Impact of a Protocol Processing system (ProtoVIEW) on clinical behaviour of residents and treatment.
International journal of bio-medical computing, 1996Co-Authors: M C Vissers, A Hasman, C J Van Der LindenAbstract:A Protocol Processing system (ProtoVIEW), containing therapeutic trauma Protocols, was used in the Accident and Emergency (A and E) department for a period of 7 months to investigate the impact of automated Protocols on firstly, medical decision making of physicians and secondly, on quality of treatments eventually received by the patients. A randomized controlled trial showed that mandatory use of the system led to a more uniform working strategy while fracture treatment only seemed to improve in a subgroup of patient for whom residents established a correct diagnosis.

Protocol Processing system (Proto VIEW) to support residents at the emergency ward
Computer Methods and Programs in Biomedicine, 1995Co-Authors: M C Vissers, A Hasman, C J Van Der LindenAbstract:This paper describes the design, implementation and evaluation of a prototype Protocol Processing system (ProtoVIEW). ProtoVIEW provides Protocol information for diagnostic and therapeutic purposes. The developed system described here is used as a research instrument to investigate the impact of automated Protocols on the medical decision making of physicians. A first evaluation indicates that residents like to use the system and that usage of the system leads to a more uniform working strategy.

Consultation behaviour of residents supported with a Protocol Processing system (ProtoVIEW) at the emergency ward
International journal of bio-medical computing, 1995Co-Authors: M C Vissers, A Hasman, Cees J.v.d. LindenAbstract:We evaluated the consultation behaviour of residents using a Protocol Processing system in routine clinical practice. A total of 125 consecutive patients, of age 16 years or older with an isolated fracture without concomitant lesions, were treated with computer support between 13 October 1992 and 9 June 1993. All eight surgical residents who worked at the emergency ward of the University Hospital in Nijmegen, The Netherlands participated. The mean consultancy time, method of information retrieval, number of correct Protocols found, number of windows retrieved and attitude towards ProtoVIEW as a useful information source were estimated. Main results are: a mean consultancy time of 1.5 min per case, residents browsed through the Protocol information more often than using keyword search. The correct Protocols were found in 98% of the cases while on average a minimum number of text-browse windows was retrieved. Residents were positive about the way Protocols were presented and about the information supplied by ProtoVIEW. From this study we may conclude that ProtoVIEW consultation is hardly time consuming, and easy to use. Since keyword search was hardly used, expanding the number of synonyms may stimulate searching by keyword more often.

Protocol-Processing overhead on the performance of error recovery schemes in high-speed network environments
1991Co-Authors: Jaime Jungok Bae, Tatsuya Suda, Naoya WatanabeAbstract:Author(s): Bae, Jaime Jungok; Suda, Tatsuya; Watanabe, Naoya | Abstract: This paper investigates the effects of Protocol-Processing overhead on the performance of error recovery schemes in high-speed network environments. The investigated error recovery schemes are:• an edge-to-edge error recovery scheme, where retransmissions of erred packets only take place between source and destination nodes, and• a link-by-link error recovery scheme, where retransmissions only take place between adjacent switching nodes.For retransmission of erred packets, we consider both Go-Back-N and Selective-Repeat procedures in the analysis.The performance measures we obtain are the distribution of transfer delays and the loss probability of packets across a network. To obtain these measures, this paper develops a tandem queueing network model with feedbacks where each queue represents a Protocol layer within a switching node, rather than a switching node as a whole.Numerical results show that for a network with very-high-speed/low-error-rate channels, an edge-to-edge scheme gives the smaller packet transmission delay than a link-by-link scheme for both Go-back-N and Selective-Repeat retransmission procedures, while keeping the packet loss probability sufficiently small.

Evaluation of the effects of Protocol Processing overhead in error recovery schemes for a high-speed packet switched network: link-by-link versus edge-to-edge schemes
IEEE Journal on Selected Areas in Communications, 1991Co-Authors: Jaime Jungok Bae, Tatsuya Suda, Naoya WatanabeAbstract:The authors investigate the effects of Protocol Processing overhead on the performance of error recovery schemes. The focus is on the edge-to-edge error recovery scheme, in which retransmissions of erred packets only take place between source and destination nodes. An approximation is obtained for the Laplace transform for the distribution of the end-to-end packet transfer delay, considering the Processing time required for error recovery. The performance of the link-by-link error recovery scheme, in which retransmissions take place between adjacent nodes, is evaluated and compared to the performance of the edge-to-edge scheme. Numerical results from a tandem queuing network model show that for a network with very-high-speed/low-error-rate channels, an edge-to-edge scheme gives a smaller packet transmission delay than a link-by-link scheme for both go-back-N and selective-repeat retransmission procedures, while keeping the packet loss probability sufficiently small. >
