Leveraging Open Source Technologies

Open Source Technologies

Below is a sampling of some of the MHS’ Open Source Software available to the public, at no cost.

OpenAHLTA

What is OpenAHLTA?

  • Open source version of the DoD’s battlefield electronic health record system (AHLTA-Theater)

  • Operates on a laptop or in a client server environment
  • Supports laptop documentation of clinical care whether connected to a network or as a stand-alone
  • Utilizes a unique “store and forward” capability that allows data to be housed on a local database until connectivity is restored and transmission is possible
