    Information quality assessment framework: case of the national safety net program single registry system
    (Strathmore University, 2016) Mwangi, Evelyn Wambui
    The primary goal for IS applications is to deliver information which is accurate, timely, and relevant information to managers. Information quality is viewed as an essential element in measuring information system success. Assessing information quality and understanding areas of improvement is important to ensure that information systems are performing optimally. This research seeks to identify a means to assess information quality for the National Safety Net Program Single Registry System with the aim of improving the information it generated. This research proposed a three-phase framework that is iterative – information quality assessment, improvement, and proactive information quality management. This framework is anchored on the fact that continuous improvement is vital when ensuring in quality information. Nonetheless, assessment is the essentially the first phase to establish the status of information quality within an organization. For organizations that have already established this status, identifying the areas for improvement is the place to start this iterative process. Otherwise the c framework for proactive management of information quality is a fundamental and a strategic guide for all organizations to consider. This research took an exploratory approach to understanding the factors that influence information quality. A sample size of 46 was identified from the target population of 84 users of the single registry. A survey was undertaken coupled with key informant interview and desk review to ensure collect data for this research. The results showed that the information on the single registry was of good reputation and users perceived it to be objective. It is evident that there is need to assess these information quality dimensions from time to time to ensure that the quality is maintained and the goal of the information system is achieved.

    Near-Field Communication based-model for health information portability
    (Strathmore University, 2016) Onyancha, Paul Morumbwa
    Health Information Portability is an important concept in the healthcare sector because of the patient’s ability to carry their medical data when visiting a health care center. Data that can be stored in hitherto time-honored systems such as Health Information Systems and Electronic Medical Record (EMR) systems is diverse and hence a need for a focused approach on the data to be stored and retrieved securely when needed. Empirical evidence shows a lack of clear technological solution for Health Information Portability in the era of efficiency of mobile devices accessing stored EMRs. Near Field Communication (NFC) technology presents a new dimension for enterprises such that with NFC tags, any object can be turned into a digital data point that can transfer information to NFC-enabled mobile devices using short range radio waves. In this research, agile development methodology was used and different systems, models and prototypes incorporating NFC tags, NFC readers, mobile application, encryption and decryption studied and their beneficial aspects borrowed to create a novel application that runs on the doctor’s NFC-enabled phone that can read and write into a patient’s NFC-enabled medical card. Security features such as password, decryption and encryption of data on the NFC card and the vital EMR data necessary as per doctor’s recommendations, which included patient’s name, allergies and blood group, were incorporated. A model developed showing communication from a host PC and a mobile phone client demonstrated the machine-to-machine communication NFC concept. Authentication, data capture and deploy, data view and edit, mobile to host PC connection were tested and all showed a pass. This system will help reduce incidences of duplication of medical tests leading to reduction in medical costs for patients, assist doctors in making quick clinical decisions and also form the basis for future research on NFC in healthcare.
