Evaluation parameters of the MEDIGATE System were assessed using the data that was provided by the physicians after inspecting their patients basing on the abdominal pathologies. The summary of the information that was gathered related to the cause of the diseases, management, or keeping the track of the abdominal pathologies were developed.
The physicians recorded the results of examining their patients manually by writing on a book by using of the pens previously. The information that was collected from this analysis provided the basics of assessing MEDIGATE system 1) comfort of using the system, 2) initial skills that are needed when running the system, 3) ease of understanding how the system is used, 4) problems that are related to the functionality of the system, 5) usefulness, and 6) what is salvaged. This analysis furnished a comparison of the MEDIGATE System and normal pen and paper documentation.
The physician acquires this information basing on the “chief complaint” (through interviewing their patients by asking them some questions like– what made you to come to hospital?), then supporting the chief complaint(s) when describing the “History of Presenting Illness”. Subsequently, the physician goes on to an organized simple query “Review of Systems,” where there are short questions that are asked on different parts of the human body. Similarly, these questions require short answers.
But then, the inspection of the specified part of the body with an aim of identifying the cause of the conditions or problems can be analyzed further (Wiegmann and Shappell 2017).
An investigation that is carried out regarding the part of the body that is having unusual functioning is very important in the entire field of medicine. The physicians identify how the part was functioning previously before developing a problem. This process requires development of a computer system that can assist the physicians in carrying out the examination on their patients.
The application of MITIGATE system in the hospitals has changed the entire processes that are used by physicians to examine their patients. The common methods that are used to record the results of the patient’s examination such as using of a book can also be applied in this system thus enhancing the interaction with its users.
The MEDIGATE System is used in hospitals by physicians to retrieve and generate the information of their patients currently. As specified, the system uses icons in representing different objects. The physicians are also allowed to record the details of their patients that can be used for the future reference in case the problem develops again. Afterwards, the physician can describe the reason for the problem identified in form of drawing representations. Complex of multiple findings in a given region may be formed with various iconic designs, hence depicting graphically a state of associated findings.
The MEDIGATE System centers on helping the medical practitioner in developing and maintaining physical examination findings record. This system keeps the results of the patients after the checkup. These results are stored in this system in form of pictures rather than words for easy understanding by health care professionals. This is facilitated by using icons. The parts of the human body are exhibited in this form to make them clear and visible thus enabling health care professionals to inspect their patients with a lot of ease. Subsequently, a physician can then describe his results regarding the condition of their patients basing on the problem has been detected using this system that is associated with patient’s conditions. The results of different areas that have been specified by physicians can be separated or differentiated using different pictures.
MEDIGATE system has the capability of keeping the information concerning certain conditions in form of pictures. Different objects are kept in this system using bits rather than bitmapped images because of the huge spaces that are occupied by these images when keeping them. These objects that are stored in this system are aware of their properties and the ways on which they are separated from each other. Simply, different objects are used to store different information in this system (Schwedhelm et al 2008).
The health care professionals such as surgeons can interact with this objects that are running currently on the computer system showing a specific part of the human body such as the heart that is being checked at the moment. There are different ways on which the physicians can record their results including using the manual method of sketching their results using their hands or by making different instances of the same objects that were kept in the system early on.
SUMMARY OF RESULTS AND ASSESSMENT OF USABILITY
From the above results, it is evident that up to 70% of designated tasks were successfully completed by the physicians but a paltry 40% of the physicians were able to complete the given tasks. Although many physicians (80%) were able to learn the functions of the system, only half could successfully complete tasks after a period of one-month non-use. This implies that the system is not easily adaptable to the physicians.
As regards efficiency, most physicians took up to 10 minutes to complete a task, 5 of which were spent on unproductive actions, pointing out the need to develop a more simplified user interface to cut down on time wasted on unnecessary functions. However, first time accomplishment of tasks took up to 15 minutes, reducing the suitability of the system when employed in emergency set ups.
On a scale of 1 to 5, most physicians were satisfied (4/5) with using the system voluntarily but embraced the use of advanced features.
The solution to the unique problems attendant upon the MEDIGATE system is based on acting on the usability interface to make the system more adaptable to the physician and not the physician adapting to the system. The process of recording data has been enhanced in the current years as compared to the past. This has resulted in development of many systems that can be used by the physicians while recording their patient’s results.
Human factors are very essential when developing these systems. Over the recent years, developers and programmers of the computer systems have not been incorporating human factors into the process of system designing. Modern developments in system designing has facilitated the development of complicated systems that can be used in the field of medicine by the physicians (Oinas-Kukkonen and Harjumaa 2009).
The properties of the MEDIGATE system are determined using the information that has been gathered by the physicians. This information exhibited the challenges that are encountered when entering the information into the system. In addition, the challenge of using the stored data correctly by the physicians is also expressed. Over the years, programmers and the developers of the systems were concerned much about how the information was to be kept rather than the problems that are encountered while using the system.
Developing a better computer system requires the need of correcting all the errors and problems that are encountered while using the system. Also, incorporating of all the prerequisites that have been specified by the system users is also very crucial. The proposed system must be able to satisfy the needs of its users.
The programmers and developers have developed the MITIGATE system basing on all the necessities that are required when developing and designing modern computer systems. This system has been developed using icons whereby different icons are used to represent different objects.
The principles underlying the process of designing the MEDIGATE System can be incorporated in any upcoming systems that uses the voice identification techniques. Also, they can be incorporated in the systems that uses pens as one of the tools. Therefore, this can enhance the ease of adopting and using the system. MEDIGATE system can be applied in many digital systems enabling them to achieve their purpose and functions.
With the availability of diverse multimedia technologies, the integration of audio and video links may be vey crucial and vital to the MEDIGATE system. It will enable the physician to call up a medical reference or a video picture of a procedure of concern, hence getting prompt feedback and reminders.
It is believed that these principles will play an important role in future computer-based medical information systems by enabling the collection of relevant information and providing for presentation and maximum utilization of the data, hence promoting the ways on which the patients are taken care of, management and controlling of the errors in the systems, and enhancing the researches that are related to the field of medicine.
However adequate analyzation of the functionality of the system is only useful when the defects of the system are dealt upon in a timely manner. Evaluators and designers need an organized list of findings for prioritizing redesign work. The programmers should solve the errors that are detected while the system is functioning.
The report should be arranged according to either areas of the system concerned, or by severity of the problem. For the latter, a five-point scale should be adopted, ranging from ‘would prevent user from proceeding further’ to ‘minor irritation’. Adding a note of the general usability principle concerned may help designers understand why there is a difficulty, but often more particular elaboration will be required. In lieu, sometimes the problem is so apparent that explanation is redundant. A face-to-face meeting may have more influence than a written document alone and this would be the ideal venue for showing short video clips and playing audio records of user problems, (Czaja et al 2009).
Suggested solutions increases the likelihood of something being done. The users can seek the assistance in running and operating the system from the programmers who developed the system, although it has been revealed that this can lead to the development of many problems.
Handling of the computer systems that have been developed is a great challenge to many hospitals. The error can be corrected by involving the system users such as the physicians in all the entire process of testing the system to ascertain that it meets its requirements.
However, the system that has been developed can be susceptible to errors. These can be the errors that were developed during the process of system designing by the programmers and developers of the system. Controlling of these errors is one of the necessities of becoming a good system developer. These errors can be corrected by establishing of a team of experts that will be checking the entire process of designing and developing systems.
