Hospital Patient Management System - Development And Application Essay.

Question:

Discuss About The Development And Application Of New System?

The purpose of this project is to focuses on the Patient Management System software for controlling and monitoring all the activities in a hospital. This project is being developed in java that focuses on the general operations and activities of the hospital, which includes new patients, adding new member, addition of information, and finding the beds from the records, respective members and facility or officers to check if there is empty beds.

The proposed “Hospital Management System” is designed in order to help user’s maintenance and organize the hospital activities. This system is designed in a manner that beginner and the advanced users both can easily operate it. The features implemented in this system are a similar and well thought-out, combined with strong reporting capabilities and searching Insertion option. This proposed report generation for providing facility of hospital system can be helpful in getting good idea of which beds have been borrowed by which members and allows users a possibility to generate hard copy of the reports.

The proposed Hospital Management System has following four main modules: Extracting from Database module, Insertion to Database Module, Search Facility system, and Report Generation module.

The key questions for this analysis are: what are the existing problems? What could be done to solve the existing problem? System Analysis made here depends on the depth study of the different activities performed in the system including their impact outside and within the system.

In order to make system successful emphasis has been given on the problems, rigorously investigated and properly carried out about the system. This system has been analyzed in depth taken in account the relative needs of the system. Following are the categories of system analysis: initial investigation, Information Gathering, System planning, Feasibility studies, Applying analysis tools, and Cost/ Benefit analysis.

In the existing system, major disadvantages encountered are that for preparation of the list of borrowed beds and the beds that are available in the hospital consumes more time and takes one day process to verify the records. Transactions are being operated manually, so borrowing a bed and managing the patients becomes time consuming process. A computerized for this management will be more feasible, so it is recommended.

This hospital management system is based on an automated computerized system for the hospitals those are still being operated in traditional way. Through this system different users can search bed, add bed, search medicines, add medicines, edit information, update information, return left medicines, and checkout in less time. Following are the advantages of proposed system: More Storage Capacity, Lesser Errors, Search facility, Fast access to database, Quick transaction, Look Environment. This can be helpful in mitigating the issues related to the existing system.

System Analysis

Feasibility can be defined as the study of impact that can be happened in the organization through the development and application of a new system. It could be negative or positive and when the positives nominate negatives, the system can be considered as feasible. Following are the ways to perform feasibility of the system.

It can be said that the recommended system is technically feasible, as there are not much complexity in the making this system happen. The needed resources and equipments are already present in the organization and proper efficiency can be gained from these resources by implementing this new management system.

Proposed system is highly economically feasible too. Extra finance will not be needed for the implementation of this system as; everything is available and only needs proper supervision. As stated above the system is efficient, we can take sufficient usability from the system. This will be one time investment and not need any maintenance; states that the proposed system is economically feasible.

This hospital management system is applicable in Windows 2000, Windows 98, Windows NT, and Windows 95, it also supported for the platforms like Macintosh, Applet, and UNIX. The system should be running on the operating systems, which are Windows 2000, Windows 98, and Windows NT and should meet the following requirements:

Windows 200 based computers: 700/850 MHz or larger processor with RAM 512 MB.

Windows 98 based computers: 500/88MHz or larger processor with RAM 32 Mb

Windows NT based computers: 488 / 66 MHz or larger processor with RAM 16 MB

Windows 95 based computers: 486 / 66 MHz or larger processor with RAM 8MB

Input design can be referred to the process of transforming user-oriented input to a computerized based format. It is one of the major crucial parts of the whole system design that requires care and attention. It can be reported that the collection of input data can be the most expensive part for this system. Input design has following objectives:

1. Achieving highest accuracy
2. Producing cost effective method for the input
3. Ensuring that acceptable by the staffs and understandable for them.

