Comparative StudyDirect versus indirect laryngoscopic visualization in human endotracheal intubation: a tool for virtual anesthesia practice and teleanesthesiology.
When performing the ABC's of care for the trauma patient, airway management is of paramount importance. Management of the airway is often difficult because medical personnel caring for the patient do not commonly intubate patients or manage airways. To accomplish endotracheal intubation, a direct line of sight must be accomplished through the mouth, pharynx and larynx to the glottic opening. ⋯ Indirect "virtual" laryngoscopy is an advanced technology method which will advance the development of teleanesthesiology practice. Videolaryngoscopy is an enabling technology for development of remote telementoring of trainee intubation skills curricula using video enabled distributed learning systems. This research was conducted following an approved University of Nebraska Medical Center institutional review board protocol.

From guidelines to careflows: modelling and supporting complex clinical processes.
Research on computer interpretable clinical guidelines has largely focused on individual points of care rather than processes of care. Whether we consider simple aids like clinical alerts and reminders or more sophisticated data interpretation and decision-making, guideline developers tend to focus on specific tasks rather than processes like care plans and pathways which are extended in time. ⋯ We also briefly discuss the distinct theoretical frameworks which have grown up around them, notably Petri nets for workflow modelling and mathematical logics for guidelines. We conclude that these offer complementary views of clinical processes and that a key research challenge is find a way of unifying them.

The contextual nature of usability and its relevance to medical informatics.
We report from three usability evaluations of health information systems that illustrate the value of seeing usability as a context dependent property of a product. We show how the definition of usability in ISO 9241-11 can be used as a guiding principle in the evaluation, specification and design of such systems. The contextual view on usability is particularly important for health information systems because of their great diversity concerning user groups, tasks, and work environments.

It is well known that in most countries, there is a perennial shortage of specialists in neurosciences. Even the few available neurologists and neurosurgeons are clustered in the metros and urban areas. ⋯ At the same time there has been an unprecedented growth in ICT (Information and Communication Technology). In this article, the authors review the increasing use of telemedicine in neurosciences.

Implementing a telehealth program from the technical standpoint can be an engineering and financial challenge due to associated costs such as hardware, software, networking, administration and human expertise. To maximize potential and minimize costs, it makes sense to leverage existing telecommunications infrastructures and tailor the program based on what is available. This is especially critical in developing nations where funding is often limited.
