HIM Director of a local healthcare facility that is in the process of database development

 

 

Imagine you are the newly hired HIM Director of a local healthcare facility that is in the process of database development. First, you need to develop a Data Dictionary (before the actual database development). Which components of the databases would you include in the Data Dictionary for a facility you are working for and why? (Use the following guidelines and an example below):
1. Name of the Data Dictionary table
2. Data elements: Field names/attributes
3. Data type (text, number, alphanumeric)
4. Description of the field/attribute, the reasoning for the choice made
5. Format for collecting the information (e.g., date of birth DDMMYYYY – day, month, year)
6. Number of characters that can be stored (File Size)
7. The range of values (e.g., 1-100).
8. What are the consequences of organizational performance ( when lacking specific organizational knowledge) and compliance in case of a missing Data Dictionary for the databases(s) the organization is developing or using? 
9. How to overcome them?
 

Sample Answer

 

 

 

 

 

 

As the new HIM Director, my first priority is ensuring that our database is built on a foundation of semantic interoperability and data integrity. Without a Data Dictionary, we are essentially building a library without a card catalog—information exists, but it is disorganized and prone to misinterpretation.As the new HIM Director, my first priority is ensuring that our database is built on a foundation of semantic interoperability and data integrity.
