摘要:Aim: The aim of the study was to assess patient knowledge on reporting of adverse drug reactions. Materials and methods: A prospective study was conducted among 200 patients. The study was based on an original survey composed of 15 single- and multiple-choice questions. The study involved individuals who have experienced adverse reactions as well as individuals who have never experienced any adverse reactions; people over the age of 18; literate; residing in Mazowieckie Voivodeship, who have not been diagnosed with any disease that could compromise their logical thinking skills. Results: The respondents who lived in the city had a greater knowledge compared to the respondents who lived in the countryside (Pearson’s χ2 =47.70, P =0.0013). The respondents who lived in the city were also more statistically likely to provide a correct answer to the question about the type of adverse reactions to be reported (Pearson’s χ 2 =50.66, P =0.012). Statistically significant associations were found between the place of residence of the respondents and the correct answer to the question about the data that must be included in the report on adverse reactions (Pearson’s χ2 =11.7, P <0.0001).
