Moving mobile: using an open-sourced framework to enable a web-based health application on touch devices.
Computer devices using touch-enabled technology are becoming more prevalent today. The application of a touch screen high definition surgical monitor could allow not only high definition video from an endoscopic camera to be displayed, but also the display and interaction with relevant patient and health related data. ⋯ This paper describes an approach taken to overcome these problems. A real case study was used to demonstrate the novelty and efficiency of the proposed method.

Overrides of clinical decision support alerts in primary care clinics.
Clinical Decision Support (CDS) systems can alert physicians about potential clinical risks and suggest suitable treatment alternatives at appropriate times in the health care process. We evaluated the frequency with which physicians overrode medication alerts and the override reasons provided. ⋯ Physicians overrode more than half of CDS medication alerts, with formulary, age-based, and renal substitutions the most likely. Many drug-drug and drug-allergy interactions overridden had the potential to cause patient harm.

Video segmentation of moving humans for assistive environments.
In this paper, we present two recently proposed efficient methods for human segmentation from video in indoor environments: the illumination sensitive background method and the self-organizing background subtraction (SOBS) method. Both methods maintain multiple background models. ⋯ The video data are acquired indoors from a fixed fish-eye camera in the living environment. The paper presents the algorithmic implementation and modifications details, while results are also presented for a small number of video sequences.

Critically injured patients are often found in unusual positions and environments which can hinder the first responder's access to render necessary care. This work describes the use of the videolaryngoscope in airway management of the critically injured patient under unusual conditions.

Utilizing electronic health record data to determine the health of the medication process after the relocation of a children's hospital.
Hospital relocation is a highly complex undertaking, which has the potential to interrupt operations and poses risks for patients, staff, and providers. Little is known how hospital relocation impacts on workflow and communication. ⋯ Overall performance of the medication process has declined slightly. We identified regional (unit) differences with the pediatric intensive care unit, which had the most significant changes to its workflow, experiencing a more than doubling of the time from ordering to medication administration. Overall, there was no significant difference in time-sensitive medication administration times. Evaluating the medication ordering-dispensing-administration process through readily available EHR data demonstrated that the impact of a hospital' s relocation on workflow and communication can be successfully monitored.
