INTRODUCTION
Nursing informatic nurses must commonly read ERDs to determine the data contained in a table and to determine which data fields are in which table. Reading ERDs can also help determine dependencies between data fields. This information is crucial in understanding which table to add a data field into and which tables contain the data needed for a dashboard or report.

For this assessment, you will construct an ERD for a database management system (DBMS) using Microsoft Visio or an equivalent drawing tool. Your ERD will contain one parent table, one child table, and three lookup tables. After you have constructed your ERD, you will reflect on your experience in a written paper.
SCENARIO
You are a nurse informatics specialist at a regional health center in the Midwest where the emergency department (ED) has recently experienced an increased number of asthma-related symptom complaints from school-age children. An ED pediatric nurse practitioner noted a pattern in these complaints that indicated asthma symptoms were not being well managed. To address this community-wide issue, an interprofessional team of ED providers, community pediatricians, nurses, and health educators were called to brainstorm ideas.

The team is currently developing an asthma intervention program for children with asthma. To measure the effectiveness of their work, the team decided to collect and analyze data to establish a baseline before implementing the new asthma intervention program. This baseline data was collected using a paper-based data-collection form, which was distributed to the parents of all children attending schools in the county. This initial form was designed to gather information on personal identifying factors, demographics, relevant medical history, and asthma symptoms. A follow-up survey will be triggered by a clinical decision support (CDS) alert the team plans to put into the health information system. By establishing a baseline, the team can compare the initial data to additional data collected in the post-implementation survey.

The team received more than 500 responses to the initial survey and realized the team did not have the knowledge, skills, or abilities to manage the data for this project. Team members have come to you for help with designing a system to collect, manage, and analyze survey data. You have been given the data-collection survey form and have been instructed to create a DBMS to store this initial data set and the follow-up survey data. The team then wants you to create a CDS alert to support this project in the ED’s health information system.

You reviewed the form and created the attached “Code Sheet for ERD” with all the data elements on the form. On the code sheet, you clustered the data elements into tables. You determined there will be one parent table that contains the patient’s personal identifying information and demographics. You have also determined there will be one child table that will contain the repeated survey data—pre- and post-intervention. You also noted that the system will need three lookup tables for drop-down boxes. By creating the correct relationship between the parent and child tables, it will be possible to conduct statistical analyses that will determine the effectiveness of the educational program by comparing pre-intervention survey responses to post-intervention responses.

After clustering data elements and determining relationships, you will create a logical data model of the database. To create the data model, you will translate the data field names on the attached “Code Sheet for ERD” into an ERD through your drawing tool. Using the table names and field names, you will attach the tables together with appropriate crow’s foot notation, indicating cardinality or ordinality,) between the tables.
REQUIREMENTS
Your submission must be your original work. No more than a combined total of 30% of the submission and no more than a 10% match to any one individual source can be directly quoted or closely paraphrased from sources, even if cited correctly. The similarity report that is provided when you submit your task can be used as a guide.
You must use the rubric to direct the creation of your submission because it provides detailed criteria that will be used to evaluate your work. Each requirement below may be evaluated by more than one rubric aspect. The rubric aspect titles may contain hyperlinks to relevant portions of the course.
Tasks may not be submitted as cloud links, such as links to Google Docs, Google Slides, OneDrive, etc., unless specified in the task requirements. All other submissions must be file types that are uploaded and submitted as attachments (e.g., .docx, .pdf, .ppt).
For this assessment you will create a logical ERD through Microsoft Visio or another drawing tool, using the “Code Sheet for ERD” supporting document. You will then write a paper reflecting on your experience.

2.  Explain how your thinking regarding data modeling and database management systems evolved while working on this task, including specific examples.
3.  Explain how the survey information could be shared if a patient is seen outside of the health system network by addressing the following points:
a.  Explain how interoperability supports the sharing of information between electronic health record systems.
b.  Explain a regulatory mechanism that ensures the privacy of protected health information (PHI) when sharing information.
4.  Describe a CDS alert that could be created to support this project, and include the following:
?  which clinicians would see the alert
?  when the CDS alert would appear (i.e., trigger) for a clinician
?  what the CDS alert would say
?  the reasoning for or against the CDS alert being a hard stop for clinicians
5.  Explain how the knowledge and skills you have acquired during this course inform your understanding of the roles and responsibilities of a nurse informaticist in a work setting.
C.  Incorporate the following components of APA style and formatting into your paper:
?  bias-free language
?  objectivity, credibility of sources, and an evidence-based approach
?  APA-specific rules regarding verb tense, voice, and perspective
?  APA-specific formatting rules for in-text citations and references, margins, spacing, numbering, and indentation for the title page, main body, and appendices of your paper, including headers, bulleted and numbered lists, and tables and figures
D.  Demonstrate professional communication in the content and presentation of your submission.
