Objective: The aim of this study was to evaluate staff experiences of the use of a computer-based concept for lifestyle testing and tailored advice implemented in routine primary health care (PHC). Design: The design of the study was a cross-sectional, retrospective survey. Setting: The study population consisted of staff at nine PHC units in the county of Ostergotland, Sweden. Method: After a computer-based concept for lifestyle intervention had been in operation for 1 year, a questionnaire was distributed to all staff members. The questions concerned experiences of and attitudes to the concept, and comments on addressing lifestyle issues in PHC. Results: Of the 291 potential respondents, 59 per cent returned the questionnaire. Eighty-five per cent found it positive to refer to the computer-based test, and 93 per cent of those who had read the written advice generated by the computer agreed with the advice provided. Seventy-five per cent thought that the concept could have an effect on a patient's lifestyle, and 78 per cent had confidence in the computer-based test. Staff at smaller PHC units had more positive attitudes (p = 0.003) and referred a higher proportion of their patients to the computer-based test than staff at larger units (p = 0.000). Follow-up rates showed no significant differences between the categories. Staff believed that inclusion of more lifestyle areas, e.g. smoking and dietary habits, would make the test more useful. More time, education and the establishment of lifestyle practices were issues suggested in order to enhance the focus on lifestyle factors. Conclusion: Staff members have confidence in the computerized test and consider it a valuable tool. A development towards more lifestyle areas will make it even more useful. (Contains 2 tables.)
