Performance evaluation of artificial intelligence classifiers for the medical domain.
The application of artificial intelligence systems is still not widespread in the medical field, however there is an increasing necessity for these to handle the surfeit of information available. One drawback to their implementation is the lack of criteria or guidelines for the evaluation of these systems. ⋯ This paper shows evidence that the most prevalent form of intelligent system, neural networks, is generally not being evaluated rigorously regarding classification precision. A taxonomy of the types of evaluation tests that can be carried out, to gauge inherent performance of the outputs of intelligent systems has been assembled, and the results of this presented in a clear and concise form, which should be applicable to all intelligent classifiers for medicine.

Randomized Controlled Trial Comparative Study Clinical TrialThe role of rigid vs. dynamic instrumentation for stabilization of the degenerative lumbosacral spine.
This is a prospective comparative randomised study to compare the immediately postoperative effects of a rigid versus dynamic instrumentation for degenerative spine disease and stenosis on the standing sagittal lumbar spine alignment and to investigate if a dynamic spine system can replace the commonly used rigid systems in order to avoid the above mentioned disadvantages of rigid fixation. ⋯ Both rigid and dynamic instrumentations restored lumbar lordosis, sacral tilt, distal lordosis and increased the foraminal diameter at the level L4-L5 resulting in an indirect decompression of the nerve roots at this level . Both rigid and dynamic instrumentations applied in the lumbosacral spine to treat degenerative disease secured L3 to S1 sagittal spine profile close to preoperative levels, that should theoretically guarantee a pain-free postoperative course. This study supports the belief that the dynamic system can be used with the same indications with the rigid in degenerative lumbar spine because it can offer equally good short-term results regarding sagittal spine alignment while simultaneously it has the previously mentioned advantages (avoidance stress shielding etc).

This chapter focused on some of the key issues of Health and Nursing Informatics Education. First an historical overview of Health and Nursing Informatics Education is presented. ⋯ Because of the variety of educational systems, the International Medical Informatics Association (IMIA) felt the need to develop international recommendations in health and medical informatics education. From a nursing informatics perspective, the IMIA recommendations in Nursing Informatics Education are discussed.

Self-administered decision support tool for triage: results of a retrospective study.
This study was designed to evaluate the safety of a self-administered triage tool. ⋯ The system disposed 51.1% of cases appropriately and under-disposed 4.4% of cases. Comparison between the system and the emergency physician shows that all cases under-disposed by the system are also under-disposed by the physician.
