Transparency and public accountability are two essential aspects of public administrations because they help to prevent possible cases of corruption and encourage citizen participation. In this sense, transparency is a communicative, not merely administrative or legal, process between public institutions and citizens. The main objective of this study is to identify predictive factors of transparency in government healthcare centers in Chile, Colombia, Ecuador, and Spain in 2021. To do this, we analyzed the websites of 64 public administrations from these countries. Content analysis was applied to assess the presence of 24 indicators on each website. The results for the studied cases reveal an association between the level of transparency and three factors: healthcare systems, internet access, and administration levels. We also identified a predictive factor that should be considered in future studies on the transparency of healthcare websites: the likelihood of decreased transparency was reduced by 91% for public healthcare systems (Ecuador and Spain) as opposed to mixed public –private healthcare systems (Chile and Colombia). We thereby conclude that the involvement of the State, at least in matters related to the healthcare field, favors greater access to information by the community, at the same time as providing greater social responsibility because of substantial communication of the activities carried out by these centers, as well as how and by whom.
