sex, or work position, nor any correlation between these terms and total computer use or user satisfaction. Respondents scored high in computer literacy To assess respondents' computer literacy we asked them about their computer ownership, typewriting ability, prior computing experience in solving specific tasks, highest prior frequency of computer use, and self rated computing skills. The mean summed score of this section was 72.2 out of 100, with little difference between the users of the three electronic medical records systems (69.6-76.0, analysis of variance P=0.006). The correlation with total computer use was 0.39, P&lt;0.001. Computers were available in the respondents' work places Most respondents (203/218 (93%)) had computers in their offices, and 209/216 (97%) had computers available to them in other rooms used for clinical work. However, 85/214 respondents (40%) were weekly or daily prevented from using these computers because others were using them, and 94/214 (44%) were monthly or weekly hindered by computer errors or problems with passwords (3% were hindered daily). Use of the electronic medical records systems was limited Functionality of the electronic medical records systems According to the information provided by information technology staff, most of the clinical tasks listed in our questionnaire were in some way covered by implemented functions of the electronic medical records systems. In general, 15 of the 23 tasks were covered for at least half of respondents: DIPS, Infomedix, and DocuLive supported 19, 16, and 11 of the tasks, respectively (fig 1 ). The systems were mainly used for reading patient
