Pharmacy Re-Engineering (pre) Application Program Interface (api) Manual

Introduction

Transition to the new Pharmacy Re-Engineered system eliminates the VistA Pharmacy files currently referenced. Therefore, all existing references (direct global reads/writes, VA FileMan reads/writes) to all pharmacy application files must be replaced with Application Programmer Interfaces (APIs).

This Pharmacy Re-Engineering (PRE) Application Program Interface (API) Manual is designed to document the APIs provided by the Pharmacy suite of applications consisting of the following:

• 
  National Drug File (NDF)
  
• 
  Bar Code Medication Administration (BCMA)
  
• 
  Outpatient Pharmacy (OP)
  
• 
  Inpatient Medications (IPM) – Unit Dose and IV
  
• 
  Inpatient Pharmacy Automatic Replenishment/Ward Stock (AR/WS)
  
• 
  Controlled Substances (CS)
  
• 
  Drug Accountability (DA)
  
• 
  Consolidated Mail Outpatient Pharmacy (CMOP)
  
• 
  Pharmacy Data Management (PDM)
  
• 
  Pharmacy Benefits Management (PBM)
  
• 
  Pharmacy Prescription Practices (PPP)
  

A table of all currently active Pharmacy APIs can be found following the Interfaces section. Each application has a section that begins with a list of all the associated active (supported) and inactive APIs.

Term	Definition
Encapsulation	Encapsulation provides a form of “logical data independence.” We can change the implementation of a type without changing any of the programs using that type. Therefore, the application programs are protected from implementation changes in the lower layers of the system.
