Information Systems and Health Care XIII: Examining the Critical Requirements, Design Approaches and Evaluation Methods for a Public Health Emergency Response System

Research pertaining to emergency response systems has accelerated over the past few years, particularly since 9/11 events, and more recently due to Hurricane Katrina and concern of the avian flu pandemic. This study examines the requirements that are the most demanding with respect to software and hardware, and the associated design strategies for a public health emergency response system (ERS) for electronic laboratory diagnostics consultation. In addition, this study illustrates ways to evaluate the design decisions. An important goal of a public health ERS is to improve the communication and notification of life-threatening diseases and harmful agents. The system under study is called Secure Telecommunications Application Terminal Package or STATPack. STATPack supports distributed laboratories to communicate information and make decisions regarding biosecurity situations. The intent of the system is to help hospital laboratories enhance their preparedness for a bioterrorism event or other public health emergency. The practical nature of this research concerns how an ERS diagnostic and consultation system was designed to alert and support first responders and Subject Matter Experts (SMEs). The academic nature of the research centers on the critical requirements of an ERS and how these unique needs can be met through careful design. Understanding the critical requirements will assist developers to better meet the expectations of the users. Specifically, I conducted a thirteen month study analyzing the requirements, design, and implementation of the system

Communication Media for Distributed Software Design

As virtual software projects are becoming more popular, it is also more common for software design, one of the key activities in software development process, to be conducted in the distributed context. Previous research has shown that communication media had an impact on the development of shared-understanding among team members in virtual teams. However, how communication media influences the development of shared-understanding among team members in software design, an activity where communication among team members are intense and complicated, is not well-understood. Therefore, within the scope of this study, we would like to conduct a case study to examine how virtual software development teams use communication media in their software design activities and how their usage influence their shared-understanding of the user requirements and design solutions. The outcome of the study is expected to validate the Media Synchronicity Theory in the distributed software design context as well as informing practitioners of the appropriate communication media usage for conducting distributed software design

Assessing the Reliability, Validity and Adaptability of PSSUQ

Psychometrically qualified usability evaluation instruments offer many advantages to the usability practitioner. Advantages include objectivity, replicability, quantification, economy, communication, and scientific generalization. It is important that instruments used in usability evaluation have shown acceptable estimates of reliability, validity, adaptability and practicality. This paper compares the psychometric properties of the Post-Study System Usability Questionnaire (PSSUQ) instrument in Lewis’ study to a recent study that tailored the PSSUQ instrument to measure the user satisfaction of the usability of a webbased health provider interface. Lewis reported that the PSSUQ had acceptable psychometric properties. However, Lewis’ stated PSSUQ had limited generalizability and needed further examination. This research validated the PSSUQ instrument using a larger sample size in a different domain. The factor analysis and the clustering of the sub-scale items were different than Lewis’ results. Nevertheless, this research concluded that the PSSUQ instrument is adaptable and produced solid psychometric results

Improving Antibiotic Resistant Infection Transmission Situational Awareness in Enclosed Facilities with a Novel Interface Design for Tactical Biosurveillance

The implementation of the Electronic Health Record to substantially improve the practice of medicine has not fully reached its projected potential partly due to many barriers to its adoption. There is growing evidence that one of the reasons for the delay in the adoption of EHR has been due to the negative impact of current EHRs on the clinician-patient interaction, clinician workflow and communications. This research studies the usability of the Electronic Health Record for clinicians involved in cardiac care by evaluating various clinician-patient interaction workflows. The aim of the study is to identify inefficiencies by examining the similarities and differences among various clinician-patient interaction workflows. This research is presented as “work in progress”

Requirement Prioritization Decision Factors for Agile Development Environments

In an agile development environment, project planners continuously prioritize work tasks so requirements that provide the most value are delivered first. This strategy is based on Value Based Software Engineering principles that different requirements deliver different levels of value and diverse stakeholders view the importance of the value of various requirements differently and thus, will prioritize them differently. However, we found that there are several core values that stakeholders have more agreement in terms of relevancy and importance than others. By knowing these core values, project planners have increased insights as to which requirements should be prioritized higher, hence, hopefully increasing overall stakeholder satisfaction and reducing project risk

Examining the Success of a Youth Care Management Information System through the Lenses of Novices

The goal of the research is to evaluate the success of novice end user interactions with a newly developed youth care management information system (YCMIS) that was designed to replace a paper based system managing mentally challenged clients. Delone and McLean’s (1992) framework of information system (IS) success was utilized in the evaluation which predicts the success of the end user interaction by measuring six independent variables; end user’s satisfaction, usage, system quality, information quality, individual impact, and organizational impact. In this study researchers used a semi-structured group interview to collect the data. The interview questions were designed to address the six independent variables measured in the Delone and McLean (1992) success model which are to determine the dependent variable, IS success. In conclusion, the YCMIS system was found to be a success and the interviews also identified unintended organizational value and efficiencies
