“…The use of OCC has advantages compared to traditional measures, particularly: websites are easy to access and use [1,30] they are a form of information that promotes transparency, since data are made available online and are accessible to most people [28,31]; they are a real-time barometer of public opinion, in a context of rapid and constant change, and allow the identification of prominent issues [11,32]. They can be a substitute, instantaneous or almost in real time, for the analysis of the users' experience, with the possibility of using automated methodologies, which facilitate their analysis [31,33,34] and it is in this sense that the present study will seek to make a major contribution; they offer a convenient, safe, low-cost mechanism for organizations to hear users' voices [31,34], being an important means of alarm to signal the deterioration in the quality of care [16] or, on the other hand, to identify successful practices [31].…”
