Drop a Patient Set and a Concept (Ontology Term) into the input boxes below, and then click the "View Results" tab to retrieve information about when that concept was observed in the selected patient set. In this example, the results are returned in the standard i2b2 PDO (Patient Data Object) XML format. You may select whether to return information about the patients, events, or observations.

# Example #3 - PDO Request

## Introduction

This plugin demonstrates how to retrieve information using the Patient Data Object (PDO). The PDO is the standard way in which i2b2 encapsulates all patient data. All plugins that need to access patient data must construct PDO Requests and parse the returned PDO Response. The PDO Request takes several input options, including a list of patients, groups of concepts, the list of items to be returned. The PDO Response, dependeing on the input options, might return details about the patients, a list of observations corresponding to the selected concepts, or information about the events during which the observations occurred.

## Instructions

Navigate to the "Specify Data" tab. Then, drag and drop a Patient Set and a Concept (Ontology Term) onto the input boxes. You may optionally select which types of information you want returned. Finally, click the "View Results" tab to view the PDO Response.
