Emergency departments (EDs) typically use a triage system to classify patients into priority levels. However, most systems do not specify how exactly route across and within the assigned Therefore, decision makers in EDs often have their own discretion patients. Also, patient waiting is perceived accounted for ED operations clearly understood. In this paper, using patient-level visit data, we structurally estimate cost structure of as by who make routing decisions. We derive policy...
The Hospital Readmissions Reduction Program (HRRP), a part of the U.S. Patient Protection and Affordable Care Act, requires Centers for Medicare Medicaid Services to penalize hospitals with excess readmissions. We take an economic operational (patient flow) perspective analyze effectiveness this policy in encouraging reduce develop game-theoretic model that captures competition among inherent HRRP’s benchmarking mechanism. show can be counterproductive: it increases number nonincentivized...
Smart SPHERES is a prototype free-flying space robot based on the platform. can be remotely operated by astronauts inside spacecraft, or mission controllers ground. We developed to perform variety of intravehicular activities (IVA), such as operations International Space Station (ISS). These IVA tasks include environmental monitoring surveys (radiation, sound levels, etc.), inventory, and mobile camera work. In this paper, we first discuss motivation for robots. then describe development...
Recently, Meta rolled out Oculus Quest 2 all‐in‐one VR systems which have brought more virtual reality entertainment and experiences for users to discover. A 5.46″ 773 PPI (pixel per inch), 1920 RGB × 3664, fast‐switch LCD with low‐persistence backlight is used get visual fidelity of around 21 PPD degree) without any blur or ghost artifact. In this paper, we will present the overview display architecture, performances some design challenges addressed.
Since 2004, NASA has been working to return the Moon. In contrast Apollo missions, two key objectives of current exploration program is establish significant infrastructure and an outpost. Achieving these will enable long-duration stays long-distance To do this, robotic systems be needed perform tasks which cannot, or should not, performed by crew alone. this paper, we summarize our work develop utility robots for lunar surface operations, present results lessons learned from field testing,...
Recently Meta has successfully launched the Quest Pro VR headset. High resolution local dimming LCDs are paired with pancake lenses to bring an immersive visual experience. In this paper, we will present overview of Infinite Display architecture, key user experience metrics, and discuss design challenges.
NASA is planning to send humans and robots back the Moon before 2020. In order for extended missions be productive, high quality maps of lunar terrain resources are required. Although orbital images can provide much information, many features (local topography, resources, etc) will have characterized directly on surface. To address this need, we developing a system perform site survey sampling. The includes multiple operating in variety team configurations, coordinated via peer-to-peer...
We are studying how robotic follow-up can improve future planetary exploration. Robotic follow-up, which we define as augmenting human field work with subsequent robot activity, is a exploration technique designed to increase productivity and science return. To better understand the benefits, requirements, limitations risks associated this technique, conducting analog tests teams at Haughton Crater impact structure on Devon Island, Canada. In paper, discuss motivation for describe scientific...
Emergency departments (EDs) typically use a triage system to classify patients into priority levels. However, most systems do not specify how exactly route within the assigned levels, hence, decision makers in EDs often have their own discretion patients. Also, patient waiting is perceived and accounted for ED operations clearly understood. In this paper, we identify cost structure by patient-routing maker, based on visit data, derive policy implications make suggestions improving systems.

Problem definition: Emergency department (ED) delay announcement systems are implemented in many countries. We answer three important questions pertaining to the operations and effectiveness of such by studying public hospital network ED waiting time (WT) system Hong Kong’s “universal” healthcare system: (1) How patients aware (and sensitive to) WT announcements? (2) these announced WT? (3) can Kong government improve system? Methodology/results: study over 1.3 million patient visits 17 tier...

Abstract Background Pay‐for‐performance (P4P) programs have been implemented in various forms to reduce emergency department ( ED ) patient length of stay LOS ). This retrospective study investigated what extent the timing disposition Metro Vancouver s was influenced by a ‐based P4P program. Methods We analyzed visit records four major hospitals Vancouver, Canada. For each , we individually tested whether distributed discontinuously at target before and after program terminated. effective...
Several Emergency Medical Service (EMS) agencies across the US have demonstrated that time spent by EDs on ambulance diversion can be reduced implementing community-wide policies restrict duration and frequency of episodes. However, mechanisms through which these reductions materialize are not well understood. respond to such restrictions improving their patient flow processes reduce crowding and, thereby reducing need for frequent prolonged Alternatively, they raise crowding-threshold,...
Recent studies suggest that orthognathic surgery can improve facial age and personality profiling. The authors expand on these findings by assessing the role of patient profile sociodemographics perceived changes following surgery.Preoperative postoperative images 65 patients operated a single surgeon were randomly assorted rated 30 respondents. Patient profiles categorized as convex, concave, or straight. Paired unpaired t tests used to assess differences preoperatively postoperatively....
