Introducing a module for laboratory test order entry and reporting of results at a hospital ward: an evaluation study using a multi-method approach.

The medical record system DocuLive EPR was installed at a "typical" ward at the Central Hospital of Akershus. Modules for laboratory order entry and reporting of results were evaluated prospectively using several information sources (hospital information systems, telephone records, user survey, semi-structured interviews with key informants). The main findings are discussed, and the lessons learned from the evaluation project are presented.
