A virtual reality cognitive screening tool based on the six cognitive domains.

Introduction: Early detection of cognitive impairment enables interventions to slow cognitive decline. Existing neuropsychological paper-and-pencil tests may not adequately assess cognition in real-life environments. A fully-immersive and automated virtual reality (VR) system-Cognitive Assessment using VIrtual REality (CAVIRE)-was developed to assess all six cognitive domains.

Toward real-world deployment of machine learning for health care: External validation, continual monitoring, and randomized clinical trials.

In this commentary, we elucidate three indispensable evaluation steps toward the real-world deployment of machine learning within the healthcare sector and demonstrate referable examples for diagnostic, therapeutic, and prognostic tasks. We encourage researchers to move beyond retrospective and within-sample validation, and step into the practical implementation at the bedside rather than leaving developed machine learning models in the dust of archived literature.

Retrospective matched cohort study of incidence rates and excess length of hospital stay owing to pressure injuries in an Asian setting.

Background: Little is known about stage 1 and 2 pressure injuries that are health care-acquired. We report incidence rates of health care-acquired stage 1 and stage 2 pressure injuries, and, estimate the excess length of stay using four competing analytic methods. We discuss the merits of the different approaches.
