title: Validation of a laboratory and hospital information system in a medical laboratory accredited according to ISO 15189.
abstract: BACKGROUND
  The aim of the study was to present a protocol for laboratory information system (LIS) and hospital information system (HIS) validation at the Institute of Clinical Chemistry and Laboratory Medicine of the Merkur University Hospital, Zagreb, Croatia.
  
  
  METHODS
  Validity of data traceability was checked by entering all test requests for virtual patient into HIS/LIS and printing corresponding barcoded labels that provided laboratory analyzers with the information on requested tests. The original printouts of the test results from laboratory analyzer(s) were compared with the data obtained from LIS and entered into the provided template. Transfer of data from LIS to HIS was examined by requesting all tests in HIS and creating real data in a finding generated in LIS. Data obtained from LIS and HIS were entered into a corresponding template. The main outcome measure was the accuracy of transfer obtained from laboratory analyzers and results transferred from LIS and HIS expressed as percentage (%).
  
  
  RESULTS
  The accuracy of data transfer from laboratory analyzers to LIS was 99.5% and of that from LIS to HIS 100%.
  
  
  CONCLUSIONS
  We presented our established validation protocol for laboratory information system and demonstrated that a system meets its intended purpose.
