Limitations
SECONDARY
This study has some limitations. One limitation is that it was conducted at a single tertiary academic center. Therefore, the results might not be generalizable to other clinical settings. In addition, we were unable to record the specific QPS questions that participants eventually asked during the visit. A better understanding of how participants used the material in real time and which questions were the most useful should be a focus in future research. Another limitation is that hypothesis testing for the secondary end points is considered exploratory when the primary end point does not show statistical significance, which was the case for this study. Additionally, the study was conducted among ambulatory patients with relatively good functional status. Future studies should include patients in acute inpatient settings, since they might have different symptom severity and therefore different outcomes.
