Danish Physicians' Views on the Appropriateness of the Involvement of Patients with Type 2 Diabetes in Regulatory...

Regulators, the pharmaceutical industry, and patient organizations expect an increased inclusion of patients' risk preferences in medical regulatory decisions, for example, with regard to market approval. Merging of input from patients with, for example, multiple sclerosis, with expertise from health professionals in regulatory decisions has already occurred. The complex task of involving larger and more heterogeneous patient populations (e.g. with diabetes mellitus, asthma), however, remains.

This study aimed to understand physicians' experiences with factors influencing patients with diabetes mellitus perceived risks of their medicines and to explore how physicians, based on these experiences, perceive patients with diabetes to be suited for involvement in regulatory decisions. This study will provide knowledge that can improve the inclusion of heterogeneous patient groups in regulatory decisions.

We conducted five semi-structured interviews with physicians with different types of experiences with patients' risk perceptions (for example, being in contact with individual patients vs. being involved in developing guidelines at the population level) and one focus group interview with eight general practitioners in Sjælland, Denmark. We applied a thematic analysis to explore physicians' experiences of the risk perceptions of patients with type 2 diabetes and their perceptions of patients' fitness for involvement in regulatory decisions.

The risk perceptions and preferences of patients with diabetes were perceived to be rather diverse. Four drivers behind this diversity were described: past experiences, personality, prognosis ability, and knowledge. The legitimacy of patient preferences was not questioned, but the diversity of risk perceptions made the respondents question the existence of a uniform 'patient voice' useful for regulatory decision making.

The respondents acknowledged the relevance and legitimacy of the patient perspective, but it was a concern that patient risk perceptions, at present, are too diverse to be included in regulatory decisions. Whether patients make regulatory decisions as perceived by physicians needs to be confirmed by future studies.
