Modernizing VistA, ClearHealth's Invaluable Lessons from 'Legacy' ...
summary
ClearHealth rewrites VistA into a horizontally scalable web system running a LAMP stack with memcache, MySQL, PHP and some C++ and extracts MUMPS clinical rules into XML; it supports a 40-site network that handles 1.5M encounters/year and operates across ~400 organizations. Workflows, messaging and alerts are integrated and prove usable in VA sites, but implementations take months, many providers rate themselves novice to intermediate (65%), and some specialties hit hard limits, so VistA’s documentation and community on va.gov and GitHub (GPL) are essential.
