EHR System Functional Model You are the CIO of a 300-physician practice. The board of directors has decided to purchase an electronic medical record (EMR). You have been asked what the role of the HL7 EHR System Functional Model should have on your decision. Explain the direct care functions of the HL7 EHR System Functional Model. Explain the supportive functions of the HL7 EHR System Functional Model. Explain the information infrastructure of the HL7 EHR System Functional Model. Do you recommend that the HL7 EHR System Functional Model should be the basis upon which you evaluate the EMRs? Justify your recommendation. Case 3-9. System Life Cycle You recently heard about the concept of system life cycle in your HIM course. You really do not understand what it is. You know that it has something to do with the different stages of the information system, but you do not understand what those stages are and what would be included in each of the stages. Research the following information about system life cycle and write up your findings. Identify the stages of the life cycle. Describe how you can tell what stage an information system is in. Cite at least two specific examples of how information systems could fall into each of the categories (e.g., update software during maintenance phase). Explain how the HIM professional can be involved in each of the stages.
