Public needs for information disclosure on healthcare performance: Different determinants between Japan and the Netherlands

The accumulated healthcare performance data related to unwarranted practice variations are not necessarily disseminated to patients and citizens. To clarify the needs for public disclosure, we explored Japanese and Dutch citizens’ preferences and values towards information disclosure and healthcare disparity. Online opt-in survey was conducted and we asked citizens their preference to know about the healthcare performance indicators of regions and hospitals, and their attitudes towards healthcare equity. After a descriptive statistical analysis, Chi-squared automatic interaction detection tree analysis was performed to explore the socio-demographic determinants which were associated with positive value for information disclosure and healthcare equity. Then, we compared the combination of attributes of the highest and the lowest subgroups of each country and compared within and between countries. Last, logistic regression analysis was performed to further evaluate the impact of each determinant. Significant differences were observed between the 2 countries (Japan [JPN] 1038; Netherlands [NL] 1040). The crucial attributes identified were age, sex, educational background, and living area (JPN), along with age and sex (NL). Japanese comprised multiple subgroups with heterogeneous values, showed relatively low interest in knowing the information, and seemed to accept healthcare inequality, especially among urban males aged 20 to 59 years. Contrarily, Dutch people mostly showed high interest in both items. Female and older respondents valued information disclosure highly across countries. To share healthcare performance knowledge and empowering the public, historical, cultural, and socio-demographic context including health literacy of citizens’ subgroups should be considered in making comprehensive public reports.
