Objective: High Risk Reminder (HRR) system is the lately mobile application technology developed by Taipei Medical University of Medical Informatics Research Institute. The objective of HRR is to provide high risk patient test results such as lab, radiology, pathology to physician immediately by mobile short message and internet e-mail. The mobile short message is to provide abstract information to physician such as patient name, inpatient bed ward number, the abcdrmal test result. The physician can receive the latest patient’s abcdrmal test information at any place, time. Therefore, the physician can take intervention treatment as soon as possible for patient treatment. Moreover, the physician wants to know more detail the high risk patient’s information can open the e-mail to review the patient’s profile in order to provide treatment plan. The purpose of using the mobile and internet technology is to improve patient safety. The WF Teaching Hospital has using the HRR system to serve its patient and physician for 6 months. There are more than 600 mobile short messages and e-mail communication for physicians. To reach the patient safety goals is the critical mission of WF Hospital. Therefore, the evaluation of HRR patient safety contribution needs to analyze.。This study is introducing HRR system functions and evaluating HRR’s contribution.。This research is based on the empirical study. We investigate the HRR’s impaction to assist high risk patient severe test result information communication for physician to assist patient’s treatment for physician and hospital. Meanwhile, the two mobile short message and e-mail communication media which one is more effective for physician is analyzed also. Design: This study measures dimensions of information quality, system quality, use, user satisfaction, individual impact and organizational impact based on the D&M IS Success Model. Multivariate techniques were used to evaluate the relationships of the Model. Measurements: The dimensionality of each scale and degree of association of each item with the attribute of interest were determined by principal components factor analysis with orthogonal varimax rotation. The reliability of each resultant scale was computed using Cronbach’s alpha coefficient. Construct validity was examined through factor analysis and by correlation analyses. Multiple regression techniques were used to evaluate the relationship between the set of six dimensions and comparison of PHS and e-mail. Results: Physicians have using the HRR systems are the surveyors composed of this survey samples. There are 56 questionnaires had been distributed the physicians. Seven questionnaires are invalid due to rarely using the HRR system. The valid questionnaires are 85%。Of the respondents, 93% were male; 73% were undergraduate; 90% were primary physicians.。 From the research finding , the two communication medias of short message, and e-mail are positive relationships for effective and efficiency communication for physicians to assist high risk patient severe test result information delivery. The research two constructs of PHS and e-mails’ indicators are positive for improving better communication; The information quality for user’s effectiveness, satisfaction relationship impacts for users and organization. Comparison effective communication between PHS and e-mail media, the research finding is PHS is more powerful than e-mail to deliver information for physician. From regression analysis, each □ value of PHS is higher than e-mail. The individual using PHS and e-mail is positive to effect the hospital to diffuse of HRR system. Conclusion: The survey of user’s satisfaction of using the HRR system is reached over 70%. However, 60 % of physicians indicates the HRRS provides efficiency and effectiveness each high risk patient’s information causing the information overload. This is the drawback of the implementation HRR system. How to decrease the information overload pressure needs to solve in the near future to improve HRR system. Furthermore, utilization mobile technology to provide two channel communication for physician to access the patient‘s database treatment, test, medication information to integrate all required information to develop the well treatment plan to improve patient safety and reduce patient risk.

The business benefits of IT projects are becoming the main determining factor in selecting projects at the ex-ante justification stage. The core stakeholders, i.e. the business management and IT professionals are charged with the task of evaluating the benefits of IT investment. Despite high adoption rates of formal IT investment appraisal methods, there is still on-going evidence that show organisations not being able to appropriately evaluate IT benefits. This study investigates the process of IT project evaluation at the ex-ante justification stage to understand factors that contribute to ineffective practical application of evaluation and based on the findings, to explore how these factors can be redeemed to improve the benefit evaluation process. A case study research was conducted to explore how benefits can be evaluated appropriately within its context in a tertiary educational institution. The case study research approach enabled the researcher to gain a complete and in-depth understanding of the process and activities involved to identify and measure benefits at the justification stage. Business middle managers that are involved and responsible for IT project justification were approached from various business units as case study participants. Interview questions addressed various aspects of the benefits evaluation process in reference to participants’ experience and past IT project justifications. Content analysis was used to identify frequencies and intensities with which themes and concepts appear in interviewee responses. In addition, a cause and effect relationship tool was used to summarize the research findings for better data analysis and interpretation. The findings indicate factors that contributed to ineffective benefit evaluation in the organization. Close collaboration and partnership between business management and IT professionals is shown to be a crucial component of the justification process. The suggested role of IT management exceeds beyond the task of technical advisor and involves the task of being a coach, informer, educator, assessor, transparency and communication agent. The results also show how best the measurement process can be performed at this stage. This study confirms that business management’s clear understanding of IT benefit concepts is necessary in the evaluation process. Based on the findings, an IT benefit evaluation method is developed as a modification of the current justification process in the organisation. The results presented in this study lay plausible insights for additional approaches to IT benefit evaluation research. It compels researchers to consider new methodologies in the quest for improving benefit evaluation. / Dissertation (MIT)--University of Pretoria, 2011. / Informatics / unrestricted

Motivated by IT evaluation problems identified in a large public sector organization, we propose how evaluation requirements can be supported by a framework combining different models and methods from IS evaluation theory. The article extends the content, context, process (CCP) perspectives of organizational change with operations research techniques and demonstrates the approach in practice for an Enterprise Resource Planning evaluation.

Evaluation is a vital--yet challenging--part of IS/IT management and governance. The benefits (or lack therefore) associated with IS/IT investments have been widely debated within academic and industrial communities alike. Investments in information technology may or may not result in desirable outcomes. Yet, organizations must rely on information systems to remain competitive. Effective evaluation serves as one pathway to ensuring success. However, despite a growing multitude of measures and methods, practitioners continue to struggle with this intractable problem. Responding to the limited success of existing methods, scholars have argued that academicians should first develop a better understanding of the process of IS/IT evaluation. In addition, scholars have also posited that IS/IT evaluation practice should be tailored to fit a given organization's particular context. Of course, one cannot simply tell practitioners to "be contextual" when conducting evaluations and then hope for improved outcomes. Instead, having developed an improved understanding of the IS/IT evaluation process, researchers should articulate unambiguous guidelines to practitioners. The researcher addressed this need using a multi-phase research methodology. To start, the researcher conducted a literature review to identify and describe the relevant contextual elements operating in the IS/IT evaluation process: the purpose of conducting the evaluation (why); the subject of the evaluation (what); the specific aspects to be evaluated (which); the particular evaluation methods and techniques used (how); the timing of the evaluation (when); the individuals involved in, or affected by, the evaluation (who); and the environmental conditions under which the organization operates (where). Based upon these findings, the researcher followed a modeling-as-theorizing approach to develop a conceptual model of IS/IT evaluation. Next, the conceptual model was validated by applying it to multiple case studies selected from the extant literature. Once validated, the researcher utilized the model to develop a series of methodological guidelines to aid organizations in conducting evaluations. The researcher summarized these guidelines in the form of a checklist for professional practitioners. The researcher believes this holistic, conceptual model of IS/IT evaluation serves as an important step in advancing theory. In addition, the researcher's guidelines for conducting IS/IT evaluation based on organizational goals and conditions represents a significant contribution to industrial practice. Thus, the implications of this study come full circle: an improved understanding of evaluation should result in improved evaluation practices.
