The first principle is simplicity. Simplicity is an important rule that providers should have on their screen. when the provider opens the screen the screen should have the important information on it, such as the information that the provider only needs that contains difference in ability to show complex material in an understandable way”.( Usability and Human Factors, n.d.) Displays That are not necessary to the task should be eliminated. Displays should stand out, clear and everything should be straightforward like the function options. It should not cause a distraction to the provider. As healthcare advances it is very important that this rule should be applied to ensure the patient’s safety. The second principle I found that would prevent prescription mistakes from happening in the future is forgiveness and feedback. …show more content…
Having feedback of what the provider has done would help increase patient safety. Also help the doctors know what they have done. Feedback is like a summary for example once the provider hits submit a feedback screen pops up to ensure the provider if that what they really wants to do. Good feedback information provides the consequence of the action they would take. Forgiveness allows the provider to explore the system without getting penalty such as them losing their job or causing confusion. This approach allows the provider to learn more about the system. Forgiveness and feedback work great together to prevent the user errors. ( Healthcare Information and Management Systems Society, 2009) The third major principle is effective use of language. This mean that the language used in the EMR should be clear. There should be no words related to, technology, computers and database. (Healthcare Information and Management Systems Society, 2009) Text should never be presented in upper case. This makes it difficult for the provider to read and takes longer to read. The provider should be familiar with the language when using the system. The fourth rule is efficient interactions this means that there’s should be shortcut for experienced providers. When they want to order something, all the information should appear there so they don’t have to go through all the steps again. Additionally, minimize cursor movement and visual scanning, this would be easy for the provider to miss information if they have to scroll sideways or upwards. “Fitt’s law is a discovery of human movement that the time taken to hit a target is proportional to its distance and inversely proportional to its size”. (Usability and Human Factors, n.d.) Both visual scanning and excessive cursor movement cause the provider frustration. The fifth principle is minimize cognitive load. Providers are under pressure during
