HEALTH DATA COLLECTION TOOLS

Requirements of Past, Present, and Future

E.D.G.E. system (2006) was the surveillance tool of choice for data collection.

Required multiple pieces of equipment: Bar code scanner, laptop, PDA, GPS card, numerous computer updates, a personnel support.

Time consuming: Required daily upload and download to the laptop.

System has proved to useful, yet complicated and expensive to maintain due to the total number of parts and old technology.

Requirements of Past, Present, and Future

2009-Migration to Android Smartphone. This single device replaces the bar code scanner, program and the computer/PDA.

EpiCollect Data Collection system (Imperial College) – Open Source (O/S) is Free and data collected in a relational type database system.

Requirements: 3rd party contract for Software support ($$$).

Requirements of Past, Present, and Future June-August 2011

ODK (Open Data Kit) Collection System –Univ. of Washington) – is chosen by Taskforce and the DOLF Project

Open source Android based O/S compatible with the Smartphone

Non-relational database collection system. Individualized surveys are easily constructed and linked to the Person ID

Requires Google Account for Data storage (Cloud technology), Google Docs application for the Smartphone and data can be auto-summarised to an accessible web portal.

Additional contracting is NOT needed. ODK’s core developers are researchers at the

University of Washington’s Department of

Computer Science and Engineering

ODK SYSTEM VERSUS EPICOLLECT Overview of Expenses:

3rd party support contract is not needed.

Free ODK Program, Google Gmail Account, Docs App, Cloud, Bar Code Scanner App.

No need for additional server or Personnel

Other benefits:- (Not possible with EpiCollect)

No need to develop desktop based applications

Easily create uncomplicated surveys to country’s needs and language

Easily back up data onto a netbook and the cloud via 3G or Wi-Fi

Confirm the data transfer by accessing Google docs (raw data)

Dedicated portal access through Taskforce’s website

DOLF ODK Webpage provides overview of data current data uploaded as well as specified summary reports

Linked to only one variable (Less complicated)

Easier on the staff and enhances the quality of data

New system does not require you to look up individuals or sync data before entering lab results!
