Examples of Databases in Healthcare Patient Billing Patient Demographics Appointment System Centralized physician order entry (CPOE) In the doctors office you would find the following typical databases, either on paper, or in an electronic format. When you look at hospitals you add a new layer of complexity. While it is known the CPOE is shown to increase compliance with formularies, and with evidence based guideline, decrease adverse drug events, order duplications and time to receit of services, many hospitals have not implemented these systems because of expense, training and so forth.

Goals of Design Process Understand your data and why tracking Eliminate duplication data Eliminate redundant data Eliminate meaningless data Promote accuracy and consistency of data 11/19/2018
Goals of Design Process Insure ability to retrieve needed information Support business functions using it Easy to use Lends itself to future growth 11/19/2018
Process Step 1 What is the purpose of the database? What information do I want to get out of it? What should the reports look like? What am I going to do with this information? Step 2 What data do I need to collect to provide this information? Define fields, tables Design data entry forms Ask yourself, How much can I pay to get this developed? 11/19/2018
Big Questions in Healthcare Where is the data going to live? Who owns the data? Who inputs the data? Who can access the data? How does the data get into the system? Can we share data? 11/19/2018
