However, some limitations need to be taken into account. Most of the included patients had a mild-stage disease. The use of technical equipment and the long duration of data collection might have influenced this. The (expected) burden of making videos was a frequently mentioned reason not to participate in the first place, and one participating patient withdrew early for this reason. Patients willing and able to use technical equipment – such as the patients included in this study – might be more able to initiate and independently handle changes in care. It is possible that non-participants would have encountered more complex care changes that were more difficult to anticipate, initiate or handle independently. Our population, finally, came from a single regional setting in the Netherlands with well-developed specialized PD care. This population was not inclined to consult their GP for PD-related questions, as we know from an earlier study [16]. Patients in different areas might have different care experiences.
