سیستم مدیریت پایگاه داده مغز کامپیوتری برای دپارتمان رادیولوژی در بیمارستان Computerized Brain Database Management System for Radiological Department in Hospital

I. INTRODUCTION Computed medical record database management is increasingly important as information and computer technology progress rapidly. Medical records contain treatment history and relevant experiences pertaining to the patients need to be documented accurately and efficiently. In many parts of the worlds, including Malaysia, clinical documentations are still being handwritten on forms and filed into paper medical records. The shortcomings of paper records are well identified, for example, illegibility and poorly organized records may lead to information gaps or inconsistencies, when used by another or even the same user later on. Hardcopies of documents are slow to be transferred around, with higher risk of being misplaced. In addition, when handled by multi-users in multi-locations, the quality of safekeeping can be significantly affected. [1, 2]. The advent of computer technology has introduced enormous possibilities for electronic documentation and usage of electronic medical records. The motivation of this system is to create a tailor-made computerized brain database management system for the Radiology Department of selected hospitals in Malaysia. This is achieved by studying the existing system and its problems, and then designed an appropriate database system. The work flow of the old filing system is first to create record, on which the diagnosis and treatment report are documented by various personnel. The report is then filed and stored in the department. This is repeated until the patient is discharged, where the record is then taken out and stored in the Medical Record Unit of the hospital. With respect to the scanning records, the medical images are also stored in the paper folder record. After the installation of the new system, the database will be used to deduce certain useful information about the brain infarction patients in the hospital. In Malaysia, stroke is the main cause of mortality and morbidity, after heart disease and cancer. Stroke is a multiple factorial disease regulated by modifiable and non-modifiable risk factors. Modifiable factors include a history of hypertension, diabetes mellitus, obesity, smoking and obstructive sleeping apnea syndrome. Nonmodifiable factors include age, sex and race. Stroke is known as a cerebrovascular accident (CVA), which is rapidly developing loss of brain function due to disturbance in the blood supply to the brain. Ischemia caused by blockage, or a hemorrhage is known as the common reason for stroke [3]. On brain imaging method, computed tomography (CT) and magnetic resonance imaging (MRI) are the most commonly imaging methods used in Malaysia. MRI has proven to have a better reliability and sensitivity than CT in brain imaging, and it is a proven research and diagnostic tool. However, CT scan is also widely available, being fast, easy, and less expensive than MRI [4 – 7].
