Assessing health insurance literacy in Switzerland: first results from a measurement tool.

Background: Health insurance literacy (HIL) is crucial for individuals to make informed-decisions and navigate complex choice-based health insurance systems. However, there is a lack of evidence on HIL in countries outside the US, with Switzerland no exception. Methods: Using the HILM-CH, a survey instrument developed to measure HIL in Switzerland, this study first describes the answers to the HILM-CH. Second, the study uses ordinary least squares and quantile regressions to investigate the associations between the HIL score and demographic, socioeconomic, health, and preference factors in the German, French, and Italian Swiss regions. Results: A third of the population faces difficulties in finding health insurance information. Understanding it and managing the financial aspects of the Swiss health insurance system pose the biggest barriers to the population. The HIL score significantly and positively correlates with age and financial risk, while non-Swiss individuals have lower HIL scores. No association was found between HIL, gender, education and time preference. There is a small health gradient, with more doctor visits associated with higher HIL in the lowest quantiles of the HIL score. Similarly, wealthier individuals in the Swiss German part of Switzerland have a higher HIL when choosing their health insurance. Conclusion: This study provides important insights into Swiss HIL and its associated factors. These findings contribute to the international literature on HIL and highlight the importance of understanding variations in HIL and various factors in choice-based health insurance systems.
