conduct a heuristic evaluation utilizing Nielsen’s Rating scale to evaluate our mobile EMR system and obtain a better understanding as to what problems persist with our prototype. The scale should be based on a system that ranges from 0 to 4 (0= don’t agree there is a problem, 1= cosmetic problem only, 2= minor usability problem, 3= major usability problem, 4=usability catastrophe).

Our mobile EMR system:
Analyzing all aspects of a system where patients will benefit before and after discharge will be important to the design. How the user interface is designed and how patients and providers interact with it, will determine its success. We had to look into prior research relating to patient satisfaction, patient-provider communication and EMR use. In order to successfully implement this with patients in an inpatient setting, there had to be ease of use regarding the layout of the software. As patients come from all different backgrounds such as education and the use of various languages (different backgrounds), the mobile EMR would fill the gaps to provide understanding to these individuals. It’s crucial to keep in mind where patients struggle such as technology expertise, as well as the state of the condition they are in while in the hospital. Patients who are under distress may not comprehend what is being discussed with them which is unfair. After being discharged, individuals should be aware of what was discussed, and how to proceed forward such as scheduling follow ups with their provider, and how to take action to prevent returning to the hospital. To tackle the issues we hope to solve with the mobile EMR, we had to utilize other research that has been done regarding patient engagement, participation and electronic medical record use within the inpatient hospital setting. The research others have completed prior will assist in strengthening our testing, requirements analysis, prototype design, and evaluation of our product. Patients may have elementary levels of education or an advanced level of education. We need to keep in mind the wording, text font, and sizes that are present on the EMR as it needs to be legible to understand for all. For example, instead of using the word patient literature, we will use patient education. If we create an intricate user interface where a portion of the users wouldn’t understand, then it would not accomplish our goals. Another aspect we have to take into consideration is the placement of buttons and interface for the provider’s use. One of the goals is to reduce documentation burden, which would allow physicians to have more time caring for patients. If buttons are not easily accessible when reviewing a patient’s chart on the tablet, then that would increase the time that the physician is spending with one patient. In order to design an efficient mobile EMR system that patients would have the ability to use, we would need to understand where to place certain features such as visualizations. For example, patients need an easy to use system in order to navigate the features. Does it make sense to put the buttons leading to specific features on the top of the ipad screen or on the bottom. We ruled out using written tutorials as we are unaware of the average level of education the patients have. Our proposal is to utilize a video tutorial for patients with low to high literacy level to follow along on the iPad.
Before beginning the actual design of our product, we have to understand the everyday tasks the hospital staff have involving the care of the patient. This is key to constructing a system where patient satisfaction is increased along with the outcome that the patient maintains a better quality of life. We plan to utilize field usability testing with the use of video analysis. This may be intrusive to some as the participant will be on camera while performing tasks. They will be reminded that the video will not be shared, will be kept confidential, and only be recorded while using the device. We would be able to see how well our mobile EMR is being used based on where we designed and placed buttons. This would allow for us to see the amount of time it takes for both clinical staff and patients to utilize the different features. We also would like to utilize a think aloud protocol towards the patient use of the system. We felt that there was a need to ensure when the patient is reading the educational material, that they are understanding it. This could show if the type of educational material that is being brought to the patient is difficult to understand. The use of both video analysis and think-aloud, we can review their body language and ensure that they are retaining the information that is being taught to them as well as if they comprehend what the clinical staff are explaining to them. Having the screen captured would also allow for us to collect data to see if our prototype system shows ease of use. Analyzing the performance of the end user would also allow us to examine the amount of time taken to complete tasks and how long. Based on the information that is gathered, from our analysis we can take this back to the design team to make any proper changes that are necessary.
A more patient centered EMR is what we have implemented as it would provide these features into one tablet. Patients would be able to visually see what their vitals are. They would be provided education materials and have it reviewed with them while in an inpatient setting. They would also have the convenience of interpretation services if they speak another language. Physicians can also use this EMR if telehealth services are needed. Another benefit to mobile EMR would be the advantage of using less paper-based records, and increased patient safety during COVID.
