What is Personal Health Assistant (PHA)?
 Patient Version for Medication and Chronic
Disease Management and Authorizing Providers
 Identify Overmedication , adverse interactions, and
adverse reactions
Provider Version for Viewing Patient Data that has
been Authorized
Personal Health Record Microsoft HealthVault
 A Person Can Track Medical Information
 Used as Backend Repository to PHA
OpenEMR Standalone version for Providers
 Seek to Integrate into PHA
 Support Medication Reconciliation

Two Types of ODLs
 Condition/Exercise/ODL
 Collect Patient Entered data on
Condition/Exercise/ODL
Modifying, if necessary, the ODL and Medication
screens that already exist
Hooking the current ODL and Medication screens so
that information is stored in the new classes
Lots of Sample Screens for Conditions Given in the
Rest of this Presentation

Develop Test Java Program with Client Classes that
Gets you Familiar with Retrieving from all Four APIs
 RxNorm, RxTerms, NDF-RT, FDA Daily Meds
Consider Following Decomposition of Project
 Java Test/API Program for Interaction Checking
 Mods to Current Med Screen

Revisions to Medication Screen:
 Organize Drugs by MSHV and OpenEMR
 OpenEMR are read-only - cannot be changed
Link from Med to FDA Daily Meds
New Medication Checking Screen: This can be
 Combined list of meds (MSHV & OpenEMR)
 Returns a list of meds and their interactions
Usage of External Web Services:
 FDA Daily Meds, RxNorm, RxTerms, NDF-RT
