[영문]OBJECTIVE: Patients' experiences and satisfaction ratings are increasingly used to evaluate quality of care. This study assessed the extent to which outpatient teams, clinics, and health trusts contributed to patients' experiences and to what extent clinicians' evaluations of quality were related to patients' experiences. METHOD:S: A questionnaire was mailed to 15,422 outpatients who attended Norwegian clinics in September 2004; 43% responded. Patients' experiences were measured on an 11-item index and three subscales: outcomes, interaction with clinicians, and information. Aggregated responses from clinicians were linked to the data on patients' experiences. Multilevel analyses were used to divide the variance between the different organizational levels and to assess the relationship with clinicians' opinions and individual-level factors. RESULTS: Data were analyzed for 6,570 outpatients within 222 teams derived from 89 outpatient clinics within 33 health trusts. Differences in patients' scores were determined largely at the patient level, with teams accounting for 2% of the total variance and organizational levels of clinics and health trusts not contributing to patients' experiences. Team-level clinician quality scores were not significantly associated with patients' experiences. Better experiences were significantly associated with patients' female gender, older age, better self-perceived health, absence of an inpatient history, longer treatment episodes, frequent consultations, and waiting times perceived as acceptable. CONCLUSION:S: The organizational contributions to patients' experience scores were minimal. Although clinicians' ratings of quality are not a substitute for patients' perceptions of quality, surveys of outpatients' experiences and satisfaction may not be appropriate for cross-sectional comparisons of health care providers.
