Scenario: A large, multisite health care organization is preparing to transition from paper-based records to an EHR. As an INS, you are asked to be a member of the team overseeing the project. The project will incorporate all areas of the organization and it is just in the early phase. The organization wants the EHR to be up and running within the next 18 months but is asking that it be completed as early as possible. 

Select an appropriate SDLC model for this project and justify the selection explaining why you chose that approach. Your model choices are:

Waterfall model

Rapid prototyping or development

Object-oriented systems development

Dynamic system development method

The organization is seeking to meet Stage 3 Meaningful Use requirements by the Centers for Medicare & Medicaid Services (CMS). It has chosen to meet the following objective: Implement clinical decision support (CDS) interventions focused on improving performance on high-priority health conditions.

• The high-priority condition is diabetes. Not only will this mean reporting on diabetes quality measures, but it will also have to meet the stage 3 requirement the organization wants to focus on: clinical decision-support interventions relating to the prevention of type 2 diabetes. 
• The team has assigned you the task of conducting an informatics needs assessment to determine how the EHR can be used to accomplish this. 
• For your assignment, complete the following:
• Describe the steps involved in completing an informatics needs assessment.

While conducting the needs assessment, consider the following:

What data will need to be collected? 

How will patients be identified as prediabetic?

What will determine which patients will be targeted with an intervention?

What elements within an EHR can be used to help facilitate prevention?

What features does an EHR have that can support clinical decision-making?

Present the results of your needs assessment. How will the results influence the design of the EHR?

Explain your function as an INS in each phase of the SDLC; include the role you would play during each phase of implementing the EHR. Note: Consider reviewing the INS scope of practice before answering this question.

• Describe your role as an INS in testing the systems, including functionality, integrated testing, and regression. How will the data be tested to ensure validity and reliability?
• Describe how the INS supports an efficient and effective user experience through usability testing, human factors analysis, and HCI.
• Provide at least 3 examples of how the INS monitors system performance.
