Interactive Visualization and Exploration of Patient Progression in a Hospital Setting.
As medical organizations increasingly adopt the use of electronic health records (EHRs), large volumes of clinical data are being captured on a daily basis. These data provide comprehensive information about patients and have the potential to improve a wide range of application domains in healthcare. Physicians and clinical researchers are interested in finding effective ways to understand this abundance of data. ⋯ Through the use of optimized data structures and progressive visualization techniques, we allow users to interactively explore how patients and their progression change over time. Compared to existing techniques, our work provides additional flexibility in analyzing patient data and has the potential to be used in a real-time hospital setting. Finally, we demonstrate the utility of our approach using a publicly available intensive care unit (ICU) database.

A Simulation Study on Handoffs and Cross-coverage: Results of an Error Analysis.
Handoffs and cross-coverage are necessary for maintaining the continuity of patient care, yet both are potential sources of error, and may threaten patient safety and care. Handoffs are the transfer of patient information and accountability from one provider to another. Cross-coverage is the management of patients, of whom physicians who have little or no prior knowledge of, during nightshifts. ⋯ We collected data from thirty physicians from an academic medical center as they signed out six patients after responding to nurse calls. An error analysis of the sign-out data revealed 42 errors overall, with 28 omissions and 14 "erroneous data" errors. We then propose ways to prevent these errors through modification of the electronic medical record and support tools, and through higher awareness of human factors.

A Cross-Sectional Study of Prominent US Mobile Health Applications: Evaluating the Current Landscape.
Mobile health (mHealth) could offer unprecedented opportunity to provide medical support closer to the users. We have selected some relevant criteria to describe 100 apps from Google Play store and Apple's App Store's top suggestions in medical category. These characteristics were compared based on the paid or free nature of the apps, the target users: consumers or healthcare professionals, and the platform: Android or iOS. ⋯ Our study shows that even in top rated mHealth apps, a high proportion lacks some basic criteria regarding the quality of the apps including the presence of a privacy policy, describing content sources, participation of the target users in the app development, etc. Paid apps did not ensure better quality compared to free apps. The current mHealth market is not mature enough to be used widely and recommended by healthcare professionals.

Checklist as a Memory Externalization Tool during a Critical Care Process.
We analyzed user interactions with a paper-based checklist in a regional trauma center to inform the design of digital cognitive aids for safety-critical medical teamwork. An initial review of paper checklists from actual trauma resuscitations revealed that trauma team leaders frequently wrote notes on the checklist. To understand this notetaking practice, we performed content analysis of 163 checklists collected over the period of four months. ⋯ An analysis of types and amount of notes written by leaders of different experience levels showed that more experienced leaders recorded more patient values and physical findings, while less experienced leaders recorded more notes about their activities and task completion status. These findings suggested that a checklist designed for a high-risk, fast-paced medical event has evolved into a dual function tool, serving both as a compliance and memory aid. Based on these findings, we derived requirements for designing digital cognitive aids to support safety-critical medical teamwork.

Impact of Robotic Surgery on Decision Making: Perspectives of Surgical Teams.
There has been rapid growth in the purchase of surgical robots in both North America and Europe in recent years. Whilst this technology promises many benefits for patients, the introduction of such a complex interactive system into healthcare practice often results in unintended consequences that are difficult to predict. ⋯ Drawing on the approach of realist evaluation, we conducted a multi-site interview study across nine hospitals, interviewing 44 operating room personnel with experience of robotic surgery to gather their perspectives on how robotic surgery impacts surgeon decision making. The findings reveal both potential benefits and challenges of robotic surgery for decision making.
