This study could be limited by several factors. The first limitation could be due to a socially desirable response bias; some participants might have given what they perceived as the 'right' answers to the questions rather than the answers that reflect their opinion or belief. In order to address this concern, future studies could benefit by using qualitative methods, which provide more reliable results about the motives and opinions of participants. Also, this study was not prospective, so recall bias might have affected the responses of the participants. Furthermore, the extent to which the results of this study are applicable to HCWs such as nurses or physicians who work in internal specialties is uncertain. Future studies that include other HCWs as participants may broaden our understanding of the beliefs and opinions of HCWs, thereby allowing us to state our claims and shape our arguments more precisely. Finally, it should be mentioned that the response rate for this study (61.7%) was slightly lower than is generally expected for a survey. Nevertheless, despite all these methodological limitations, we believe that our findings support our conclusion about the persuasiveness of the presumed consent argument.
