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.
