Child Health Improvement through Computer Automation: the CHICA system.
Clinical guidelines are prevalent but frequently not used. Computer reminder systems can improve adherence to guidelines but have not been widely adopted. ⋯ The result is a system that both delivers "just in time" patient-relevant guidelines to physicians during the clinical encounter and accurately captures structured data from all who interact with the system. The system performs these tasks while remaining sensitive to the workflow constraints of a busy outpatient pediatric practice.

Facilitating cancer research using natural language processing of pathology reports.
Many ongoing clinical research projects, such as projects involving studies associated with cancer, involve manual capture of information in surgical pathology reports so that the information can be used to determine the eligibility of recruited patients for the study and to provide other information, such as cancer prognosis. Natural language processing (NLP) systems offer an alternative to automated coding, but pathology reports have certain features that are difficult for NLP systems. This paper describes how a preprocessor was integrated with an existing NLP system (MedLEE) in order to reduce modification to the NLP system and to improve performance. ⋯ An evaluation of the system was performed using manually coded data from the research project's database as a gold standard. The evaluation outcome showed that the extended NLP system had a sensitivity of 90.6% and a precision of 91.6%. Results indicated that this system performed satisfactorily for capturing information for the cancer research project.

Transforming written guidelines into electronic formats--international perspectives.
The Guidelines International Network (G-1-N www.g-i-n.net) is a major new international initiative involving guideline-developing organisations from around the world. G-I-N seeks to improve the quality of health care by promoting systematic development of clinical practice guidelines and their application into practice. The Network now has over 45 international members, most of whom prepare evidence-based clinical practice guidelines, or actively promote the use of evidence in practice. ⋯ To be effective, there must be formal internationally agreed standards that allow electronic guidelines to be shared and automatically updated. The Guidelines International Network will be taking a leading international role in working with designers and vendors of electronic decision support systems and tools to guarantee the integrity of guidelines when translated into electronic formats. This presentation by Catherine Marshall, Kitty Rosenbrand and Guenter Ollenschlaeger will: --explore current experiences from New Zealand, Germany and the Netherlands --identify issues from the perspective of guideline developers --make recommendations for establishing opportunities for software designers, vendors and informatics experts to collaborate with guideline developers to ensure that up to date evidence can be easily implemented and shared throughout the world.

Comparative StudyIntroduction of an operating room information management system improved overall operating room efficiency.
Operating Room (OR) information systems should manage the OR time, assigned to every surgeon, thereby minimizing the sum of costs of unused OR time and minimizing the costs of elective cases performed outside normal allocated OR time (excess OR-time). The aim of this paper is to illustrate how the introduction of an OR information system influenced daily OR activity performance. Since January 2001, we introduced an OR information system with a visual, airport-like, screen as central part, displaying all scheduled OR activity linked in real-time activity with all OR theatres. ⋯ In conclusion, in 2001 we recorded an increase in total OR activity for elective abdominal surgery by 7% in number of procedures and by 8% in total duration. However, in 2001 we recorded a decrease in excess time by 16% (123 h 04 min vs 147 h 20 min), which was for a large part due to a 23% decrease in unused OR time in 2001 compared to 2000 (35 h 21min vs 46 h 45 min). Therefore, the introduction of an OR information system, with a real-time visual display of ongoing OR activity, resulted in a increased performance of OR activity, with more OR procedures performed despite less excess time and less extra costs.

Telepresence and telemedicine in trauma and emergency care management.
The use of telemedicine is long-standing, but only recently has been applied to the specialties of trauma, emergency care, and surgery. Subsequently the concepts of teletrauma, telepresence, and telesurgery have evolved and are being integrated into modern care of trauma and surgical patients. This chapter will review the current applications and future endeavors of telemedicine and telepresence to trauma and emergency care as the new frontiers of telemedicine application.
