POCA System Overview
The Phonetic and Orthographic Computer Analysis (POCA) program is a software tool that uses an advanced algorithm to determine the orthographic and phonetic similarity between two drug names. The program can compare a drug name against multiple drug names found in several different “data sources” contained in the software. The data sources provided through this download are:
- DrugsAtFDA (updated monthly)
- RxNorm (updated monthly)
- Suffixes in the proper name of biological products (updated monthly)
- United States Adopted Names
This zip file contains both a compiled version of the POCA application and the source code. The compiled version has been tested and installed on a number of computers.
POCA is a web-based application that was originally developed for the Microsoft .Net Framework 1.1 and the Oracle 9i Database. It has now been upgraded to include the following:
- Microsoft .Net Framework 4.0 and the Oracle 12c Database.
- Revised orthographic algorithm (for more information on the revised algorithm, see Medication Errors Related to Drugs
Prior to installing the POCA database and application, it will be necessary to ensure that the Microsoft .Net Framework 4.0 and Internet Information Services (IIS) are installed on the computer hosting the web application, and that Oracle 12c Database software is installed on the computer hosting the database (these may be on the same computer). Following the instructions in the supplied “POCA Installation Guide”, download and create POCA database. The POCA web application files are downloaded to the computer’s hard drive, which will configure the web server.
Once the application is up and running, instructions for using the application can be found in the POCA User Guide file that can be downloaded from the link above. This file is also available from the “Help” link in the application.
