Initial implementation of mixed reality simulation targeting teamwork and patient safety.
Patient safety is one of the most pressing challenges of modern healthcare. Being a multifactorial problem, patient safety requires improvement interventions on multiple levels including individual, team and organization as a whole. ⋯ Each simulation session was followed by facilitated debriefing and teaching new team communication skills. Team performances were assessed by both direct observation and team's self-assessment where each team member assessed his or her own performance as well as the performance of all other team members (360 degree assessment).

The posterior skeletal thorax: rib-vertebral angle and axial vertebral rotation asymmetries in adolescent idiopathic scoliosis.
The deformity of the ribcage in thoracic adolescent idiopathic scoliosis (AIS) is viewed by most as being secondary to the spinal deformity, though a few consider it primary or involved in curve aggravation. Those who consider it primary ascribe pathogenetic significance to rib-vertebra angle asymmetry. In thoracic AIS, supra-apical rib-vertebra angle differences (RVADs) are reported to be associated with the severity of the Cobb angle. ⋯ RVADs are largest at two and three vertebral levels above the apex where they correlate significantly and positively with Cobb angle and AVT but not AVR. In right thoracic AIS, the cause(s) of the RVA asymmetries is unknown: it may result from trunk muscle imbalance, or from ribs adjusting passively within the constraint of the fourth column of the spine to increasing spinal curvature from whatever cause. Several possible mechanisms may drive axial vertebral rotation including, biplanar spinal asymmetry, relative anterior spinal overgrowth, dorsal shear forces in the presence of normal vertebral axial rotation, asymmetry of rib linear growth, trunk muscle imbalance causing rib-vertebra angle asymmetry weakening the spinal rotation-defending system of bipedal gait, and CNS mechanisms.

Repeated palpatory training of medical students on the Virtual Haptic Back.
The effectiveness of simulation-based training has been accepted with great success in many fields including medicine. Most of the simulation research and development in medicine has focused on surgery. ⋯ The Virtual Haptic Back (VHB) is a simulator based on virtual reality and haptics that is currently being used to train medical students in palpatory diagnosis. This study examined the effect of repeating the training on the VHB.

Using a low-cost simulation approach for assessing the impact of a medication administration system on workflow.
This paper describes the analysis of the impact of a medication administration system on clinical workflow. The methodological framework employed was based on in-depth analysis of simulated user interactions with a medication administration system. ⋯ Methodological considerations and issues in conducting such studies are discussed. The study indicated that use of the system would have a significant impact on nurse and physician workflow and that this impact could be accurately identified using simulation approaches prior to widespread release of such systems in real clinical environments.

Network design for telemedicine--e-health using satellite technology.
Over the last decade various international Information and Communications Technology networks have been created for a global access to high-level medical care. OP 2000 has designed and validated the high-end interactive video communication system WinVicos especially for telemedical applications, training of the physician in a distributed environment, teleconsultation and second opinion. WinVicos is operated on a workstation (WoTeSa) using standard hardware components and offers a superior image quality at a moderate transmission bandwidth of up to 2 Mbps. ⋯ The development of virtual hospitals and digital medicine helps to bridge the digital divide between different regions of the world and enables equal access to high-level medical care. Pre-operative planning, intra-operative navigation and minimally-invasive surgery require a digital and virtual environment supporting the perception of the physician. As data and computing resources in a virtual hospital are distributed over many sites the concept of the Grid should be integrated with other communication networks and platforms.
