1. Expanding on coded valuesources in Observations SurangaNathKasthurirathne Glen McCallum Burke Mamlin

2. Patient Form Data How do we store these values in OpenMRS ? 2

3. Concepts and Observations An Observation is a clinical measurement A Concept describes observational info. Boolean Coded Text Datetime Numeric Complex data types Text Images 3

5. Handlers for Complex data No database changes Supports all possible data types Domain objects External data Easy to introduce new handlers Automatic registration and prioritization 5

6. Flexibility Store data in OpenMRS DB or external DB Use existing features to enhance data input — fieldGen tags (Other options?) Unregister or change priorities easily 6

7. Progress in a nutshell… — Ability to create and override handlers — Ability to create, edit or delete Complex Concepts Complex Obs — Supports all possible scenarios Defined handler class hierarchy and interfaces 7

8. Progress continued…. Extensive validation Prevents loss of data whenever a page is refreshed — Improved unit tests and validators — Documentation — Developer testing All Objectives completed ! 8
