a questionnaire after a strenuous operation. We have designed a program easy to use in the Macintosh Hypercard System that covers all aspects of cataract surgery such as: (1) the operating record; (2) a data sheet for recording the various details of the operation; (3) recording of the data on hard disc; (4) managing the IOL stock list; (5) proposal of IOL models that are in stock with regard to IOL power (SRK2) and aniseiconia. This program enables the surgeon to record the operation data with effortless ease and it is well accepted. There is no dictation. The operating record and data sheet are printed immediately. The program is controlled by a "mouse". Selection of the suitable IOL model is facilitated by the link between the calculation of IOL power and the IOL stock list. In special cases the IOL power can be changed to obtain less aniseiconia.

[Automated anesthesia record keeping system in in the United States].
We have implemented an automated anesthesia record keeping system (AARK) since 1992. The system stands in need of re-designing to function as a perioperative patient's information system. We discussed the issues with anesthesiologists who's institutes are implemented with AARK in the United States. We visited the following three institutes: St. Luke's Hospital (Kansas City, MO), University of Florida (Gainesville, FL), and Burbank Hospital (Fitchburg, MA). All of them are implemented with ARKIVE system. Dr. Edsall in Burbank Hospital stressed quality assurance (QA), and using ARKIVE's database for QA. University of Florida has a big anesthesia and engineering team to develop a new ergonomically sound AARK. Some of the members regarded ARKIVE as an "out of date" system. Dr. Tuohy in St. Luke's Hospital stressed cost/benefit of AARK. Taking their experience into account, we are designing a new perioperative patient's information system including AARK.

[Automated anesthesia record system].
Based on Client/Server architecture, a software of automated anesthesia record system running under Windows operation system and networks has been developed and programmed with Microsoft Visual C++ 6.0, Visual Basic 6.0 and SQL Server. The system can deal with patient's information throughout the anesthesia. It can collect and integrate the data from several kinds of medical equipment such as monitor, infusion pump and anesthesia machine automatically and real-time. After that, the system presents the anesthesia sheets automatically. The record system makes the anesthesia record more accurate and integral and can raise the anesthesiologist's working efficiency.

Influence of the method of data collection on the documentation of blood-pressure readings with an Anesthesia Information Management System (AIMS).
The influence of methods for record keeping on the documentation of vital signs was assessed for the Anesthesia Information Management System (AIMS) NarkoData. We compared manually entered blood-pressure readings with automatically collected data. These data were stored in a data-base and subsequently evaluated and analyzed. The data sets were split into two groups, "manual" and "automatic". We evaluated the effect of automatic data collection on the incidence of corrected data, data validity and data variation. Blood-pressure readings of 37,726 data sets were analyzed. We could assess that the method of documentation did influence the data quality. It could not be assessed whether the incorrectness of data during automatic data gathering was caused by artefacts or by the anesthesiologist.
