The Free Diagnostic Pathology Software Project arose from the NHS Improvement’s Lean Histopathology Project in the UK. Histopathology laboratories diagnose diseases, particularly cancers, by examining the appearances of the cells in samples of tissue. Many histopathology laboratories are using antiquated reporting software. Upgrading to a more modern system is expensive. Even the more modern systems often lack the technology needed for pathologists to efficiently report complex cases allowing workflow to be visually managed and supporting the use of customisable templates and proformas.
