Crash carts are mobile containers of medications and supplies used to resuscitate patients in emergencies within health care facilities. Contents and organization of carts often differ across hospitals and even departments within the same hospital. To support our team members in emergencies across our multi-hospital system, we created a system safety initiative to standardize and optimally organize adult crash carts. Our team established a three-phase user-centered research and design approach. First, we facilitated a collaborative design workshop with front line stakeholders to develop an initial cart organization. Second, 59 clinicians across 8 departments interacted with a cart mock-up and provided feedback. Finally, 18 clinicians participated in usability testing of the updated cart in 3 separate full simulations of realistic patient emergencies including an airway emergency (anaphylaxis), cardiac arrest (ventricular fibrillation), and sepsis using manikins. Observations and feedback from all three research phases contributed to a final medical supply list and crash cart design for our hospital system. This work also provides guidance for using co-design methods and usability testing within hospital environments.

Successful collaborative design requires in-depth communication between experts from different disciplines. Many design decisions are made based on a shared mental model and understanding of key features and functions before the first prototype is built. Large-Scale Immersive Computing Environments (LSICEs) provide the opportunity for teams of experts to view and interact with 3D CAD models using natural human motions to explore potential design configurations. This paper presents the results of a class exercise where student design teams used an LSICE to examine their design ideas and make decisions during the design process. The goal of this research is to gain an understanding of (1) whether the decisions made by the students are improved by full-scale visualizations of their designs in LSICEs, (2) how the use of LSICEs affect the communication of students with collaborators and clients, and (3) how the interaction methods provided in LSICEs affect the design process. The results of this research indicate that the use of LSICEs improves communication among design team members.

Design Conflicts

Due to the product complexity and time constraint, it is common to conduct a collaborative design process to consider design requirements concurrently from the product lifecycle. However, such multi-disciplinary integration process may lead to potential design conflicts which has to be further resolved as the development continues. In this research, we propose a novel analytic model by combining the concepts of Ideal Final Result (IFR) and Trends analysis in TRIZ theory to systematically find the possible design contradictions from a top-down approach. The IFR is used to represent the integration of the developing product requirements which are requested from the collaborative team members. We then apply Trends analysis to compare the current state of existing product and the IFR state of the developing product. Therefore after comparison we will transform the differences into 39 engineering parameters defined in TRIZ to acquire possible design contradictions among components. The contributions of this methodology not only derive design conflicts systematically, but also help designers jump out of their psychological inertia and perform the design process with IFR to achieve distinct innovation.

Past Experiences

AbstractArchitecture, engineering, and construction team members, while collaborating on building projects, rely on past experiences and content through the use of project design archives (whether in paper or digital format). Underutilization of potential knowledge in the decision-making process of data, information, and knowledge reuse is limited by access to these archives, because of sheer size, decontextualized content, and inconvenient access and presentation. This paper presents an integrated solution called CoMem–iRoom that leverages two technologies Corporate Memory (CoMem) and interactive Room (iRoom) developed at Stanford. CoMem–iRoom addresses critical limitations (content, context, visualization, and interactivity) constraining the process of collaborative exploration toward knowledge reuse and decision making.

The Impact

The current approach to validating the safety and effectiveness of most medical devices involves conducting usability testing with a single participant.However, this approach might not be appropriate for medical devices used by a team of individuals because it does not enable researchers to evaluate the impact of teamwork (e.g., collaboration, coordination, cross-checking) on the team’s use of the device. In this manuscript, we present four alternative approaches to conducting usability testing of medical devices used by teams, some involving a team of participants and some involving confederates who represent absent team members. We present important considerations for each approach and tradeoffs among approaches. Finally, we conclude by recommending an approach that best balances these tradeoffs.

Fusariums pecies are opportunistic fungi that play an important role in nosocomial infection. The reservoir of Fusarium species in the hospital is not well understood in our environment. Therefore, the present study sought to identify the reservoir of Fusarium species in hospital environment. Three hundred and sixty (360) samples were collected from the environment of two tertiary health care facilities A and B. The sample consists of water (120), soil (120) and plants (120) which were sourced from hospital environments. Cultures of these samples were performed and polymerase chain reaction was used to confirm Fusarium species. The most predominant specie was Fusarium oxysporum Hospital A:(57.3%) and Hospital B:(64.4%). Most of the Fusarium isolates (76.7%) were recovered from soil samples, followed by water (45.0%) and the least were from plants (30.8%). In conclusion the present study has demonstrated that hospital environment is a reservoir for Fusarium species. However, identification of such reservoir would further enhance effective infection control measures.

The mantra of industry today is to design products and processes using collaborative design teams. While the potential benefits of such a design philosophy are numerous and significant, many organizations find themselves falling short in the implementation. Sometimes these shortcomings are due to cultural and technical difficulties in the organization, but too frequently they are due to a lack of knowledge as to how to collaborate effectively. Described herein is an educational initiative by Syracuse and Cornell Universities to together teach collaborative design methodologies through a common two-semester, senior-level engineering design course. In the course, not only are the lectures taught to the two cohorts of students using at-a-distance technologies, but the students are teamed in cross-university teams to execute a series of 6-week design challenges, from preliminary through detailed thermal-structural design of the external skins of seconds-generation reusable launch vehicles. An Advanced Interactive Discovery Environment (AIDE), which is a computer-based infrastructure specifically designed for this course, is used to support both synchronous and asynchronous communications amongst the team members and with the faculty. Extensive surveys of the students, together with faculty observations, indicate that proper use of collaboration tools can facilitate effective geographically-dispersed design teams, making them as successful as local design teams.

Abstract The design framework research community utilizes the internet as a facilitator for collaborative activities. The internet provides a platform independent interface and geographic distribution. Information can be easily represented to the end-user using the HyperText Markup Language and can be coded in a reasonable timeframe. A shortcoming of exploiting this technology further is the reliance on existing Web servers to interface with analysis tools and design services. In this case, interactive components require auxiliary processes (called CGI scripts) to be started by the server that are used in an inefficient manner. This model does not provide the user-oriented capability required by standalone applications. Java offers improvements in client-side processing but a server bottleneck still exists. A novel approach using lean-servers is introduced as an alternative method for providing an efficient server-side computing model. In this case, internet requests are brokered directly by the design application by providing a gateway to the application’s programming interface using a HyperText Transfer Protocol compliant layer. This allows requests to be managed directly by the application rather than requiring auxiliary services. Step-by-step directions for implementing this approach using a case study of an existing design framework are given in this paper. A prototype system, called the Systems Programming Architecture for Collaborative Engineering, is described as one scenario for implementing the lean-server technology. Usability of the approach is demonstrated through a Design of Experiments example that is representative of modern design methods. This example also demonstrates collaboration because it executes asynchronously with multi-user intervention at any time during the process. In hindsight, the lean-server approach is an enabling technology for collaborative design and focuses future research direction on the establishment of collaborative design practices.
