This section presents foreign related literatures relevant to the proposed system.
Computers are being employed in clinical medicine in hospitals for various purposes. They can act as arithmetic calculators, they can process and analysed output from the recording devices, and they can make possible the automation of various machine systems.
However, in the field of case records their role is much less well defined, for here the organization of data as preliminary to computer input is the real stumbling-block. Data banks of retrospective selected clinical information have been in operation in some canters for the number of years. Attempts are now being made to design computerized "total information systems" to replace conventional paper records, and the possibility of automated diagnosis.
Golla (2007) stated that record keeping is an organized way of storing valuable information about certain persons handling of such records the proposed system includes all the important records that are organize and place on the system database that are subjectively relating to the transaction of the hospital.
According to Nanda (2006), the present situation of healthcare in developing countries like India are quite discouraging, as the physicians use a paper based system whereby they record patient information, diagnosis and treatments on a “Case Sheet”. Abdul (2008) mentions that each time a patient visits a hospital, a new case sheet is created, and this creates an excess of paperwork, repetition of examination done previously leading to over-consumption of work force and other resources. In India, the case sheet is an official and legal document written by healthcare staff about all the medical information of a patient. It includes past medical history, present complaints, results of examinations done, diagnosis and treatment and the condition of these medical records in public hospitals in quite disappointing. This situation is due to reluctant hospital administration or inefficient medical record staff and it is increasing constantly by the year. Abdul (2008) indicates that one of the important issues in paper-based records are, all the clinical information is written in free style, and chances are high to miss or forget some important information, as this will lead to serious effect on patient’s treatment and care. The case sheet is a hard copy that can be accessed by one person at a time and needs physical transfer for other physicians to access. Retrieving a record will be a hard task given number of medical records present and missing a record won’t be a surprise in a huge pile of paper based medical records. Moreover, with time, information in paper records gets diminished of ageing paper and ink, even fire accidents or natural disasters can ruin the archive of paper records. Karim (2008) explains that all the above discussed issues can be over-come by implementing EMR/EPR systems, it can not only solve the problems but also improves the efficiency of healthcare by increasing accessibility, and needs less resources to maintain records. EPR system can be used as a resource of researchers, it will be a tool for disease surveillance, which can be used for public health initiatives and for practicing Evidence based medicine. "It is nearly impossible to overemphasize the importance of keeping inventory levels under control," Ronald Pachura wrote in an article for IIE Solutions. "Whether the problems incurred are caused by carrying too little or too much inventory, manufacturers need to become aware that inventory control is not just a materials management or warehouse department issue. The purchasing, receiving, engineering, manufacturing, and accounting departments all contribute to the accuracy of the inventory methods and records." It is little wonder that business experts commonly cite inventory management as a vital element that can spell the difference between...
