title: Determinants of continuance intention in a post-adoption satisfaction evaluation of a clinical information system.
abstract: OBJECTIVE
  The evaluation of end-user satisfaction is an essential part of any clinical information system (CIS) project. The purpose of this study is to evaluate the determinants of CIS continuance intention in a late post-adoption phase at the Georges Pompidou University Hospital (HEGP) in Paris.
  
  
  METHODS
  We designed an electronic survey instrument based on an IT post-adoption model (ITPAM) developed from three previous models, i.e., the Delone and McLean Information Success Model, the Davis TAM model and the Bhattacherjee information system continuance intention model.
  
  
  RESULTS
  419 questionnaires were collected from CIS users directly involved in patient care. The perceived CIS quality, usefulness and user satisfaction are significantly lower for medical professions than other professional groups. Continuance intention is very high within all professional subgroups. In a multiple regression analysis, the global satisfaction (R(2) = .780) was positively and significantly correlated with CIS quality, confirmation of expectations and perceived CIS usefulness. The continuance intention (R(2) = .392) was positively and significantly correlated with perceived CIS usefulness, confirmation of expectations and global satisfaction.
  
  
  CONCLUSIONS
  In a late post-adoption CIS deployment phase, continuance intention does not significantly depend on individual end user characteristics but is significantly associated with the perceived CIS usefulness, confirmation of expectations and global satisfaction.