The aim of designing the input data is that to make enter easier, eliminate free hand errors, and more logical. An input form will be presented for the format of data fields to be entered. Data entry can also be made online, which led to the use of processor that could accept the commands and the data using a keyboard and analyze those inputs. Based on that, either input will be accepted or rejected. Following are the stages that will include during this process:

• Data Recording
• Data Transcription
• Data Analysis
• Data Control
• Data Transmission
• Re-input Data

Feasibility Studies

Selection of data capture methods and devices should be done in a manner to reduce the stages, which in result will return less errors and cost. The input types can be characterized in five ways: Internal, External, Operational, interactive and computerized inputs. There will be existence of Input before being input to the system. The involvement of capturing data procedure makes Input Design complex for inputting the data into the system.

Outputs design is being focused on communicating the results of processing system to the users, including a documented result that can be used for later purpose. For the users it is the direct and most important source of information. Logical design stage can define the outputs, in negative cases, it could be defined at the early stage of the design about the response, connect, format etc. The output types can be characterized in five ways: Internal, External, Operational, interactive and turn around outputs. All screens are user interactive and informative in a manner that the requirements of the user are meted through queries.

Implementation can be the most practical stage for the project in which the theoretical design will have to turn into a working system. The phases in this section are constructing, then installing, and then operating the new system. One of the crucial stage for the success of the project is the efficiency and affectively of the system. There are certain objectives and activities for the implementation of new system, which are: System Design, End user education, parallel Run, End user training, Post implementation review, and application software training which are explained below:

The nurses and chemist doing daily operational activities will the most concerned individuals in order to make this system successful, which will need training as, this will be a new system for the officers. Training about the actions and commands will be provided to them.

After the first stage the education for the end user will be implemented. This will be completely new system for them and they can feel the system complex and in order to make them comfortable with this system, proper education to them is necessary. This will include lectures and documents about the working and the commands.

After the implementation of first and second stage, this stage will be executed. Proper training is very important in this whole project in order to eliminate or completely minimize human errors. In this training, user will be introduced with the possible errors and the help menu including the screen options description.

Input and Output Design

Regular meeting can be arranged with the officers, management and the programmer in order to monitor the working, sufficiency and problems that are occurring during the execution of the new system.  

It will include verifying the questions: Is ‘Tool-bars’ and ‘pull-Down’ menu are working properly or not? All the menus are properly listed or not? What is the possibility of invoking each menu function with a logical assumption in order to meet the goal? There are possibilities of errors after few days of this implementation. This can lead to following problems, which are first, late response on the problems that are raised. Second, system errors might affect the files and the records that are being saved its processor. The process of testing should focus on the logical intervals of the software in manner to insure that all the statements and codes have been successfully tested. Secondly, Functional interval testing is uncovering the errors and ensuring that the defined input is producing real results and meeting the demands of the user. Modules level training, Program level testing carried out after the integration. Following are the two major types of testing:

It can also be described as “Glass box testing”, “which is a test case design that uses the control structure of the procedural design in order to drive the test cases”. Following tests have been made using White Box Testing, which are: Firstly, Every independent path in the module has been exercised one time. In the proposed system, it is being ensuring that cases were executed and selected passes all the case structures. There were few bugs which have been fixed. Secondly, every logical decision was evaluated for the falsity and truth of the values.

The main focus of the Black box testing was on the functional requirements of the system. Black box testing can help the programmers towards enabling in order to derive a set of input conditions or commands that will properly examine the functional requirement of the system. Black box testing can be stated as an alternating approach to white box testing that can help in uncovering different class of errors that might be left in white box testing. The hidden errors include Performance in data structure, interface, initializing and terminating, and performance errors.

The ethical challenges or issues in using this system within the hospital is can be categorized as: privacy and confidentiality that is being mitigated by using different credentials for different level access, security breaches, which could be stopped from happening by using anti-virus and anti-malware with the system. Data inaccuracy is another ethical issue, for which several testing have been made already.

Implementation

Conclusion

Based on the above report it can be concluded that this project is a humble venture in order to satisfy the needs of effective and efficient system in a hospital including several user friendly coding, which have been adopted for improving the working of project. This package will help in all the ways to manage operational activity within the hospital. Implementation measured is up to the mark with certain bugs and glitches, which can be improved easily. This implementation will save much time for the nurses and will provide exact calculation of the time and cost and finally enhance the performance of the organization.
