Cohort Module

Introduction:

What's a cohort?

•  A cohort consists of a group of patients based on a condition like patients receiving similar kind of treatment which can be monitored over a period of time.

•  Cohort management system unlike patient management system deals specifically to monitoring  and suggesting possible cures to group of cohort members under a specific cohort unlike separate diagnosis for a particular patient.

• We can analyze trends and patterns and this helps in research an policy making

Objective of the Project:

• The purpose is to manage cohort related data

  • cohorts,

  •  cohort types

  •  cohort attributes

  • cohort attribute types

  • cohort members 

  • cohort member attribute 

  • cohort member attribute type

•  Using REST to allow external system integration with cohort module

•  Cohort Management can be performed in two ways

  • Simple Cohorts for single entities

  •  Cohorts including groups or collections like households

Design of the Module:

ER Diagram:

• The module deals with creating cohorts and associating it with cohort attributes which are dependent on cohort attribute types

• Every cohort member who is a patient is associated to the cohort and also it can have cohort member attributes which are dependent on cohort member attribute types.

• Search operations can be performed based on name under the mange cohorts page

• Each of the cohort can have many encounters ,visits and observations which are created utilizing the forms from the HTML Form Entry Module

• The search operation would be based on the cohort unlike in OpenMRS Platform which is based on only patient identifier/names.

• It is also created utilizing the Rest interface from the Rest Module wherein the resources are identified in requests using URIs as resource identifiers to view cohorts, cohort encounters and cohort observations.
  
  

   

Cohort Web Service Web Integration:

• We would be utilizing REST services in our module so that users who are not accessing the OpenMRS Platform can view the available data of the module by sending an HTTP GET or POST request 

• GET Request can be sent to view the data related to cohorts , cohort members, cohort encounters and cohort observations

• POST Request can be sent to add data into the database by sending parameters as a JSON object.
