I would also like to thank all the respondents who took their valuable time to participate in this study. I sincerely thank my supervisors, Dr. N.H. Shidende and Dr. H.J. Mongi for supervising me in this study. I have greatly benefited from their patience, guidance, encouragement, and constructive criticisms. I feel to have been privileged to work under their supervision. Appreciation should also go to all academic staff members of the College of Informatics and Virtual Education (CIVE), at the University of Dodoma for their advice, counseling and support during the entire period of the study. My special thanks also go to my classmates. Their cordial friendship, which they shared with me, made me enjoy academically. I feel also obliged to give special thanks to the Haydom Lutheran Hospital (H.L.H) administration, under the Managing Medical Director Dr. E. Nuwass for giving me an opportunity to go for further study. I take this opportunity to say that, I will utilize the knowledge I got for the ICT department at H.L.H and Tanzania in general. Lastly, I thank my family for what they did to me. Most importantly, I thank my parents’ madam Marietha, my father Mr. Arusha, my lovely wife Elizabeth and our lovely children Ernest, Erick and Emanuel who encouraged me to work hard in my life. It is impossible to mention all people who helped me in one way or another, but it suffices to say here that were it not for them I would not have reached this level. However, it should be noted that, any shortcomings on this research are entirely belong to me. iii DEDICATION This research work is dedicated to Ernest, Erick, Emanuel and Elizabeth. iv ABSTRACT This study, has intended to design a model for an Integrated Hospital Information System in Tanzania, and was conducted at four hospitals from Dodoma and Manyara regions respectively. A sample of 90 respondents participated in the study from a purposive and non purposive sampling. A Statistical Package for Social Science (SPSS) was used to analyze the quantitative data. Findings have revealed that, Integrated Hospital Information System (iHIS) in Tanzania requires infrastructure, system development, data sharing and interoperability and unique identification as well as information security and privacy. Strong security measures must be observed before integration, during integration and after integration of HIS system. The study not only should design an architectural model for iHIS but also the design has considered the fact that, most patients’ records which were captured by the HIS deployed in various hospitals in Tanzania did not have either common unique identities or biometric data, which could be used to identify a patient’s record throughout the country. An integrated hospital information system which could enable sharing of patients’ information between the hospitals is an important tool for healthcare providers to provide continuous treatment to patients, understand the background of the disease, understand how the patient was diagnosed and knows the treatment the patient is on. This study also, recommends the following to be the principle for achieving the iHIS. The systems should be as flexibility as possible in order to allow further growth and its expansion; interface engine must be constituted with technologies that suit for integration such as XML, JSON and REST as well as patient having a unique identification number which can be used in all integrated systems. v TABLE OF CONTENTS CERTIFICATION......................................................................................................... i DECLARATION AND COPYRIGHT ........................................................................ ii ACKNOWLEDGEMENT ......................................................................................... iii DEDICATION ............................................................................................................ iv ABSTRACT ................................................................................................................. v TABLE OF CONTENTS ............................................................................................ vi LIST OF TABLES ....................................................................................................... x LIST OF FIGURES..................................................................................................... xi LIST OF APPENDICES ............................................................................................ xii LIST OF ABREVIATIONS ..................................................................................... xiii CHAPTER ONE: INTRODUCTION ...................................................................... 1 1.0 Background of the study ........................................................................................ 1 1.1 Statement of the Problem ....................................................................................... 3 1.2 Research Objective ................................................................................................. 4 1.2.1 Main Objective .................................................................................................... 4 1.2.2 Specific Objective ............................................................................................... 5 1.3 Research Questions ................................................................................................ 5 1.4 Significance of the Study ....................................................................................... 5 1.5 Scope of the study. ................................................................................................. 6 1.6 Organization of the Dissertation. ........................................................................... 6 CHAPTER TWO: LITERATURE REVIEW ......................................................... 7 2.0 Introduction ............................................................................................................ 7 2.1 Hospital information system .................................................................................. 7 2.1.1 Healthcare Systems Interfacing Overview .......................................................... 8 2.1.1.1 Point-to-Point Approach .................................................................................. 9 2.1.1.2 Interface Engine Approach. ............................................................................. 9 2.2 Architectures of computing systems in hospitals ................................................. 10 2.2.1 The central system ............................................................................................. 10 2.2.2 Modular system ................................................................................................. 11 2.2.3 Distributed systems ........................................................................................... 11 vi 2.2.4 Related Work: ................................................................................................... 12 2.2.4.1 General architecture for the VEPR ................................................................ 13 2.2.4.2 Security issues ...............................................................................................
