Primary analysis
HAD, anxiety
The main analysis consists of comparing the patient satisfaction scores between the two groups, RFID vs. gold standard, and, if the difference in mean scores is clinically significant (difference of about 20%), to test whether it is statistically significant using Student’s t-test or a non-parametric test depending on the nature of the data. A propensity score matching will be performed beforehand to compensate for the non-randomized design of the study. We will include in the calculation of the propensity score the anxiety measured by the HAD scale at inclusion, the only measurable confounding factor we estimate being related to the primary outcome.
