Challenge

HL7 v2 is used worldwide to solve interoperability problems among clinical systems. It is still the reference version of the IHE (Integrating Healthcare Enterprise) consortium. The increasing diffusion of the HL7 v2 standard has spurred the development of several software libraries aimed at simplifying raw messages management. The diffusion of the Python programming language has been increasing over the years, particularly in the scientific domain. The reasons for this popularity may be attributable to the language being relatively easy to learn and offering high programmer productivity.

Overview

HL7apy is a lightweight Python package to intuitively handle HL7 v2 messages according to HL7 specifications. The library offers means to create, parse, navigate and validate messages. The main features includes:

  • message parsing;
  • message creation;
  • message validation following the HL7 xsd specifications;
  • access to elements by name, long name or position;
  • support to all simple and complex data types;
  • encoding chars customization;
  • message encoding in ER7 format and compliant with MLLP protocol.

Currently supported HL7 versions are: 2.2, 2.3, 2.3.1, 2.4, 2.5, 2.5.1, 2.6, 2.7, 2.8, 2.8.1, 2.8.2
