Objective. Publicly available information on hospital performance is increasing, with the aim to support consumers when choosing a hospital. Besides general hospital information and information on outcomes of care, there is increasing availability of systematically collected information on experiences of other patients. The aim of this study was to assess the influence of previous patients' experiences relative to other information when choosing a hospital for surgical treatment. Methods. Three hundred thirty-seven patient volunteers and 280 healthy volunteers (response rate of 52.4% and 93.3%, respectively) filled out an Internet-based questionnaire that included an adaptive choice-based conjoint analysis. They were asked to select hospital characteristics they would use for future hospital choice, compare hospitals, and choose the overall best hospital. Based on the respondents' choices, the relative importance (RI) of each hospital characteristic for each respondent was estimated using hierarchical Bayes estimation. Results. Information based on previous patients' experience was considered at least as important as information provided by hospitals. "Report card regarding physician's expertise" had the highest RI (16.83 [15.37-18.30]) followed by "waiting time for outpatient clinic appointment" (14.88 [13.42-16.34]) and "waiting time for surgery" (7.95 [7.12-8.78]). Patient and healthy volunteers considered the same hospital attributes to be important, except that patient volunteers assigned greater importance to "positive judgment about physician communication" (7.65 v. 5.80, P < 0.05) and lower importance to "complications" (2.56 v. 4.22, P < 0.05). Conclusion. Consumers consider patient experience-based information at least as important as hospital-based information. They rely most on information regarding physicians' expertise, waiting time, and physicians' communication when choosing a hospital.

Objective: To assess the impact of quality of care and other hospital information on patients' choices between hospitals. Methods: 665 former surgical patients were invited to respond to an Internet-based questionnaire including a choice-based conjoint analysis. Each patient was presented with 12 different comparisons of 2 hospitals, with each hospital characterized by 6 attributes containing 2 levels. Hospital attributes were included if frequently reported by patients as most important for future hospital choices. These included both general hospital information (e.g., atmosphere), information on quality of care (e.g., percentage of patients with "textbook outcome"), and surgery-specific information (e.g., possibility for minimally invasive procedure). Hierarchial Bayes estimation was used to estimate the utilities for each attribute level for each patient. Based on the ranges of these utilities, the relative importance of each hospital attribute was determined for each participant as a measure of the impact on patients' choices. Results: 308 (46.3%) questionnaires were available for analysis. Of the hospital attributes that patients considered, surgery-specific information on average had the highest relative importance (25.7 [23.9-27.5]), regardless of gender, age, and education. Waiting time and hospital atmosphere were considered least important. The attribute concerning the percentage of patients with "textbook outcomes" had the second greatest impact (18.3 [16.9-19.6]), which was similar for patients with different adverse outcome experience. Conclusions: Surgery-specific and quality of care information are more important than general information when patients choose between hospitals.
