title: [Development of a Web-based laboratory data browser integrated with heterogeneous clinical information].
abstract: OBJECTIVE
  To demonstrate the feasibility of a Web-based laboratory data browser integrated with heterogeneous clinical information in a hospital setting.
  
  
  METHODS
  A Java-based web application was developed in-house, using free open-source software. The server side manages queries to heterogeneous hospital databases containing patient data. Order entry information including laboratory test results, drug prescriptions, injection orders, physiological test orders and, imaging test orders, was retrieved from a replication database, and integrated with nursing data from a nursing system database. The result was visualized in a time-series table format, and accessed by web browsers on computers connected to the hospital intranet.
  
  
  RESULTS
  The laboratory data browser system achieved practical response times over huge databases (> 90 million records). The medical personnel accepted the system well, and applied the system to various clinical situations.
  
  
  CONCLUSIONS
  Integrating heterogeneous data from hospital databases in a Web-based laboratory data browser is a practical approach. Presenting relevant medical information simultaneously added value to the laboratory data, and may promote better medical management.
